Introduction
Auricular seroma is a cystic swelling with a collection of serous fluid between the perichondrium and cartilage. It is usually in the upper part of the auricle. Seromas can develop spontaneously or after surgery or trauma (primarily blunt trauma) to the ear. An amber or straw-colored fluid is sometimes aspirated. Depending on the nature of the swelling and symptoms, auricular seromas can be distinguished from other lesions of the pinna. Successful treatment of auricular seromas is challenging because of their high propensity for recurrence. We propose a very simple, effective management of seromas by remodeling a corrugated rubber drain.
Methods
Between May 2010 and August 2013, we treated 20 cases of auricular
seromas at the Mahatma Gandhi Institute of Medical Sciences (Sevagram,
India). No patient had any history of insect bites or any other medical
illness. One patient had a definite history of blunt trauma to the ear;
it was a nontender fluctuant swelling.
All seromas were drained by aspiration using all aseptic precautions [Figure 1].
The corrugated rubber drain was cut and shaped in accordance with the
site of the seroma. Using 3-0 silk, the remodeled piece of corrugated
rubber drain was fixed through the cartilage using a single suture [Figure 2].
Antibiotic ointment was topically applied, but no dressing was applied.
The patient was administered with oral antibiotics and oral
anti-inflammatory drugs. After 3 days, the patients were reviewed and
the splint was removed. For the next 7 days, the patients were
followed-up for any recurrence.
Results
Of the 20 patients, 18 patients were males and 2 patients were females.
Thirteen patients had swelling in the right ear and seven patients had
swelling in the left ear. The mean age of the patients at presentation
was 23.9 years. The most common complaint was external deformity,
followed by pain (2 patients). [Table 1] lists the sites of the seromas.
Of
the 20 patients, 2 patients had already been treated with aspiration
and bandage, but they presented with recollection. The exact cause of
the seromas was unknown, except for 1 patient in whom there was a
definite history of blunt trauma to the ear while playing.
All patients tolerated the procedure well. They were followed-up every 7 days up to 21 days. After 3 days, the splint was removed. None of the patients had any collection of fluid or experienced any pain, fever, or edema. The seroma disappeared without disfigurement. Further follow-up showed no recurrences. The patients were reviewed subjectively for the cosmetic impact of the treatment. We found that they were satisfied with the treatment since there were no dressings, which prevented social embarrassment. It was cosmetically acceptable [Figure 3].
Discussion
The successful treatment of auricular seromas remains a challenge because this
disease has a high propensity for recurrence. Seromas are usually drained by
aspiration and a compression bandage is applied. It is difficult to maintain
molded pressure bandages on both sides of the pinna in place long enough to
effectively prevent recollection. Many patients have a recollection and the
bandage causes social embarrassment. Ghanem et al. found
recurrence of seromas after aspiration and bandage. Various other treatment
modalities have been practiced such as applying pressure splints using coat
buttons, achieving compression using cotton wool bolsters, and using silicone
rubber splints. The limitations of these modalities include their availability
and pliability. O'Donnell and Eliezri suggest excising a disc of cartilage and
perichondrium to cure recurrent seromas. Placement of a continuous portable
suction drain that remains at the incision site is a treatment option that has
been advocated. Mattress or quilting sutures are applied in anatomical grooves
to achieve compression more evenly after primary aspiration. The intralesional
injection of triamcinolone as a treatment option for auricular seromas has also
proven useful. A review of the literature suggests that 19-gauze stainless
steel wire and chemically cured resin have been used to fabricate a pressure
appliance to prevent recurrence.
We have proposed a very simple and
effective management of seromas using aspiration and applying a splint formed by
remodeling a corrugated rubber drain. A corrugated rubber drain has many
advantages. A corrugated rubber drain is firm and easily available. It can be
remodeled so that it fits into the small depressions of the pinna. It is pliable
and can be shaped in accordance with the site of the seroma. This drain is fixed
with a single suture, which splints adequately. No dressings are required and no
complications have been noticed. This method is a minimally invasive procedure
that is simple and effective. It also prevents patient distress from
recollection, treatment, and social embarrassment. It is also cost-effective.
This treatment can be administered to large seromas by using a single suture. A
corrugated rubber drain is a treatment option in a rural setting where the
availability of resources limits the treatment options. Most patients prefer not
to make repeated visits to an outpatient department. This type of treatment is
simple and effective. To prevent auricular cartilage infections, it has been
suggested that seromas should not be aspirated in an outpatient department.
However, our simple procedure can be performed with no complications in an
out-patient department, provided it is performed under aseptic conditions and
precautions are maintained.
