Case report and literature review Palabras clave: Anterior cysts are characterized by a submucosal mass dependent on the false vocal cord that protrudes through the anterior portion of the ventricle, while lateral cysts, usually the most common, occupy the entire ventricular band and exit the pharynx through the mucosa of the aryepiglottic fold The first is caused by obstruction or atresia of the sac, which, depending on its location, will make the cyst more extensive or not.

Lateral saccular cysts of the larynx. Contrast coronal CT scan of the neck showing a cystic lesion extending from the piriform sinus to the trachea with a significant decrease in the caliber of the airway. Ann Otol Rhinol Laryngol ; Another endoscopic approach that has shown lower morbidity is CO2 laser vestibulectomy, since it reduces surgical time, avoids vascular or superior laryngeal nerve damage and accelerates tissue recovery.

Ear Nose Throat J. Dias II ; Emanuel C. The second may be a consequence of sac obstruction secondary to neoplasia, trauma or inflammation with subsequent fibrosis Management of subglottic stenosis in infancy and childhood. Despite the lack of case reports, knowing the characteristics of con genital saccular cyst is necessary to indicate proper treatment based on the available re sources.

Flexible laryngoscopy in neonates, infants, and young children. Do cuffed endotracheal tubes increase the risk of airway mucosal injury and post-extubation stridor in children?

Congenital laryngeal saccular cyst

A right cystic-appearing lesion 1. Contencin P, Narcy P.

The definitive management, as stated in the literature, is microlaryngoscopy, since most reports and case series use CO 2 laser for endoscopic resection 3,19, The sac is a diverticular structure that lies between the ventricular bands and the vocal cords, projects vertically upward between the base of the epiglottis and the medial portion of the thyroid cartilage, and contains a stratified and cylindrical pseudostratified squamous epithelium with large numbers of mucous glands, which are believed to be used for the lubrication of the vocal cords 10,4.


The main symptom of this pathology is stridor at birth that can conceal laryngomalacia or congenital vocal cord paralysis, which appear with stridor in the first weeks of life Diagnosis is achieved by laryngeal endoscopy, images or clinical review.

How to cite this article. Other symptoms depend on the size of the lesion and its location; for example, dysphagia may occur if the cyst occupies the hypopharynx 12 or if there is progressive respiratory distress until total airway obstruction, cyanosis, apnea, hoarse cry and low-pitched cry, especially with changes of position or agitation.

It was possible to resect a laryngeal saccular cyst smaller than 3cm in a safe and effective manner through microlaryngoscopy and radiofrequency, despite the lack of case reports regarding the use of this method. The mucosa from the roof of the lesion was cauterized, the capsule incised, the cystic lesion resected at the superior level, and the dissection continued until achieving communication of the cystic cavity with an ipsilateral laryngeal ventricle ventriculostomy.

Own elaboration based on the data obtained in the study. The search for the second lesion. Contrast computed tomography CT of the larynx with 3D reconstruction under sedation was requested to assess the extension of the lesion.

Evaluation of the child in respiratory distress. A series of six cases.

To review the literature and report a case of congenital laryngeal saccular cyst, as well as its treatment by endoscopic approach and radiofrequency, which is most easily found in our country. Respiratory distress was observed, which required supplementary oxygen as first measure, llaringeo moving to non-invasive mechanical ventilation without improvement, and ending with orotracheal intubation.

T habet MH, Kotob H. Despite the low frequency of this pathology, it is important to know and be able to diagnose and treat it safely and effectively with the resources available in most hospitals in Colombia. Flexible carbon dioxide laser-assisted endoscopic marsupialization and ablation of a laryngeal saccular lringeo in a neonate.

Airway obstruction in a newborn due to a congenital laryngeal cyst. Stridor in the neonate and infant. Understanding this disease is high ly important to achieve proper diagnosis and provide treatment using the resources avail able in our country, such as radiofre quency.

Arch Dis Childhood ; Prospective description of patients with congenital and acquired stridor in early infancy. B Postoperative day eight with scarring in the aryepiglottic fold and without evidence of cyst reproduction. The saccular cyst consists of a dilation of the laryngeal ventricle filled with mucus that does not communicate with the laryngeal lumen 9.

Radiofrequency ablation of laryngeal saccular cyst in infants: Considering the circumstances, a checkup with microlaryngoscopy was performed 8 days after surgery, and adequate healing of the lesion and non-reproduction of cyst, glottis and free subglottis were observed Figure 3.

Respiratory manifestations of gastroesophageal reflux disease in pediatric patients. One of its causes, although rare, is congenital laryngeal saccular cyst 1 ; however, differential diagnoses include more frequent pathologies such as laryngomalacia, tracheomalacia, subglottic stenosis, vocal cord paralysis, laryngocele, laryngeal membrane, among others 2. Int J Pediatr Otorhinolaryngol.

This obstruction can be caused by the abnormal migration of the tissue from the fourth branchial arch generating the cystic formation 14 or by the isolation of the cells of the sac due to the abnormal migration of mesenchymal cells through persistent fetal vessels in the larynx.
