“…It was a type III laryngeal cleft. 1 Patient was then operated for the cleft using the anterior laryngofissure approach. Tibial periosteum was used as an autograft and kept in the cleft and mucosa sutured over it on both sides.…”

When the tracheoesophageal septum fails to develop or fuse, a laryngeal cleft is formed. It may or may not be associated with a tracheoesophageal fistula. Diagnosing a laryngeal cleft is not straightforward as was found to be in this case. Here, the cleft was masquerading as a laryngeal polyp, which resulted in misdiagnoses and delay in the management. A false cord retractor was of significant help in diagnosing the cleft. We recommend the use of this instrument during evaluation of laryngobronchoscopy in all patients suspected to have a laryngeal cleft.

“…HENDIDURAS LARINGOTRAQUEALES Se trata de una patología poco común que representan el 0.5 al 1.5% de las anomalías congénitas laríngeas [46]. Se define como un defecto de la pared entre la vía aérea laringotraqueal y el tracto digestivo superior.…”

“…They can be classified depending on the extent of the affected airway, reaching from rather simple interarytenoid clefts (type I) to extensive laryngotracheal defects with a complete split of the trachea extending to one main bronchus (21). The child's symptoms are based on the extent of the cleft.…”

The pediatric airway-general implicationsThe pediatric airway has several distinct features compared to the adult airway. First, dimensions are much smaller. This is particularly important with regards to the subglottis. The inner-diameter of the subglottis of a newborn usually measures between 3 and 4 mm (1). A pathological process in this area, leading to a circular lumen reduction of only one millimeter, can result in a life-threatening near-occlusion.A second feature of the pediatric airway is that the cartilaginous parts are still malleable and cannot provide the same stability as an adult airway skeleton. This can become a problem after airway reconstructions and usually results in the need of prolonged postoperative stentings to support a laryngotracheal repair. The lack of stability of the trachea in a newborn (compared to an adult) also makes it more prone to develop tracheomalacia. Vessel malformations (vascular rings) can apply pressure to the airway, causing dynamic collapse and making surgical correction often inevitable (2).On the other hand, the flexibility of the pediatric trachea facilitates long-segmental resections. In children, up to 50 percent of the airway length can be resected without extensive tension on the anastomosis (3).With regards to the functional aspects of the pediatric larynx, the anatomical relationship between the glottis and the hyoid is also a unique feature. The thyrohyoid membrane is shorter than in adults and the thyroid notch usually projects behind the hyoid. This high location of the larynx raises the tip of the epiglottis behind the uvula, thus, permitting simultaneous breathing and swallowing (4). Consequently, swallowing problems are rare in children and the pediatric larynx can handle even profound changes in its configuration. In fact, extensive laryngotracheal resections and reconstructions are possible without risking severe postoperative swallowing problems. Diseases of the pediatric airway Laryngotracheal stenosisAirway injury secondary to traumatic intubation remains the most common cause of laryngotracheal stenosis, accounting for about 90% of all pediatric acquired airway stenosis (5). The majority of intubation-related injuries are due to the comorbidities. This comprehensive review should give an overview on most common airway problems in neonates and children as well as available surgical techniques.
