Esthetic Surgery of the Chin in Cis- and Transgender Patients-Application of T-Genioplasty vs. Single-Piece Segment Lateralization.

Background and Objectives: Correction of lower face asymmetry still remains challenging in maxillofacial surgery. This report describes techniques for the lateral transposition of the symphyseal segment to restore lower face symmetry while maintaining gender-related features in cis- and transgender patients. Materials and Methods: A retrospective review of medical records of 31 patients who attended for esthetic corrective surgery after orthodontic camouflage or orthognathic treatment, or during facial feminization of the lower face between June 2021 and June 2023 was performed. Result: All patients underwent lateralization genioplasty (with or without advancement or setback), either with or without narrowing T-osteotomy supplemented with necessary procedures in order to obtain proper facial balance and desired esthetical effects, such as bichectomy, liposuction, and face and neck lift. The mean asymmetry of the chin was 5.15 mm and was surgically corrected either by single segment lateralization or T-shape narrowing genioplasty depending on the gender and esthetical requirements. No complications were reported. Conclusions: Lateral shift genioplasty serves as a powerful tool in primary and secondary corrective surgery for lower face asymmetry that maintains gender-specific facial features. It may serve either as an additive to orthodontic camouflage or a way to correct previous orthognathic surgery pitfalls. The surgeon performing esthetic genioplasty associated with gender-specific expectations must be trained in facelift and facial liposculpting techniques in order to provide the best results and properly choose the right procedures for the right patients.

A systematic review and meta-analysis of the surgical outcomes in patients with osteochondroma of mandibular condyle.

Many options exist in the diagnosis and management of condylar osteochondroma. The purpose of this study was to provide a congregate information concerning treatment of the osteochondroma involving the mandibular condyle. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and Cochrane database until February 2022. Twenty-seven studies were included for the final review. The review included 439 patients who underwent surgical management for mandibular condylar osteochondroma. The position of osteochondroma was mentioned in 13 studies. Preauricular, retromandibular, endaural, submandibular, transzygomatic, and intraoral approaches were used for approaching the tumor. Surgical techniques included resection, conservative condylectomy, and total condylectomy. Concomitant orthognathic surgery was performed along with tumor resection in 19 studies. In the entire review, the recurrence rate was 0.22% (1/439). The results of the meta-analysis showed that 2 studies reported significant malocclusion events after surgical therapy. Total joint replacement after tumor resection has a higher improvement in maximal mouth opening (8 mm) compared with vertical ramus osteotomy and no reconstruction groups, which have similar improvements (6 mm). The mainstay of treatment of osteochondroma is surgical excision either as condylectomy or conservative condylectomy. Among the various reconstruction modalities, total joint replacement showed better improvement in mouth opening. Adjunct procedures like orthodontic and orthognathic surgery have an important role in holistic management of severe cases. The treating surgeon must choose the surgical procedures in a pragmatic way.

Using an expanded scalp flap without fascial flap harvest or skin grafting for total auricular reconstruction in hemifacial microsomia with low hairline.

BACKGROUND: Total auricular reconstruction for hemifacial microsomia patients with extremely low hairline is a tough challenge in plastic surgery. In this work, a brand new technique using a singer expanded scalp flap without skin graft and combined with intense pulse light treatments (IPLT) for ear reconstruction is described in this special population. METHODS: From January 2015 to April 2019, 41 hemifacial macrosomia (HFM) patients with 70-100% low hairline were enrolled in our study. Operative treatment was performed in 3 stages: 1. Expander insertion and inflation; 2. Expander removal, costal cartilage framework fabrication and auricular reconstruction; 3. Tragus reconstruction and reconstructed auricle refinement. Several IPLTs were performed every 45 days until local area become hairless during the whole course. The first IPLT could be executed either before all the operations or during the expansion period. The flap was treated with M22 system using a filter of 695-1200 nm. Follow up ranged from 10 months to 4 years. RESULTS: During follow-up, 90.2% patients were surveyed as satisfied with the outcome, especially in the aspects of minimal scars, natural matched color and clear contour of the reconstructed ear. No serious complications happened. Patients starting the IPLT during the expansion period required less treatment times of depilation (p < 0.05). CONCLUSION: Auricular reconstruction using a single expanded scalp flap combined with intense pulse light depilation is a safe, effective and less invasive technique for hemifacial microsomia with extremely low hairline, and providing highly satisfying results. Initialing the IPLD during the expansion period is recommended. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

