Abstract:
OBJECTIVE To recognize the frontal recess cells and analyze their distributional characteristics during image navigation assisted endoscopic sinus surgery. METHODS 20 cases(39 sides)of chronic sinusitis with nasal polyps were observed in this study. The fontal recess cells and frontal sinus were opened under the endoscope and the distributional characteristics were observed and recorded, and then confirmed by the image navigation system. RESULTS Centred on frontal sinus ostium, frontal recess cells were divided into three areas: the agger nasi cell(ANC)and frontal cells(FC)are located in front of frontal sinus ostium(FS); frontal septum cells(IFSSC)and terminal cells(RT)are located at the same plane of FS; supra-ethmoidal bulla recess(SBR), frontal bulla cell(FBC)and super-obital cells(SOEC)are in the posterior area. The coincidence of identification for ANC, FCI and II, SBR, FBC and IFSSC under endoscope and image navigation is 100%, the coincidence of identification for FS is 89.7%, SOEC 80%, RT 71.4% and FC III and IV 60%. CONCLUSION The distribution of the frontal recess cells around the frontal ostium showed a fixed pattern.It would well benefit the orientation of frontal ostium and the opening of frontal sinus. Furthermore, it is significant for the orientation and opening of the frontal recess cells.
