Evaluation of the Effect of Pterygomaxillary Disjunction
on Alar Base Width in Surgically Assisted Rapid Palatal Expansion (SARPE) Using
Cone-Beam Computed Tomography (CBCT)
Objective: The aim of this study is to evaluate the
effect of pterygomaxillary disjunction on nasal base width following surgically
assisted rapid palatal expansion (SARPE) using cone-beam computed tomography
(CBCT).
Materials and Methods: A total of 40 SARPE patients
with preoperative and postoperative CBCT images were included in the study,
comprising 20 patients with pterygomaxillary disjunction (Group 1) and 20
patients without it (Group 2). Changes in nasal base measurements before and
after surgical treatment were compared between the two groups based on CBCT
images.
Results: A statistically significant increase in
postoperative nasal base width was observed in Group 1 compared to Group 2
(p=0.001). Additionally, a statistically significant increase in postoperative
nasal base width compared to preoperative width was observed in both groups
after SARPE (p=0.001).
Conclusion: Pterygomaxillary disjunction leads to a
significant increase in nasal base width following SARPE. This finding suggests
that pterygomaxillary disjunction should be considered in surgical planning.
CBCT stands out as an effective imaging method for monitoring and evaluating
such changes.
