Possible Risks of Using Ear Cartilage in Revision Rhinoplasty ?

Hello and thank you for your question. I never use ear cartilage because it lacks structural stability. When septum is present, I always prefer using septal Cartilage. In revisions where there is no septum present, then I will use MTF cartilage for the grafts. I recommend that you seek consultation with a qualified board-certified plastic surgeon who can evaluate you in person.

Best wishes and good luck.

You ask some important questions about the use of ear cartilage in rhinoplasty. In my practice and experience I find that ear cartilage is used ideally in three areas. Ear cartilage is naturally curved which makes it great for rebuilding or strengthening the sides of the nose if there is collapse or weakness. It also can be used to rebuild a nasal tip in cases where the natural tip cartilage are damaged or have been removed. Finally, the perichondrium that covers the ear cartilage makes a great graft for the bridge of the nose. For everything else I prefer to use septal cartilage or rib. The risk of extrusion with ear cartilage is low, it is a living tissue graft and is very safe. It can show through the skin in thin skinned patients if the graft has not been secured and shaped properly. It can be removed if it is no longer needed or wanted. As far as warping, it is already curved in shape so yes it can warp.

I hope this helps.

Ear cartilage is a phenomenal choice of cartilage to use while performing revision rhinoplasty, except for when you want to use it as a straight piece of cartilage, because the ear is not straight, or when you want to use it as structural support because ear cartilage is too weak to give structure. There are some cases where ear cartilage is perfect for revision rhinoplasty while other times ear cartilage is not the right thing to use. The risks of using ear cartilage are minimum, the biggest risk associated with it is if the doctor uses too much of your ear cartilage he/she may create an ear deformity, however that's a rare occurance. The other possible risk could be because the ear has a lot of blood supply is an ear hematoma (bleeding under the skin) but that's also a very rare occurance if the surgery is performed properly.

Anytime you are using cartilage there is potential for warping. That being said, in skilled hands the risk is markedly reduced. When cartilage is correctly placed, it is concealed well and not at risk for extrusion. 

During a primary (first-time) rhinoplasty, cartilage is typically taken from the septum to make grafts that help change the shape of the nose to improve both appearance and breathing.  When a revision rhinoplasty is needed with additional grafts, the cartilage has to be harvested from somewhere else.  This can be from your ear, your rib, or purchased as a cadaver rib.  
Among the autologous (your own cartilage) options, ear cartilage harvest results in a scar that is well concealed within the creases of your ear, is technically easier for the surgeon to harvest, is close of the nose, and has an easier recovery than rib cartilage harvest.  There are minimal donor site risks in harvesting ear cartilage other than possible contour irregularity of the ear, but that is uncommon with good surgical technique.  Despite these advantages, ear cartilage is not always the best option for revision rhinoplasty.  Ear cartilage can be used for minor revisions but is more flimsy and naturally curved.  Therefore, ear cartilage is not ideal for revisions that require major shape changes such as straightening a crooked nose following a previous rhinoplasty.  Ear cartilage is effective for revision rhinoplasty when used as minor contour grafts or when a composite graft (cartilage plus skin) is needed such as for nostril defects.
Your own rib is the most reliable source of cartilage for complex revision rhinoplasty.  There is no substitute for your own rib cartilage in terms of length, strength, straightness, and quantity.  Rib cartilage can be easily harvested through a 1 inch (2.5 - 3 cm) incision over your rib cage.  The main downside of autologous rib cartilage is the small scar on the abdomen or breast crease that is less well concealed than the ear and a more arduous recovery.  However, the advantages of rib cartilage for changing the shape of the nose in complex cases far outweighs the disadvantages compared to ear cartilage.  Due to the technical difficulty or unfamiliarity of operating in the region of the ribs, many surgeons do not offer your own rib cartilage as an option.  However, it is an important option that certainly should be considered strongly for revision rhinoplasty.
Cadaver rib cartilage is also an option that has more rigidity than ear cartilage.  The advantage of using a cadaver rib is that the product is pulled off of a shelf, so the recipient has no donor site problems/scarring.  However, cadaver rib is not as proven as your own cartilage, and it tends to be slightly curved (warped) because it is treated with radiation to remove all of the living cells.  Resorption is the main concern with cadaver rib cartilage over time, which does not typically occur with your own ear or rib cartilage.  Cadaver rib is a purchased product that also adds an additional charge.
The other risks you inquire about such as warping, visibility under the skin, and extrusion can occur with any cartilage grafts.  However, extrusion is extremely rare.  Warping is typically minimal with your own rib cartilage as the majority of shape change occurs on the operating table after it is harvested and precisely cut.  To conceal cartilage grafts under the skin, a fascia graft can be used and placed over the cartilage grafts to add a layer of thickness between the cartilage and skin that minimizes visibility.  As with any surgery, there is always the chance of bleeding, infection, and damage to surrounding structures such as nerves.  However, these risks are very uncommon.  I would recommend an in-person consultation with a surgeon well versed in revision rhinoplasty for more specific recommendations to achieve the natural look you desire.  Best of luck!

Ear cartilage is commonly harvest from one or sometimes both ears to be used in the nose. Harvesting ear cartilage is often safe and does not lead to any ear deformity. The incision is placed in the back of the ear and is invisible when it heals. There is some discomfort, swelling and bruising after surgery but that resolves quickly. If not done correctly, the shape of the ear can change. Another risk is a hematoma but this is avoidable with the right technique. Infection is possible but uncommon.

Every surgeon will have a preference on the type of material to use for revision rhinoplasty.
In my experience, after specializing in revision rhinoplasty surgery for over 10 years, ear cartilage is great as a textbook way for fixing a rhinoplasty, but in reality it does not give you the shape, quality and quantity required for proper surgical repair.
Rib cartilage may provide a better source for your needs.

Ear cartilage is a great material in revision for cartilage depleted noses. Using your own cartilage avoids the risks of implant rejection/infection. It does not resorb. It does not extrude.  All cartilage has risk of showing through the skin if not carved and smoothed meticulously. Your result will depend on the execution of your surgeon not the cartilage.

Ear cartilage is a great choice for reconstructing the lower lateral cartilage. It is a poor choice for any doral or tip support work. Any graft can show after placement if not done with talent and extensive experience in these difficult cases. All cartilage grafts shrink to some degree and must be placed in slightly oversized. All cartilage grafts soften over time so offer very little support. Ear cartilage is great for reconstruction of the lower lateral cartilages because of its natural curves and thin nature.. In the dosum of the nose it offers no support and with eventual shrinkage will always be visible so is a very poor choice in this area.

 I have performed Rhinoplasty for over 20 years and yes, the risk of using conchal ear cartilage anywhere but for the nasal tip, IMHO is that it can warp and dissolve unevenly years after the Rhinoplasty.  This can cause marked indentations and asymmetries, crooked section of the nose requiring a more stable, reliable graft such as a straight silicone implant.  For these reasons, I do not use ear cartilage, rib cartilage/bone, or cranial bone for the nasal bridge.  I only use the straight silicone implant.  I do only use ear cartilage for tip gratfs were it has none of the issue mentioned above.  Hope this helps.
