Summary
Pharyngeal-flap surgery (PFS) for hypernasal speech may negatively impact maxillary dental arch development. Studies show reduced arch width and length in patients who underwent PFS compared to controls.
Area of Science:
- Dentistry
- Oral Surgery
- Speech Pathology
Background:
- Hypernasal speech often requires surgical intervention.
- Pharyngeal-flap surgery (PFS) is a common treatment for hypernasality.
- Potential effects of PFS on craniofacial development require investigation.
Purpose of the Study:
- To evaluate the impact of pharyngeal-flap surgery (PFS) on maxillary dental arch dimensions.
- To compare dental arch development in patients with and without PFS.
Main Methods:
- Retrospective analysis of 16 patients who underwent PFS between ages 5-7.
- Utilized serial maxillary dental models from a longitudinal growth study.
- Measured arch width and length at eight defined points on occlusal surfaces.
- Compared measurements to a matched control group without PFS.
Main Results:
- Patients who underwent PFS showed a significant reduction in maxillary arch width at cuspid and molar locations.
- A significant decrease in arch length development was observed in the PFS group.
- The flap group exhibited narrower and shorter dental arches compared to controls.
Conclusions:
- Pharyngeal-flap surgery may lead to reduced maxillary dental arch width and length.
- Findings suggest potential dental arch form changes following PFS.
- Further research is needed to explore the link between PFS, airway obstruction, and dental arch alterations.
