Laryngotracheoesophageal cleft

We present a case of a preterm neonate with a type IV laryngo-tracheo-oesophageal cleft, an uncommon congenital malformation, resulting from the failure of separation of the trachea and the oesophagus during fetal development, often associated with other deformities as well. Data in the literature shows that the long-term morbidity from the entity has declined over the last decades, even though prognosis remains unfavourable for types III and IV. This report emphasizes the complex issues neonatologists are faced with, when treating neonates with this rare disorder in the first days of life, what will raise suspicion of this rare medical entity, and that direct laryngoscopy/bronchoscopy finally depicts the exact extension of the medical condition...

<b/>Congenital laryngeal cleft is a rare airway malformation, mainly manifested as choking, feeding difficulties, which affects the growth and development of children. Patients with a severe laryngeal cleft may have recurrent aspiration, leading to cyanotic spells, or even death. Advances in development of endoscopic techniques have made early diagnosis possible. Depending on the degree of cleft, management may involve a variety of approaches ranging from medical management alone to open repair. Therefore, it is important for pediatric ENT doctors to diagnose and evaluate in clinical practice...

BACKGROUND: Laryngotracheoesophageal cleft (LTEC) is a rare disease in which the larynx and trachea communicate posteriorly to the esophagus. It is often associated with other congenital malformations, particularly gastrointestinal anomalies. Herein, we report a case of LTEC associated with a gastric polypoid lesion in bronchial tissue. CASE PRESENTATION: A gastric mass was detected in a male fetus since week 21 of gestation using fetal ultrasonography. Esophagogastroduodenoscopy performed after birth revealed a pedunculated polypoid lesion of the gastric fornix...

Objective: Our aim of this study is to describe the outcomes of a series of patients who underwent cleft repair and posterior cartilage grafts laryngotracheoplasty (LTP) from anterior midline cervical approach for type Ⅲ laryngotracheoesophageal clefts (LETC). Methods: A review of patients with type Ⅲ LETC between May 2017 and December 2021 was performed. Demographic features including gender, age at surgery, weight, airway support, feeding status, and airway and other comorbidities were collected preoperatively...

Objective: To investigate the clinical diagnosis and treatment of congenital laryngotracheoesophageal cleft (LTEC) in children. Methods: The clinical data of 8 children (including 7 males and 1 female)with congenital laryngotracheoesophageal cleft from January 2016 to June 2020 were retrospectively analyzed. The median diagnosing age was 3.75 months (5 days to 12 months). According to the modified Benjamin Inglis classification proposed by Sandu in 2006,there were 3 cases of type Ⅱ, 3 cases of type Ⅲa, 1 case of type Ⅲb and 1 case of type Ⅳa...

OBJECTIVES/HYPOTHESIS: Determine surgical and swallowing outcomes after surgery for type III laryngotracheoesophageal cleft (LTEC). STUDY DESIGN: Case series with chart review. METHODS: Chart review was performed on patients with type III LTEC between 2000 and 2019. Demographics, surgical outcomes, and swallowing outcomes were collected and analyzed. RESULTS: Thirty-three patients met inclusion criteria (28 open and 5 endoscopic repairs)...

Laryngotracheoesophageal clefts (LTECs) and tracheoesophageal fistulae (TEF) are important structural causes of aspiration requiring bronchoscopy for diagnosis. Determining which children are at greatest risk for LTEC and TEF would enable clinicians to be more selective in performing bronchoscopy. METHODS: Medical records of children aged 0-18 years who underwent flexible and rigid bronchoscopy for evaluation of dysphagia with aspiration were collected and analyzed to identify predictors of LTEC and TEF...

Laryngeal webs and laryngotracheoesophageal clefts (LTECs) are rare malformations of the larynx. Both can have a wide range of symptoms. While webs typically affect voice and airway and LTECs typically affect swallowing and airway, this is not always the case. A high index of suspicion is required for timely and accurate diagnosis. A discussion of management and treatment options will be presented. Both endoscopic and open surgical techniques exist for both pathologies and will be reviewed.

Trachea-esophageal defects (TEDs), including esophageal atresia (EA), tracheoesophageal fistula (TEF), and laryngeal-tracheoesophageal clefts (LTEC), are a spectrum of life-threatening congenital anomalies in which the trachea and esophagus do not form properly. Up until recently, the developmental basis of these conditions and how the trachea and esophagus arise from a common fetal foregut was poorly understood. However with significant advances in human genetics, organoids, and animal models, and integrating single cell genomics with high resolution imaging, we are revealing the molecular and cellular mechanisms that orchestrate tracheoesophageal morphogenesis and how disruption in these processes leads to birth defects...

