What should be the expected outcome after pharyngeal flap surgery for a patient with velopharyngeal dysfunction?

After pharyngeal flap surgery for a patient with velopharyngeal dysfunction, the primary expected outcome is a reduction in hypernasality and audible nasal emission, aligning with the correct answer. This surgical intervention aims to improve the closure of the velopharyngeal port, enhancing the ability to separate nasal and oral sounds during speech. By addressing the structural issues associated with velopharyngeal dysfunction, patients often experience more effective speech mechanics, leading to clearer articulation and improved resonance.

While surgery can positively influence speech outcomes, it does not guarantee the complete elimination of all issues related to articulation or necessitate discontinuation of speech therapy. Hence, the focus remains on the overall improvement in speech clarity, especially concerning the problematic aspects of hypernasality and nasal airflow during phonation.
