Wildervanck syndrome with hypoplastic frontal sinus: A rare case presentation.

We report a case of Wildervanck syndrome exhibiting Klippel–Feil anomaly, Duane’s retraction syndrome and congenital deafness. Since the first case was reported in 1952, there have been more reports describing this triad either complete or incomplete. Our case has a complete triad of the syndrome along with frontal sinus hypoplasia. Our case is unique as the triad was associated with frontal sinus hypoplasia, which is very rare association.
