palatopharyngeal incompetence การใช้

• Palatopharyngeal incompetence should not be confused with palatopharyngeal insufficiency.
• Palatal lift prostheses are designed to address palatopharyngeal incompetence.
• Such patients can suffer from residual palatopharyngeal incompetence that could necessitate the fabrication of palatal lift prostheses that occlude the offending nasopharyngeal ports.
• Since surgical management generally eliminates the need for a palatal lift prosthesis and its incumbent disadvantages, the pharyngeal flap surgical procedure is often favored as a first option for addressing palatopharyngeal incompetence.
• A palatal lift prosthesis addresses palatopharyngeal incompetence by physically displacing the dysfunctional soft palate in the hope of closing the palatopharyngeal port enough to mitigate hypernasal speech and / or prevent nasopharyngeal regurgitation of liquids or solids during the pharyngeal phase of swallowing.
• As such, midsagittal pharyngeal flaps designed to be wide enough to mitigate palatopharyngeal incompetence in patients with minimal lateral pharyngeal wall adduction run the risk of being so wide they fail to allow the preservation of bilateral palatopharyngeal ports large enough to safeguard the capacity for nasal respiration.
• While palatopharyngeal incompetence and palatopharyngeal insufficiency contribute to similar symptomatology as they relate to speech and swallowing, the former results from a hypomobility or paralysis of intact anatomy that is normally responsible for effecting palatopharyngeal closure while the latter results from a congenital or acquired absence of that anatomy.
