We studied 29 patients (32 cases) who had been identified temporal bone fractures with the temporal bone C-T scan after external head injury from June, 1986 to July, 1989.
All the patients underwent a through physical, radiologic and audiometric examinations.
The results were as follows;
1. Of the 29 patients, 24 patients were men and 5 patients were women (3 patients of men were bilateral temporal bone fracture).
2. Of temporal bone fractures,
1) Longitudinal fractures were 20 cases (62.5%),
2) Transverse fractures were 4 cases (12.5%),
3) Mixed fractures were 8 cases (25.0%).
3. They were injured in automobile accident (15 patients, 51.8%), bomb accident (7 patients 24.1%), falling down accident (5 patients, 17.2%) and head blow (2 patients, 6.9%).
4. Comparison of CT with mastoid X-ray, fracture line of the temporal bone was identified in the mastoid X-ray of 19 cases (59.4%).
5. On otologic symptoms and signs,
1) Ear bleeding was 25 cases (78.1%),
2) Hearng impairment was 23 cases (71.9%),
3) Tinnitus was 19 cases (59.4%),
4) Facial palsy was 16 cases (50.0%),
5) Vertigo was 5 cases (15.6%).
6. On hearing loss of temporal bone fractures,
1) Conductive hearing loss was 15 cases (65.3%),
2) Sensorineural hearing loss was 3 cases (13.0%),
3) Mixed hearing loss was 5 cases (21.7%).
7. Of the cases of operative treatment,
1) Facial nerve decompression was performed on 6 cases,
2) Ossiculoplasty was performed on 3 cases,
3) Canaloplasty was perfermed en 1 cases.
8. Follow-up,
1) Follow-up of 17 cases of hearing loss, 12 cases were improved, 4 cases were not improved, and 1 cases was further exacerbated.
2) Follow-up of 12 cases of facial nerve palsy, 6 cases were improved and 6 cases were not improved.
