Intracranial and extracranial communicating tumors are tumors that grow intracranially and extracranially, destroying the bone at the base of the skull while invading the cranial nerves and blood vessels at the base of the skull. The relationship between intracranial and extracranial communicating tumors and the surrounding anatomical structures is intricate and complex, which may involve more organs (eye, ear, nose, throat, etc.) and treatment involves more disciplines (neurosurgery, ophthalmology and otorhinolaryngology, etc.). Tumors are usually large in size and rich in blood flow, making surgical operation more difficult and risky, and attention should also be paid to the protection of nerves and blood vessels and the reconstruction of bone and soft tissues at the base of the skull during surgery. The prognosis of intracranial and extracranial communicating tumors may be better if they are detected and treated early, which requires multidisciplinary joint treatment. It is recommended that patients should seek medical attention if they experience discomfort, such as abnormal masses in the head and face, in order to avoid delays.
