[Effect of lamina papyracea ingression on orbito-ocular complications after functional endoscopic sinus surgery].
OBJECTIVE
To observe the effect of lamina papyracea ingression on orbito-ocular complications after functional endoscopic sinus surgery (FESS).


METHODS
Data of computed tomography (CT) and post-FESS complications were analysed in 483 patients undergoing FESS from October 2013 to November 2015. According to the condition of lamina papyracea, these patients were divided into lamina papyracea ingression group (ingression group) and normal group. All data were analyzed to observe the effect of lamina papyracea ingression on orbito-ocular complications.


RESULTS
The patients with lamina papyracea ingression were found to be 11.2 % (54/483). Of the 54 patients, 18 had grade-Ⅰlamina papyracea ingression, 25 had grade-Ⅱlamina papyracea ingression and 11 had grade-Ⅲ lamina papyracea ingression. The incidence of orbito-ocular complications in normal group was 2.6% (11/429) and the incidence of orbito-ocular complications in the ingression group was 16.7% (9/54). The difference was significant(χ(2)=20.61, P<0.01) CONCLUSION: Before FESS, the paranasal sinus CT should be carefully reviewed to find if there is lamina papyracea ingression, so as to avoid the orbito-ocular complications.
