Abstract：
Laryngocele, an abnormal dilation of the appendix of the laryngeal ventricle filled with air, is a rare condition predominantly presenting unilaterally. However, bilateral occurrences are exceedingly rare. In this article, we present a case of bilateral laryngocele along with a comprehensive literature review. A 57-year-old male presented with dyspnea, stridor, and bilateral neck masses. His medical history included chronic cough and intermittent hoarseness. Over a 3 month period, the neck masses progressively enlarged, resulting in respiratory distress. Interestingly, he denied experiencing weight loss, decreased appetite, or fever. Clinical examination revealed sizable, soft masses on both sides of the neck, obstructing lymph node assessment. Computed tomography (CT) imaging confirmed the presence of a left combined laryngopyocele and a right combined laryngocele. Subsequently, the patient underwent tracheostomy. Benign biopsy results excluded malignancy. Surgical excision of bilateral laryngoceles resulted in an uneventful recovery. The term \"laryngocele\" was introduced by Virchow in 1867 to describe the abnormal dilation of the saccule associated with Morgagni\'s ventricle. Diagnosis involves a thorough patient history, physical examination, and radiological imaging, notably CT, to differentiate laryngoceles from other conditions. Typically asymptomatic, they are often incidentally discovered around age 50, although symptoms such as voice changes or breathing difficulties can manifest. A review of the literature identified 77 documented cases, primarily in males, exhibiting various symptoms and treatment modalities. This case underscores the rarity of bilateral combined laryngocele, emphasizing the importance of timely diagnosis and surgical intervention for favorable outcomes. Comprehensive research reveals diverse clinical aspects, highlighting the necessity for continued investigation to enhance management strategies.
摘要：
喉头膨出,充满空气的喉室阑尾的异常扩张，是一种罕见的情况，主要是单方面出现。然而,双边事件极为罕见。在这篇文章中,我们介绍了一例双侧喉膨出的病例，并进行了全面的文献综述。一名57岁男性出现呼吸困难,stridor,和双侧颈部肿块。他的病史包括慢性咳嗽和间歇性声音嘶哑。在三个月的时间里，颈部肿块逐渐扩大，导致呼吸窘迫.有趣的是,他否认经历过减肥,食欲下降,或发烧。临床检查显示相当大，颈部两侧柔软的肿块，阻塞淋巴结评估。计算机断层扫描（CT）成像证实存在左合并喉囊肿和右合并喉囊肿。随后，患者接受了气管造口术。良性活检结果排除恶性肿瘤。双侧喉癌的手术切除导致了顺利的恢复。“喉癌”一词由Virchow于1867年引入，用于描述与Morgagni心室相关的囊的异常扩张。诊断涉及全面的病史，体检,和放射成像，尤其是CT,将喉癌与其他疾病区分开来。通常无症状，它们通常在50岁左右偶然发现，尽管声音变化或呼吸困难等症状可能会出现。对文献的审查确定了77起记录在案的案件，主要是男性，表现出各种症状和治疗方式。该病例强调了双侧合并喉膨出的罕见性，强调及时诊断和手术干预以获得良好结果的重要性。综合研究揭示了不同的临床方面，强调继续调查以加强管理策略的必要性。
