Synchronous ossifying fibromas of maxilla and mandible.

Ossifying fibroma is a benign neoplasm composed of fibrocellular tissue and mineralized material of varying appearance, which is most commonly seen in the posterior region of the mandible as a solitary lesion. We report an unusual case of synchronous ossifying fibroma of maxilla and mandible. To the best of our knowledge, only 13 similar cases have been previously reported.

Pilot study comparing the diffusion of two formulations of botulinum toxin type A in patients with forehead hyperhidrosis.

Background: Different formulations of botulinum toxin type A (BoNTA) may have different diffusion characteristics.

Objective: The objective was to compare the diffusion characteristics of two formulations of BoNTA.

Materials And Methods: A total of 20 patients with forehead hyperhidrosis received four injections of BoNTA in their forehead (one medial and lateral injection of one formulation randomly assigned to one forehead side, one medial and lateral injection of the other formulation to the other forehead side).
