Objective Assessment of stability of the advanced maxilla after two-jaw surgery and Le Fort I osteotomy in patients with cleft palate based on soft tissue planning. Subjects Between 1995 and 1998, 15 patients with cleft lip and palate deformities underwent advancement of a retruded maxilla, without insertion of additional bone grafts. Eleven patients had bimaxillary osteotomies and four patients only a Le Fort I osteotomy. Relapse of the maxilla in horizontal and vertical dimensions was evaluated by cephalometric analysis after a clinical follow-up of at least 2 years. Results In the bimaxillary osteotomies, horizontal advancement was an average 4 mm at point A. After 2 years, there was an additional advancement of point A of an average of 0.7 mm. In the mandible, a relapse of 0.8 mm was seen after an average setback of 3.9 mm. In the four patients with Le Fort I osteotomy, point A was advanced by 3.8 mm and the relapse after 2 years was 0.9 mm. Vertical elongation at point A resulted in relapse in both groups. Impaction of the maxilla led to further impaction as well. Conclusion Cephalometric soft tissue analysis demonstrates the need for a two-jaw surgery, not only in severe maxillary hypoplasia. Alteration of soft tissue to functional harmony and three-dimensional correction of the maxillomandibular complex are easier to perform in a two-jaw procedure. It results in a more stable horizontal skeletal position of the maxilla.

Vertical maxillary excess is associated with gummy smile, incompetent lip,  bimaxillary proclination, Angle’s class-I or class-II malocclusion with or without retogenia. After proper evaluation preoperative orthodontic treatment was performed in every cases and superior repositioning of the maxilla by Le Fort-I osteotomy is presented. Three patients with maxillary excess associated with retrogenia or microgenia were treated with this technique in combination with genioplasty. The maxillary segment was repositioned a maximum of 7.0 mm superiorly at point A. The mandible autorotated anterosuperiorly to achieve sound occlusion. Point B moved 1.0–3.0 mm anteriorly and 5.0–8.0 mm superiorly. The pogonion moved 4.0 mm anteriorly in a case done without genioplasty and the pogonion moved maximum 8.0mm in case done in combination with genioplasty. All patients obtained sound occlusion and a good profile after the operation. Almost no skeletal relapse was observed during 3 years of postoperative follow-up. Amount of gingiva showing during smile was ranges from 5.0mm –7.0mm which was 0-2.0mm after superior repositioning of the maxilla. Ban J Orthod & Dentofac Orthop, April 2016; Vol-6 (1-2), P.1-5

Rhinosporidiosis is a rare, chronic, granulomatous infection of the mucous membranes that mainly involves the nose and nasopharynx; it occasionally involves the pharynx, conjunctiva, larynx, trachea and, rarely, the skin. The characteristic clinical features of this disease include the formation of painless polyps in the nasal mucosa or the nasopharynx that bleed easily on touch. At our center, excision of the lesion with a Le Fort I osteotomy is carried out in patients (1) in whom two or more previous attempts at excision of biopsy-proven rhinosporidiosis arising from the nasal mucosa was carried out or (2) in whom the rhinosporidiosis arises from the nasophayrngeal mucosa and/or extranasal sites. In this article we retrospectively present 7 cases in which, according to our inclusion criteria, complete excision of the lesion was carried out with a Le Fort I osteotomy. Excellent visualization of the entire maxillary and ethmoidal air cells after the down-fracture of the maxilla helped in the total removal of the lesions. Most of these lesions had multiple points of origin through the nasal, maxillary, and ethmoidal mucosa; the excellent visualization enabled direct cauterization of all these points of origin. The mean follow-up period was 7.96 years, and all patients were disease-free by the time the study was prepared. This article presents details of the treatment protocol and technique followed at our center for the treatment of nasopharyngeal rhinosporidiosis and the details of long-term follow-up. Through this study we hope to prove the efficacy of Le Fort I osteotomy in the definitive management of nasopharyngeal rhinosporidiosis.
