Background Hearing loss (HL) is commonly found in childrenwith microcephaly. The aim of this study was to reveal hearing lossand auditory brainstem pathways disorders in children with micro-cephaly and other handicaps.Methods There were 194 children who were referred for hearingevaluation. Subjects with history of congenital perinatal infection(TORCH) were excluded. Data were collected from the results ofBrainstem Auditory Evoked Potentials (BAEP) recordings, includ-ing sex, age, clinical manifestations, latency and interlatency be-tween waves I, III, V, and the hearing levels of each ear.Results Moderate to profound HL were found in fourteen ears(58%) of patients with microcephaly. Moderate to profound HL (28%)and endocochlear damage (15%) were found in the ears of pa-tients with microcephaly and delayed speech. Moderate to pro-found HL (39%) and endocochlear damage (11%) were detectedin the ears of patients with microcephaly and delayed develop-ment. Moderate to profound HL (21%) and endocochlear damage(16%) were found in the ears of microcephalic patients with bothdelayed speech and delayed development. Moderate to profoundHL (26%) and endocochlear damage (32%) were detected in theears of patients with microcephaly and cerebral palsy.Conclusion This study revealed the importance of early HL de-tection in microcephalic patients especially those with other handi-caps such as delayed speech, delayed development, and cere-bral palsy

Background: Permanent hearing loss after posterior fossa microvascular decompression (MVD) for typical trigeminal neuralgia (TTN) is one of the possible complications of this procedure. Intraoperative brainstem auditory evoked potentials (BAEPs) are used for monitoring the function of cochlear nerve during cerebellopontine angle (CPA) microsurgery. Level-specific (LS)-CE-Chirp® BAEPs are the most recent evolution of classical click BAEP, performed both in clinical studies and during intraoperative neuromonitoring (IONM) of acoustic pathways during several neurosurgical procedures. Methods: Since February 2016, we routinely use LS-CE-Chirp® BAEPs for monitoring the function of cochlear nerve during CPA surgery, including MVD for trigeminal neuralgia. From September 2011 to December 2018, 71 MVDs for TTN were performed in our department, 47 without IONM of acoustic pathways (Group A), and, from February 2016, 24 with LS-CE-Chirp BAEP (Group B). Results: Two patients of Group A developed a permanent ipsilateral anacusia after MVD. In Group B, we did not observe any permanent acoustic deficit after surgery. In one case of Group B, during arachnoid dissection, intraoperative LS-CE-Chirp BAEP showed a temporary lag of V wave, resolved in 5 min after application of intracisternal diluted papaverine (0.3% solution without excipients). Conclusion: MVD is widely considered a definitive surgical procedure in the management of TTN. Even though posterior fossa MVD is a safe procedure, serious complications might occur. In particular, the use of IONM of acoustic pathways during MVD for TTN might contribute to prevention of postoperative hearing loss.

Objective (1) To determine the diagnostic accuracy of tuning fork tests (TFTs; Weber and Rinne) for assessment of hearing loss as compared with standard audiometry. (2) To identify the audiometric threshold at which TFTs transition from normal to abnormal, thus indicating the presence of hearing loss. Data Sources PubMed, Ovid Medline, EMBASE, Web of Science, Cochrane, and Scopus and manual bibliographic searches. Review Methods A systematic review of studies reporting TFT accuracy was performed according to a standardized protocol. Two independent evaluators corroborated the extracted data and assessed risk of bias. Results Seventeen studies with 3158 participants, including adults and children, met inclusion criteria. The sensitivity and specificity of the Rinne test for detecting conductive hearing loss ranged from 43% to 91% and 50% to 100%, respectively, for a 256-Hz fork and from 16% to 87% and 55% to 100% for a 512-Hz fork. The audiometric thresholds at which tests transition from normal to abnormal ranged from 13 to 40 dB of conductive hearing loss for the Rinne test and from 2.5 to 4 dB of asymmetry for the Weber test. Significant heterogeneity in TFT methods and audiometric thresholds to define hearing loss precluded meta-analysis. There is high risk of bias in patient selection for a majority of the studies. Conclusion Variability exists in the reported test accuracy measurements of TFTs for clinical screening, surgical candidacy assessments, and estimation of hearing loss severity. Clinicians should remain mindful of these differences and optimize these techniques in specific clinical applications to improve TFT accuracy.

Brainstem auditory evoked potentials present a unique opportunity to assess the neuronal and auditory status of the newborn. To date, sample data have been few in number, thereby limiting their interpretive value. The present study was undertaken in an effort to accrue data generated from a large sample size. One hundred fifty-five normal neonates were tested within the first 36 hours of life. No subjects qualified for inclusion in the High Risk Register for Hearing Loss established by the American Academy of Pediatrics. Each ear was tested independently, using click stimuli at a rate of 30.1 per second at 65 dB HTL. Test runs were replicated for purposes of reliability. A run consisted of 2,000 sweeps of data, each being 10 ms in length. Identification of wave forms were assessed by two or more observers. Total agreement was required from all observers for inclusion of wave peaks for analysis. Latencies of onset of stimulus to peak were obtained. Descriptive as well as inferential statistics were computed. Results provide standardized data for comparison.
