I Think trochlear too because torticollis is a dysfunction of basal ganglia, and the nerve closest is trochlear???

Correct Answer b is the answer

yes, B) trochlear nerve is the right answer

torticollis or wry neck is caused majorly by damage to sternocleidomastoid muscle(congenital type----no innervation pathway is affected---it arises due to sternocleidomastoid tumor) in the neck....physical examination of it can see as--decreased rotation and bending of the neck opposite to the affected side

spasmodic torticollis is assciated with basal ganglia lesion....which can be treated by botulinum toxin injections

acquired can be associated with many causes ..worth to remember is phenothiazine antipsychotics..

cranial nerve 11---lesion causes cervical dystonias and torticollis

cranial nerve 4-----trochlear nerve lesion cause sup. oblique muscle innervation lost( unable to read newspaper or unable to come downstairs).......if torticollis is suspected in a children ,ophthalmological examination is necessary,.. coz @dr_mhm said people tilt the head to overcome the diplopia caused by 4th nerve damage....


a) trigeminal-----affects face region mainly(as mandible,ophthalmic and maxillary branches)
c) d) glossopharyngeal and hypoglossal innervates the tongue....and no innervation pathway is affected in torticollis
e) facial-----facial paralysis(bell's palsy)..innervate taste sensation from ant. 2/3rds too..and also stapedius muscle too
f) abducens------innervate lateral rectus-----due to it's short course...rarely involves with much symptoms-----diplopia alone is seen


other congenital associations of torticollis------CDH, club foot
