The nasal: paranasal block technique. Preparation and uses

Area of Science:

• Anatomy
• Surgical Pathology
• Forensic Medicine

Background:

• Autopsy procedures traditionally involve head dissection, potentially causing disfigurement.
• Nasal and paranasal cavities are critical for understanding respiratory and neurological conditions.
• Current methods may not adequately preserve these delicate structures for detailed study.

Purpose of the Study:

• To introduce a new, minimally invasive autopsy technique for nasal and paranasal cavity removal.
• To demonstrate the preservation of anatomical integrity for educational and research purposes.
• To highlight the technique's utility in forensic pathology and surgical training.

Main Methods:

• A step-by-step description of the novel dissection technique.
• Emphasis on preserving the external facial structures.
• Post-dissection assessment of anatomical preservation.

Main Results:

• Successful removal of nasal and paranasal cavities without compromising the head's external appearance.
• Detailed visualization of the removed cavities for examination.
• Demonstration of the technique's applicability after brain removal.

Conclusions:

• The described technique offers a valuable method for anatomical study of the nasal and paranasal regions at autopsy.
• It facilitates enhanced training for endoscopic sinus surgery and histopathological analysis.
• Preserves the head's aesthetic integrity, crucial for certain forensic and educational contexts.
