Normal Ear Anatomy
Frank's sign or Frank sign is a diagonal ear lobe crease (ELC) extending diagonally from the tragus across the lobule to the rear edge of the auricle.[1]
It has been hypothesised that Frank's sign is a sign of cardiovascular disease[2] and/or diabetes. Some studies have described Frank's sign as a marker of cardiovascular disease but not linked to the severity of the condition.[3] In contrast, other studies have rebutted any association between Frank's sign and coronary artery disease.[4]
Some studies have focused upon bilateral ELC.[5]
The sign is named after Dr. Sanders T. Frank.[citation needed]
