“…Excessive aural bleeding during myringotomy is a serious complication that has been reported. 1,2 Although one of the most common factors is high jugular bulb, this complication is frequently related to problems with the internal carotid artery (ICA) as it ascends through the temporal bone: Aberrations include aneurysm or herniation of the ICA in the middle ear through a dehiscence of the carotid canal wall (CCW), which is the medial wall of the bony portion of the eustachian tube (ET). 1,2 It has also been reported that, in some cases, CCW is extremely thin; occasionally, a dehiscence has been observed.…”

Objective The objective was to examine the possible risk of injury to the internal carotid artery during procedures in the middle ear, including myringotomy. Study Design Histopathological morphometric study of human temporal bones. Methods One hundred forty‐two human temporal bone specimens obtained from 92 individuals without any known ear disease were prepared for light microscopic study. Using 83 bones that were available for measurement, the thickness of the carotid canal wall (CCW), which is the medial wall of the bony portion of the eustachian tube, was measured. Using 15 bones selected for three‐dimensional measurement, the closest distance from CCW to the anterior tympanic annulus was measured. Using all 142 temporal bone specimens, the CCW was examined to detect the presence of partial dehiscence. In one case, the images of CCW dehiscence and its surrounding structures were reconstructed by a personal computer. Results The thickness of the CCW was 0.00 to 0.73 mm (average thickness, 0.24 mm [±0.12 mm]). The distance from the CCW to the anterior tympanic annulus was 1.8 to 8.1 mm (average distance, 4.9 [±1.7 mm]). Dehiscence of CCW was observed in 7 (4.9%) of 142 temporal bone specimens. The reconstructed image showed that the posterior half of the dehiscence of CCW could be seen from the external ear canal. Conclusions The CCW was found to be extremely thin or even dehiscent in some cases, rendering the internal carotid artery vulnerable during transtympanic procedures. The study's findings emphasized the need for judicious care when operating in the anterior mesotympanum.

“…[7,15] Revascularization of the carotid artery using a cervical to middle cerebral artery vein bypass graft may be necessary to provide immediate restoration of high blood flow and to reduce the risk of morbidity and mortality caused by acute ischemic complications. [1,11] Searching through the literature, there are seven reported cases of ruptured pseudoaneurysm caused by chronic otitis media.…”

Fig. 1 Axial (A), coronal (B), and sagittal (C) computed tomography scans with contrast medium showing the destroyed petrous bone, the internal carotid artery and the aneurysm (arrow), which are exposed to the right middle ear, and a massive hematoma in the right middle ear. 578Neurol Med Chir (Tokyo) 50, 578¿580, 2010 AbstractA 60-year-old man presented with a rare case of pseudoaneurysm in the petrous internal carotid artery (ICA) caused by chronic otitis media manifesting as right otorrhagia after the earpick procedure. Computed tomography showed the destroyed petrous bone; the ICA and the aneurysm, which were exposed to the right middle ear; and a massive hematoma in the right middle ear. Right carotid angiography revealed a pseudoaneurysm arising from the ICA coursing through the middle ear. Two weeks later, the right ICA was trapped after external carotid artery-middle cerebral artery bypass surgery using a vein graft. A biopsy specimen was obtained from the middle ear and the histological diagnosis was inflammatory disease. Pseudoaneurysm often causes sudden massive aural bleeding. The appropriate management strategy may be exclusion of the pseudoaneurysm with revascularization to avoid leaving foreign material in the infected middle ear.
