Osteochondroma of the mandibular condyle.

Osteochondroma (OC) of the mandibular condyle is a relatively rare condition that causes a progressive enlargement of the condyle, usually resulting in facial asymmetry, temporomandibular joint (TMJ) dysfunction, and malocclusion. Radiographically, there is a unilaterally enlarged condyle usually with an exophytic outgrowth of the tumor from the condylar head. We present a case of a left mandibular condylar OC that created a major facial asymmetry, malocclusion, and TMJ dysfunction.

Buprenorphine with bupivacaine for intraoral nerve blocks to provide postoperative analgesia in outpatients after minor oral surgery.

Purpose: The demonstration that opioid receptors exist in the peripheral nervous system offers the possibility of providing postoperative analgesia in the ambulatory surgical patient. Over the previous decade, many investigators have studied this approach and have compared the efficacy of various opioids added to the local anesthetic near the brachial plexus; and it appears from several of these studies that buprenorphine provides the longest duration of analgesia, the most important parameter of postoperative analgesia in outpatients. One of these studies indicated that the agonist-antagonist, buprenorphine, added to bupivacaine provided a longer period of postoperative analgesia than the traditional opiates, but none of the studies was performed in patients undergoing minor oral surgery to check the efficacy of buprenorphine to provide postoperative analgesia in dental patients.
