“…Lesions in the infratemporal fossa are rare but are challenging pathologies for physicians (Gates, 1988; Wetmore et al, 1986). Over the last few years, close collaborations between neurosurgeons and otorhinolaryngologists have made it possible to reach and treat various lesions of the infratemporal fossa.…”

The objective of this study is to clearly and precisely describe the topography and contents of the infratemporal fossa. Ten formalin-fixed, adult cadaveric specimens were studied. Twenty infratemporal fossa were dissected and examined using micro-operative techniques with magnifications of 3-40×. Information was obtained about the inter-relationships of the contents of the infratemporal fossa. The infratemporal fossa lies at the boundary of the head and neck, and the intracranial cavity. It is surrounded by the maxillary sinus anteriorly, the mandible laterally, the pterygoid process anteromedially, and the parapharyngeal space posteromedially. It contains the maxillary artery and its branches, the pterygoid muscles, the mandibular nerve, and the pterygoid venous plexus. The course and the anatomic variation of the maxillary artery and the branches of the mandibular nerve were demonstrated. The three-dimensional (3D) relationships between the important bony landmarks and the neurovascular bundles of the infratemporal fossa were also shown. The skull base anatomy of the infratemporal fossa is complex, requiring neurosurgeons and head and neck surgeons to have a precise knowledge of 3D details of the topography and contents of the region. A detailed 3D anatomic knowledge is mandatory to manage benign or malignant lesions involving the infratemporal fossa without significant postoperative complications.

“…Various operative approaches have been described for the surgical resection of trigeminal neurinomas [5,16,18,19]. Skull base techniques have recently been utilized [1,3,7,15] to provide for a low and wide exposure and limiting the need for brain retraction.…”

A small craniectomy in the infratemporal fossa incorporating the foramen ovale was used to resect 4 large trigeminal neurinomas. The tumour extended from the posterior cranial fossa and involved Meckel's cave and the lateral wall of the cavernous sinus in each instance. The dural sheath around the mandibular nerve and Gasserian ganglion was opened to expose the entire lesion. The head position and the surgeon's view of the tumour were modified to obtained a basal view. The craniectomy at this strategic site provided an avenue for control of the carotid artery at the petrous apex, avoided the need for brain retraction and permitted safe and complete resection of the tumours. The approach appears to be ideal for selected cases of trigeminal neurinomas.

“…9 The preauricular approach to the ITF was developed and modified with these concepts in mind. 10,11 This surgical approach is suitable for the resection of tumors arising in ITF and for intracranial tumors arising in the boundaries of the anterior temporal bone or greater wing of the sphenoid and extending into the ITF. It does not allow, however, the safe resection of any portion of the tympanic bone.…”

Preauricular Infratemporal Fossa Surgical Approach: Modifications of the Technique and Surgical Indications

A retrospective clinical analysis was performed to evaluate the effectiveness of the preauricular infratemporal fossa (ITF) surgical approach using modifications based on tumor pathology and extension, without compromising outcomes. Patients were surgically treated for tumors involving the ITF via a preauricular surgical approach during 1990 to 2000. Their clinical charts were reviewed to determine the association among pathological variables, details of the surgical procedure, and outcomes. Tumors in 65 patients were categorized as ''malignant'' and ''benign.'' The malignant group included 44 patients (mean age, 49.5 years). Squamous cell carcinoma was the most common pathology followed by sarcomas. To achieve complete tumor resection, the ITF approach and dissection were combined with other procedures in 74% of these patients. No surgical complications were encountered in 74.4%, and a clinical cure was obtained in 55% of patients (follow-up, 2 years). The benign group included 21 patients (mean age, 36.7 years). Juvenile angiofibromas and meningiomas constituted most of the tumors in this group. An ITF approach alone was sufficient to achieve complete tumor excision in 66.7% of these patients. A clinical cure was achieved in 85% of patients (follow-up, 2 years), and 76.2% had no surgical complications. Chi-square tests revealed significant correlations between tumor extensions and surgical treatment variables. These were more evident in the malignant group, indicating the use of wider surgical exposures and more aggressive, extirpative surgery. The preauricular surgical approach to the ITF can be used to achieve a complete resection of a variety of tumors arising from or extending into the ITF. This approach can be tailored to the nature of the tumor and its extensions.
