Canal Wall Down Mastoidectomy

We report a rare case of a temporal bone encephalocele after a canal wall down mastoidectomy performed to treat chronic otitis media with cholesteatoma. The patient was treated successfully via an intracranial approach. An enhanced layer-by-layer repair of the encephalocele and skull base deficit was achieved from intradurally to extradurally, using temporalis fascia, nasal septum cartilage, and artificial dural graft. After a 22-month follow-up period the patient remains symptom free and no recurrence is noted.

In a 144-month period, 27 cases of labyrinthine fistula (LF) were seen, and 360 mastoid operations were performed; the LF prevalence was 7.5%. Primary symptoms were hypoacusis, otorrhea, vertigo, tinnitus, and otalgia. All patients underwent preoperative CT scans and preoperative audiometry. LF diagnosis was made before surgery for 93% of patients on the basis of symptoms, signs, and imaging studies. With respect to surgical technique, the canal-wall-down procedure was performed in 92%, and the canal-wall-up procedure was performed in 8%. In 88% of patients the fistula was located in the horizontal semicircular canal. In 96% of patients the cholesteatoma matrix was removed, and the fistula was sealed; in 4% of patients the matrix was left. With a follow-up of 13 years, vertigo disappeared in 96% of patients, and hearing remained unchanged in 70% of patients. Further complications of chronic otitis media existed in approximately half of the patients with LF. Open surgery with removal of the cholesteatoma matrix and sealing of the fistula with temporalis fascia in a canal-wall-down manner is a safe procedure that can make vertigo disappear and helps to preserve cochlear function.

Objectives: To analyze hearing outcomes following Type 3 tympanoplasty with stapes columella grafting after canal wall down mastoidectomy and determine disease recurrence rates in patients undergoing this procedure. Methods: This retrospective cohort analysis examines patients undergoing Type 3 tympanoplasty with stapes columella grafting following canal wall down mastoidectomy for cholesteatoma at a tertiary care center from 2005 to 2015. Patient charts were reviewed for demographic data, diagnosis, and operative details. Patients were included in statistical analysis if they were found to have undergone the aforementioned procedure. Evaluation of hearing improvement was made by comparing preoperative air-bone gap (ABG) and ABG at follow-up at 6 months and 1 year postoperatively. Results: Nineteen patients met criteria for this study. Erosion of the otic capsule, posterior fossa plate, or tegmen was noted in 37% of cases, highlighting disease severity. Eighteen (95%) had undergone prior otologic surgery. Mean time to short-term follow-up was 6 ± 3 months. The average short-term ABG was 26 ± 11 dB HL; 26% achieved an ABG <20 dB, and 58% achieved an ABG <30 dB. Fifteen had follow-up at least 1 year postoperatively (mean = 33 ± 16 months). At longer-term follow-up, mean ABG was 25 ± 10 dB HL; 33% achieved an ABG <20 dB, while 66% achieved an ABG <30 dB. Hearing remained stable over time ( P = .52). At date of last clinical follow-up, only 1 (5%) patient had undergone revision for recurrent disease. Conclusion: In some patients undergoing canal wall down mastoidectomy for advanced or recurrent cholesteatoma, Type 3 tympanoplasty with stapes columella grafting yields marginal hearing benefit. This type of reconstruction is a viable option in this challenging patient cohort, particularly as it is associated with low rates of revision surgery.

Background and Objectives The aim of this study was to investigate the surgical outcomes of revision operation due to recurrence of non-cholesteatomatous chronic otitis media (COM) surgery cases.Subjects and Method From 1989 to 2018, 5197 cases of COM surgery were performed at Kangdong and Hallym University Sacred Heart Hospital. Among them, clinical data of 297 subjects who had undergone revision tympanoplasty and/or mastoidectomy for recurrent noncholesteatomatous COM were retrospectively collected from computerized database of middle ear surgery (Korean Otological Society program 2005). Each case was categorized by surgical approaches into canal wall down mastoidectomy (CWDM), canal wall up mastoidectomy (CWUM), or tympanoplasty only groups.Results Tympanoplasty only was performed in 170 cases, CWDM in 74 cases, and CMUM in 53 cases. Postoperative perforation occurred in 9.4% of total cases, and less frequently in CMDM compared with tympanoplasty only (<i>p</i>=0.023), and CMUM (<i>p</i>=0.049), respectively, whereas no differences between tympanoplasty only and CMUM (<i>p</i>=0.930) were found. Postoperative infection rate was 1.0% and did not show any differences among the groups. Postoperative successful hearing was obtained in 66.7% of total cases, and the success rate of tympanoplasty only was better than that of CMDM (<i>p</i>=0.001), and CMUM (<i>p</i>=0.011). And, that of CMUM was better than that of CMDM (<i>p</i>=0.011).Conclusion The results showed that postoperative perforation occurred less frequently in CMDM than in tympanoplasty only and in CWUM; successful hearing was achieved more frequently in tympanoplasty alone than in the other surgical approaches in recurrent non-cholesteatomatous COM.

