Early outcomes and risk factors for complications after facial alloplastic implant surgery: An ACS-NSQIP study

BACKGROUND

Facial implantology (FI) is a growing field in facial surgery that focuses on harmonizing and balancing facial features. Despite its increasing popularity, larger-scale studies on FI outcomes and risks are scarce.

METHODS

The ACS-NSQIP (2008-2021) was queried to identify patients who underwent combined/isolated alloplastic FI surgery of the malar/mandibular region. Based on CPT codes (21125; 21270), procedures were subdivided into combined or isolated FI surgery of the malar or the mandibular region.

RESULTS

The study population included 84 patients, of which n = 19 (23%), n = 10 (12%), n = 33 (39%), and n = 22 (26%) underwent combined malar, isolated malar, combined mandibular, and isolated mandibular FI surgery, respectively. Isolated malar (total n = 10) and mandibular FI surgery (total n = 22) patients had relatively high comorbidity rates with up to n = 6 (60%) active smokers and n = 9 (41%) with hypertension, respectively. Combined malar (n = 19) and mandibular FI surgeries (n = 33) had the highest complication rates with n = 3 (16%) and n = 5 (15%) patients experiencing any complications. For both isolated malar and mandibular FI procedures, n = 1 (10% and 4.5%) patient reported any complications.

CONCLUSION

In this study, we accessed the ACS-NSQIP database and found alloplastic augmentation for zygoma and mandible to be safe. Patients who underwent combined procedures and mandibular augmentation were more likely to show complications or require inpatient stay. Most alloplastic augmentations of mandible or zygoma were combined with other procedures (62%) which suggests that alloplastic facial implants (in the academic setting) are often used as an adjunct in the treatment of complex craniofacial disorders.

Balancing beauty and science: a review of facial implant materials in craniofacial surgery

Facial reconstruction and augmentation, integral in facial plastic surgery, address defects related to trauma, tumors infections, and congenital skeletal deficiencies. Aesthetic considerations, including age-related facial changes, involve volume loss and diminished projection, often associated with predictable changes in the facial skeleton. Autologous, allogeneic, and alloplastic implants are used to address these concerns. Autologous materials such as bone, cartilage, and fat, while longstanding options, have limitations, including unpredictability and resorption rates. Alloplastic materials, including metals, polymers, and ceramics, offer alternatives. Metals like titanium are biocompatible and used primarily in fracture fixation. Polymers, such as silicone and polyethylene, are widely used, with silicone presenting migration, bony resorption, and visibility issues. Polyethylene, particularly porous polyethylene (MedPor), was reported to have one of the lowest infection rates while it becomes incorporated into the host. Polyether-ether-ketone (PEEK) exhibits mechanical strength and compatibility with imaging modalities, with custom PEEK implants providing stable results. Acrylic materials, like poly-methylmethacrylate (PMMA), offer strength and is thus mostly used in the case of cranioplasty. Bioceramics, notably hydroxyapatite (HaP), offer osteoconductive and inductive properties, and HaP granules demonstrate stable volume retention in facial aesthetic augmentation. Combining HaP with other materials, such as PLA, may enhance mechanical stability. 3D bioprinting with HaP-based bioinks presents a promising avenue for customizable and biocompatible implants. In conclusion, various materials have been used for craniofacial augmentation, but none have definitively demonstrated superiority. Larger randomized controlled trials are essential to evaluate short- and long-term complications comprehensively, potentially revolutionizing facial balancing surgery.

Factors causing stress in women with babies 0-3 months old and their coping styles

This study was conducted in order to identify the factors that cause stress in women who have babies aged 0-3 months and the ways to deal with stress. This descriptive study was conducted in outpatient clinics for newborns. The sample consisted of 322 women. Data were collected through a questionnaire and Ways of Coping with Stress Inventory. It was found that most of the women became stressed because of problems regarding self-care, baby care and social life. Women mostly used ineffective coping styles to cope with stress.
