Abstract: Objective To investigate the efficacy of modified cervical-parotid approach in resection of upper benign tumors in the parapharyngeal space. Methods A total of 7 patients were enrolled. Preoperative imaging showed big-sized, dumbbell-shaped tumors with unclear boundary. The modified cervical-parotid approach was adopted. After the main trunk and temporal branch of the facial nerves were identified, the upper part of the tumors was separated through the anterior cartilage of the external auditory canal, the posterior margin of parotid gland and the upper part of temporal branch. The tumors were then isolated and removed from the submaxillary region. During the procedure, the superficial lobe of the parotid gland was preserved, and only the necessary facial nerve branches were dissected. Results All tumors were completely removed in one stage operation. Postoperative pathology showed pleomorphic adenoma in 6 cases and schwannoma in 1 case. The hemorrhage volume was less than 300 mL. Mild peripheral facial paralysis occurred in 1 patient, who returned normal 14 days later. All patients had satisfactory cosmetic outcomes. Conclusion The modified cervical-parotid approach can remove the tumors safely and completely, reduce the exposure of facial nerves and superficial lobe of the parotid gland, and reduce the incidence of postoperative neuropathic complications and parotid pitting changes.
