目的:评估中耳手术后的味觉障碍,它们的改变因素,尤其是鼓索神经损伤或潜在的耳科疾病。我们调查了味觉障碍对生活质量的影响。
方法:前瞻性队列研究。
方法:三级护理中心的单中心研究。
方法:共214例接受中耳手术的患者。在1年的随访期内通过问卷调查收集有关味觉障碍的数据。
结果:在第10天报告了42.7%的味觉障碍,在4个月的23.3%中,术后1年为9.2%。当鼓索神经最初健康时,在整个随访期间,味觉障碍在横切后更为常见。当它参与胆脂瘤或炎症过程时,神经伸展后,术后味觉障碍更常见。在Likert量表上,日常生活中的术后不适评分为10分之3.5分。25.8%的患者报告了饮食调整,和15%的患者的情绪改变。
结论:味觉障碍在中耳手术后常见,尽管它们在最初的几个月中大多改善。当CTN健康时,切割它比拉伸它会导致更多的味觉障碍,因此主张其保存以防止这些症状。然而,在病理性CTN的情况下,切断这条神经,这有时是控制疾病所必需的,比伸展它更不容易引起味觉障碍。这些味觉障碍是不适的根源,可能存在饮食改变和情绪影响的风险。
OBJECTIVE: To evaluate taste disorders after middle ear surgery, their modifying factors especially chorda tympani nerve injury or underlying otologic disease. We investigated consequences of taste disorders on quality of life.
METHODS: Prospective cohort study.
METHODS: Monocentric study in tertiary care center.
METHODS: A total of 214 patients who underwent middle ear surgery were included. Data regarding taste disorders were collected by questionnaires over a 1-year follow-up period.
RESULTS: Taste disorders were reported in 42.7% at 10 days, in 23.3% at 4 months, and in 9.2% 1 year postoperatively. When the chorda tympani nerve was initially healthy, taste disorders were more frequent after its transection throughout the follow-up period. When it was involved in a cholesteatoma or inflammatory process, postoperative taste disorders were more frequent after nerve stretching. Postoperative discomfort in daily life was rated on the Likert scale at 3.5 out of 10. Dietary modifications were reported by 25.8% of patients, and mood alterations by 15% of patients.
CONCLUSIONS: Taste disorders are frequent after middle ear surgery although they mostly improve in the first months. When the CTN is healthy, cutting it leads to more taste disorders than stretching it, thus advocating its preservation to prevent these symptoms. However, in cases of pathological CTN, cutting this nerve, which is sometimes necessary to control the disease, is less likely to cause taste disorders than stretching it. These taste disorders are a source of discomfort and may present risks of dietary modifications and emotional impact.
