Abstract: Objective To analyze the clinical characteristics and diagnostic points of 18 patients with laryngeal tuberculosis. Methods The clinical data of 18 patients with laryngeal tuberculosis were retrospectively analyzed in Tianjin First Center Hospital. Results The major manifestations of laryngeal tuberculosis include hoarseness, sore throat, foreign body sensation in the throat, dysphagia, hemoptysis and cough, but the general symptoms were not obvious. The throat was characterized by pale swelling, proliferative nodules, and ulcerative erosion. According to the results of chest computed tomography(CT)or X radiography, 10 patients had pulmonary tuberculosis, but did not receive anti-tuberculosis treatment. One of 9 patients undergoing sputum smear acid-fast staining was shown positive. Through pathological examination, 6 out of 14 patients were found gram-positive bacteria, and the positive rate was 42.9%. There was 1 patient with laryngeal tuberculosis and laryngocarcinoma after all the diagnosed patients were given anti-tuberculosis treatment in Tuberculosis Dispensary. Conclusion Laryngeal tuberculosis is closely related to lung tuberculosis, and is easily caused by the respiratory tract of patients with pulmonary tuberculosis in Tianjin. Laryngeal tuberculosis tends to be missed diagnosis and misdiagnosed due to atypical general symptoms. Pathological biopsy under the fibrolaryngoscope or general anesthesia should be taken as a major method to make the accurate diagnosis.
