Audiogram construction using frequency-specific auditory brainstem response (ABR) thresholds.

Brainstem evoked response audiometry (ABR) permits auditory pathway assessment without the need for voluntary response. Brainstem responses are unaffected by attention, drugs, and most other confounding conditions. Consequently, if ABR could be used to determine hearing threshold in the speech frequencies, it would have great value for patients who are unable or unwilling to respond accurately during behavioral audiometric testing. Utilizing broad band clicks, one can only estimate hearing sensitivity in the frequency range of 2,000 to 4,000 Hz. This is inadequate for medical or legal purposes in which hearing in the speech frequencies must be assessed. Consequently, we have developed a modified ABR technique that permits a more accurate determination of hearing threshold at 500, 1,000, 2,000 and 3,000 Hz, as illustrated in tests on 27 normal ears. This technique has great potential value for neonatal and mentally handicapped populations, as well as for individuals involved in hearing loss litigation.

Voice abnormalities in short stature syndromes.

Patients with short stature have a high incidence of voice and laryngeal abnormalities. In sixteen patients with short stature of various etiologies, these abnormalities appeared to be unrelated to hearing loss or other otolaryngologic problems. However, in many patients they were associated with typical symptoms and signs of voice abuse. Physicians and speech-language pathologists caring for patients with short stature should be alert for voice problems, and should consider instituting early voice education, diagnosis and treatment.

Vocal tract response to toxic injury: clinical issues.

Toxic substances commonly affect the voice. In many cases, the mechanism of toxicity is unknown. Treatment is often based on intuition, rather than scientific fact. Extensive collaborative research is needed.

Endoscopic management of a giant cholesterol cyst of the petrous apex.

Giant cholesterol cyst (GCC) of the petrous apex is a rare clinical entity. This benign cystic lesion can cause neurologic deficits and vascular compromise by persistent growth and progressive bone destruction. Magnetic resonance imaging studies of GCC show the lesions to be hyperintense on T(1)-weighted sequences with progressively lower signal intensities on the first and second echoes of T(2)-weighted sequences. These findings are relatively specific for GCC, permitting a narrow differential diagnosis. The goal of surgery is to provide adequate drainage with the creation of a permanent fistula. The classic approaches to these lesions are the posterior fossa craniotomy and the middle fossa extradural craniotomy. The translabyrinthine approach provides wide exposure at the expense of cochlear and vestibular function. The transsphenoidal approach provides adequate drainage with hearing preservation and no craniotomy. The endoscopic, endonasal transsphenoidal approach to a 2.5 cm GCC of the petrous apex accomplished complete drainage with the creation of a fistula. Advances in endoscopic technique and instrumentation facilitated the addition of the approach to the surgeon's armamentarium. In selected cases, this approach provides adequate surgical exposure with minimal morbidity.

Evaluation and treatment of the unilateral paralyzed vocal fold.

The evaluation and treatment of patients with unilateral vocal fold paralysis have evolved as improvements in objective measurements of phonatory function and new modalities for treatment have developed. A thorough history, physical examination, subjective voice evaluation, objective voice analysis, and electromyography are used to make a diagnosis, determine the cause, and plan treatment. The goal of treatment of the patient with a unilateral vocal fold paralysis is to restore normal phonatory function without aspiration. Multiple modalities have developed to allow for restoration of nearly normal phonatory function, and these include voice therapy alone or in combination with injection medialization, laryngoplastic phonosurgery, or laryngeal reinnervation. Otolaryngologists should be familiar with the incidence, cause, evaluation, and state-of-the-art treatment of unilateral vocal fold paralysis of optimize patient care and avoid suboptimal results often seen with antiquated or inappropriate treatment.

Arytenoid dislocation: diagnosis and treatment.

Disruption of the cricoarytenoid joint is a relatively uncommon event, according to the world literature. Only 31 reported cases of arytenoid dislocation or subluxation exist other than the 26 cases described in this paper. Often cases are misdiagnosed as vocal fold paralysis. Knowledge of the signs and symptoms of arytenoid dislocation aids in correct diagnosis and early treatment. Even when diagnosis has been delayed, surgery may be highly effective. Familiarity with state-of-the-art diagnostic techniques and new concepts in management helps optimize the chances for good voice quality.

Lyme disease: a review for the otolaryngologist.

Lyme disease is an important consideration in the differential diagnosis of patients seen by the otolaryngologist. Facial paralysis is the most common sign. The otolaryngologist may also see patients with temporal mandibular joint pain, cervical lymphadenopathy, facial pain, headache, tinnitis, vertigo, decreased hearing, otalgia and sore throat. The incidence is increasing and known to be endemic to certain areas of the United States and abroad. This paper reviews the various ways Lyme disease appears to the otolaryngologist. Three cases along with a discussion including epidemiology, vector, animal host relationship, clinical manifestations and pathophysiology are included. The literature is reviewed and the treatment discussed.
