An update on the surgical treatment of Ménière's diseases.

Various surgical procedures have evolved for the treatment of Ménière's disease patients who are refractory to medical therapy. These can be in the form of conservative surgeries as in endolymphatic sac surgery or in the form of destructive procedures. The latter include labyrinthectomy and vestibular nerve section, which result in deafferentation of the vestibular end organ. In the past decade, intratympanic therapy with gentamycin and steroids has evolved as new methods for the treatment of Ménière's disease. The literature witnesses controversies in the effectiveness of endolymphatic sac surgery in the treatment of Ménière's disease. The choice of the surgical procedure depends on the degree of serviceable hearing, the severity of the spells, and the condition of the contralateral ear. The most commonly used procedures in the treatment of Ménière's disease and their indications are reviewed.

Localization by unilateral BAHA users.

OBJECTIVES: Patients with unilateral hearing loss report difficulty hearing conversation on their impaired side, localizing sound, and understanding of speech in background noise. The bone-anchored cochlear stimulator (BAHA) (Entific, Gothenburg, Sweden) has been shown to improve performance in persons with unilateral severe-profound sensorineural loss (USNHL). The purpose of this study is to evaluate the effectiveness of BAHA in sound localization for USNHL listeners. STUDY DESIGN: Prospective study of 12 USNHL subjects, 9 of whom received implants on the poorer hearing side. A control group of 10 normal hearing subjects were assessed for comparison. Localization with and without BAHA was assessed using an array of 8 speakers at head level separated by 45 degrees. Error analysis matrix was generated to evaluate the confusions, accuracy in response, and laterality judgment. RESULTS: The average accuracy of speaker localization was 16% in the unaided condition, with no improvement with BAHA use. Laterality judgment was poorer than 43% in both aided and nonaided conditions. CONCLUSIONS: Patients with UNSNHL had poor sound localization and laterality judgment abilities that did not improve with BAHA use.

High-frequency pulsed electromagnetic energy in tinnitus treatment.

OBJECTIVES/HYPOTHESIS: Electromagnetic therapy has been used with reported success in multiple clinical settings, including the treatment of seizure disorders, brain edema, migraine headaches, revascularization of burn wounds, and diabetic ulcers. The purpose of the study was to investigate the effect of pulsed high-frequency electromagnetic therapy on chronic tinnitus. STUDY DESIGN: A randomized, prospective, double-blind, placebo-controlled pilot study was conducted to evaluate the effectiveness of high-frequency pulsed electromagnetic energy using the Diapulse device in the treatment of chronic tinnitus. Thirty-seven adult patients with chronic tinnitus of at least 6 months' duration were recruited and randomly assigned to either a treatment or a placebo group. METHODS: Patients received 30-minute treatments with the Diapulse device three times a week for 1 month. The unit was set to deliver electromagnetic energy at a frequency of 27.12 MHz at a repetition rate of 600 pulses per second. All subjects had pretreatment and post-treatment audiological testing, including tinnitus frequency and intensity matching. They responded to a tinnitus rating questionnaire and the Tinnitus Handicap Inventory before and after treatment. RESULTS: There was no significant change in the pretreatment and post-treatment audiometric thresholds in either group. There were no significant differences between the pretreatment and post-treatment Tinnitus Handicap Inventory scores or the tinnitus rating scores in either subject group (Student t test). No diagnosis-specific differences were identified. CONCLUSION: High-frequency pulsed electromagnetic energy (Diapulse) at the settings used in the study showed no role in the therapy of patients with chronic tinnitus.

Transcranial contralateral cochlear stimulation in unilateral deafness.

OBJECTIVES: The purpose of this study is to evaluate the effectiveness of Bone Anchored Cochlear Stimulator (BAHA) in transcranial routing of signal by implanting the deaf ear. Study design and settings Eighteen patients with unilateral deafness were included in a multisite study. They had a 1-month pre-implantation trial with a contralateral routing of signal (CROS) hearing aid. Their performance with BAHA was compared with the CROS device using speech reception thresholds, speech recognition performance in noise, and the Abbreviated Profile Hearing Benefit and Single Sided Deafness questionnaires. RESULTS: Patients reported a significant improvement in speech intelligibility in noise and greater benefit from BAHA compared with CROS hearing aids. Patients were satisfied with the device and its impact on their quality of life. No major complications were reported. Conclusion and significance BAHA is effective in unilateral deafness. Auditory stimuli from the deaf side can be transmitted to the good ear, avoiding the limitations inherent in CROS amplification.

Evolving applications in the use of bone-anchored hearing aids.

The bone-anchored hearing aid (BAHA) is an effective means of intervention, its use being well documented in persons with chronic conductive pathology and congenital aural anomalies. This article describes the standard guidelines (both auditory and extraauditory aspects) for patient selection and expands the criteria to include bilateral BAHA implantation, unilateral conductive hearing loss, and unilateral profound sensorineural hearing loss. The BAHA's development, design features, and patient outcomes are also reviewed. Suggestions are presented for fitting, counseling, and following BAHA users.

Oral-facial-digital syndrome type II variant associated with congenital tongue lipoma.

We report a case with several congenital anomalies, including polysyndactyly, hypertelorism, partial median cleft of the upper lip, and 2 solitary tongue masses. These features are consistent with oral-facial-digital (OFD) type II syndrome. This case, however, had tongue lipomas with pathosis instead of the usually described tongue hamartomas. In addition, our patient had a sacral dermal pit, which is not a known characteristic of patients with OFD type II. The patient had a younger sister with the same anomalies who died at the age of 10 days and thus was unavailable for examination. We propose to distinguish patients with tongue lipomas and features of OFD type II as a variant of that syndrome.
