Figure 4
Endoscopically controlled resection. Operation started as a common functional endoscopic sinus surgery including clearing out the ethmoid cells and identifying the frontal sinus and the maxillary sinus. Upon resection of the dorsal part of the septum, a pedicled tumor insertion at the rhinobasis and the lateral nasal wall was found. The tumor’s feeder vessels were exhibited. The vessels originating from the arteria sphenopalatine were specifically identified and clipped ((a), (b); →). The tumor was completely resected using four hands technique ((c), (d)). Maxillary sinus (SM), sphenoid sinus (SS), and tumor (*).
