[Tuberculosis of the otorhinolaryngologic region: laryngeal and extra-laryngeal forms]

The aim of the study was to assess all patients with ENT symptoms whose histologic and/or microbiologic diagnosis confirmed tuberculosis.

All the anatomopathologic studies performed in the ENT unit in the authors' hospital in which the presence of acid-alcohol resistant bacilli were observed. All cases of cervical adenitis were not included.

Eighteen patients with the following localizations were studied: 14 laryngeal tuberculosis and 4 extra-laryngeal tuberculosis (2 oropharyngeal, 1 otic and 1 sinusal). In the laryngeal forms, all patients were male except for one, and all were smokers. The duration of the symptoms was greater than 3 months in all the cases. Unilateral cord involvement was most commonly found, and in 2 cases this was associated with carcinoma of the vocal cord. Twenty-nine percent did not present with coincident pulmonary tuberculosis. None of the extra-laryngeal forms showed pulmonary involvement. All the patients were women and only 1 was smoker, the symptomatology was greater than 3 months in all cases and all required biopsy for achieving diagnosis. The evolution with medical treatment was favorable in all cases. During the same time period, 2300 cases of pulmonary tuberculosis were diagnosed in the authors' hospital.

Tuberculosis of the upper respiratory tract is infrequent. Pulmonary involvement is common, although in this series this was only found in 71% of all laryngeal forms. Diagnosis is difficult, except in cases of coinciding pulmonary involvement and usually requires surgery for biopsy. Response to medical treatment is usually good.
