Micro and nanoparticle deposition in human nasal passage pre and post virtual maxillary sinus endoscopic surgery

Micro and nanoparticle deposition in human nasal passage pre and post virtual maxillary sinus endoscopic surgery

Highlights ► The maxillary sinus ventilation changes significantly after uncinectomy and MMA. ► Removal of the uncinate process and MMA increase the number of inhaled micro-particles into the maxillary sinus by 10-fold. ► The uncinectomy and MMA operation leads to a significant increase in the nano-...

Zusammenfassung:Highlights ► The maxillary sinus ventilation changes significantly after uncinectomy and MMA. ► Removal of the uncinate process and MMA increase the number of inhaled micro-particles into the maxillary sinus by 10-fold. ► The uncinectomy and MMA operation leads to a significant increase in the nano-particle deposition in the maxillary sinus.
