Rare presence of foreign bodies in maxillary sinuses due to dental procedures; A retrospective case series analysis of treatment.

Displacement of foreign bodies into the maxillary sinuses during dental procedures is a rare entity. The most common causes are the iatrogenic dental procedures and the maxillofacial trauma respectively, according to the literature. The aim of this article is to present a case series of foreign bodies displacement into the maxillary sinuses due to iatrogenic dental procedures. Material and Methods Detection of the foreign bodies into the maxillary sinuses was achieved with radiologic methods and confirmed intraoperatively or later with the histopathology report. Minimal invasive procedure was the treatment of choice in all cases. Results Our study included 27 patients, 17 males and 10 females with mean age of 46.14 years (SD 10.35, range 18-65 years). The displacement of foreign bodies into the maxillary sinus concerned to fragments of teeth in 11 patients (40.27%), whole teeth in 4 (14.81%), dental implants in 5 (18.51%), dental impression materials in 2 (7.4%), endodontic treatment materials in 4 (14.80%) of which 2 associated with aspergillosis, fractured or not dental burs in 1 (3.7%). The occurrence of paranasal sinusitis due to foreign bodies displacement into the maxillary sinuses is time-dependent, the faster the treatment the better the outcome. Discussion Development of paranasal sinusitis due to displacement of foreign dental bodies into the maxillary sinuses is the physical outcome. Early surgical treatment is the key factor for to avoid sinusitis or minimize its occurrence.
