Facial implants are employed to correct contour, symmetry, and proportion in patients with congenital deformities, posttraumatic volume loss, or age-related resorption of facial bone and soft tissue. These conditions often result in aesthetic imbalance, asymmetry, and psychosocial distress. Ideal candidates are individuals with localized contour deficiencies unresponsive to soft tissue augmentation. Contraindications include incomplete craniofacial growth, large volume deficits more appropriately addressed by alternative treatments, active infection, inadequate bony or soft tissue support, and unrealistic aesthetic expectations. Facial implants, composed of biocompatible materials such as silicone, porous polyethylene, and titanium, provide durable volume enhancement through direct skeletal augmentation. Preoperative analysis using 3-dimensional imaging assists in selecting the appropriate implant type, size, and position. Surgical approaches vary by region, with intraoral or external incisions used to create precise subperiosteal pockets for implant placement. Challenges include ensuring stable fixation and avoiding malposition or asymmetry. Potential complications include infection, extrusion, nerve injury, and contour irregularity. This activity for healthcare professionals is designed to enhance learners' competence in evaluating and treating the aging, traumatic, or atrophic chin, mandibular angles, and malar regions with facial implants. Participants will gain valuable insights into the procedure's indications, contraindications, and proper technique, enabling them to contribute meaningfully to interprofessional teams caring for patients with facial asymmetries. Objectives: Assess patients for possible chin, midface, and mandibular angle implant indications. Determine the appropriate facial implant material and surgical technique for a patient with facial asymmetry. Improve patient understanding of the risks, benefits, and contraindications associated with various facial implant types. Collaborate with all members of the interprofessional team, including specialists such as otolaryngologists, anesthesiologists, and oral maxillofacial surgeons, to provide efficient, comprehensive, and coordinated care for patients requiring facial implants.

Facial implants are used to enhance the aesthetics of the aging or underdeveloped face or correct asymmetry resulting from trauma or congenital malformations. Common augmentation sites include the chin, zygomas, and mandibular angles. According to the 2020 American Society of Plastic Surgeons member survey, malar implant surgery was the most frequently performed facial implant procedure and ranked as the 3rd most common cosmetic surgical procedure overall. The use of malar implants has increased by 938% since 2000, while chin implant procedures have risen by 63% during the same period. Although less frequently performed, facial implants may also be placed on other bony surfaces, including the nose, glabella, and temple.[1] Systematic reviews in 2024 and 2025 report pooled complication rates ranging from 4% to 11%, with lower rates in malar and chin implants and higher rates in paranasal regions.[2] The ideal implant material is chemically inert, biocompatible, and easily manipulated. Despite these properties, implants are foreign bodies and carry inherent risks. Facial implants may be organic or synthetic. Among the synthetic materials used in the U.S., high-density polyethylene (HDPE), silicone, and titanium remain the most prevalent. Autogenic grafts, once widely employed, have declined in popularity due to long-term variability and limited predictability.[3] One of the most common complications associated with facial implants is poor cosmesis, frequently resulting from asymmetry. Less common but more severe complications include infection and bone erosion. These conditions may necessitate implant removal, which is more technically challenging for porous implants that permit soft tissue ingrowth than for solid implants surrounded by a fibrous capsule.[4][5] Advances in software-assisted analysis have improved the evaluation of facial defects and the determination of appropriate surgical interventions. Facial analysis continues to evolve with the integration of 3-dimensional (3D) treatment planning technologies. Two-dimensional (2D) imaging remains valuable for assessing bony relationships and correlating these structures with soft tissue contours. For example, lateral cephalograms form the basis of genioplasty evaluation, whereas assessing midface deficiencies remains more difficult with 2D radiographs and may benefit from additional research and imaging refinements.

Objective criteria have been developed to guide implant selection and surgical planning. However, aesthetic preferences influenced by societal trends must also be considered. Optimal outcomes depend on diagnostic precision, thorough facial analysis, appropriate implant choice, and meticulous surgical execution.

