Abstract Background: Facial nerve dysfunction is the principal postoperative complication related to parotidectomy. Objective: To test the hypothesis that the modified Sunnybrook Facial Grading System (mS-FGS) is superior to the original S-FGS in the assessment of facial nerve function following parotidectomy. Methods: Prospective, longitudinal study evaluating patients with primary or metastatic parotid neoplasms undergoing parotidectomy with facial nerve-sparing between 2016 and 2020. The subjects were assessed twice, on the first postoperative day and at the first outpatient evaluation, 20-30 days post-surgery. Facial assessments were performed using the original and modified (plus showing the lower teeth) versions of the Sunnybrook System and documented by pictures and video recordings. Intra- and inter-rater agreements regarding the assessment of the new expression were analyzed. Results: 101 patients were enrolled. In both steps, the results from the mS-FGS were significantly lower (p < 0.001). Subjects with a history of previous parotidectomy and those who underwent neck dissection had more severe facial nerve impairment. The mandibular marginal branch was the most frequently injured, affecting 68.3% of the patients on the first postoperative day and 52.5% on the first outpatient evaluation. Twenty patients (19.8%) presented an exclusive marginal mandibular branch lesion. The inter-rater agreement of the new expression assessment ranged from substantial to almost perfect. The intra-rater agreement was almost perfect (wk = 0.951). Conclusion: The adoption of the Modified Sunnybrook System, which includes evaluation of the mandibular marginal branch, increases the accuracy of post-parotidectomy facial nerve dysfunction appraisal.

Resumo Antecedentes: A disfunção do nervo facial é a principal complicação pós-operatória relacionada à parotidectomia. Objetivo: Testar a hipótese de que o sistema Sunnybrook de graduação facial modificado (mS-FGS) é superior ao S-FGS original na avaliação da função do nervo facial após parotidectomia. Métodos: Estudo longitudinal prospectivo avaliando o pós-operatório de pacientes com neoplasias parotídeas primárias ou metastáticas, submetidos à parotidectomia com preservação do nervo facial, entre 2016 e 2020. Os indivíduos foram avaliados duas vezes, no primeiro dia de pós-operatório e na primeira avaliação ambulatorial, 20-30 dias após a cirurgia. As avaliações faciais foram realizadas usando as versões original e modificada (que incluem mostrar os dentes inferiores) do sistema Sunnybrook e documentadas por fotos e vídeos. Foram adicionalmente analisadas as concordâncias intra e interexaminadoras da avaliação da nova expressão. Resultados: Cento e um pacientes foram incluídos. Em ambas as etapas, os resultados do mS-FGS foram significativamente menores (p < 0,001). Indivíduos com história de parotidectomia prévia e aqueles submetidos ao esvaziamento cervical apresentaram comprometimento mais grave do nervo facial. O ramo marginal mandibular foi o mais afetado, acometendo 68,3% dos pacientes no primeiro dia de pós-operatório e 52,5% na primeira avaliação ambulatorial. Vinte pacientes (19,8%) apresentaram lesão exclusiva do ramo marginal mandibular. A concordância interexaminadores da avaliação da nova expressão variou de substancial a quase perfeita. A concordância intraexaminador foi quase perfeita (wk = 0,951). Conclusão: A adoção do sistema Sunnybrook modificado, que inclui a análise do ramo marginal mandibular, aumenta a precisão da avaliação da disfunção do nervo facial pós-parotidectomia.

Abstract Introduction Supracricoid laryngectomy (SCL CHEP) removes ~ 70% of the larynx, resulting in structural rearrangement and modification of the swallowing mechanism, promoting chronic dysphagia. One of the consequences of this new physiology is the formation of pharyngeal residues that can increase the possibility of aspiration. The formation of residues after SCL CHEP, its functional consequences, and its influence on quality of life (QOL) is still poorly described in the literature. Objective To investigate and compare the association between self-reported QoL and objective assessments of swallowing function in patients undergoing SCL CHEP. Methods A cross-sectional study was performed from 2018 to 2020 in a reference service for head and neck surgery in Brazil. A total of 860 swallowing videofluoroscopy images were evaluated using the Penetration and Aspiration Scale (PAS) and Dynamic Imaging Grade of Swallowing Toxicity (DIGEST). Results In a group of 86 patients, there was a significant relationship between oncological staging and the global (p<0.001) and total (p = 0.002) QoL domains. There was a negative correlation between the DIGEST scale and the emotional domain of the QoL protocol (p = 0.045). The swallowing function proved to be relevant for QoL. Conclusion The PAS scale did not show any correlation with QoL. The functional performance of swallowing according to the DIGEST scale was coherent with the QOL scores. It is suggested that the residue may be a more relevant aspect for QoL than the aspiration, making DIGEST a promising tool in the assessment of dysphagic patients.

