![]() ![]() ![]() Saccades to visual targets and yaw-axis optokinetic nystagmus did not provoke right ear cricket tinnitus. Head velocity measurements revealed that right ear cricket tinnitus was heard only when the yaw head velocity exceeded 600°/second ( Figure 1). The patient’s right ear cricket tinnitus could be evoked by yaw head rotations to either side, as well as by head rotations in the plane of his right superior semicircular canal but not in the plane of his left superior semicircular canal. Nystagmus was not provoked by the use of a noise box or the Valsalva manoeuvre. The use of Frenzel lenses resulted in no spontaneous, head-shaking or gaze-holding nystagmus. Somatic testing elicited no right ear cricket tinnitus, but intense left sternocleidomastoid muscle contraction provoked faint, high-pitched left ear tinnitus. The patient’s right ear cricket tinnitus was pitch-matched to 4 kHz. Right periauricular auscultation was negative even when the patient’s tinnitus was induced with rapid head turns. The patient’s ENT examination was unremarkable. He denied any hearing loss or vestibular symptoms. ![]() He also noted autophony in his right ear and sound distortion - specifically, tapping his teeth together was perceived as sounding like ‘a metal hammer on ceramic tile’.
