fa ضرورت نیاز به تجدید ارزیابی پروتکل‌ سندرم‌ها: نتایج ABR در یک کودک مبتلا به سندرم Noonan شنوایی شناسی Audiology گزارش مورد Case Report <div style="text-align: justify;"><span style="font-family:times new roman;">55 years after discovering NS, there was not even one publication regarding the use of auditory electrophysiological tests for analyzing the central auditory nervous system in NS patients. This is an attempt to attract attention of scientists and clinicians in using AEPs for evaluating the function of CANS in NS. Readers can find a report about the results of audiological tests and auditory brainstem response (ABR) findings in a 5-year old Malay boy with NS. It should be noted that he could only produce a few meaningful words. The results of audiological tests showed bilateral mild conductive hearing loss at low frequencies. ABR recordings showed good waveform morphology but the results were atypical. That is, absolute latency of wave V was normal but interpeak latencies of waves I-V, I-II, II-III were prolonged. Conversely, interpeak latency of waves III-V was abnormally shorter.&nbsp;<br> Abnormal ABR results are possibly due to an abnormal anatomical condition or abnormal function of brainstem and might cause speech delay.</span></div> Auditory brainstem response (ABR), Hearing loss, Speech delay, Noonan Syndrome 68 73 http://fdj.iums.ac.ir/browse.php?a_code=A-10-27-1&slc_lang=fa&sid=1 Bahram Jalaei بهرام جلائی 1003194753284600562 1003194753284600562 Yes Audiology Group, School of Rehabilitation Sciences, Iran University of Medical Sciences, Tehran, Iran گروه شنوایی‌شناسی، دانشکدۀ علوم توانبخشی، دانشگاه علوم پزشکی ایران، تهران، ایران Mohamad Normani Zakaria محمد نورمانی‌ذکریا 1003194753284600563 1003194753284600563 No Audiology Program, School of Health Sciences, University of Sains, Kelantan, Malaysia گروه شنوایی‌شناسی دانشکدۀ علوم بهداشت، دانشگاه سینز مالزی، کلانتان، مالزی
