This panel will present a case-based approach to evaluation and management of ear canal masses. Panelists will be asked to navigate through cases that highlight principles of management. First, patient history and physical exam findings will be reviewed. Differential diagnosis of an ear canal mass will be discussed, including a review of benign and malignant lesions commonly found in the external auditory canal. Timing and preparation for biopsy will be discussed. Pearls and pitfalls of the workup of ear canal masses will be presented. Second, further studies to evaluate the mass will be discussed, specifically comparing the pros and cons of different imaging modalities. Timing of imaging in relation to biopsy will be examined. Third, treatment options will be reviewed, including medical management, office procedures and surgery when indicated. Finally, complications encountered during the evaluation and management of ear canal masses will be discussed. Key points to avoid pitfalls in the evaluation and management of ear canal masses will be demonstrated.
