Cancer originating from the external auditory canal (EAC) is rare, which precludes a clear understanding of the disease and its management approaches. We present an extremely rare case of bilateral auditory canal carcinoma that occurred heterochronously. Bilateral treatments resulted in good disease control and EAC structure preservation, which could accommodate various hearing aid options after cancer treatment. While disease control is the most crucial aspect to be considered when choosing a treatment of EAC cancer, one should also consider potential hearing ability in patients post-surgery, particularly in those with bilateral lesions, as it greatly influences the quality of life.
