We retrospectively analyzed 125 patients of salivary gland tumor operated at Asan medical center from 1989 to 1996. The most commonly involved gland was parotid(69.6%) and the most frequent tumor was pleomorphic adenoma(56%). The proportion of the malignancy was 25.8% in parotid, 17.6% in submandibular gland, respectively. Facial palsy was developed postoperatively in 29 patients, however, seven patients were lost of follow up because five were died of disease and two were transferred to other hospitals. Persistent facial palsy were seven:four in the benign tumor, three in the malignant tumor. Transient facial palsy were 15:12 in the benign tumor, three in the malignant tumor. In the transient facial palsy, 10 patients were recovered within three months. Among 32 malignant tumor, the number of recurrence or distant metastasis were 12:four were distant metastasis alone, two were metastasis to the cervical lymph node, four were local recurrence alone and two were local recurrence with distant metastasis. The highest recurrence of the tumor was found in high grade-mucoepidermoid carcinoma(83.3%). Overall tumor recurrences were significantly related to positive cervical lymph node metastasis or positive resection margin:recurrence rate of the positive lymph node metastasis was 44.4%(four of nine) and the recurrence rate of positive resection margin was 50%(seven of 14).
