Biomaterials for use in frontal sinus obliteration

Area of Science:

• Neurosurgery
• Plastic Surgery
• Otolaryngology

Background:

• Frontal sinus fractures are uncommon but can have severe consequences due to their anatomical location near the brain and eyes.
• Management of nasofrontal duct or posterior wall injuries often necessitates frontal sinus obliteration.
• Despite a long history of surgical intervention, optimal obliteration materials remain debated.

Purpose of the Study:

• To review and compare autogenous and alloplastic materials used for frontal sinus obliteration.
• To assess the physical properties, benefits, drawbacks, and complications associated with various obliteration materials.
• To provide insights into the current landscape of materials for frontal sinus reconstruction.

Main Methods:

• Literature review focusing on autogenous and alloplastic materials for frontal sinus obliteration.
• Analysis of physical characteristics, clinical outcomes, and complication rates.
• Comparative assessment of historical and novel obliteration techniques.

Main Results:

• Autogenous fat is the most frequently used and historically significant material for frontal sinus obliteration.
• Several alloplastic materials demonstrate potential for effective frontal sinus obliteration.
• No definitive consensus has been reached on the single best obliteration material.

Conclusions:

• Autogenous fat remains a popular, reliable, and versatile choice for frontal sinus obliteration.
• Ongoing research into alloplastic materials may offer promising alternatives.
• Material selection for frontal sinus obliteration requires careful consideration of patient factors and material properties.
