“…It is also possible that patients with CT scans showing no or minimal evidence of sinus inflammation may have had significant sinusitis on previous CT scans that improved or resolved even though they continued to experience sinusitis symptoms. 6 To minimize such problems in the present study, the chronic sinusitis patients were given a course of antibiotics antihistaminics and nasal decongestants just before the CT scan study.…”

“…Other studies have found wide variation (2-83%) in occurrence of agger nasi. [4][5][6]8 Studies demonstrate that their major dimensions are correlated with frontal sinus diseases and lacrimation. 7 All the subjects in the study had discharge in the frontal sinus.…”

“…5,6,8,10 Shift of the nasal septum away from the midline is usually associated with deformity or asymmetry of the adjacent turbinates or of the nasal wall structures, with variable presentation. Deviation of nasal septum can decrease the critical area of the osteomeatal unit predisposing to obstruction and related complications.…”

“…There is a strong consensus that knowledge of sinonasal anatomy and its variations is essential for safe and effective FESS or other skull base surgeries. 1,6 The presence of sphenoethmoidal (Onodi) cells is associated with increased risk of injuring the optic nerves or carotid arteries during FESS and with other transsphenoidal and skull base procedures. 17,18,19 To avoid accidental injury to the carotid artery and optic nerves, it is important to be aware of the midline of a highly pneumatized sphenoid sinus when opening the sella via a transsphenoidal approach.…”

Background: Variations in sinonasal anatomy of adults are common and vary among different populations. Their role in development of pathological conditions such as sinusitis, epistaxis, etc is debated. Having clear picture of sinonasal anatomy of a person is essential in avoidance of complications during surgery. This study was done to analyze sinonasal anatomy in adults from Karaikal region having chronic sinusitis by nasal endoscopy and CT scan imaging.Methods: A total of 50 patients undergoing endoscopic sinus surgery were studied by preoperative nasal endoscopy, CT scanning and endoscopy at the time of definitive surgery and variations recorded and analyzed. Results: The incidence of the sinonasal anatomical variations in CT scan study were – discharge in the frontal sinus (100%), agger nasi cells (96%), deviated nasal septum (70%), anterior ethmoidal cells (86%), posterior ethmoidal cells (58%), sinus lateralis (52%), frontal cells (50%), discharge in sphenoid sinus (50%), pneumatised superior turbinate (46%), INSA (34%), prominent bulla ethmoidalis (30%), supra orbital cells (26%), pneumatised septum(16%), medialised uncinate process (16%), paradoxical middle turbinate (16%), Haller cells (14%), supreme turbinate (14%), pneumatised inferior turbinate (12%), frontal recess obliteration (12%), absent pneumatisation of frontal sinus (12%), pneumatised middle turbinate (10%), Onodi cells (6%), pneumatised uncinate process (2%), maxillary sinus septation (2%).Conclusions: The high incidence of variations emphasises the need for proper preoperative assessment for safe and effective endoscopic sinus surgery.

I. Executive Summary Background The 5 years since the publication of the first International Consensus Statement on Allergy and Rhinology: Rhinosinusitis (ICAR‐RS) has witnessed foundational progress in our understanding and treatment of rhinologic disease. These advances are reflected within the more than 40 new topics covered within the ICAR‐RS‐2021 as well as updates to the original 140 topics. This executive summary consolidates the evidence‐based findings of the document. Methods ICAR‐RS presents over 180 topics in the forms of evidence‐based reviews with recommendations (EBRRs), evidence‐based reviews, and literature reviews. The highest grade structured recommendations of the EBRR sections are summarized in this executive summary. Results ICAR‐RS‐2021 covers 22 topics regarding the medical management of RS, which are grade A/B and are presented in the executive summary. Additionally, 4 topics regarding the surgical management of RS are grade A/B and are presented in the executive summary. Finally, a comprehensive evidence‐based management algorithm is provided. Conclusion This ICAR‐RS‐2021 executive summary provides a compilation of the evidence‐based recommendations for medical and surgical treatment of the most common forms of RS.

CT of Anatomic Variants of the Paranasal Sinuses and Nasal Cavity: Poor Correlation With Radiologically Significant Rhinosinusitis but Importance in Surgical Planning

Abstract: Analysis of every routine CT scan of the paranasal sinuses obtained for sinusitis or rhinitis for the presence of different anatomic variants is of questionable value unless surgery is planned.
