Fissured Tongue

Fissured tongue is a condition frequently seen in the general population that is characterized by grooves that vary in depth and are noted along the dorsal and lateral aspects of the tongue.


 Fissured tongue affects only the tongue and is a finding in Melkersson-Rosenthal syndrome, which consists of a triad of fissured tongue, granulomatous cheilitis, and cranial nerve VII paralysis (Bell palsy)



United States: ~ 2-5% of the population.

International:  21% worldwide population.

Fissured tongue is a totally benign condition and is considered by most to be a variant of normal tongue architecture.
