Abstract
The early history of tracheostomy and intubation suggested that upper airway obstruction had been in existence for a long time. A study of 80 patients with upper airway obstructions treated over a 10-year period between 1990 and 1999 was carried out to determine the aetiology and incidence. There were 65 (81%) males and 15 (19%) females with a sex ratio of 4.3:1 (M:F). The age ranged from 6 months to 70 years; with mean age of 27 years. Ninety-nine per cent were acquired causes and 1% were congenital. The commonest site of obstruction was in the larynx 81%. In children, the most common causes were laryngeal papilloma (16%) and foreign body (14%), while in adults, laryngeal carcinoma (24%) and direct laryngeal injuries (15%). The study revealed a wide range of causes of upper respiratory tract obstruction encountered in a developing tropical country. Health education and community awareness programmes should be supported. This would encourage early presentation, prompt referral to experts and earlier treatment with improved outcome.
