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.

The aim of this retrospective study was to evaluate the long-term hearing results of using costal cartilage prostheses in ossicular chain reconstruction procedures in subjects operated on for a middle ear cholesteatoma with an intact canal wall tympanoplasty. Thirty-six patients (four with bilateral disease) followed up for 10 years who underwent an ossiculoplasty with a cartilage prostheses between January 1987 and December 1989 constituted the population studied. All the subjects underwent a staged intact canal wall tympanoplasty with mastoidectomy. Ossiculoplasty with total or partial chondroprosthesis was performed during the second stage. The long-term outcome was evaluated in terms of hearing according to the guidelines of the Committee on Hearing and Equilibrium (1995), and in terms of complications (anatomical and functional). In 18 patients a partial cartilage ossicular replacement prosthesis (PORP) was used, while in 22 a total cartilage ossicular replacement prosthesis (TORP) was used. In the PORP group the mean preoperative air–bone gap (ABG) was 22.4 dB hearing level (HL); before the second stage the ABG was 37.9 dB HL, at 2 years it was 12.1 dB HL, at 5 years 15.3 dB HL and at 10 years 15.8 dB HL. In the TORP group the mean preoperative ABG was 31.6 dB HL; before the second stage the ABG was 41.1 dB HL, at 2 years it was 14.4 dB HL, at 5 years 17 dB HL and at 10 years 18.5 dB HL. In both groups the number of cases with a postoperative ABG of < 20 dB HL remained stable (P > 0.05) over time. The failure rate was 17.5%, but only in 5% of cases was a functional revision needed. No cases of extrusion of the prostheses were encountered. The use of a chondroprosthesis is associated with functional results similar to those obtained by other authors. The efficacy of the prostheses remains stable over time and is associated with a very low rate of complications and failures. In this series no extrusion occurred and in no case did an infectious disease develop after cartilage transplantation.

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%.

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.

OBJECTIVE: The aim of this study was to evaluate which factors are best predictors of hearing improvement after tympanoplasty and to evaluate best functional outcome in different forms of pathology in the tympanic cavity and mastoid in chronic otitis media. METHODS: Prospective study included 120 patients who were operated for chronic suppurative otitis media and cholesteatoma in the ENT Department University Clinic Center Banja Luka from 2006 to 2011. Multiple linear regression analysis was used to measure which factors predict better hearing improvement. MAIN OUTCOME MEASURES: A model that evaluates factors related to chronic otitis media: ossicular chain integrity, tympanic tube function, tympanic membrane perforation, type of surgery and condition of tympanic and mastoid walls was used to predict postoperative hearing improvement. Hearing outcome was measured comparing preoperative to postoperative pure-tone average (PTA) and postoperative air-bone gap (ABG). RESULTS: Out of 120...

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 ...

To compare the results obtained with canal wall up (CWU) tympanoplasty for cholesteatoma using cartilage or an hydroxyapatite (HA) PORP positioned on the head of the stapes and to analyse the impact of malleus removal and total reinforcement of the tympanic membrane with cartilage. Retrospective study of 128 cases (99 adults, 29 children) operated between 2003 and 2012 for cholesteatoma by CWU tympanoplasty with use of a cartilage graft (90 cases) or a PORP (38 cases) on the head of the stapes. Audiometric results were analysed according to the International Bureau for Audiophonology (BIAP) criteria and were submitted to statistical analysis. All ossiculoplasties were performed during the first operation and only 39% of patients required surgical revision. The malleus was preserved in 79 cases and sacrificed in 49 cases. With a follow-up of 2 years, the residual mean air-bone gap was 16.8 dB in the cartilage group (gain of 7.6 dB; P = 0.001) and 15.8 dB in the PORP group (gain of 8....
