Abstract
Purpose
The greater palatine artery (GPA) is one of the main vessels supplying the nasal septum. We recently described a novel technique to reconstruct a nasal septal perforation (NSP) using a GPA flap. This radiological study explores the feasibility and limits of using a GPA flap for an anterior NSP repair.
Methods
We describe our technique for repairing anterior-most NSP. Radiological measurements of the GPA flap and their limits were analysed. Additionally, a cohort of four patients who underwent reconstruction of a NSP with a GPA flap was included.
Results
The radiological study of 150 nasal cavities showed a 31.5 ± 2.7 cm2 maximum flap area. Taking into account the retraction process (30%), the remaining area was 22.0 ± 1.9 cm2. The septal area anterior to the GPA was 6.1 ± 2.1 cm2. The septal portion of the flap was larger than the area anterior to the GPA pedicle in all cases. Complete NSP repair was achieved in four patients. All cases of NSP remained closed during the follow-up.
Conclusion
The unilateral GPA pedicled flap is a useful technique suitable for the reconstruction of anterior-most perforations that are difficult to cover with other endonasal techniques.
