Densitometric analysis of the paranasal sinuses

Area of Science:

• Anatomical studies
• Surgical anatomy
• Medical imaging

Background:

• Precise anatomical knowledge of the skull is vital for safe endonasal surgical procedures.
• Identifying critical weak points in the osseous skull structure is essential for surgical planning.

Purpose of the Study:

• To accurately describe the anatomy of the skull using serial sections.
• To evaluate the structure and density of paranasal sinuses and related areas using advanced imaging techniques.
• To provide qualitative and quantitative data on the frontobasal area, ethmoid cells, and sphenoid sinus.

Main Methods:

• Creation of serial skull sections with 1.5 mm thickness.
• Evaluation of sections using a computerized image analyzing system.
• Densitometric and gross anatomical techniques for sphenoid sinus analysis.

Main Results:

• Detailed qualitative and quantitative analysis of paranasal sinus anatomy.
• Specific data on bone density in the frontobasal skull area and ethmoid cells.
• Comprehensive anatomical description of the sphenoid sinus.

Conclusions:

• Computerized analysis of serial skull sections provides valuable insights into paranasal sinus anatomy.
• This detailed anatomical and densitometric data is crucial for improving the safety and efficacy of endonasal operations.
• The study highlights the importance of understanding skull base anatomy for surgical interventions.
