Surgical Treatment
Early drainage interrupts the pathologic process and prevents complications .
# Myringotomy
Myringotomy permits drainage of the mastoid if the aditus ad antrum is not blocked. Tympanostomy tubes permit drainage over a longer duration. Postoperatively,antibiotic/steroid drops are used to keep the tube patent and to reduce middle ear swelling. Antibiotic/steroid drops are continued until the otorrhea ceases.
# Mastoidectomy
Mastoidectomy is performed to remove the mastoid infection,open the aditus ad antrum,and provide external drainage. Indications for mastoidectomy may include:
Computed tomography evidence of coalescent mastoiditis (regardless of other clinical features)
Subperiosteal abscess
Other suppurative complications of acute mastoiditis
Progression or persistence of fever,ear pain,postauricular swelling,or drainage despite parenteral antimicrobial therapy and tympanocentesis/myringotomy","department":"
