Our results confirm endoscopic endonasal dacryocystorhinostomy as an acceptable and safe method for treating children with nasolacrimal duct obstructions that are resistant to probings.
Objetivos: Epífora em pacientes nos quais a dacriocistografia mostra vias lacrimais permeáveis constitui ainda desafio ao especialista, especialmente quando não há lacrimejamento reflexo, nem alterações oculares externas, palpebrais ou de pontos lacrimais. Nestes pacientes, com provável obstrução incompleta, quisemos verificar o resultado da dacriocistorrinostomia endonasal endoscópica. Métodos: Doze pacientes com epífora e vias lacrimais permeáveis à dacriocistografia foram submetidos a dacriocistorrinostomia endonasal, utilizando-se a uncinectomia no meato médio. Resultados: Sete pacientes ficaram livres da epífora e três obtiveram melhora significativa após seguimento de 3 meses. Conclusão: A dacriocistorrinostomia endonasal é alternativa de tratamento válida para o tratamento de epífora em pacientes com vias lacrimais pérvias à dacriocistografia e sem alterações palpebrais.
In patients with epiphora, lax eyelids and patent lacrimal ducts, the tarsal strip procedure can significantly improve epiphora in most cases. As laxity ceased to exist in all eyelids, an assumption can be made that in some of the failures there may be other causes, concomitant with eyelid laxity, to explain perseverance of epiphora.
Aim:To verify whether our results with endonasal endoscopic dacryocystorhinostomy in children with nasolacrimal duct obstruction allow us to consider this technique a valid treatment alternative for children. Study design: clinical with transversal cohort. Material and Method: Twenty-seven endoscopic endonasal dacryocystorhinostomies were performed in children 2 to 12 years of age for nasolacrimal duct obstruction. Previous probings in all patients were unsuccessful. The technique employed uncinectomy and a small lacrimal sac opening. Follow-up time was 3 months. Results: Twenty-one surgeries (77,8%) were successful. The only complication was silicone prolapse in one case. Conclusion: Our results confirm endoscopic endonasal dacryocystorhinostomy as an acceptable and safe method for treating children with nasolacrimal duct obstructions that are resistant to probings.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
