Maxillary duplication is a kind of proliferative neurocristopathy and considered to arise from bifurcation of neural crest elements soon after migration into mandibular arch. Sometimes this malformation is accompanied with oblique facial cleft. Usually this type of maxillofacial malformation requires multiple surgical intervention and the results are far from ideal. It became more troublesome if it had not been properly corrected on time, because secondary deformities could be developed from growth and development of abnormal tissues. This is a case of a 25-year-old-female patient who showed severe facial asymmetry thought to secondary deformity of maxillary duplication and masticatory disturbance due to multiple supernumerary teeth on posterior part right maxilla. We successully treated these deformities through four times of surgery of bone resection, orthodontic treatment, zygomatic and orbital reconstruction, orthognathic surgery and scar revision... ect. So we reported this rare case with review of literatures.

Recently the goal of orthognathic surgery has been focused on esthetic improvement of the patients. Also early corrective surgery was favorable selected by most of the oral and maxillofacial surgeons. We should consider the etiologic factor of the patient's dentofacial deformities when treatment is planned, because this is the major factor in estimating the predictability or stability of result. The more researches were carried on the etiologic factors of the dentofacical deformities, The more possibility of the early surgical correction will be increased. The authors analyzed about etiologic factors and epidemiologic studies of the forth patients who had received the orthognathic surgery. The analyzed results were as follows: 1. The predilection ration between male and female was 17:23, and 32 patients (80%) of 40 patients were aged twenties. 2. 26patients(65%) complained estetic problems as well as functional problems. 10 patients(25%) complained only esthetic problems, and 4 of 40 patients complained only functional problems. 3. Mandibular prognathism was found to be done most frequently(25, 39%). Facial asymmetry (13, 20%) and angle hypertrophy were found to be next in sequence. 4. Sagittal split ramus ostetomy was done most frequently(27, 35%). Lefort I osteotomy(13, 17%), angle reduction (12,16%), and genioplasty(11, 15%) were done also. 5. The number of the cases due to nonspecific etiologic factor was 22(55%), that of cases due to inhertied tendency was 12(30%), that of cases due to congenital anomaly was 3(7.5%), and that of cases due to trauma was 3(7.5%). 6. The number of patients who got only maxilliary surgery was 2(5%), that of patients who got only mandibular surgery was 23(57.5%), and that of patients who got simultaneous two jaw surgery was 15(37.5%).

Background: Localized scleroderma is characterized by a thickening of the skin from excessive collagen deposits. It is not a fatal disease, but quality of life can be adversely affected due to changes in skin appearance, joint contractures, and, rarely, serious deformities of the face and extremities. We present six cases of localized scleroderma in face from our surgical practice. Methods: We reviewed six localized scleroderma cases that were initially treated with medication and then received follow-up surgery between April 2003 and February 2015. Six patients had facial lesions. These cases presented with linear dermal sclerosis on the forehead, oval subcutaneous and dermal depression in the cheek. Results: En coup de sabre (n=4), and oval-shaped lesion of the face (n=2) were successfully treated. Surgical methods included resection with or without Z-plasty (n=3), fat graft (n=1), dermofat graft (n=1), and adipofascial free flap (n=1). Deformities of the affected parts were surgically corrected without reoccurrence. Conclusion: We retrospectively reviewed six cases of localized scleroderma that were successfully treated with surgery. And we propose an algorithm for selecting the best surgical approach for individual localized scleroderma cases. Although our cases were limited in number and long-term follow-up will be necessary, we suggest that surgical management should be considered as an option for treating scleroderma patients.

