Özet

Objectives

This study aimed to anatomically evaluate the infraorbital canal (IOC) by comparing patients with cleft lip and palate (CLP) and controls.

Design

Retrospective cross-sectional observational study.

Setting

Department of Oral and Maxillofacial Radiology, Faculty of Dentistry.

Participants

Sixty-four children and adolescents aged 13–18 years were included: 36 with unilateral CLP (UCLP), 12 with bilateral CLP (BCLP), and 16 controls.

Interventions

None; purely observational.

Main Outcome Measure(s)

Cone-beam computed tomography scans were analyzed bilaterally and grouped as cleft side of UCLP (UCLP-CS), non-cleft side of UCLP (UCLP-NCS), BCLP, and control. Parameters examined included initial and termination diameters of the IOC (DIOF and DC), IOC length (IOF-C), direct distance between the infraorbital foramen and groove (IOF-S), distances from the IOC to the midline and lateral nasal cavity wall (MW and LNW), anterior, posterior, and horizontal angles of the IOC, IOC protrusion type and the presence of septa and Haller cells in the maxillary sinus.

Results

There was no significant difference for age and gender between the groups (p = .890 and p = .879). In the UCLP-CS group, the DC, IOF-C, MW, and LNW values were significantly lower compared to the control group (p = .034, p = .035, p = .007, p = .003, and p = .012). IOF-S values were significantly lower in the UCLP-NCS group compared to the control group (p = .041).

Conclusions

Cleft conditions can affect IOC position and morphology, especially on the cleft side of UCLP patients, and should be considered during surgery or anesthesia.
