To investigate the effects of surgery type [intact canal wall (ICW) or canal wall down (CWD) mastoidectomy] and different ossiculoplasty materials on hearing outcome in single-staged cholesteatoma surgery. A retrospective case-control study. A total of 116 cases (97 adults, 29 children) underwent surgery, including ossiculoplasty, between 2012 and 2015 for cholesteatoma. Patients who had undergone surgery for the first time, and whose grafts were successful, were included in the study. Patients with adhesive otitis media, unsuccessful grafts, revision and recurrent cases, radical mastoidectomy, and craniofacial anomalies were excluded. Audiogram examinations of the enrolled patients were performed 3-6 months after surgery, and the audiometric results were analyzed according to the criteria of the American Academy of Otolaryngology, Head and Neck Surgery. All ossiculoplasties were performed during the first operation. The preoperative average air-bone gap (ABG) of the patients was decreased from 31.37 ± 10.1 to 27.42 ± 10.4 dB; this decrease was found to be highly significant (p = 0.0001). Concerning the ICW technique, statistical evaluation of the hearing gain at frequencies of 500, 1000, and 2000 Hz, as well as the mean frequency, showed a high level of significance. Improvement at 4000 Hz was not found to be statistically significant. When the ABGs at 500, 1000, 2000, and 4000 Hz, and the mean frequency in patients with an hydroxyapatitepartial ossicular replacement prosthesis (HA-PORP) or autograft-partial ossicular replacement prosthesis (APORP), were evaluated, it was found that, at 4000 Hz, the APORP significantly reduced the ABG (p = 0.02). No significant difference was determined between patients with the hydroxyapatite-total ossicular replacement prosthesis (HA-TORP) and those with the autograft-total ossicular replacement prosthesis (ATORP) (p = 0.565). Although the use of the malleus as an APORP was found to be less effective than other autografts, the degree of advantage of using the incus, malleus, cortical bone, and cartilage did not significantly differ between materials (p = 0.152). Despite the effects of the incus, malleus, and cortical bone not differing in terms of the postoperative ABG (p = 0.160), incus usage was highly beneficial for hearing gain (p = 0.009). Despite CWD tympanoplasty affecting all frequencies, it has a particularly negative effect on the hearing threshold at 1000 Hz. In patients with partial ossicular replacement, autogenous grafts are more successful in restoring hearing at high frequencies, particularly at 4000 Hz. Although autogenous materials do not differ in terms of partial replacement effectiveness, the incus has been shown to be most effective for total replacement.
A Study of Ossiculoplasty in Chronic Otitis Media using different types of Prostheses
Bengal Journal of Otolaryngology and Head Neck Surgery, 2013
Introduction: A wide range of prostheses, autologus and synthetic are available for use these days. Ideally, the ossicular reconstruction prosthesis should be biocompatible, safe, easy to handle and capable of efficient sound transmission. Aim and objectives: To study operative ease and post-operative hearing results in patients undergoing ossiculoplasty with different types of prostheses. Materials and methods: A prospective randomized study of 25 patients with Chronic Otitis Media, undergoing ossiculoplasty was conducted at Command Hospital, Kolkata. Tragal cartilage was used in 05 patients, conchal cartilage in 05, refashioned incus in 05, hydroxyapatite in 05 and titanium prostheses in 05 patients. Subjects with mixed hearing loss, multiple co-morbidities and revision surgeries were excluded. Hearing assessment was done by pure tone audiometry pre-operatively and 04 and 12 weeks postoperatively. Results were analyzed statistically. Results: Using tragal or conchal cartilage took...

