Abstract

The present report describes the case of a patient who underwent maxillary sinusitis right after dental implant installation with sinus lifting. Computed tomography scan revealed a dental implant (#16) was protruded inside the right maxillary sinus and confirmed the obstruction of ostium. A symptom remission was gained with the dual approaches combined by functional endoscopic sinus surgery and an intra-oral approach. Fully recovered function and healing of sinus were identified after 10 months follow-up. We report the case of sinusitis caused by protrusion of implants with sinus floor lift procedures and propose that practitioners should be aware of the possible its complications and management.

Figure

• 

  Fig. 1 Panoramic view taken 5 days after right maxilla sinus bone grafting and #16 implantation revealed dental implant protrusion into the right maxillary sinus.

• 

  Fig. 2 Paranasal sinuses computed tomography revealed mucosal thickening and opacification with air bubbles in the right maxillary sinus and the protrusion of an implant fixture into the sinus, along with a bony fragment (arrow).

• 

  Fig. 3 Water's view computed tomography revealed increased density and haziness in the right maxillary sinus.

• 

  Fig. 4 Endoscopic view, after uncenectomy and maxillary sinus ostium enlargement.

• 

  Fig. 5 An intra-oral approach allowed for the removal of the mobile dental implant and closure of the oro-antra fistula.

• 

  Fig. 6 Computed tomography revealed that opacification of the right maxillary sinus was decreased 1 week postoperatively. Mucosal thickening of the sinus wall had also decreased.

• 

  Fig. 7 Transverse dental computed tomography scanning revealed complete recovery of the right maxillary sinus with normal mucosal thickness 10 months after surgery.
