RESUMO Objetivo: Avaliar a via lacrimal excretora (VLE) pelo método cintilográfico e dacriocistográfico, comparando-os. Métodos: Foi realizado estudo retrospectivo de 34 pacientes (68 VLE) do Ambulatório de Vias Lacrimais - UNESP e que foram submetidos a Dacriocistografia (DCG) e Cintilografia lacrimal (CL). Resultados: Observou-se que 61,8% das VLE direitas e 55,9% das esquerdas estavam pérvias à DCG. 73,5% dos pacientes apresentavam sinais radiológicos sugestivos de hipertrofia de cornetos. A CL revelou ausência de obstrução em 29,4% à direita e 23,5% à esquerda. Portanto, 32,3% das obstruções só foram detectadas pela CL. Conclusões: Os autores concluem ser a CL exame importante para o diagnóstico de obstrução da VLE, principalmente nos portadores de obstrução funcional.

SUMMARY Purpose: To evaluate the excretory lacrimal pathways (ELP) by scintigraphy and dacryocystography, comparing both methods. Methods: We studied 34 patient 5 (68 lacrimal systems) from the Lacrimal Pathway Outpatient Clinic who were submitted to dacryocystography (DCG) and lacrimal scintigraphy (LS). Results: It was observed that 61.8% of right ELP and 55.9%o of left ELP investigated did not have obstruction by DCG. 73.5%o of these patients had radiological signs suggestive of cornetus hypertrophy. The LS showed no obstruction in 29.4%c of right ELP and 23.5% of left ELP. However, 32.3%c of the ELP obstructions were only detected by scintigraphic examination. Conclusion: The authors concluded LS to be an important examination for the diagnosis of obstruction of the lacrimal system, mainly in the carriers of functional obstruction.
