Clinical manifestations, diagnosis, and management of first branchial cleft fistula: Case series and review of the literature.

INTRODUCTION AND IMPORTANCE: The first branchial cleft (FBC) is an extremely rare occurrence, manifesting as cysts, sinuses or fistula. Among all branchial anomalies, FBC represents 8-10 % of branchial clefts. It accounts for about 17 % of all cervical masses in childhood. FBC can be caused by inadequate removal or closure of the ectoderm. The location of the fistula can be adequately determined by magnetic resonance imaging (MRI). CASE SERIES PRESENTATION: We report three cases from the first branchial cleft fistula (FBCF) in our ENT Department with a good response to surgical treatment. Patients had an average of 24 months of follow-up. The aim of our study is to study the clinical manifestations, the diagnosis and the surgical management of the FBCF. DISCUSSION: An in-depth knowledge of the embryology of the neck and face will ensure early diagnosis and complete surgical resection of FBCFs, which will minimize the risk of severe complications including facial paralysis. CONCLUSION: FBC is rare and may present as a cyst or fistula. It is managed by surgical excision, leaving the tract cyst of the fistula intact with preservation of the facial nerve.

Huge second branchial cleft cyst: A case report.

INTRODUCTION AND IMPORTANCE: Second branchial cysts are benign dysembryological cystic tumors that develop in the antero-lateral part of the neck. They represent 2 % of laterocervical tumors of the neck and are usually diagnosed before adulthood. The cysts can increase in size and cause multiple complications. Ultrasound and MRI (Magnetic Resonance Imaging) confirm their cystic nature. Treatment consists of surgical excision. CASE PRESENTATION: We report the case of a 31-year-old woman who presented with a left laterocervical swelling measuring 8 cm, which had been present for 18 months without any other associated symptoms. An exploratory cervicotomy was performed, and the histological diagnosis was a second branchial cleft cyst without signs of malignancy. CLINICAL DISCUSSION: The definitive diagnosis of a second branchial cleft cyst is confirmed by anatomopathological examination. Therapeutic management is always surgical and should be performed as early as possible to limit the risk of complications. CONCLUSION: Second branchial cleft cysts are relatively uncommon malformations. Diagnosis is suspected based on physical examination, guided by imaging data, and confirmed by anatomopathological examination. Treatment is surgical, with complete removal of the cyst being necessary to prevent recurrence.
