Summary
Laryngeal tuberculosis, a rare form of extrapulmonary tuberculosis, affects the voice box. This study found that most patients with laryngeal tuberculosis also had pulmonary tuberculosis and responded well to medical treatment.
Area of Science:
- Otolaryngology
- Infectious Diseases
- Pulmonology
Context:
- Laryngeal tuberculosis is an uncommon manifestation of Mycobacterium tuberculosis infection.
- This retrospective case series analyzes patients diagnosed with laryngeal tuberculosis between 1990 and 2000.
Purpose:
- To describe the clinical characteristics, diagnosis, and treatment outcomes of laryngeal tuberculosis.
- To highlight the association between laryngeal and pulmonary tuberculosis.
Summary:
- Eleven patients with laryngeal tuberculosis were identified.
- Common symptoms included dysphonia and dysphagia.
- Eight patients (73%) had associated pulmonary tuberculosis, and Mycobacterium tuberculosis was isolated from sputum in seven patients.
- Laryngeal biopsy confirmed granulomatous laryngitis in all eight biopsied patients.
- All patients showed favorable outcomes with medical treatment.
Impact:
- This study underscores the importance of considering laryngeal tuberculosis in patients with persistent hoarseness and/or difficulty swallowing, especially those with known or suspected pulmonary tuberculosis.
- Early diagnosis and appropriate medical management lead to favorable treatment responses.
