ABSTRACT
La malformaciones de arcos branquiales constituyen la segunda causa de masa congénita de cabeza y cuello en niños. La presentación clínica depende del arco afectado, siendo las más frecuentes las de segundo arco branquial. Se presenta un caso clínico de un escolar de 7 años que consulta por disfagia lógica, evidenciándose una gran masa orofaríngea posterior a pilar faríngeo posterior izquierdo. El estudio de imágenes con tomografía computarizada (TC) y resonancia magnética (RM) de cuello mostró una lesión quística en relación al pilar faríngeo posterior izquierdo. Se realizó resección transoral de la lesión conservando su pared lateral. El estudio anatomopatológico resultó sugerente de quiste de segundo arco branquial. Se discute la presentación clínica, diagnóstico y alternativas de tratamiento de las anomalías de segundo arco branquial.
Branquial cleft malformations are the second cause of congenital mass of the head and neck in children. The clinical presentation depends on the cleft involved; second branchial cleft anomalies are the most common. There is a case of a 7 years old boy with a history of logic dysphagia, fisical examination shows a large oropharyngeal mass located behind the left posterior pillar of the pharynx. The imaging study with computed tomography (CT) and magnetic resonance imaging (MRI) of the neck showed a cystic lesion in relation to the left posterior pillar of the pharynx. Transoral resection of the lesion was performed keeping its lateral wall. Pathologic examination was suggestive of second branchial cyst. Clinical presentation, diagnosis and treatment options of the second branchial cleft anomalies are discussed.

Branchial cleft cysts, sinuses, and fistulae are classified as first, second, third and fourth branchial cleft anomalies. They represent the congenital anomalies resulting from defects in the normal maturation of the branchial apparatus. Second branchial cleft anomalies occur more commonly than other branchial cleft anomalies. Most branchial cysts from the second branchial cleft are found deep in the sternocleidomastoid muscle or along its anterior border. Recognizing and diagnosing lateral neck cysts correctly are not difficult for an expert physician, although an unusual localization may cause problems in differential diagnosis. Complete excision of branchial cleft cysts is necessary to avoid recurrence. Approaches to the lesions are depending on the location and extent of the lesion. This article presents an unusual case of parapharyngeal branchial cleft cyst extending the skull base. Excision of the lesion was achieved via the lateral transcranial infratemporal fossa approach with zygomato-temporal craniotomy. This approach provides access not only to all of the subcranial tissues that underlie the middle cranial fossa, but to the maxillary or sphenoid sinus.
