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.]]>

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.

BACKGROUND: The transposition flap is one of the most useful methods of facial reconstruction after Mohs micrographic surgery of the basal cell carcinoma, but occasionally some variations are needed. OBJECTIVE: We present our experience with several variations of the transposition flap to overcome the disadvantages of classic rhomboid flaps. METHODS: We performed the Webster 30-degree angle flap on the lower eyelid, the double 30-degree angle flap on the temple area and the nasolabial flap on the ala nasi. RESULTS: These variations of the transposition flap gave no complications such as ectropion, tissue distortion, protrusion, or trapdoor deformity. CONCLUSION: The variations of the transposition flap in our cases might be of help in selecting the ideal method in facial reconstruction.

After bimaxillary orthognathic surgery for correction of facial deformity, the factors influencing stability of bone segment are the amount of bone segment, surgical technique, fixation technique, rotation of proximal segment. The aim of this study is to analyze the significance of the factors influencing skeletal relapse after bimaxillary orthognathic surgery. From March 1994 to march 2003, 11 patients who underwent bimaxillary procedures without genioplasty or any other orthognathic surgical procedures were included for sample. Lateral cephalograms were analyzed before surgery, 1 month and 12 months after surgery respectively. Vertical, horizontal, angular and dental measurements were obtained from each tracing using the horizontal and vertical reference lines. The mean amount of bone movement and relapse was 7.03mm, 2.44mm (35%) respectively at pogonion and 3.41mm, 0.6mm (18%) respectively at point A. After statistical analysis of collected data, the amount of skeletal movement, fixation technique were significantly related to relapse, but rotation of proximal segment, surgical procedures were not significantly related to relapse. Then we suggest that when operation is planned, 20-30% overcorrection was recommended at the time of bimaxillary surgery.

Although orthognathic surgery has been performed at the maxilla and the mandibular ramus to obtain a normal functional occulsion and aesthetic improvement of the face, deformities of the chin and disproportion of the soft tissue have been left. Mandibular set-back or advancement usually leaves soft tissue redundancy or deficiency along with its displacement. We have combined genioplasty with orthognathic surgery after intermaxillary fixation through a separate incision to get aesthetic improvement in the chin area in 28 patients. The authors obtained the aesthetic profile of the chin and lower lip according to various soft tissue analysis as follows: 1) The depth of the mentolabial fold 2) The distance from the E-line to labrale inferius (LI) 3) N-ANS/ANS-Me The soft tissue disproportion and residual deformities which were not usually corrected by the orthognathic surgery alone could be improved by combining it with genioplasty.
