ABSTRACT
Abstract Introduction: Congenital laryngeal webs are rare, may be associated with other airway abnormalities and be one of many features of microdeletion 22q11. Meticulous evaluation is imperative when deciding which surgical technique to use. The choice of appropriate stenting may be decisive to avoid persistent anterior commissure synechia and poor voice results. Objective: To report outcomes for endoscopic and open surgical approaches in the treatment of congenital laryngeal webs and the challenges one may encounter while applying the current classification and deciding for the best treatment option. Methods: Retrospective review of medical and surgical charts for congenital laryngeal webs treated in two tertiary university centers. Results: Seven patients were included; following Cohen's classification there were: three type II webs, one of them with an atypical posterior synechia, two type III webs and two type IV webs. Six patients were submitted to laryngotracheal reconstruction and one was treated with an endoscopic approach. Description of precise glottic and subglottic involvement and tailored surgical options are presented. The LT mold® stent was used for long-term stenting that varied between 40 to 60 days. All patients were successfully decannulated with good voice quality and after follow-up of over one year, there were no complications associated with the surgeries. Conclusion: Congenital laryngeal webs should be suspected and thoroughly evaluated in the presence of neonatal dysphonia and early onset of laryngitis. Otolaryngologists must be familiar with associated lesions and genetic conditions that may be associated to congenital laryngeal webs. Congenital laryngeal webs may be successfully treated at an early age. The correct choice of surgical technique after meticulous evaluation of glottic and subglottic components of the web, presence of concomitant lesions and appropriate stenting, is imperative to avoid persistent scarring and poor voice quality.
Resumo Introdução: As membranas laríngeas congênitas são raras, podem estar associadas a outras anormalidades das vias aéreas e ser uma das muitas características da microdeleção 22q11. A avaliação cuidadosa é imprescindível na decisão de qual técnica cirúrgica deve ser usada. A escolha do stent apropriado pode ser decisiva para evitar sinéquia persistente da comissura anterior e maus resultados vocais. Objetivo: Relatar os resultados das abordagens cirúrgicas abertas e endoscópicas no tratamento das membranas laríngeas congênitas e os desafios que podem ser encontrados ao aplicar a classificação atual e decidir a melhor opção de tratamento. Método: Revisão retrospectiva de prontuários médicos e cirúrgicos de membranas laríngeas congênitas tratadas em dois centros universitários terciários. Resultados: Sete pacientes foram incluídos, de acordo com a classificação de Cohen: três membranas do tipo II, uma delas com sinéquia posterior atípica, duas membranas do tipo III e duas membranas do tipo IV. Seis pacientes foram submetidos à reconstrução laringotraqueal e um foi tratado por abordagem endoscópica. Descrição precisa do envolvimento glótico e subglótico e opções cirúrgicas personalizadas são apresentadas. O stent utilizado foi o LT mold® e o período variou entre 40 e 60 dias. Todos os pacientes foram decanulados com boa qualidade de voz e o seguimento foi superior a um ano, não houve complicações associadas às cirurgias. Conclusão: As membranas laríngeas congênitas devem ser suspeitadas e avaliadas minuciosamente na presença de disfonia neonatal e laringite de início precoce. Os otorrinolaringologistas devem estar familiarizados com lesões associadas e condições genéticas que podem estar associadas a membranas laríngeas congênitas. As membranas laríngeas congênitas são tratadas com sucesso em idades precoces. A escolha da técnica cirúrgica após avaliação meticulosa dos componentes glóticos e subglóticos da membrana, presença de lesões concomitantes e uso do stent adequado é imprescindível para evitar cicatrizes persistentes e má qualidade da voz.
ABSTRACT
Background: Conditions causing stridor in paediatric patients can range from minor illnesses to life-threatening disorders. Proper evaluation and correct diagnosis are essential for timely intervention. The objective of this study was to determine the aetiological profiles and the management of paediatric patients with stridor referred to the Otorhinolaryngology Department of Hospital Serdang. Methods: Medical records of all paediatric patients presenting with symptom of stridor from January 2010 to February 2015 were reviewed retrospectively. The patients’ demographic data, clinical notes, laryngoscope findings, diagnosis and management were retrieved and analysed. Results: Out of the total 137 patients referred for noisy breathing, 121 patients had stridor and were included in this study. There were 73 males and 48 females—most were of Malay ethnicity (77.7%). The age of presentation ranged from newborn to 10 years, with a mean of 4.9 months. Eighteen patients (14.9%) had associated congenital pathologies. The majority were congenital causes (90.9%), in which laryngomalacia was the commonest (78.5%), followed by subglottic stenosis (5.0%), vallecular cyst (2.5%) and congenital vocal fold paralysis (2.5%). Twelve patients (9.9%) had synchronous airway lesion. The majority of the patients were managed conservatively. Thirty-one patients (25.6%) required surgical intervention, of which only one needed tracheostomy. Conclusion: Laryngomalacia was the commonest cause of stridor among paediatric patients. A synchronous airway lesion should be considered if the child has persistent or severe symptoms. The majority of the patients were managed conservatively.
