The aim of the present study is to analyze retrospectively the clinico-pathological characteristics of the 220 KCOTs cases in 181 and find the relationship among the various factors. And the following data were obtained: patient age ranged from 8 to 77 years with an average of 33.06 years. There were 111 male and 70 female patients. The mandibular angle and ascending ramus was the most frequent site of KCOTs. Swelling, the most presenting sign, was noted in 97 cases, followed by the pain, 85 cases, and 78 cases showed no presenting signs and symptoms. On radiologic findings, the primary KCOTs appeared as a unilocular in 59 cases or multilocular in 39 cases. The KCOTs can achieve the size of which may vary from 1.0cm to 13.0cm, and the mean size was 4.07cm. The KCOTs were associated with the displacement of impacted teeth, the mandibular third molar; 47 cases, was the most frequent impacted teeth. Four patients (2.21%) were confirmed to be associated with nevoid basal cell carcinoma syndrome. Enucleation or curettage was the most common employed treatment modality (164 cases), followed by marsupialization or decompression (17 cases), and lateral decortication (13 cases). The recurrence rate was 10.78%. Most of the recurrences (21 cases) were found during the first 5 years after the first treatment for the KCOTs.</p></div>","PeriodicalId":100128,"journal":{"name":"Asian Journal of Oral and Maxillofacial Surgery","volume":"23 3","pages":"Pages 117-121"},"PeriodicalIF":0.0,"publicationDate":"2011-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ajoms.2011.03.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87478231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, if there is significant maxillary dentoalveolar protrusion associated with midface hypoplasia, the use of Le Fort III osteotomy alone for midface advancement will result in a poor facial aesthetic outcome. We have recently published a new treatment strategy of correcting this form of deformity by a combination of simultaneous Le Fort III and Le Fort I osteotomies for non-syndromic cases. We would like to report a case of 16-year-old girl presenting with Crouzon syndrome with orbital proptosis, which is caused by a combination of zygomatico-naso-maxillary hypoplasia, as well as maxillary and mandibular dento-alveolar hyperplasia. A combined orthognathic surgical procedure of simultaneous Le Fort III and Le Fort I osteotomies were performed to correct the midface hypoplasia and maxillary dentoalveolar protrusion, while the mandibular dentoalveolar hyperplasia was corrected by a mandibular sub-apical osteotomy. The operation went uneventfully with 10mm advancement of the midface achieving eye protection, occlusal correction and significant facial aesthetic improvement. At 12 months post-operatively, the aesthetic and occlusal results were stable and the patient was very pleased with the clinical outcome. This case was performed in collaboration between the Oral Health Division, Ministry of Health Malaysia and the Faculty of Dentistry, The University of Hong Kong. The report illustrates the clinical outcomes of the simultaneous Le Fort III and Le Fort I osteotomies for the correction of midface hypoplasia and maxillary dentoalveolar protrusion presenting in a Crouzon syndrome patient.</p></div>","PeriodicalId":100128,"journal":{"name":"Asian Journal of Oral and Maxillofacial Surgery","volume":"23 3","pages":"Pages 128-133"},"PeriodicalIF":0.0,"publicationDate":"2011-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.ajoms.2011.04.002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74351359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The significance of the stratification of the GH muscle could be related to the physiological role of the muscle of elevating the larynx during deglutition. Additionally, GH is an important muscle which is preferably preserved in procedures such as mandibulotomy. The presence of this unusual constitution of GH muscle could possibly alter the steps of this operational procedure. While performing routine educational dissection, the suprahyoid region displayed a rare bilaminar constitution of the Geniohyoid (GH) muscle bilaterally. The configuration of Geniohyoid muscle revealed stratification into two layers or lamina, superficial and deep.

On the other hand, with IR, tooth fracture may occur while extracting the tooth if the root is curved or if the buccal cortical bone is particularly thick. To help minimize such risk, we chose IR with partial osteotomy performed on the buccal side of the left maxillary first molar and extraction of both the alveolar bone and the tooth. Osteotomy enabled the tooth extraction without causing damages such as fracture to the roots and offered partial protection of the periodontal ligament.
