Influence of SARS-CoV-2 lockdown on the incidence of facial trauma in a tertiary care hospital in Rome, Italy.

BACKGROUND: Italy has been the first affected country in the western hemisphere by SARS-CoV-2 with over 200,000 cases during the first months of the pandemics. To control the spread of the virus, the whole country was placed under lockdown with limitations in the circulation of people and vehicles from March 2020 to the first half of the month of May. METHODS: We aimed to analyze the incidence and type of facial traumas referred to our tertiary care hospital during the months of Italy lockdown due to SARS-CoV-2 spread compared with those during the same months of 2019 to determine eventual variations in the incidence, type and causes of trauma. RESULTS: During the 2 months of COVID-19-related lockdown, a dramatic decrease in facial trauma patients was observed at our tertiary care hospital with a shift toward older age ranges. Regarding the causes of trauma, the largest percentage reduction was found in road, sports and work accidents; this percentage reduction was not found in aggressions. CONCLUSIONS: A small increase in the percentage was also found regarding surgical indications, likely because more severe cases were more prone to be referred to the hospital despite the fear of being infected.

An Orthodontic Index assessment and its relationship with total treatment time in surgery first orthognathic approach: an observational study.

BACKGROUND: The aim of this study was to highlight the connection between orthodontic difficulty before surgical treatment and in the transient malocclusion as evaluated by the mean of the of Complexity, Outcome, and Need (ICON) Score and total treatment time in surgery-first approach (SFA). METHODS: For each patient, the ICON Score was evaluated preoperatively and on the 3rd postoperative day in order to assess the orthodontic difficulty of presurgical occlusion and the transient malocclusion. RESULTS: Our group of patients at the preoperative stage showed score values between hard and very hard with only one patient scored as "easy" and nine "medium" patients. All scores lowered after surgical treatment. This confirms that the surgery first approach can change a malocclusion from not orthodontically treatable to an orthodontically treatable one. In our study, this was objectified by improvements in the ICON Score. CONCLUSIONS: In the conventional three-phase approach of orthognathic surgery the total treatment time found in literature is around 18-36 months. In our study, even the most difficult cases do not have a duration of more than 15 months This demonstrates that the surgery-first approach can reduce the total treatment time even in more severe cases.

Patient First: Surgery First and More.

INTRODUCTION: The success of surgery first approach has been defined by the number of advantages offered and is definitively determined by the satisfaction of the patients themselves. The strength of this protocol resides in its philosophy that puts the patient at the center of the whole diagnostic-therapeutic process. The compliance of the patient, its happiness and comfort are the best guarantee of a good final results. While pursuing this philosophy we have wondered whether there was way to increase the comfort of surgery first approach even more and to make it even more appealing for the patients. For these reasons, we have decided to work on a preliminary protocol in order to reduce or even eliminate the use of orthodontic braces and wires during perioperative stages. Materials and Methods: No orthodontic braces or wires are bonded on the teeth before surgery. Intraoperatory intermaxillary fixation (IMF) is carried out with the use of IMF screws which are positioned at the beginning of the operation on the edge between keratinized and nonkeratinized gingiva. Once the osteotomies are performed IMF with IMF screws is carried out on the planned occlusion with the use of surgical splints.Discussion and Conclusions: In selected cases the postsurgical orthodontic treatment can be carried out with the use of clear aligners, completely eliminating the need of braces and wires with an additional level of comfort.

Approach to Fronto-Orbital Sequelae in Anterior Synostotic Plagiocephaly: Our Flow Chart Based on Di Rocco Classification.

INTRODUCTION: Anterior synostotic plagiocephaly recognizes the synostosis of one of the hemicoronal sutures as a cause and can manifest itself with varying degrees of severity. Clinically it presents a reduction of the sagittal growth of the affected side and flattening of the frontoparietal complex. MATERIALS AND METHODS: The authors retrospectively examined our case sample dividing it into 3 groups based on the Di Rocco classification. For each category, we assessed the extent of facial alterations at the end of skeletal growth and retrospectively analyzed the surgical options aimed at correcting aesthetic and skeletal deficits. RESULTS: The authors found that predictable results could be obtained by standardizing the surgical procedure based on Di Rocco's classification groups; in particular, the authors achieved satisfactory results by assigning a specific surgical procedure to each class.

