Dermis fat graft has shown good clinical results as an interpositional material in temporomandibular joint (TMJ) ankylosis and prevents heterogeneous calcification following gap arthroplasty. However, survival of the graft and volume retention is still debatable. The main purpose of our study was to assess the viability of the graft, tissues changes associated with the graft and volume retention using magnetic resonance imaging (MRI).

Fifteen patients with TMJ ankylosis underwent gap arthroplasty followed by placement of abdominal dermis fat graft and were randomly divided into two groups. Group 1 was subjected to MRI analysis of the graft at 3-6 months and Group 2 was analyzed at 1-2 years post-operatively. The graft was evaluated using T1- and T2-weighed images along with fat suppression (FS) sequences in all the three planes and the volume was also calculated.

Both Group 1 (7 patients and 11 joints) and Group 2 (8 patients and 13 joints) showed the presence of viable fat on T1 and T2 images, confirmed by FS images. Minor tissue changes were observed at the center of the graft in 5 patients of Group 1 and 3 patients of Group 2. Average volume of the graft was 4.154 cm
at 3-6 months and 4.269 cm
at 1-2 years, respectively, and when compared to the original volume of the graft (4.583 cm
in Group 1 and 4.712 cm
in Group 2), the difference was statistically insignificant (
 > 0.005).

MRI shows long-term survival of autogenous dermis fat graft without significant volumetric reduction. This along with positive clinical results make dermis fat an excellent choice as an interpositional material for TMJ ankylosis.

To evaluate changes in airway dimensions following mandibular setback with conventional orthognathic approach (COA) and surgery-first orthognathic approach (SFOA).

Treatment records of 20 patients who underwent mandibular setback with SFOA/COA were divided into two groups (COA and SFOA, ten patients in each group). Acoustic pharyngometry values were obtained at T0 (01week prior to surgery), T1 (01-month post-surgery) and T2 (01-year post-surgery). Percentage change in mean volume and area was obtained at T1 (T1-T0) to evaluate airway changes and at T2 (T2-T1) to compare relapse of airway changes in both groups. Changes in airway per mm setback at T1 (T1-T0) and T2 (T2-T1) were also obtained in both groups.

For both parameters, SFOA showed greater reduction at T1 and greater relapse at T2 as compared to COA. The reduction in airway volume at T1 was 0.56mm/mm setback in COA compared to 1.06mm/mm setback in SFOA (
-value > 0.05). The relapse in airway volume at T2 was 0.15mm/mm setback in COA compared to 0.25mm/mm setback in SFOA (
-value > 0.05). The reduction in area at T1 was 0.062mm/mm setback in COA compared to 0.110mm/mm setback in SFOA (
-value > 0.05). The relapse in area at T2 was 0.016mm/mm setback in COA compared to 0.034/mm setback in SFOA (
-value < 0.05).

In setback cases, SFOA has greater airway reduction immediate post-surgically and greater relapse at 01-year follow-up. Predicting these changes at diagnostic and treatment planning stage may prevent potential adverse events on airway.

Platelet-rich plasma (PRP) has been a breakthrough in the stimulation and acceleration of bone and soft tissue healing. It represents a relatively new biotechnology that is part of the growing interest in tissue engineering and cellular therapy.

A prospective study was carried out in 50 patients. read more The cases were selected randomly in the age group of 8-50years who needed bone grafts for alveolar cleft defects and surgical defects following removal of osteolytic jaw lesions. They were divided into study group with autologous PRP and control group without PRP. Bone density was calculated as per Hounsfield scale preoperatively and post-operatively for both the groups.

There was significant difference in the Hounsfield units at 06months and 12months post-operatively in both the groups showing good amount of bone regeneration. The preoperative volume of the defect and the post-operative volume of the regenerated bone were statistically analysed. The mean V2 was 0.7652cc for the study group, whereas for controlhe maxillofacial region as shown by the increase in the density of bone.
To evaluate the management of alveolar cleft defects with proximal tibia bone grafts by late secondary alveolar bone grafting.

Fifteen patients were studied, nine males and six females within age range of 21-32years. All the patients were treated with cancellous portion of the proximal tibial bone graft, harvested through the medial approach.

Intraoperatively, sufficient amount of bone was harvested which ranged from 19 to 24ccs (mean 20.7 ccs). In two patients, moderate bleeding had occurred, whereas in remaining patients, mild bleeding was observed. Operative time ranged between 1.25 and 1.50h (mean 1.36h). Infection was reported in one patient (7%), which resolved by the end of one and a half months. Complete elimination of the oronasal fistula was achieved in all cases. Neurosensory disturbance (parasthesia) at the donor site was observed in two patients (13%) from the first postoperative week and subsided within 8 months. Gait disturbance was not reported in any of the cases. However, in two patients (13%), intermittent pain during daily activities remained for more than 2months, which completely resolved by the end of the third month.

Tibial graft is a reliable donor site option for grafting in cleft alveolus for which the advantage being minimal donor site morbidity. The resorption rate of the graft is also minimal in the present study.
