Osseointegrated Auditory Devices-Transcutaneous: Sophono and Baha Attract.

Percutaneous osseointegrated bone conduction auditory devices provide excellent auditory rehabilitation. Device-related complications relate to skin abutment interface and cosmetic concerns, resulting in the development of transcutaneous devices. The Sophono and Baha Attract are safe and considered cosmetically superior to the percutaneous Baha Connect and Ponto.

Osseointegrated Auditory Devices: Bone-Anchored Hearing Aid and PONTO.

Osseointegrated auditory devices (OADs) are hearing devices that use an external receiver/processor that stimulates bone conduction of sound via a titanium prosthesis that is drilled into the bone of the cranium. Since their introduction in 1977, OADs have undergone substantial evolution, including changes in manufacturing of the implant, improvements in the external sound processor, and simplification of implantation techniques. Expansion of criteria for patient candidacy for implantation has occurred corresponding with changes in the implants and processors.

Metastatic squamous cell carcinoma of the tonsil presenting as otorrhea: a case report.

We describe the case of a 52-year-old man with a history of squamous cell carcinoma (SCC) of the tonsil who presented with right subacute otalgia and otorrhea. Dedicated computed tomography of the temporal bones showed opacification within the mastoid process with destruction of bony mastoid septations consistent with coalescent mastoiditis. Preoperative imaging showed no destruction or expansion of the bony eustachian tube that would indicate that a direct spread had occurred.

Pilot study of a high-frequency school-based hearing screen to detect adolescent hearing loss.

Objective: Like most of the United States, school-based hearing screening in Pennsylvania focuses on low-frequency, conductive hearing losses typical for young children, rather than the high-frequency, noise-induced hearing loss more prevalent among adolescents. The objective of this study was to compare the sensitivity and specificity of current school hearing screening in Pennsylvania with hearing screening including high frequencies, designed to detect adolescent hearing loss.

Setting: A single public high school.

Round window membrane permeability to golimumab in guinea pigs: a pilot study.

Objectives/hypothesis: Autoimmune inner ear disorder is one of a few types of sensorineural hearing loss that is treatable and potentially reversible. Treatment involves oral steroids and methotrexate. Other treatment modalities have been tried with variable success.

Vestibular pneumolabyrinth: why assessment with temporal bone computed tomography utilizing dynamic focal spot mode is important for the diagnosis.

We present an interesting and relatively uncommon case of vestibular pneumolabyrinth in a young child post-trauma. His initial clinical exam and imaging studies of the head and cervical spine were negative. He subsequently developed nystagmus and a dedicated temporal bone study demonstrated a subtle fracture and vestibular pneumolabyrinth.

Reconstruction of congenital microtia-atresia: outcomes with the Medpor/bone-anchored hearing aid-approach.

Ideal surgery for congenital microtia-atresia would offer excellent cosmetic and hearing rehabilitation, with minimal morbidity. Classic approaches require multiple procedures, including rib cartilage harvest and aural atresia repair. Our facial plastic and otologic team approach incorporates a high-density porous polyethylene (Medpor, Porex Surgical, Newnan, GA) auricular framework, followed by single-stage bone-anchored hearing aid (BAHA) implantation.

Successes and complications of the Baha system.

Objective: To determine the incidence and type of complications, as well as patient satisfaction, associated with the Baha system.

Study Design: Retrospective case review.

Setting: The Silverstein Institute, Sarasota, Florida, and the Columbia University Medical Center, New York, New York.

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.

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.

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.

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.

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.

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.
