This study reveals specific anatomic information that is applicable to the technique of transnasal maxillary sinus balloon catheter dilation.
The data collected allow surgeons to anticipate the direction in which a guidewire must be manipulated in order to correctly enter the maxillary ostium.
According to the data, a gentle anterior retraction of the uncinate process and a starting guide orientation 180 from pure lateral will best facilitate maxillary sinus ostial access.
Application of the readily available software used for this study affords the opportunity to predict the location of the natural ostium within the infundibulum before operation and customize the technique to each specific patient.
