The patient, 18-year-old girl, had a class III malocclusion with the lateral compression of the maxilla due to the premature loss of the canines, mild mandibular prognathism, and mouth breathing habit. The treatment plan consisted of 1) rapid maxillary expansion 2) a period of retention 3) extraction of the first mandibular premolars instead of surgical correction 4) completion of orthodontic treatment with multibanded system. The maxilla was separated in the midline by the application of orthopedic forces via a cemented rapid maxillary expansion device. After 18 months, She gained functional overbite-overjet relationship, good interdigitation of buccal segments, and facial harmony due to the retraction of lower anterior teeth.

A 23 year-old female with skeleto-dentoalveolar protrusion of maxilla, minor broken contact points between anterior teeth, and missing of lower 1st molars, has been treated with multibanded edgewise technique. After treatment of 14 months, she has gained functional overbite-overjet relationship and facial harmony due to the retraction of upper anterior teeth. Root resorption was slight. Especially, us ing the space of missed lower 1st molars instead of extracting lower premolars, expected and favorable results were obtained.

Ankyloglossia is the presence of a lingual frenulum, which can range from a mucous membrane band to a short and thick band and, in extreme cases, to fusion of the tongue to the floor of the mouth. The effects of such a condition, in addition to speech defects and occasionally restriction of sucking, including dental deformities, such as open bite, or even prognathism. Treatment is surgical. The preferred treatment is horizontal sectioning of the frenulum down to the lingual septum and then suturing of the mucosa. The main problem after the healing of surgical wound is adhesion and contracture. Adhesion restrict the movement of tongue like tongue-tie. Z-plasty at the site of incision can solve this problem by changing the direction of scar. We have experienced a patient with ankyloglossia with speech defect, who underwent frenuloomy by Z-plasty. So we present a surgical treatment of Ankyloglossia using Z-plasty and discuss the treatment with a review of literature.

Achondroplasia is characterized by undergrowth of long bones and cartilages and by low height. The name of this disease had been called classical chondrodystrophy, dyschondroplasia, chondrodystrophy and micromelia before Parrot reported the term of this disease as Achondroplasia. We are reporting in this paper on an 3-year and 4-month-old boy with achondroplasia. The dental findings are as follows: 1. Open bite and relatively mandibular prognathism were observed in the front teeth. 2. The size, number, shape, structure of the teeth were usual and the tongue was a little bigger than the normal. 3. The metacarpal bones were short and broadening. Mesial, distal border of the prox. phalanges were irregular and also trabecular pattern was abnormal in the hand-wrist P-A view. 4. According to lat. cephalometric analysis, the cranial basis was underdeveloped.

Cornelia de Lange syndrome is a disorder of unknown biochemical and geneic basis that is recognized on the basis of characteristic facies(low anterior hairline, synophrys, anteverted nares, maxillary prognathism, long philtrum, carp mouth) in association with prenatal and postnatal growth retardation, mental retardation and, in many cases, upper limb anomalies. We treated the patient with incomplete cleft palate related to Cornelia de Lange syndrome.

Purpose: Congenital factor VII (FVII) deficiency is a rare bleeding disorder and surgery can cause excessive bleeding due to an extrinsic pathway problem. It can be diagnosed by increased PT and decreased FVII level in coagulation test. Symptom varies according to the level of FVII, but it is essential to prevent intraoperative excessive bleeding. Methods: In this report, we described the orthognatic surgery experience in a mandibular prognathism patient with congenital FVII deficiency, in which recombinant activated factor VII (rFVIIa) was used to manage the bleeding. Rsults: We could get a successful result without any complication and there was minimal intraoperative bleeding. Conclusion: The orthognathic surgery could therefore be safely performed in patients with congenital factor VII deficiency using rFVIIa.

The growth changes in position of upper and lower jaws, incisal inclination in relation to inferior cranial base have been described. Twenty five males was studied quantitavely by means of serial cephalometric reontgenogram from seven to thirteen years of age. The findings seem to warrant the following conclusions: 1. Growth change in anteroposterior relationship of upper and lower jaws to the anterior cranial base showed very little change before eleven years of age but axial inclination of incisal teeth tended to become labiaization in relation to the anterior cranial base. 2. kiter eleven years of age, there wasn't nearly labialization of incisal teeth but jaw prognathism occurred a little in relation to the anterior cranial base.

The postoperative maxillary cyst develops as a delayed complication after surgical intervention or Caldwell-Luc operation in the maxillary sinus and was also reported that it could occur after Le Fort I osteotomy. This is also called as surgical cliated cyst because of its lining epithelium is usually lined by a pseudo-stratfied ciliated columnar epithelium. This report represents a case of postoperative maxillary cyst which developed within the anterior of maxilla and in association with nasal mucosa 6 years after a Le Fort I osteotomy. In 1989, 26-year-old male complained of his mandibular prognathism and underwent orthogmathic surgery, Le Fort I osteotomy, bilateral sagittal split ramus osteotomy, partial glossectomy.

Transoral vertical ramus osteotomy (TOVRO) procedure can result in a variety of complications. Complications commonly reported include extensive bleeding due to major blood vessel injury, unpredictable fracture, postoperative infection, neurosensory deficit related Inferior alveolar nerve, insufficient osteosynthesis, and temporomandibular joint problem. The authors describe a case of partial necrosis of the mandibular proximal segment following TOVRO, a rarely reported complication. A 37-year-old otherwise healthy woman underwent Lefort l osteotomy and TOVRO to correct mandibular prognathism. Postoperatively, she developed pain and swelling in the right submandibular region and was found to have a partial necrosis of proximal segment.
