Remnants of ossicula Bertini in their embryological position, i.e., jo
ined to the ethmoid, were found in three out of 20 adult individuals a
ged 17-23 years. The ossicles closed the inferior and/or a part of the
anterior wall of the sphenoidal sinus, being joined to the wall of th
e sinus by sutures. The existence of these formations might be of impo
rtance in inflammation of the sphenoid sinus, or disease in or around
the nasopharynx.
