Evaluation of Orbitomalar Region Projection in Patients With Operated Cleft Lip and Palate (Cephalometric Study)

Abstract

Objective The aim of this study was to compare the orbitomalar region projection in patients with cleft lip and palate (CLP) with skeletal class 1 cases. Design Retrospective. Setting Single center. Patients Cephalometric data of 52 cases with unilateral CLP, 25 cases with bilateral CLP, and 60 healthy participants in skeletal class 1 without CLP were included. Main Outcome Measure(s) A total of 5 parameters, 3 in the orbital and 2 in the suborbital region, that determine the projection of the orbitomalar region on lateral cephalograms, and 13 parameters of the craniofacial region were evaluated. Results Lateral, inferior, and anterior orbital parameters were similar between groups, while suborbital parameters were in a retrusive position in the CLP groups compared to the control group ( P < .05). No significant difference was found between the CLP groups in terms of suborbital parameters. A moderate positive correlation was found between orbitomalar parameters and the anteroposterior positions of the maxilla and mandible. The lateral orbital region had a moderate negative correlation with anterior maxillary height, and the suborbital region had a negative moderate correlation with maxillary inclination. Conclusion Suborbital projection was more retrusive in CLP compared to the control group, but no difference was found between the CLP groups. On the other hand, the correlation between orbitomalar projection and maxillary and mandibular development was significant. The results show that there is a need for alternative treatment modalities for the suborbital region in patients with CLP.

Unilateral Cleft Lip and Palate Has Asymmetry of Bony Orbits: A Retrospective Study

“…Anchlia et al [30] reported ocular abnormalities in cleft lip and palate patients (n = 322) with and without syndromes. Orbital defects (hypotelorism and telecanthus) were found in 17% of patients [35]. In a large data collection from Texas Birth Defects, 21% of non-syndromic infants with cleft lips with or without palate (n = 5289) had at least one additional congenital anomaly.…”

“…In a 3D-surface scanning follow-up study, 90% of the patients with UCS (n = 22) had significant facial asymmetry throughout the facial area [40]. Marked orbital asymmetry has been linked to hemifacial microsomia [35]. Orbital volume was 10% smaller on the affected side in 80% of patients [41].…”

Hipoplasia maxilar primária do paciente com fissura labiopalatina transforame unilateral: correlação com dados clínicos

“…melhor ranqueamento apresentaram 10% ou menos dos casos nos grupos 4 e 5) 85 , e o Americleft, (onde os melhores escores médios atingidos foram 2,6 e 3,3)58 . A observação deste índice desfavorável, no entanto, poderia ser justificada, em parte, pela hipoplasia maxilar primária 131. o prejuízo desse desenvolvimento seria atribuído a três fatores: deficiência intrínseca secundária à fissura, inibição do crescimento como resultado da cirurgia corretiva durante a infância precoce e fatores genéticos.…”
