Cheek Implants

Clinical Overview of Cheek Implants (Malarplasty)

Cheek augmentation, medically referred to as malarplasty or submalar augmentation, is a surgical procedure designed to enhance the contour of the face by augmenting the skeletal structure of the zygomatic arch (cheekbone). While dermal fillers provide a temporary solution for volume loss, cheek implants offer a permanent structural alteration. The procedure involves the surgical placement of synthetic biocompatible materials over the natural bone to project the cheek mound, correct facial asymmetry, or restore volume lost due to aging or trauma.

From a clinical perspective, the mid-face is a critical component of facial harmony. High, prominent cheekbones are often associated with youth and beauty, as they provide a lateral anchor for soft tissues. As the face ages, the malar fat pad descends, causing a flattening of the mid-face and the formation of nasolabial folds. Cheek implants address this by re-establishing the skeletal projection, effectively lifting the overlying soft tissues and creating a more defined transition between the mid-face and the lower eyelid.

Biocompatible Materials

The selection of implant material is a critical decision in the pre-operative planning phase. The vast majority of facial implants are constructed from solid silicone or porous polyethylene (Medpor).

• Solid Silicone: These are smooth, flexible implants that do not integrate with the surrounding tissue but are encapsulated by the body's fibrous capsule. Their primary advantage is ease of removal and a low risk of infection due to their non-porous nature.
• Porous Polyethylene (Medpor):strong> This material allows for tissue ingrowth (vascularization), meaning the body's tissue grows into the pores of the implant. This creates a very stable fixation that resists migration. However, removal is significantly more difficult than with silicone.
• Polytetrafluoroethylene (ePTFE):strong> A softer, mesh-like material that also allows for tissue integration, often used in patients with very thin soft tissue coverage to reduce the risk of visible edges.

Ideal Candidates

Identifying the ideal candidate for cheek augmentation requires a comprehensive evaluation of the patient's skeletal anatomy, skin elasticity, and aesthetic goals. Candidates typically fall into two categories: those seeking aesthetic enhancement and those requiring reconstructive correction.

Aesthetic Indications

• Hypoplastic Zygoma: Individuals with genetically underdeveloped cheekbones who desire a more sculpted, "high-fashion" facial structure.
• Mid-Facial Volume Loss: Patients experiencing early to mid-stage signs of aging where the cheeks have flattened, causing a "tired" appearance despite good skin quality.
• Facial Asymmetry: Patients with noticeable unevenness in the cheekbones due to developmental issues or previous trauma.

Clinical Contraindications

Suitable candidates must be in good general health, free from active infections or chronic illnesses that impair healing (such as uncontrolled diabetes or autoimmune disorders). Smokers are generally advised to cease smoking several weeks prior to and after surgery, as nicotine constricts blood vessels and significantly increases the risk of wound dehiscence and tissue necrosis. Furthermore, patients must have realistic expectations regarding the outcomes; implants add projection but cannot alter the skin texture or the fundamental shape of the jawline.

Surgical Techniques

Cheek implantation is typically performed under general anesthesia or intravenous sedation. The surgical approach depends on the patient's anatomy and the surgeon's preference, generally categorized into intraoral (inside the mouth) and extraoral (external) approaches.

Intraoral Approach

This is the most common technique. The surgeon creates an incision inside the upper lip, above the gum line (the vestibular incision). This approach leaves no visible external scars. Using specialized instruments, the surgeon elevates the soft tissue (periosteum) from the zygomatic bone, creating a precise pocket. The size of the pocket is critical; it must be tight enough to hold the implant in place but large enough to prevent distortion of the overlying tissue. Once the implant is inserted, the surgeon checks for symmetry and proper positioning. The incision is then closed with dissolvable sutures.

Extraoral Approach

Less frequently used for standard augmentation, the external approach may be necessary if the procedure is combined with a facelift or blepharoplasty. An incision is made directly below the lower eyelash line or within the hairline near the temple. While this provides direct visualization, it carries a higher risk of visible scarring and external trauma to the eyelid (ectropion), though it avoids the bacterial environment of the oral cavity.

