内镜辅助下腮腺浅叶部分切除术与传统腮腺浅叶部分切除术的比较研究

Objective To investigate the feasibility of endoscopy-assisted partial-superficial parotidectomy. Methods 38 cases with benign tumors located in the superficial lobe of the parotid gland were randomly assigned to receive conventional (20 cases) or endoscopic (18 cases) partial-superficial paretidectomy. Two short incisions, which were 2 ～ 2.5 cm in length and located at retromandibular and postauricular area, were adopted for endoscopy-assisted surgery. The facial nerve was dissected through retrograde approach. Results The tumors were successfidly resected with endoscopy in 18 cases. The operation time was not significantly different between the conventional and endoscopy-assisted procedures (P > 0.05). The intraoperative blood loss was markedly lower in endoscopy-assisted group, compared with conventional group(P < 0.01). All the 18 cases with endoscopy-assisted surgery were satisfactory with the postoperative cosmetic results. The great auricular nerve was preserved very well in 12 patients(66.6%). Transcient facial paralysis happened in 1 ease and relieved 1 months later. Salivary fistula occurred in 1 case and recovered after dressing with pressure for 2 weeks. All the patients were followed up for 24 ～ 50 months (mean, 39 months) without relapse. Conclusions Endoscopy-assisted partial-superficial parotidectomy can successfully treat benign tumors located in the superficial lobe of parotid gland with a better postoperative cosmetic result.
