Summary :
Objectives: We describe a case of an unusual remnant tooth located in the paranasal sinus in a head and neck cancer patient. Case report: A 72-year patient with a history of T3N2aM0 oropharyngeal cancer treated with chemoradiation came for systematic post-therapeutic multidetector-CT reformation (MDCT) examination. MDCT scan multi planar reformation revealed a well-limited high-density mass in his maxillary sinus, which proved to be a remnant molar tooth. Physical examination and CT imaging were performed at 26 months. Local malignancy, fungal ball and persistent oroantral fistula were ruled out. Conclusion: The physiopathogenesis of oroantral fistula (OAF) and causes of intra sinusal tooth as well as therapy are discussed in this article.
