Tratamiento endoscópico de una hendidura laríngea posterior: reporte de un caso y revisión de la literatura / Endoscopic treatment of a laryngeal cleft: case report and literature review

RESUMEN Las hendiduras laríngeas posteriores son anomalías congénitas de la laringe de baja incidencia que comprometen la región interaritenoidea o la lámina cricoidea. En caso de extenderse hasta la tráquea son denominados clefts laringo-tráqueo-esofágicos. Su clínica es inespecífica y debe sospecharse en todo niño con trastorno de deglución y neumonía aspirativa a repetición. A continuación, presentamos un caso de un cleft laríngeo tipo 2 tratado endoscópicamente.

ABSTRACT The posterior laryngeal clefts are congenital anomalies of the larynx of low incidence that comprise the interaritenoid region or the cricoid lamina. In case of extending to the trachea they are called laryngo-tracheo-esophagic clefts. Its clinic is non-specific and should be suspected in any child with swallowing disorder and aspiration pneumonia. We present a case of an endoscopically treated laryngeal cleft type 2.

Laryngeal clefts: a review of current literature / 中华耳鼻咽喉头颈外科杂志

Laryngeal clefts as exceptionally rare congenital anomalies have been reported more and more recently. The clinical symptoms and presentations base on degree of clefts and variety of comorbidities. Mild types of clefts may have minimal clinical impact, whereas severe types may be life-threatening and even lead to death before diagnosis. With more attention of these anomalies and advances in endoscopy, the diagnosis, evaluation and surgery of laryngeal clefts have acquired great improvement, especially International Pediatric Otolaryngology Group(IPOG)have reported consensus guidelines on the diagnosis and management of type Ⅰ laryngeal clefts in 2017. This review of laryngeal clefts may be beneficial to decrease missed diagnosis or misdiagnosis and to achieve individual-based treatment.

Pediatric laryngeal clefts: an experience in the diagnosis and management of 13 cases / 中华耳鼻咽喉头颈外科杂志

Objective@#To investigate the diagnosis and management of laryngeal cleft.@*Method@#The clinical data of 13 cases of laryngeal cleft treated between 2007 and 2015 was analyzed retrospectively.@*Results@#The children with laryngeal cleft were classified according to the classification of Benjamin-Inglis, as type Ⅰ(11 cases), typeⅡ(1 case) and type Ⅲ(1 case). All patients were confirmed by microlaryngobronchoscopy under general anaesthetic. Eleven typeⅠ and 1 type Ⅱ clefts were managed conservatively, with which all type Ⅰ patients were successfully managed, while the type Ⅱ patient was resolved by surgical endoscopy. The type Ⅲ patient was treated by open repair but the results was poor.@*Conclusions@#Patients who suffered with choking on feeding or recurrent aspiration pneumonia, especially coexisted with other congenital malformation, needed detailed evaluation for laryngeal cleft, although which was a rare congenital abnormality. Electronic laryngoscope could be the first step to screen the cleft, while microlaryngobronchoscopy is the gold standard for diagnosis of laryngeal cleft. The majority of children with lower type clefts can be managed conservatively. Surgical endoscopy has high success rate when strictly following the indication. Type Ⅲ and Ⅳ clefts have high mortality for usually combining with severe complications and abnormalities.

Síndrome aspirativo por hendidura laríngea en un lactante / Aspiration syndrome due to laryngeal cleft in an infant

La aspiración es el pasaje de contenido alimentario y de secreciones endógenas hacia la vía aérea. La causa puede ser anatómica, neuromuscular o funcional. La hendidura laríngea es una anomalía congénita poco frecuente que debe ser considerada en el diagnóstico diferencial de síndrome aspirativo en recién nacidos y lactantes. Los síntomas principales son el estridor, las infecciones respiratorias recurrentes, y las crisis de cianosis, tos y asfxia durante la alimentación. El diagnóstico se confrma mediante el examen endoscópico. La conducta terapéutica dependerá, entre otros factores, de la extensión de la hendidura que se presente. Se describen las manifestaciones clínicas, los métodos diagnósticos y el tratamiento de un lactante con esta patología, y se enfatiza la necesidad de reconocer los trastornos de la deglución en los niños a fn de establecer el diagnóstico preciso y el tratamiento apropiado para prevenir y evitar la desnutrición, así como el compromiso pulmonar grave y potencialmente irreversible.

Aspiration is the passage of food content and endogenous secretions into the airway. Anatomical, neuromuscular or functional anomalies are among the major causes. The laryngeal cleft is a rare congenital anomaly that should be considered in the differential diagnosis of aspiration syndrome in neonates and infants. The main symptoms are stridor, recurrent respiratory infections and cyanotic crisis, cough and choking during feeding. The diagnosis is confrmed by endoscopic examination. The therapeutic behaviour will depend on the extent of the cleft, among other factors. We describe the clinical manifestations, diagnostic methods and treatment of an infant with this disease, and we emphasize the need for recognition of swallowing disorders in children in order to establish an accurate diagnosis and appropriate treatment to prevent and avoid malnutrition as well as a severe and potentially irreversible lung compromise.

A Case of Congenital Short Trachea Combined with Laryngeal Cleft / 소아알레르기및호흡기학회지

Congenital short trachea is a rare congenital anomaly in which the trachea is composed of reduced number of cartilage rings, which result in an abnormally high position of the carina and an abnormal course of the main bronchi. Hazards of congenital short trachea in infants and children include inadvertent bronchial intubation, because it causes bronchiostenosis, pulmonary interstitial emphysema, pneumomediastinum, pneumothorax, and ipsilateral atelectasis. Laryngeal cleft is a rare condition, as well. Symptoms range from mild stridor to massive aspiration and respiratory distress, depending on the severity of the cleft. Until now, a case with combination of these two rare congenital defects has not been reported. Herein, we report a 13 month-old boy who has congenital short trachea with laryngeal cleft.

A Case of CongenitaI LaryngeaI Cleft / 소아알레르기및호흡기학회지

Congenital laryngeal cleft is a rare anomaly, which can cause serious problems of airway and repeated aspiration pneumonia. It is due m failure of fusion of the posterior cricoid cartilage lamina. Dysphagia with aspiration of food is commonly seen w1h resultant bouts of pneumonia. Detection of an unsuspected minor cleft may be difficult, but the pediatrician should suspect the possibility of deft from the clinical features. This paper includes. a detailed case report of one patient with congenital laryngeal cleft and the review of literatures.

A case of laryngeal cleft

Laryngotracheoesophageal cleft is a rare congenital anomaly characterized by a midline defect of variable length between the posterior larynx and trachea and the anterior wall of the esophagus which was first reported by Richter in 1792. The male, birth weight 2780 gm, was born our hospital, After birth the infant breathed spontaneously, cried immediately but weak and did well initially but after minutes appeared moderate amount of mucus in the mouth, and sterile water was given but immediately vomited with chocking, cough and cyanosis. A nasogastric tube was inserted through the esophagus without resistance and kinking. Esophagogram was showed spillage of contrast media simultaneously into trachea and esophagus. In direct laryngoscopy, there appeared to be small laryngeal cleft posteriorly, to the level of vocal cord. But bronchoscopy could not be performed due to narrow tracheal orifice. So we confirmed the laryngeal cleft by means of CT and MRI of neck. CT and MRI scan of neck demonstrated a cleft in interarytenoid lesion and connection between esophagus and laryngeal lumen.