Complications following facial implant placement may arise early during recovery or months to years postoperatively. Definitions of “early” and “late” vary among studies. For this activity, “early” refers to the first few weeks of soft tissue healing.[38] Reported complications include the following: Hematoma Seroma Infection Wound dehiscence Alveolar ridge resorption Poor or undesired aesthetic outcome Displacement or malpositioning Scarring Nerve injury Bleeding is an early complication and may produce an expanding hematoma requiring drainage, typically secondary to inadequate hemostasis during surgery. Seromas may develop following implant placement due to inadvertent local gland disruption or the inflammatory response to the implant or surgical manipulation. Conservative subperiosteal dissection can minimize fluid accumulation. Management options include observation with or without antibiotic therapy, fluid aspiration, and, when necessary, repeat surgical intervention to control bleeding. Late complications following facial implant placement include infection, implant mobilization, extrusion, and bone resorption. Recent systematic reviews and meta-analyses have quantified complication rates, reporting a pooled infection rate of approximately 2% to 5% for alloplastic implants and displacement in 1% to 3% of cases. Porous polyethylene implants exhibit lower rates of bone resorption compared with solid silicone implants, likely due to soft tissue ingrowth and improved load distribution. These findings highlight the necessity of careful patient selection, precise implant positioning, and rigorous postoperative management to reduce complication risk. Intraoral incisions reduce the likelihood of visible scars, although some evidence suggests a potential increase in infection risk, which remains controversial. Persistent infection unresponsive to antibiotic therapy necessitates implant removal to prevent further morbidity.

Persistent infection unresponsive to antibiotic therapy necessitates implant removal to prevent further morbidity. Improper implant size, shape, or placement may result in functional deficits such as lip incompetence. In chin implants, active engagement of the mentalis muscle, which compensates for weakness, increases pressure on the underlying implant. Placement at the inferior mandibular border, where cortical thickness is greater and the implant is further from the mentalis insertion, has been associated with reduced bony resorption. Implant fixation mitigates micromovements that contribute to ongoing erosion. Although debated, reported erosion is generally self-limiting, with fixation presumed to influence this process. Esthetic asymmetry may arise from implant folding or migration due to inadequate fixation, suboptimal subperiosteal placement, or insufficient dissection. Implant sizers assist in confirming appropriate dimensions before final placement. Cases of malposition or displacement are corrected surgically, either by securing the implant in the correct position or replacing it with an implant of a more suitable size and shape.

Cases of malposition or displacement are corrected surgically, either by securing the implant in the correct position or replacing it with an implant of a more suitable size and shape. Poor cosmesis may result from inadequate reapproximation of the mentalis muscle, which is encountered and incised during intraoral chin implant procedures. The mentalis originates from the mandibular incisive fossa and inserts into the dermis of the chin, functioning to elevate the chin. Inadequate dissection, incision, or reapproximation techniques may produce ptosis, commonly referred to as “witch’s chin.” Extraoral approaches eliminate the risk of mentalis ptosis but introduce the potential for a visible submental scar. Neurologic complications, including dysesthesia, hypoesthesia, and anesthesia, may arise from injury to the mental nerve, which provides sensation to the ipsilateral chin and lower lip. This nerve must be identified and preserved during augmentation procedures. Mental nerve injury has been reported in approximately 2.4% of cases, frequently associated with alveolar ridge resorption. Persistent nerve dysfunction may necessitate implant removal or replacement with a prosthesis of a more appropriate fit.

An interprofessional approach optimizes outcomes in facial implant surgery. The primary care or cosmetic physician initially identifies the indication and refers the patient to an appropriate surgical specialist. Qualified surgeons include plastic surgeons, oral and maxillofacial surgeons, and otolaryngologists. After surgical evaluation, active patient participation throughout the planning, operative, and recovery phases is critical to ensure procedural success. In outpatient settings, local anesthesia may be administered by the surgeon for awake procedures. An anesthesiologist provides expertise when deep anesthesia or advanced analgesic techniques, such as nerve blocks, are required. Nursing staff assist the surgeon intraoperatively, monitor patients during recovery, administer medications, and reinforce patient education. This collaborative model supports patient safety and high-quality care. The U.S. Food and Drug Administration regulates implantable medical devices, and the range of approved materials continues to expand. Patients must be informed of device-specific risks. For example, silicone implants demonstrate no increase in reactive oxygen species or genotoxicity but may induce bony resorption when placed on the chin, as previously discussed.[40]
