Theory and practice of laparoscopic surgery against omohyoid muscle syndrome.

Omohyoid muscle syndrome (OMS) is a rare disease characterized as a protruding lateral neck mass feature during swallowing. Because there is a 5 cm scar after traditionally surgery, we designed a laparoscopic surgery procedure to meet the cosmetic needs of patients. From the year 2006 to 2016, there were 3 patients diagnosed as omohyoid muscle syndrome that underwent laparoscopic surgery. Operative and postoperative follow-up data were summarized. Average surgery time was 35 ± 13 min. Average blood loss was 3 ± 1 mL. No case converted to open surgery. No major vessel or nerve damage complications occurred. After the surgery, the neck mass completely disappeared during swallowing, and there were no operative scars on the neck. All patients were discharged within 2 days. During the follow-up of a year, no recurrence occurred. In conclusion, the endoscopic procedure is suitable for OMS. It's a safe, effective and cosmetic surgery.
