Epidemiological considerations and clincial features of ENT tuberculosis

Between 1 April 1996 and 30 June 1997, 1003 ear, nose and throat (ENT) outpatients and 340 inpatients diagnosed as having pulmonary tuberculosis were analysed for ENT manifestations of tuberculosis to determine the relationship to sputum positivity, whether any high risk factors exist for the ENT manifestations as compared to other pulmonary tuberculosis patients, and the response to anti-tubercular treatment. The commonest ENT manifestation was found to be laryngitis (seven cases), which was more common in pulmonary tuberculosis patients (five out of seven), all except one of whom were sputum negative. All of these patients were defaulters from anti-tuberculosis treatment or relapse cases, and vocal cords were the commonest site of involvement. One case of tuberculous tonsillitis and one case of tuberculous mastoiditis were also noted. The practical implications of an awareness of ENT tuberculosis is a benefit of anti-tubercular therapy and hence conservative management usually suffices.
