As with routine ear trim surgery, proper aftercare is a very
important part of improving the probability of good results. Edema,
seroma, hematoma and infection are more likely than with routine ear
crop surgery when optimal post-operative care is not employed. It is
recommend that a broad spectrum antibiotics be administered for 10 days.
External application of additional apparatus to help the ear stand is
usually recommended but is at the option of the surgeon.
Pain medication and or tranquilizers should be prescribed as needed.
Evaluate the surgery on day two or three and again at ten days. At this
time, remove the sutures and determine if other aftercare or ear
training apparatus is indicated. Use of Rimadyl is advised several days
prior to surgery and for up to 10 day preceding surgery to reduce
post-operative swelling of the ear due to trauma.
With proper overall evaluation of the animal’s health, good surgical skill and thorough post-operative care, a very high percentile of these broken ears will stand very well, probability is 99%-plus. This prognosis is with breaks in the middle 50% of the ear. Those that occur in the
proximal or distal 25% of the ear may have a lower probability. The individual surgeon will need to carefully evaluate these cases and discuss the prognosis with the owner according to his/her judgment as no two ears are rarely precisely alike.
PermaStay® has proven to be well over 99% non reactive to canine tissue in all
previous tests and clinical uses. Successful installation should last
the life of the canine without complications providing pet owner follows
post-operative protocol.. Appearance of the prosthesis material is
non-existent in most cases.
Pet should be healthy prior to placement without any known allergies
or low immunity. It is suggested that a full blood panel be conducted
prior to surgery to determine health of the pet. Reactive canine tissue
cases cited above occurred when pre-operative blood testing did not
The fluroplastic spine can be removed after six months in most cases-
if desired. Removal of the spine will restore the pet’s ear to a
natural state. Exclusions of spine removal are those pets where ear
canal placement was necessary.
It is strongly advised that corners of the surgical mesh foundation
and center of the implant be anchored with dis-solvable sutures designed
to hold implant in place for up 90 days or preferably longer
It is strongly advised to place the pet on Rimadyl several days prior
to surgery and for 10 days following surgery to greatly reduce or
eliminate post-operative trauma fluid discharge. Surgeons using laser
technology have experienced little to no post- operative fluid
While it is at the option of the surgeon, it is advised that post- operative TempoStay® Ear
Supports, traditional ear support or bandaging be employed in an
upright position to allow not only tissue growth into the surgical mesh
foundation- but to add additional ear support resulting in less stress
to the ear. Pet owner observation is critical to assure pet does not
oppose this as the ear can be traumatized in pet’s effort to remove
PermaStay® is sent to the veterinarian pre-washed and dried in 70% Isopropyl
Alcohol. Steam autoclave at 250 (DF) is required prior to placement in
the autoclave pouch in which it is packaged. At surgeons’ option the
device can be soaked prior to placement with a broad-spectrum antibiotic
– which is recommended.
When protocol is breached, like with any specialized or
non-specialized procedure, the risks of complications increase.
Correction of the breach is normally correctable with veterinary follow
up care. In extreme rare instances removal of the implant is necessary.
In some cases when the implant is removed the ear remains erect.
Initial procedural success can normally be determined if the ear(s) are
standing immediately after placement of the device, Potential causes
leading to post-operative procedural complications or failure are, but
not limited to post-operative contamination of the surgical area, severe
trauma or surgeon implantation failure.
Post operative scar created by the incision area required for placement of the implant is a concern with every pet owner. Two one CC tubes of CTI ScarGON gel are included with each device at no charge. Simply wait for the scab to fall off the area naturally then apply a micro-thin coating of ScarGON to the area. Gently rub the ScarGON into the affected area twice a day for up to seven days and the scar will completely disappear! ScarGON gel is available in .50 oz tubes – simply click the ScarGON logo atop the page for details.
