CT indicated that a tumor had spread into the left sphenoid sinus, pterygopalatine fossa, pterygomaxillary
fissure, and infratemporal fossa (figure 4, A).
An anatomic study of the pterygomaxillary
region in the craniums of infants and children.
Stage IIB: Full occupation of the pterygomaxillary
fossa with or without superior erosion of orbital bones.
4) Other indications for a Caldwell-Luc approach include treatment of oro-antral fistulae and malignant exophthalmos, as an approach to biopsy the infraorbital nerve in cases of suspected perineural invasion by cancer; or to the orbital floor in the treatment of trauma; or to the pterygomaxillary
space for ligation of the internal maxillary artery in the treatment of resistant epistaxis.
All three types of Le Fort fractures disrupt the pterygomaxillary
In this process, the maxilla is distracted from the complete Le Fort I osteotomy line and the pterygomaxillary
8) A gingivobuccal incision can be added to attain access to the pterygomaxillary
CT and MRI scans demonstrated a palatal mass with base of tongue involvement and extension into the pterygomaxillary
fissure, pterygopalatine fossa and vidian canal leading to the cranial base.
4,8-10) Other findings include occlusion of the maxillary sinus infundibulum (secondary to retraction of the uncinate process against the inferomedial orbital wall), an enlarged middle meatus with lateral retraction of the middle turbinate, deviation of the nasal septum, and an increase of adipose tissue in the pterygomaxillary
MRI showed a markedly enhancing lesion extending into the pterygomaxillary
and infratemporal fossae and nasal cavity through the sphenopalatine foramen (figure, A).
The complications and presenting symptoms of cholesteatoma, which may occur as a result of the interplay between bone erosion and infection, are determined by the anatomic relationship of the maxillary antrum (including the orbit, nasal cavity, teeth, and mouth) and the pterygomaxillary
In this article, we describe a new case, which involved the right nasal cavity, ethmoid sinus, and pterygomaxillary
fossa and extended into the cranial cavity.