Objectives: To see the hearing outcomes following Type III tympanoplasty with stapes columella grafting after canal wall down mastoidectomy and find out the recurrence rates in patients undergoing this procedure. Methods: This prospective observational study includes 120 cases undergoing Type III tympanoplasty with stapes columella grafting following canal wall down mastoidectomy for cholesteatoma at a tertiary care center from 2018 to 2020. Patient charts were reviewed for demographic data, diagnosis, and operative details. Patients were included in statistical analysis if they were found to have undergone the aforementioned procedure. Evaluation of hearing improvement was made by comparing preoperative air-bone gap (ABG) and ABG at follow-up at 6 months and 1 year postoperatively. Results: One hundred and twenty patients were included for this study. Erosion of the otic capsule, posterior fossa plate, or tegmen was noted in 20% of cases, highlighting disease severity. One hundred and two (85%) had undergone prior otologic surgery. Mean time to short-term follow-up was 6 ± 3 months. The average short-term ABG was 25 ± 12 dB HL; 36% achieved an ABG <20 dB and thirteen had follow-up at least 1 year postoperatively (mean = 33 ± 16 months). At longer-term follow-up, mean ABG was 24 ± 11 dB HL. Hearing remained stable over time (P = .26). Conclusion: In some patients undergoing canal wall down mastoidectomy for advanced or recurrent cholesteatoma, Type III tympanoplasty with stapes columella grafting yields marginal hearing benefit.

AbstractObjectiveSafe cochlear implantation is challenging in patients with canal wall down mastoid cavities, and the presence of large meatoplasties increases the risk of external canal overclosure. This paper describes our results of obliteration of the mastoid cavity with conchal cartilage as an alternative procedure in cases of canal wall down mastoidectomy with very large meatoplasty.MethodsThe cases of seven patients with a canal wall down mastoidectomy cavity who underwent cochlear implantation were retrospectively reviewed. Post-operative complications were analysed. The mean follow-up duration was 4.5 years.ResultsThere was no hint of cholesteatoma recurrence and all patients have been free of symptoms during follow up. Only one patient showed cable extrusion six months after surgery, and implantation of the contralateral ear was needed.ConclusionPseudo-obliteration of the mastoid cavity with a cartilage multi-layered palisade reconstruction covering the electrode may be a safe alternative in selected patients with a large meatoplasty.

Canal Wall Down

The aim of this study was to determine the effect of surgical approach, intact canal wall (ICW) or canal wall down (CWD), upon the success of revision surgery for chronicotitis media (COM). A retrospective analysis of 367 patients (including 65 children aged <15years) who underwent revision tympanoplasty because of persistent disease was performed. Single-staged tympanoplasty was performed, preserving the canal wall when present. Hearing was reconstructed with allograft incus. Follow-up ranged from one to 15 years. Hearing was determined by pre- and post-operative air-bone gaps.Post-operative re-perforation, aural discharge and/or cholesteatoma rates were similar for CWD and ICW. Cholesteatoma could present following the revision, even though it was not apparentat surgery. Following tympanoplasty, the final hearing was not significantly affected by the surgical approach or presence of cholesteatoma. Improvement in hearing was adversely affected by cholesteatoma or an absent stapes suprastructure.Revision ICW and CWD operations were both successful in controlling signs of COM. Cholesteatoma is a peripheral risk in COM and may become apparent after revision surgery.
