“…On X-rays taken in the frontal plane, the vertical segment of the artery always lies medial to a perpendicular drawn laterally to the vestibule. On the other hand, when it projects into the middle ear (auris media), the line of the artery crosses this perpendicular as confirmed by Glasgold (1972). The Eustachian tube and the canal of the tensor tympani muscle are situated anteriorly, parallel to the horizontal segment (Fig.…”

Summary. Anatomical characteristics of the internal carotid arteries are detailed in 50 anatomical preparations of frontal, sagittal and transversal sections from subjects aged between 42 and 76 years. The results obtained are compared with those reported in the literature and the following points are emphasized:Dimensions of the vessels (for the right internal carotid artery, the external diameter in the region of the neck was found to be 5_+0.8 mm, the mean length 154.9__+ 13.8 ram. There was no significant difference between left and right arteries).The variations in its course, with tortuousities at fixed points appearing relatively early in life, and their importance to arterial pathologies.The principal relationships of the cervical portion (C1), the petrous portion (C2), with the different parts of the ear and the cavernous portion of the artery (C3) in particular, and with the pituitary.

“…An emergency treatment in situations of severe bleeding requires packing of the ear canal and nasopharynx in case of nasal bleeding. 2 , 13 , 23 Even if the packing must be replaced and left in place for several weeks because of recurrent bleeding, 24 overpacking may damage the ICA and cause serious neurologic deficits. 19 Recurrent mild bleeding does not indicate intervention: ICA ligation in the neck, balloon occlusion, or embolization should be reserved for emergency situations to avoid possible severe complications or death.…”

An aberrant internal carotid artery (ICA) in the middle ear space can present in 1% of the population. the clinical diagnosis can be difficult as most patients with this anomaly are either asymptomatic or have nonspecific clinical symptoms and signs. Moreover the diagnosis can easily be missed and only discovered when injurey occur to the ICA during middle ear surgey with resulting life-threatning complications. A knowledge of this anomaly and its differential diagnosis is of high importance to any practitioner dealing with otologic diseases and performing otologic surgeries. We report a 7-year-old girl with a right aberrant ICA presenting with hearing loss and review published studies concerning this disease entity presentation, diagnosis, and management.

“…The vascular supply to the maxillary and mandibular regions comes from the external carotid artery. The course of ICA is different, normally the ICA ascends vertically, medial and anterior to the middle-ear cavity before bending sharply anterior and medially below the eustachian tube and cochlea, it then passes through the bony carotid canal in to the cranial cavity [10][11][12][13][14].…”