ABSTRACT Objective: To describe the correlation between the residues, their anatomical location and the presence of laryngotracheal penetration and aspiration in patients after supracricoid laryngectomy undergoing cricohyoidoepiglotopexy reconstruction. Methods: This study included 70 patients treated by supracricoid laryngectomy with cricohyoidoepiglotopexy reconstruction in a referral national cancer hospital. The patients were submitted to swallowing videofluoroscopy, and the findings were classified by the penetration and aspiration scale. The images were described observing the presence or absence of residues and their anatomical location. Results: The prevalence of penetration in this study was 68.6% and aspiration was 34.3%. An association was found between the presence of residue on the tongue (p=0.005), posterior pharyngeal wall (p=0.013), pyriform recesses (p=0.002), valecula (p=0.061), and laryngeal penetration. The residue in the upper esophageal sphincter (p=0.039) was associated with the occurrence of laryngotracheal aspiration. Conclusion: Patients undergoing supracricoid laryngectomy with cricohioidoepiglotopexy reconstruction have food residues in different anatomical regions after swallowing. Penetration was associated with the presence of residues on the base of the tongue and posterior pharyngeal wall. Aspiration was associated with the presence of residues in the upper esophageal sphincter.

ABSTRACT Background: The aim of this study was to address the first cases of TOETVA done in Brazil, by TOETVA-Bra study group, regarding safety and complications. Materials and Methods: Series of the first 93 TOETVAs cases in Brazil. All authors except LPK, AJG JOR and RPT received TOETVA training including cadaveric hands-on in Thailand or United States (Johns Hopkins Medicine) during 2017. After they came back to Brazil and started doing their first TOETVA cases in the cities of Rio de Janeiro, Sao Paulo and Chapecó they agreed to collaborate and gather data using an online spreadsheet. All patients were submitted to the technique described by Anuwong. Results: A total of 93 patients underwent TOETVA. Most patients (58.1%) were submitted to total thyroidectomy and 59.1% had benign disease. Two patients (2.2%) needed conversion to open surgery. Five patients (9.3%) developed transient hypoparathyroidism and there were 3 (2.0%) temporary recurrent laryngeal nerve palsy. There was one (0.7%) permanent unilateral palsy. Twenty patients had some sort of complication, 16.1% were minor and 5.4% were major. A total of 73 patients (78.5%) had an uneventful recovery. Conclusion: The technique is reproducible with a low complication rate. While further studies are needed to confirm equivalency, early efforts suggest that TOETVA is not inferior to traditional open thyroidectomy in appropriately selected patients.

RESUMO Objetivo: Investigar a associação entre o envelhecimento e os aspectos funcionais da deglutição (penetração laríngea e aspiração laringotraqueal) em indivíduos submetidos à laringectomia supracricóidea no período tardio e sem queixas. Métodos: Setenta pacientes, sendo 56 (80%) >60 anos e 14 (20%) <60 anos, em acompanhamento ambulatorial, após tratamento oncológico e sem queixas de deglutição, realizaram avaliação funcional por meio da videofluoroscopia da deglutição. A classificação das imagens foi realizada por meio da escala de penetração-aspiração desenvolvida por Rosenbek. O teste do χ2 e a regressão logística foram aplicados para associação das categorias de idade aos desfechos (penetração e aspiração). Resultados: Os pacientes com idade acima de 60 anos apresentaram maior prevalência de penetração (24,29%) e aspiração (48,57%) do que aqueles com idade inferior a 60 anos. Nesta amostra, a aspiração se mostrou associada à idade. Pacientes acima de 60 anos tiveram chance 27% maior de penetração durante a deglutição do que os com menos de 60 anos. Pacientes acima de 60 anos tiveram chance aproximadamente quatro vezes maior de aspiração laringotraqueal do que pacientes com menos de 60 anos. Conclusão: Em pacientes sem queixas de deglutição no pós-operatório tardio de laringectomia supracricóidea, há maior chance de aspiração laringotraqueal em idosos acima de 60 anos do que em indivíduos abaixo de 60 anos.

