The Bony Window Technique as a mini-invasive surgery to retrieve foreign bodies in the maxillary sinus: A technical note

Abstract

The dislocation of foreign bodies in the maxillary sinus is not an unusual complication of dental treatments like tooth extraction, root canal treatment, maxillary sinus surgery, or dental implant installation, whose related significant risk is the onset of pathologies involving the maxillary sinus or all the paranasal sinuses. Many previous techniques have been proposed, including intraoral and endoscopic approaches to sinus surgery. However, their recommendation varies depending on the local and systemic factors that affect patients.

This article describes the ``Bony Window Technique,'' which has been demonstrated as a mini-invasive approach to retrieve foreign bodies in the maxillary sinus to treat mild odontogenic sinusitis and systemic complications, even in different pathologic conditions of the maxillary sinus.
