The indications must be carefully considered, because some patients benefit from the use of prosthesis. CTA has become an option for amputees so it is important to do more research, to determine the benefits of this procedure. It is not considered a life-saving procedure, so there is an ethical debate because of the risks.
Current knowledge of neurotrophic factors is now revealing the complex control of energy homeostasis and appetite, as well as the crucial role of these factors in nervous system functions. The aim of this study was to assess the serum levels of neudesin in adolescents with obesity and to examine the relationship between these levels and metabolic outcomes.
In total, 88 adolescents aged 10-17 years were enrolled 15 were obese, 43 were morbidly obese and 30 had normal weight (controls). Serum neudesin concentrations compared between the groups.
Neudesin levels were significantly lower in obese adolescents than in the control group (p=0.013). A correlation analysis applied to the whole study group revealed a negative correlation between serum neudesin levels and BMI z scores (r=-0.40, p=0.000). The serum neudesin levels tended to increase in adolescents with metabolic syndrome, insulin resistance, dyslipidaemia, and hypertension but the differences were not statistically significant (p=0.259, p=0.246, p=0.d metabolic disorders should be supported by detailed studies enrolling larger groups.
Ankylosis of the temporomandibular joint (TMJ) is a debilitating condition and disabling as a result of craniomandibular fusion, which can result in trismus, pain and a poor quality of life. Current management includes interposition arthroplasty, gap arthroplasty, and reconstruction. Traditionally, the joints are reconstructed with pre-made prostheses (in stock), or the procedure is performed in two steps; with a computerized tomography scan, its design is observed between the respective and reconstructive procedures.
A technical note about the customization management of ankylosis of the temporomandibular joint.
Describe a modification of technique using 3D surgical cutting and positioning guides digitally created to help determine the position and dimensions of the osteotomies as an auxiliary tool in the management of TMJ ankylosis, enabling the installation of personalized prostheses in a single stage.
This technique has the advantage of allowing the installation of customized TMJ prostheses in a single stage, allowing greater predictability, less surgical time and less morbidity, in addition to being relatively simple and can be easily picked up by young surgeons.

Management of maxilla and mandibular fractures are based on the principles of reduction, fixation and immobilization of the fracture segments.
One of the processes of reduction is to apply continuous and gradual elastic traction by placing elastics from the upper and lower arch bars in a definite manner and direction as per the fracture line. Orthodontic elastic separators are versatile, and the major advantage is the higher traction forces as compared to conventional elastics.
Prestretched separator elastics were guided over the arch bar or fixed orthodontic appliances to provide desired traction.
Orthodontic elastic separators are therefore versatile, and the major advantage is the higher traction forces as compared to conventional elastics. They provide an edge over the use of wires as they tend to break off by work hardening.
Therefore, we have adapted orthodontic separators and have used them in place of conventional elastics for the last 10 years with appreciable results after taking informed consent from the patients.

The objective of this study was to correlate the preoperative radiological findings and intraoperative surgical findings during removal of impacted mandibular 3rd molar with respect to the inferior alveolar canal.
The prospective study design included 100 patients between the age group of 20years and 50years who visited the Department of Oral and Maxillofacial Surgery at Vydehi Institute of Dental Sciences and Research Centre, Whitefield, Bengaluru. A preoperative panoramic radiograph was taken and the parameters were assessed and a normal surgical protocol was followed to extract the impacted mandibular 3rd molar with intra-operative assessment as well.
Out of the 100 patients with definitive radiological signs showing close relation of the third molar to the mandibular canal who underwent surgical removal, only 12 patients presented with definitive clinical findings of the association.
A true close relationship between the third molars and mandibular canal increases the risk of inferior alveolar ner evidence of involvement. Surgeons should be aware of the limitations of the radiographic markers of panoramic radiography and should consider more detailed imaging in more specific cases in which one or more radiographic marker is present.
Nonsyndromic unilateral CLAP patients despite the best surgical efforts present with variable degree of maxillary hypoplasia after cleft palate repair. AMOD is an extension of anterior maxillary osteotomy where the resulting segment anterior to the chosen site of vertical corticotomy cut is distracted with the help of hyrax screw through a tooth-borne appliance.
To analyze the hard and soft tissue profile changes following AMOD. To determine the ratio of soft tissue changes to the given extent of hard tissue movements.
Study group consisted of 25 patients with cleft maxillary hypoplasia reporting to the Department of OMFS, Coorg Institute of Dental Science. The preoperative and postoperative radiographs were taken followed by prediction tracing. In comparison of pre-op and post-op ceph mean improvement in hard tissue profile was seen at N-A by 2.84mm, N-A-Pg by 2.52, ANS-Gn by 2.28mm, N-ANS by 0.68mm, 1-Nf by 0.32 and at PNS-ANS was 4.2mm signifying improvement in middle third of face. Mean improvement in soft tissue profile at G-Sn-Pg angle by 1.2, G-Sn was 3.92mm, nasolabial angle by 10.92, incisor exposure (Stm-1) by 0.24mm and interlabial gap by 0.56mm. On ratio and correlation of soft tissue changes to given extent of hard tissue change, with movement of point A and U1 resulted significant changes in Sn and Ls. Movement of ANS resulted in significant changes in pronasale and columella.
In our study significant improvement was seen in hard and soft tissue facial profile. In conclusion, AMOD is one of the emerging techniques to correct cleft maxillary hypoplasia which will have a defined definitive role to play in future.

