World’s First Permanent Solution

Over 5,000 pets’ ears restored
with revolutionary PermaStay®

 It may be a Doberman Pincher, Boxer, Great Dane, German Shepherd, Chihuahua or any canine whose ears should stand up straight but don’t for some reason.

Enter Gregg Miller, president of CTI Corporation and creator of CTI’s flagship product Neuticles for Pets, which garnered a 2005 Ig Nobel Prize for Medicine.

In 2010 Miller introduced an ear implant which restores the pet’s ear to a natural look. Considered revolutionary and five years in development, the PermaStay® ear implant has now successfully restored over 5,000 pets Worldwide.

Miller created the implant due to consumer demand. “Almost every day I spoke to a pet owner who said, ‘You need to create a product that corrects broken or bent ears on pets’,” said Miller.

Miller stated that, after investigation, he discovered that a number of products created in decades past were “band-aid fix” products that not only failed to work but in most cases were inhumane.

Conversely, said Miller, PermaStay® Ear Implants not only work, but are humane and will last for the life of the pet.

Crafted of surgical mesh, the implant consists of a 3″ x 4″foundation. The mesh was specially created to be compatible with the sensitive tissue within the pet’s ear and to eliminate risk of migration of the implant within the ear once placed.

In the center of the mesh foundation is a specially designed “spine” made of fluoroplastic. The spine, which varies in length depending on the size of the pet’s ear, was painstakingly developed to prevent trauma inside the ear once placed. It features polished, rounded edges and sides with micro-holes strategically placed throughout.

A second layer of surgical mesh is then sonic welded atop the spine, which not only eliminates risk of inner ear trauma but allows for tissue growth within the surrounding mesh. This tissue growth provides the necessary “wall of support” to keep the ear erect, Miller said.

Three sizes of implants are now available for any canine, large or small. 

PermaStay® is light as a feather. The pet doesn’t know it’s there, and best of all, it’s normally undetectable once placed,” Miller said. “In cases where there  is an indentation of the spine viable. the spine, at the pet owners’ option. can have the spine removed.”

Miller stressed that PermaStay® not only restores the pet’s ears, but it is instrumental in maintaining the pet’s health.

“Pets whose ears should stand up but do not are normally prone to ear infections, while an erect ear allows air flow into the ear canal,”said Miller. “When that air flow is obstructed, the pet is at risk for ear infections and related medical issues.”

According to Miller, there are 319 authorized facilities worldwide which participate in PermaStay® implantation. Miller said it is important to have a veterinarian that has expertise with pet ears implant the product. As such, sales are vetted and restricted to veterinarians that have ear crop experience.

“Along with the cost of implants and depending on the particular vet and location in the World, implantation can run from $600 to $1,500 per ear,” said Miller. “But most pet owners will agree it’s well worth it.

The indications for implanting PermaStay® prosthetic implants are quite varied. As a general statement, incorrect ear posture of the erect eared breeds of dogs, is the most routine reason for its use. The most routine indication is to correct cartilage breaks or folds in post surgical ear trim situations. This occurs most commonly in Doberman Pinchers, but also in Great Danes and Boxers. It can occur in any breed of dog for many different reasons. To list a few: overall health of the dog, nutrition, genetic predisposition, weak cartilage, muscle/nerve control, trauma, and improper surgical procedure and/or aftercare. The results judged very pleasing by one owner or veterinarian may be judged very poor by another. Be aware that in severe trauma cases, inadequate blood supply may be a very important factor on the success of this implant surgery. PermaStay® is provided non-sterile by the manufacturer. Sterile technique is absolutely essential. PermaStay® is crafted from three parts:

  1. Surgical Mesh Foundation The surgical mesh foundation is designed to provide support for the spine once implanted as the material will allow tissue growth through the mesh.
  2. Fluroplastic Spine The Fluroplastic spine is crafted to provide optimum support and tissue growth. The spine is carefully made with rounded edges and corners as to not create inner ear trauma once implanted. Multiple holes are strategically placed to allow tissue growth which will aid in ear support. The spine can be removed 60 days after.
  3. Surgical Mesh Overlay The Surgical Mesh Overlay is sonic welded atop the Fluroplastic spine to provide support, eliminate risk of potential trauma from the spine and to allow tissue growth which will provide added support.


The prognosis for good results improves with experience in ear trimming and aftercare, and of course; experience in installing PermaStay®. This procedure should only be performed by a licensed veterinarian with prior ear cropping experience. A clear working knowledge of the anatomy and physiology of the canine ear is essential. Utmost care in surgical principles and aseptic technique is required. Infection and complication risks are higher when installing a prosthetic material than when doing a routine ear trim. The prognosis of success exceeds 95% when you carefully follow these principles and when the break or fold is located in the middle 50% of the ear concha.

Surgical Procedure

Procedures for correcting improper carriage or break in the mid 50% of the affected ear concha.

1. Clip hair and prepare the surgical area; extending the prepped area 4 to 5 cm onto the skin around the base of the ear.

2. Place one or two sterile cotton balls into the ear canal.

3. Make incision through skin and cartilage on the concave surface of the concha. Incision usually is parallel with the long axis of the ear.The incision should extend 2 to 3 cm both distal and proximal to the break in the cartilage. Blunt dissection of the subcutaneous fascial tissue connection between cartilage and skin (on the convex surface) should extend 1 to 3 cm around the entire incision peripherally. Under no circumstances should the spine be cut, trimmed or altered in any way.Note: Very little hemorrhage is expected; however, a clotting time should always be checked. Also withhold any aspirin 3 days before and after surgery. To avoid risk of mesh migration suture corners of mesh and centered near spine with dissoluble material. 

4. Close incision with simple horizontal mattress sutures- Vicryl-0 material.

5. While each ear varies it is the option of the surgeon to TempoStay® or bandage the ear following the procedure. It is recommended that the ear be supported with either the TempoStay® or bandaging after placement of PermaStay® for 60 to 90 days to allow uninterrupted tissue growth formation into the surgical mesh.

6) While the surgical mesh can be custom trimmed to conform with the pets ear, under no circumstances  should the spine be altered in any way.



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 unnecessary but is at the option of the surgeon. Elizabethan collars should be used only if absolutely necessary and under supervision.

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.

Expected Results

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%. This prognosis is
with breaks in the middle 50% of the ear. Those that occur in the
proximal or distal 25% of the ear will have a somewhat 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 occur.

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 discharge.

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 mechanisms.

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 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.

Reported Issues

5017 canines have been implanted with PermaStay®. (REV 11//2019)

1) 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 life of the pet.

6) PermaStay® was placed in approximately 38 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
devices placed.

» 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
procedurally 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 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% 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 will 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 extreme cases,
drain the ear which is a very 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
satisfactory manner.

» 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 any trauma to the ear especially for the first
few months following the procedure. Avoidance of trauma to the ear for
the pet’s life is essential. PermaStay® is
no different than any other procedure for pets or humans. If
post-operative care or cautions are ignored the risk of an issue with
the pet increases and will add to the 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
healthier life.
