Objective  To investigate the effect of preoperative anxiety, depression and sleep quality on sequelae of Bell's palsy and its intervention strategy.

  Methods  Forty-eight patients receiving neurolysis of facial nerve of stem hole area were divided into good prognosis group (n=40) and poor prognosis group (n=8) according to Sunnybrook facial nerve evaluation score after 6 months. Preoperative 1 day Sunnybrook facial nerve evaluation form, Self-rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS) and Pittsburgh Sleep Quality Index (PSQI) scores were observed. The SAS, SDS and PSQI scores were compared between the two groups. The impacts of preoperative anxiety level, depression degree and sleep quality on the operative effect were observed.

  Results  The SAS, SDS and PSQI scores in the good prognosis group were significantly lower than those in the poor prognosis group (P < 0.05). There were significant correlations between operative efficacy and preoperative anxiety level, degree of depression as well as sleep quality (P < 0.05).

  Conclusion  The preoperative anxiety and depression degree as well as sleep quality of patients with sequelae of Bell's palsy significantly affect the therapeutic effect of neurolysis of facial nerve of stem hole area, and preoperative intervention can be taken for patients.
