To determine the acute and subacute cochlear effects of sublethal total body irradiation. ⋯ Radiation can affect the cochlea in the acute phase at the mid to high frequencies; further prediction for long-term effects requires longer follow-ups.

The objective of this study was to assess the intracochlear position and the extent of trauma to cochlear structures using a new prototype electrode carrier (Flex EAS). Special emphasis was placed on the practicality for combined electric and acoustic stimulation of the auditory system. ⋯ The new electrode prototype provides very good mechanical properties for safe and atraumatic implantation. All criteria for the use in hearing-preservation cochlear implantation for electric and acoustic stimulation were fulfilled. Surgical measures to prevent basal trauma appear to be very important.

Randomized Controlled Trial Clinical Trial
The effect of beta-blocker premedication on the surgical field during endoscopic sinus surgery.
A number of previous studies have tried to assess the effects of hypotension on the surgical field during endoscopic sinus surgery. These studies have been limited by inadequate sample sizes, lack of a control group, and limited data collection. The aim of the present study was to determine whether the routine use of beta-blockers as a pre-medication could improve the operative field in endoscopic sinus surgery. ⋯ Although "optimum" conditions were present in the patients receiving beta-blocker, the authors thought that the grading system was not discriminating enough to demonstrate a significant difference between the groups. The crucial finding in the study was the correlation between heart rate and surgical grade in the entire group. During endoscopic sinus surgery surgery, anesthetic manipulations should be directed at maintaining a low heart rate.

Randomized Controlled Trial Clinical Trial
Vibration with the canalith repositioning maneuver: a prospective randomized study to determine efficacy.
The objective was to determine whether the inclusion of vibration and additional treatment cycles has an effect on short- and long-term success rates in the treatment of benign paroxysmal positional vertigo with the canalith repositioning maneuver. ⋯ Vibration provided no additional benefit in initial treatment success or in reducing long-term relapse rates when included in the canalith repositioning maneuver. Many patients with benign paroxysmal positional vertigo require more than one canalith repositioning cycle at the time of initial treatment to relieve symptoms, but this does not indicate a higher likelihood for recurrence. No variable predicted a higher rate of recurrence.

The management of cerebrospinal fluid (CSF) rhinorrhea has evolved in recent years. The purpose of this comprehensive retrospective study is to assess issues related to the management of skull base defects associated with CSF rhinorrhea involving the nose and paranasal sinuses. ⋯ Multiple approaches to the management of CSF rhinorrhea can be successful. An endoscopic repair results in resolution of CSF rhinorrhea in the majority of cases. Patients with spontaneous CSF rhinorrhea, elevated BMI, lateral sphenoid leaks, and extensive skull base defects are at increased risk for recurrence. Alternative management options may need to be considered in these cases.
