Temporal bone tumors can be characterized as benign or cancerous. These type of tumors are both extremely rare; however, cancerous tumors are alarming. Cancerous tumors are usually formed when the cancer of the skin invades the outer ear and ear canal. These cancers are most commonly squamous cell carcinoma of the ear, ceruminomatous adenoid cystic carcinoma, or adenoid cystic carcinoma of the ear.

The goal of these professionals is to provide the necessary information that will enable patients to participate in the decision making process. Afterwards, the team will develop a personalized plan for every patient.
