结论：耳鼻喉科门诊水平管型良性阵发性位置性眩晕（H-BPPV）患者30 s内持续性向地性位置性眼震（PGPN）与一过性向地性位置性眼震（TGPN）的观察足以鉴别。目的：作为一种有效治疗H-BPPV的管石复位术，PGPN与TGPN的鉴别是必要的。本研究的目的是确定足够的观察期，以区分TGPN从PGPN。方法：本研究首先分析了位置性眼震图像记录与红外CCD相机三维在47例H-BPPV。通过分析位置性眼震的时间常数，可准确区分H-BPPV患者的PGPN和TGPN。所有47例患者均拍摄了10秒和30秒的位置性眼震电影。结果：观察30 s后，鉴别TGPN和PGPN的敏感性和特异性分别为100%和97%，观察10 s后，鉴别TGPN和PGPN的敏感性和特异性分别为100%和40%。
Conclusion:A 30 s observation of geotropic positional nystagmus is sufficient to distinguish persistent geotropic positional nystagmus (PGPN) from transient geotropic positional nystagmus (TGPN) in patients with horizontal canal type of benign paroxysmal positional vertigo (H-BPPV) in ENT office.Objective:As a canalith repositioning procedure effectively treats H-BPPV with TGPN, but not PGPN, the differentiation between patients with PGPN and with TGPN is essential. The purpose of this study is to determine the observation period enough to distinguish TGPN from PGPN.Methods:This study first analyzed positional nystagmus images recorded with an infrared CCD camera three-dimensionally in 47 patients with H-BPPV. PGPN is distinguished from TGPN in patients with H-BPPV precisely by means of time constant calculated form analysis of positional nystagmus. Ten-second and 30-s movies were made of positional nystagmus of the all 47 patients. Ten independent otolaryngologists were then asked to distinguish TGPN from PGPN after a 10 s or 30 s observation of the geotropic positional nystagmus images in 47 patients with H-BPPV.Results:The sensitivity and specificity to distinguish TGPN from PGPN was 100% and 97% after 30 s observation, but 100% and 40% after 10 s observation, respectively.
