Endoscopic Prelacrimal Recess Approach Adjunct with Vestibular Sulcus Incision: Case Report of a Minimally Invasive Access to Remove Infratemporal Fossa Tumor

To remove tumor located at anterolateral-inferior of infratemporal fossa (ITF) with purely transnasal approach is still a great challenge because of the over lateral angulation. The aim of this study is to present our initial experience--endoscopic prelacrimal recess approach adjunct with vestibular sulcus incision as a simple and minimally invasive approach to remove tumor in this area. Tumor in anterolateral ITF can be well explored via endoscopic prelacrimal recess approach; a simple vestibular sulcus incision provides a second access for two-surgeon co-operation, so tumor can be removed conveniently with minimal invasion. It is a viable alternative to endoscopic extended medial maxillectomy approach or open approaches to this area.