To compare treatment outcome of arthroplasty followed by distraction osteogenesis (AFD) and distraction osteogenesis followed by arthroplasty (DFA) in the management of mandibular deficiencies in temporomandibular joint (TMJ) ankylosis.
A total of 20 patients with TMJ Ankylosis were included in the study. Patients were randomly divided into two groups. Group 1 consisted of patients for whom arthroplasty was done prior to distraction osteogenesis (AFD) for the correction of deficient mandible. Group 2 included patients where distraction osteogenesis was performed prior to arthroplasty (DFA). The treatment outcome was assessed based on maximum interincisal distance, overjet, corpus length, ramus height, upper airway, lower airway, duration of the procedure and the complications for the treatment at the end of 3, 6 and 12months.
After the treatment was ended, the patients of both groups had increase in mouth opening and appearance was improved remarkably. There was general increase in all the parameters in both the groups. But at the end of 12months, airway and the ramus height were more stable and the control of the proximal segment was superior in DFA group. Open bite was noticed in 2 cases of AFD group which was treated by elastics. There required additional surgery for the removal of distractors in the AFD Group. Establishing the airway during the surgery was easier in AFD group.
The study concludes that distraction followed by arthroplasty was a better procedure for the management of TMJ ankylosis owing to its stable results and less number of surgeries.

Conservative treatment, including observation and closed treatment, as well as open reduction and internal fixationare existing options for treating condylar process fractures. Extraoral approaches are widely preferred for open reduction and internal fixation. Transoral access for condylar base and neck fractures is not yet commonly used as it is technically demanding and requires special equipment.
In this study, the transoral endoscopically assisted approach is described, and its outcomes and complications were investigated. Imaging data and clinical records of 187 patients with condylar process fractures, treated via endoscopically assisted transoral approach between 2007 and 2017 were analyzed. Parameters included diagnosis and fracture classification, treatment, osteosynthesis configuration and postoperative complications.
Early complications, including infection, transient postoperative malocclusion, pain and limited mouth opening, occurred in 35 patients (18.7%). selleck compound Late onset complications, such as screw loosening were documented in only 4 patients (2.1%). Revision surgery following postoperative 3D imaging was required in only 3 cases (1.6%). Fragment length ranged from 15.5 to 38.3mm. In 57.7% of patients with condylar fragment length < 20mm, a single osteosynthesis plate was used, with no elevated complication rate. Two osteosynthesis plates with 4 screws each was used as standard in longer fragments.
Endoscopically assisted transoral treatment of condylar process fractures is a reliable, yet technical demanding technique. It allows for reduction and fixation of fractures with a condylar fragment length of > 15mm with low postoperative complication and revision rates.
15 mm with low postoperative complication and revision rates.
To investigate a reliable and safe surgical access to the condylar base region with minimal surgical trauma to the surrounding anatomic structures. In an attempt to do so, to describe Infinitesimal Peri-angular Pterygomasseteric Transectioning Approach (IPPTA) for the management of base fractures of the mandibular condyle.
A preliminary clinical study involving 20 patients was undertaken to treat patients with unilateral condylar base fracture of the mandible using IPPTA under general anaesthesia (GA). Various parameters assessed were adequacy of surgical access, wound healing at the incision site, marginal mandibular nerve injury, diet intake and complications post-operatively.
This method provided adequate exposure to fractured condylar base for open reduction and internal fixation (ORIF) with uneventful post-operative recovery phase. There was no limitation to function which was identified by restoration of normal pre-trauma diet intake by 14th post-operative day in more than 50% of the study patients.
