| Summary: | The transseptal approach to the maxillary sinus has been described for resection of extensive tumours of the nose and paranasal sinuses. We describe a modification of this method in a patient diagnosed with inverted papilloma for which he had undergone two previous operations. This method provides complete access to the maxillary sinus, particularly the anterior wall, to provide adequate reach and ensure complete removal of tumours. We describe a technique modifying the existing transseptal approach used as an adjunct to prelacrimal recess approach, wherein a hemitransfixation incision placed in the contralateral nasal cavity along the septum provides access to the maxillary sinus with angled instruments. This modified transseptal approach provided better reach and access to the maxillary sinus. Postoperatively, there was no evidence of septal scarring or perforation and no evidence of lesion recurrence. Our technique is an easy modification to the transseptal approach that is a useful tool to access hidden areas of the maxillary sinus without associated morbidity.
