Background: Oral submucous fibrosis (OSMF) is a doubtlessly malignant disorder of the oral cavity. The surgical control of this situation involves excision of the fibrotic bands and interpositional grafts to keep the elevated oral opening. Various strategies and graft had been utilized with differing achievement rates. Aims and Objective: Through this study, an attempt was made to evaluate the efficacy of collagen membrane as wound dressing material for mucosal defect in oral submucous fibrosis. Materials and Methods: The study include 30 patients in the age group of 15 to 60 years with stage III or IVa of oral sub mucous fibrosis all of which underwent operation under general anesthesia to enhance their mouthopening by fibrotomy of bands and placement of collagen membrane by same surgeon. After surgery all the patients were accessed under parameter like hemostatic effect, pain relief, granulation tissue formation, epithelization, contracture and reactivity. All patients were given similar prescriptions for pain killer, antibiotics and postoperative instructions. All patients were examined postoperatively. Results: In this study various parameter were accessing the efficacy of collagen membrane on wound defects were recorded. In this 1st parameter hemostatic 28 patients had a score of good (93.3%) with bleeding stopping within 5 minutes after application of membrane and only 2 patients had a score of fair (6.66%). In pain relief analgesics were stopped on the day of 3rd after procedure 16 patients had a good (53.3%) score, 12 patients had a fair (40%) score while only 2 patients gad a poor (6.66%) score. All the patients had sufficient granulation tissue formation of entire wound therefore all the patients had score of good (100%) at the end of two weeks. Epithelization was noted in 28 patients who had score of good (93.3%) after 1 month. Contracture of the wound site at the end of 3 months were noted and rated as good in 20 patients (66.6%) while fair (33.3%) in 10 patients. No reactivity of any form was found in any of the subjects (100%). Conclusion: In our study we noticed that collagen membrane was found to be very effective in all the subjects and it provided us satisfactory results as intraoral wound dressing material.
An immediate denture is a prosthesis placed immediately following tooth extraction due to esthetic reason. It is used to enhance esthetics, protect extraction related surgical wound and provide function during healing. This type of transitional denture is often associated with a larger number of teeth being extracted on the day of prosthesis insertion and a higher degree of unpredictability relative to anticipated healing. Consequently, the required treatment addresses an immediate denture that will ultimately be transitioned into a denitive prosthesis.
Background: Surgical access to the temporomandibular joint (TMJ) and zygomatic arch is a challenge even to the experienced maxillofacial surgeon. The conventional subfascial approach to these structures carries the potential risk of transient paralysis of the frontalis and orbicularis oculi muscles. 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 facial nerve and thus, is the safest method to avoid facial nerve injury. Aims and Objective: To assess facial nerve injury (FN) following TMJ surgery using deep Subfascial approach and measuring it on House and Brackman facial nerve grading system (HBFNGS). Materials and Methods: A randomized study was performed from August 2013 to March 2017 on 24 patients with unilateral and bilateral TMJ ankylosis. All patients were evaluated objectively for facial nerve injury using with house and brackmann facial nerve injury grading system post-operatively and subjectively inthe various time periods, i.e. 24 hours, 1 week, 1month, 3 months and 6 months. Results: Brackmann facial nerve grading system at 24 hours post operatively– in the deep subfascial approach group, 91.7% of patients (23 cases) had Grade 1 injury and 8.3% (1case) had Grade 3 injury. The condition improved with time with full recovery of facial nerve injury (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 thesafest method to avoid injury to facial nerve injury (FN).
