MEDINA RUIZ, Blás Antonio et al. Use of the sternocleidomastoid muscle collar flap in the surgical treatment of the pharyngostoma. Case report and literature review. An. Fac. Cienc. Méd.

Pharyngocutaneous fistula is defined as a dehiscence of the closing of the pharyngeal mucosa, which produces leakage of saliva and communication of pharyngeal light with the skin. It can be classified as a fistula proper, in which a fistulous tract communicates light from the digestive tract with the outside and in a pharyngostoma in which the pharyngeal lumen opens directly to the outside with significant loss of soft tissues. It is a frequent complication after open surgeries of the larynx, and may also appear after surgery of the pharynx, spinal column, mandibular reconstructions as well as surgeries of the floor of the mouth. Although they can close spontaneously or with conservative treatment, many of them, especially when there is a wide communication between the pharynx and the skin, require surgery. There are several surgical techniques to close these fistulas. We present a case in which the excresis of a tongue-based tumor was performed, due to uncontrollable bleeding, with a suprahyoid pharyngotomy as the approach, presenting as a postoperative complication a pharyngocutaneous fistula followed by the formation of a broad pharyngostoma. He was treated surgically with a synthesis of the defect and reinforcement with a muscular flap in a collar with the bilateral sternocleidomastoid sternal fascicle. The patient presented good evolution with closure of the fistula.