Conclusions: Titanium proved to be a valuable alternative to ossicles in ossiculoplasty procedures. Complication rates are comparable to those obtained by other authors with titanium and nontitanium prostheses. Hearing results were worse compared with other reports; however, no conclusion can be drawn on the basis of the literature because of the heterogeneity of the populations studied. Objectives: To evaluate the results and complications of total (TORP) and partial (PORP) titanium ossicular replacement prostheses in middle ear cholesteatoma. Methods: Fifty-seven patients affected by acquired cholesteatoma of the middle ear undergoing titanium ossiculoplasty during second stage intact canal wall tympanoplasty were evaluated. Postoperative hearing gain, complication rate, and revision rate were analyzed. Results: Average postoperative gain was 13.6 dB HL for PORP and 17.9 dB HL for TORP. After ossicular reconstruction the mean postoperative ABG was 24.1 dB HL in PORPs and 27.2 dB HL in TORPs. The difference in air-bone gap (ABG) between the two groups after ossiculoplasty was not significant. The number of patients with an ABG > 30 dB was higher in the TORP group compared with the PORP group (p = 0.024) after ossicular reconstruction. The total extrusion rate was 5.2% and the total revision rate was 10.5%.
Ossiculoplasty in chronic otitis media: Surgical results and prognostic factors of surgical success
Acta Otorrinolaringológica Española, 2017
Background and objectives: The goal of ossiculoplasty is to improve hearing. Successful ossiculoplasty depends on several factors. This retrospective study was carried out to analyze hearing results of ossiculoplasty in ears with chronic otitis media (COM) and evaluate clinical outcomes and factors predictive of hearing improvement. Subjects and methods: We reviewed the results of 153 patients with COM (with cholesteatoma (COMC) and without cholesteatoma (COMWC)) who underwent ossiculoplasty between January of 2002 to December of 2011. Several potential prognostic factors were evaluated: cholesteatoma present vs absent; type of surgical procedure, state of the middle ear mucosa, state of the ossicular chain, type of prosthesis. Results: We analyzed 153 ossiculoplasties: 96 patients presented COMWC and 57 patients presented COMC. The ossiculoplasties were performed using autologous ossicles for the most part. All ossiculoplasties were carried out in one-stage surgery. In 38% of cases ossiculoplasty was combined with mastoidectomy; in the remaining 62% of cases, ossiculoplasty was performed without mastoidectomy. Ossiculoplasty was successfully achieved in 113 patients (74%). The presence of the stapes superstructure and normal mucosa were significant predictive factors of surgical success. Conclusion: The majority of the ossiculoplasties improved hearing status satisfactorily. Multivariate analysis should be performed to investigate prognostic factors of favorable short-term hearing outcomes after ossiculoplasty. Better knowledge of these predictive factors may contribute to the surgeon's judgment and the information given to patients.
Audiological Results of Total Ossicular Replacement Prosthesis with Cartilage Shoe Technique
Turkish archives of otorhinolaryngology, 2018
The aim of this study was to investigate functional results of total ossicular replacement prosthesis (TORP) shaft stabilization with a cartilage shoe in chronic otitis media patients with cholesteatoma who had undergone canal wall down tympanomastoidectomy (CWDT). In addition, it was determined whether the presence of granular and edematous mucosa in middle ear altered functional outcomes. Sixty patients, who had undergone CWDT with the use of TORP for the reconstruction of ossicular chain, were divided into two groups. Patients with cartilage shoe were classified as Group 1 (n=30) and those without the shoe were classified as Group 2 (n=30). Patients in both groups were classified into "A" and "B" subgroups according to the middle ear risk index (MERI). Air conduction (AC) and bone conduction thresholds were evaluated preoperatively and postoperatively. There was no statistically significant change between preoperative AC thresholds of the groups and subgroups ...