ABSTRACT: Objective: To investigate the association between aging and the functional aspects of swallowing (laryngeal penetration and laryngotracheal aspiration) in individuals who underwent supracricoid laryngectomy in the late period and without complaints. Methods: A total of 70 patients, 56 (80%) aged >60 years and 14 (20%) <60 years, under outpatient follow-up, after cancer treatment and with no complaints of swallowing, performed functional evaluation using the swallowing videofluoroscopy. Image classification was performed using the penetration-aspiration scale developed by Rosenbek. The χ2 test and logistic regression were applied to associate the age categories to the outcomes (penetration and aspiration). Results: Patients aged over 60 years had a higher prevalence of penetration (24.29%) and aspiration (48.57%) than patients aged under 60 years. In this sample, aspiration was associated with age. Patients aged over 60 years were more likely to present penetration (27% more) during swallowing than patients under 60 years. Patients aged over 60 years had an approximately four-fold greater probability of laryngotracheal aspiration than patients aged under 60 years. Conclusion: In patients without complaints of swallowing in the late postoperative period of supracricoid laryngectomy, there is a greater probability of laryngotracheal aspiration in elderly aged over 60 years than in individuals under 60 years.

RESUMO Em tumores transglóticos estendidos para base de língua, a indicação para ressecção do osso hioide descarta a possibilidade de realização de uma laringectomia parcial horizontal clássica, devido ao grande risco de complicações pulmonares oriundas de uma disfagia grave. O objetivo deste estudo foi descrever os aspectos funcionais de deglutição e voz de um paciente submetido à laringectomia supratraqueal ampliada com cricoglossohioidopexia. Trata-se de um homem de 69 anos, com tumoração transglótica na hemilaringe direita, submetido à laringectomia supratraqueal ampliada, com ampliação para base de língua, osso hioide e aritenoide direita. Na videofluoroscopia da deglutição, observou-se aspiração silente para líquido fino durante a deglutição e resíduo em base de língua, valécula, aritenoide, esfíncter esofágico superior e recessos piriformes em todas as consistências e volumes. Na videolaringoscopia, observou-se voz por meio da vibração da unidade cricoaritenóidea esquerda, associada à base de língua e constritores da faringe. No protocolo Consensus Auditory-Perceptual Evaluation of Voice (CAPE V), notou-se grau moderado de rouquidão e soprosidade. O paciente apresentou preservação parcial das funções laríngeas, grau moderado de disfonia e alimentação e hidratação exclusivas por via oral, com sólidos macios e líquido espessado em néctar, sem prejuízos à saúde pulmonar, até o momento.

ABSTRACT In transglottic tumors extended to the base of the tongue, the indication for resection of the hyoid bone rules out the possibility of performing a classic horizontal partial laryngectomy due to the high risk of pulmonary complications resulting from severe dysphagia. This study aims to describe the functional aspects of swallowing and voice of a patient undergoing an enlarged supratracheal laryngectomy with cricoglossohioidopexy. This is a 69-year-old man with a transglottic tumor in the right hemilarynx, who underwent an extended supratracheal laryngectomy with enlargement to the base of the tongue, hyoid bone and right arytenoid. In swallowing videofluoroscopy, silent aspiration was observed in fine liquid and residue on the basis of tongue, valecule, arytenoid, upper esophageal sphincter and pyriform recesses in all consistencies and volumes. In videolaryngoscopy, a voice was observed through the vibration of the left cricoarytenoid unit associated with the base of the tongue and constrictors of the pharynx. The Consensus Auditory-Perceptual Evaluation of Voice (CAPE V) showed a moderate degree of hoarseness and breathiness. The patient had partial preservation of laryngeal functions, with a moderate degree of dysphonia and exclusive oral feeding and hydration with soft solids and thickened liquid in nectar without impairing lung health until the study.

