(8) The ear dressing is applied, including a shaped ear pad. Fluffed 4 x 8
inch gauze sponges are placed around and behind the affected ear and then flat
compresses over the affected ear. A gauze bandage is applied in a particular manner
to hold the dressings in place and avoid pressure.
1-25. SIMPLE MASTOIDECTOMY
a. General. Simple mastoidectomy involves the removal of the air cells of the
mastoid process without disturbing the contents of the middle ear. It may be done
occasionally to treat acute empyema (accumulation of pus) of the mastoid, but has been
made almost obsolete by antibiotics.
b. Operative Procedure. A postural or endaural incision is made. Perform
procedures for a radical mastoidectomy as stated in paragraphs 1-24c(1), (2), (3), and
A modified radical mastoidectomy may also be done in which the middle ear
is not involved, but in which the thin bridge of bone between the external
canal wall and antrum is removed.
1-26. TYMPANOPLASTY OPERATIONS
Tympanoplasty involves a large variety of reconstructive operations of the middle
ear designed to restore or improve hearing in patients with middle ear or
conductive-type hearing loss. In various operations of this type, tissue grafts of different
kinds are often used.
Section III. NOSE SURGERY
1-27. OPERATIONS ON THE NOSE
Operations on or through the nose (see figure 1-8) may be required to correct
results of trauma to the nose and related structures; to correct deformities that interfere
with breathing, such as deviated nasal septum, hypertrophy of the turbinates, and
polyps or other neoplasms; and to relieve the effects of sinusitis.
1-28. ANATOMY AND PHYSIOLOGY OF THE NOSE
The nose is divided into the prominent external nose and the internal nose known
as the nasal cavity. The chief purpose of the nose is the preparation of air for use in the
