Can cerumen gland tumor of external auditory canal be saved?

When the tumor is located in the cartilage and the posterior wall of the bone of the external auditory canal, the resection scope should include most of the Tragus Cartilage, all the soft tissue of the external auditory canal, and the bone of the anterior, posterior and inferior wall of the external auditory canal. If the distance between the tumor and the tympanic membrane is less than 1.5cm, the tympanic membrane and the tumor should be removed in barrel shape.

When the tumor is located in the anterior wall of the cartilage part of the external auditory canal, the scope of resection should include all the soft tissues of the external auditory canal, parotid gland, preauricular lymph nodes and the adjacent bone of the anterior and posterior wall of the external auditory canal. If the tumor extends beyond the external auditory canal and invades adjacent tissues or organs, the extent of resection should be appropriately expanded according to the situation, and radical mastoidectomy or partial temporal bone resection should be performed at the same time.

The tumor is located in the bone and cartilage of the anterior wall of the external auditory canal. The resection range should include all the soft tissues of the external auditory canal, parotid gland, condyle and the bone wall of the external auditory canal adjacent to the tumor. If necessary, radical mastoidectomy should be performed.
