Matrixmidface Preformed Orbital Implants for Three-Dimensional Reconstruction of Orbital Floor and Medial Wall Fractures: A Prospective Clinical Study.

Prospective Interventional study. To evaluate the efficiency of Matrixmidface preformed Orbital plates for three-dimensional reconstruction of orbital floor and medial wall fractures. This prospective institutional clinical study was conducted on a group of 14 patients who underwent repair of orbital floor and medial wall fracture defects using Matrixmidface Preformed Orbital plates and open reduction and internal fixation of associated fractures. The following parameters were studied preoperative and postoperative enophthalmos, hypoglobus, orbital volume; correction of diplopia, intraoperative and postoperative complications. All 14 patients were males aged between 19 and 42years. The most common mode of injury was found to be road traffic accidents (RTAs) followed by self-fall and trauma at workplace. Orbital fractures were associated with other concomitant maxillofacial fractures in 12 patients (85.7%) while 2 patients (14.3%) had pure blowout fractures. Significant improvement of enophthalmos was noted from preoperative period to 1 week, 6weeks, and 6 months postoperatively (P value .02, .01, and .01, respectively). Out of 11 patients with preoperative hypoglobus, 5 patients (45.45%) had persistent hypoglobus in the immediate postoperative period which reduced to 4 patients (36.36%) at 6 weeks postoperatively (p value .00). The postoperative orbital volume of fractured side ranged from 20.3cm3 to 26.76cm3 with a mean of 23.50cm3 ± 1.74. The mean difference between the volumes of the repaired and uninjured sides was found to be .27cm3 ± .39 (P value .02) denoting that the reconstruction of the orbit closely approximated that of the uninjured side. The Matrixmidface Preformed Orbital plate provides exceptional reconstruction of the orbital blowout fracture defects and ensures satisfactory results clinically and radiographically. The plate ensures an approximate recreation of topographical anatomy of the orbit and adequately restores the orbital volume. It provides adequate correction of asymmetry, hypoglobus, enophthalmos and attempts to restore eye movements, without causing any significant postoperative complication.

Hyaluronic Acid in Facial Rehabilitation—A Narrative Review

Background: Hyaluronic acid fillers (HAF) are a versatile tool in esthetic medicine. They also have a potential for medical indications including facial rehabilitation. Materials and methods: We performed a literature search on PUBMED and Google Scholar until December 2022. Clinical trials, clinical studies, review articles, systematic reviews, meta-analyses, case series, and case reports were considered for review. Keywords “facial rehabilitation”, “acne scars”, “traumatic scars”, “oral restoration”, “facial lipoatrophy”, “facial asymmetry”, “periocular correction”, “nasal obstruction”, “ear lobe restoration”, “morphea”, AND “hyaluronic acid filler” were used to select articles. Results: We prepared a narrative review on the use of HAF for correction of facial asymmetry and asymmetric lips, improvement of different types of scars, improvement of the jaw line, improvement of ear lobes, periocular and oral restoration, and the treatment of nasal obstruction and morphea en coub de sabre. The amount of HA used in these indications is often less than 1 mL. The bolus technique, fanning, and dual-plane injections can be utilized for treatment. Duration of clinical effects depends upon the anatomical region and is usually maintained between 2 months and 2 years. Adverse events are often mild and temporary. Vascular occlusion is a severe adverse event, but it has not been reported yet for these medical indications. Repeated injections are recommended to obtain a longer-lasting improvement. In cases of morphea, only stable and non-inflammatory plaques should be treated. The advantage of HAF compared to permanent and semipermanent fillers is the availability of hyaluronidase for rapid removal of filler material and to revise overcorrection. Conclusions: HAF play an auxiliary role in facial rehabilitation. Knowledge of filler qualities, anatomy, and underlying diagnoses is important for their safe application. More prospective controlled trials are necessary to improve evidence.

