Nasopalatine Island Advancement Flap

Area of Science:

• Oral and Maxillofacial Surgery
• Periodontology
• Dental Implantology

Background:

• The anterior maxilla is crucial for facial esthetics.
• Current bone graft coverage techniques often rely on secondary epithelization.
• A novel mucoperiosteal flap is evaluated for improved coverage in this region.

Purpose of the Study:

• To assess the versatility and reproducibility of a new mucoperiosteal flap for anterior maxillary reconstruction.
• To evaluate the efficacy of the nasopalatine island advancement flap in a defect model.

Main Methods:

• A 5mm labial mucosal defect was created in the anterior maxilla of 5 mongrel dogs post-incisor extraction.
• The nasopalatine island advancement flap was utilized for mucosal defect closure.

Main Results:

• The nasopalatine island advancement flap demonstrated complete survival.
• Healing occurred without any signs of flap necrosis.
• The flap provided successful coverage of the created defect.

Conclusions:

• The nasopalatine island advancement flap is a dependable axial island flap.
• This technique is suitable for anterior maxillary reconstruction.
• The flap offers a reliable solution for mucosal coverage in the anterior maxilla.
