Traumatic injuries or surgical procedures in susceptible areas often lead to development of keloid due to complicated
wound healing. Keloids of ear lobe are a common complication of ear piercing, although its overall incidence is
unknown. Pressure therapy has been employed to treat pinna keloids. The main aim of this therapy is to maintain
constant pressure and duration of therapy is about twenty-five weeks. Pressure therapy has been widely used to help in
the early maturation of scar tissue and to prevent the recurrence of keloid. This article describes the fabrication of
custom made pressure clips which have been used for patients with auricular keloids. KEYWORDS: Custom made appliance, Keloids, Pressure clips, Pressure therapy

often been used to distinguish hypertrophic scars from
keloids. 1,2
Keloids extend beyond the margins of the original wound
which distinguishes them from hypertrophic scars which
stay within the confines of the injured area. Originating
from the Greek word ‘chele’ which means ‘crab claw’,
the term ‘cheloide’ was first used by Albert in 1806 to
describe the lateral expansion of an excessive scar into
the surrounding normal tissue.
Ear piercings are often followed by such complicated
wound healing process which firstly extends beyond the
original site and secondly does not show spontaneous
regression. These are the two key features differentiating
them from simple hypertrophic scars. This distinction is
difficult to discern clinically, but it is imperative to do so
as prognosis of hypertrophic scar is spontaneous
softening and flattening whereas keloids maintain their
thickness and remain elevated for years. Also it is more
difficult to achieve total excision and primary closure in
case of keloids as compared to hypertrophic scars.4,5
The best treatment strategy to avoid these complications
is prevention. Patients prone to excessive scar formation
should avoid surgical procedures until absolutely
essential, particularly in high risk locations susceptible to
development of keloids. Clinicians today are presented
with a plethora of treatment options to choose from for
the treatment of hypertrophic scars or keloids which
include radiotherapy, cryosurgery, intra-lesional cortico-
steroids, laser therapy, or a combination of these. All of
them have their own pros and cons and have shown
varying degrees of success. Unfortunately there is no
single treatment modality or a universally accepted
treatment protocol that can guarantee a complete and
permanent amelioration and also prevent recurrence.6
The search for a less aggressive and conservative
management option for scars lead to the development of
pressure therapy. Over the years it has been established as
an effective treatment option, to reduce the amount of
scar tissue. It works on the mechanism of application of
continuous pressure which creates localized hypoxia,
resulting in fibroblast degeneration and cell breakdown.
Constant pressure of 25 mm Hg for minimum six months
has been recommended by various authors. Care should

Management of keloids always remains is a challenge.
This article describes a case series of young female
patients with auricular keloid, for which simple, logical,
inexpensive therapeutic appliances were fabricated.
Further studies can be performed to evaluate the efficacy
of such appliances on the remission of auricular keloids.
The management of two patients who visited Department
Of Prosthodontics, V.S. Dental College & Hospital with
keloids in the ear pinna is described in this report where
pressure therapy was utilized. The aim was to provide a
conservative and economical treatment option to these
patients, who could not afford more expensive therapy

clips of auto polymerising polymethylmethacrylate were
fabricated which were esthetically acceptable to the
patients for management of keloids.

