目的探讨主观性良性阵发性位置性眩晕临床表现和治疗。方法回顾性分析2003年1月至2006年9月诊治的12例主观性良性阵发性位置性眩晕患者的临床表现和治疗结果,与24例客观性后半规管良性阵发性位置性眩晕比较。结果主观性良性阵发性位置性眩晕临床表现为由头位改变诱发的短暂眩晕发作,而 Dix-Hallpike 诱发试验未见相应的眼震,主观性良性阵发性位置性眩晕发作的潜伏期(±s,下同)为(4.42±2.02)s,持续时间(±s,下同)为(8.67±4.31)s,而客观性后半规管良性阵发性位置性眩晕组分别为(3.20±1.18)s 和(14.75±4.97)s,差异均有统计学意义(t=2.30,P<0.05;t=3.61,P<0.01)。主观性良性阵发性位置性眩晕组首次治疗成功率为91.7%(11/12),客观性后半规管良性阵发性位置性眩晕首次治疗成功率为79.2%(19/24),两者差异无统计学意义;所需的颗粒复位手法次数主观性良性阵发性位置性眩晕组为(1.75±1.08)次(±s,下同),客观性后半规管良性阵发性位置性眩晕组为(3.38±1.06)次,差异具有统计学意义(t=4.32,P<0.01)。随访5～29个月,主观性良性阵发性位置性眩晕组2例复发,客观性后半规管良性阵发性位置性眩晕组7例复发,两者差异无统计学意义。结论主观性良性阵发性位置性眩晕与客观性后半规管良性阵发性位置性眩晕相比,前者眩晕发作潜伏期长、持续时间短,治疗所需的循环数更少,前者治疗结果优于后者。
Objective To investigate the clinical manifestations and treatment of subjective benign paroxysmal positional vertigo. Methods The clinical manifestations and treatment outcome of 12 patients with subjective benign paroxysmal positional vertigo diagnosed and treated from January 2003 to September 2006 were retrospectively analyzed, which were compared with 24 cases of objecive posterior semicircular canal benign paroxysmal positional vertigo. Results The clinical manifestations of subjective benign paroxysmal positional vertigo were transient episodes of vertigo induced by changes of head position, whereas no corresponding nystagmus was found in the Dix-Hallpike induction test. The latency of subjective benign paroxysmal positional vertigo (± s , The same below) was (4.42 ± 2.02) s, and the duration (± s, the same below) was (8.67 ± 4.31) s, while the objectivity of benign paroxysmal positional vertigo was (3.20 ± 1.18) s And (14.75 ± 4.97) s, the differences were statistically significant (t = 2.30, P <0.05; t = 3.61, P <0.01). Subjective benign paroxysmal positional vertigo group first treatment success rate was 91.7% (11/12), objectivity of benign paroxysmal paroxysmal positional vertigo the first treatment success rate was 79.2% (19/24), the difference between the two No statistical significance; the number of particle reduction procedures required for subjective benign paroxysmal positional vertigo was (1.75 ± 1.08) times (± s, the same below), objectivity of the posterior semicircular canal benign paroxysmal positional vertigo group was (3.38 ± 1.06) times, the difference was statistically significant (t = 4.32, P <0.01). During the follow-up of 5 to 29 months, 2 cases relapsed in the subjective benign paroxysmal positional vertigo group and 7 cases in the objective semi-regulatory benign paroxysmal positional vertigo group. There was no significant difference between the two groups. Conclusion Subjective benign paroxysmal positional vertigo compared with objectival posterior semicircular canal benign paroxysmal positional vertigo, the former has a long incubation period, short duration, fewer cycles of treatment, the former treatment is better than the latter By.