Fixation Methods

While some surgeons rely on the tightness of the tissue pocket to secure the implant, others utilize rigid fixation. This involves using a small titanium screw to anchor the implant to the underlying bone. Rigid fixation eliminates the risk of implant migration (shifting), which is the most common cause of revision surgery in malarplasty.

Recovery Timeline

Recovery from cheek implant surgery is relatively straightforward compared to more invasive osteotomies, but it still requires a dedicated healing period.

• Days 1–3 (Acute Phase):strong> Patients will experience significant swelling, bruising, and moderate discomfort. A liquid diet is usually mandatory if the intraoral approach was used to prevent disturbing the sutures. Cold compresses are applied to reduce edema. Patients may have difficulty speaking or smiling due to tightness.
• Week 1 (Subacute Phase):strong> Bruising will begin to fade, changing from purple to yellow. Swelling will persist but will start to subside. Sutures inside the mouth will begin to dissolve or be removed. Patients can usually return to sedentary work after 7 to 10 days, though residual swelling may still be visible.
• Weeks 2–4 (Early Healing):strong> Most external swelling resolves. Numbness in the upper lip and cheek is common due to manipulation of the infraorbital nerve; sensation typically returns gradually. Patients may resume light exercise.
• Months 3–6 (Maturation):strong> The final contours of the face become apparent as the soft tissues fully drape over the new implant. The implants will feel firm and natural to the touch. Any minor asymmetry usually settles out during this period.

Risks and Complications

As with any surgical procedure, malarplasty carries inherent risks. While complications are relatively rare when performed by a board-certified plastic surgeon, patients must be informed of potential adverse outcomes.

• Infection: Because the intraoral approach passes through bacteria-rich mucosa, there is a risk of postoperative infection. If an infection persists despite antibiotics, the implant may need to be removed.
• Implant Malposition or Migration: If the pocket created is too large, or if fixation is not used, the implant may shift from its intended position, creating asymmetry or an unnatural contour. This requires revision surgery.
• Nerve Injury: The infraorbital nerve, which provides sensation to the cheek and upper lip, runs near the surgical site. Temporary numbness (paresthesia) is expected, but permanent nerve damage resulting in chronic pain or numbness is a rare but serious complication.
• Hematoma: A collection of blood under the skin or in the surgical pocket can cause pressure and pain. Small hematomas resolve on their own, but larger ones may require drainage.
• Asymmetry: Natural facial asymmetry exists in all humans. While the surgeon strives for balance, perfect symmetry is surgically impossible. Visible discrepancies may require adjustment.
• Extrusion: In rare cases, the implant may erode through the soft tissue or the gum line, necessitating removal.

Costs

The financial investment for cheek implants varies significantly based on geographic location, the surgeon's expertise, the complexity of the procedure, and the type of anesthesia used.

• Surgeon’s Fee: This is the primary cost and reflects the surgeon’s skill and experience. It typically ranges from $2,500 to $5,000.
• Anesthesia Fee: If general anesthesia is required, the fee for the anesthesiologist and the facility usually ranges from $1,000 to $1,500.
• Operating Room Facility Fee: Hospitals or accredited surgical centers charge for the use of the operating theater and nursing staff, generally between $800 and $2,000.
• Implant Costs: The cost of the actual medical device is usually included in the surgeon's fee but can be itemized, ranging from $400 to $1,000 depending on the material (e.g., custom carved implants cost more).

On average, the total cost for cheek augmentation surgery in the United States ranges from $3,500 to $7,000. It is important to note that this is considered an elective, cosmetic procedure. Therefore, costs are not typically covered by medical insurance unless the surgery is reconstructive (e.g., following trauma or correcting a congenital deformity). Patients should also budget for potential revision surgeries, prescription medications, and post-operative garments or dressings.
