Abstract
Many different methods achieve male facial augmentation. Arranged from shorter- to longer-term results, these methods include filler, fat/tissue grafting, fat/tissue transposition, and alloplastic implants. This study solely reviews allografts, which provide the most predictable hard-tissue augmentation. An array of alloplasts will be discussed in this study including chin, cheek, mandibular angle, frontal, and temporal implants. The most common and severe complications will also be explored with preventative and treatment algorithms.

Abstract
the aim of this paper, is to propose a new reference line: the Frontozygomatic-Infraorbital Line (FZ-IOL). This reference line can guide the surgical team planning mandibular angle harmonization, based on the patient's skeletal proportion. The Frontozygomatic-Infraorbital Line has been adopted for symmetrization surgery, masculinization surgery, and in unsatisfactory results of previous orthognathic surgery. From March 2021 to December 2022, 3 patients were treated for severe facial asymmetry affecting mainly the lower third of the face. All cases were planned with the reference FZ-IOL. Patients were treated in the same center, at the Orthognathic Surgery Department of the Instituto Portugues da Face, Lisbon, Portugal. The Frontozygomatic-Infraorbital Line is designed virtually using software to reconstruct a 3D image from a digital imaging and communications in medicine (DICOM) file obtained from a cone beam computer tomography (CBCT). , connecting the two orbital rims. Then, a vertical line, the frontozygomatic line perpendicular to the IOL and passing through the outmost lateral portion of the frontozygomatic suture is drawn. The proposed line demonstrated how establishing appropriate reference lines is crucial for the success of the surgery. The selection of reference lines should be based on the patient's anatomy, the symmetrization process's complexity, and the surgery's desired outcome. The Frontozygomatic-Infraorbital Line represents an adequate reference line for managing mandibular angle lateral projection, improving lower third of the face symmetrization.

Abstract
BACKGROUND Aesthetic facial bone surgery and facial implantology expand the boundaries of conventional facial surgery that focus on facial soft tissue. This study aimed to reveal novel aesthetic facial measurements to provide tailored treatment concepts and advance patient care. METHODS A total of n=101 study participants (46 females and 55 males) were presented with 120 patient portraits (frontal images in natural head posture; 60 females and 60 males) and asked to assess the facial attractiveness (scale 0-10; "How attractive do you find the person in the image?") and the model capability score (MCS; scale 0-10; "How likely do you think the person in the image could pursue a modelling career?"). For each frontal photograph, defined facial measurements and ratios were taken to analyse their relationship with the perception of facial attractiveness and MCS. RESULTS The overall attractiveness rating was 4.3 ± 1.1, while the mean MCS was 3.4 ± 1.1. In young males, there was a significant correlation between attractiveness and the zygoma-mandible angle (ZMA)2 (r= - 0.553; p= 0.011). In young and middle-aged females, MCS was significantly correlated with facial width (FW)1-FW2 ratio (r= 0.475; p= 0.034). For all male individuals, a ZMA1 value of 171.79 degrees (Y= 0.313; p= 0.024) was the most robust cut-off to determine facial attractiveness. The majority of human evaluators (n=62; 51.7%) considered facial implants a potential treatment to improve the patient's facial attractiveness. CONCLUSION This study introduced novel metrics of facial attractiveness, focusing on the facial skeleton. Our findings emphasized the significance of zygomatic measurements and mandibular projections for facial aesthetics, with FI representing a promising surgical approach to optimize facial aesthetics.

