Swallowing function improvement using costal cartilage for severe dysphagia after supracricoid hemilaryngopharyngectomy.

Supracricoid hemilaryngopharyngectomy (SCHLP) is a laryngeal preservation surgery for hypopharyngeal carcinoma confined to the pyriform sinus or laryngeal carcinoma with arytenoid infiltration. Postoperative dysphagia is inevitable, but both voice and swallowing functions can be preserved. Here, we present a case of severe dysphagia secondary to unexpected postoperative tissue loss and scarring. A 67-year-old man underwent left SCHLP for hypopharyngeal cancer, and on the third postoperative day, he developed necrotizing fasciitis of the left neck. He was unable to swallow and was transferred to a rehabilitation hospital 90 days after the surgery. Six months after surgery, the patient had significant glottic insufficiency due to laryngeal deformity, constant massive salivary aspiration, and difficulty releasing the cuffed cannula. Severe dysphagia due to glottic insufficiency and laryngeal elevation insufficiency due to scar formation were considered, and laryngoplasty and laryngeal suspension surgery using costal cartilage were performed on the 221st postoperative day. After the reoperation, he was able to wear a speech valve and could speak and spit out, although his glottis was still closed. On the 70th day after the reoperation, he was able to consume three meals of an oral dysphagia diet and was discharged home. [ABSTRACT FROM AUTHOR]