INTRODUCTION: Airway anomalies are accountable for a substantial part of morbidity and mortality in children with Down syndrome (DS). Although tracheal anomalies occur more often in DS children, a structured overview on the topic is lacking. We systematically reviewed the characteristics of tracheal anomalies in DS children. METHODS: A MEDLINE and EMBASE search for DS and tracheal anomalies was performed. Tracheal anomalies included tracheal stenosis, complete tracheal ring deformity (CTRD), tracheal bronchus, tracheomalacia, tracheal web, tracheal agenesis or atresia, laryngotracheoesophageal cleft type 3 or 4, trachea sleeve, and absent tracheal rings...

OBJECTIVE: To evaluate outcomes of injection laryngoplasty (IL) and endoscopic surgical repair for the treatment of type 1 laryngeal clefts (LC1) and to determine the most common presentations of LC1. METHODS: Primary studies were searched for in PubMed, Scopus, OVID, and Cochrane Library using search terms laryngeal cleft and laryngotracheoesophageal cleft for articles published from database inception through August 2019. The search identified all articles pertaining to the symptomatology and management of LC1...

PURPOSE OF REVIEW: This review summarizes the paediatric laryngotracheoesophageal cleft (LTEC) literature, with an emphasis on recent trends, evaluation and management, surgical techniques, postoperative care of Type III and IV LTECs, and to propose a revised cleft classification system that more accurately reflects our current understanding of these anomalies. RECENT FINDINGS: There are a number of techniques described to address Type III and IV LTEC, from endoscopic to open approaches with thoracotomy...

A laryngotracheoesophageal cleft (LC) is a rare congenital anomaly of the upper aerodigestive tract resulting from the absence of fusion of the posterior cricoid lamina, which affects an abnormal communication between the larynx, trachea and esophagus. The genetic etiology of LC remains elusive. The involvement of genetic factors in the development of LC is suggested by reports of familial occurrence, and the increased prevalence of component features among first-degree relatives of affected individuals and murine knockout models...

PURPOSE: A type IV laryngotracheoesophageal cleft (LTEC) is a very rare congenital malformation. Type IV LTEC that extends to the carina have poor prognosis and are difficult to manage. We present our experience with surgical repair in such a case using extracorporeal membranous oxygenation (ECMO). METHODS: A male infant, who was diagnosed with Goldenhar syndrome, showed severe dyspnea and dysphagia. Laryngoscopy indicated the presence of LTEC. The patient was transferred to our institute for radical operation 26 days after birth...

The causes of embryological developmental anomalies leading to laryngotracheoesophageal clefts (LTECs) are not known, but are proposed to be multifactorial, including genetic and environmental factors. Haploinsufficiency of the RERE gene might contribute to different phenotypes seen in individuals with 1p36 deletions. We describe a neonate of an obese mother, diagnosed with type IV LTEC and type III esophageal atresia (EA), in which a 1p36 deletion including the RERE gene was detected. On the second day of life, a right thoracotomy and extrapleural esophagus atresia repair were attempted...

A laryngotracheoesophageal cleft, commonly called laryngeal cleft (LC), is a congenital malformation of the posterior part of the larynx creating an abnormal communication between the laryngotracheal axis and the pharyngoesophageal axis. The prenatal ultrasonographic features associating absent stomach, polyhydramnios and mediastinal "pouch sign" are usually considered pathognomonic for esophageal atresia. This observation demonstrates that they can also correspond to a severe form of laryngotracheoesophageal cleft extending to the carina...

Laryngotracheoesophageal cleft is a rare congenital malformation where a communication exists between the aero-digestive tracts that is associated with high morbidity and mortality. In this case series, we describe our experience with two neonates evaluated in our institution with two diverse initial presentations and symptomatology of type IV laryngotracheoesophageal clefts. One patient presented with acute distress and respiratory failure due to bowel contents obstructing the trachea and the other presented with mild subcostal retractions and inspiratory stridor without overt respiratory failure...

Laryngotracheoesophageal cleft (LTEC) is a rare anatomic cause of aspiration in the newborn and infant. The clinical presentation of infants with LTEC is variable and will usually vary with the degree of anatomic communication between the airway and esophagus. The diagnosis of LTEC is often challenging, particularly in cases where the presentation and pathology are more subtle. Management of LTEC depends upon the clinical presentation, degree of aspiration, and anatomic depth of the cleft. The goal of this review is to present the clinician with a practical approach to diagnosis and management of this rare but challenging congenital airway anomaly...
