Sizing done by 3-D printing for prosthetic closure of nasal septal perforations resulted in a higher retention rate in helping patients with these most-challenging nasal septal perforations.

Objective: To investigate the association of high septal deviation with the olfactory fossa depth and Gera angle. Methods: Fifty-four computed tomography scans of patients with high septal deviation were evaluated. The olfactory fossa depth and Gera angle were measured. The values of the deviated and nondeviated sides were compared. Results: No association between high septal deviation and the olfactory fossa depth and Gera angle was found. Conclusion: High septal deviation does not affect the olfactory fossa depth and Gera angle. In other words, the olfactory fossa depth and Gera angle have no association with the high septal deviation.

ObjectiveThis study was performed on fresh frozen cadavers to investigate the role of angular artery damage.MethodsLateral osteotomies (‘high-low-high’ method) were carried out bilaterally, with a 4 mm guarded lateral osteotome, after the creation of a subperiosteal tunnel. Following completion of the lateral osteotomy, a skin incision was made in the midline dorsum. The dermis and subcutaneous tissues were carefully dissected, taking care not to damage the angular artery. Overlying tissues were cut and retracted to show the course of the angular artery.ResultsThe angular artery was not damaged in any of the cadavers. The angular artery was always lateral to the lateral osteotomy line.ConclusionThe high-low-high lateral osteotomy does not damage or traumatise the angular artery. The ecchymosis and oedema are related to other factors.
