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.

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.

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.

The laryngocele is an abnormal cystic dilatation of the saccule or appendix of the laryngeal ventricle, filled with air and communicating with the lumen of the larynx. When the neck of the laryngocele is obstructed, it becomes filled with mucus of the glandular secretion and is changed to a laryngomucocele. When this lesion becomes infected, a laryngopyocele is formed. The laryngocele is fairly rare and laryngopyocele occurs even more rarely. Overall, 39 cases of laryngopyocele have been reported in the world literature. Only in 4 cases was a laryngopyocele reported to have caused acute airway obstruction and only one case of internal laryngopyocele causing acute airway obstruction has been reported until now. This is the first case reported in the literature of an internal laryngopyocele in a female patient in a septic condition, which caused almost 100% obstruction of the airway. An emergency tracheotomy was performed in order to secure the airway. Computed tomography of neck was performed which revealed a cystic 29 mm hypodense mass extending from the right false vocal cord to the level of the epiglottis, narrowing the laryngeal cavity and causing an almost 100% airway obstruction. Laryngopyoceles may present with a rapid and alarming obstruction of the airway and, therefore, an urgent tracheotomy may be inevitable. It is an emergency case, in the field of otolaryngology, and should be included in the differential diagnosis of acute airway obstruction, especially when hoarseness, stridor and fever are present. Diagnosis requires a high index of suspicion for these lesions and scrupulous clinical and radiological evaluation. A computed tomography scan is critical in determining the nature and site of the lesion. The recommended treatment of laryngopyocele is immediate endoscopic drainage. Definitive management of laryngopyoceles is surgical excision which can be performed immediately after endoscopic drainage or some time thereafter.
