This case report describes an extraordinary case of the spontaneous transmaxillary-transnasal discharge of a dental implant, which occurred during a sneeze. The patient was complained of symptoms of acute sinusitis. She underwent a computed tomography scan that revealed a dental implant dislocated in the maxillary sinus. Medical treatment based on antibiotics and mucolytics was administered to the patient in order to prepare her for endoscopic endonasal surgery. The implant was spontaneously discharged two days after during a sneeze. Mucociliary clearance in combination with a local osteolytic inflammatory process and mucolytics therapy are the likely causes of this unusual discharge.
Core tip: Iatrogenic dislocation of dental implants into paranasal sinuses is not a rare pathological finding. Dental implants dislocation are commonly related to a wrong operating procedure or diagnostic clinical planning. Functional endoscopic sinus surgery has been widely described as the first option to remove foreign bodies from the paranasal sinuses, while the Caldwell-Luc approach to the maxillary sinuses still represents an option if the patients wants to avoid general anesthesia. Up-today just one case of spontaneous nasal discharge was reported in the literature. Therefore this case report describes a really uncommon clinical finding.