Virtual Surgical Planning for Reconstruction of Giant Ameloblastoma of the Mandible.

Ameloblastoma is a histologically benign tumor that behaves aggressively because of its tendency to invade local structures, and it has a high probability of local recurrence. If neglected, ameloblastomas can grow substantially over the course of years, reaching the size of giant ameloblastomas. This large size can lead to deformities in facial appearance and impairments in speaking, swallowing, eating, and breathing.Surgical planning can be challenging because of the extension of the tumor and the consequent reconstructive issues.In this article, we present our experience with the reconstruction of 2 cases of giant ameloblastomas planned on the basis of occlusal casts and acrylic splints. In these patients, computerized planning was rendered complex and potentially inaccurate because of the dimensions of the tumor, the loss of anatomical landmarks, and the loss of occlusal landmarks. The cases were successfully reconstructed, but the technique can be flawed. A 3-dimensional virtual model of the mandible can be used as a template to develop cutting guides for reconstruction with free fibular flaps. This will allow us to overcome limitations, standardize the procedure, and achieve optimal functional and aesthetic results.

Use of an Oral Device in the Stabilization of Facial Advancement after Early Removal of the Osteodistraction Device for Postoperative Sequelae.

The aim of this study is to present an oral device that improves splanchnocranium stability after osteodistraction in children treated for correction of craniofacial malformations. When removal of the distraction device before the end of the treatment is necessary, the reposition of a new fixation system might not be possible. In these cases, regrown bone is immature, and relapse of malformation occurs frequently. We have been treating these cases by the application of an oral device named Maxillary Advancement Contention (MAC). MAC is used in every patient when any complication interrupts the protocol of osteodistraction before the end of the stabilization time. The device is placed immediately after the removal of the distraction device and left in place for at least three months. We used MAC in six children surgically treated for correction of craniosynostosis with facial or craniofacial advancement. To establish the relapse of malformation we analyzed relations Sella-Nasion-Orbitale (SNOr) and Sella-Nasion-A point (SNA) angles before application of the MAC and after one year. The analysis of stability was excellent in every patient. This device might help, with a minimally invasive procedure, to maintain the obtained advancement allowing stabilization of the regrown bone.

Use of Navigation System in Craniofacial Surgery.

The use of navigated surgery in the treatment of craniofacial malformations can help obtain optimal results. In this article, the authors will discuss a case of anterior plagiocephaly, corrected with frontorbital bandeau remodeling. Navigation was used during the osteotomy and the reposition phase to ensure the correct positioning of the osteotomy instruments. It was also used to ensure that the bandeau was correctly repositioned in accordance with the surgical plan determined during the virtual simulation phase of the surgery.

Piezosurgery in Pediatric Neurosurgery.

BACKGROUND: Piezosurgery (PS) has gained increasing dispersion in neurosurgery. In pediatric neurosurgery, the experience is limited to craniosynostosis surgery. The present study assesses PS in the pediatric population, also considering outcomes and complications in cranial and spinal procedures. METHODS: All consecutive craniotomies and laminotomies, performed with PS (group A) or conventional osteotomes (group B) in the 2014-2017 period were reviewed. The following variables were analyzed: dural tears, estimated blood loss and need of transfusion, cosmetic outcome (Sloan score), and operative times. A review of the pertinent literature is included. RESULTS: 172 children were enrolled, 90 in group A and 82 in group B. The mean follow-up time was 2.1 years. A statistically significant difference in favor of group A was found about EBL (105 vs. 113 ml) and late outcome (Sloan class A 98.5% vs. 91.5%). PS also reduced the risk of dural tears (1 vs. 7 cases in groups A and B, respectively) and blood transfusion (52% vs. 55.5%) but without statistical significance. The operative times were significantly shorter in group B (13 vs. 23 minutes), although the newer PS plus (PSP) was demonstrated to significantly shorten these times compared with the traditional PS (3.5 vs. 6.5 minutes for orbitotomy and 7.5 vs. 9.5 minutes for hemicraniotomy). CONCLUSIONS: PS is a safe and effective tool that can be specifically recommended for bone splitting and graft, laminotomy, and craniotomy in cosmetically eloquent areas. The limit of operation times can be overcome by a learning curve in neurosurgery and PSP.

