A Case of Hypopharyngeal Stenosis Associated with Laryngeal Cancer Treatment Reconstructed with a Pectoralis Major Myocutaneous Flap Using a Strip of the Posterior Pharyngeal Mucosa

Dysphagia after total laryngectomy is rare.Even when it occurs, it often improves with bougienage or endoscopic treatment by an otolaryngologist.However, in the present case, the patient's dysphagia was severe and progressive owing to the effects of radiation therapy, prompting consultation with reconstructive surgery.The contracted pharyngeal mucosa was released under direct visualization, and well-vascularized flap transplantation was performed.Pectoralis major myocutaneous flap reconstruction using a strip of the posterior pharyngeal mucosa has maintained a good swallowing function over the long term.
