Pharyngeal wall and soft palate motion after two common speech surgeries

Area of Science:

• Craniofacial Surgery
• Speech Pathology
• Otolaryngology

Background:

• Velopharyngeal insufficiency (VPI) affects speech clarity.
• Surgical interventions aim to improve velopharyngeal closure.
• Understanding anatomical motion changes post-surgery is crucial.

Purpose of the Study:

• To evaluate the impact of Furlow palatoplasty and pharyngeal flap surgery on pharyngeal wall and soft palate motion in patients with VPI.
• To provide objective data on how these surgical techniques influence velopharyngeal function.

Main Methods:

• Retrospective observational study of 17 patients undergoing Furlow palatoplasty or pharyngeal flap surgery.
• Pre- and postoperative nasopharyngoscopy recordings analyzed using a modified Golding-Kushner scale.
• Statistical analysis (paired t-test) compared motion scores; reliability assessed via intra-class correlation (ICC).

Main Results:

• Furlow palatoplasty (n=9) showed increased left soft palate motion (p=0.02).
• Pharyngeal flap surgery (n=8) demonstrated increased lateral pharyngeal wall motion (p<0.008) and right soft palate motion (p=0.04).
• Inter- and intra-rater reliability were lower than in previous studies.

Conclusions:

• Furlow palatoplasty and pharyngeal flap surgery enhance velopharyngeal closure through distinct anatomical motion improvements.
• Objective evidence supports differential effects on palatal and pharyngeal wall movement.
• Preoperative assessment of motion may guide surgical technique selection for VPI.
