Aims:
The aim of the present study is to evaluate the clinical applicability of laser energy during an oro-nasal endoscopic approach (ONEA) in the management of the anterior maxillary sinus wall.
Methods:
An experiment on three adult human cadavers was performed to study the nasal cavities with angled rigid scopes and using the ONEA technique. In order to evaluate the effectiveness of laser energy on the bone, the drilling effect was compared to laser energy (1470 nm diode laser, continuous wave, power 8, 9 and 10 W).
Results:
Compared to a rigid angled scope, the ONEA technique allowed complete visualization of the anterior wall of the maxillary sinus. Microscopic analysis of frontal bone revealed similar bone Exeresis with high-speed drilling (270.28 μm) and laser approaches (285.73-456.6 μm).
Conclusions:
The laser ONEA technique is an innovative, mini-invasive, and safe approach to the anterior wall of the maxillary sinus. Additional study is warranted to further develop this technique.
