Background:
Surgical scars are a significant cosmetic problem, especially when in exposed areas such as the anterior neck. To avoid or reduce visible scarring, diverse innovative surgical approaches to the neck have been introduced. The purpose of this study was to evaluate the feasibility and safety of the endoscopic resection using the retroauricular approach for submandibular gland excision.
Methods:
The present study enrolled 48 patients who underwent conventional transcervical submandibular gland excision and 23 patients who underwent endoscope-assisted retroauricular approach submandibular gland excision, from February 2014 through February 2018 at the Department of Head and Neck Surgery and Otorhinolaryngology of the AC Camargo Cancer Center, in Sao Paulo, Brazil. The surgical outcomes were retrospectively reviewed.
Results:
In the conventional group, 26 (54%) patients were male. The mean age was 49.3 years (range 22-81). Twenty-two patients (46%) had sialoadenitis; twenty-one (44%) had benign and five (10%) had malignant tumors. The mean total surgical time was 86.4 min (range 40-180), and the mean total length of hospital stay was 1.3 days. Twenty-seven (56%) patients suffered from local postoperative complications in the neck. In the retroauricular group, 14 (61%) patients were male. The mean age was 44.1 years (range 24-71 years). Seven patients (31%) had sialoadenitis, twelve (53%) had benign tumors and four (16%) had malignant tumors. The mean total surgical time was 86.4 min (range 75-300 min), and the mean total length of hospital stay was 1.2 days. Twelve (53%) patients suffered from local postoperative complications in the neck. No surgical site infections or systemic complications were described.
Conclusions:
The retroauricular endoscopic-assisted submandibular gland resection is feasible, with excellent cosmetic results and no significant complication rate increase, and can be a safe potential surgical alternative for patients who are motivated to avoid a visible neck scar.
