A miotomia do cricofaríngeo: artigo de revisão

Abstract: A miotomia do cricofaríngeo é um procedimento cirúrgico que pode ser indicado para pacientes com disfagia orofaríngea que, em geral, caracterize-se por distúrbio motor limitado à fase faríngea da deglutição, incoordenação cricofaríngea ou relaxamento incompleto do Esfíncter Esofágico Superior (EES). A indicação da miotomia, porém, tem sido discutida e aplicada em muitos casos, sem efeito na melhora da dinâmica da deglutição.

“…The pathophysiology of the disease is still in debate, but the most accepted hypothesis is that there is a high hypopharynx pressure on the muscles of the Killian-Laimer’s triangle, caused by fibrosis and motor dysfunction of the upper esophageal sphincter (UES), which can result in herniation of the esophagus’ mucosa and submucosa walls, forming the diverticulum. Other theories include cricopharyngeal spasms, congenital weakness of the area and gastroesophageal reflux [ 2 , 3 , 9-11 , 14 ]. The UES is constituted by the posterior surface of the thyroid and cricoid cartilages, the cricopharyngeus muscle, the thyropharyngeus muscle and the cervical portion of the esophagus.…”
