The aim of this study was to evaluate the hearing parameters of children with migraine during ictal and interictal period.
16 pediatric patients with migraine and normal otolaryngologic examination were evaluated. Hearing parameters were assessed with auditory brainstem response (ABR) testing between and during the migraine attacks. Binaural absolute latencies of waves I, III and V, interpeak latencies I-III, III-V and I-V of ABR in response to 80 dB nHL clicks were calculated. Initial findings were compared with those of 20 healthy volunteers.
Peak latencies of wave V and interpeak latencies of I-V were prolonged during the attack in migraineurs on the left. The side of latency elongation was not affected by the side of headache. When these parameters were separately compared for gender, they were prolonged in boys during the attack in migraineurs; however in girls, while there was statistically significant difference at interpeak latencies of I-V, no significant difference was noted at peak latencies of wave V.
ABR waves did not exceed clinical norms in migraine patients in headache-free period. But, important effects on sensorineural hearing parameters were detected during the attack. Our results indicated a transient impairment of the auditory brainstem function during the headache in pediatric migraine patients.
本研究旨在评估偏头痛患儿发作期和发作间期的听力参数。
对16例偏头痛且耳鼻喉检查正常的儿科患者进行评估。在偏头痛发作期间及发作间期，通过听性脑干反应（ABR）测试评估听力参数。计算对80 dB nHL短声反应时ABR的I、III和V波双耳绝对潜伏期，以及I-III、III-V和I-V波峰间期。将初步结果与20名健康志愿者的结果进行比较。
左侧偏头痛患者发作期V波峰潜伏期和I-V波峰间期延长。潜伏期延长的一侧不受头痛侧的影响。按性别分别比较这些参数时，偏头痛患儿发作期男孩的参数延长；然而在女孩中，虽然I-V波峰间期有统计学显著差异，但V波峰潜伏期无显著差异。
偏头痛患者在无头痛期ABR波未超出临床标准。但是，在发作期检测到对感音神经性听力参数有重要影响。我们的结果表明儿科偏头痛患者头痛发作时听觉脑干功能存在短暂损害。
