This review aims to familiarize the radiologist with the common types of sinus surgery including their indications and techniques. We also illustrate how surgeons interpret 3D sinus anatomy when evaluating computed tomography (CT) studies. Preoperative evaluation by CT is mandatory for all patients undergoing functional endoscopic sinus surgery (FESS). In the past decade in particular, CT of the paranasal sinuses has become a roadmap for FESS. The radiologist’s goal is to report on five key points: the extent of sinus opacification, opacification of sinus drainage pathways, anatomical variants, critical variants, and condition of surrounding soft tissues of the neck, brain and orbits. We present a systematic approach to the use of coronal, axial, and sagittal images in CT evaluation before FESS.

AIM: To define the 100 citation classic papers of interventional radiology. METHODS: Using the database of Journal Citation Reports the 40 highest impact factor radiology journals were chosen. From these journals the 100 most cited interventional radiology papers were chosen and analysed. RESULTS: The top paper received 2497 citations and the 100th paper 200 citations. The average number of citations was 320. Dates of publication ranged from 1953 - 2005. Most papers originated in the United States (n = 67) followed by Italy (n = 20) and France (n = 10). Harvard University (n = 18) and Osped Civile (n = 11) were the most prolific institutions. Ten journals produced all of the top 100 papers with “Radiology” and “AJR” making up the majority. SN Goldberg and T Livraghi were the most prolific authors. Nearly two thirds of the papers (n = 61) were published after 1990. CONCLUSION: This analysis identifies many of the landmark interventional radiology papers and provides a fascinating insight into the changing discourse within the field. It also identifies topics, authors and institutions which have impacted greatly on the specialty.
