used in mastoid surgeries like mastoidectomy: Rose's sinus washing canula: to irrigate the maxillary sinuses: Higginson's syringe: irrigating the antrum,nasal douching for atrophic rhinitis Ballenger's swivel knife: cutting septal cartilage; SMR operation Nasal foreign body hook: to remove nasal foreign bodies Electric drill: for bone drilling
The tube is extruded spontaneously after a few weeks to months, and the incision heals naturally. If there are complications, or the mastoiditis does not respond to the above treatments, it may be necessary to perform a mastoidectomy: a procedure in which a portion of the bone is removed and the infection drained.
