Incidence and Radiological Findings of Incidental Sinus Opacifications in Patients Undergoing Septoplasty or Septorhinoplasty.

In patients undergoing septoplasty or septorhinoplasty, the incidence of incidental sinus lesions was approximately 28.8% (107/372). This results indicate that preoperative CT in patients undergoing septoplasty or septorhinoplasty might be helpful to surgeons not only for better understanding the anatomical detail but also for detecting hidden paranasal sinus disease.
