Infratemporal fossa and lateral skull base dissection: long-term results.
In 1981, we described a new surgical technique featuring en bloc removal of infratemporal fossa malignancies. This approach offered a systematic resection of cancers in this region and was designated "stylohamular dissection" because the medial boundary of the bloc is surgical plane between the styloid process and the hamulus of the pterygoid. All structures lateral to this plane are removed, sparing the internal carotid artery. Since 1977, twenty infratemporal fossa and lateral skull base dissections have been performed for palliation of metastatic or recurrent disease in the infratemporal fossa. Most patients obtained palliation of trismus, facial pain, or relief from an unmanageable ulcerating lesion. This technique offers improved average disease-free intervals, as well as enhanced survival rates compared to non-en bloc resections. A summary of the case presentations, survival statistics, and surgical technique with detailed cadaver dissections are presented.