La ortodoncia y la cirugía ortognática como aliadas en el tratamiento / Orthodontics and orthognathic surgery as treatment allied

¿Qué es la estética? Es más que un concepto frívolo. Tiene que ver con la armonía facial, la autoestima, la autoimagen, la percepción de belleza. Es un concepto que involucra al individuo en su totalidad, en su ser, que va más allá de frivolidad estética. Muchos pacientes que vienen a la consulta no expresan inicialmente su real demanda. Expresan problemas funcionales, pero su real preocupación, en la mayor parte de los casos, es estética. Pueden manifestar que no pueden comer bien, masticar un alimento o que no respiran bien o sesean, pero su motivación principal es estética y tiene que ver con su propia autoestima. Las funciones de respiración, deglución, fonación, masticación, oclusión deben estar entre los objetivos a conservarse o restituirse por parte del especialista, pero el tratamiento sería un fracaso si no atendemos la demanda, a veces no bien explicitada, por el paciente y que responde a su profunda necesidad real. Para la OMS, la salud puede definirse como el estado completo de bienestar físico, mental y social. Nuestro objetivo, como agentes de salud, será poder satisfacer la demanda explícita o encubierta con la mayor estética y la mayor funcionalidad (AU)

What is aesthetics? It is more than a frivolous concept. It has to do with facial harmony, self-esteem, self-image, the perception of beauty. It is a concept, which involves the individual as a whole, in his being, which goes beyond aesthetic frivolity. Many patients who come to the office do not initially express their real demand. They express functional problems, but their real concern, in most cases, is aesthetic. They may state that they cannot eat well, chew a food or that they do not breathe well or sedate, but their main motivation is aesthetic and has to do with their own self-esteem. The functions of breathing, swallowing, phonation, chewing, occlusion should be among the objectives to be retained or restored by the specialist, but the treatment would be a failure if we do not meet the demand sometimes not well explained by the patient and responding to their Deep real need. For WHO, health can be defined as the complete state of physical, mental and social well-being. Our goal, as health agents, will be to be able to meet the explicit or covert demand with the greatest aesthetics and functionality (AU)

La artritis reumatoidea juvenil y su influencia en la alteración de desarrollo de la mandíbula / Juvenile rheumatoid arthritis and its influence on the alteration of jaw development

La artritis reumatoidea juvenil (ARJ) es una enfermedad inflamatoria autoinmune que se presenta en niños menores de 16 años. Es de curso crónico, etiología desconocida, y afecta sobre todo las articulaciones, como la temporomandibular (ATM). El daño de la ATM puede ocasionar: alteraciones en el crecimiento facial (micrognatia), maloclusión clase II, mordida abierta anterior, desviaciones laterales, erosiones óseas, destrucción del cón-dilo, oclusión disfuncional y alteración de la estética facial, entre otras consecuencias. La posición oclusal neurofisiológica lograda por medio de elementos electrónicos, como el Transcutaneus Electrical Neural Stimulation (TENS), y mantenida por el Dispositivo Intaroral (DIO) podría posibilitar la remodelación de la cabeza del cóndilo, en pacientes en crecimiento, en los que la enfermedad se halla controlada, regulando así también la sintomatología dolorosa...

Rehabilitation and functional recovery after masseteric-facial nerve anastomosis.

