This article documents the existence of three structures that traverse
through the petrotympanic fissure. These structures are the mandibula
r malleolar ligament, the chorda tympani nerve and the anterior tympan
ic artery. The mandibular malleolar ligament or the disk-malleolar lig
ament originates on the anterior process of the mallous. It traverses
through the petro-tympanic fissure and attaches to the posterior porti
on of the capsule and disk of the temporomandibular joint. The chorda
tympani nerve supplies sensory feeling to the posterior two thirds of
the tongue. The anterior tympanic artery supplies blood to the area of
the tympanic membrane. Clinical experience with implants that impinge
or cover ear problems and other symptoms. Removal of these implants a
nd placements with devices that do not cover these structures often re
lieve these symptoms.