Purpose: Most unilateral secondary cleft lip nose deformities have depressed nostril base and sill on the cleft side. To obtain a symmetric nose, correction of the recession on nostril is critical. The authors have worked out effective methods to elevate the nostril of the cleft side according to the extent of the depression. Methods: A total of 115 unilateral secondary cleft lip nose deformity patients with nostril depression were evaluated. Data were acquired from patients' charts and photography with special reference to the height difference of the nostrils between the cleft side and the non - cleft side. Patients were divided into three groups based on the difference and operated with various techniques : (1) mild degree(< 1 mm) with graft, (2) moderate degree(1 ~ 3 mm) with C - flap or suspension suture of septal cartilage (3) severe degree(> 3 mm) with graft, C - flap and suspension suture. Follow - up period averaged 21.3 months. Results: Forty - six patients(40 percent) were in mild group, and forty - two(37 percent) were in moderate. In twenty - seven patients(23 percent), nostril recession was more than 3 mm. The elevated nostril base and sill were maintained without height alteration during follow - up. Conclusion: The symmetry of the nostril base, especially projection of nostril sill influences successful correction of unilateral cleft lip nose deformity. Our tolerable techniques can be applied to most deformities with nostril depression and can present a new guideline.

Background: Patients with advanced asthma and chronic obstructive pulmonary disease (COPD) have postural deviations such as thoracic hyperkyphosis, forward shoulder posture (FSP) due to an increase in head and cervical protraction, reduced shoulder range of motion and a corresponding increase in scapula elevation and upward rotation. Unlike congenital vertebral kyphosis that are permanent and rigid deformities with bony and other structural deformations which cause respiratory impairment, these deformities in these patients may be more flexible. Since the thoracic hyperkyphosis has been implicated as having adverse health consequences it is necessary to evaluated the relationship between thoracic kyphosis and cardiopulmonary functions of patients with COPD and asthma. Methods: It was a cross-sectional analytical study. Eighty-four eligible patients with COPD and asthma were recruited from the Respiratory Unit, Department of Medicine, Lagos University Teaching Hospital (LUTH), and basic anthropometric parameters, pulmonary parameters, cardiovascular parameters, thoracic kyphosis (Cobb) angle and presence of respiratory symptoms of participants were assessed. Data was analyzed using SPSS version 20. Results: There was no significant correlation between the thoracic kyphosis and selected pulmonary parameters (Forced Expiratory Volume in one second (FEV1, p=0.36), Forced Vital Capacity (FVC, p=0.95), Peak Expiratory Flow Rate (PEFR, p=0.16), Thoracic expansion (TE, p=0.27)/cardiovascular parameters (Systolic Blood Pressure (SBP, p=0.108), Diastolic Blood Pressure (DBP, p=0.17) and Pulse Rate (PR, p=0.93) as well as the respiratory symptoms (SGRQ scores, p=0.11) in all subjects. Conclusion: There was no relationship between thoracic kyphosis and selected pulmonary/cardiovascular parameters as well as respiratory symptoms in patients with COPD and asthma.

Background: Patients with secondary deformities associated with unilateral cleft lip and nose might also suffer from nostril stenosis due to a lack of tissue volume in the nostril on the cleft side. Here, we used full-thickness skin grafts (FTSGs) to reduce nostril stenosis and various methods for skin volume augmentation. We compared the changes in the symmetry of both nostrils before and after surgery. Methods: From February 2016 to January 2020, 34 patients underwent secondary cheiloplasty and open rhinoplasty for secondary deformities of the unilateral cleft lip and nose with nostril stenosis. FTSG was used on the nostril floor, nasal columella, and alar inner lining. The measured nasal profile included the nostril surface, nostril circumference, width of the nostril floor, and distance from the alar-facial groove to the nasal tip. The "overlap area," which was defined as the largest overlapping area when the image of the cleft nostril was flipped to the left and right and overlaid on the image of the normal side nostril, was also calculated. The degree of symmetry was evaluated by dividing the value of the cleft side by that of the normal side of each measured profile and expressed as "ratios." Results: The results of all profile ratios, except for the nostril floor width, became significantly close to 1, which represents full symmetry. The overlap area ratio improved from 62.7% to 77.3%, meaning that the length and width of the nostril as well as the overall shape became similar (p< 0.05). Conclusion: When performing cleft rhinoplasty with nostril stenosis, FTSG is useful to achieve symmetry in the nostril size and shape. Skin grafting is simpler to perform than the other types of local flap, and the results are generally satisfactory.

