This study aimed to determine the effect of a structured lecture and discussion on the tinnitus handicap and tinnitus intensity experienced by a group of patients who had undergone surgical removal of a unilateral vestibular schwannoma.
The study design was a prospective repeated measures trial.
The study was conducted on a support group for patients with vestibular schwannoma based on a University Hospital Department of Neuro-Otology.
Twenty-one members of a vestibular schwannoma support group who attended a meeting entitled, "Living with Tinnitus" participated. All patients had undergone a surgical removal of a unilateral sporadic vestibular schwannoma.
A structured lecture and a discussion on the nature of tinnitus and how to live with it by an audiological scientist was performed.
Score on the tinnitus handicap inventory (THI) and associated functional, emotional, and catastrophic subscales and a visual analog scale (VAS) rating of tinnitus intensity were measured. Both measures were taken before intervention and 6 months after intervention. All measures were self-administered.
Of 21 patients attending the lecture, 19 completed both preintervention and postintervention measures. Mean age was 58 years (range, 35-74 years). No significant difference was seen between pre-THI and post-THI total score, subscale scores, or VAS score. No correlation between THI score, VAS score, age, and length of postoperative period was seen. Although preintervention THI and VAS scores were not significantly correlated, there was a significant correlation between THI total and VAS score after intervention and THI functional subscale and VAS score after intervention. The study group was compared with the validation group for THI: significant differences were seen between sample postintervention emotional score and validation emotional score and between sample catastrophic scores and validation catastrophic score. In each case, the sample scores were lower (less handicap) than the validation scores.
This intervention did not make a significant difference to the THI score of the sample group. The fact that the sample group had significantly different tinnitus handicap than the validation group is of note and indicative that postoperative tinnitus in patients with vestibular schwannoma does not lead to as great an emotional and catastrophic handicap as in a general tinnitus group.
本研究旨在确定一场结构化讲座及讨论对一组接受单侧前庭神经鞘瘤手术切除的患者所经历的耳鸣障碍及耳鸣强度的影响。
研究设计为前瞻性重复测量试验。
该研究在一家大学医院神经耳科学科的基础上，针对前庭神经鞘瘤患者的一个支持小组开展。
21名参加了一场名为“与耳鸣共处”会议的前庭神经鞘瘤支持小组成员参与其中。所有患者均接受了单侧散发性前庭神经鞘瘤的手术切除。
由一名听力学专家进行了一场关于耳鸣本质及如何与之共处的结构化讲座及讨论。
测量耳鸣障碍量表（THI）得分及相关的功能、情感和灾难性分量表得分，以及耳鸣强度的视觉模拟量表（VAS）评分。这两项测量均在干预前及干预后6个月进行。所有测量均为患者自行完成。
参加讲座的21名患者中，19名完成了干预前及干预后的测量。平均年龄为58岁（范围35 - 74岁）。干预前和干预后的THI总分、分量表得分或VAS得分之间未见显著差异。THI得分、VAS得分、年龄及术后时间长度之间未见相关性。尽管干预前THI和VAS得分无显著相关性，但干预后THI总分与VAS得分之间以及干预后THI功能分量表与VAS得分之间存在显著相关性。将研究组与THI的验证组进行比较：样本干预后情感得分与验证情感得分之间以及样本灾难性得分与验证灾难性得分之间存在显著差异。在每种情况下，样本得分均低于（障碍更小）验证得分。
该干预措施对样本组的THI得分未产生显著差异。样本组与验证组的耳鸣障碍存在显著差异这一事实值得关注，表明前庭神经鞘瘤患者术后耳鸣所导致的情感和灾难性障碍不如一般耳鸣组严重。
