Control of a Jugular Bulb Bleeding in Endoscopic Ear
resulting from the aberrant carotid artery or sigmoid sinus injury. The first reported case of jugular bulb bleeding was by Page in 1914 on a 10 months old girl during myringotomy procedure . Radiologically, a study looking into 2020 temporal bone computed tomographies (CT) showed a high jugular bulb in 15% and dehiscence in 7.5% .

Assessment of the soft palate with oral and fiberoptic examination will detect any soft palate muscle Myoclonus. Auscultation in the region of the temporal bones, orbits, neck, and chest is essential.

Internal carotid artery Variations Dissection A B S T R A C T Background: The Internal carotid artery (ICA) is one of the branches arising from the Common carotid artery. A study of variability in the origin and course of the cervical part of the ICA is clinically important for vascular surgeons in performing certain stenting procedures.

the carotid artery in the middle ear is a prolapsed not aberrant carotid artery (Figure 2). Patients with OI disease characterized by having brittle bones for that, the chance of getting spontaneous bone fractures is very high. Histopathologic studies of 8 temporal bones from 5 patients of OI, showed evidence of
Patulous eustachian tubes and an unusual case of fused
carotid arteries and the proximal ICA, while the cranial part of the dorsal aorta gives rise to the distal ICA. The external carotid arteries sprout from the common carotid arteries and receive contributions from the first and second aortic arches (Figure 6a and b). As the dorsal aorta descends into the chest, the course of the ICA straightens out.

An aberrant internal carotid artery (AICA) is a rare vascular anomally that internal carotid artery (ICA) takes in an aberrant lateral course in the temporal bone and passes through the middle ear cavity . It is generally accepted to be a collateral pathway that occurs as a result of agenesis of first embryonic segment of the ICA. (Figure 4) 240
