Comparative StudyLong-term study of temporomandibular joint surgery with alloplastic implants compared with nonimplant surgery and nonsurgical rehabilitation for painful temporomandibular joint disc displacement.
The purpose of this study was to determine the long-term objective and subjective outcomes of temporomandibular joint (TMJ) implant surgery for the treatment of painful TMJ disc displacement using temporary Silastic (Dow Corning Corporation, Midland, MI), permanent Silastic, or Proplast (Vitek, Houston, TX) implants to replace the disc. These cases were compared with other cases of the same diagnosis treated with either nonsurgical rehabilitation or nonimplant surgery involving discectomy or disc repair procedures. ⋯ This study suggests that the use of interpositional disc implants in TMJ surgery is not associated with improved outcomes when compared with nonimplant surgery or nonsurgical rehabilitation.

Randomized Controlled Trial Clinical TrialSmall dose of propofol for preventing nausea and vomiting after third molar extraction.
The study goal was to evaluate the efficacy and safety of a small dose of propofol for the prevention of nausea and vomiting following third molar extraction. ⋯ Prophylactic therapy with a small dose (0.5 mg/kg) of propofol is effective for preventing postoperative nausea and vomiting in female patients undergoing general anesthesia for third molar extractions.

Evaluation of computer-based area and volume measurement from coronal computed tomography scans in isolated blowout fractures of the orbital floor.
In this retrospective study, we evaluated isolated blowout fractures of the orbital floor by region-of-interest measurements from coronal computed tomography (CT) scans and their relationship to ophthalmologic findings. ⋯ Region-of-interest measurement from coronal CT scan has an application in the assessment of patients with pure blowout fractures of the orbital floor and adds useful information in posttraumatic evaluation of orbital fractures.

Mechanosensory and thermosensory changes across the border of impaired sensitivity to pinprick after mandibular nerve injury.
The study goal was to determine how sensory function varies across the border of impaired sensitivity to pinprick in patients with mandibular nerve injuries. ⋯ Although certain patients exhibit impairment, there is no obligatory loss in light touch, 2-point perception, direction discrimination, or temperature perception across the border of decreased sensitivity to pinprick. The differences among patients suggest that the data from individual patients should be evaluated in clinical studies and in clinical practice. Researchers should not rely solely on average values and summary statistics.

Clinical TrialTreatment of soft tissue defects with exposed bone in the head and face region with alginates and hydrocolloid dressings.
In cases of soft tissue defects with exposed bone surfaces in the head and face region, there is the option of treating the defect with free split-thickness skin grafts following appropriate wound granulation. Secondary granulation on free bone surfaces is often a lengthy process, as granulation primarily occurs from the edges of the wound. Hydrocolloid dressings are gaining increasing attention in this context. The question arises as to whether the positive properties of hydrocolloid dressings can bring about rapid and positive conditioning of the base of the wound in soft tissue defects with exposed bone in the head and face region, with a view to subsequent split-thickness skin graft transplantation. ⋯ On the whole, the combination of hydrocolloid dressing and alginate compress was found to have significant advantages as regards conditioning the exposed bone surface.
