Branchial Cleft Anomalies: Embryogenesis, Clinical Features, Diagnosis, and Management

Branchial cleft anomalies are congenital head and neck lesions that arise from incomplete maturation of the branchial apparatus during fetal development. The branchial arches are the precursors of the face, neck and pharynx, and disturbances in embryogenesis can present clinically as cysts, sinus tracts, and fistulas in predictable anatomic locations. However, there remains controversy regarding the precise embryogenesis of branchial cleft anomalies with several competing theories. These lesions often evade diagnosis in early childhood and may present in a delayed fashion after multiple failed interventions. Various diagnostic modalities have been described to facilitate clinical workup. Definitive treatment is complete surgical excision of the lesion. We present a comprehensive review of the literature along with several illustrative cases that highlight the unique challenges of diagnosis and surgical management of branchial cleft anomalies.

Branchial Sinus with Cyst - Two Case Reports with Review of Literature

Branchial cleft anomalies are well described, with the second arch anomaly being the commonest. Remains of cervical sinus of His may persist as a branchial cyst. A branchial sinus is formed when 2nd branchial arch fails to meet the 5th pharyngeal arch. Peak age for presentation of branchial cysts is in the third decade and that of the congenital sinuses and fistulae is at birth. The association of a branchial cyst with branchial sinus is very rare. We are presenting two cases had branchial cyst along with branchial sinus. It was managed successfully with complete excision. Histopathological examination confirmed the association.

Excision of rare adult cervical thymic cyst

Cervical thymic cysts (CTCs) represent 1% of all cervical cystic masses. A review of the literature found that CTCs are typically asymptomatic, with a propensity to be left sided. CTCs often require histological evaluation for diagnosis. A 27-year-old male patient presented to an outpatient otolaryngology clinic with worsening bilateral jaw and neck pain and an incidental right-sided neck mass found on cervical MRI. Preoperative differential diagnosis included venolymphatic malformation versus branchial cleft cyst. Histological examination of the excised specimen provided diagnosis of a CTC. Postoperatively, the patient reported improvement in cervical pain. CTCs are a rare cause of lateral neck mass in young adults. Typical presentation included neck enlargement with no symptoms or in some cases compressive symptoms. It is important to consider CTCs when formulating a differential for a lateral neck mass.
