ABSTRACT
OBJECTIVES:
The authors investigated the olfactory fossa (OF) in patients with unilateral nasal septal deviation (NSD) and presented the lateral lamella-cribriform plate angle (LLCPA).METHODS:
Paranasal sinus computed tomography images of 300 adult subjects with unilateral NSD (111 males, 189 females) were evaluated retrospectively. Septal deviation angle (SDA), Keros Classification, OF depth and width, LLCPA; and orbital plate and cribriform plate (OPCP) distance were measured.RESULTS:
The OF depth values (ipsilateral, contralateral) were found as Keros III >Keros II >Keros I (Padjustedâ<0.0175). The OF width values (ipsilateral) were detected as Keros I >Keros II and Keros I >Keros III (Padjustedâ<0.0175). In patients with higher SDA values, ipsilateral OF depth values decreased (Pâ<0.05). The LLCPA and OPCP values were higher in Keros I and lower in Keros III (Pâ<0.05).CONCLUSION:
In patients with lower LLCPA and OPCP, endoscopic sinus surgery will be more dangerous for trauma to lateral lamella and intracranial penetration.