Preoperative Anatomical Variables Affecting the Outcome of Surgical Correction in Class III Face Asymmetry

Objective: The study investigated the preoperative anatomical variables that affect the outcome of surgical correction in patients with Class III facial asymmetry. Methods: The study recruited 37 consecutive patients with facial asymmetry who had 2-jaw orthognathic surgery. They were divided into two groups based on the surgical outcome: symmetrical (S group) or asymmetrical (A group), according to the asymmetry index. The CBCT images were obtained before surgery (T0) and after debond (T1). The 3D dentofacial measurements were compared between groups S and A by the Mann–Whitney test. Spearman correlation analysis was performed to examine the relationship of all dentoskeletal variables in T0 with the facial symmetry outcome. Results: Significant between-group differences were observed in preoperative time, including maxillary anterior occlusal canting, maxillary posterior occlusal canting, the gonion–Frankfort horizontal plane (FHP) distance, the mandibular ramus axis–FHP distances, and sagittal and transverse of condyle position. Conclusions: For patients with severe skeletal Class III asymmetry, preoperative anatomical variables, particularly preoperative “roll” and “yaw” discrepancies and anatomical limitations of the mandible, should be considered for favorable asymmetry correction. Based on the anatomic variables that affect the outcomes of facial asymmetry correction, prognosis and treatment limitation could be predicted before treatment.

3D Volume Assessment as an Objective Tool in Breast Asymmetry Management.

This study was conducted between November 2017 and September 2021 on 20 female patients seeking breast asymmetry correction at Kasr El-Ainy Hospital. All patients had volumetric breast assessment using a three-dimensional (3D) imaging system (3D LifeViz, Quantificare system), and MRI breast volumetry was done preoperatively in all patients. The patients were managed with different single-stage surgical procedures depending on the objective assessment of the volume differences between their breasts. Breast volume assessment using the 3D camera was done preoperatively and postoperatively. The preoperative mean volume difference was 159.45 cm3, and the postoperative mean difference was 16.75 cm3 with an overall reduction in mean volume difference of 89.5%. Comparing the 3D camera and MRI in assessing breast volume difference showed no statistical significance. The 3D technology is a useful objective tool to augment the surgeon's experience. It helped achieve an 84.57% reduction in volume difference in managing breast asymmetry with a single-stage procedure.

Minimally invasive spine surgery strategy for congenital cervicothoracic scoliosis in children: Less blood loss and shortened segmental fusions/fewer pedical screws.

To explore the feasibility of a minimally invasive spine surgery strategy for congenital cervicothoracic scoliosis. From April 2022 to August 2022 in the hospital, three patients with torticollis and/or shoulder imbalance due to a cervicothoracic hemivertebra were performed on by hemivertebra resection and short fusion of the adjacent vertebrae. Resection was operated by a posterior approach. The average age of three patients of surgery was 8 years 2 months and the mean follow-up period was 6 months. Radiographic assessments and cosmetic outcomes were documented on changes in measurements of segmental scoliosis, neck tilt, head shift, shoulder balance, and sagittal profiles. The mean operating time of the procedure was 283 min and the instrumentation density was 1.5 pedicle screws per vertebra. The mean estimated blood loss was 257 ml, which was 20% less than the data described in various literatures. The mean segmental Cobb angle at the cervicothoracic deformity was 35.9° before surgery, 20.7° after surgery, and 16.3° at the latest follow-up, with a correction rate of 54.59%. Neck tilt decreased from 17.3° before surgery to 14.3° after surgery, and 11.7° at the latest follow-up, with a correction rate of 32.37%. T1 tilt improved from 16.5° before surgery to 12.9° after surgery, and 7.6° at the latest follow-up, with a correction rate of 53.94%. The clavicle angle improved from 4.8° before surgery to 3.1° after surgery, and 1.9° at the latest follow-up, with a correction rate of 60.42%. Head shift improved from 21.4 mm before surgery to 9.2 mm after surgery, and 12.3 mm at the latest follow-up, with a correction rate of 42.52%. The correction of torticollis and shoulder asymmetry was achieved in all cases. Minimally invasive spine surgery strategy may be an option for congenital cervicothoracic scoliosis. A good correction of cervicothoracic dissymmetry is achieved, accompanied by fewer pedicle screws and less blood loss. By deliberate operation in young kids, surgical intervention for severe compensatory curves can be prevented.

Integrated Approaches for Reconstruction of Facial Paralysis.

