Abstract: Objective: To analyze the clinical data of 199 patients with tuberculous lymphadenitis in maxillofacial and cervical region. Methods: The clinical data of 199 patients confirmed by pathological examination in our hospital from 2010 to the end of 2019 were retrospective analyzed. Results: There were 62 males and 137 females. Forty-five patients had obvious pain and discomfort. Only three patients had tuberculosis history. Most of the cases were multiple enlarged lymphonodus with different sizes. The distribution frequency of enlarged lymphonodus in the maxillofacial and cervical region were Ⅴ>Ⅱ>Ⅰ> parotid region >Ⅵ>Ⅲ>Ⅳ. CT diagnosis included 47 cases of tuberculosis, 17 cases of malignant tumors, 19 cases of infectious diseases, and 48 cases of uncertain. Chest X-ray examination showed tuberculosis of lung or pleura in 31 cases. The relevance rate of caseous necrosis between early and last five years pathological specimen was obviously different (P<0.05). There were 36 positive patients out of 45 patients with T-SPOT examination. Conclusion: Tuberculous lymphadenitis in maxillofacial and cervical region is the most common extrapulmonary tuberculosis. It is necessary to strengthen the prevention of young people. CT enhanced scan and T-SPOT examination had higher diagnostic value than other examinations.
