Facial nerve function after partial superficial parotidectomy: An 11-year review (1987-1997)

Permanent facial nerve dysfunction is a potential complication of every parotid surgery. Partial superficial parotidectomy, a conservative resectioning that requires neither dissection of the full facial nerve nor excision of the superficial lobe, produces lower rates of facial nerve dysfunction and soft tissue deformity than the traditional method. This report describes a single surgeon's experience with partial superficial parotidectomy from 1987 to 1997. Fifty-nine patients with mobile, benign, and low-grade malignant tumors, limited to the superficial lobe, underwent partial superficial parotidectomy with selective nerve dissection. Adequate margins were obtained, based on the premise that the tumor-to-nerve margin is often the true one. No patients had permanent nerve paralysis or paresis, and only 10 incurred transient facial nerve paresis. Age, histology, and sex were not significant factors in postoperative facial nerve function. No patients had recurrences.
