Preliminary study on endoscope-assisted resection of superficial benign tumor of parotid gland

Abstract

Objective: To summarize the preliminary experience of endoscope -assisted resection of superficial parotid gland benign tumors, and to discuss the indications, advantages and disadvantages of the operation. Methods: The clinical data of 18 patients who underwent extracapsular resection of superficial parotid gland benign tumor in Department of Oral and Maxillofacial Surgery, Qilu Hospital of Shandong University from March 2018 to March 2019 were retrospectively analyzed, and the surgical methods were introduced. The indications, long axis length of tumor, incision design, operation time, intraoperative blood loss, postoperative drainage and drainage time, aesthetic satisfaction, postoperative complications and follow-up time were counted. Results: All procedures were completed as expected. The length of the long axis of the tumor was (2.3±0.6) cm, the incision in the tragus around the earlobe was short and concealed, the incision length was (5.1±1.3) cm, the operation duration was (2.0±0.4) h, intraoperative blood loss was (168.9±18.8) ml, postoperative drainage was (29.5±11.7) ml, drainage time was (3.6±0.5) d, 2 cases of temporary facial paralysis or earlobe numbness, three months after the operation, the results of the visual analogue scale of the incision design and the aesthetic effect were (9.6±0.1). Conclusions: Endoscope-assisted resection of superficial parotid gland benign tumor by inner tragus around earlobe approach is applicable and reliable, can reduce complications, shorten surgical incision to obtain satisfactory aesthetic effect, which is worth further expansion and improvement.
