Long-term results of external auditory canal closure and mastoid obliteration in cochlear implantation after radical mastoidectomy: a clinical and radiological study

Abstract Purpose The purpose of this retrospective study was to investigate the outcome and critical age of cochlear implantation in congenital single-sided deafness (SSD). Methods 11 children with congenital SSD were implanted with a cochlear implant (CI). Auditory performance was measured through the results of speech discrimination, subjective assessment by the Categories of auditory performance (CAP) score, the Speech, Spatial and Qualities scale questionnaire (SSQ) and the German version of the IOI-HA [Internationales Inventar zur Evaluation von Hörgeräten (IIEH, version for CI)]. Results Long-term follow-up [median: 3 years and 5 months (3;5 years)] revealed that nine children use their CI (> 8 h/day) and two became nonusers. In children aged below 3;2 years at surgery, there was a substantial long-term increase in speech discrimination and subjective benefit. Children over 4;4 years of age at CI surgery improved partially in audiological/subjective measurements. Among children above 5 years, the SSQ score did not improve despite further slight improvement in speech discrimination long-term. Conclusion Our data suggest a critical age for CI surgery below 3 years in children with congenital SSD for successful hearing rehabilitation. It is mandatory to identify children with SSD as early as bilaterally deaf children.

Acquired Atresia

Objectives: I describe the clinical symptoms and signs of acquired atresia of the external auditory canal (EAC) and the technique used to manage it. Methods: Forty-one consecutive patients affected by acquired atresia of the EAC were assessed by otoscopy, pure tone audiometry, computed tomography, and traditional and echo-planar diffusion-weighted magnetic resonance imaging. The anatomic and functional hearing results were evaluated. Results: At surgery for acquired atresia of the EAC, an EAC cholesteatoma was found in 3 of the 41 patients. Twenty-three of the 41 patients were followed for at least 5 years. Recurrence was seen in 9 of the 25 ears (36%) over the entire period of observation. Twenty-one, 23, and 22 of the patients had a normal or nearly normal contour and size of the ear canal at 6 months, 1 year, and 5 years, respectively. The results were similar for the air-bone gap. Conclusions: The main complication following surgery was recurrence. There was recurrence at 6 months in 4 patients (16%). Recurrence was seen in 12% of the cases at the 5-year follow-up. Similar findings were clear on evaluation of the hearing results. This result demonstrates that the surgical procedure, even when performed correctly, did not afford a stable, long-lasting outcome in a cohort of patients.

Objective: To report the long-term results of epitympanoplasty with mastoid obliteration technique. Subjects and Methods: Two hundred adult cases had undergone epitympanoplasty with mastoid obliteration from December 1994 to May 2003. The mean postoperative observation period was 91 months, with a minimum of five years. Epitympanoplasty with mastoid obliteration technique has four major procedures: the widening of the external auditory canal and removal of the scutum; preservation of the posterior canal wall; epitympanoplasty; and mastoid obliteration. We examined postoperative complications and hearing outcomes. Results: There was no retraction pocket formation and recurrence of cholesteatoma. Residual cholesteatoma in the tympanic cavity was seen in 10 cases (5%) and three cases were seen in the mastoid cavity (1.5%). Other complications were otorrhea (15 cases), perforation (8 cases), material extrusion (6 cases), and posterior auricular infection (4 cases). The average preoperative pure tone air-bone gap, postoperative pure tone air-bone gap, and air-bone gap closure were 31.5 ± 12.4 dB, 25.3 ± 12.2 dB, and 6.2 ± 12.6 dB, respectively. There were significant differences between the preoperative and postoperative values ( P < 0.01). Conclusions: The authors believe that epitympanoplasty with mastoid obliteration technique can combine the advantages of canal wall down and canal wall up techniques while improving their shortcomings.

Long Term Recurrence Rate

AbstractDuring the years 1979–81, three different surgical techniques were used in the treatment of 87 ears with extensive cholesteatoma. All procedures were performed in one stage by the same surgeon. Ten to 13 years after the operations about 70 per cent of ears operated on by the canal wall up technique had developed a new cholesteatoma, which in most cases was recurrent, or a deep retraction pocket. A modification of this technique with mastoid obliteration resulted in a similar failure rate. In contrast, ears operated on by the canal wall down technique (in most cases with mastoid obliteration) had acceptable stability with a long-term recurrence rate of about 15 per cent. Most patients in the canal wall down group had a dry ear without significant cavity problems. Hearing in these patients was as least as good as hearing in patients with a preserved canal wall. We conclude that a meticulous one-stage canal wall down technique in ears with extensive cholesteatoma results in a high percentage of unproblematic, stable ears with satisfactory function. In contrast, if the posteriorcanal wall is preserved, recurrent cholesteatoma is the rule more than the exception.
