[Clinical application of retroauricular hairline approach in submandibular gland resection assisted by endoscope].

ABSTRACT

Objective:To investigate the clinical effect of retroauricular hairline approach in submandibular gland resection assisted by endoscope. Methods:A total of 18 patients with submandibular gland benign tumors treated in our hospital from September 2022 to September 2023 were selected. A 5 cm incision was designed in the retroauricular hairline, and the flap was turned over directly to the anterior edge of sternocleidomastoid muscle, then the flap was turned over to build the cavity through endoscopic surgery, and submandibular gland resection was completed with the assistance of endoscope. After operation, a negative pressure drainage was placed into the hairline, and the wound was closed by continuous intracutaneous suture. The clinical effect was evaluated after 3-6 months follow-up. Results:All patients underwent submandibular gland resection with endoscopic assistance as planned, and none of them converted to submaxillary incision during operation. The operation time was 65-97 min, with an average of 75 min. Intraoperative bleeding was 10-20 mL, with an average of 14 mL.No tongue numbness, wound infection, or tumor recurrence occurred after operation. However, there were 10 patients with ear numbness and discomfort of auricle after surgery, which gradually recovered after 6-9 months of follow-up. Two patients had crooked mouth after surgery, and the symptoms were gradually relieved after follow-up. All incisions healed in stage I and were concealed. Conclusion:Endoscopic retroauricular hairline approach is a choice for submandibular gland resection with good cosmetic effect, less trauma and fewer complications.
