11/19. Detection of aminoglycoside ototoxicity by high-frequency auditory evaluation: selected case studies.

    A practical monitoring procedure utilizing frequencies higher than those tested by conventional audiometry for the detection of ototoxicity has the potential for preventing or minimizing irreversible communication deficits in patients receiving aminoglycoside antibiotic therapy. If ototoxicity produced by these drugs could be detected before it progresses to involve the frequencies essential for communication, it might be possible to lower the dose or to change to another antibiotic to prevent a permanently handicapping hearing impairment. From a total of 77 patients monitored by serial audiograms, three case studies illustrate the various types of auditory sensitivity changes observed with high-frequency audiometry. Ototoxicity was generally detected by high-frequency auditory testing before it could be detected by conventional audiometric procedures. These cases demonstrate the utility of monitoring audition at frequencies higher than those tested conventionally in patients receiving aminoglycoside antibiotics.

12/19. Fibrous dysplasia: a review of the disease and its manifestations in the temporal bone.

    Fibrous dysplasia is a fairly common, localized misdifferentiation of the bone-forming mesenchyme affecting a single or many bones, in which skeletal aberrations represent the cardinal feature, but in which certain endocrinopathies, abnormal pigmentation of skin and mucous membrane, and occasionally other abnormalities form part of the entire disease process. The craniofacial skeleton is one of its predilective sites and therefore the temporal bone may become involved. In such instances the disease manifests itself with 1) progressive loss of hearing, 2) increasing obliteration of the external ear canal, and 3) enlargement and distortion of the temporal bone. The first part of this communication is concerned with a review of the clinical and pathological aspects of the disease in general. The second part is concerned with a discussion of the clinical manifestations in the temporal bone, based upon analysis of the entire literature and the authors' personal experience. The indications for surgical intervention include 1) maintenance of a normal outer ear canal, 2) preservation of cochlear and vestibular function, and 3) prevention of secondary complications.

13/19. Pathophysiological effects of mobius syndrome on speech and hearing.

    The effects of mobius syndrome (MoS) on the functioning of the peripheral speech and hearing mechanisms has not hithertofore been described, to my knowledge. Speech and hearing function of an 8-year-old MoS speaker was studied. Data were obtained from several sources. These included: electromyography of the facial muscles, physical examination of the peripheral speech mechanism, speech and language test batteries, audiological evaluation, and acoustic analyses of the speech signal. A pathologic condition was found to exist in a number of cranial nerves and in structures in the oral cavity. This resulted in consonant and vowel misarticulations, which notably affected speech intelligibility. Middle ear dysfunction was also present. Neurological mechanisms are discussed to account for these pathologies in human communication. Strategies for speech therapy and future research in MoS are presented.

14/19. Communicative disorders. The first year of life.

    Disorders of communication have high incidence and prevalence in the fetus, neonate, and infant, and optimal care is dependent on early recognition and intervention. This article reviews receptive disorders, expressive disorders, and their diagnoses.

15/19. Cochlear dysplasia and meningitis.

    Congenital dysplasias of the labyrinth of the inner ear are associated with varying degrees of hearing loss. There is a risk of a fistulous communication between the subarachnoid space and the middle ear cavity in some cases that present either as cerebrospinal fluid otorhinorrhea or as recurrent attacks of meningitis. The types of deformity where such a fistula is likely have not been clearly defined. The authors correlated the hearing state with the imaging assessment in 20 patients with congenital malformation of the labyrinth and, in particular, the cochlea. In addition the postmortem histologic findings from one patient with severe cochlear dysplasia who died from otogenic meningitis are described. The key to the assessment is the basal turn of the cochlea. If the basal turn is present and of normal caliber then some hearing is possible and there is no risk of a major fistula. However, if the basal turn is wider than normal or replaced by an undeveloped sac then there is anacusis and very real risk of fistula. In such cases the deformed labyrinth needs to be packed with fibrofatty tissues after just one attack of meningitis.

16/19. learning disabilities and central auditory dysfunction.

    hearing loss, whether peripheral or central, compounds the communication and educational problems of the learning disabled student. A central auditory processing disorder uniquely interferes with both the input and integration of verbal information, further resulting in a potentially permanent cognitive dysfunction during the developmental period of acquisition of language. Illustrative cases are presented that indicate the panorama of cognitive dysfunction associated with the learning disabled status. methods of evaluation and identification and diagnostic criteria are correlated with auditory, visual, and academic performance. Comments regarding clinical awareness, prompt recognition, and ensuing individualized remediation are submitted.

17/19. Video otoscopy in audiologic practice.

    Recent advances in endoscopic optics and miniature video camera technology have made video otoscopy (VO) accessible to audiologists in a practical way. Seven categories of VO applications are presented with clinical examples: (1) general examination of the earcanal and tympanic membrane, (2) physician communication/telemedicine, (3) hearing instrument selection and fitting applications, (4) patient education, (5) scope of practice reinforcement, (6) knowledge base/skill growth, and (7) cerumen management.

18/19. Newborn hearing screening in hawaii.

    hawaii has been a pioneer and national leader in implementing universal newborn hearing screening. In fact, hawaii is one of only two states (rhode island is the other) which have a statewide newborn hearing screening program in which 95% or more of all newborns are screened. hawaii is the best example of a truly integrated system of services to provide effective intervention for all infants and toddlers who are identified as having a hearing loss. The success of the newborn hearing screening program is measurable in two ways: 1) all available information indicates that not a single infant with hearing loss has been missed by the screening process and not a single infant has been misdiagnosed as having a hearing loss; and 2) many of the children identified with hearing loss by the newborn hearing screening program have transitioned out of the early intervention program with age-appropriate developmental and communication skills. The success of hawaii's program is a tribute to the enthusiastic support and collaboration of legislators, pediatricians, hospital staff, and DOH personnel.

19/19. Pervasive developmental delay in children presenting as possible hearing loss.

    OBJECTIVE/HYPOTHESIS: Children who fail to develop adequate language skills and/or appropriate social skills by age 2 years often are referred to the department of otolaryngology for otolaryngologic examination and evaluation of possible hearing deficits. Discovering a gross disparity between hearing function and language ability often uncovers an underlying developmental disorder satisfying criteria for diagnosis on the spectrum of autism and pervasive developmental delay (PDD). The otolaryngologist has a unique opportunity to identify these autistic children and initiate their evaluation and management. STUDY DESIGN: Retrospective review. methods: review of charts of children referred over the past 4 years to the Department of otolaryngology for possible hearing loss identified 15 children who were later diagnosed with PDD. RESULTS: Fifteen children initially referred for hearing evaluation were subsequently identified with a diagnosis of PDD. Males outnumbered females 4 to 1, with the average age of referral being 2 years. One third of the patients displayed middle ear disease that improved with PE tube placement. One third of the patients showed brainstem conduction dysfunction on auditory brainstem evoked response testing. CONCLUSIONS: Children with developmental delays, especially higher functioning ones, may present with a myriad of language and communication deficits that are often mistakenly attributed to hearing loss. Otolaryngologists and audiologists can assist in their early identification and appropriate referral for therapy.
