Summary Velopharyngeal incompetence is a contributing factor for speech disorders, and other frequently accompanying disorders, such as cleft palate, congenital paralysis of the soft palate and cerebrovascular disease. A palatal lift prosthesis (PLP) has been fabricated for managing velopharyngeal incompetence to improve speech. Because of discomfort, such as difficulty in swallowing or vomiting reflex, while wearing the PLP, rigorous adjustment is required. Patients may have difficulty becoming accustomed to using the prosthesis. This article reports on a newly developed device, the nasal speaking valve, for improving hypernasal speech caused by velopharyngeal incompetence.
