Incidence, Diagnosis and Treatment of Otorhinolaryngological, Head and Neck Tuberculosis: A Prospective Clinical Study.

Tuberculosis is a disease of diversified presentation. It affects almost all organs in the body, and otorhinolaryngological, head and neck involvement is not an exception.  To increase awareness about the different clinical presentations of otorhinolaryngological, head and neck tuberculosis, the techniques employed to diagnose it, and to assess the response to the treatment.  We conducted a prospective study of 114 patients who presented primarily with otorhinolaryngological, head and neck tuberculosis. Routine blood investigations, chest radiographs, the tuberculin test, and sputum examination for the presence of acid-fast bacilli were performed in all cases. Site-specific investigations were performed in relevant cases only. The patients were treated according to the antitubercular treatment (ATT) regimen recommended by the Indian Ministry of Health and Family Welfare's National Tuberculosis Elimination Program (NTEP), and they were followed up clinically two and six months after starting the ATT.  Tubercular cervical lymphadenopathy was the most common clinical presentation (85.96%), followed by deep neck abscess (5.27%). Fine-needle aspiration cytology proved to be a reliable tool for the diagnosis of tubercular lymphadenopathy. Improvement at the end of 2 and 6 months of the ATT was observed in 90.35% and 96.50% of the cases respectively.  The diagnosis of otorhinolaryngological, head and neck tuberculosis requires a high index of clinical suspicion, and the ATT proved to be very effective in reducing the severity of the disease.
