Odontogenic Sinusitis – Case Report

Abstract

This case report aims to highlight the diagnostic and therapeutic approach for odontogenic sinusitis resulting from dental extraction. Odontogenic sinusitis is an inflammatory condition of the paranasal sinuses caused by dental disorders such as periapical infections, iatrogenic perforations, and maxillary fractures. It accounts for up to 30-40% of cases of chronic maxillary sinusitis. However, many cases are misdiagnosed, underscoring the importance of correctly identifying the cause to avoid inappropriate treatments. This case emphasizes the importance of an accurate diagnosis and multidisciplinary treatment in the management of odontogenic sinusitis. From the identification of odontological infectious disorders, mainly of the upper molars and premolars, to meticulous surgical, endodontic, and implant planning. An important factor in the diagnosis of acute odontogenic sinusitis is recent tooth extraction or implants where clinical bucco-sinusal communication or pain is observed in the first days after the procedure. Early identification and appropriate intervention are essential to prevent additional complications and ensure full recovery. The findings advocate for meticulous postoperative follow-up and the need for integrated care involving specialists in dentistry and otolaryngology.
