ABSTRACT
<p><b>AIM</b>To investigate the change of latency and interpeak latency of each component of BAEP (brainstem auditory evoked potential, BAEP) and its correlation with PV/PFV (pontine volume/posterior fossa volume, PV/PFV) ratio in OPCA (olivopontocerebellar atrophy, OPCA).</p><p><b>METHODS</b>We used Keypoint EMG/EP to determine waves I PL (peak latency, PL), III PL, V PL and I - III IPL (interpeak latency, IPL), III - V IPL, I - V IPL and used 1.5TMR 3D volume rendering software to determine PV (pontine volume, PV), CV(cerebellar volume, CV) and PFV (posterior fossa volume,PFV). Then calculated PV/PFV ratio, CV/PFV ratio and PV/ CV ratio in OPCA group and control group.</p><p><b>RESULTS</b>Compared with control group, in OPCA group wave IIII PL, I - III IPL were significantly elongated (P < 0.05), III - V IPL was significantly shorten (P < 0.05), PV/PFV ratio was significantly decreased (P < 0.01); there was a positive correlation between III-V IPL and PV/PFV ratio (r = 0.83, P < 0.01).</p><p><b>CONCLUSION</b>In patients with OPCA, III PL, I - III IPL of BAEP were elongated and III - V IPL of BAEP was shorten. III - V IPL became shorter when the volume of pontine decreased.</p>
