Oral prednisolone may be beneficial during recovery from tonsillectomy without causing any serious complications.

Background and ObjectivesInner ear symptoms like hearing loss, dizziness or tinnitus are often developed after head trauma, even in cases without inner ear destruction. This is also known as labyrinthine concussion. The purpose of this study is to determine the clinical manifestations, characteristics of audiometry and prognostic factors of these patients.Materials and MethodsWe reviewed the medical records of the 40 patients that had been diagnosed as labyrinthine concussion from 1996 to 2007. We studied the hearing levels in each frequency and classified them according to type and degree of hearing loss. Rates of hearing improvement were evaluated according to age, sex, hearing loss type, degree and presence of dizziness or tinnitus. To find out any correlation between hearing improvement and these factors, we used χ2 test or Fisher's exact test.ResultsBilateral hearing loss was observed in 22 patients, and unilateral hearing loss in 18 patients. There were 4 (6.5%) ascending, 34 (54.8%) descending, 24 (38.7%) flat type hearing loss, which indicated hearing loss was greater in high frequencies than low frequencies. Among 62 affected ears, 20 (32.3%) gained improvement, and it was achieved mainly in low frequencies. There were only 2 ears with dizziness in 20 improved ears and among 20 dizziness accompanied ears, also only 2 ears were improved.ConclusionsHigh frequencies are more vulnerable to trauma than low frequencies. The hearing gain is obtained mainly in low frequencies, and association with dizziness serves poor prognosis.

The epiphora was improved in 84.2% of the silicone stent group and 81.8% of the non-silicone stent group. Categorized by the level of obstruction, in common canalicular obstruction, the success rate was 84.5% (11/13) in the silicone stent group and 57.1% (4/7) in the no stent group. In NLD obstruction, the success rate was 83.0% (5/6) in the silicone stent group and 93.3% (14/15) in the no stent group.
