ABSTRACT

Cricopharyngeal dysfunction is produced when muscle is not relaxed properly during swallowing, due to delayed or incomplete relaxation of cricopharyngeal muscle that may be due to multiple causes. Common symptoms are dysphagia (98%), odynophagia, breathless sensation, halitosis, cough and nasal regurgitation. Aspiration and weight loss occur in severe cases, malnutrition appears even in 30% of patients and disorders of swallowing safety (penetrations and aspirations) occur in two thirds of patients, with a high risk of respiratory infections and aspiration neumonia. Treatment of cricopharyngeal muscle dysfunction includes swallowing therapy, dilatation, botulin toxin injection, transcervical cricopharyngeal myotomy and endoscopic surgery with laser. Cricopharyngeal myotomy is the standard surgical intervention used as treatment of swallowing disorders originated by an isolated dysfunction of cricopharyngeal muscle.
