Ear, Nose, and Throat Disorders

What is a Haller cell?



I was recently diagnosed with a sinus osteoma and a small right-sided Haller cell. I am able to find sinus osteoma explained in many places. I am not able to find out what a Haller cell is. Can you explain it to me and what effects it might have on my sinuses?


"Haller cells" are ethmoid sinus air cells that extend out under the orbit (eye).  They are not that unusual, and unless they are infected or causing blockage or obstruction of the natural opening of the maxillary sinus, nothing needs to be done with them.
