Laryngocele is a rare clinical condition characterized by an abnormal dilation of the laryngeal saccule. The present study focused on two separate cases of diagnosed patients. The first patient suffered from internal laryngocele and complained of hoarseness for almost 1 year. Plasma was used to treat the internal laryngocele and the outcomes were satisfying. The patient did not undergo any tracheostomy due to previous endoscopic surgery. The second patient included in the present study was diagnosed with mixed laryngocele and complained of swelling on the left side of the upper aspect of the neck with considerable pain for >1 month. The patient was prepped for excision by an external transcervical technique under general anesthesia. None of the two patients had any recurrence or other changes during follow-up. The purpose of reporting these two cases of laryngocele was to increase awareness of this condition. Surgery is still the first-line treatment for diagnosed cases, but with the advent of new microscopic techniques, the use of plasma in an inter-pharynx setting has become more common. The results observed after using plasma to treat one internal laryngocele may be relevant to better understanding the application of this method and confirm that it may be a new suitable approach to treat this condition.

本文报道1例发生于老年男性内含囊液的喉外型喉气囊肿。患者男，63岁，因“右颌下肿物渐进性增大10年余”就诊。术前磁共振（MRI）提示右颌下腺下方类圆形异常信号影，内可见气液平面。在全身麻醉下行颈外入路肿物完整切除手术。大体检查示，囊肿呈微黄色，囊壁为致密结缔组织包膜，术后病理诊断为喉气液囊肿。术后3 d出院，出院至今复查未见肿物复发，预后良好。.

Objective: To summarize clinical features and our experience of the diagnosis and treatment of laryngocele. Methods: Clinical data of 11 laryngocele patients in department of Otorhinolaryngology Head and Neck Surgery of the Second Affiliated Hospital of Shanxi Medical University from January 2012 to December 2021 were retrospectively reviewed, including 9 men and 2 women, aged from 12 to 75 years, with median age of 56 years. Electronic laryngoscope was performed in 10 of all patients, laryngeal CT in 10 and cervical color ultrasound in 5 before operation.All the operations were performed under general anesthesia, and the external cervical approach was used for external and combined laryngocele. The internal laryngocele was resected by low temperature plasma through transoral endoscopy. Patients were followed up regularly after operation to evaluate the effect. Clinical feature, types of lesions, imaging findings, surgical approaches and follow-up results were analyzed through descriptive statistical method. Results: Eleven laryngocele patients were divided into mixed type (n=6), internal type (n=4) and external type (n=1).Nine patients presented with hoarseness or dysphonia, 7 with cervical mass and 1 with airway obstruction. Surgical resections were done through external cervical approach (n=7)or transoral endoscopic approach (n=4). All the operations were successful and no complication occurred. All cases were followed up from 17 to 110 months. No recurrence was encountered. Conclusions: Laryngocele is a rare lesion with atypical clinical presentation. Preoperative imaging including CT scan and electronic laryngoscope is essential to evaluate the location, and extent of the lesion, and to make the surgical plan.Complete surgical excision is required. Surgical resection is the only effective method for the treatment of laryngocele.
目的： 总结喉气囊肿的临床特点及诊疗经验。 方法： 回顾性分析2012年1月至2021年12月山西医科大学第二医院耳鼻咽喉头颈外科收治的11例喉气囊肿患者的临床资料，其中男9例，女2例，年龄12~75岁，中位年龄56岁。患者术前行电子喉镜（10例）、喉CT（10例）和颈部彩色超声（5例）检查。手术均在全身麻醉下进行：喉外型和混合型病变采取颈外入路；喉内型病变采取经口内镜下低温等离子切除。采用描述性统计学方法分析其主要临床表现、病变类型、影像学结果、手术入路、并发症及随访结果。 结果： 11例喉气囊肿患者病变类型分为混合型（6例）、喉内型（4例）及喉外型（1例）。主要临床表现为声嘶或发声不清者9例，颈部肿块者7例，气道阻塞者1例。手术入路包括颈外入路（7例）和经口内镜入路（4例），全部患者手术顺利，术中无并发症出现。术后随访17~110个月，全部病变无复发。 结论： 喉气囊肿临床罕见，临床表现缺乏特异性。术前CT及电子喉镜检查有助于评估病变的部位、范围，并指导手术治疗。手术切除是治疗喉气囊肿唯一有效的方法。.

本文报道2例发生于中年男性的单侧喉内型喉气囊肿。例1患者，53岁，因“咽部不适3年，声嘶半个月”入院。例2患者，58岁，因“咽部异物感2年，加重2个月”入院。2例患者术前影像学检查均提示喉部肿物内含气体。入院后全身麻醉下经口硬质支撑弯喉镜辅助的内镜手术（curved laryngoscope assistant transoral surgery，CLATOS，即下咽镜技术）完整切除肿物。术后病理回报均为喉部囊肿，术后随访至今未见肿物复发。.
