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.

Laryngoceles are best treated with surgery. The goal of this study is to compare patient outcomes and complications in patients undergoing removal of laryngoceles with either transoral endoscopic/microlaryngoscopic or robotic approaches. A systematic review of the published literature was conducted using Pubmed, Web of Science, and the Cochrane Clinical Trials databases. A pooled analysis of individual data was used to compare outcomes between robotic and endoscopic approaches. A total of 30 studies were included. Nine studies with 95 patients were included in the final analysis. Eighty-one (85.26%) were treated with microlaryngoscopic surgery and 14 (14.74%) were treated with robotic-assisted surgery. The rates of tracheostomy (RR = 1.44, 95% CI = 0.389-5.332), complications (RR = 0.329, 95% CI = 0.047-2.294) and recurrence (RR = 0.354, 95% CI = 0.021-5.897) were not statistically different between groups. Within the endoscopic subgroup, 66 laryngoceles (78.57%) were completely excised, while 18 (21.43%) laryngoceles were treated with marsupialization. Marsupialization was associated with an increased risk of recurrence (RR = 4.889, 95% CI = 1.202-19.891). In the robotic subgroup, there was an increased risk of nasogastric tube use (RR = 103.867, 95% CI = 6.379-1619.214) and a longer mean length of hospital stay (p = 0.0001). Transoral treatment of laryngoceles has complication and recurrence rates of 18.95% and 7.37%, respectively. Robotic approaches are associated with higher rates of NGT use and increased hospital stay, however much of this is due to one robotic surgeon\'s preference for routine NGT placement and higher rates of combined laryngocele removal via robotic approach. Complete excision of combined laryngoceles is possible with transoral approaches. Marsupialization, reported in traditional endoscopic approaches, is associated with a significantly higher rate of recurrence (22.22% vs. 4.76%).

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.

OBJECTIVE: A laryngocele is a space that develops as a result of pathological dilatation of the laryngeal saccule. However, the reported management of laryngoceles varies. We conducted a systematic review of the literature regarding the surgical management of laryngoceles and pyolaryngoceles, to understand the evolving nature of treatment for this rare condition.
METHODS: We searched for publications in the PubMed, Cochrane Library, JBI Library of Systematic Reviews, and Ovid databases using the terms \"laryngocele\", \"pyolaryngocele\", and \"laryngopyocele\", and reviewed the identified articles.
RESULTS: After removal of repeated studies and filtering for relevance and studies written in English, a total of 227 studies were included in this review. No meta-analyses or randomized controlled trials have been published. The identified studies have been summarized in 14 reviews conducted since 1946. The meta-analysis determined that endoscopy was the preferred approach for internal laryngoceles, while combined laryngoceles benefited from both internal and external surgical approaches.
CONCLUSIONS: Laryngocele management has progressed since its initial description, from open surgery to an endoscopic approach, and more recently to a robotic-assisted surgical approach. The uptake of robotic surgery as a possible treatment modality over the last decade shows much promise for the treatment of these conditions.

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.

A systematic review on laryngopyoceles across Ovid, PubMed, and Google Scholar database was conducted. A total of 61 papers published between 1952 and 2015 were found. Of these, 23 cases written in English, which described the number of cases, surgical approaches, resort to tracheostomy, complications, and outcomes, were shortlisted. Four cases of laryngopyoceles were managed endoscopically using a cold instrument, microdebrider, or laser. Eighteen cases were operated via an external approach, and 1 case applied both approaches. One of 4 endoscopic and 10 of 18 external approaches involved tracheostomy. The present study aimed to report a case of large mixed laryngopyocele that was successfully drained and marsupialized endoscopically using suction diathermy without requiring tracheostomy. Management using suction diathermy for excision and marsupialization of a laryngopyocele has never been reported and can be recommended as a feasible method due to its widespread availability. In the presence of a large laryngopyocele impeding the airway, tracheostomy may be averted in a controlled setting.
UNASSIGNED: None specified.

This is case report of 35-year old male patient presented with hoarseness and swelling on left side of neck. The swelling was noticed by the patient for 8 months. It has been diagnosed clinically and radiologically as a combined laryngocele. The laryngocele has been successfully excised using and combined approach i.e., external and endoscopic methods. This case has been reported for its rarity at this age.

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.
