“…3,10 In addition to the LeFort I maxillotomy approach, the extended maxillotomy approach accompanied by a midline sagittal split of both maxilla and the soft palate facilitates access to the CCJ. 11,21,23 In our series, one patient in whom total resection was achieved via by the transmaxillary approach has enjoyed RFS for more than 7 years without any complications. As an alternative to the transmaxillary approach, it should be determined whether a combined transoral-transsphenoidal approach will be adequate.…”

“…The transmaxillary approach is particularly suitable for extradural lesions extending into the sphenoid and the upper and middle clivus with minimal lateral extension. 11,16,30,39 Intradural tumors may be removed via the transmaxillary approach, but we prefer the lateral approach for those with intradural extension. The lateral boundaries are defined by the medial pterygoid plates, the ICAs at the level of the foramen magnum, the cavernous sinus, hypoglossal canals, and the jugular foramen.…”

Object The management of chordomas involving the skull base continues to present a number of treatment-related problems. Recently, both radical resection and charged-particle irradiation or stereotactic radiosurgery have reportedly been found effective for tumor control and for promoting a better quality of life in patients. In this article the authors analyzed the outcomes in 17 patients with skull base chordomas who were surgically treated at Kobe University Hospital between 1972 and 2000. Methods Preoperative radiological examinations included magnetic resonance imaging, computerized tomography, angiography, and balloon occlusion test of the internal carotid artery. Among the various surgical approaches used to remove the tumor were the frontoorbitozygomatic, transmaxillary, transcondylar, transsphenoidal, and the transbasal. Total removal was achieved in two (12%), near-total removal in three (18%), subtotal removal in nine (52%), and partial removal in three patients (18%). Since 1990, chordomas have been radically resected via various skull base approaches; the combined total or near-total removal rate has been 80% in this period. Radical removal of the tumors has not led to an increased risk. At the final follow-up review (mean 59.5 month), 75% of the patients were still alive, and 25% had died of chordoma recurrence. The overall recurrence-free survival rate was 82% at 3 years and 51% at 5 years. The 5-year recurrence-free survival rate in the five patients who underwent the operation during the past decade was 77% (mean follow up of 5.2 years). In two patients with recurrent tumors who underwent radiosurgery, no evidence of tumor regrowth was demonstrated at 3 years posttreatment. Conclusions The authors suggest that for the treatment of skull base chordomas radical resection is a key factor for longer survival and improved quality of life. Patients with sufficiently small tumors, which show a favorable configuration and location, can be suitable candidates for stereotactic radiosurgery.

“…Transtemporal approaches described by Fisch, preauricular approaches described by Schramm and Sekhar, and transmaxillary approaches described by Terz, Janecka, and Cocke validated the efficacy of and indications for this technique, and provided the framework for other modifications [3][4][5]. Recently, transnasal endoscopic and endoscopic-assisted approaches have been added to the armamentarium of skull base surgeons.…”

Using detailed cadaveric dissections this study has demonstrated and quantified the increase in exposure and additional access gained by using the orbitozygomatic infratemporal fossa approach for neurosurgical access. The surgical window of exposure can be increased by up to 300% when this technique is utilised to facilitate access via either a subtemporal (to access the P2 segment of the posterior cerebral artery) or transsylvian (to access the basilar bifurcation) approach. In addition the distance between the surgeon and the operative field can be decreased by approximately 2-3 cm. The orbitozygomatic infratemporal fossa approach is a relatively simple technique which can readily increase neurosurgical exposure of the skull base. It also provides simultaneous access to the infratemporal fossa, pterygopalatine fossa and the orbit.
