Subtotal Petrosectomy and Blind Sac Closure of the External Auditory Canal: Single-Center Experience with 44 Cases

Objective:This study aims to share our experiences with subtotal petrosectomy, cavity obliteration, and blind sac closure of the external auditory canal.Methods:A total of 44 patients who underwent subtotal petrosectomy and cavity obliteration between January 2009 and April 2013 were analyzed retrospectively. Indications of operation, surgical findings, and complications were recorded.Results:Twenty-three male and 21 female patients with a mean age of 42±18 (8-73) years were included in the study. The mean postoperative follow-up period was 22±11 (9-52) months. Seven patients underwent primary cavity obliteration (6 with supralabirentin cholesteatoma and 1 with facial nerve schwannoma; all had total sensorineural hearing loss on the operated side). Obliteration was performed as a secondary procedure in 19 patients who had uncontrolled otorrhea and unserviceable hearing. During the procedure, the implantation processes of a Carina device in 2 patients, active middle ear implant (Vibrant Soundbridge- VSB) in 4 patients, and cochlear implant in 8 patients who had dry mastoidectomy cavities were performed. Removal of the hearing devices was carried out simultaneously with the procedure in 4 patients who had been administered an auditory implant previously. The complications of cerebrospinal otorrhea and mastoid cavity infection developed in 1 patient on the 7th postoperative day. This had been drained under general anesthesia, and recovery was obtained without any problems. Three patients had skin necrosis localized in the external auditory canal, which was repaired under local anesthesia.Conclusion:Subtotal petrosectomy and cavity obliteration procedure can be a good alternative to prevent recurrent infections and cavity problems in patients who have safe cavities with unserviceable hearing. Additionally, it is gaining more popularity in chronic otitis media patients to secure the implant electrode and to prevent cavity infection if they need to be rehabilitated with cochlear or active middle ear implants

The Effect of Insulin Like Growth Factor-1 on Recovery of Facial Nerve Crush Injury

Objectives The aim of this study is to investigate the efficacy of locally applied insulin-like growth factor 1 (IGF-1) on the recovery of facial nerve functions after crush injury in a rabbit model. Methods The rabbits were randomly assigned into three groups. Group 1 consisted of the rabbits with crush injury alone; group 2, the animals applied saline solution onto the crushed facial nerve and group 3, IGF-1 implemented to the nerve in the same manner. Facial nerve injury was first electrophysiologically studied on 10th and 42nd days of the procedure. The damage to the facial nerves was then investigated histopathologically, after sacrification of the animals. Results In the electrophysiological study, compound muscle action potential amplitudes of the crushed nerves in the second group were decreased. In pathological specimens of the first and second groups, the orders of axons were distorted; demyelination and proliferation of Schwann cells were observed. However, in IGF-1 treated group axonal order and myelin were preserved, and Schwann cell proliferation was close to normal (P<0.05). Conclusion Local application of IGF-1 in a slow releasing gel was found efficacious in the recovery of the facial nerve crush injury in rabbits. IGF-1 was considered worthy of being tried in clinical studies in facial nerve injury cases

Audiological Results of Total Ossicular Replacement Prosthesis with Cartilage Shoe Technique

Objective:The aim of this study was to investigate functional results of total ossicular replacement prosthesis (TORP) shaft stabilization with a cartilage shoe in chronic otitis media patients with cholesteatoma who had undergone canal wall down tympanomastoidectomy (CWDT). In addition, it was determined whether the presence of granular and edematous mucosa in middle ear altered functional outcomes.Methods: Sixty patients, who had undergone CWDT with the use of TORP for the reconstruction of ossicular chain, were divided into two groups. Patients with cartilage shoe were classified as Group 1 (n=30) and those without the shoe were classified as Group 2 (n=30). Patients in both groups were classified into “A” and “B” subgroups according to the middle ear risk index (MERI). Air conduction (AC) and bone conduction thresholds were evaluated preoperatively and postoperatively.Results: There was no statistically significant change between preoperative AC thresholds of the groups and subgroups (p>0.05). There were statistically significant differences regarding AC thresholds and air– bone gap (ABG) values between Groups 1 and 2 at the postoperative 12th month (p<0.05). Postoperative AC thresholds and ABG values of Group 1B patients with a high MERI score were statistically significant at all frequencies than those of Group 2B patients (p<0.05). When ABG values were compared, it was observed that functional results were better in Group 1B, but a statistically significant difference was observed only at 2000 Hz (p<0.01).Conclusion: The cartilage shoe method for titanium TORP stabilization that is used for ossicular reconstruction during CWDT has been found to have a beneficial effect on auditory outcomes. Cartilage shoe application increases positive effects on hearing outcomes, particularly if the middle ear mucosa is granular and edematous

Can MRI-induced silastic casing tear be repaired without the need for cochlear implant replacement?

WOS: 000482248500032PubMed: 31200318Silastic magnet casing tear of cochlear implant (CI) due to magnetic resonance imaging (MRI) is an uncommon complication. We report repair of a case with magnet dislocation due to MRI-induced silastic casing tear without re-implantation. We believe that this repair method, which has not been previously defined in the literature, will be interesting and guiding

Long term results and evaluation of device satisfaction in patients used the vibrant sound bridge (VSB)

Atsal, Gorkem/0000-0001-6184-8564WOS:000614165500001PubMed: 33528309Background Patients' satisfaction with the device is as important as the audiological gains in patients using these devices. Objective in this study, we aimed to evaluate the hearing aid satisfaction of individuals using The Vibrant Sound Bridge (VSB) (Vibrant Med-El, Innsbruck, Austria) and to compare this result with audiologic results with and without devices. Material and methods Patients who were using VSB were included in the study. Preoperative and postoperative pure tone averages and demographic datas of the patients to be included in the study were recorded. A shortened version of Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaire, was used to evaluate patients' device satisfaction. Results Fifteen patients with VSB were included in the study. The mean follow-up was 9.13 years. The preoperative air conduction threshold and the air-bone gap in all frequencies were significantly higher than postoperative values (p < .05). The functional gain was found as 28 dB. in the APHAB questionnaire, there was a significant difference between total score results and EC, BN, RV subscales in the patients using the device (p < .01). Conclusion and significance Patients with VSB give satisfactory results in auditory gains. in particular, good indication and long-term use of the device increases the suitability and satisfaction of the patients.7th edition of Dubai Otology, Neurotology & Skull Base Surgery Conference 2019 DubaiThis manuscript has been submitted 7th edition of Dubai Otology, Neurotology & Skull Base Surgery Conference 2019 Dubai
