Bone suture and lateral sinus lift surgery

Area of Science:

• Oral and Maxillofacial Surgery
• Regenerative Dentistry
• Anatomical Reconstruction

Background:

• Lateral sinus lifts are crucial for maxillary augmentation.
• Schneiderian membrane perforation is a complication during sinus lifts.
• Buccal fat pad (BFP) has been utilized for graft support and membrane fixation.

Purpose of the Study:

• To detail four indications for bone suture in lateral sinus lifts.
• To present a new application of the buccal fat pad (BFP) in managing perforated Schneiderian membranes.
• To highlight the BFP's role as a last resort for securing the membrane.

Main Methods:

• Review of existing literature on sinus lift techniques and BFP utilization.
• Description of the surgical technique for anchoring the BFP to the medial maxillary sinus wall.
• Analysis of the BFP's role in managing perforated Schneiderian membranes.

Main Results:

• Established three indications for bone suture involving membrane fixation via a lateral wall opening.
• Previously reported uses of BFP for graft nourishment and membrane fixation.
• Demonstrated a new indication: anchoring BFP to the medial sinus wall for perforated membrane management.

Conclusions:

• Bone suture offers versatile solutions for sinus membrane management.
• The buccal fat pad (BFP) provides a valuable option for graft support and perforation repair.
• Anchoring the BFP to the medial sinus wall represents a novel, effective last resort for complex membrane perforations.
