Summary
This study analyzed frontal sinus anatomy using CT scans. Frontal sinuses were generally larger in males, highlighting the importance of understanding variations for safe surgical approaches.
Area of Science:
- Neurosurgery
- Radiology
- Anatomy
Background:
- Minimally invasive surgical techniques are gaining prominence.
- The frontal sinus is frequently encountered during superciliary mini-craniotomy for parasellar region access.
Purpose of the Study:
- To assess the prevalence and morphological characteristics of the frontal sinus.
- To provide anatomical data relevant to neurosurgical procedures.
Main Methods:
- Computed tomography (CT) examinations were performed on 98 randomly selected individuals.
- Measurements included antero-posterior diameter, sagittal diameter, transverse diameter, and total volume of the frontal sinus.
Main Results:
- The frontal sinus dimensions, except for the transverse diameter, were generally larger in males compared to females (p < 0.10).
Conclusions:
- Understanding frontal sinus anatomical variations is crucial for neurosurgeons.
- Awareness of these variations can help prevent surgical complications like infections and cerebrospinal fluid (CSF) fistulas.
