Neck abscesses (collections of pus) can be located in either
a superficial (just under the skin) layer of the neck or deep
in the neck.
SUPERFICIAL NECK ABSCESS
What is a superficial neck abscess?
Superficial neck abscesses are usually the result of an infection
in a lymph node in the neck (lymphadenitis) turning into an abscess.
Please see LUMPS OR MASSES
IN THE NECK for additional information. The most common cause
of these abscesses are Staphylococcus or Streptococcus bacteria.
If the abscess will not resolve on antibiotics by mouth, the abscess
may need to be drained.
What is involved with drainage of a superficial
neck abscess?
Drainage of a superficial neck abscess is a relatively simple
procedure. It is performed under general anesthesia using a "mask"
to deliver the "sleepy air". Local anesthetic (numbing
medication) is injected into the area. The physician will then
feel the lump caused by the abscess to find the area most full
of pus. An incision (surgical cut) is then made to drain the pus
and a drain is inserted through the skin to keep the fluid from
collecting again.
The pus obtained is then cultured to determine the type of organism
causing the infection. A specific antibiotic can then be used
to treat the infection.
What are the complications of this procedure?
Complications of this procedure can include minor bleeding.
Certain abscesses should not be drained because of fistula (connection
to skin) formation. These types of abscesses are treated long
term with special antibiotics instead.
DEEP NECK ABSCESSES
Please see DEEP NECK
INFECTIONS for details on these types of infections.
What is involved with drainage of a deep neck
abscess?
The most important factor when draining any deep neck abscess
is to make sure that the airway is not obstructed. Therefore,
these procedures are always undertaken in a hospital setting where
emergency airway management is available.
Deep neck abscesses can be drained through the mouth (orally)
or through the neck (transcervically).
The oral (through the mouth) drainage procedure is used for
peritonsillar space abscesses and for specific cases of retropharyngeal
space abscesses. All other deep neck space abscesses are usually
approached through a surgical cut in the neck.
ORAL APPROACH OF NECK ABSCESS DRAINAGE
What is involved with the oral (through the
mouth) approach of peritonsillar abscess drainage?
As with any deep abscess drainage, an adequate airway must first
be secured. Most cases of peritonsillar abscesses are identified
before the airway is obstructed; therefore, breathing tubes are
usually not needed.
In younger children, the oral abscess drainage procedure is performed
under general anesthesia in hospital setting.
In older children and adults, an anesthetic (numbing) spray
is sprayed around the affected area in the back of the throat.
This is usually done in the hospital, but in some less severe
cases may be done in an office setting. A local anesthetic is
then injected around the area that is to be drained. A needle
is then placed in the bulging area in the back of the throat,
and the pus contained in the abscess is drained out. Complete
drainage may require placing the needle in more than one area
of the bulge or using a scalpel (knife) to open the abscess. The
material drained from the abscess is usually sent for bacterial
culture to make sure the correct antibiotic will be used. This
procedure usually lasts about 1/2 hour.
After this procedure, the patient usually feels much better and
can swallow more easily. Antibiotics are usually given for another
three weeks.
Cases in which the peritonsillar abscess recurs may require,
a TONSILLECTOMY.
What are the complications of the oral drainage
technique?
Local bleeding at the surgical site is the most common complication.
Although pus will sometimes continue to drain down the throat,
this rarely results in any other problem except nausea. Because
this abscess occurs near big blood vessels, your physician will
take precautions not to puncture too deeply causing damage to
the blood vessels.
SURGICAL CUT THROUGH THE NECK (TRANSCERVICAL) APPROACH
What is involved in the transcervical approach
for deep neck abscess drainage?
The patient is placed under general anesthesia for this procedure.
A surgical cut is made in the neck, and the abscess is located
and drained. The drainage is then for a bacterial culture. A drain
is usually left in the neck so the abscess does not return. The
length of this procedure varies with the size and complexity of
the location of the deep neck abscess.
Usually, the patient will continue on IV (in the vein) antibiotics
in the hospital to ensure complete resolution of the infection.
Once the drain is removed and the infection is resolving, the
patient may be sent home from the hospital on antibiotics by mouth.
What are the complications of this procedure?
The most common complications are bleeding, reaccumulation of
the abscess and damage to nerves. The most common nerve at risk
is the marginal mandibular nerve which moves the muscles around
the mouth. Special care is taken to protect this nerve during
these procedures.
Injury to other vital structures in the neck is also a possibility,
although uncommon with an experienced surgeon.
