| Popis: | The purpose of this investigation was to evaluate the ability of palatal lift protheses to stimulate the neuromuscular activity of the velopharynx. Nasendoscopic evaluations were audio-videotaped preprosthetic and postprosthetic management for 25 patients who underwent placement of a palatal lift prosthesis for velopharyngeal dysfunction (VPD). These audio-videotapes were presented in blinded fashion and random order to three speech pathologists experienced in assessment of patients with VPD. They rated the tapes on the following parameters: VP gap size, closure pattern, orifice estimate, direction and magnitude of change, and qualitative descriptions of the adequacy of VP closure during speech. VP closure for speech was unchanged in 69% of patients and the number of patients rated as improved or deteriorated was nearly identical at about 15%. Postintervention gap shape remained unchanged in 70% of patients. The extent of VP orifice closure during speech remained unchanged in 57% of patients. Articulations that could impair VP function improved in 30% of patients, deteriorating in only 4%. Results of this study neither support the concept that palatal lift prostheses alter the neuromuscular patterning of the velopharynx, nor provide objective documentation of the feasibility of prosthetic reduction for weaning. |
