Butorphanol/diazepam compared to meperidine/diazepam for sedation in oral maxillofacial surgery: a double-blind evaluation.
Butorphanol and meperidine, each combined with titrated diazepam, 10 to 20 mg, were compared in a randomized, double-blind trial for their sedative-analgesic effects. The fifty patients underwent multiple dental extractions under local anesthesia and sedation in an outpatient clinic. Butorphanol was significantly superior to meperidine with respect to the diazepam dose required to achieve the target level of sedation, the total diazepam dose administered, the clinical level of sedation, the surgeon's overall evaluations of effectiveness and of sedation level, and several patient evaluation parameters measured at discharge from the recovery room and at follow-up interview. All study drugs were well tolerated. Butorphanol offers clinical advantages over meperidine when combined with diazepam for sedation analgesia in outpatient oral surgery.
Equipment failure during mandibular staple bone plate insertion and a technique to resolve it.
Fracture of the set screw on the drill guide used for placement of the mandibular staple bone plate resulted in inability to remove the apparatus. The problem was resolved by cutting the director rods.

Ludwig's angina: report of two cases and review of the literature from 1945 to January 1979.
Two cases of Ludwig's angina treated successfully led us to review the main English language literature from 1945 to January 1979. The most common cause of Ludwig's angina is dental, and the organism cultured most often is streptococcus. However, other avenues of infection and numerous pathogens have been implicated in this disease. Penicillin remains the preferred primary antibiotic, with combinations of this drug and other antibiotics being used by various authors. In both the pre-antibiotic and antibiotic era, the airway remains the prime concern of the surgeon in the management of this potentially life-threatening disease. Of the 75 cases reviewed, there were seven deaths, but four of these patients had pre-existing fatal systemic problems and Ludwig's angina was not the cause of death. The other three deaths were due to Ludwig's angina, yielding a 4% mortality rate. Thus, aggressive management of Ludwig's angina, with respect to airway, antibiotics, and early surgical intervention, has resulted in a significant drop in the mortality rate of this disease which once led "almost uniformly to a fatal ending."
Occlusal acrylic index used to observe palatal bone cuts.
The use of an acrylic occlusal index prior to wiring a full palatal coverage splint into place offers an easy way to check for "hang-up" areas and help in placement of bone grafts while the segments are held in the predetermined position.
