A comparative evaluation of iliac crest bone graft with and without injectable and advanced platelet rich fibrin in secondary alveolar bone grafting for cleft alveolus in unilateral cleft lip and palate patients: A randomized prospective study.

PURPOSE: Platelet rich fibrin enhances bone healing and results in better graft intake and helps in faster periodontal healing. In this study we have used a combination of two newly developed forms of platelet rich fibrin: injectable and advanced along with iliac bone graft for secondary alveolar bone grafting and compared it with cases in which only iliac bone graft was used. METHODS: 30 patients with alveolar cleft, with age group of ≥7 years, having complete unilateral cleft alveolus were included and divided into 2 groups of 15 patients each randomly. In Group A, secondary alveolar bone grafting was done using iliac bone graft along with injectable and advanced palate rich fibrin and in Group B, secondary alveolar bone grafting was done only with iliac bone graft. Success of the treatment was assessed using radiographic and clinical methods which included: The bone resorption of the interalveolar septum height of the teeth adjacent to the cleft, evaluated as per Bergland classification, assessment of periodontal status of the teeth adjacent to cleft alveolus. RESULTS: After 3 months and 6 months postoperatively: study group had better overall scores as per Bergland criteria. Periodontal status improved in both groups but was more in study group compared to control group. For both evaluations the data was clinically favorable in the study group. CONCLUSION: On preliminary investigations it shows that combination of injectable and advanced platelet rich fibrin seems to enhance bone formation in alveolar clefts when admixed with autologous cancellous bone harvested from the iliac crest than using iliac bone graft alone. It also reduces the chances of bone resorption and show higher percentage of bone volume. Secondary alveolar grafting improves periodontal health around the cleft alveolus.

Evaluation of the Sternoclavicular Graft for the Reconstruction of Temporomandibular Joint After Gap Arthroplasty.

INTRODUCTION: Ankylosis may be defined as the fusion of the articular surfaces with bony or fibrous tissue. The treatment of temporomandibular joint ankylosis poses a significant challenge because of the high incidence of recurrence. A number of interpositional materials have been used including alloplastic materials (acrylic, proplast-teflon, silastic), and autogenous tissues (temporalis muscle flaps, buccal fat pad, dermis, costochondral grafts, metatarsal, fibula, tibia, iliac crest, cranial bone and Sternoclavicular graft SCG and cartilage). Literature suggests that rather than growth centre, we need adaptive centre. SCG is presumed to be a more suitable material for interpositional arthroplasty because Sternoclavicular Joint (SCJ) and TMJ are very similar developmentally, histologically and morphologically throughout the growth period. MATERIAL AND METHOD: Patients with TMJ ankylosis (8 males, 2 females) underwent release of the ankylosed joint by the senior author, between June 2013 and Novemeber 2015. The age of the patients ranged from 10 to 19 years. Pre- and post- operative assessment included a thorough history and physical examination to determine the cause of ankylosis, the maximal incisal opening, etiology and type of the ankylosis, recurrence rate. RESULT: MIO at 6 months follow up was 37.4±2.633 mm (range 32-40 mm), greater than MIO achieved in immediate postoperatively {34.4±2.22 mm (range 30-38 mm). After reconstruction of temporomandibular joint with sternoclavicular graft in the growing child there was a significant increase in the growth of mandible which was stunned due to ankylosis. And the ramal height also increased. CONCLUSION: The articular reconstruction with alloplastic or autogenous grafts, or gap arthroplasty for the treatment of ankylosis is shown to be efficient in relation to the post-operative maximal incisal opening, recurrence and articular function.

Evaluating the use of octyl-2-cyanoacrylate in unilateral cleft lip repair.

BACKGROUND: Facial cosmetic results are one of the most concerning issues for the parents who get their children operated for cleft lip. Moreover, the postoperative care of the surgical site, the discomfort associated with the suture removal, and additional visit for suture removal are other reasons which encourages one to use any new technologies that may replace the need for suture placement. In this study, we used octyl-2-cyanoacrylate, a tissue adhesive which offers a viable alternative to traditional techniques without compromising optimal wound closure. OBJECTIVE: To perform a comprehensive comparison of the outcomes from the use of Dermabond in patients undergoing primary repair of congenital cleft lip ± palate anomalies. MATERIALS AND METHODS: Twenty patients, in the age group of 3-18 months were treated surgically for unilateral cleft lip deformity using Millard rotation-advancement flap. Pre- and post-operative photographs of the patients were taken at 1 week, 2 week, 1 month, 6 months, and 1 year postoperatively and were evaluated using Vancouver scar scale which was given by Sullivan in 1990. Paired t-test was used for statistical analysis. RESULTS: Increased vascularity (hyperemia) was seen in the 1st and 2nd week in 35% and 30% patients, respectively which gradually reduced to normal in subsequent follow-ups. The scar was flat in 85% of patients in 1st week, and the number decreased to 10% at the end of 1 year. No wound dehiscence was found in any patients. Statistical analysis showed that among all the follow-ups, only the difference between the first and second follow-ups. Comparison of the results of 1 week with all other follow-ups yielded no significant results. CONCLUSION: Octyl-2-cyanoacrylate can be used for cleft lip closure effectively. The procedure is relatively painless and quick. Added to this are benefits of protection from wound infection since the material is bacteriostatic.

Assessment of facial nerve injury with "House and Brackmann facial nerve grading system" in patients of temporomandibular joint ankylosis operated using deep subfascial approach.

BACKGROUND: Preservation of the functional integrity of the facial nerve (FN) is a critical measure of success in temporomandibular joint (TMJ) surgery. In spite of the development of a myriad of surgical approaches to the TMJ, FN remains at risk. The deep subfascial approach provides an additional layer of protection (the deep layer of the temporalis fascia and the superficial temporal fat pad) to the temporal and zygomatic branches of the FN and thus, is the safest method to avoid FN injury. OBJECTIVES: To assess FN injury following TMJ surgery using deep subfascial approach and measuring it on House and Brackman facial nerve grading system (HBFNGS). MATERIALS AND METHODS: Twenty TMJs in 18 patients were operated for TMJ ankylosis, using "the deep subfascial approach." FN function was assessed postoperatively at 24 h, 1 week, 1 month, 3 months, 6 months using HBFNGS. Statistical analysis was done using SPSS 16.0. RESULTS: Of 20 surgical sites 3 sites showed Grade III (moderate) FN injury and 17 sites showed Grade II (mild) FN injury at 24 h. The condition improved with time with full recovery of FN at all surgical sites at 6 months. CONCLUSION: The deep subfascial approach has a distinct advantage over the conventional approaches when dissecting the temporal region and is the safest method to avoid injury to FN.

Esthetic correction of depressed frontal bone fracture.

Depressed frontal bone fractures are occasionally seen in maxillofacial trauma patient. If untreated, they look un-esthetic. Although there are numerous options available for correction of these defects, use of bone cement (polymethylmethacrylate or PMMA) is simple and reliable. This is the report of one such case.
