OBJECTIVES We evaluated the long-term results of laryngeal suspension and upper esophageal sphincter (UES) myotomy in patients with life-threatening aspiration. METHODS In the period 1995 to 2004, 17 patients with severe aspiration caused by insufficient laryngeal elevation and absent or negligible pharyngeal constrictor muscle activity during deglutition(More)
BACKGROUND Strictures of the hypopharynx and oesophagus are frequently observed following (chemo)radiation. Anterograde dilatation of a complete stenosis carries a high risk of perforation. An alternative is described: a combined anterograde-retrograde approach. CASE REPORT A 75-year-old man developed complete stenosis of the oesophageal inlet after(More)
OBJECTIVE We report two cases in which dysphagia and aspiration, caused by anterior cervical osteophytes, were so severe that surgical resection was performed. METHOD Case reports and a review of the world literature concerning dysphagia caused by anterior cervical osteophytes, in regard to pathogenesis, diagnosis and treatment. RESULTS Two patients,(More)
OBJECTIVES We assessed the efficacy of endoscopic Zenker's diverticulotomy with the carbon dioxide (CO2) laser and Acuspot and compared it with the historical results of using a CO2 laser without Acuspot and electrocautery diverticulotomy. METHODS Between 1976 and 2005, a total of 229 endoscopic Zenker's diverticulotomies in 189 patients were performed in(More)
The aim of this work was to assess the efficacy of external myotomy of the upper esophageal sphincter (UES) for oropharyngeal dysphagia. In the period 1991–2006, 28 patients with longstanding dysphagia and/or aspiration problems of different etiologies underwent UES myotomy as a single surgical treatment. The main symptoms were difficulties in swallowing of(More)
Neurofibromatosis type 1 (NF1) may present with a wide spectrum of pathologic anomalies. Very rarely it may present as a spinal meningocele, a protrusion of spinal meninges through a defect in the vertebral column or foramina. We report a case of a patient with NF1 who harbored a large retropharyngeal mass that consisted of two cervical meningoceles and(More)
Objective: We report two cases where dysphagia and aspiration, caused by anterior cervical osteophytes, were so severe that surgical resection was performed. Method: Case reports and a review of the world literature concerning dysphagia caused by anterior cervical osteophytes, in regard to pathogenesis, diagnosis and treatment. Results: Two patients, aged(More)
