“…The similar results of hearing after stapedotomy were found for 0.4 and 0.6 mm prostheses with small but considerable advantages in increasing BC and overclosure parameter for 0.6 mm prosthesis. The difference in OAE test was not found in evaluating the auditory results of stapedotomy, and also, the hearing rate of these individuals had significant results before and after surgery in all tests [13]. In another study that was published by Mohammad Khorsandi et al in 2018, the medical records of 995 patients with otosclerosis undergoing stapedectomy or stapedotomy was retrospectively investigated.…”

Introduction: In order to treat the symptoms of otosclerosis, various surgical and medical treatments are suggested. Surgical treatments are the choice. This study aimed to determine the incidence of vertigo and its cause in Iran, and the present study focused on this issue. Methods: This was a prospective cohort study carried out on patients with otosclerosis undergoing stapedotomy referred to Rasoul Akram hospital, Tehran during 2017-18. The patients aged below 18 or those who had a history of vertigo were excluded. Diapasonic and audiometric tests were carried out. The follow-ups included the time of admission (the day after surgery) for the presence of vertigo using visual analogue scale and diapasonic tests, one week after surgery using visual analogue scale and diapasonic tests, and one month after surgery using visual analogue scale and audiometry. The data were imported to SPSS v.22 software and analyzed. Results: The surgical complications that occurred after stapedotomy for patients in this center were as follows: 12.1%of subjects had vertigo one day after surgery, 8.6% had vertigo one week later, and 1.7% had vertigo one month later, thus, the frequency of vertigo was reduced overtime. Meanwhile, 91.4% of the patients had a better sense of hearing and only 1.7% suffered from tympanic membrane perforation. In 8.6% of subjects, there was a disturbance in the taste. Tinnitus was only observed in 5.2% of the surgical patients in this center. Among women, vertigo was higher one day and one week after surgery. Logistic regression showed that age is significant predictor of dizziness one day after surgery (OR: 1.37, P=0.03). Conclusion: According to the results, the frequency of vertigo was decreased overtime. In this study, it was found that the complications of stapedotomy surgery were less than other surgical methods, but those who were older had significantly higher vertigo a week and one day after surgery indicating effective role of age on postoperative complications. Those who underwent surgery by tympanomeatal method had a better vertigo one day and one week after surgery.

“…Some studies had similar findings as our study (suggesting there is no significant difference in outcome with use of different diameter of prosthesis), Gupta et al, Gristwood et al, Cavaliere et al, Faranesh et al, Wegner et al and other studies had findings contrary to our study. 6,8,[12][13][14] They preferred use of larger diameter of piston over smaller, The better result with larger diameter was assumed on basis of mathematical models on mechanical and acoustic analysis middle ear reconstruction (and on the biomechanics of stapedotomy), which seemed to indicate that a larger diameter piston is associated with better sound transmission to the inner ear. 21,22 Experimental study on temporal bone model by Sim et al, demonstrated that a larger diameter prosthesis increased the round window velocities, had better volume displacement at round window and better sound transmission slightly improving hearing results.…”

Background: Otosclerosis presents as conductive hearing loss, stapedotomy is the treatment for otosclerosis, and different sizes of piston diameter are available for the procedure. Aims and objectives were to study and compare hearing improvement between the 0.4 and 0.6 mm sizes of teflon piston in stapedotomy.Methods: It was a prospective randomized controlled trial. Patients fulfilling inclusion criteria were subjected for small fenestra stapedotomy. Patients were divided into two groups after randomization into group A (with 0.4 mm piston diameter) and group B (with 0.6 mm piston diameter). The hearing outcome with standard audiological assessment was performed at one month and six months postoperatively. Results: Comparison of 1 month AB gap among the patients with 0.4 mm piston and 0.6 mm piston showed that there was no statistically significant difference among both the groups of patients (independent t test p value=0.699). Comparison of 6 month AB gap among the patients with 0.4 mm piston and 0.6 mm piston showed that there was no statistically significant difference among both the groups of patients (independent t test p value=0.54).Conclusions: There was no significant difference in hearing improvement among the individual methods (piston size 0.4 and 0.6) with each other both in 1 month post-operative and 6 month post-operative follow up. Hence, we conclude that there is no relevance of different diameter of teflon piston prosthesis (0.4 mm versus 0.6 mm) as far as hearing outcome is concerned.

“…It has been shown that prostheses in lesser diameter increase MVA and decrease SSC (4). In addition to this, some clinical studies have shown better audiological results after stapedotomy with larger prosthesis (5)(6)(7)(8)(9), whereas the results of some other studies in the literature have not supported them (10)(11)(12)(13). The controversy has been ongoing in the literature.…”

To compare the outcomes of the stapedotomies performed using Teflon prostheses with 0.4 mm and 0.6 mm diameters. Materials and Methods: Pre-and postoperative audiograms of 52 participants, who had undergone stapedotomy, were evaluated retrospectively. Participants were divided into two groups according to the diameter of the prosthesis used for their surgery: Group 1 (0.4 mm) and Group 2 (0.6 mm). Air conduction (AC) pure tone thresholds at 250, 500, 1000, 2000, 4000, and 6000 Hz and air-bone gaps (ABGs) at 500, 1000, 2000, and 4000 Hz, as well as pure tone averages (PTAs), were compared within and between groups. Results: Hearing gain, with regard to AC thresholds and ABGs, was statistically significant within both groups for each frequency (p<0.05). Pre-and postoperative PTAs and ABGs were similar between the groups (p>0.05). Whereas the preoperative AC thresholds were similar between the groups at all frequencies, postoperative AC thresholds of the 0.6 mm group were better than those of the 0.4 mm group at 2000 Hz (p<0.05). However, postoperative AC thresholds were similar between the groups at all frequencies other than 2000 Hz (p>0.05). Conclusion: The outcomes of the stapedotomies with 0.4 and 0.6 mm Teflon prostheses were similar to each other with regard to postoperative hearing gain, PTA, and ABG. However, only at 2000 Hz, AC thresholds were found to be better in patients with a 0.6 mm prosthesis than in those with a 0.4 mm prosthesis.