CASE REPORT Shastry T. et al.: Custom made Acrylic Therapeutic Pressure Appliance for Auricular Keloid
Case 1
A 32-year-old female patient was referred from the
Department of General Surgery, Kempegowda Institute
of Medical Sciences, Bangalore, Karnataka to the
Department of Prosthodontics, V.S. Dental College and
Hospital, Bangalore for the management of auricular
keloid. Figure 1
The Patient gave a history of infection in both the ears 6
months back which required an incision, surgical
debridement and placement of sutures. The wound healed
in a complicated manner resulting in the appearance of
tissue overgrowth at the site of wound closure 2 months
after removal of the sutures. The swelling increased in
size for the following 2 weeks and was accompanied by
severe pruritis and erythema. In the following weeks, the
pruritis and erythema subsided but the size of the
swelling remained constant.
On examination it revealed a small irregularly shaped
swelling on the superior aspect of the helix involving the
scaphoid fossa, extending 0.5 mm into the crura of
antihelix measuring 2.8 cm anteroposteriorly x 1.9 cm
superoinferiorly and 2.9 cm anteroposteriorly x 1.6 cm
superoinferiorly on the right and left ear respectively. The
skin covering the swelling had a tense and stretched
appearance. On palpation, it was found to be non-tender
and had a rubbery consistency. Figure 2
Case 2
A 30-year-old female patient was referred from the
Department of Surgery, Bowring hospital, Bangalore for
the management of auricular keloid. Figure 3
The chief complaint of the patient was swelling in the
helix of the right and left ears since one month. A history
of ear piercing was given by the patient on both right and
left ears 8 years back which was followed by the first
appearance of swellings bilaterally 3 years back along
with accompanying pain and itching. There was a gradual
increase in the size of the swellings in both the ears.
Swelling in the right ear was larger in size than the left
ear. Both the swellings were surgically excised one
month back.
On examination, a small, oval non-tender irregularly
surfaced swelling was present on the helix of the right &
left ear, measuring 1.8cm anteroposteriorly x 2cm
superoinferiorly and 1.7cm superoinferiorly x 1.2cm
anteroposteriorly respectively. Figure 4

CASE REPORT Shastry T. et al.: Custom made Acrylic Therapeutic Pressure Appliance for Auricular Keloid
There was no pain, itching or other accompanying
symptoms except that it caused emotional stress due to
impaired esthetics.
A clinical diagnosis of bilateral auricular keloid of the
helix was given for both cases. It was decided to use
pressure therapy to prevent recurrence of keloid on both
right and left ears. Custom made polymethylmethacrylate
passive pressure appliances were planned to be used for
maintaining the pressure for a specific period of time and
to prevent the recurrence in both ears.
Procedure followed for fabrication of passive pressure
appliance: The skin over the right and left ear was
lubricated with petroleum jelly, and the external auditory
meatus was blocked using cotton. Primary impressions
were recorded using a thin mix of irreversible
hydrocolloid impression material (neo colloid tm
,
Zhermack) with the patients’ head tilted to the opposite
side for which impression was being made. The
impression material was loaded into a syringe and
injected over the desired area to ensure recording of the
fine details of the defect. A thin mix of plaster of Paris
was poured over the irreversible hydrocolloid as a
backing, material. Figure 5
Completed impressions were retrieved, and disinfected
following which the impressions were cast in dental stone
and master casts of both ears were obtained. Figure 6 (A)
& (B)
A spring was designed using 8mm diameter stainless
steel wire that was made as a V- shaped loop with a helix
at its apex and adapted over the region of the keloid.
Figure 7
A final trial was done on the patient to make sure of the
fit and extent of the pressure clip to ensure coverage of
the desired area and adjustments were made in the helix
avoidance of excess pressure and ensure comfort for the
patients. Figure 8
Custom made pressure appliances were fabricated
incorporating this loop in clear polymethylmethacrylate
resin (DPI RR Cold cure-clear, DPI, Mumbai, India) and
characterization was done using fabric paints and
artificial ornamental stones to make it resemble auricular
ornament thereby making the appliance more esthetically
acceptable to the patient. Figure 9 A & B
All sharp projections were removed using acrylic
trimming bur and the appliances were finished and
polished. Finally, a clear coat was applied to preserve the
integrity of the characterization. Figure 10 & 11

CASE REPORT Shastry T. et al.: Custom made Acrylic Therapeutic Pressure Appliance for Auricular Keloid
Instructions were given to the patients to wear the
appliance continuously throughout the day, to maintain
required pressure. It was made sure that appliance did not
apply undue pressure on the swellings on both right and
left ears. The Patients were also instructed to clean the
appliances with spirit for maintenance of hygiene, and put
on periodic recall at every three months intervals.
Although knowledge about the mechanism of wound
healing and physiology of collagen fibre remodelling has
advanced by leaps and bounds in recent years, treatment
of keloids still remains a therapeutic challenge. They may
lead to significant morbidities such as pruritis, pain and
cosmetic disfigurement. There is still no universally
accepted treatment modality that can ensure complete
resolution of a keloid.11
