Giant Osteoma of Zygoma Mimicking Pseudo-Temporo-Mandibular Joint Ankylosis: A Case Report.

Giant osteoma is a rare entity in the head and neck region when compared to long bones. Even in the head and neck region, the paranasal sinuses are commonly associated, but the involvement of jaw bones is very rare. The lesions are usually asymptomatic and so remain undiagnosed for years.

Is 0.75% ropivacaine more efficacious than 2% lignocaine with 1:80,000 epinephrine for IANB in surgical extraction of impacted lower third molar?

Purpose: We aim to compare and evaluate the anesthetic efficacy and safety of inferior alveolar nerve block (IANB) using 0.75% ropivacaine and 2% lignocaine with 1:80,000 epinephrine in lower impacted third molar (LI3M) surgery.

Patients And Method: We designed a prospective randomized, double-blind, split-mouth study evaluating 60 systemically healthy patients with the presence of bilateral symmetrically oriented LI3M.
