The incidence of postoperative facial palsy in 73 patients who had under-gone surgery for parotid gland tumor is reported. Slight facial palsy occurred in 9 (14%) of 66 benign tumors but recovered completely within 3 months following surgery. However, in 7 patients with malignant tumors, 3 (43%) developed permanent palsy and 1 (14%) temporary palsy. The incidence of benign tumors depends on the tumor size and localization. However, the incidence decreased considerably in the last 6 years compared to the first 6 years. This is considered to be due to routine use of computed tomography with sialography and microsurgery during parotidectomy.
报告了73例接受腮腺肿瘤手术患者的术后面瘫发生率。66例良性肿瘤患者中有9例（14%）出现轻度面瘫，但术后3个月内完全恢复。然而，7例恶性肿瘤患者中，3例（43%）出现永久性面瘫，1例（14%）出现暂时性面瘫。良性肿瘤的发生率取决于肿瘤大小和位置。然而，与前6年相比，最近6年的发生率大幅下降。这被认为是由于腮腺切除术中常规使用计算机断层扫描唾液造影术和显微手术所致。
