Naso-oral fistula due to rhinolithiasis: a rare presentation.

Abstract

Naso-oral fistula, as the name suggests, is an abnormal communication between the nasal and oral cavities. It is an extremely rare clinical entity encountered in routine rhinology clinics across the world. The occurrence of this fistula due to rhinolithiasis is much rarer. We present one such case in a 40-year-old man, who came to us for assessment of a "hole" in his palate. The cause of this naso-oral fistula was found to be a rhinolith in the right nasal cavity. This report emphasizes that trainee rhinologists should be vigilant about this little recognized and rare condition.
