Background Benign osteoblastoma is a rare tumor of bone representing less than 1% of all tumors of the maxillofacial region. There is a slight predilection for the mandible. More frequent sites for this tumor are the vertebral column, sacrum, long bones, and calvarium. A small predilection in males exists. The age of occurrence ranges from 5 to 37 years, with an average of 16.5. Clinically, patients have pain and swelling. The tumor contains a wellvascularized, osteoblastic connective tissue stroma. Osteoclasts may also be present. Osteoid with varying degrees of calcification, as well as immature bone, is noted. Case report Very few cases of osteoblastomas occurring in the jaws have been reported in the literature. This is one such a rare case report of OB occurring in a 45 year old female patient with a swelling in right lower back region since 5 years. Summary and conclusion Osteoblastoma has to be differentiated from other bone lesions for correct diagnosis. Many bone producing lesions possess some overlapping clinical, radiographic or histopathological findings similar to osteoblastoma. Understanding and correlating all these features is of utmost importance. This helps in correctly diagnosing and helps in adequate management of this rare entity, giving a good prognosis.

Purpose To evaluate the incidence and recovery of persistent sensory disturbances of the infraorbital (IO) nerve after isolated zygomatic complex fractures with various treatment methods. Methods and ResultsThe study was inclusive of isolated unilateral zygomatic complex fractures and fractures of IO rim .Tests performed were Pin prick and Electrical detection threshold test. The evaluation was done preoperatively, after 1 month and after 6 months of surgery. The results suggested that neurosensory disturbance was present in all the patients with zygomatic complex fractures. At 1 month post-operatively some sensory deficit was present in all the patients on the affected side. After 6 months all the patients showed near to normal improvement comparable to normal side. Conclusion Study shows that earlier the surgical intervention, more the recovery of the nerve injury is appreciable during the 1 and 6 months follow up period.

There were 5800 OPGs examined, out of which 2576 were of women and 3224 were of men. Bifid mandibular canals were observed in 135 (2.3%) out of 5800 digital panoramic images. There was no statistically significant correlation found with regard to age. Bifid mandibular canals were found with a female-to-male ratio of 1:1.2. The most frequently encountered type of BMC was type II (1.34%) followed by type I (0.72%), type IV (0.15%), and type III (0.1%).
