The prognosis is worse when incomplete excision is seen at the infratemporal fossa and/or base of skull and therefore the anatomic site of involved margins must be clearly specified and marked on a diagram (Figure 9) during macroscopic and microscopic examination.
It has an average distance of 10.18 mm and 7.6 mm to the maxillary artery groove and maxillary nerve groove respectively, so it's an anatomical structure that should be considered as a parameter for the surgical approach of the infratemporal fossa and the neurovascular elements contained in it.
Reports have been suggested that there are higher possibilities of retained soft tissue tumour islands during the surgical procedure in the complex regions like infratemporal fossa [34, 35].
In the presented case, a watch-and-wait approach could not be adopted because the desmoid fibromatosis was symptomatic and was having an aggressive course, growing rapidly, and infiltrating the adjacent anatomical structures such as the lateral orbital wall, maxillary sinus, and temporal cavity and infratemporal fossa. Moreover, the neoplasia had already caused the loss of visual acuity in a short period of time.
This minimally invasive approach provided a safe and wide exposure of the lower clivus, anterior rim of the foramen magnum, C1 transverse process, occipital condyle, vertebral artery, posterior inferior cerebellar artery, and even the infratemporal fossa. It also allowed effective control of intraoperative extradural bleeding.
As for the extent, we recorded if the lesion involved the skull base and intracranial cavity in addition to the nasopharynx and infratemporal fossa. We compared the signal intensity of the lesions with that of the brain stem on T1-weighted and fat-suppressed T2-weighted images.
Sagittal reconstruction of CT (c) showed the long piece penetrating into the middle cranial fossa through infratemporal fossa. A small piece of bone fragment (hollow arrowhead, *) was noticed above the long piece.
Infection also may spread extracranially involving the infratemporal fossa, parotid, and neck, leading to the involvement of surrounding structures and formation of abscess [11].
The tumor is pushed superiorly into infratemporal fossa. The attachment of the parapharyngeal tumor to the infratemporal tumor was cut near the foramen ovale (Figures 4 and 5).
Abscess of the infratemporal fossa is a rare complication which can be difficult to diagnose.
Bodener et al14 reported a case of a teenage girl with a larger peripheral Osteoma of mandible occupying the infratemporal fossa, causing trismus and shift of the mandible on mouth opening.
On magnetic resonance imaging (MRI) there was a soft tissue density mass measuring 45x27x31 mmin CCxTxAP dimensions occupying left infratemporal fossa and left maxillary antrum, hypointense on T1, mixed signal intensity on T2 with significant post contrast enhancement.