BACKGROUND: After masseteric-facial nerve (V-VII) anastomosis, a new neurological circuit oversees the facial muscles and patients should learn to activate the facial movements using the masseteric function. AIM: To monitor the rehabilitative protocol of facial muscles activation through teeth clenching and to assess the clinical evolution after V-VII anastomosis in terms of facial symmetry and functional recovery. DESIGN: Case series. SETTING: Outpatients clinic. POPULATION: Eleven patients undergone V-VII anastomosis for complete unilateral facial palsy. METHODS: After surgery, patients underwent a needle electromyography (EMG) and a rehabilitative training with mirror feedback to learn how to reach the symmetry at rest and during facial movements through teeth clenching. The rehabilitative protocol at the first clinical evaluation has been monitored through the Italian version of Sunnybrook Facial Grading System (SFGS) and the Software Facial Assessment by Computer Evaluation (FACE). Functional limitations and quality of life have been evaluated using the Italian version of Facial Disability Index (FDI). The clinical evolution at 18 months was evaluated with EMG, SFGS, biting evaluation and FDI. RESULTS: At the first clinical evaluation after reinnervation, through teeth clenching patients displayed an improvement of symmetry at rest, symmetry of voluntary movement, symmetry of smile and composite score of SFGS. Objective measurement of facial structures with FACE system demonstrated an improvement of symmetry at rest and during smile through teeth clenching. At 18 months patients displayed a good reinnervation with a further improvement of SFGS scores and reduction of functional disability. No biting deficit has been observed. CONCLUSIONS: After V-VII anastomosis, at the first rehabilitative visit, patients learn to activate the reinnervated facial muscles through teeth clenching. Eighteen months after the anastomosis, patients display a further improvement of voluntary control on facial symmetry and smile and a reduction of disability. CLINICAL REHABILITATION IMPACT: Our study illustrates the rehabilitative protocol after V-VII anastomosis and analyzes the clinical evolution after this intervention in terms of recovery of facial symmetry and reduction of disability. This will be instrumental to standardize the rehabilitative protocol among different centers and to choose the best patient-tailored surgical approach for subjects affected by complete facial palsy.

Frontal augmentation as an adjunct to orthognathic or facial contouring surgery / 대한악안면성형재건외과학회지

BACKGROUND: The dimensions and shape of the forehead determine the esthetics of the upper third of the face. Korean young people consider a broad and smooth, rounded forehead more attractive. As a result, frontal augmentation becomes more popular in patients with dentofacial deformities. Various surgical procedures and materials have been used in frontal augmentation surgery, with associated advantages and disadvantages. Silicone is a good candidate for frontal augmentation. The author presents two cases of esthetic frontal augmentation with a prefabricated silicone implant in female patients with dentofacial deformities. CASE PRESENTATION: In case 1, a 24-year-old female patient underwent frontal augmentation surgery with simultaneous maxillomandibular and zygomatic osteotomies to correct facial asymmetry. A silicone implant was fabricated preoperatively using a positive template stone mold of her forehead. In case 2, a 23-year-old female patient underwent total facial contouring surgery including frontal augmentation for improved facial esthetics. A computed tomography (CT)-guided rapid prototype (RP) model was used to make the silicone implants. The operative procedure was safe and simple, and the silicone implants were reliable for a larger degree of frontal augmentation. Six months later, both patients had recovered from the surgery and were satisfied with their frontal shape and projection. CONCLUSIONS: Frontal augmentation with silicone implants can be an effective adjuvant strategy to improve facial esthetics in patients with a flat and narrow forehead who undergo orthognathic reconstruction or total facial contouring surgery.

Influencia del patrón morfogenético en el crecimiento y desarrollo / Influence of morphogenetic pattern on growth and development

Se plantean dos situaciones clínicas de pacientes adultos, hermanos, que presentan la misma maloclusión (Clase III con desviación mandibular hacia la izquierda), distinto sexo y biotipos faciales diferentes. En ellos queda de manifiesto en qué manera el patrón facial de cada individuo es determinante en la génesis de una maloclusión, teniendo una influencia directa en el pronóstico y plan de tratamiento. Uno de los casos se resolvió ortodóncicamente, con un tratamiento de compensación y extracción asimétrica del elemento 44, al tiempo que en el otro se efectuó un tratamiento ortodóncico-quirúrgico.

One-stage treatment to osteochondroma of the coronoid process and secondary facial asymmetry with coronoidectomy and reduction malarplasty: a case report and literature review.

