Ectopic supernumerary tooth on the inferior nasal concha

Variations regarding the location of an ectopic tooth in the human nasal cavity, although rare, are documented in the literature, but presence of an ectopic tooth on the inferior nasal concha (INC) has not been reported. We observed an anomalous tooth projecting from the posterior margin of the right INC in two adult female skulls. A small quadrangular tooth projected beyond the posterior margin of the hard palate in one of the skulls and a medium sized conical tooth was observed in the other skull. The affected INC in both skulls were located more inferiorly compared to the opposite side and were in close approximation with the hard palate. No similar findings were noted on the contralateral side nor were there any associated congenital or iatrogenic deformity. The phylogenetic, ontogenetic, and clinical importance of this variant is described. Knowledge of such an anomaly is of paramount importance to otorhinolaryngologists, reconstructive and dental surgeons, and radiologists for identification of such rarities encountered during invasive or non-invasive procedures.
