Nasofrontal masses belong to the group of congenital midface anomalies (CMFA) in paediatric age group. The usual list of differential diagnosis for such masses can be narrowed to Frontonasal dermoid, epidermoid, nasal encephalocele and nasal gliomas. Frontonasal dermoid with patent dermal sinus tract is a rare craniofacial anomaly resulting from the failure of normal embryonic development. Most of patients present in infancy or early childhood. CT, MRI and sinogram together are usually required for definitive diagnosis. Knowledge of embryonic development of nose & anterior skull base is important in understanding the pathologies of Frontonasal masses. Endoscopic ‘key-hole’ approach to these lesions via small incision allows better visualization & ensures complete removal.