5017 canines have been implanted with PermaStay®. (REV 11//2019)
1) Several canines had experienced a mesh migration. It is now advised that
corners of the surgical mesh foundation and center of the implant be
anchored with a non traumatic dissoluble suture which will last for 60
days or longer avoid this possible occurrence.
2) 317 canines had experienced mild to severe post operative fluid
buildup in the ear due to placement trauma. 107 of the 317 canines had
required drainage of the ear while the remainder absorbed back into the
body without drainage after several days. Surgeons using laser
technology have experienced little if any post operative swelling. It is
now required that the pet be placed on Rimadyl several days prior to
surgery and for seven to ten days following placement of PermaStay® to eliminate risk of this minor issue.
3) Two German Shepherd canines (in 2010) experienced what appeared to be a post operative allergic reaction and rejection. Pets, prior to placement of PermaStay® should be of excellent health including immune system and not have any known allergies for one year prior to placement. A full blood panel is recommended prior to placement to assure pet’s fitness prior to placement.
4) Four canine ears- where the break of fold was midway – were corrected with PermaStay® but the fold reoccurred below the implanted area but was corrected.
5) Nine canines have developed post operative infections –
months after placement. Investigations have proven that trauma to
the ear or failure to keep surgical area sterile during the healing
process is the sole reason for this occurrence. Pet owners are advised
to seek veterinary assistance immediately should fluid formation occur
to prevent an infection which may develop if ignored. Caution and care
to avoid severe trauma to the ear must be employed by the pet’s owner
for the first six months and a level of caution for the life of the pet.
6) PermaStay® was placed in eight canines and the ear still did not stand.
Reasons for this may include unauthorized surgeon’s inability to place PermaStay® properly, post operative trauma to the ear dislodging the support spine or severe trauma to the ear in general.
7) It should be noted that while PermaStay® is safe and effective – pet owners are advised to follow post operative protocol which is important for procedural success. Failure by the pet’s owner to follow post operative cautions may lead to follow up visits to the veterinarian which will add to the cost of the procedure. The PermaStay® procedure should be performed by an authorized participating facility who has been vetted and approved by CTI Corporation.
Frequently Asked Questions
» Can any veterinarian place PermaStay®?
No. Sales to veterinarians, or to pet owners that order providing the PermaStay(s) to the surgeon, are restricted to those vets that do ear crops on a regular basis with a known success rate. The PermaStay® procedure is highly specialized which requires a surgeon with an expertise, passion and forte’ with ears.
» Is there a veterinarian in my area?
PermaStay® maintains a database of over 100 participating clinics and hospitals
throughout the US. Email or call for an authorized participating
facility in your area or region. Pet owners are provided with full
disclosures of the surgeon’s procedure history including the numbers of
» What makes a “participating facility a participating facility?”
Our sole concern is procedural success To assure this, we restrict
the procedure to veterinary surgeons that perform ear crops on a regular
basis with a proven success rate. After each procedure, we contact that
veterinarian to make sure the procedure went well. A second follow up
contact is made several months later. We attempt to keep in contact with
the pet owner encouraging their feedback on how satisfied they are with
their pet’s procedure and the veterinary facility. As a result, over
the years, we have developed a database with what we consider the best
ear specialists in the World.
» I’m outside the US – is PermaStay® available in my country?
Maybe. There are PermaStay® participating facilities in 14 countries throughout the World.
» How long has PermaStay® been on the market?
PermaStay® was in development for nearly five years prior to its introduction in
2010. Development included clinical trials with a host of participating
veterinarians specialized with ears. PermaStay® was
proven safe and effective prior to release when post-operative care
protocol is followed. It is the first product in the history of
veterinary medicine to provide a lifelong solution to a bent or broken
ear. CTI Corporation is first and only company in the World that has
provided safe and effective pet implantation devices for over a quarter
» Can the spine in the center of PermaStay® be removed?
The spine serves initially as a crutch to support the ear whilst
tissue growth occurs within the mesh foundation. Once tissue growth has
occurred, which varies in time from pet to pet, the device can easily be
removed. When the spine is removed the ear is normally restored to a
natural state. The spine can be removed any time after six months or
sooner if there is assurance that tissue growth within the mesh
foundation has occurred.
