This study aimed to study the correlation and incidence between arytenoid prolapse after open airway surgeries and its risk factors, and to classify the degree of arytenoid prolapse in the adult population.
From 2015 to 2020, we reviewed the charts of adult patients aged > 16 years who had undergone open airway surgeries at our facilities. We excluded patients with pre-existing arytenoid prolapse, limited postoperative endoscopic documentation, or loss to follow-up.
The study included 23 patients; most of whom were 40 years (73.91%) and males (65.57%). Subglottic stenosis (SGS) Grade 3 (47.8%) was the most common grade prior to our intervention. No significant association was observed between the degree of SGS, comorbidity, presence of tracheostomized status, operation type (cricotracheal resection or laryngotracheal reconstruction), and the presence of arytenoid prolapse. Patients with bilateral vocal cord immobility were more likely to have arytenoid prolapse compared to those with normal vocal fold mobility (P = 0.045).
In adults, open airway surgeries did not correlate with arytenoid prolapse unless the patients had an immobile vocal cord. This may be due to the altered position of the arytenoid cartilage in cases of vocal fold immobility. Moreover, paralysis of the posterior cricoarytenoid muscles can lead to arytenoid apices prolapse anteromedially.
本研究旨在探讨气道开放手术后杓状软骨脱垂与其危险因素之间的相关性及发生率，并对成年人群的杓状软骨脱垂程度进行分类。
回顾2015年至2020年期间在我院接受气道开放手术的16岁以上成年患者的病历。排除术前已有杓状软骨脱垂、术后内镜记录有限或失访的患者。
本研究纳入23例患者；其中大多数为40岁（73.91%），男性（65.57%）。干预前声门下狭窄（SGS）3级（47.8%）最为常见。未观察到SGS程度、合并症、气管切开状态、手术类型（环状气管切除术或喉气管重建术）与杓状软骨脱垂之间存在显著关联。与声带活动正常的患者相比，双侧声带固定的患者更易发生杓状软骨脱垂（P = 0.045）。
在成年人中，气道开放手术与杓状软骨脱垂无关，除非患者有声带固定。这可能是由于声带固定时杓状软骨位置改变所致。此外，环杓后肌麻痹可导致杓状软骨尖向前内侧脱垂。
