Abstract
Continuous positive airway pressure (CPAP) therapy can be an effective speech therapy approach for reducing hypernasality. It is based on the rationale of improving the strength and endurance of the velopharyngeal muscles specific to speech production. This investigation presents a case study involving an 8-week, 6 days per week regimen of self-administered home CPAP therapy. The study investigated whether the subject benefited from the therapy and whether the effectiveness of the CPAP therapy remained stable and constant following the therapy. A 10-year-old boy, who had exhibited persistent hypernasality after undergoing a surgical procedure to correct submucous cleft palate, was assigned the 8-week in-home CPAP therapy procedure. After completing the 8-week protocol, the boy demonstrated improvement in speech intelligibility, nasalance scores, and velopharyngeal function as measured by aerodynamic tools, and his speech was perceived as mildly hypernasal. However, the effectiveness of the initial administration of CPAP therapy was not maintained after a 5-month intermission. Subsequently, another 8-week regimen of CPAP therapy was administered, and the degree of hypernasality and speech intelligibility showed improvement once again following the second administration. This case study suggests the need for further investigation to establish more appropriate therapeutic protocols which improve the short and long-term effectiveness of the CPAP therapy procedure.
