Audiometric evaluation after stapedotomy with Fisch titanium prosthesis

“…The literature indicates that incidence rates are significantly higher in female subjects 21 , 22 , 23 , 24 . Reported ratios range from 2:1 to 3:1 in some series 1 , 21 , 22 , 23 .…”

“…The literature indicates that incidence rates are significantly higher in female subjects 21 , 22 , 23 , 24 . Reported ratios range from 2:1 to 3:1 in some series 1 , 21 , 22 , 23 . Hormonal differences have been mentioned as a possible explanation for the higher prevalence in females, and reports of worsening condition after pregnancy have been described in the literature.…”

“…Hormonal differences have been mentioned as a possible explanation for the higher prevalence in females, and reports of worsening condition after pregnancy have been described in the literature. But this issue is yet to be fully comprehended 22 , 23 . In our study, 21 of the 33 patients were females, thus keeping with the 2:1 ratio previously described for individuals with otosclerosis.…”

“…The time after surgery one should wait before testing the patient's hearing is a very important factor in the assessment of auditory outcomes 6 , 21 , as good results seen early on within months of surgery may deteriorate during long term follow-up 9 , 23 . In light of this fact, the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology recommended that audiological tests should be carried out at least a year after surgery 14 .…”

“…However, in these three alternatives the surgeon has no control over how tight the prosthesis is in the incus, which may leave it either too tight or too loose and lead to problems related to inadequate device stability, thus increasing the risk of poor fitting in incus bones of extreme sizes and lateral migration of the prosthesis 4 , 21 , 23 . Therefore, the literature shows that despite the self-fitting alternatives, manual crimping is still a safe, effective procedure.…”