RESUMO Objetivo Descrever os resultados funcionais e de qualidade de vida após a laringectomia supratraqueal alargada. Métodos No período de setembro de 2009 a janeiro de 2018, 11 indivíduos do sexo masculino foram submetidos à laringectomia supratraqueal alargada. As habilidades de deglutição foram avaliadas por meio da videofluoroscopia e da escala clínica Functional Communication Measures . As vozes foram classificadas por análise perceptivo-auditiva da Consensus Auditory-Perceptual Evaluation of Voice . Todos os voluntários preencheram um questionário de autoavaliação para voz e deglutição. Resultados A aspiração foi encontrada em quatro pacientes, e todos apresentaram estase em diferentes estruturas. Todos os sujeitos deste estudo apresentavam alimentação e hidratação exclusivas por via oral. Na avaliação da qualidade de vida na deglutição, os pacientes demonstraram médias >80 em todas as áreas (83,47 média dos escores). O grau geral e a presença de rugosidade foram os maiores escores médios na avaliação perceptivo-auditiva da voz (37,81 e 49,36 consecutivamente). A média de 33,36 (±22,56) demonstrou pouco impacto na qualidade de vida sob a perspectiva dos aspectos vocais. Conclusão Após a laringectomia supratraqueal, a deglutição foi suficientemente restaurada, e a qualidade de vida foi satisfatória. A voz apresenta qualidade gravemente comprometida com comunicação oral preservada, demonstrando baixo impacto nas atividades da vida diária. Todos os indivíduos que mantiveram duas unidades cricoaritenóideas apresentaram melhores resultados funcionais na deglutição e na voz.

ABSTRACT Objective To describe functional and quality of life results after extended supratracheal laryngectomy. Methods In the period from September 2009 to January 2018, 11 male subjects were submitted to extended supratracheal laryngectomy. Swallowing abilities were assessed through videofluoroscopy and the clinical scale Functional Communication Measures of Swallowing. The voices were classified by means of the perceptual-auditory analysis Consensus Auditory-Perceptual Evaluation of Voice. All subjects completed a self-assessment questionnaire for voice and swallowing. Results Aspiration was found in four patients and all presented stasis in different structures. All subjects in this study were exclusively orally fed and hydrated. In the evaluation of quality of life in swallowing, patients had mean >80 in all areas (83.47 mean of scores). The general degree and the presence of roughness were the highest means present in Consensus Auditory-Perceptual Evaluation of Voice (37.81 and 49.36, respectively). The mean of 33.36 (±22.56) had little impact on quality of life under the perspective of vocal aspects. Conclusion After supratracheal laryngectomy, swallowing was sufficiently restored and the quality of life was satisfactory. The voice presents severely impaired quality and preserved oral communication, with low impact on the activities of daily living. All individuals who maintained two cricoarytenoid units presented better functional results in swallowing and voice.

RESUMO A lesão do nervo facial é a principal complicação neurológica relacionada às parotidectomias e, em geral, o ramo marginal mandibular é o mais frequentemente acometido. Objetivo Testar um Sistema Sunnybrook de Graduação Facial modificado (mS-FGS) como uma nova ferramenta para avaliar a função do nervo facial após a parotidectomia, enfatizando o ramo marginal mandibular. Métodos Estudo retrospectivo, baseado em prontuários de 73 casos (40 do sexo feminino, 18-84 anos, idade média = 53,2), submetidos à parotidectomia, com preservação do nervo facial. Todos os pacientes apresentavam neoplasias parotídeas ou câncer de pele avançado, e foram tratados pela autora principal entre 2006 e 2014. Resultados Neste estudo, os músculos inervados pelo ramo marginal mandibular foram os mais acometidos (72,6% dos casos), principalmente nos pacientes que realizaram esvaziamento cervical (p = 0,023). Os Escores de Movimento Voluntário obtidos pelo sistema modificado foram inferiores aos obtidos pelo original (p < 0,001). As melhores pontuações foram observadas em pacientes com tumores benignos parotídeos e os piores resultados, naqueles com câncer de pele. Pacientes que necessitaram de esvaziamento cervical e ressecção de outras estruturas, além da parótida, apresentaram escores menores (p = 0,031 e p = 0,021), evidenciados apenas pelo sistema modificado. Os tumores malignos geraram escores significativamente menores, independentemente do instrumento empregado. A análise pós fisioterapia envolveu 50 casos. Os piores resultados, após a intervenção fisioterapêutica, também foram observados nos músculos inervados pelo ramo marginal mandibular. Conclusão A avaliação da disfunção facial pós-parotidectomia, através do Sistema Sunnybrook com a modificação proposta permitiu uma apreciação mais detalhada do ramo marginal mandibular, sem prejuízo à avaliação dos demais ramos.