Facial paralysis can affect periorbital muscles, oral competence, and facial expressions with significant facial deformities, which could occur in either children or adults with variable severity, duration, and degree of recovery. The present study was aimed to delineate treatment plans for facial paralysis with different clinical scenarios and to report the results of these patients. Patients were grouped according to different presentations as follows: (1) facial paralysis with incomplete recovery; (2) young patients of facial paralysis without recovery; (3) senile patients of facial palsy without recovery; (4) combined facial palsy with mandibular deficiency, vascularized bone reconstruction for mandible with (a) subsequent muscle transfer or (b) simultaneous sling operation or (c) simultaneous facial nerve exploration and cross nerve grafting; (5) palsy of frontal branch of facial nerve; (6) palsy of zygomatic-buccal branch of facial nerve; (7) palsy of marginal mandibular branch of facial nerve; (8) partial recovery with dyskinesia; and (9) facial paralysis with dynamic asymmetry and muscle atrophy. According to clinical scenarios, different treatment plans were provided, and clinical outcomes were evaluated and presented. All patient groups achieved fair or satisfactory outcomes. Revisions using sling procedures, botulinum toxin injection, and filler or fat graft as supplement further refined the ultimate outcomes. For reconstruction of facial paralysis, individualized integrated treatment plans are mandatory according to the presentation and condition of the patient. Comprehensive considerations and strategic solutions for the existing disabilities have been appreciated by the patients. The least numbers of operations with considerate correction of asymmetry were the major concerns of the patients.

Aesthetic Genioplasty Based on Strategic Categorization.

Genioplasty is a popular procedure used for lower facial contour correction. Various osteotomy techniques enable us to perform advancement, setback, reduction, or narrowing procedures. Computed tomographic images facilitate preoperative planning in detail. The authors used a novel planning method based on strategic categorization. The analytic results are described. This retrospective study reviewed 208 patients who underwent genioplasty procedures for facial contouring from October of 2015 to April of 2020. During preoperative evaluation of the mandible, the operative procedure selected was one of three types: (1) horizontal segment osteotomy, (2) vertical and horizontal segment osteotomy, and (3) bone graft after repositioning. Adequate osteotomies were followed by rigid fixation using a titanium plate and screws. The follow-up period ranged from 8 to 24 months (average, 17 months). The results were assessed based on medical records, photographs, and facial bone computed tomographic images. Overall, the patients were satisfied with the outcomes and had responder-based improvement in lower facial contour and balance. Chin point deviations were noted in 176 cases; left-side deviation ( n = 135) was more frequent than right-side deviation ( n = 41). Strategic osteotomies based on precise measurements led to correction of asymmetries. Temporary partial sensory losses reported in 12 cases resolved within an average of 6 months after surgery. Each patient's chief complaint and bony structures should be carefully evaluated before genioplasty procedures are performed. During the operation, meticulous osteotomy, precise movement, and rigid fixation are necessary. The strategic process used for genioplasty resulted in aesthetic balance and predictable outcomes.

A Simple and Effective Intraoperative Technique for Correction of Severe Congenital Breast Asymmetry.

One severe type of congenital breast asymmetry, with a hypoplastic breast on one side and a hyperplastic breast on the other side, has been recognized in the author's practice. Although breast augmentation, mastopexy, and breast reduction used separately or in combination are the most common procedures performed to correct congenital asymmetrical breasts, an effective approach for the correction of such a congenital breast asymmetry has not been established in the literature. In this article, a simple and effective intraoperative approach is described for correction of severe congenital breast asymmetry. Breast augmentation with an implant for the hypoplastic side and mastopexy or small breast reduction for the hyperplastic side were performed. Symmetry was achieved intraoperatively by an implant for breast augmentation on the hypoplastic side and mastopexy or small reduction, determined by a tailor-tacking technique, on the hyperplastic side. In the past 2 years, a total of 4 patients with severe congenital breast asymmetry was operated on by the author with this established approach. All patients were pleased about their symmetry and cosmetic outcome without any surgical complications. The resulted breast scars are minimal and well tolerated by patients. No revision or subsequent surgery has even been needed during follow-op. Correction of severe congenital breast asymmetry is not an easy task and can be difficult. This simple and effective intraoperative approach provides a relatively easy and logical way as a 1-stage procedure for this subgroup of patients with symmetrical and cosmetically pleasing outcome.

