Abstract
Despite the availability of various surgical options, management of laryngotracheal stenosis (LTS) still remains an enigma. Proper selection of surgical technique in each clinical setting is the key for successful outcome. The purpose of this article is to guide one in selection of appropriate surgical procedures depending upon various stenosis parameters. Aim To record the clinical profile of cases with LTS. To assess the outcome following various surgical interventions based on site, severity, cause of stenosis and to derive conclusions regarding treatment options in various stenosis. Materials and Methods It is a study of 60 cases with chronic LTS. It includes retrospective study of 30 cases treated from 2004 and prospective study of 30 cases from Jan 2007 to Dec 2009. A total of 60 cases with LTS were enrolled in the study. Patients were assessed clinically by eliciting detailed history and analyzing previous records. After assessment of extent of stenosis, they were subjected to surgical interventions (endoscopic/open approach). Outcome after surgical interventions was assessed. Results 60 patients were included in the study, in the age group of 2.5–50 years. There were 46 (77%) male patients and 14 (23%) female patients. Intrinsic trauma, secondary to prolonged intubation was the most common cause of LTS, seen in 23 (38%) cases followed by post traumatic stenosis (strangulation-18 (30%), blunt injury-15 (25%), penetrating neck injury-4 (7%)). Stenosis was divided into 6 types based on subsite involvement. Of which, cervical trachea was the commonest site of involvement (25/60 cases). Majority of cases had fixed vocal cords at presentation (55%), more commonly due to post traumatic injury. 60 cases had undergone a total of 110 surgical procedures (endoscopic-56,open approach-54). In the end, overall decannulation rate is 93.3%. In site wise tracheal stenosis, isolated subglottis, combined glottis and subglottic stenosis had decannulation rate of 100% each and with mobile vocal cords, the success rate is 96%. Conclusions Post traumatic stenosis with fixed vocal cords is more common in our practice. Categorizing stenosis into various subtypes helps in treatment planning and predicts surgical outcome. Tracheal or subglottic stenosis with mobile vocal cords has better success rate.
