Ectopic Deciduous Maxillary Tooth in the Nasal Cavity Following Trauma

Abstract

Several cases of the ectopic supernumerary tooth in the nasal cavity have been reported; however, an eruption of the primary maxillary tooth in the nose following trauma is extremely rare. Clinical evaluation and discriminating features on CT imaging, particularly with bone window setting, are sufficient to confirm the diagnosis. We discuss a case of deciduous central maxillary incisor in the nasal cavity and specifically focus on its clinical and radiological presentation. None of the previous authors have discussed probable theories of the post-traumatic intranasal tooth; we consider two possible theories which might be responsible for the ectopic intranasal tooth after trauma. Additionally, we discuss pertinent features which help distinguish ectopic deciduous tooth from the supernumerary tooth.

An Intranasal Ectopic Tooth in an Adult

“…Surgery is the main treatment option aimed to alleviate symptoms and prevent complications, such as osteomyelitis, nasal septal abscess or perforation, rhinosinusitis, dacryocystitis, oronasal or intraoral fistula, aspergillosis, and nasal deformity [ 4 , 7 ]. The surgeon may suggest either an endoscopic endonasal, a conventional endonasal, or a transoral approach depending on their experience in the endoscopic nasal surgery, patient’s age, presence of a bony socket, and depth of eruption [ 12 ]. As with our patient, after multiple consultations with an oral surgeon and otorhinolaryngologist with regard to surgical extraction, the intraoral approach was dismissed and the endoscopic removal of the tooth was chosen as the most conservative surgical method.…”

Endoscopic Surgical Excision of Ectopic Tooth in Left Nasal Cavity

“…As in this patient’s case, the tooth’s presence likely resulted in nasal malodor, crusting, and discharge. Other patients have been reported to suffer from chronic nasal obstruction and congestion, facial pain, purulent or blood-tinged rhinorrhea, recurrent epistaxis, rhinitis caseosa, and fungal ball development [ 1 - 7 ].…”
