“…Besides the complications mentioned in the study, some rarely occurring complications following Le fort I osteotomy such as nasolacrimal duct injury, blindness, deviated nasal septum, carotid-cavernous fistula and total avulsion of lateral segment of palate have been documented [3]. But new innovative techniques and better understanding of anatomy has led to reduction in the incidence of these complications to almost negligible.…”

“…Bendor-Samuel et al [3] reported a left Occulomotor palsy following a Le Fort I osteotomy occurring as a result of a fracture of the base of skull, leading to a cavernous sinus injury with probable thrombosis and carotid-cavernous fistula. Newlands et al reported a rare case of an ipsilateral sixth nerve palsy and partial third nerve palsy following a Le Fort I osteotomy and proposed fracture at superior orbital fissure as injury mechanism [19].…”

“…Overall complication rate has been reported to range from 6.1 to 9 % [3,4] which can vary to a large extent for various individual complications. This variability may be owing to the difference in surgical skill and technique or diagnostic criteria used.…”

Le Fort I osteotomy has become a routine procedure in elective orthognathic surgery. This procedure is often associated with significant but rare post-operative complications. The study was conducted to evaluate the rate of post-operative complications following conventional Le Fort I osteotomy. Twenty-five healthy adult patients who had to undergo Le Fort I osteotomy without segmentalization of maxilla were included in the study based on indications of surgery. All the patients were followed up for a period of 6 months post-operatively to assess the rate of various post-operative complications such as neurosensory deficit, pulpal sensibility, maxillary sinusitis, vascular complications, aseptic necrosis, unfavourable fractures, ophthalmic complications and instability or non-union of maxilla, etc. The results of our study showed a post-operative complications rate of 4 %. Neurosensory deficit and loss of tooth sensibility were the most common findings during patient evaluation at varying follow-up periods while one patient presented with signs and symptoms of maxillary sinusitis post-operatively. Neurosensory as well as sinusitis recovery took place in almost all the patients within 6 months. It was concluded that thorough understanding of pathophysiological aspects of various complications, careful assessment, treatment planning and the use of proper surgical technique as well as instrumentation may help in further reducing the complication rate.

“…Bendor-Samuel et al [1] reported three rare complications associated with Le Fort I osteotomy. In the first case, unilateral third nerve palsy occurred from iatrogenic carotid cavernous fistula and false aneurysm of the internal carotid artery after treating maxillary hypoplasia secondary to a bilateral complete cleft of the primary and secondary palate.…”

Purpose: This study is to evaluate the location of descending palatine artery, the anatomy of pterygomaxillary junction, and the association between the obtained anatomic values and several variables. Methods: We studied 40 patients who were treated for dentofacial deformites from January 2010 to December 2012 in Ulsan University Hospital, Ulsan, Korea. Cone beam computed tomogram (CBCT) was done for all patients. The reference point was approximately 5 to 7 mm above anterior nasal spine on axial image. We evaluated the location of the greater palatine canal (line a: on the coronal view, the shortest line between the center of greater palatine canal and pterygoid fossa; distance a: the distance of line a). We also measured the thickness (line b: on the coronal view, the shortest line between maxillary posterior sinus wall and pterygoid fossa; distance b: distance of line b), width (line c: on the coronal view, the line perpendicular to the line b and the nearest line from the most concave point of lateral pterygoid plate to the medial pterygoid plate; distance c: distance of line c) and height (line d: on sagittal view, the vertically longest line of pterygoid junction; distance d: the distance of line d) in pterygomaxillary junctions. We evaluated the association between the obtained anatomic values and several variables (sex, age, height and weight). Results: The mean distance a was 4.78 mm, mean distance b was 5.53 mm, mean distance c was 8.01 mm and mean distance d was 13.22 mm. The differences between age and mean distance c and weight and mean distance d in pterygomaxillary junctions are statistically significant. Conclusion: There apparently is anatomic variation of pterygomaxillary junctions by various values, particularly weight and age in a Korean clinical population.
