What is the procedure for making an incision into the sinus called?

The procedure for making an incision into the sinus is called a sinusotomy. This surgical technique involves creating an opening in one of the sinuses, typically to facilitate drainage, obtain samples for biopsy, or allow for the removal of obstructions or diseased tissue. Sinusotomy is commonly performed in cases of chronic sinusitis or other sinus-related conditions that do not respond to medication.

Other options refer to different procedures: sinusectomy involves the surgical removal of sinus tissue, which is not the same as making an incision; sinus aspiration typically refers to the process of extracting fluid or pus from the sinus using a needle or suction, rather than making an incision; and sinoscopy involves visual examination of the sinus using an endoscope, which does not include making an incision. Thus, sinusotomy is the precise term for the specific action of incising the sinus.
