Abstract
Extended draf iib procedure in the treatment of unilateral frontal malignant tumor
Highlights
Surgical resection is the main choice for sinonasal benign or malignant tumors
Computed tomography displays a mass with central necrosis infiltrating the maxillary, ethmoid and frontal sinus; the medial maxillary wall is decayed and left frontal sinusitis is notable (Figure 2)
To drain co-existed contralateral frontal sinusitis and gaining adequate marging, we extended Draf IIb procedure by removing lower intersinus septum, the lesion inside the frontal sinus doesn’t infiltrate to the sinusal mucosa can be removed (Figure 3)
Summary
Surgical resection is the main choice for sinonasal benign or malignant tumors. Draf III procedure can be performed to access the lesion inside the frontal sinus. In the case of confined, predominantly unilateral lesions, Draf IIb procedure provides wide access to the frontal sinus. This approach can be extended without destruction of the contralateral frontal sinus drainage pathway
