PURPOSE: To develop a new approach of endoscopic resection for @entity5 through a cosmetic retroauricular incision with a water sac establishing the operative space. MATERIALS AND METHODS: Fifty-eight @entity1 with benign parotid superficial @entity1313 were randomly assigned to an endoscopic (29 @entity1 ) or a conventional (29 @entity1 ) surgery group. The maximum diameter of the @entity5 was 6   cm. The subjective satisfaction scores with the incision scar, incision length, operative @entity548 volume, @entity260 , and recurrence rate were compared between the groups. RESULTS: All operations were successfully performed. The endoscopic incision length (4.3  0.5   cm), @entity548 volume (26.6  10.4   mL), and incidence of temporary facial paresis (6.9%) differed from the conventional surgery group (P<.05). The scars were almost invisible behind the ear. The mean @entity1 satisfaction score was 8.9  0.7 in the endoscopic surgery group and 6.7  1.8 in the conventional surgery group (P<.05). Otherwise, @entity8810 and salivary fistula incidences were 3.4% (1/29) and 3.4% (1/29), respectively, in the endoscopic surgery group, which was not significantly different from the conventional surgery group (P>.05). No @entity5 recurrence was found during the 3-72 months of follow-up. CONCLUSIONS: Endoscopic resection through a cosmetic retroauricular incision with a water sac establishing operative space is a feasible method for treatment of benign parotid superficial @entity1313 . Its main advantages are that the small and concealed operative scars improved the cosmetic results, and it provided a novel method for establishing the operation working space that could reduce the operative @entity130 .
