RESUMO
Introdução: O tratamento cirúrgico atual das estenoses laringotraqueais pediátricas inclui uma ampla variedade de procedimentos cirúrgicos, desde abordagem endoscópica até procedimentos mais extensos, como a reconstrução laringotraqueal e a ressecção cricotraqueal. Objetivo: Discutir as indicações e comparar as diferentes abordagens das estenoses laringotraqueais. Métodos: Foi realizado estudo retrospectivo demonstrando a experiência deste serviço no período de 1980 a 2008, no qual 49 casos foram tratados de acordo com grau e a localização da estenose. Trinta e dois casos foram submetidos à cirurgia endoscópica, 12 casos submetidos à reconstrução laringotraqueal, três casos de ressecção cricotraqueal e dois casos de rotary door flap. Resultados: Casos de estenose grau I e II apresentam bons resultados após cirurgia endoscópica enquanto casos grau III e IV necessitam de procedimentos externos. Na maioria dos casos foi necessária combinação de duas ou mais técnicas para obtenção dos resultados esperados.
Introduction: Nowadays, the surgical treatment of pediatric stenosis includes a variety of surgical procedures, from endoscopic approaches to more extensive procedures, such as laryngotracheal reconstruction and cricotracheal resection. Objective: To discuss the surgical indications and to compare the different approaches of laryngotracheal stenosis. Methods: A retrospective study was performed to demonstrate the experience of this institution from 1980 to 2008, in which 49 patients were treated according to the grade and site of the stenosis. Thirty-two patients underwent endoscopic surgery, 12 laryngotracheal reconstructions, 3 cricotracheal resections and 2 rotary door flaps. Results: Grade I and mild grade II stenosis had good results with endoscopic surgery, whereas more severe stenosis - grade II, grade III and IV - required more extensive procedures. In most patients, more than 2 procedures within the several types above related were necessary to reach the expected success.
RESUMO
OBJECTIVES: To obtain complete glottal closure, and evaluate improvement of vocal fold vibration amplitude and vocal quality in patients with sulcus vocalis. METHODS: Autogenous fat and/or fascia augmentation was used in 34 patients with sulcus vocalis. Mean follow-up time was 1 year. The perceptual acoustic and phonatory functions and videolaryngostroboscopic data were evaluated before and after the procedure. RESULTS: Most of the individuals reported an improvement of vocal quality, a complete glottal closure, an enhancement of mucosal wave excursion, and significant results of acoustic perceptual and phonatory functions after the surgery. CONCLUSION: Fat and fascia injections are effective autogenous implants and should be considered options in the treatment of patients with sulcus vocalis and vocal fold atrophy.
