Dual antrostomy optical window for visualising sinus cavity during implant restoration
Summary
The authors report a case of maxillary sinusitis that developed after placement of four dental implants. Although one implant failed due to infection, the remaining dental implants were functional. A polyp had been identified on CT scan before implantation. Discussion of the possible odontogenic aetiology of the maxillary sinusitis led to consideration of explantation. Both middle and inferior meatal antrostomy were performed for utilisation as optical windows during postoperative care, allowing direct visualisation of the sinus cavity. The characteristics of the nasal mucosa were evaluated during a series of dental treatments including implant removal, sinus floor elevation and re-implantation.
