Endoscope-assisted second branchial cleft cyst resection via an incision along skin line on lateral neck

The aim of the study is to report the feasibility of endoscope-assisted second branchial cleft cyst resection via a small incision along the skin line on the lateral neck. In total, 41 patients from the Department of Otolaryngology, Foshan Hospital of Yat-sen University were randomly assigned to conventional (20 patients) or endoscope-assisted (21 patients) second branchial cleft cyst resection. The patient clinical characteristics, operation time, operative bleeding volume, postoperative complications, and subjective satisfaction with the incision scar (measured using a visual analog scale) were compared between the groups. All 41 s branchial cleft cyst resections were successfully performed, and the wounds healed uneventfully. The bleeding volume (6.3 ± 2.5 ml) and incision length (2.7 ± 0.3 cm) differed between the groups (P < 0.00). The mean patient satisfaction score was 8.0 ± 0.8 in the endoscope-assisted surgery group and 6.4 ± 0.9 in the control group (P < 0.00). All of the patients in the endoscope-assisted surgery group were satisfied with their cosmetic results. No marginal nerve palsy occurred. No complications such as bleeding, salivary fistula, or paresis of the marginal mandibular branch occurred. All of the patients were disease free through a follow-up period of 6–24 months (median: 14 months). Endoscope-assisted second branchial cleft cyst resection via a small incision along the dermatoglyph on the lateral neck is a feasible technique. This procedure may serve as an alternative approach, allowing a minimally invasive incision and better cosmetic results.
