Superficial parotidectomy is an effective management for benign and malignant tumours of the superficial lobe of the parotid gland. Frey's syndrome is one of the most common complications observed after parotidectomy. The objective of our study was to find the incidence of Frey's syndrome 6 months and 1 year postoperatively after doing posterior belly of the digastric flap during superficial parotidectomy.
This is an observational prospective study done in the Department of General Surgery of the Institute from November 2018 to December 2020. Thirty-eight patients with parotid swellings (both due to benign or malignant causes) were evaluated preoperatively and planned for superficial parotidectomy with a posterior belly of digastric muscle (PBDM) flap to prevent the occurrence of Frey's syndrome. They were followed up in 6 months and 1 year. Minor's test was done in each visit to look for the occurrence of Frey's syndrome.
Two patients (5.2%) out of 38 patients developed asymptomatic Frey's syndrome after 6 months postoperatively out of which one patient (2.6%) developed symptomatic Frey's syndrome after 9 months postoperatively with symptoms such as sweating, flushing, and redness over the parotid area during chewing.
PBDM flap following superficial parotidectomy in a single-stage surgery is an effective and easy method to prevent Frey's syndrome. This procedure is easy to perform and requires no complex dissection. There have not been many studies regarding the use of this flap; hence, this study may be considered as a pilot study.
腮腺浅叶切除术是治疗腮腺浅叶良恶性肿瘤的有效方法。味觉出汗综合征是腮腺切除术后最常见的并发症之一。我们研究的目的是找出在腮腺浅叶切除术中采用二腹肌后腹瓣后6个月和1年时味觉出汗综合征的发生率。
这是一项于2018年11月至2020年12月在该研究所普通外科进行的观察性前瞻性研究。对38例腮腺肿大患者（包括良性或恶性病因）进行术前评估，并计划行腮腺浅叶切除术并采用二腹肌后腹（PBDM）瓣以预防味觉出汗综合征的发生。对他们进行6个月和1年的随访。每次随访时进行Minor试验以查找味觉出汗综合征的发生情况。
38例患者中有2例（5.2%）在术后6个月出现无症状的味觉出汗综合征，其中1例（2.6%）在术后9个月出现有症状的味觉出汗综合征，症状包括咀嚼时腮腺区域出汗、潮红和发红。
在一期手术中腮腺浅叶切除术后采用PBDM瓣是预防味觉出汗综合征的一种有效且简便的方法。该手术操作简便，无需复杂的解剖。关于该瓣的使用研究不多；因此，本研究可被视为一项初步研究。