Tip Plasty: A New Modified Vertical Dome Division. “How I Do It?”

This manuscript aimed to report a new vertical dome division technique for the correction of different common nasal tip deformities. This technique is a novel approach and was never reported in the literature to the best of our knowledge. The technique was performed using an open approach on 337 patients presenting with a combination of different nasal tip deformities: overprojected nasal tips, drooping tips, asymmetical tips and wide domal arches. The included patients were operated on between 2012 and 2018, with a follow-up period of at least 1 year. A detailed description of the surgical steps used is provided. Surgery outcomes were predominately positive, with unsatisfactory results obtained only in 11 of the 212 included patients (125 patients were excluded from the study due to inadequate or no follow-up). Satisfactory results and minor complications were detected following this procedure. In conclusion the presented technique is an easy and effective method for the narrowing, uprotation, and deprojection of nasal tips as well as the correction of tip asymmetries mainly in thick-skin patients, with a low complication rate.

Anthropometric Measurements and Analysis for Objective Assessment of Gynecomastia Surgery Results.

Gynecomastia surgery is one of the most common aesthetic procedures in males. There is a lack of objective analytical parameters to judge outcomes. In this study, the authors aim to introduce novel anthropometric measurements and analysis techniques for the objective assessment of surgical outcomes based on specific aesthetic targets. To introduce quantification of gynecomastia surgery outcomes and compare the results among the different grades of gynecomastia. A total of 192 patients with gynecomastia were included. The patient cases were grouped according to grades and a set of anthropometric measurements were taken both before the operation and 6 months postoperatively. Liposuction and glandular excision were done through minimal incisions in all grades of gynecomastia, with the addition of ultrasound and nipple areola complex (NAC) lifting plaster in selected Grade 3 and all Grade 4 cases. A statistically significant improvement in the perimeter of the triangular relationship of sternal notch and nipples, the elevation of the NAC, the reduction of the area of the NAC, and the correction of asymmetry of the chest were seen in all grades of gynecomastia, with increased differences in higher grades. A systematic objective analysis of the specific aesthetic targets helps to reliably compare results in a standard way and for carrying out improvisation of surgeons' techniques. Meanwhile, this approach helps identifying the need for customization, eventually providing symmetric and aesthetically pleasing surgical results.

Orthodontic considerations for patients presenting with Goldenhar Syndrome: A long-term case report

Abstract Introduction The correction of facial asymmetry in patients presenting with Goldenhar Syndrome can be challenging due to the complexity of the orthodontic and surgical procedures required, the psychosocial considerations of the patient and the risk of relapse. Materials and methods A Caucasian male with Goldenhar Syndrome originally presented at age 8.2 years with concerns relating to a poor bite. He had previously undertaken surgery for the removal of pre-auricular skin tags on the right side. With ongoing skeletal growth, the facial asymmetry became more obvious and caused the patient to become socially withdrawn. Multidisciplinary treatment involving orthodontics and orthognathic surgery to correct the mandibular asymmetry was delayed until facial growth had slowed. The correction involved the use of an asymmetrical bilateral sagittal split osteotomy and an advancement genioplasty followed by a dermal fat graft and MedporR onlay to the right mandibular body and angle in addition to a refinement genioplasty. Results Follow-up has revealed a partial return of a buccal openbite illustrating the risk of occlusal relapse. Conclusion The case report illustrates the complexity of the orthodontic and surgical management of facial asymmetry, the psychosocial considerations of the patient and the risk of relapse. Multidisciplinary management is essential in the management of Goldenhar Syndrome.