Introduction: Posterior tympanotomy (PT) is often performed during the surgical management of middle ear cholesteatoma with extension in the retrotympanum area. This PT can also be used to control the right position of the ossicular prosthesis masked by the tympanic membrane reconstruction. Objective: To compare audiologic results after ossiculoplasty performed via the outer ear canal and via the PT for patients with cholesteatoma. Materials and Methods: Retrospective chart reviews were performed for 68 patients (68 ears) with cholesteatoma who underwent titanium ossicular prosthesis surgery between January 2007 and January 2011. We compared audiologic results between two groups: the WPT group (the group without checking the prosthesis via the PT) and the PT group (the group with placing and/or checking the prosthesis via the PT). A postoperative pure-tone average air-bone gap of 20 dB or less was considered a successful hearing result. Results: Of the patients who underwent canal wall-up mastoidectomy for cholesteatoma with ossicular chain reconstruction by titanium prosthesis, 36 patients (20 total ossicular replacement prosthesis [TORP], 16 partial ossicular replacement prosthesis [PORP]) were in the PT group and 32 patients (16 TORP, 16 PORP) were in the WPT group. The global success rate (defined as a mean residual air-bone gap < 20 dB) was 50% in the WPT group (56% in the subgroup PORP, 44% in the subgroup TORP) and 42% in the PT group (62% in PORP, 25% in TORP). There was no case with extrusion of the prosthesis in either group. No facial palsy occurred during the postoperative period for either group. Conclusion: Control of ossicular prosthesis positioning via the PT does not improve hearing results after ossicular chain reconstruction in cholesteatoma surgery. However, this approach can be used during a second-stage procedure that avoids incisions within the external ear canal.

Background: The main purpose of surgery in cases of chronic otitis media is to eradicate the infection and restore the middle ear hearing function. Both intact tympanic membrane and ossicular chain are essential for the restoration of hearing in these cases. The world of material science has provided otologists with array of biomaterials for middle ear reconstruction. The use of ossicular graft material in ossicular chain reconstruction has significantly improved hearing results after surgeries for chronic otitis media.Methods: The study involved a total of 50 patients presenting with dry tympanic membrane perforation with ossicular disruption and air-bone gap (ABG) of >25 from July 2014 to December 2019. The patients were randomly allotted into two groups and they underwent tympanomastoidectomy with ossiculoplasty, in one group homologous incus was used as ossiculoplasty material and in the second group Teflon TORP/PORP was used as ossiculoplasty material.Results: The present st...
Primary ossiculoplasties provide better hearing results than revisions: a retrospective cohort study
European Archives of Oto-Rhino-Laryngology
Purpose To evaluate the efficacy of ossicular chain reconstruction (OCR) in primary and revision surgeries, and to investigate the impact of the number of previous surgeries on hearing outcomes. Methods Retrospective analysis of cases with OCR due to chronic otitis in a tertiary center between January 2018 and September 2021. Results Altogether, 147 cases of ossicle involvement were assessed. In 91.83% (n = 135) OCR was performed, 96.26% of them with titanium TORP/PORP (n = 130), two cases with autologous prosthesis and three with piston. Mean follow-up was 8.8 months. The ABG significantly improved in the total group (TORP/PORP) from a mean (SD) of 30.94 (15.55) to 19.76 (13.36) dB (p < 0.0001) with 60.86% success. The best results were achieved in primary OCR with PORP implantation without cholesteatoma (89.47%). Primary cases have a significantly higher success rate in contrary to revision surgeries (72.27%, vs. 52.00%, p = 0.032). The only relevant predictive factor proved to...

The aim of this study was to evaluate the hearing results of ossiculoplasty in canal wall down tympanoplasty in one stage middle-ear cholesteatoma surgery.We carried out a retrospective review of a consecutive series of 142 cases which had undergone type two or three canal wall down tympanoplasty with ossicular reconstruction, between January 1995 and December 2002, due to chronic otitis media with cholesteatoma.Pre-operative audiometric testing revealed a mean air conduction pure tone average (PTA) of 50.97 dB and a mean bone conduction PTA of 22.14 dB. The mean post-operative result for air conduction PTA was 37.62 and for bone conduction PTA was 23.37 dB. The mean pre- and post-operative air–bone gaps (ABGs) were 28.83 and 13.94 dB, respectively, with a gain of 14.89 dB. Almost 62.67 per cent of patients closed their ABGs to within 20 dB.Our functional results are comparable with those of other authors. In the present study, we show that hearing improvement is possible following ...