This paper presents our clinical experiences for reconstruction of the linear depressed postburn scar band by rhombus subcutaneous pedicle skin flap (RSPF). We report new RSPF, it's versatility, and effectiveness for correction of the mild to moderate linear depressed postburn scar band. To correct the postburn scar band, we have newly designed the Rhombus Subcutaneous Pedicle Skin Flap (RSPF), which is made as rhombus-shaped skin flap on the inside of scar band. After excision of burn scar band, the each vertex of RSPF flap is advanced into the skin defects at apex of extended skin incision, which is starting from the upper and lower portion of the removed burn scar band at a near right angle. This flap can add more extra skin to adjacent superior and inferior area of excised scar band. We have experienced 2 cases of RSPF for reconstruction of linear depressed postburn scar band deformities in lower extremity. After 3 weeks to 3 months postoperative follow ups, relatively satisfactory results were obtained in all cases. We had successfully reconstructed the linear depressed postburn scar postburn band of lower extremity using the rhombus subcutaneous pedicle skin flap. For the correction of mild to moderate sized linear depressed postburn scar band deformities in extremity, the RSPF is simple, and very effective without donor morbidity.

The face and the external nose define an individual's physical appearance. Nasal deformities can cause facial disfigurement along with unwanted psychological repercussions. Nasal deformities range in severity, with the most severe cases being indications for a rhinectomy, due to the complexity of the nasal defect. According to published literature, there is no consensus among otolaryngologists and plastic surgeons on which technique or flap use is preferred in terms of complications, aesthetic outcome, or patient satisfaction. The goal of this study is to provide a comprehensive analysis of published studies on nasal reconstruction following rhinectomy. Using the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines for writing systematic reviews, a systematic review was conducted. Four databases were searched using a search strategy. These articles were then imported into the COVIDENCE software and went screening and thorough article review. After screening 2,237 articles, 23 studies were then extracted for data collection analysis. We collected data from 12 case series, 4 case studies, 1 prospective case series, and 4 retrospective chart review studies. The most commonly reported flaps were forehead flaps, superior extended nasal myocutaneous island, forearm free flaps, anterolateral thigh (ALT) free flap, medial femoral condyle free flap (n = 8), and zygomaticus implants (n = 6), and retained nasal prosthesis. Although not specifically indicated by a certain number, the most common indication for the rhinectomy was malignancy, followed by traumas, postsurgical complications, radionecrosis, and congenital nasal malformations.

Objective: This study aimed to present and evaluate a new deep learning model for determining cervical vertebral maturation (CVM) degree and growth spurts by analyzing lateral cephalometric radiographs. Methods: The study sample included 890 cephalograms. The images were classified into six cervical stages independently by two orthodontists. The images were also categorized into three degrees on the basis of the growth spurt: pre-pubertal, growth spurt, and post-pubertal. Subsequently, the samples were fed to a transfer learning model implemented using the Python programming language and PyTorch library. In the last step, the test set of cephalograms was randomly coded and provided to two new orthodontists in order to compare their diagnosis to the artificial intelligence (AI) model's performance using weighted kappa and Cohen's kappa statistical analyses. Results: The model's validation and test accuracy for the six-class CVM diagnosis were 62.63% and 61.62%, respectively. Moreover, the model's validation and test accuracy for the three-class classification were 75.76% and 82.83%, respectively. Furthermore, substantial agreements were observed between the two orthodontists as well as one of them and the AI model. Conclusions: The newly developed AI model had reasonable accuracy in detecting the CVM stage and high reliability in detecting the pubertal stage. However, its accuracy was still less than that of human observers. With further improvements in data quality, this model should be able to provide practical assistance to practicing dentists in the future.

The Poland`s syndrome is very rare anomaly, which consists of congenital unilateral absence of the sternocostal pert of the pectoralis major muscle, with ipsilateral hand deformities. The clinical features are variable but all patients have absence of at least the sternal head of the pectoralis major muscle. The syndrome is not hereditary and is of unknown origin. Early recognition of Poland`s syndrome may give the provision of psychological and genetic counseling for anxious parents. We have encountered a patient with this entity, who showed striking paradoxical movement of the left anterior Ghest wall and recurrent pneumonia, and underwent successful surgical correction.