» Is the procedure major surgery?
No. Normal implant time is from 15 to 20 minutes per ear. Watch our
instructional video above to see an actual procedure. The level of
surgery compares to a neuter or spay. While the surgery itself is not
major, the skill and expertise of the veterinarian is essential.
» Are there complications?
With any surgical procedure there are risks of complications. 30% of
procedural successful ear crops, for example, fail as the pet’s owner ignores or neglects post-operative care and cautions. With PermaStay®,
it is essential that the ear is not severely traumatized especially for the
first 90 days. Trauma to the ear can occur in many ways from mild to
extreme. If trauma to the ear does occur that does not mean procedural
failure will occur. It simply means that a follow-up visit(s) to the
surgeon may have to be made to correct the specific issue created by the
trauma which is generally accumulated fluid discharge which is easily
corrected. In these cases, the pets owner should not wait months to
correct the issue but should be addressed immediately. Refer to Reported
Complications on this page for a comprehensive listing. Complications
are generally post-operative issues which arise due to non-intentional
owner neglect created by trauma to the ear which can be avoided with
proper supervision and awareness.
» What is the complication rate?
PermaStay® maintains a 95% success rate or greater. Non-success is not 100%
procedural failure but can be defined, for example, as any issue listed
under Reported Complications on this page. It is estimated that less
than 1/4 of 1% of implanted pets result in procedural failure requiring removal
of the device. Complications are normally issues which arise due to
non-intentional pet owner neglect.
» How much does PermaStay® cost?
Cost for the entire procedure, including the PermaStay® implant(s)
range from $600 to $1500 per ear depending on each veterinarian’s fee
schedule and location within the country. Generally, pet owners can
expect to pay approximately $1000 per ear on average.
» What if my pet does traumatize the ear(s)?
If the trauma is severe then the body may react with a fluid
discharge. If the fluid is ignored by the pet’s owner and does not
absorb back into the body, there is a risk of the fluid
decaying-contaminating the ear over time which will lead to an
infection. After placement of PermaStay®,
check the ear frequently. If you notice an unusual area which may
contain fluid contact your vet immediately. The veterinarian will
provide either an anti-inflammatory medication or in some cases,
drain the ear which is a very inexpensive, simple, quick and painless procedure.
» Are follow up visits required?
Pursuant to the surgical procedure description on this page it is
recommended that a follow-up visit to the veterinarian be made two or
three, ten and 30 days following the procedure as a check-up to assure
that all is well. The follow-up visits are normally included in the cost
of the procedure. These visits include the removal of stitches and
general examination of the ear(s) to make sure all is progressing in a
» At what age can PermaStay® be placed?
It is recommended that PermaStay® be placed at full growth of the pet- generally after one year of age. It is recommended that the ear be supported with TempoStay®
Ear Supports until that time to support the ear(s) as scar tissue will
likely form at the breaking point of the ear. Information on TempoStay® can be found by clicking the TempoStay® logo at the top of the page.
» Is post-operative care difficult?
As noted above. it is important to follow veterinary care
instructions and avoid trauma to the ear especially for the first
six months following the procedure. Avoidance of trauma to the ear for
the pet’s life is recommended. PermaStay® is
no different than any other procedure for pets or humans. If minimal
post-operative care or cautions are ignored the risk of an issue with
the pet increases and will add to the overall cost of the procedure.
» Are there medical benefits with PermaStay®?
Yes. In many cases it is important to have a standing ear(s) as it
allows air flow into the ear canal which greatly decreases risk of ear
infections for the pet. Allowing an infected ear to remain untreated is
not only harmful to the pet but can lead to hearing loss in extreme
cases. PermaStay® is the only product in pet history to provide to provide a permanent
solution to a bent or broken ear allowing your pet to live a happier and
