Total endoscopic excision of branchial cyst in a child aged 3 years
- Branchial cyst excision endoscopy.
- Axillary approach-no neck incision.
- First ever in a child.
This is the case report of a three-year-old female Arab child who presented with a neck swelling since one year of age. Physical examination was suggestive of a 6 × 4 cm swelling in the right lateral neck, which was dumbbell shaped, deep to sternocleidomastoid muscle on either side of the muscle. Ultrasound scan revealed a large cyst with internal echoes in the right carotid space anteriorly. The cyst was dissected endoscopically by an axillary approach and complete excision was achieved, thus avoiding the need for a large incision in the neck. No complications noted after treatment. The lowest age at which branchial cyst excision was carried out endoscopically was 18 years as per the available literature. Hence this case seems to be the first ever endoscopic branchial cyst excision in the pediatric age group.
A branchial cyst is a congenital epithelial cyst on the lateral aspect of the neck, due to failure of obliteration of branchial cleft during embryonic development. It is the most common congenital cause of a neck mass. Though congenital, it may present at a later date due to secondary infection. The definitive treatment is surgical excision of the entire cyst wall.
Presently, the principles of remote access and endoscopy are combined together and are used regularly for removal of thyroid masses. In literature there is a case report of endoscopic branchial cyst excision in a patient aged 18 years . We hereby report a case of endoscopic branchial cyst excision in a 3-year-old child via axillary approach without a neck incision. This case seems to be the first ever endoscopic branchial cyst excision in the pediatric age group.
