ABSTRACT
Schwannoma or neurilemmoma is a neurogenic tumor. Intraoral schwannoma is rare and intraosseous schwannoma involving maxilla is even rare. We present one such rare case of maxillary sinus schwannoma extending to the nasal cavity, infratemporal fossa in a 22-year-old male. Wide excision of the lesion with subtotal maxillectomy of the right side was done using Weber-Fergusson approach. The patient made a good postoperative recovery. The relevant literature on the presentation, radiology, and management of schwannoma of maxillary sinus is discussed.
ABSTRACT
BACKGROUND: To evaluate the effects of intraalveolar placement of gel containing 0.2% chlorhexidine and 10gm of metronidazole on the incidence of alveolar osteitis. MATERIAL AND METHODS: A total of 300 impacted third molars were extracted in 150 patients enrolled in this trial. In each subject a socket was randomly selected and packed to the crest of alveolar ridge with the gel. The contralateral socket was packed with placebo dressing. The occurrence of dry socket was assessed during 3rd and 5th postoperative days .The data was analysed using a meta analytical program. STUDY DESIGN: Double blind, prospective, placebo controlled trial. RESULTS: The combination of metronidazole + chlorhexidine gel significantly reduced dry socket incidence from 22.6% to 6.6% (P ≤ 0.001) [McNemar and chi-square tests]. CONCLUSIONS: The decrease in incidence of adverse reactions and complications related to local application of metronidazole and chlorhexidine gel explains its clinical use, specifically in mandibular molar extractions where the chances of dry sockets are high. Key words:Chlorhexidine, dry socket, intra-alveolar, metronidazole, placebo.
ABSTRACT
Temporomandibular Joint (TMJ) ankylosis is a situation in which the mandibular condyle is fused to the glenoid fossa by bone or fibrous tissue. The management of TMJ ankylosis has a complicated chore and it is challenging for the maxillofacial surgeon because of technical hitches and high rate of re-ankylosis. Interpositional gap arthroplasty is one of the modalities for its management. A range of inter-positional materials have been used to avert recurrence after gap arthroplasty in TMJ ankylosis. The aim of this series was to evaluate the effectiveness of the temporomyofacial flap in the treatment of TMJ ankylosis as an interpositional gap arthroplasty. A total of 10 cases with unilateral TMJ ankylosis were treated by interpositional gap arthroplasty by pedicled temporalis myofacial flap and evaluated with a follow-up of 6 months to 5 years (Mean 3.3 years) for the functional stability of TMJ. All the patients were successfully treated. There were no signs of recurrence in any patients up to last follow up visit. The result showed that temporalis myofascial flap is a preferable choice for inter-positional gap arthroplasty which proves its versatility as an inter-positional material.
