Microsurgical anatomy of VII and VIII cranial nerves and related arteries in the cerebellopontine angle.
The relationships of VII and VIII cranial nerves and related arteries are reviewed in 26 preparations by microdissection techniques. These vessels may be grouped in large (AICA, PICA), medium (LA, SA, CSA, RPI) and small calibre (vasa nervorum, radicular and medullar branches). The importance of these structures in acoustic neuroma surgery, vestibular neurectomy and cross-compression syndromes is discussed. "Vascular loops" and "elongated arteries" are normal structures present at birth.
