Summary
A rare vascular abnormality, intratympanic aberrant internal carotid artery (ICA), can cause hearing loss and tinnitus. This case highlights its combined occurrence with hypoplasia, emphasizing potential life-threatening complications.
Area of Science:
- Vascular abnormalities
- Otolaryngology
- Radiology
Background:
- Intratympanically aberrant internal carotid artery (ICA) is a rare vascular anomaly.
- It is infrequently recognized as a cause of tinnitus and hearing loss.
- Aberrant ICA can lead to severe complications, particularly during otologic procedures.
Observation:
- A case of combined aberrant and hypoplastic internal carotid artery (ICA) is presented.
- The condition was identified in a 28-year-old male with hearing loss and ear fullness.
- The aberrant ICA was located beneath the manubrium mallei.
Findings:
- Audiological and radiological studies confirmed the aberrant and hypoplastic ICA.
- CT and MR angiography were utilized for diagnosis.
- This presentation adds to the limited literature on this specific vascular anomaly.
Implications:
- Clinicians should consider intratympanic aberrant ICA in patients with unexplained hearing loss or tinnitus.
- Awareness of this anomaly is crucial to prevent potentially fatal bleeding during ear surgeries.
- Further research into the prevalence and management of aberrant ICA is warranted.

01:26Arteries of the Head and Neck
The human body's intricate network of arteries ensures that every organ system receives the necessary oxygen and nutrients for optimal function. The arterial network in the head and neck region is particularly complex, providing vital blood flow to the brain, eyes, and other critical structures. Prominent arteries in this region include the internal carotid arteries and the vertebral arteries.

01:10The Arch of Aorta
The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:25Cardiovascular System Abnormal Findings II: Auscultation
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.

01:30Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
01:22Aortic Regurgitation II: Clinical Features and Diagnostic Tests
Aortic valve regurgitation (AR) occurs when the aortic valve fails to close properly, allowing blood to flow backward from the aorta into the left ventricle. This backflow can result in two distinct clinical presentations: acute and chronic AR, each characterized by its own set of symptoms and physical findings.Acute Aortic RegurgitationAcute AR presents with a sudden onset of severe symptoms. Patients typically experience profound dyspnea (shortness of breath), chest pain, and signs of left...
