Understanding sinonasal anatomic variations is crucial for functional endoscopic sinus surgery. Identifying these common variations on CT scans can prevent surgical complications and improve patient outcomes.
Area of Science:
- Otorhinolaryngology
- Medical Imaging
- Anatomy
Background:
- Functional endoscopic sinus surgery (FESS) advancements necessitate detailed sinonasal anatomy knowledge.
- Anatomic variations are prevalent in the population and frequently observed in CT scans.
- Variations can alter surgical landmarks, increasing complexity and complication risks in FESS.
Purpose of the Study:
- To emphasize the importance of recognizing sinonasal anatomic variations in CT imaging.
- To highlight the potential impact of these variations on surgical procedures and outcomes.
- To underscore the clinical significance of documenting variants, even when unrelated to the primary indication for imaging.
Main Methods:
- Review of CT imaging studies focusing on sinonasal anatomy.
- Analysis of the prevalence and types of sinonasal anatomic variations.
- Correlation of identified variations with potential surgical challenges and symptomatology.
Main Results:
- Sinonasal anatomic variations are common findings in CT practice.
- These variations pose challenges during endoscopic sinus surgery.
- Some variants are associated with specific clinical symptoms.
Conclusions:
- Comprehensive depiction of sinonasal anatomic variations in CT is essential.
- Awareness of these variants is vital for surgeons to mitigate risks.
- Accurate anatomical assessment aids in preventing surgical complications and managing patient symptoms.

Overview of the Skull
The cranial vault surrounds and protects the brain and houses the middle and inner ear structures. This cavity is bounded superiorly by the rounded top of the skull, which...
Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
