To evaluate the long-term results after otoplasty on prominent ears. ⋯ With time, a substantial loss of correction can be expected in most (but not all) patients who undergo otoplasty, particularly at the upper pole. Overall, patients and their families are happy with the results of otoplasty surgery.

To establish whether histopathologic variables other than the pathologist's statement of complete excision predict recurrence of squamous cell carcinoma at the primary site and therefore indicate local postoperative radiotherapy. ⋯ When excision of a small squamous cell carcinoma of the mobile tongue or the floor of the mouth is histologically complete, other histopathologic variables are irrelevant in predicting recurrence at the primary site, and local radiotherapy is not indicated, considering the morbidity and high number of second and third primary tumors to be expected that will require future new treatment.

Comparative Study
Brain-derived neurotrophic factor and collagen tubulization enhance functional recovery after peripheral nerve transection and repair.
To investigate the effect of brain-derived neurotrophic factor (BDNF) and collagen tubulization (CT) on the regeneration of transected peripheral nerves. METHODS AND DESIGNS: The left sciatic nerve of 40 Sprague-Dawley rats was transected then repaired using one of four techniques; epineurial coaptation, CT, CT with BDNF delivered by an osmotic pump to the repair site, or CT with BDNF covalently cross-linked to the collagen matrix (CT/linked-BDNF). Sciatic functional indices were measured preoperatively at 10-day intervals for 90 days. Segments of the sciatic nerves proximal and distal to the repair site were harvested at 90 days for histologic and morphometric evaluation. ⋯ Brain-derived neurotrophic factor and CT improve the rate and the degree to which recovery of sciatic function occurs after nerve transection and repair. Animals repaired by CT/BDNF-linked demonstrated the most favorable functional recovery of all groups. Animals whose repair technique included BDNF had the largest mean axon diameters of all groups.

To describe the conversion of benign paroxysmal positional vertigo involving the posterior canal into benign paroxysmal positional vertigo involving the anterior or horizontal canals after treatment using the canalith repositioning maneuver. ⋯ Careful observation of the direction of the nystagmus is necessary for correct identification of which canal is involved in patients who do not respond to the initial treatment using the canalith repositioning maneuver.

Randomized Controlled Trial Clinical Trial
The effect of intravenous dexamethasone in pediatric adenotonsillectomy.
To determine whether the intravenous administration of dexamethasone sodium phosphate before tonsillectomy and adenoidectomy can reduce the morbidity from, and increase the safety of, this procedure. ⋯ Treatment with intravenous dexamethasone before electrocautery tonsillectomy and adenoidectomy is safe, increases early postoperative oral intake, and decreases morbidity.
