Our purpose was to discuss the optimal treatment and outcomes for patients with skull base chordomas.We reviewed the pertinent literature for this study.Skull base chordomas usually arise in the clivus and are rarely completely resectable. Therefore, most are treated with radiotherapy (RT).

Chordomas are rare, benign tumors of the nasopharynx. Because of their location at the skull base, removal of these tumors is usually subtotal. Described is the transcervical-transmandibular approach to the skull base which can be employed in removing these tumors.

Osteoradionecrosis of the skull base
Journal of Neuro-Oncology, 2020Radiation therapy (RT) is often necessary for the treatment of head and neck cancers. Osteoradionecrosis (ORN) is a rare, but potentially serious complication of RT. RT leads to the destruction of vasculature in radiated tissue causing hypoxia and tissue necrosis.

The Laryngoscope, 1982
AbstractEarly experience with medium to large tumors of the temporal region has re‐emphasized the value of radiologic preoperative plotting of these space occupying lesions in the sagittal, coronal, and horizontal planes. Attention to probable pathology, neurovascular structures and patient's medical status has been important in determining ...

Skull-base imaging has been a key factor in the advancement of skull-base surgery. The analysis of MR imaging or CT of the skull base emphasizes important landmarks, which are key to surgical planning. Although the definitive diagnosis usually is done by biopsy, the radiologist can limit the list of possibilities of the identity of a skull base lesion.

Otolaryngology–Head and Neck Surgery, 1986
Ten skull‐base neuromas treated at the Otology Group P.C. are presented. Each case is reported in detail. The method by which preoperative diagnosis was made is reviewed. Specific attention is paid to distinguishing these tumors from chemodectomas. Presenting signs and symptoms are enumerated.

Osteomyelitis of the Skull Base
Neurosurgery, 1992Three cases of osteomyelitis of the skull base with associated problems in diagnosis and therapy are discussed. Patients with atypical skull base osteomyelitis are difficult to diagnose as they have no ear abnormalities, but they often develop multiple cranial nerve deficits mimicking symptoms of a posterior fossa mass.

We report a case of a primary amyloidoma of the skull base. Plain radiography and CT showed a lytic, highly destructive lesion with multiple scattered calcifications within. MR imaging revealed that the tumor was isoto hypointense to muscle on T1-weighted images and extremely hypointense on T2-weighted images.

Neuroradiology of the Skull Base
Otolaryngologic Clinics of North America, 1984Newer imaging modalities, especially high resolution computed tomographic scanning, have radically altered and expanded the role of radiology in the evaluation and management of lesions affecting the skull base. The location, extent, and tissue characteristics of these lesions can be determined with greater precision than ever before.