[PMID: 38281701 DOI: 10.1016/j.jormas.2024.101788] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 01/19/2024] [Accepted: 01/25/2024] [Indexed: 01/30/2024]
Abstract
The reconstruction of the whole orbitozygomatic framework (OZF) is complex and can be encountered in cases of congenital midface deformity, after tumor ablative surgery and in severe facial trauma. Nowadays, surgeon has a wide range of available techniques that have continually grown over the past years, optimizing the surgical management and the aesthetical outcomes. Among them, the autologous bone graft (ABG) remains one of the most suitable options : ABG is easy to harvest and has optimal biological properties for bone healing. It can be tailored to the patient anatomy thanks to the recent advances in computer-assisted surgery. However, substantial drawbacks remain such as the early resorption of the non-vascularized graft, the need of a donor site and its potential morbidity. Alloplastic reconstruction is another option that can resolve both the resorption issue and the donor site morbidity. Moreover, the 3D-printing technologies also allows the manufacturing of patient specific implants. However, alloplastic materials have a variable success, especially due to the high risk of infection or exposure. Consequently, regenerative medicine is a promising field that aims to find a procedure without the disadvantages of ABG or alloplastic based reconstructions, but displaying similar or even higher success rate. Indeed, recent tissue engineering strategies have demonstrated encouraging results for bone regeneration using natural or synthetic biomaterials, patient cells and synthetic bioactive substances. The objective of this review is to present the etiologies of OZF defect, the available reconstruction procedures as well as the current state of the research.

Abstract
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.

Abstract
Facial feminization surgery (FFS) is often the first procedure requested by patients wishing to undergo gender-affirming surgery. This study aims to evaluate the applicability and effectiveness of deep plane facelifts in FFS. The authors conducted a prospective study that included patients who requested a deep plane facelift as a standalone procedure to achieve a more feminine facial appearance as the only procedure of FFS. These patients underwent deep plane facelifts to achieve a more feminine oval face shape and increased tissue projection of the zygomatic-malar region. To assess the effectiveness of the procedure and patient satisfaction, the Face-Q scales, Face and Neck lift Objective Photo-Numerical Assessment Scale, the Satisfaction With Life Scale, and the Subjective Happiness Scale were applied preoperatively and one year after surgery. Thirty-six patients were included in the study. A statistically significant difference (p < 0.005) was observed between pre and postoperative scores. The repositioning of the malar fat pads increased the malar volume, providing a more oval overall shape of the face, which is typically feminine. No major complications were observed. Despite our encouraging results, new studies with a larger sample of patients are needed to support the benefits of the deep plane facelift as part of FFS to elevate this technique from an ancillary to a routine procedure for patients undergoing gender affirmation surgery.

Abstract
BACKGROUND Alloplastic implantation has become a popular method of chin augmentation. Historically, silicone was the most commonly used implant, but porous materials have grown in favor due to improved fibrovascularization and stability. Nevertheless, it is unclear which implant type has the most favorable complication profile. This systematic review aims to compare the complications of published chin implants and surgical approaches to provide data-driven recommendations for optimizing chin augmentation outcomes. METHODS The PubMed® database was queried on March 14, 2021. We selected studies reporting data on alloplastic chin augmentation excluding additional procedures such as osseous genioplasty, fat grafting, autologous grafting, and fillers. The following complications were extracted from each article: malposition, infection, extrusion, revision, removal, paresthesias, and asymmetry. RESULTS Among the 39 articles analyzed, the year of publication ranged from 1982 to 2020; additionally, 31 were retrospective case series, 5 were retrospective cohort or comparative studies, 2 were case reports, and 1 was a prospective case series. More than 3104 patients were included. Among the 11 implants reported, the 3 implants with the highest number of publications were silicone, high-density porous polyethylene (HDPE), and expanded polytetrafluoroethylene (ePTFE). Silicone demonstrated the lowest rates of paresthesias (0.4%) compared to HDPE (20.1%, P < 0.01) and ePTFE (3.2%, P < 0.05). In contrast, there were no statistically significant differences in rates of implant malposition, infection, extrusion, revision, removal, or asymmetry when stratified by implant type. Various surgical approaches were also documented. Compared with subperiosteal implant placement, the dual-plane technique demonstrated higher rates of implant malposition (2.8% vs 0.5%, P < 0.04), revision (4.7% vs 1.0%, P < 0.001), and removal (4.7% vs 1.1%, P < 0.01), but a lower incidence of paresthesias (1.9% vs. 10.8%, P < 0.01). Compared with extraoral incisions, intraoral incisions resulted in higher rates of implant removal (1.5% vs 0.5%, P < 0.05) but lower rates of asymmetry (0.7% vs 7.5%, P < 0.01). CONCLUSION Silicone, HDPE, and ePTFE had low overall complication rates, demonstrating an acceptable safety profile regardless of implant selection. Surgical approach was found to significantly influence complications. Additional comparative studies on surgical approach while controlling for implant type would be beneficial for optimizing alloplastic chin augmentation practices.

