To evaluate the electromyographic activity of the masseter, temporal, and buccinator muscles, as well as anxiety levels, aesthetic satisfaction, and quality of life following bichectomy.
Nine patients were included. Electromyography of the masseter, anterior temporal, and buccinator muscles was performed, along with assessment of the number of masticatory cycles and mastication time until swallowing. Anxiety levels (Generalized Anxiety Disorder-7), the impact of surgery on quality of life (Glasgow Benefit Inventory - GBI), and patient aesthetic satisfaction were evaluated using questionnaires. Assessments were conducted before surgery (T0), 60 days after surgery (T1), and 120 days after surgery (T2). A 2-way repeated measures ANOVA was used and when the analyzed data were not considered normal, the Friedman test was used (p < 0.05).
The activity of the masseter and buccinator muscles increased significantly after 30 days (T1) and 120 days (T2) after bichectomy compared to T0. The number of chewing cycles and time until swallowing and anxiety did not change significantly over time. Aesthetic satisfaction increased significantly after 30 days.
Removing the main body of the Bichat ball increased the electrical activity of the masseter and buccinator muscles during chewing of the tested foods. The participants' anxiety level over time was considered clinically acceptable. Buccal fat pad removal did not influence the number of chewing cycles and chewing time until swallowing. Aesthetic satisfaction increased 60 days after bichectomy. After 120 days of buccal fat pad removal, there was an improvement in the quality of life of the individuals.
评估咬肌、颞肌和颊肌的肌电活动，以及双侧颊脂垫切除术（bichectomy）后的焦虑水平、美学满意度和生活质量。
纳入9例患者。对咬肌、颞肌前部和颊肌进行肌电图检查，并评估咀嚼周期数和吞咽前的咀嚼时间。使用问卷评估焦虑水平（广泛性焦虑障碍-7量表）、手术对生活质量的影响（格拉斯哥获益量表-GBI）以及患者的美学满意度。在手术前（T0）、手术后60天（T1）和手术后120天（T2）进行评估。采用双向重复测量方差分析，当分析的数据不被认为呈正态分布时，使用弗里德曼检验（p < 0.05）。
与T0相比，双侧颊脂垫切除术后30天（T1）和120天（T2）咬肌和颊肌的活动显著增加。咀嚼周期数、吞咽前的时间和焦虑水平随时间没有显著变化。美学满意度在30天后显著提高。
切除颊脂垫主体增加了在咀嚼测试食物时咬肌和颊肌的电活动。随着时间推移，参与者的焦虑水平在临床上被认为是可接受的。颊脂垫切除术不影响咀嚼周期数和吞咽前的咀嚼时间。双侧颊脂垫切除术后60天美学满意度提高。颊脂垫切除120天后，个体的生活质量有所改善。
