Abstract Introduction There is change in nasalance post endonasal surgery which is not permanent. Objectives The objective of this study is to evaluate the long-term nasalance changes following different types of endonasal surgeries. Methods We included in this study patients who underwent sinonasal surgery at the Otorhinolaryngology Department in Zagazig University Hospitals from February 2015 until March 2016. We divided the patients into two groups according to the surgeries they underwent: Group (A) was the FESS group and group (B), the septoturbinoplasty group.We checked nasalance using a nasometer before and after the sinonasal surgery. Results Nasalance increased at one month after the operation in both groups. However, it returned to nearly original levels within three months postoperatively. Conclusion FESS, septoplasty, and turbinate surgery may lead to hypernasal speech. This hypernasal speech can be a result of change in the shape and diameter of the resonating vocal tract. Hypernasal speech in these circumstances may be a temporary finding that can decrease with time. Surgeons should inform their patients about the possibility of hypernasality after such types of surgery, especially if they are professional voice users.

<sec><title>Introduction</title><p>Although medialization thyroplasty utilizing Gore-Tex (Gore and Associates, Newark, Delaware, United States) has been discussed in the literature, few reports have assessed voice quality afterward, and they did not use a full assessment protocol.</p></sec><sec><title>Objective</title><p> To assess the improvement in voice quality after medialization thyroplasty utilizing Gore-Tex in patients with glottic insufficiency of variable etiology.</p></sec><sec><title>Methods</title><p>Eleven patients with glottic insufficiency of different etiologies that failed compensation were operated by type 1 thyroplasty utilizing Gore-Tex. Pre- and postoperative (1 week, 3 months, and 6 months) voice assessment was done and statistical analysis was performed on the results.</p></sec><sec><title>Results</title><p>In all postoperative assessments, there was significant improvement in the grade of dysphonia (p < 0.004) and highly significant reduction in the size of glottic gap and prolongation of maximum phonation time (p < 0.0001). The difference in voice parameters in the early (1 week) and the late (3 and 6months) postoperative period was not significant. None of the patients developed stridor or shortness of breath necessitating tracheotomy, and there was no implant extrusion in any patient during the study period.</p></sec><sec><title>Conclusion</title><p>Gore-Tex medialization provides reliable results for both subjective and objective voice parameters. It leads to a satisfactory restoration of voice whatever the etiology of glottic incompetence is. This technique is relatively easy and does not lead to major complications. Further studies with larger number of patients andmore extended periods of follow-up are still required to assess the long-term results of the technique regarding voice quality and implant extrusion.</p></sec>
