Hearing improvement after stapedotomy using teflon loop prosthesis.
OBJECTIVE
To assess hearing improvement after stapedotomy for otosclerosis using teflon loop prosthesis.


METHODS
Quasy experimental study.


METHODS
January 2001 to May 2003 in the Otorhinolaryngology Department, CMH, Rawalpindi.


METHODS
Thirty diagnosed cases of otosclerosis were included in the study. Ear with greater air-bone gap was selected and stapedotomy was done using teflon loop prosthesis (size 4 - 4.5 mm). Mild vertigo occurred during immediate postoperative period, which subsided with Inj. Prochlorperazine. Patients were followed-up postsurgically at one month, two months, four months, six months and one year and postoperative air-bone gap was calculated.


RESULTS
Out of 30 cases, there were 24 males and 06 females. The age ranged from 18 to 50 years. Twenty-one (70%) patients had bilateral hearing loss and 09 (30%) had tinnitis also. Pre-operative audiograms showed conductive deafness. Carhart's notch was present in 10 (33.3%) cases. Tympanogram revealed loss of stapedial reflex. Postoperatively good hearing improvement was seen in 56.7% (postoperative air-bone gap closure upto 10 dB), fair improvement in 30% (postoperative air bone gap closure from 11 to 20 dB) and poor results in 10% (postoperative air-bone gap more than 21 dB) cases. One patient developed dead ear.


CONCLUSIONS
Stapedotomy using teflon loop prosthesis for otosclerosis is an effective method to restore hearing. Complications are uncommon.
