Abstract
In Le Fort I osteotomies that require superior repositioning of the maxilla, surgeons are confronted with different anatomical
problem. The surgeon should consider the condition of the infraorbital foramen and apex of maxillary teeth to determine the
best bone resection route. The purpose of this study was to evaluate the limit of superior repositioning of the maxilla in Le Fort I
osteotomy by measuring the distance between the apex of the maxillary teeth with the plane between the bilateral infraorbital nerve
and the porion. Our study was performed on 74 segments of 37 patients between the ages of 18 and 25 years (19.21 ± 1.87; mean ±
SD). Of these, 50 were male (67.6%) and 24 were female (32.4%). The mean distance of the between infraorbital foramen plane and
the teeth was 16.95 ± 3.87mm for canines, 20.64 ± 3.69 mm for first premolars, 20.53 ± 4.05 mm for second premolars, 20.26 ± 3.56
for first molars, and 19.79 ± 3.62mm for second molars when genders were evaluated there was no statistically significant difference
between canine teeth distance (p > 0.005), but there was a statistically significant difference between premolars and molars (p <
0.005). When the length of the plane distance were evaluated by the right or left region, there was no difference between the canine,
premolar or molar teeth (p>0.005). According to our results, the vertical height of the infraorbital foramen is a convenient landmark
in superior repositioning of the maxilla with Le Fort I osteotomy.
