Abstract: Objective: To analyze the clinical data of 149 patients with tuberculous lymphadenitis in maxillofacial and cervical region treated with neck dissection. Methods: The clinical data of 149 patients treated with neck dissection in our hospital from 2010 to the end of 2019 were retrospectively analyzed. Results: There were 45 males and 104 females, with average age of 34.9 years. There were 40 cases in region Ⅰ, 45 cases in region Ⅱ, 24 cases in region Ⅲ, 14 cases in region Ⅳ, 36 cases in region Ⅴ, 5 cases in region Ⅵ, and 26 cases in parotid gland. Among the 105 patients who received preoperative enhanced CT examination, 76 were diagnosed as tuberculosis and 29 as other diseases. All 149 patients underwent general anesthesia, and 37 patients underwent rapid intraoperative freezing examination. Among them, 2 listed results were considered to be of uncertain nature, 3 cases of reactive hyperplasia, and 32 cases of granulomatous lesions. Negative pressure drainage was performed in 127 cases and skin drainage in 22 cases. Partial incision dehiscence occurred in 2 patients after operation, and the wound healed in the second stage after dressing change. The other patients all healed in the first stage. There was no obvious nerve injury after operation. All patients received systematic anti-tuberculosis treatment after operation. Conclusion: Functional neck dissection for tuberculosis is an effective surgical treatment method. Comprehensive preoperative assessment, selection of the best surgical method, and small incision and stratified anatomy, can ensure the postoperative cervical function and reduce postoperative complications.
