congenital deformities. In this report, one method of three dimensional reformatting is reviews. Images formed by this method have solid surface appearance and can be color enhanced and manipulated to isolate anatomic structures of interest. The program allows tissue densities, volumes, and distances. This report emphasizes maxillofacial applications other than those previously reported in the surgical and radiological literature.]]>

surgery. In this study,the Photoshop program was introduced to simulate the surgical result. The purpose of the study was to evaluate reliability of the program in prediction of profile changes as a result of mandibular set-back surgery. Based on predicted hard tissue changes, soft tissue changes were recorded with pre-and postoperative lateral cephalogram of 26 patients with skeletal Class III deformity. All patients underwent bilateral sagittal split osteotomy.The mean mandibular set-back was 6.2mm (Pog)and soft tissue moved 6.3mm,100%in Pog'point post-operatively.Difference between the between real horizontal soft tissue changes and predicted changes has not been detected statistically.However,the result revealed vertical soft tissue profile prediction was unsatisfactory.This prediction method can be used as additional informative tool for the patient explanation.]]>

4.Changing Paradigms in the Treatment of Radial Club Hand: Microvascular Joint Transfer for Correction of Radial Deviation and Preservation of Long-term Growth.

Radial longitudinal deficiency, also known as radial club hand, is a congenital deformity of the upper extremity which can present with a spectrum of upper limb deficiencies. The typical hand and forearm deformity in such cases consists of significant forearm shortening, radial deviation of the wrist and hypoplasia or absence of a thumb. Treatment goals focus on the creation of stable centralized and functionally hand, maintenance of a mobile and stable wrist and preservation of longitudinal forearm growth. Historically centralization procedures have been the most common treatment method for this condition; unfortunately centralization procedures are associated with a high recurrence rate and have the potential for injury to the distal ulnar physis resulting in a further decrease in forearm growth. Here we advocate for the use of a vascularized second metatarsophalangeal joint transfer for stabilization of the carpus and prevention of recurrent radial deformity and subluxation of the wrist. This technique was originally described by the senior author in 1992 and he has subsequently been performed in 24 cases with an average of 11-year follow-up. In this paper we present an overview of the technique and review the expected outcomes for this method of treatment of radial longitudinal deficiency.

Objective: Our aim of this study is to describe the outcomes of a series of patients who underwent cleft repair and posterior cartilage grafts laryngotracheoplasty (LTP) from anterior midline cervical approach for type Ⅲ laryngotracheoesophageal clefts (LETC). Methods: A review of patients with type Ⅲ LETC between May 2017 and December 2021 was performed. Demographic features including gender, age at surgery, weight, airway support, feeding status, and airway and other comorbidities were collected preoperatively. Patients were evaluated in breathing, swallowing and phonation postoperatively. The developmental status and morbidities were recorded. Results: Five patients who underwent cleft repair and posterior cartilage grafts LTP from anterior midline cervical approach were included. All patients survived and thrived postoperatively. At last follow-up, 3 patients were able to successfully extubate with acceptable voice, and 2 patients were tracheostomied. Four patients were able to be fed orally without aspiration, and one patient needed to be fed by thick food. Conclusion: The combination of cleft repair and posterior cartilage grafts LTP from anterior midline cervical approach is an effective and safe treatment for type Ⅲ LETC.

Clinical features of 1 case of retroperitoneal parasitic fetus (PF) were retrospectively analyzed and Chinese literatures were reviewed. PF in China has 4 clinical features: 1) The incidence was extremely low and it was more common in infants and children. 2) The parasitic parts showed centrality. 3) The retroperitoneum and abdominal cavity were the most common parasite locations. 4) There was no gender difference in the incidence. Retroperitoneal PF should be distinguished from various benign and malignant abdominal tumors. Imaging was the optimal option for PF diagnosis and the axis bone system was its typical manifestation. Complete excision was the optimal treatment. Thick and large nutrient vessels may be found at where the placenta was attached, and should be ligated carefully. The outcome of this case was good because PF was completely excised.

8.Roentgraphic Cephalometric Standard for Maxillofacial Normals with Ideal Occlusion in Korean Adults.
Yeungnam University Journal of Medicine 1989;6(1):141-149
The purpose of this study was to aid the case analysis and diagnosis of the maxillofacial deformities for orthognathic surgery. The applied method for analysis was a Cephalometrics Orthognathic Surgery (COGS) by Burstone. Lateral cephalograms werer obtained from 59 subjects over 21 years old, that consisted of 30 males and 29 females with normal occlusion, acceptable profile. The results were as follows: 1. The author made the tables of means, standard deviations in each item, sex. 2. The author performed whether there was significance (P<0.05) between the registered male and female's measurement in each item.

Nasal fractures are the most common type of facial fractures. Nowdays computed tomography is found to be very helpful in diagnosing nasal fracture, especially in findings the nasal septal fractures. From August 2004 to July 2005, 36 cases of nasal fracture were admited and reviewed to oral and maxillofacial surgery of Ulsan University Hospital, not including other facial bone fracture. Out of 223 cases of facial bone fractures, we treated 47 cases of nasal fractures. We reviewed and examined the 36 patients of nasal fractures 2months postoperative. The results were 28cases of male and 8cases of female. The highest age frequency was in the fourth decades group. The most frequent causes of injury were falling down and fist trauma. The 25(69%) patients were found to have septal fractures, after computed tomography findings. The treatment methods of nasal fracture were closed reduction(13cases), open reduction(20cases), ORIF(1case), non operation(2cases). Complications of nasal deformity were found in 2patients. Septoplasty was performed on 21 patients. Septal fractures in combination with nasal fracture are usually unrecognized and untreated at the time of injury, usually ended in nasal deformities. It is important to find out the exact type of nasal fractures. We will report the results of treatment of nasal fractures with a literature review.

We observed 469 cases (male 217 cases, female 252 cases) with dento-facial deformity for 10 years from Jan 1994 to Dec 2003. The ratio of male to female was 1:1.2 and the mean age was 23.3 years (male 24.0 years, female 22.6 years) ranged from 11 to 43 years.1) The most dominant group was related to mandibular prognathism (80.4%). A rate of 83.8% demonstrated mandibular protrusion according to Slavicek's classification (n=160), and 85.4% were classified as skeletal Class III type according to Sugawara's classification (n=151) Surgical method were divided into 355 cases of one jaw surgery (single method), 26 cases of one jaw surgery (combined method), and 77 cases of two jaw surgery. Sagittal split osteotomy were performed on 316 cases (69.0%). The average operation time and blood loss in SSRO were 4.1 +/- 2.2 hrs. and 138.8 +/- 222.6 ml (n=152)
