Whether the presence of different degree LF caused by middle ear cholesteatoma aggravates neurosensory hearing loss （NSHL） and what is the degree of the hearing loss caused by LF were still under controversial. This study aimed to investigate whether the LF degree is correlative with the age distribution, disease duration and hearing loss degree for cholesteatomatous patients. Methods The files of 143 patients with middle ear cholesteatoma were selected and reviewed in a retrospective study. Seventy-eight patients with LF were divided into three types according to the degree of destruction of labyrinth. Sixty-five patients without LF were randomly chosen for control. Then, we compared the clinical characteristics of patients with or without labyrinthine fistulae caused by middle ear cholesteatoma. Results According to the study, cholesteatomatous patients with LF were older and suffered longer disease duration than those without LF. Hearing loss is severe with high frequencies both in patients with and without LF. Moreover, inner ear impairment is correlative with the degree of destruction in labyrinth, and more severe destruction in labyrinth follow the more severe symptoms correlative with inner ear impairment. Conclusion Surgical intervention should be performed as early as possible for these cholesteatomatous patients.展开更多

Methods: Enrolled in the study were 60 patients with peripheral vestibular dysfunction caused by a cerebral hypertensive crisis, docu-mented by vestibulometry. Thirty patients underwent standard treatment plus caloric vestibular stimulation, and 30 control group patients received standard treatment alone. Results: After the two-week treatment course, the sensation of vertigo was observed in 40.0% ± 8.9% of treatment group patients compared with 80.0% ± 7.3% of control group patients (t = 3.46;p < 0.001). Spontaneous vestibular somatic reactions were found in 46.7% ± 9.1% of the study treatment group in contrast to 86.7% ± 6.2% of the control group (t = 3.63;p < 0.001). Spontaneous nystagmus was seen in 40.0% ± 8.9% of treatment group patients compared with 93.3% ± 4.6% of control subjects (t = 5.31;p < 0.001). Spontaneous vestibular vegetative reactions were observed in 33.3% ± 8.6% of patients receiving study treatment in contrast to 93.3% ± 4.6% of control group patients (t = 6.16;p < 0.001). Also, 53.3% ± 9.1% of study treatment group patients showed asymmetry of labyrinths compared with 86.7% ± 6.2% of patients from the control group (t = 3.03;p < 0.001). Conclusion: Caloric vestibular stimulation was shown to be an effective treatment for peripheral vestibular dysfunction in patients with cerebral hypertensive crisis. During the 14-day treatment of cerebral hypertensive crisis, complete labyrinthine function recovery occurred in 46.7% of treatment group patients who underwent caloric vestibular stimulation as opposed to 13.3% of control group patients who received standard treatment alone.展开更多
