Submucous cleft palate patients most commonly exhibit circular velopharyngeal closure. High-pressure consonant deletion is the frequent speech abnormality, with errors increasing with poorer velopharyngeal function.
Area of Science:
- Craniofacial Surgery
- Speech Pathology
- Pediatric Otolaryngology
Background:
- Submucous cleft palate (SCP) presents unique challenges in velopharyngeal function.
- Understanding velopharyngeal closure patterns is crucial for speech outcomes in SCP patients.
Purpose of the Study:
- To characterize velopharyngeal closure patterns in patients with SCP.
- To evaluate speech performance, including articulation, in this patient cohort.
- To correlate velopharyngeal closure with speech outcomes.
Main Methods:
- Retrospective analysis of 353 SCP patients (2008-2016).
- Subjective speech evaluation (velopharyngeal function, articulation).
- Objective nasopharyngeal endoscopy (soft palate and pharyngeal wall mobility).
Main Results:
- Velopharyngeal incompetence (VPI) was observed in 49.86% of patients.
- Circular closure pattern was most common (62.31%) during endoscopy.
- Consonant elimination (35.13%) and compensatory articulation (14.45%) were prevalent speech errors.
- Articulation errors were more frequent in patients with lower velopharyngeal closure rates.
Conclusions:
- Circular closure is the predominant velopharyngeal pattern in SCP.
- High-pressure consonant deletion is the most common articulation abnormality.
- Impaired velopharyngeal closure significantly impacts articulation in SCP patients.
