Nonfunctioning parathyroid carcinoma.

Lidocaine v bupivacaine in facial plastic surgery. A clinical trial.

The ideal local anesthetic agent for facial plastic surgery should have rapid onset, good surgical anesthesia, and reasonably long duration. The purpose of this prospective, randomized, double-blind study was to compare 1% lidocaine hydrochloride with 1:200,000 epinephrine with 0.5% bupivacaine hydrochloride with 1:200,000 epinephrine, a newer, longer-acting local anesthetic, in different facial operations.

Management of acute alcohol withdrawal.

The relationship between maxillofacial trauma and alcohol abuse has been well documented. The onset of acute alcohol withdrawal following the injury can seriously complicate and compromise the treatment of the maxillofacial injuries as well as be potentially lethal for the patient. A clear understanding of the biochemistry, development, signs and symptoms, and management of acute alcohol withdrawal is necessary for the oral and maxillofacial surgeon.
