Aneurysms of the temporal bone.
Aneurysms of the internal carotid artery in the temporal bone are rare lesions which can present clinically as a growth in the middle ear cleft. Hemorrhage, occurring spontaneously or iatrogenically, is a primary concern. This study describes morphological and embryological characteristics of the internal carotid artery in relationship to the protympanum and temporal bone. Concepts of pathogenesis and pathology are discussed, with reference to the neurosurgical and otolaryngologic literature. Clinical characteristics, including methods of surgical repair, are presented using three illustrative case reports. Methods of surgical repair include: 1) reinforcement; 2) ligation; and 3) primary excision and reanastomosis.
