Transverse relationships of the infraorbital foramina in cleft and noncleft individuals

Abstract

An evaluation of the location of the infraorbital foramina in a transverse plane was undertaken by direct skull and radiographic measurements in unrepaired cleft palate and age- and sex-matched noncleft individuals. Physioprints were obtained on six dry skulls with left-sided clefts of the primary and secondary palates and on six age- and sex-matched noncleft palate skulls. The left infraorbital foramen was found to be significantly superior in a transverse plane to the right infraorbital foramen in the cleft palate skulls. No significant differences in transverse location of the infraorbital foramina were found in the cleft skull group based on differences in sex or age. Posterior-anterior cephalographs were obtained on 15 left unilateral cleft palate individuals and on age- and sex-matched noncleft palate individuals. The location of the infraorbital foramina in a transverse plane in the posterior-anterior cephalographs was found to be too variable to permit the use of parametric statistical tests. When the data on location of the infraorbital foramina were analyzed by a nonparametric statistical test it was found that the left infraorbital foramen was significantly superior to the right infraorbital foramen in the cleft palate individuals. The more superiorly placed infraorbital foramen on the cleft side was suggestive of a vertical deficiency of the maxilla on the cleft side.

Bilateral Variations and Sexual Dimorphism in Morphometric Parameters of Infraorbital Groove, Canal and Foramen in Human Foetuses

“…Foetal repair of the congenital diaphragmatic hernia was technically made possible by Soper (1984). Establishment of the correlation between location of the anterior end of infraorbital foramen and cleft palate by McKinstry (1987) has further enhanced the scope of study on foetal anatomy.Some information about the morphometry of foetal maxillary anatomy is available in literature (Ghaus & Faruqi, 2006, 2007 but bilateral variations and sexual dimorphism of foetal infraorbital groove, canal and foramen are lacking although such records will be of great forensic and surgical importance.…”

Morphometric Analysis of Infraorbital Foramen and Infraorbital Canal in Human Feotuses

“…Foetal repair of the congenital diaphragmatic hernia was technically made possible by Soper et al (1984). McKinstry(1987) for the first time established correlation between location of the anterior end of infraorbital canal and cleft palate. Such correlation has further enhanced the scope of study on foetal anatomy.…”
