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 cholesteatoma surgery with canal wall down tympanoplasty and ossicular chain reconstruction.

Abstract Background This study was designed to evaluate the effect of mastoid cavity obliteration with bone chips and reconstruction of canal wall with tragal cartilage after canal wall down tympanomastoidectomy with cartilage ossiculoplasty in the same session. Sixty-three patients with cholesteatoma underwent the technique mentioned above; patients were followed for 1 year postoperative. Results No cavity problems, median preoperative air bone gap was 32.86 ± 6.24 db, while the median postoperative air bone gap was 21.67 ± 5.99 db. Conclusions Canal wall down mastoidectomy with obliteration of mastoid cavity is an effective option for the complete removal of cholesteatoma and same session cartilage ossiculoplasty is a viable option.

We prefer the intact canal wall technique for tympanoplasty with mastoidectomy, but use a canal wall down procedure in up to 25 % of oases. Creating a round cavity with a large meatus is imperative if one is to obtain a trouble-free ear. The five types of canal wall down procedures are defined, as are our indications for using them. Results in 19 only hearing ears and 19 labyrinthine fistula cases are presented, along with 64 tympanoplasty cases.

AbstractObjectiveThis study sought to compare disease recidivism rates between canal wall up mastoidectomy and a canal wall down with obliteration technique.MethodsPatients undergoing primary cholesteatoma surgery at our institution over a five-year period (2013–2017) using the aforementioned techniques were eligible for inclusion in the study. Rates of discharge and disease recidivism were analysed using chi-square statistics.ResultsA total of 104 ears (98 patients) were included. The mean follow-up period was 30 months (range, 12–52 months). A canal wall down with mastoid obliteration technique was performed in 55 cases and a canal wall up approach was performed in 49 cases. Disease recidivism rates were 7.3 per cent and 16.3 per cent in the canal wall down with mastoid obliteration and canal wall up groups respectively (p = 0.02), whilst discharge rates were similar (7.3 per cent and 10.2 per cent respectively).ConclusionOur direct comparative data suggest that canal wall down mastoidectomy with obliteration is superior to a canal wall up technique in primary cholesteatoma surgery, providing a lower recidivism rate combined with a low post-operative ear discharge rate.

Canal Dehiscence

Our aim was to investigate the relationship between facial canal dehiscence (FCD) and surgical findings and procedures in patients with cholesteatoma. A total of 186 patients (118 males, 39.2 ± 15 years) who underwent surgery for advanced cholesteatoma between 2013 and 2018 were included in the study. The relationship between FCD and surgical findings was investigated via the surgical registries. The prevalence of FCD was 36.6% (68/186). The prevalence of FCD was 44%, and 13.2% for the patients who underwent canal wall down mastoidectomy (62/141) and canal wall up mastoidectomy (6/45), respectively ( P < .001). Facial canal dehiscence was detected in 73.9% of the 23 patients who had a lateral semicircular canal (LSCC) defect ( P < .001), in 61.9% of 21 patients who had a tegmen tympani defect, and in 58.1% of the 31 patients who had erosion on the posterior wall of the external auditory canal (EAC; P < .05). The prevalence of FCD was 3.1% in patients with isolated incus erosion, 59.1% in patients with erosion of malleus and incus, 60.7% in patients with erosion of stapes suprastructure and incus, and 43.2% in patients with whole ossicular chain deformation ( P < .001). The defects on LSCC, EAC, tegmen tympani, and malleus and incus might be cautionary findings for the presence of FCD during cholesteatoma surgery.

Introduction Canal wall down (CWD) mastoidectomy has many drawbacks, including chronic otorrhea not responding to medications, granulations, dizziness on exposure to cold or hot water, and tendency of debris accumulation in the mastoid cavity, demanding periodic cleaning. Many of these problems can be solved by reconstruction of the posterior meatal wall (PMW). Objectives To assess the results of PMW reconstruction after CWD mastoidectomy for cholesteatoma using titanium mesh and platelet-rich plasma (PRP) mixed with bone pate. Methods This study was conducted with 20 patients that have atticoantral chronic suppurative otitis media. All cases were subjected to CWD mastoid surgery with complete elimination of the disease and reconstruction of the PMW by titanium mesh and the mixture of PRP with bone pate. All patients were exposed to a full preoperative evaluation and full postoperative assessment of the complications, the appearance of the external auditory canal contour, and the hearing gain expressed by the change of the air bone gap postoperatively. Results The PMW reconstructed by titanium mesh and the mixture of PRP with bone pate showed a smooth contour. During the follow-up of 12 to 36 months, the postoperative appearance of the external auditory canal contour was found to be smooth without hidden pouches, irregularities or stenosis in all cases. No granulation, foreign body reaction, or extrusion and/or displacement of the titanium mesh were registered. No facial palsy or recurrent cholesteatoma was reported. Conclusion The surgical reconstruction of the PMW using PRP, bone pate and titanium mesh after CWD mastoidectomy appears to be reliable without considerable complications, giving a smooth appearance to the PMW.