Management of Congenital Melanocytic Naevus (CMN) of the Lower Pole of the Breast Causing Secondary Tuberous Breast Deformity (TBD)- A Case Report and Review of Literature: Congenital Melanocytic Naevus &Tuberous Breast Deformity

A 19-year-old woman was referred with a congenital melanocytic naevus (CMN) involving the lower pole of her right breast, combined with features of tuberous breast deformity (TBD) and breast asymmetry. Staged correction of the breast asymmetry was planned. The first stage involved recruitment of her right upper abdominal skin, in a reverse abdominoplasty manner, to address the lower pole skin deficiency. Extensive radial release of the constriction bands across the original IMF (inframammary fold), and circum-areolar mastopexy were performed. A sub-glandular breast implant was inserted. Four weeks later, she presented with minor inframammary wound breakdown. Washout and removal of the implant, combined with breast parenchymal tissue rearrangement was performed. We performed her planned second stage 3 months later in the form of; a right vertical pattern mastopexy, lipofilling and revision of the reverse abdominoplasty to adjust the nipple and IMF position. The remaining CMN was excised and resurfaced with a full thickness skin graft from the contralateral mastopexy. The leathery quality of CMN makes the achievement of correcting the breast deformity impossible without its excision. This combination of CMN and TBD makes management of these cases more challenging than manging each on its own. To the best of our knowledge, this is the first case report of the effect of moderate CMN on the breast and its development.

Enxerto composto de gordura para correção de distrofia facial em caso de esclerodermia localizada

Localized scleroderma (linear morphea) is a rare disease that causes facial dystrophy and asymmetry in young women. We report the case of a 20-year-old female patient who was treated with novel composite fat grafts. After extracting lipoaspirate from deep subcutaneous fat, the microfat and the unfiltered nanofat were processed separately, and amalgamated, obtaining composite fat grafts. These were meticulously transplanted layer by layer to rebuild the subcutaneous tissue of the patient's face. After one year, a good volume of fat retention was observed with successful correction of asymmetry and restoration of facial balance.

Complex case treatment: Is there a limit for surgery-first approach?

Are there any limits for Surgery-first approach? the article strives to identify the tenets of effective management of complex cases, such as facial asymmetry, with surgery-first approach. The main purpose of the article is in attempting to itemize prerequisites or determining factors, through various degrees of facial asymmetry severity, for the successful management of facial asymmetry cases. The key factors such as (1) assessment of chin deviation, (2) quantification or discernment of transverse occlusal plane canting, (3) spatial orientation evaluation of differential anterior and posterior region transverse occlusal canting, and (4) contemplations of six degrees of freedom (6DoF) (translation movements combined with rotation axis - pitch, roll and yaw) are evaluated. Furthermore, dental alignment, severity of mandibular and maxillary occlusal (anterior and posterior) plane canting, critical cephalometric parameters, such as, incisor mandibular plane angle, and other vital sub- components of facial asymmetry are analysed, in detail. Subsequently, these are coherently synchronized with the maxillomandibular complex (MMC) rotation surgery during planning for the successful execution of facial asymmetry correction. Additionally, the article describes the (1) usage of orthodontic arch wires, (2) selection criteria of specific surgical osteotomies, and (3) coordination of maxillary and mandibular dentition to establish a transitional or treatable malocclusion. In conclusion, a thorough evaluation of the determining factors, as described in the article, for the correction of facial asymmetry with surgery-first, aid in categorising facial asymmetry cases that require minimal pre-surgical orthodontics or without pre-surgical orthodontic treatment, thereby defining the limits of surgery-first.

Fat Grafting in Facial Palsy: A Secondary Revision Technique to Improve the Facial Aesthetics.

Summary:We report our experience of using autologous fat grafting (AFG) as an adjunct to dynamic and static facial reanimation surgical techniques in patients with facial palsy. A consecutive series of patients with facial palsy (congenital or acquired) treated by AFG between September 2007 and October 2017 were reviewed. Multiple strategies for initial dynamic facial reanimation have been utilized. Indications for AFG included asymmetry, volume deficiency, and visible muscle tethering. Standard AFG technique was used with fat harvested from the lower abdomen or thigh and injected into multiple affected areas. Fat grafting was repeated as necessary. Two-dimensional analysis was performed using standardized pre- and postoperative photographs to assess facial symmetry. Patient, surgeon, and independent evaluator satisfaction was recorded using a five-point Likert scale (0–4). Thirty-two patients with a mean age of 43 ± 15.5 years were treated with AFG following facial reanimation. A mean of 1.7 ± 1.4 secondary procedures were performed following initial dynamic reanimation before fat grafting. The average number of AFG episodes was 2.2 ± 1.4 with a mean volume of 12.9 ± 6.0 ml. Minimal complications were seen in either the donor or the recipient sites. There was significant improvement (P ≤ 0.001) of postoperative quantitative facial symmetry following fat grafting. At one-year follow-up, surgeon, patient, and independent evaluator were mostly satisfied (3.06 ± 0.62, 3.31 ± 0.59, and 3.16 ± 0.57, respectively). We report a positive experience of correction of facial asymmetry, contour abnormality and visible muscle pull with fat transplantation following dynamic facial reanimation. The procedure has been shown to be quick and simple, with few complications.

