摘要
目的量化双侧耳硬化患者在两次镫骨切除术期间未手术耳内耳硬化的进展情况,有助于确定术前已接受HRCT扫描的患者是否应在第二次手术前再次进行HRCT扫描。方法回顾性分析35例行双侧镫骨切开术的患者。在第一次手术和第二次手术时对初次手术中未手术的耳部进行两轮HRCT检查和听力学检查。分析HRCT密度测量和听力测量随时间变化的关系。结果第二轮HRCT除内耳前区HRCT密度测量值有微小变化外,在影像学诊断和HRCT密度值上均未增加耳硬化病变变化的显著信息(P = 0.01)。虽然HRCT表现变化较小,但窗前裂(FAF)附近的变化仍与患者的气骨间隙(ABG)呈正相关(p = 0.031, r = 0.388)。结论耳硬化病变进展缓慢,HRCT表现变化不大。因此,对于术后2年内曾做过HRCT评估的患者,术前重复HRCT评估是不必要的。FAF附近HRCT表现的微小变化仍然与ABG的负面影响相关,这可能导致听力阈值在此时间段内恶化。
Stability of computed tomography densitometry in patients with otosclerosis:a two-year follow-up
Objectives
To quantify the progression of otosclerosis in the unoperated ear between two stapedotomy procedures for patients with bilateral otosclerosis which can help to determine whether a HRCT scan should be re-performed before the second surgery for patients who already received HRCT imaging before the initial surgery.
Methods
35 patients who underwent bilateral stapedotomy were included. Two rounds of HRCT examination and audiometry were performed at the time of the first surgery and second surgery on the ear that was not operated on during the initial surgery. The relationship between the changes in HRCT densitometry and audiometry over time was analyzed.
Results
The second round of HRCT did not add significant information about the changes to the otosclerosis lesions in either the imaging diagnosis or the HRCT density values except for small changes in the HRCT densitometry readings at the area anterior to the inner auditory (P = 0.01). While the changes in HRCT manifestation are small, changes near the fissula ante fenestram (FAF) were still positively correlated with the air bone gap (ABG) of patients (p = 0.031, r = 0.388).
Conclusions
The progression of lesions in otosclerosis is slow resulting in small and insignificant changes to the HRCT features. Therefore, a repeat HRCT evaluations prior to surgery is not necessary for patients who have had a previous HRCT evaluation within 2 years of the operation. The small changes in HRCT manifestation near the FAF were still correlated with negative effects on the ABG which could cause worsened hearing thresholds over this timeframe.
期刊介绍:
Journal of Otology is an open access, peer-reviewed journal that publishes research findings from disciplines related to both clinical and basic science aspects of auditory and vestibular system and diseases of the ear. This journal welcomes submissions describing original experimental research that may improve our understanding of the mechanisms underlying problems of basic or clinical significance and treatment of patients with disorders of the auditory and vestibular systems. In addition to original papers the journal also offers invited review articles on current topics written by leading experts in the field. The journal is of primary importance for all scientists and practitioners interested in audiology, otology and neurotology, auditory neurosciences and related disciplines. Journal of Otology welcomes contributions from scholars in all countries and regions across the world.
