Laryngeal air cyst (laryngocele) is a rare disease that is an abnormal cystic expansion of the deep structures of the laryngeal ventricle. They can be accompanied by serious complaints, such as shortness of breath, difficulty breathing during exercise, as well as at rest with large cysts. Computed tomography is the most effective method for determining the type, localization and degree of laryngocele. Although surgical treatment is considered the method of choice in cases of laryngeal air cyst, the approach significantly depends on the size of the lesion.
Воздушная киста гортани (ларингоцеле) — редкое заболевание, представляющее собой аномальное кистозное расширение глубоких структур гортанного желудочка. Симптоматика ларингоцеле вариабельна: от незначительных жалоб на дискомфорт при глотании и фонации, затруднение дыхания вплоть до одышки при физической нагрузке и/или в покое. В дополнение к визуализации гортани при эндоскопическом осмотре может быть использована компьютерная томография, которая является эффективным методом определения типа, локализации и степени ларингоцеле. Оперативное лечение — основной метод лечения данной патологии; способ хирургического подхода зависит от размера и локализации патологического процесса.

UNASSIGNED: Pyolaryngocele is a very rare and serious complication of laryngocoele. The clinical presentation can be extremely severe acute epiglottitis with laryngeal dyspnea and major dysphagia. The treatment of choice is surgical excision. Our aim is to attract the intention of the surgeon to this unusual entity and describe its clinical features.
METHODS: We report a case of a 70-year-old male patient with a five-day history of left neck swelling, sore throat, and low-grade fever. An urgent CT scan showed a mixed pyolaryngocele. The management consisted of high-dose antibiotics and excision of the residual laryngocoele via an external approach.
UNASSIGNED: A pyolaryngocele is an unusual complication of laryngocoele that becomes secondarily infected causing serious symptoms. The management consists of administrating broad-spectrum antibiotics and aspiration of purulent material to decompress the sac. At a later stage, after relieving the acute symptoms we performed an external approach with formal excision of the laryngocele.
CONCLUSIONS: Pyolaryngocele is a rare complication of laryngocele and can present with serious complaints like dyspnea and sepsis. Excision of the laryngocoele is still the best treatment option to prevent this complication and recurrence.

Laryngocele is an uncommon benign cystic dilatation of the laryngeal saccule that communicates with the laryngeal lumen and contains air. On the basis of its localization, it can be traditionally classified in internal, external, or mixed. Usually unilateral and rarely bilateral, it may be congenital or acquired. It most often appears later in life without important symptoms except for cervical swelling. Here, together with a review of literature, we report the case of a 72-year-old man, smoker but without other specific risk factors, who presented laryngeal dyspnea for about one year. Neck CT scan performed during a previous hospitalization for respiratory failure revealed a left mixed laryngocele that was later surgically removed with cervicotomic access. The patient was discharged after one week. One month after surgery, we confirmed the absence of disease with video laryngoscopy.

Laryngocele is an abnormal cystic dilatation of the saccule of the larynx. It communicates with the laryngeal lumen and contains air. Laryngocele can be classified as internal (within the larynx), external (outside the larynx) and mixed (both). It is a rare entity. Hereby, we are reporting a case of laryngocele, which presented to us with a diagnostic quandary. After confirming the diagnosis by radiology, patient was operated upon by external approach. In the following article, we also discuss the establishment of the diagnosis and review different surgical modalities for the management of various types of laryngocele.

Laryngocele is a rare benign lesion of the larynx caused by an abnormal dilatation of the laryngeal saccule. We report the case of a 78-year-old man presenting bilateral cervical painless soft mass. Bilateral external laryngocele diagnosis was confirmed by CT scan and the patient underwent a surgical resection.

Laryngopyocele is a rare complication involving the laryngocele which can present with acute airway compromise. A 31-year-old man presented with acute onset respiratory distress and dysphagia. He had swelling on either side of upper aspect of the neck with tenderness on left side. Videolaryngoscopy using 70° rigid Hopkins rod telescope showed a swelling in the left pyriform sinus pushing the ipsilateral vocal cord. However, glottic space was adequate. Contract-enhanced CT scan of the neck confirmed left-sided mixed laryngopyocele with contralateral mixed laryngocele. Patient underwent excision of both the lesions in a single stage by transcervical approach. Laryngopyocele in a case of bilateral mixed laryngocele presenting as an impending airway emergency has not been reported in literature. The diagnostic and therapeutic challenges are discussed here along with review of literature.

Laryngocele is a rare entity and can be defined as an abnormal cystic dilatation of saccule of the laryngeal ventricle with communication to the lumen of larynx. Laryngopyocele is a rare complication of laryngocele when it is infected. Patients may present with fever, neck swelling, shortness of breath, and hoarseness. Acute presentation can develop rapidly with alarming symptom, such as stridor, which signifies airway obstruction and warrants immediate treatment and airway protection. Computed tomography and endoscopy are useful in making the diagnosis and delineate the severity of disease. Laryngopyocele should be treated with antibiotics, drainage of purulent content, and followed by definitive surgical excision.

A 71 years old male with throat discomfort, shortness of breath, irritating cough admission. Fiberoptic laryngoscope: bilateral glottis ventricular zone with about quail egg size smooth cystic masses. Throat enhanced CT: infrahyoid margin level about bilateral aryepiglottic fold inside have package containing gas shadow, communicated with the laryngeal chamber. Support laryngoscope under coblation radiofrequency ablation assisted laryngeal cyst excision were done and postoperative pathology consistent with laryngocele.
