Successful management of the supraclavicular artery island flap combined with a sternohyoid muscle flap for hypopharyngeal and laryngeal reconstruction.

This retrospective study evaluated operative outcomes when using a supraclavicular artery island flap (SAIF) combined with a sternohyoid muscle flap (SHMF) to reconstruct defects after hypopharyngeal carcinoma resection. Reconstructive surgery for hypopharyngeal and laryngeal defects was performed with the SAIF + SHME combination in 6 patients during 2016 to 2018. Within 14 to 16 days after the surgery, all 6 patients could ingest food and block the tube (avoiding aspiration), with no pharyngeal fistulas. They then underwent irradiation up to a total of 60.5 Gy during the 4 weeks postoperatively. All 6 flaps survived, and there were no donor-site complications except minor dehiscence in 1 patient. Thus, the SAIF + SHMF combination can be used to reconstruct hypopharyngeal and laryngeal defects after hemi-laryngectomy in patients with hypopharyngeal carcinoma involving the unilateral larynx. This technique effectively preserved the swallowing function and phonation of the patients, thereby improving their quality of life.
