Recurrent laryngeal nerve injuries after esophagectomy.

摘要

Unilateral vocal-cord paralysis after esophagectomy involving a cervical anastomosis is uncommon in experienced hands but can cause marked morbidity because of pulmonary complications. It is important for the surgeon to understand the anatomy of the recurrent laryngeal nerve to avoid this complication. The diagnosis is usually easily made at the bedside and can be confirmed by visualization of the glottis. Early treatment may include supportive care with a speech pathologist or injection of the vocal-cord with temporary material to improve glottic closure. Definitive treatment can best be performed by medialization thyroplasty.
