This article presents a case report of an adult patient with chronic sinusitis related to the presence of two erupted ectopic teeth located atypically in the maxillary sinus roof/orbital floor after a long latency period associated with childhood facial trauma. This article aims to show the treatment of chronic sinusitis of odontogenic origin by surgical removal of ectopic teeth in an unusual position by direct visualization. This case report discusses the signs and symptoms of chronic sinusitis linked to the presence of ectopic elements and associated with an inflammatory cyst, the choice of complementary tests for diagnosis and surgical treatment through the Caldwell-Luc procedure. After a 2-year follow-up period, the patient presently shows clinical improvement, thus demonstrating the success of the chosen treatment.
