Abstract
The description of different endonasal drainage options (type I, II and III according to Draf) and their successful use in numerous patients has reached a milestone in frontal sinus surgery. We herein describe a modification of an endonasal frontal sinus drainage type IIb with the additional removal of the lower part of the frontal sinus septum without opening the frontal recess of the other side and without resection of the nasal septum. The modified endonasal endoscopic frontal sinus drainage type IIb was performed on 9 patients at the Department of Otorhinolaryngology, University Medical Center, Homburg/Saar between 02/2011 and 6/2013 after having gained patients’ consent. Follow-ups with endoscopic examination were performed after 6, 12 and 24 months (median follow-up: 14 months). Endonasal endoscopic opening of the frontal sinus was achieved in all patients. Endoscopic examination 6, 12 and 24 months after surgery revealed patent frontal sinus drainage in 8 patients. The frontal sinus drainage could not be visualized endoscopically in one patient who was free of symptoms for 24 months and where a ventilated frontal sinus was proven radiologically by computed tomography. The study demonstrates the option to additionally remove the lower part of the inter-frontal septum with a frontal sinus drainage type IIb. As the number of patients treated by this modified frontal sinus type IIb drainage is limited, further investigations are needed to define the value of a modified frontal sinus drainage type IIb.
