Surgical Approaches To The Petrous Apex World Journal Of The petrous apex is a pyramidal shaped, variably pneumatized structure of the skull base that forms a unique intersection between the suprahyoid neck and the intracranial compartment. given its location, the petrous apex is susceptible to multiple pathologic processes including intrinsic lesions of bone, pneumatized air cells, or the petrous. Petrous apex pathology is usually found incidentally on imaging for unrelated symptoms. 15 symptoms, if present, are heterogeneous. the most common otolaryngologic complaint is hearing loss, but aural fullness and vertigo secondary to compression of the 8th cranial nerve are also common. 9, 16 these symptoms are present in approximately 65% of patients with petrous apex pathology 15.
Surgeries Around The Anterior Petrous Apex Youtube 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. The petrous apex is a pyramidal portion of the petrous part of the temporal bone [45, 46]. it is bordered superiorly and inferiorly by the petrous ridge that contains the superior petrosal sinus. S ince the introduction of kawase’s approach to the petrous apex (pa) in the mid 1980s, microscopic anterior petrosectomy has been recognized as a milestone pathway to various skull base lesions around the pa. 1–5 the pa is one of the most challenging areas in skull base surgery because it is surrounded by numerous critical neurovascular. Background and objective surgical approaches to the petrous apex region are extremely challenging; while subtemporal approaches and variations represent the milestone of the surgical modules to reach such deep anatomical target, in a constant effort to develop minimally invasive neurosurgical routes, the endoscopic endonasal approach (eea) has been tested to get a viable corridor to the.

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.
