Abstract

Superior Oblique muscle is innervated by the trochlear nerve. It can be congenital or acquired (traumatic, inflammatory, infectious or following sinus surgery). Damage to trochlear nerve can occur in the dorsal midbrain, cavernous sinus, superior orbital fissure and the orbit. Superior oblique is an intorter, depressor and abductor. Palsy of the muscle causes hypertropia, excyclotropia, esotropia and abnormal head postures including head tilt and face turn to the contralateral side. Facial asymmetry (shallowing of the mid facial region between the lateral canthus and the edge of the mouth) is a characteristic sign of congenital superior oblique palsy.
