Two cases of endoscopic endonasal sinus surgery for maxillary sinusitis due to dental implant treatment

Abstract

Reports of dental maxillary sinusitis as a complication associated with implant treatment are sporadic. As an initial response, we first try to calm the acute inflammation by dosing；however, the need to remove the implant body and bone filler in intractable cases has not yet been confirmed. We experienced two cases in which endoscopic nasal sinus surgery (ESS) was performed for maxillary sinusitis due to implant treatment. The common points of these two cases were inflammation causing narrowing of the root of the middle nasal passage and a high value of IgE, as well as positivity for multiple allergies. ESS and treatment for allergic rhinitis made it possible to heal the implant body while preserving the bone filler.
