Otic Tumors
Malignant otic tumors
Basal cell and squamous cell carcinomas may arise in the ear canal. Persistent inflammation caused by Otitis Media (Chronic Suppurative) may predispose to the development of squamous cell carcinoma. Extensive resection is indicated, followed by radiation therapy. En bloc resection of the ear canal with sparing of the facial nerve is done when lesions are limited to the canal and have not invaded the middle ear. Deeper invasion requires a more significant temporal bone resection. These resections are typically done by surgeons specializing in neurotology or skull base surgery. Rarely, squamous cell carcinoma originates in the middle ear. The persistent Otorrhea of chronic otitis media may be a predisposing factor. Resection of the temporal bone and postoperative radiation therapy are necessary. Nonchromaffin paragangliomas (chemodectomas) arise in the temporal bone from glomus bodies in the jugular bulb (glomus jugulare tumors) or the medial wall of the middle ear (glomus tympanicum tumors). They appear as a pulsatile red mass in the middle ear. The first symptom often is Tinnitus that is synchronous with the pulse. Hearing loss develops, followed by
