    Abstract Acoustic reflex latency (ARL) has been suggested as an indicator in otoneurological diagnosis. However, limited normative data are available. Conflicting evidence exists regarding the effect of stimulus parameters such as frequency on ARL. In addition, there has been little research investigating the effects of ipsilateral and contralateral stimulation on ARL. In view of these problems, ARL was measured in 30 normal-hearing subjects using 500, 1000, 2000, 4000 Hz tones, low-pass noise, high-pass noise, broadband noise and clicks as activating stimuli. Six parameters of ARL: 10%-on latency, 90%-on latency, 10%-off latency, 90%-off latency, rise time and fall time, were recorded using computerized equipment and analyzed in correlation to the activating frequency and intensity. This study indicated that 500 Hz, 1000 Hz tones, and band noise were more effective in eliciting measurable ARL, whereas 4000 Hz tone and click produced a low percentage of measurable ARL. ARL was shown to increase as the stimulus frequency increased and stimulus intensity decreased. No statistically significant differences were found between the ipsilateral ARL and contralateral ARL.

    Abstract The role of the laryngeal reflex in glottal movement has been reported, but its mechanism remains unclear. To further investigate the neurophysiological characteristics of glottal movement, we recorded the laryngeal reflexomyographic responses (LRMRs) to electrical stimulation of the superior laryngeal nerve (SLN) in rabbits. The procedure involved simultaneous recording of the LRMRs from the thyroarytenoid muscles by means of bipolar hooked wire electrodes after electrical stimulation to the SLN. The results demonstrated characteristic patterns of the responses, consisting of R1 and R2, similar to those found in humans. The R1 response was obtained with a latency of 10.7 +/- 0.78 ms. The ipsilateral R2 response was obtained with a latency of 43.76 +/- 4.67 ms in all rabbits, and the contralateral R2 response with a latency from 42.6 to 50.2 ms in 4 rabbits. It was concluded that LRMRs may serve as a potential central laryngeal function test in the investigation of glottal movement control.

    Abstract Objective: The purpose of this study is to investigate the clinical aspects of profound hearing loss (PHL) and their significance for defining deafness.
    Methods: The audiological data were reviewed from 3660 patients who were evaluated in the Otolaryngology Clinic at Louisiana State University in Shreveport, LA, over a 5-year period. The medical charts from the patients were also reviewed for the information of medical diagnosis, surgical records and radiological findings.
    Results: There were 34 patients identified with bilateral PHL or deaf, 177 patients with unilateral PHL and 123 patients with borderline PHL. Congenital hearing loss and unknown-cause hearing loss in this series were predominant with 267 cases (79.9%). A surgical management was indicated in 39 cases (11.7%) including middle ear infection, ossicular chain abnormalities and auditory nerve/brainstem tumors.
    Conclusion: This study suggests that audiometrically PHL should be thoroughly evaluated to detect reversible or remediable conditions by surgical and medical approaches. The diagnosis of deafness should be confirmed by an integration of the audiological data and medical documents including surgical and radiological findings. Aural rehabilitation program should be designed for deaf patients with varied etiology and degree of residual peripheral hearing sensitivity following medical clearance.

    Abstract A comprehensive audiologic study of a family with Noonan syndrome is reported together with a review of 20 cases of this syndrome with regard to hearing sensitivity and middle ear status. An incidence of progressive sensorineural hearing loss at the high frequencies is found for 50% of the ears. It is emphasized that early audiologic management may improve the quality of life for patients with Noonan syndrome.

    Abstract Purpose: The purpose of this study was to characterize the relation of different ordinal patterns of transient otoacoustic emissions (TEOAES) with respect to underlying otologic disorders and auditory status.
    Patients and methods: The results of TEOAEs in 225 patients with various auditory disorders were investigated and compared with normative data established from 90 subjects of various ages. TEOAEs were categorized according to four patterns: (1) normal (general response level within 90% of normative data, (2) reduced amplitude (general response level was > or =2 dB peak sound pressure level (pSPL), but less than the mean -1.64 SD of the normative data), (3) abnormal morphology of frequency spectrum (general response level was within normal limits, but reduced at > or =2 individual octave frequencies between 1,000 and 5,000 Hz), and (4) total absence (response level <2 dB pSPL).
    Results: This study showed that the normal pattern of TEOAEs, in terms of response amplitude, varied with age. Our results further indicated that a reduced amplitude pattern of TEOAEs was noted in patients with a mild sensorineural hearing loss (SNHL), negative tympanometric pressure, a pressure-equalization tube, and Meniere's disease. TEOAEs provided good frequency-specific information for patients with a noise-induced hearing loss. All patients with ossicular chain abnormalities, more than moderate SNHL, and a middle ear mass or effusion had total absence of TEOAEs. Patients with acoustic neuroma and brainstem lesions presented a complex profile of TEOAEs. In the follow-up of auditory function in patients undergoing otologic surgery, different patterns of TEOAEs between the preoperative and postoperative recordings were evident, which correlated with the hearing thresholds and middle ear status. The abnormal findings of TEOAEs due to specific auditory diseases were discussed.
    Conclusion: The interpretation of TEOAEs can be facilitated through an analysis of specific patterns and in combination with other audiologic tests.

    Abstract Laryngeal electromyography (LEMG) is clinically valuable in the evaluation of laryngeal dysfunction and vocal fold immobility. To facilitate clinical application of this electrophysiologic test, a detailed description of modified LEMG techniques is presented. The techniques were applied for simultaneous bilateral recordings of the thyroarytenoid, cricothyroid, and posterior cricoarytenoid muscles. The basic patterns of LEMG are classified into three different types: normal, neuropathy, and myopathy. In an attempt to characterize these patterns, we have reported eight LEMG-documented cases: unilateral laryngeal paralysis, bilateral laryngeal paralysis, cricoarytenoid joint dislocation, cricoarytenoid joint ankylosis, laryngeal myopathy, pharyngeal paralysis (soft palate paralysis), spasmodic dysphonia, and unilateral laryngeal paralysis with anastomosis. The significance of the major LEMG patterns is discussed.

    Abstract Laryngeal joint injury or arytenoid dislocation is not an uncommon complication resulting from intubation trauma, and is best evaluated by laryngeal electromyography (EMG) combined with laryngoscopic examinations. Two cases of cricoarytenoid joint injuries after intubation are reported along with laryngeal EMG findings. Early diagnosis of arytenoid dislocation is important for appropriate surgical management and better prognosis. However, the reported cases, because of delayed referrals, showed prolonged cricoarytenoid joint injuries associated with thyroarytenoid muscle denervation or myopathy, and resultant vocal fold immobility. The results of laryngeal EMG in cricoarytenoid joint injuries can be classified into three different patterns: 1) normal recruitment, 2) myopathy, and 3) denervation or reinnervation of the thyroarytenoid muscles. It is particularly valuable to sample different portions of the thyroarytenoid muscles with EMG in order to evaluate different patterns or pathologic changes of the muscles and nerve paralysis.

    Abstract Otolaryngological examinations, videostroboscopic image analysis, and laryngeal electromyography were used as a test battery for a critical evaluation in 80 patients. Vocal fold movements were categorized into mobility, restricted mobility, immobility with different positions, and overactive movement. Laryngeal electromyographic examinations were conducted in all patients, and the results were classified into normal, neuropathic, and myopathic patterns. The electromyographic data were integrated with videostroboscopic findings, interpreted with knowledge of biomechanical and electrophysiological mechanisms of the larynx, and correlated clinically with underlying diseases. It is suggested that neurolaryngological procedures are most clinically useful when dictated by a decision-making algorithm.
