Round Window Niche

Objective: To investigate the anatomical status of the round window niche and hearing outcome of cochlear implantation (CI) after explorative tympanotomy (ExT) with sealing of the round window membrane in patients with sudden sensorineural hearing loss at a tertiary referral medical center. Methods: Between January 1, 2007, and July 30, 2020, 1602 patients underwent CI at our department. Out of these, all patients previously treated by ExT with sealing of the round window membrane because of unilateral sudden hearing loss were included in the study. A retrospective chart review was conducted concerning method of round window membrane sealing, intraoperative findings during CI, postoperative imaging, and hearing results. Results: Twenty one patients (9 females; 8 right ears; 54.3 years [± 12.9 years]) underwent ExT with sealing of the round window membrane with subsequent CI after 26.6 months (± 32.9 mo) on average. During CI, in 76% of cases (n = 16), the round window niche was blocked by connective tissue due to the previous intervention but could be removed completely in all cases. The connective tissue itself and its removal had no detrimental effects on the round window membrane. Postoperative computed tomography scan showed no electrode dislocation. Mean postoperative word recognition score after 3 months was 57.4% (± 17.2%) and improved significantly to 73.1% (± 16.4%, P = .005) after 2 years. Conclusion: Performing CI after preceding ExT, connective tissue has to be expected blocking the round window niche. Remaining tissue can be removed safely and does not alter the round window membrane allowing for a proper electrode insertion. Short- and long-term hearing results are satisfactory. Consequently, ExT with sealing of the round window membrane in patients with sudden sensorineural hearing loss does not impede subsequent CI that can still be performed safely.

Bilateral Sensorineural Hearing Loss

AbstractBackground:Bilateral sensorineural hearing loss associated with recurrent urticarial skin lesions may be signs of underlying Muckle–Wells syndrome. Previous reports have described the hearing loss to be progressive in nature.Method:To our knowledge, this paper presents the first published case of sudden onset, bilateral sensorineural hearing loss associated with urticarial vasculitis due to underlying Muckle–Wells syndrome.Results:The patient underwent a cochlear implantation with a modest outcome.Conclusion:Cochlear implantation may help to rehabilitate sudden hearing loss associated with this condition, but early diagnosis may allow treatment with interleukin-1β inhibitors such as anakinra.

AbstractObjective:To present the first published case of a child with bilateral profound sudden sensorineural hearing loss found in association with sickle cell anaemia, and to demonstrate the importance of early recognition, investigation and empirical treatment of sudden sensorineural hearing loss.Method:Case report and review of world literature.Case report:The authors present the case of a seven-year-old child with known sickle cell anaemia, who presented with bilateral profound sensorineural hearing loss developing over a period of five days. There was a history of ophthalmological disease in the preceding weeks, and inflammatory markers were raised. The differential diagnosis included a vaso-occlusive or inflammatory aetiology such as Cogan's syndrome, and treatment for both was instigated. Hearing thresholds did not recover, and the patient underwent cochlear implantation 12 weeks later.Conclusion:Sudden sensorineural hearing loss has a variable aetiology and is rare in children. Immediate treatment for all possible aetiologies is essential, along with targeted investigations and early referral for cochlear implantation if no recovery is demonstrated.

Background: Bacterial meningitis is one of the major factors in the etiology of acquired sensorineural hearing loss in children and adults. Cochlear implantation in these patients is challenging because of inner ear ossification and fibrosis, and this procedure sometimes achieves poorer outcomes in this scenario than with other causes of sensorineural hearing loss. There has been little research into the factors affecting the outcomes of this procedure. Objective: To evaluate the outcomes of cochlear implantation in patients with postmeningitis profound sensorineural hearing loss and to evaluate the factors that affect the results. Materials and Methods: A retrospective review was conducted of thirty patients who were diagnosed with post meningitis profound hearing loss and underwent cochlear implantation at Rajavithi Hospital between 2001 and 2016. Preoperative language status, duration of deafness, preoperative imaging, and degree of electrode insertion were recorded. Categories of auditory performance-II test (CAP-II) was evaluated in all cases, one year postoperative. Results: Thirty postmeningitis deafness patients underwent cochlear implantation. The median age at diagnosis of meningitis and age at implantation were 41 years (range 1 to 75) and 49.50 years (range 3 to 75), respectively. The median duration of deafness was 12 months (range 4 to 300), and the overall mean CAP-II at one year after surgery was 5.47±2.21. The postlinguistic group had a significantly higher CAP-II score than the prelinguistic one (p=0.006). Electrodes were successfully totally inserted in 19 patients (63.3%) and partially inserted in 11 (36.7%). The average CAP-II score in the group with fully-inserted electrodes was significantly higher than in the group with partially-inserted electrodes (p=0.045). There was no correlation between CAP-II score and age at meningitis diagnosis (p=0.069), age at time of surgery (p=0.105), duration of deafness (p=0.506), or preoperative CT (p=0.228) or MRI abnormality (p=0.078). Conclusion: Cochlear implantation in patients with postmeningitis profound hearing loss had high success rates and favorable outcomes. Preoperative language status and degree of electrode insertion were factors that affected auditory performance results.
