Surgical Approaches To The Petrous Apex World Journal Of The petrous apex remains one of the most challenging areas of the skull base to reach surgically, but with multiple possible approaches, skilled teams of otolaryngologists and neurosurgeons can safely manage petrous apex lesions. the choice of approach is determined by the nature of the pathology and location relative to vital structures and. Lesions of the petrous apex are difficult to resect due to their deep position within the skull base and close anatomical proximity to vital structures such as the internal carotid artery (ica), cavernous sinus, and meckel’s cave.4,20,21,22 certain lesions, such as cholesterol granuloma, can be managed with drainage while neoplastic lesions, for example, must be fully resected.20 surgical.
Lateral Skull Base Approaches And Surgical Management Of Petrous Apex Abstract. the petrous apex is a difficult to reach surgical area due to its deep position in the skull base and many vital surrounding structures. petrous apex pathology ranges from extradural cholesterol granulomas, cholesteatomas, asymmetric pneumatization, and osteomyelitis to intradural meningiomas and schwannomas. The approach gives wide access to the cpa and is suitable for large lesions with anterior extension into the prepontine cistern. the cavity is filled with fat. the approach is the widest surgical corridor in the lateral skull base, but is related to unavoidable morbidity of the facial nerve. The petrous apex (pa) is the pyramid shaped anteromedial portion of the petrous part of the temporal bone. the petrous bone is obliquely positioned within the skull base, with the apex located anteromedially and the base situated postero laterally. its anterosuperior surface forms the floor of the middle cranial fossa, while the posterosuperior.

Indications for use of it a approach are removal of the glomus temporal tumors involving the foramen jugulare, up to the size c4 de2 di1, removal of the cholesteatomas and aneurysms involving the petrous part of the ica and petrous apex, for intratemporal neuromas of cranial nerves ix–xii and for the lesions involving the skull base from.
