Background: Traditional parotid surgery leaves visible submaxillary cicatrices, unaesthetic results from incisions, and a high incidence of postoperative complications. This study aimed to examine the feasibility of newly designed incisions for the removal of benign parotid lesions. Methods: The authors randomly assigned patients (n = 48) with benign parotid lesions admitted to our department from November 2016 to April 2019. In the study group, an aesthetic incision was designed through a preoperative examination combined with a medical history and physical examination. Half of the patients (n = 24) underwent surgery with the new incision design, while the patients in the control group (n = 24) received conventional surgery. The therapeutic effects and outcomes of the two groups were compared. Results: The postoperative complication rate of the study group (n = 6) was significantly lower than that of the control group (n = 15). Compared to conventional surgery, patients who received the hidden incisions had less total drainage volume, decreased length of incision, and fewer days of postoperative hospitalization (P < 0.05). On an average follow-up of 20 months, no recurrence was found in any patient. Conclusions: Minimal access incisions, aided with loupe magnification, greatly improve the surgical safety, patient outcomes, and final scar appearance. The described technique is worth further study and utilization.

Background: We evaluated the clinical applications of the reconstruction of postoperative defects of the oral cavity using contralateral submental artery flaps. Methods: A retrospective study of 18 patients with postoperative intraoral cancer defects reconstructed with contralateral submental artery perforator flaps between October 2018 and October 2019 in our department was conducted. The defect area, flap size, and complications were evaluated. Results: All patients were diagnosed based on pathological examinations: 2 with adenoid cystic carcinoma and 16 with squamous cell carcinoma. The submental artery perforator flap used for simultaneous repair was 8 to 15 cm in length and 4 to 6.5 cm in width. The survival rate of flap reconstruction was 100% with no donor site complications. Conclusions: Contralateral submental artery flap reconstruction is a suitable alternative for moderate to large intraoral defects, postoperative mouth floor defects, and oral cavity composite defects of oral malignant tumors without contralateral lymph node metastases.
