Abstract
The cricopahryngeal myotomy was performed in four dysphagic patients with cerebrovascular diseases. Case 1: male, 77 years of age, infarction of brain stem and cereblum. He was admitted to our hospital with tracheotomy and a nasal tube. He underwent the cricopharyngeal myotomy on both sides and thyroid cartilage and mandibular bone approximation. He became less dysphagic, however, needed nasal feeding after surgery. Case 2: male, 73 years of age, Wallenberg syndrome. He was admitted to our hospital with a nasal tube. He underwent cricopharyngeal myotomy on both sides and thyrohyoidpexy. He became less dysphagic, however, needed nasal feeding after surgery. Case 3: male, 49 years of age, infarction of brain. He was admitted to our hospital with trachy otomy and a nasal tube. He underwent the cricopharyngeal myotomy on both sides and thyroid car tilage and mandibular bone approximation. He became less dysphagic, however, needed nasal feeding. Case 4: female, 55 years of age, rupture of PICA. She was admitted to our hospital with trachyotomy and a nasal tube. She underwent the cricopharyngeal myotomy on both sides. She be came free from dysphagia and was discharged without a nasal tube after surgery. Case 1 was aged and with poor ADL. Case 2 was aged and with good ADL. Case 3 was young and with poor ADL. Case 4 was young and with good ADL. The results of the cricopharyngeal myotomy do not depend on the severity of dysphagia, but depend on the age and ADL of the patients.