Abstract
Silicone implants are one of the most widely used implants for facial augmentation, especially in the chin, mandibular angle, and malar area, utilizing different surgical approaches. Despite their various advantages, many complications have also been reported, including hematoma, infection, bone resorption, numbness, displacement, and asymmetry. This study aims to evaluate the need for facial-implant fixation and compare and contrast fixated and nonfixated facial silicone implants in different facial sites. A narrative review of the topic of facial-implant stabilization using the PubMed database inclusion criteria included articles that discussed the topic of facial implants, were published in English, and included critical information such as the location of the implant, type of stabilization, follow-up periods, and complications. A total of 11 studies were included. Of these, two were prospective clinical studies, three were case series, and the remaining six were retrospective clinical studies. The studies were published between 1995 and 2018. The sample size varied from 2 to 601 cases. Stabilization includes suturing, monocortical screws, or no stabilization. Complications were reported in most of these studies, including asymmetry, bone resorption or erosion, displacement, dissatisfaction, edema, hematoma, infection, mucosal irritation, pain, and paresthesia. The follow-up period ranged from one month to 17 years. Despite the varied settings of these studies, silicone facial implant complications were reported in both fixated and nonfixated implants, with a lack of significant differences between fixated and nonfixated facial silicone implants regarding the method of fixation.

Abstract
Facial cosmetic implants are utilized for definition enhancements in the malar, mandibular, and nasal regions. Though these implants are safe in the majority of patients, notable complications such as implant malpositioning may be seen. More rare but serious complications such as infection, abscess, and intrasinus migration may also occur, such as in this case reported on a 69-year-old female with a history of bilateral malar silicone implants. Imaging findings on this patient, whom initially presented with complaints of erythema and edema in the left malar region, were notable for edema and soft tissue signs of infection around a well-visualized crescent shaped maxillary implant. Penetration of the implant into the left maxillary sinus was also noted. Diagnostic imaging played a key role in determining the cause and severity of this patient's condition. Thus, the case reported is with an aim to familiarize radiologists with identifying and interpreting the complications of malar cosmetic implants on diagnostic imaging.

Abstract
PURPOSE Despite maxillo-malar osteotomies having been discarded in the most recent literature, in the setting of orthognathic surgery they provide several advantages for middle third augmentation. This paper reintroduces maxillo-malar osteotomies as an effective method to increase volume of midfacial region in combination with contemporary technology, including piezosurgery, virtual surgical planning, and navigation. MATERIAL AND METHODS Eighteen patients with midface hypoplasia were included in this study and underwent orthognathic surgery with maxillo-malar osteotomies. All patients underwent the same workflow: virtual design of maxillo-malar osteotomies, surgery with navigation-assisted piezoelectric osteotomies, and computerized morphometric analysis. RESULTS Simulated maxillo-malar osteotomies were successfully replicated in the operating room, as shown by accuracy evaluation performed using three-dimensional analysis. In long-term follow-up period, no permanent complications were assessed. Superimposition between postoperative and preoperative CBCTs revealed that the soft tissue area influenced by the underlying skeletal movement was comparable for all cases. CONCLUSIONS Virtual surgical planning, navigation, and piezosurgery are today indispensable tools to perform maxillo-malar osteotomies safely and accurately. We suggest incorporating such osteotomies in the surgeon's armamentarium for patients with severe midfacial hypoplasia as they offer an integrated solution to restore functionality and aesthetics.

Abstract
The paranasal area is closely associated with midfacial esthetics. However, there is no special technique available to achieve ideal esthetics paranasal restoration. The present study aims to apply the 3D printed PolyEtherEtherKetone (PEEK) implants as an innovative solution for esthetic paranasal reconstruction. On the basis of the CT scan, the patient-specific PEEK implant and a surgical guiding plate were manufactured aided by a computer. Preoperative and postoperative CBCT data were utilized to evaluate esthetic outcomes. The average follow-up period was 13 months. All patients' wounds healed by first intention. The statistical analysis of preoperative and postoperative esthetic indices revealed light levels of postoperative paranasal depression (P<0.001) and the wrinkle severity rating scale for nasolabial folds (P<0.001). Moreover, the nasolabial angle increased (P<0.05). The established 3D-printing PEEK implanted prosthesis can individually correct the depressed deformity of the paranasal region, and achieve favorable clinical esthetic outcomes.

