Background:
Pyriform sinus malformations represent rare third and fourth
branchial anomalies. They may be an unusual cause of
dysphonia in pediatric.
Case report:
A 6 year-old girl presented with dysphonia since birth with no
other
complain. Clinical examination revealed midline
cystic neck swelling 2x2 cm. Flexible laryngoscopy revealed left
vocal fold (VF) immobility with a cystic swelling
arising from medial wall of left pyriform fossa about 3x2 cm.
Computer tomography revealed midline subcutaneous cystic
swelling and submucosal cyst in the left pyriform. Transoral CO2
laser excision of the pyriform cyst was done with no
communicating tract and surgical excision of the neck cyst.
Histopathologic evaluation revealed pyriform branchial
cyst lined by pseudostratified columnar ciliated epithelium and
neck
epidermoid cyst. The patient showed post
operative improvement of dysphonia and the left VF mobility.
Discussion:
The present case is the first case to describe a Bailey's type IV
branchial cyst in the pyriform fossa. It is the
second branchial lesion transorally laser excised and the first
third branchial cyst reported. |
