Anterior Buttress in ENT Surgery
I must clarify that the term "anterior buttress" does not appear to be standard ENT terminology based on the available evidence. The provided literature primarily discusses buttresses in maxillofacial reconstruction, orbital surgery, and airway reconstruction—not routine ENT procedures.
What the Evidence Actually Shows
Buttress Concepts in Head and Neck Surgery
In maxillofacial reconstruction, buttresses refer to supportive bony structures of the facial skeleton that form thick, strong, protective frameworks 1. The key facial buttresses include:
- Zygomaticomaxillary buttress (ZMB): Essential for preventing eyeglobe malposition when orbital contents are preserved and provides good malar prominence contour 2
- Pterygomaxillary buttress (PMB): Provides support for dental prosthesis fitting 2
- Nasomaxillary buttress (NMB): Prevents superior and posterior deviation of the alar base and oral commissure 2
Buttress Applications in ENT-Adjacent Procedures
For airway reconstruction, various materials serve as anastomotic buttresses to reduce complications 3:
- Mediastinal pleural flap (most common at 38.7%)
- Anterior cervical muscle (22.6%)
- Thymus flap (19.4%)
- Sternocleidomastoid, intercostal muscle, biological patches, and other tissues 3
For skull base repair after endoscopic pituitary surgery, biodegradable plates (PolyMax RAPID) can serve as rigid buttresses to reconstruct the sellar floor and support the pituitary gland 4.
Common Pitfall
The term "anterior buttress" is not standard ENT nomenclature. If you encountered this term in a specific clinical context, it may refer to:
- Anterior nasal support structures in rhinoplasty
- Anterior maxillary buttress in facial trauma
- Anterior skull base support in endoscopic procedures
The rhinoplasty literature discusses spreader grafts, batten grafts, and strut grafts for nasal support 5, but these are not typically called "anterior buttresses."
What to Do Clinically
If you need clarification on "anterior buttress" in a specific ENT context, request anatomic specification from the referring source, as this terminology is not standardized in ENT literature and could lead to miscommunication about surgical planning or anatomic assessment.
