Experience with the resection of parapharyngeal cancers via the infratemporal fossa approach.
Between 1982 and 1984, a modified infratemporal fossa approach was used to resect cancers with extensive primary or secondary involvement of the infratemporal fossa and parapharynx in 10 patients. Nine patients exhibited persistent or recurrent disease of the upper aerodigestive tract and posterior cranial fossa following planned, curative-intent therapy; the remaining patient had a carcinoma ex-pleomorphic adenoma of the deep lobe of the parotid gland with a significant infratemporal fossa extension. Considered to have "unresectable" tumors, by traditional methods, 7 of the 10 patients underwent an en-bloc resection of their lesions with tumor-free margins. Tumor was present at the margins of the specimens in the other 3 patients. Two of the 10 patients died early in the postoperative period of medical complications. Another died 5 months postoperatively of a tumor-induced internal carotid artery rupture at the level of the foramen lacerum. A fourth patient died of his disease 6 months following his resection. One patient is alive, but has metastatic meningioma 2 years after surgery. The 5 remaining patients are without evidence of disease, with a mean follow up of 2 years. Indications for and refinements of the operative technique, particularly those related to the repair of such extensive ablative defects, are outlined on the basis of this early experience.