Orthodontic Perspective for Face Asymmetry Correction

Facial symmetry affects the perception of facial beauty. Overall, facial harmony with an appropriate facial proportion and satisfactory midline facial symmetry are crucial factors for facial attractiveness. The role of orthodontists in correcting facial asymmetry begins with providing suitable diagnosis of the condition and identifying patients’ expectations. Through a thorough, subjective clinical evaluation of dentofacial asymmetry, the procedures for the surgical orthodontic management of facial asymmetry are discussed. The aim of this clinical review is to provide information on surgical indications for facial asymmetry, optimal treatment goals, presurgical orthodontic preparation, the surgery-first approach, three-dimensional (3D) surgical simulation, postsurgical orthodontic finishing, and treatment outcome evaluation. A comprehensive 3D diagnosis with appropriate planning, accurate transference of surgical simulation to real surgery, slight overcorrection, periodic assessment of treatment outcomes, and awareness of treatment limitations are essential to improve treatment outcomes of facial asymmetry.

Dentofacial asymmetry: non-surgical orthodontic treatment using extra-alveolar miniscrews

Asymmetric malocclusions have been always a challenge to orthodontists, with different dental, skeletal or dentoskeletal factors being probable causes for the condition. It is key to distinguish between dental and skeletal asymmetry before determining a predictable force system for corrective treatment. The use of mini-implants (MIs) to address anchorage needs in modern orthodontic practice has become an important tool for orthodontists. They have been widely used for anchorage reinforcement purposes and placed in the dentoalveolar region, especially between tooth roots (inter-radicular miniscrews). However, placement sites other than root areas allow more versatility of orthodontic movement since tooth roots do not interfere in tooth displacement, such as the extra-alveolar miniscrews.Objective The objective of the present paper is to present biomechanical concepts in which extra-alveolar mini-implants are placed in the infrazygomatic crest (IZC) and buccal shelf (BS) areas for correction of dento-facial asymmetries allowing predictable outcomes to be achieved with minimal need for patient's compliance and minor mechanic side effects.

New evidence of photobiomodulation and ozone therapy combined in the treatment of Bell's palsy

Bell's palsy is the most common cause of unilateral facial palsy reported in the literature. This condition consists of causing rapid onset and unilateral peripheral paresis/paraesthesia of the seventh cranial nerve. Despite being well documented, its etiology is still uncertain, imposing difficulty in immediate treatment. The combination of laser therapy and ozone therapy was proposed as a new treatment method for Bell's palsy, as it combines the efficacy and response of a therapy with the benefits of a minimally invasive approach. In the present study, we describe the first treatment protocol combining laser therapy and ozone therapy in Brazil, as well as details of the technique for the treatment of Bell's palsy. Case Report: A 59-year-old female with paralysis and paresthesia in the right hemiface, diagnosed for Bell's palsy, underwent a combined treatment of laser therapy and ozone therapy (VK OzonTherapy). After the fourth treatment session, a great clinical response was observed, and another session of the VK OzonTherapy protocol was performed. The patient evolved with significant improvement in the sequelae of right hemifacial paralysis, oro-ocular and eye closure, with rapid recovery of muscle tone and correction of asymmetries. Conclusions: This Report shows that the VK OzonTherapy protocol is an adjunct tool for clinical practice capable of improving the aesthetic-functional quality of life in patients with recent unilateral facial palsy.
