Summary
Young patients with unilateral cleft lip and palate (UCLP) show smaller maxillary sinus volume (MSV) on the affected side. This hypoplasia is linked to the anterior sinus region and restricted vertical development.
Area of Science:
- Craniofacial anatomy
- Pediatric dentistry
- Oral and maxillofacial surgery
Background:
- Unilateral cleft lip and palate (UCLP) can affect facial development.
- Maxillary sinus volume (MSV) and dimensions may be altered in UCLP patients.
Purpose of the Study:
- To compare MSV and linear measurements between cleft and non-cleft sides in UCLP patients.
- To identify specific regions of the maxillary sinus affected by UCLP.
Main Methods:
- Retrospective cohort study of 20 young UCLP patients.
- Cone Beam Computed Tomography (CBCT) analysis.
- Comparison of MSV and linear measurements (length, width, height) of the entire sinus, anterior, and posterior parts.
Main Results:
- Significantly smaller MSV on the cleft side (p=0.03).
- The anterior part of the maxillary sinus showed reduced volume on the cleft side (p=0.001).
- A smaller anterior/posterior height ratio was observed on the cleft side (p<0.001).
Conclusions:
- MSV is significantly reduced in young UCLP patients on the cleft side.
- Maxillary sinus hypoplasia in UCLP is primarily associated with the anterior region.
- Evidence suggests restricted vertical development of the maxillary sinus in UCLP patients.
