title: Concha nasoturbinalis in human adult?
abstract: In a macerated skull from a 20 year-old body we found, bilaterally, a variation corresponding to the nasoturbinal concha of quadrupeds. According to the data in the literature, the remnants of this concha may be named either "agger nasi" or "agger cell". These formations may impede the approach to the frontal sinus or the lacrimal sac, respectively. A nasoturbinal concha is extremely rare in adults and should be considered when approaching the frontal sinus.