Abstract
PURPOSE OF REVIEW To examine the recent literature on aesthetic alloplastic malar implants. RECENT FINDINGS Alloplastic implantation is heavily favored in the oromaxillofacial literature. Recent articles have examined porous polyethylene and silicone implantation. Overall patient satisfaction is high and complications are low. Outcomes are likely comparable with alternative modalities to rejuvenate the face in the appropriate hands. SUMMARY Alloplastic implantation continues to be a reliable tool for malar augmentation.

Evaluation and treatment of facial feminization surgery: part II. lips, midface, mandible, chin, and laryngeal prominence. Arch Plast Surg 2022; 49:5-11. [PMID: 35086301 PMCID: PMC8795653 DOI: 10.5999/aps.2021.01956] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 12/01/2021] [Indexed: 11/08/2022] Open
Abstract
Facial feminization surgery (FFS) refers to a set of procedures aimed at altering the features of a masculine face to achieve a more feminine appearance. In the second part of this twopart series, assessment and operations involving the midface, mandible, and chin, as well as soft tissue modification of the nasolabial complex and chondrolaryngoplasty, are discussed. Finally, we provide a review of the literature on patient-reported outcomes in this population following FFS and suggest a path forward to optimize care for FFS patients.

Radiographic Features of Facial Cosmetic Material: Report of Two Cases. Case Rep Dent 2021; 2021:7308636. [PMID: 34631177 PMCID: PMC8497133 DOI: 10.1155/2021/7308636] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Accepted: 09/02/2021] [Indexed: 11/18/2022] Open
Abstract
Recently, the use of noninvasive facial cosmetic procedures has been widely disseminated. In the face, cosmetic fillers, threads, and implants are used to reduce or delay the effects of aging or adjust facial defects caused by trauma or disease. The dentist or dental specialist may encounter these materials in the radiographic images of their patients. There are few reports in the dental literature describing the radiographic appearance of some materials along with the diseases they mimic. As the procedures and materials advance and evolve, dentists and dental specialists must be aware of their radiographic appearance to avoid errors in diagnosis. This is a report of two cases that include panoramic radiography and CBCT scan. Among these cases, there is an unusual appearance of a cosmetic filler due to a subperiosteal injection method. Moreover, it will discuss common types of cosmetic materials used in the face and their imaginological appearance. This is the key to dentists and dental specialists due to increasing use of facial cosmetic materials and a parallel increase in the use of cone beam CT and chances to encounter such findings.

Abstract
Genioplasty is a useful technique employed for both aesthetic and, in the case of obstructive sleep apnea, functional purposes. Mandibular implants similarly represent a powerful tool in the facial surgeons armamentarium. Herein, we review relevant anatomy, patient evaluation, and various techniques employing both alloplastic augmentation and osseous modification of the mandible.

Abstract
Implant-associated infections (IAIs) are among the most intractable and costly complications in implant surgery. They can lead to surgery failure, a high economic burden, and a decrease in patient quality of life. This manuscript is devoted to introducing current antimicrobial strategies for additively manufactured (AM) titanium (Ti) implants and fostering a better understanding in order to pave the way for potential modern high-throughput technologies. Most bactericidal strategies rely on implant structure design and surface modification. By means of rational structural design, the performance of AM Ti implants can be improved by maintaining a favorable balance between the mechanical, osteogenic, and antibacterial properties. This subject becomes even more important when working with complex geometries; therefore, it is necessary to select appropriate surface modification techniques, including both topological and chemical modification. Antibacterial active metal and antibiotic coatings are among the most commonly used chemical modifications in AM Ti implants. These surface modifications can successfully inhibit bacterial adhesion and biofilm formation, and bacterial apoptosis, leading to improved antibacterial properties. As a result of certain issues such as drug resistance and cytotoxicity, the development of novel and alternative antimicrobial strategies is urgently required. In this regard, the present review paper provides insights into the enhancement of bactericidal properties in AM Ti implants.
