Subglottic stenosis secondary to tuberculosis

Although the incidence of laryngeal tuberculosis has been declining over the past 30 years, it should still be considered in the differential diagnosis of patients with laryngeal pathology. In contrast to the pre-chemotherapy era, few, if any, signs of pulmonary tuberculosis are seen in such cases, and presentation is similar to either chronic non-specific laryngitis or carcinoma. The subglottis is a site rarely involved in laryngeal tuberculosis. Tissue biopsy and culture are diagnostic and a full course of antituberculous chemotherapy usually resolves the condition. Airway insufficiency due to fibrosis, however, often necessitates surgical intervention. We present a case where the only laryngeal manifestation of tuberculosis was subglottic stenosis.
