To correlate patient response and recurrence rate after canalith repositioning to clinical presentation and cause of BPPV. ⋯ Canalith repositioning was effective in 99% of patients based on elimination of nystagmus. Partial responders probably experienced resolution naturally over time because of a difference in pathophysiology. Higher recurrence rates can be expected when the cause is thought to involve an ongoing process.

Randomized Controlled Trial Clinical Trial
Efficacy of ondansetron for prevention of postoperative nausea and vomiting after outpatient ear surgery under local anesthesia.
To assess the efficacy and safety of intravenous ondansetron (4 mg) for the prevention of nausea and vomiting after middle ear surgery under local anesthesia. ⋯ Single-dose ondansetron (4 mg) given intravenously preoperatively significantly reduces postoperative vomiting in patients after tympanoplasty under local anesthesia and causes no adverse effects.

To measure the middle ear (ME) volume displaced when the pars tensa (PT) retracts during conditions of atelectasis (AT). ⋯ Retraction of the PT may counteract an important potential negative ME pressure (up to several hundred millimeters of water) depending on the degree of retraction and the extent of mastoid pneumatization.

The objective of this study was to validate measures taken to reduce the number of cerebrospinal fluid (CSF) leaks after removal of vestibular schwannomas to 0. ⋯ To our knowledge, this is the first series of 200 consecutive vestibular schwannoma patients operated by means of the enlarged TLA without a single CSF leak. When the appropriate measures are taken, the number of CSF leaks after removing tumors through the enlarged TLA must and can be reduced to 0.

To report on three cases of severe facial skin burns resulting from intraoperative facial nerve monitoring in patients undergoing parotidectomies. ⋯ Successful retracing of technical defaults with biomedical engineers at the device manufacturer have led to the upgrade of the facial nerve monitor apparatus. The benefits of facial nerve monitoring largely outweigh the fortuitous occurrence of skin burns reported in this study. Therefore, this complication should not represent a drawback to the use of facial nerve monitoring.
