OBJECTIVE: To describe surgical management for transcanal endoscopic ear surgery (TEES) in two patients with aberrant internal carotid artery (ICA) in the middle ear. PATIENTS: A young girl who complained of pulsatile tinnitus and an elderly man who presented with ear bleeding. Otoendoscopy examination revealed a pulsatile reddish mass protruding through the tympanic membrane in both patients. INTERVENTIONS: A combination of clinical assessments and imaging supported the diagnosis of aberrant ICA in the middle ear. Transcanal endoscopic reinforcement of the artery was performed; tragal cartilage was used as a shield to strengthen the carotid canal defect. RESULTS: Assisted by fine endoscopic instruments, the protruding arteries were separated without damage to the surrounding structures and reinforced using tragal cartilage. Both patients' symptoms improved postoperatively; they reported tinnitus relief and hearing improvement. CONCLUSION: To prevent catastrophic events, diagnosis of aberrant ICA is important before any surgical intervention. With appropriate management, surgical intervention using transcanal endoscopic ear surgery offers a clear view of the surgical field and is an excellent choice for management of aberrant ICA.
