Abstract

Objective: To study over time correlations between Compound Action Potential measured through Neural Response Imaging (NRI) and electrically Evoked Stapedius Reflex Thresholds (eSRT) and psychophysical measurements to develop guidelines for using those objective measures to optimize HiRes programs in patients implanted with Advanced Bionics CII-Bionic Ear or a HiRes90K cochlear implants.

Patients: Fifteen pediatric subjects, all implanted with a CII-Bionic Ear or a HiRes90K.

Interventions: NRI was measured on 4 electrodes intraoperatively at first fitting and after 3, 6, and 12 months of use. eSRT recordings were performed intraoperatively with SoundWave speech bursts. Subjects were fitted using the SoundWave defaults. Relationships between NRI thresholds (tNRI), eSRT, and most comfortable levels (M) are presented.

Main Outcome Measures: Intraoperative eSRT, and intraoperative and postoperative tNRI at each fitting session. Auditory performance measured by Categories of Auditory Performance and Meaningful Auditory Integration Scale.

Results: First fitting Ms are 97% of intraoperative tNRI; stable Ms (12 months of implant use) are equal to 115% of 12 months' tNRI and to 76% of intraoperative eSRT on average across the electrode array with great intersubject variability.

Conclusion: The results show that single-channel tNRI and eSRT values can be clinically useful for programming cochlear implants in children, although this should be done with caution as there is considerable interpatient variability.

Abstract

Objectives. Surgery for otosclerosis has a highly satisfactory hearing outcome, for both the patient and the otologic surgeon. However, subsequent conductive hearing loss, dizziness/vertigo, or sound distortion could necessitate revision surgery. The aim of the present study is to evaluate the surgical findings and hearing outcomes of 84 revision stapes surgeries.

Study Design. Case series with chart review.

Setting. Tertiary referral center. Subjects and Methods. At our institution, 84 revision cases were performed between 1998 and 2009. Conductive hearing loss was the revision indication in 69 cases, severe dizziness/vertigo in 8 patients, sound distortion in 5 cases, and progressive hearing loss with dizziness in 2 patients. Operative findings were noted in every case and evaluated separately.

Results. Surgical intervention revealed problems related to prosthesis in 51 cases, fibrotic bands in 26 cases, adhesions in 13 cases, incus necrosis in 15 cases, perilymphatic fistula in 3 cases, intact footplate in 5 cases, incus-malleus fixation in 2 cases, and reobliteration in 2 cases. Mean follow-up period was 19 months (range, 12-53 months). Successful hearing results (air-bone gap <0 dB) were reached in 58% of the cases, and satisfactory hearing results (air-bone gap <20 dB) were reached in 71% of the cases.

Conclusions. The ideal patient for revision stapes surgery is one who benefits from the initial surgery but complained of conductive hearing loss. In the present study, improvement in pure-tone average was 13.2 dB, and the mean air-bone gap was 9.6 dB.

Abstract

Pleomorphic adenoma is mixed and usually benign tumor originating salivary glands. The most common salivary gland tumor is pleomorphic adenoma. The most common localization of pleomorphic adenoma is parotid gland. Although it is found in major salivary gland, pleomorphic adenoma may be found paranasal sinuses and nasal cavity rarely. A 74-year-old female presented with a 3-month history of right-sided nasal obstruction was presented. Although it is infrequently, the possibility of pleomorphic adenoma should be kept in mind while assessing well-defined lobular intranasal lesions.

Abstract

INTRODUCTION: Electromagnetic middle ear implants which had been originally used in patients with high frequency hearing losses with normal middle ear conductive mechanism, recently were begun to be used on patients with defective or absent ossicles. Round window application of transducer of electromagnetic implant, first used by Colletti seems to be promising in such patients.

OBJECTIVES: In this study indications and a modified technique of round window attachment of an electromagnetic implant (Vibrant Sound Bridge) are presented, and results obtained on 5 patients are discussed.

MATERIALS AND METHODS: All patients had been implanted at Izmir Teaching and Research Hospital on 2007 - 2008. All cases were formerly operated in various centers because of cholesteatoma and all but one found to be free of residual or recurrent cholesteatoma during surgery. In all cases floating mass transducer has been applied onto the round window membrane in a perichondrial envelope. Patients were switched on 4-6 weeks after surgery.

RESULTS: Pre-op AC levels were between 65-85 db (median 69.3) and BC levels were between 10. 1-60db (median 33.7). SDS scores were between 46-95 % (median 77.3) In all patients we have not seen any detoriation in these values after surgery. After switch on hearing thresholds with implant were elevated near to BC levels. SDS scores were considerably better in all patients (median 83) after surgery.