ABSTRACT Facial nerve injury, affecting mainly the marginal mandibular branch, is the most frequent neurologic complication from parotidectomy. Objective To test a modified Sunnybrook Facial Grading System as a new tool to assess the facial nerve function following parotidectomy, emphasizing the marginal mandibular branch. Methods We reviewed the medical records of 73 post-parotidectomy patients (40 female, 18-84 years old, mean age 53.2 years) with facial nerve sparing, referred to the Department of Physical Therapy. All patients had parotid neoplasms or advanced skin cancer, and were followed by the principal author between 2006 and 2014. Results The muscles innervated by the marginal mandibular branch were the most frequently affected (72.6%), particularly in patients undergoing neck dissection (p = 0.023). The voluntary movement scores obtained with the modified system were significantly lower compared with the original version (p < 0.001). The best and worst scores were observed in patients with benign parotid tumors and skin cancer, respectively. Patients requiring neck dissection (p = 0.031) and resection of other structures (p = 0.021) had the lowest scores, evidenced only with the modified version. Patients with malignant tumors had significantly worse ratings, regardless of the Sunnybrook system version. The post-physiotherapy analysis involved 50 patients. The worst facial rehabilitation outcomes were related to the marginal mandibular branch function. Conclusion The modified Sunnybrook Facial Grading System improved the marginal mandibular branch assessment, preserving the evaluation of other facial nerve branches.

OBJETIVOS: Com a intenção de se avaliar os resultados funcionais e terapêuticos da laringectomia supracricóide com crico-hióide-epiglote-pexia (CHEP) foram estudados 50 casos de pacientes com carcinoma epidermóide da glote classificados como T2/T3 submetidos a esta técnica em nossa instituição. MÉTODOS: Foi realizada uma análise retrospectiva entre 1996 e 1999. Classificamos 18 pacientes como T2N0M0 e 32 pacientes como T3N0M0. Quarenta e um pacientes foram submetidos a esvaziamento cervical seletivo lateral bilateralmente, quatro foram submetidos ao mesmo esvaziamento unilateralmente, e cinco não foram esvaziados. Analisamos as complicações e a sobrevida livre de doença pelo método de Kaplan-Meyer. RESULTADOS: Dez pacientes tiveram complicações pós-operatórias, dois foram tratados com complementação da laringectomia. Os 48 pacientes restantes mantiveram a via aérea normal, deglutição e a voz. Três pacientes no grupo submetido a esvaziamento cervical apresentaram linfonodo metastático. Quatro pacientes tiveram recidiva da doença, três com recidiva local, sendo dois tratados com laringectomia total e estão vivos e sem doença, o outro com doença avançada alcançou o óbito pela doença. O paciente que teve recidiva no pescoço foi tratado com esvaziamento cervical mais radioterapia e morreu com doença. Dois pacientes tiveram um segundo tumor primário em orofaringe, sendo um tratado com radioterapia paliativa e morreu com doença e o outro tratado com cirurgia está vivo e sem doença. A sobrevida livre de doença em três anos foi de 88% para pacientes T2 e 72% para pacientes T3. CONCLUSÕES: Esta técnica é útil no tratamento de casos selecionados de carcinoma epidermóide da glote T2/T3 sempre se considerando a extensão da doença. A incidência de complicações necessitando laringectomia total de resgate não compromete a funcionalidade desta técnica. A sobrevivência é comparável aos pacientes submetidos a laringectomia total e laringectomia "near-total".

BACKGROUND: Our objective was to assess whether Supracricoid Laryngectomy with CricoHiodoEpiglottoPexy (CHEP) could successfully achive cure preserving voice in the treatment of glottic laryngeal cancer. METHODS: A retrospective analysis has been carried out between 1996 through 1999. We classified 18 patients as T2N0M0 and 32 patients as T3N0M0. Fourty one patients underwent selective bilateral lateral neck dissection, four had unilateral neck dissection and five patients had the neck undissected. Survival was analyzed under the Kaplan-Meyer method. RESULTS: Ten patients had postoperative complications, two treated with total laryngectomy. The remained 48 patients maintained normal airway, swallowing and speech. Three patients in the neck dissection group presented occult neck metastasis. Four patients had recurrences, three of them were local. Two patients treated with total laryngectomy are alive without disease, and another had advanced recurrence and died. One patient had neck recurrence and was treated with radical neck dissection plus radiotherapy and died from the disease. Two patients presented a second tumor in the oropharynx. One of them was treated with palliative radiotherapy and died and the other had surgical resection and is alive without disease. Three years disease free survival was 88% for T2 and 72% for T3. CONCLUSIONS: This technique is useful in the treatment of selected cases of T3/T2 glottic cancer, regarding the extension of the disease. The incidence of complications required completion laryngectomy which did not compromise the functionality of this technique. Survival is comparable to patients submitted to total laryngectomy and near-total laryngectomy, regarding the extension of the lesion.
