Anterior_tympanic_artery
The anterior tympanic artery (glaserian artery[citation needed]) is a branch of (the mandibular part of) the maxillary artery.[1] It passes through the petrotympanic fissure[1][2] to entre the middle ear where it contributes to the formation of the circular anastomosis around the tympanic membrane.[2] It provides arterial supply to part of the lining of the middle ear.[1] It is accompanied by the chorda tympani nerve.[1]
