[Juvenile angiofibroma predominantly extending into the middle cranial fossa and eye-socket].

The paper analyzes a rare case of juvenile angiofibroma primarily locating in the infratemporal and middle cranial fossa without a nodule in the nasopharynx. The tumor extended from the pterygopalatine fossa intracranially extradurally, by destroying the wing of the sphenoid bone. Since the disease has started from right facial hypesthesia, neurinoma involving the first and second branches of the trigeminal nerve and spreading to the eye-socket may be suggested. Destruction of the base of the skull is also typical of trigeminal neurinoma. It was sufficient to create an orbitozygomatic bone flap and to resect the remainders of the undestroyed part of the lateral part of the greater wing of sphenoid bone. Further tumor removal was effected through tumor-caused defect of the wing of sphenoid bone. A good functional and cosmetic effect and a 5-year relapse-free period lend support to the correctness of the chosen treatment policy.