PURPOSE: This study summarizes the literature concerning osteochondroma of the mandibular coronoid process and presents a case of 1-stage treatment for this condition and concomitant facial asymmetry. MATERIALS AND METHODS: A 20-year-old man presented with osteochondroma of the mandibular coronoid process. Radiologic images showed a mushroom-shaped coronoid growth inside the zygomatic arch with outward expansion. Coronoidectomy and reduction malarplasty were performed in 1 stage. The literature on osteochondroma of the mandibular coronoid process since 1943 was reviewed concerning etiology, pathogenesis, clinical characteristics, diagnosis, and treatment. RESULTS: At 20-month follow-up, the patient achieved markedly improved joint function and a symmetric facial appearance after excision of the osteochondroma. CONCLUSION: Coronoidectomy combined with simultaneous reduction malarplasty could be an alternative and promising method to treat osteochondroma of the coronoid process with secondary facial asymmetry.

Skeletal Class III and anterior open bite treatment with different retention protocols: a report of three cases.

The treatment of skeletal class III and anterior open bite can be unstable and orthodontists frequently observe relapse. Here, we report on the management of three patients with skeletal class III profiles and open bites treated by orthodontic camouflage. Each received a retention protocol involving the use of two separate appliances during the night and day accompanied by myofunctional therapy. Long-term follow-up revealed a stable outcome.

[Dentofacial Orthopedics to treat facial asymmetries before six years of age. How to balance craniofacial growth and enhance temporomandibular function]. / Traiter orthopédiquement les asymétries avant six ans ou comment symétriser la croissance cranio-faciale et optimiser le fonctionnement temporo-mandibulaire.

Minor facial asymmetries that can be detected in newborn infants indicate that facial growth for this child will also be asymmetric. When practitioners observe a displacement of the mandible in temporary dentition it probably indicates the presence of asymmetric masticatory function and they should look for an inter-temporal axial asymmetry by tracing cutaneous landmarks in the vicinity of the external ears. If they find the possible presence of asymmetric remodeling of glenoid fossas, they have to anticipate future temporo-mandibular disorders. By using a measurement grid (Orthogrille type) placed on the teeth of the upper plaster cast, they can assess sagittal and transverse status of the temporary teeth. If indicated, they can use acrylic plates fitted with sectional distalizing or expansion screws designed for full or partial arch correction. They can also modify the upper occlusal plane inclination by using acrylic bite blocks that keep all of the teeth from occluding and thus allow the displaced mandible to return to symmetrical movements during mastication and at the same time allow the temporal bones to remodel symmetrically. Finally, they can re-center the two dental arches and their midlines with a Frankel re-centering device that will also restore harmony to respiratory and vocalization functions. Thanks to this type of orthopedic treatment carried out for patients before they reach the age of six the asymmetric direction of their facial growth will become normal and the functioning of their temporo-mandibular joints will become optimal.

Lasers and optical technologies in facial plastic surgery.

Lasers and optical technologies play a significant role in aesthetic and reconstructive surgery. The unique ability of optical technologies to target specific structures and layers in tissues to effect chemical, mechanical, or thermal changes makes them a powerful tool in cutaneous rejuvenation, hair removal, fat removal, and treatment of vascular lesions such as port-wine stains, among many other procedures. With the development of adjunct techniques such as epidermal cooling, lasers and optical technologies have become more versatile and safe. The constant improvement of existing applications and the emergence of novel applications such as photodynamic therapy, nanoparticles, spectroscopy, and noninvasive imaging continue to revolutionize aesthetic medicine by offering a minimally invasive alternative to traditional surgery. In the future, therapies will be based on individualized, maximum, safe radiant exposure to deliver optimal dosimetry. Lasers and optical technologies are headed toward safer, easier, more quantifiable, and more individualized therapy.

[The bronze head of Seuthes III. A maxillofacial surgery case from antiquity]. / Der Kopf der Bronzestatue des thrakischen Königs Seuthes III. Ein Kiefer- und Gesichtschirurgischer Fall aus der Antike.

The authors had the opportunity to visit the tumulus of Golijama Kosmatka in todays central Bulgaria and the there found burial artefacts of Seuthes III., a Thracian King who lived in the 4th-3rd century BC. The beautiful bronze head of the king found in front of the burial site shows the typical sequelae of a dislocated lateral mid face fracture in all details. These findings do fit and also confirm the troublesome times this local king went through after the death of Alexander the Great.
