Clinical Course of Dysphagia in Patients with Nemaline Myopathy

Nemaline myopathy (NM) is a rare congenital myopathy, a group of disorders that are clinically and genetically heterogeneous. Infants and children with NM often suffer from recurrent pulmonary infections and swallowing difficulty, leading to malnutrition. However, knowledge about the clinical course and prognosis of dysphagia is limited. In this study, we reported the clinical course of two NM patients suffering from dysphagia. Although tube feeding was required for several months after birth, it was eventually possible to obtain sufficient nutrition with an oral diet. Therefore, dysphagia rehabilitation therapy through a series of evaluations should be considered even in children with severe oral motor dysfunction. Through these cases, physicians should be convinced that the symptoms of dysphagia in children with NM can be improved and be able to encourage their parents by explaining this progress. They have the potential to show improvements in swallowing function and will finally be able to take food slowly but fully orally.
