Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Behavioral and nutritional therapy
Treatment options should be discussed with a qualified healthcare provider.
Cricopharyngeal Myotomy
Surgical procedure to relieve swallowing difficulties by relaxing the upper esophageal sphincter muscle. Significantly improves dysphagia and reduces aspiration risk in appropriate candidates.
Speech and Swallowing Therapy
Specialized therapy focusing on safe swallowing techniques, muscle strengthening exercises, and strategies to maintain oral intake while minimizing aspiration risk.
Additional treatment options
Ptosis Repair and Eyelid Surgery
Surgical correction of eyelid drooping to improve vision, reduce eye fatigue, and enhance facial appearance. May be performed as a day case procedure.
procedureRespiratory Function Assessment
Regular monitoring of respiratory muscle strength and pulmonary function due to risk of respiratory involvement. Includes periodic spirometry and assessment of nocturnal breathing.
monitoringModified Texture Diet Planning
Dietary modifications including texture-modified foods and thickened liquids as needed to ensure safe nutrition intake while compensating for swallowing difficulties.