The Rules of Attractiveness: A Study on the Lower Facial Third.

What is considered attractive may not fall into the "norm," and it can vary from culture to culture and depending on the historical time, for this reason the standard cephalometric and antropometric references may not be sufficient in these cases.Lately some techniques have arose to popularity that are aimed to changing the frontal and lateral aspect of the facial lower third, such as V-line or the Chin-Wing Osteotomy technique, but no reference system exists at the moment to define to which extent a modification of the lower third falls within what is considered beautiful, and everything is left to the patient's will or to the surgeon's sensitivity.The aim of this article is to study which antropometric value is considered attractive by the most for what concerns the frontal shape of the lower third of the face.Twenty-four female models were enrolled in this study and the angle taken into consideration was the one at the intersection between the 2 lines connecting the cutaneous gonial angle of each side of the face and the most external part of the chin on the same side. Measures were made on pictures in frontal view.Two hundred two random examiners were asked to see the pictures and rate them as attractive or nonattractive.Results were then paired with the angles values.Among the models the higher angle measured was 107.5° (found in 1 individual) while the lower angle was 76° (found in 1 individual), the average measure calculated was 88.3° while the median angle was 89.5°.According to the result the subjects considered more attractive were those with an angle between 84.5 and 91.5 (92 for male examiners).This could be an important starting point for studies who can evaluate attractiveness from a numerical point of view.

Alveolar ridge augmentation with maxillary sinus elevation and split crest: Comparison of 2 surgical procedures.

The purpose of this study was to evaluate the clinical and radiological outcomes of 2 piezosurgical split techniques performed in conjunction with the sinus lift.The present retrospective study included 20 patients with edentulism of the posterior maxilla who had undergone the sinus lift and alveolar ridge split treatment separately or the sinus lift combined with the monoblock alveolar ridge split. Differences between these 2 techniques were analyzed.All the surrounding areas successfully produced an adequate bone volume for the insertion of implants. A clinical evaluation showed a mean vertical augmentation of 3.6 ±â€Š0.4 mm in Group A and 3.2 ±â€Š0.7 mm in Group B. With regards to the lateral augmentation, the clinical evaluation gives a mean gain of 5.2 ±â€Š0.3 mm in Group A and 4.9 ±â€Š0.5 mm in Group B. The mean vertical and horizontal bone augmentation recorded for both types of surgical procedures were comparable.The proposed surgical procedures enabled the tridimensional volume of the alveolar ridge to be recreated. This resulted in the creation of a natural contour of hard and soft tissues which enabled a functional and aesthetic rehabilitation of the edentulous posterior maxilla to be obtained.

Phosphaturic mesenchymal tumor, an unusual localization in head and neck.

Phosphaturic mesenchymal tumor (PMT) is a rare mesenchymal neoplasm associated with tumor-induced osteomalacia involving bone and soft tissue that produces paraneoplastic hypophosphatemic osteomalacia. The common physiologic defect in this conditions involves an impairment in renal tubular phosphate reabsorption with a downregulation of renal 1α-hydroxylase activity, while calcium metabolism remains essentially unaffected. Microscopic features consist of spindle cells, multinucleated giant cells and calcifications embedded in a chondromyxoid matrix with variable cellularity and prominent vascularity. Approximately 95% of PMTs involve the extremities and appendicular skeleton, with only 5% occurring in the head and neck region. Localization in the head and neck is pretty uncommon, nose and paranasal sinuses are preferentially affected. Due to its rarity, the purpose of the study was to report a new case of PMT whose locations in temporomandibular joint was never reported in literature.

Pseudoaneurysm of the internal maxillary artery secondary to subcondylar fracture: case report and literature review.

Pseudoaneurysms are an uncommon complication of mandibular condylar-subcondylar fractures; however, if present, their recognition and management is mandatory to avoid life-threatening situations. The authors report a case of internal maxillary artery pseudoaneurysm rupture that occurred after an open reduction and internal fixation of a mandibular subcondylar fracture, along with a review of the literature.

Orbital Desmoid-Type Fibromatosis: A Case Report and Literature Review.

PURPOSE: Desmoid-type fibromatosis is a benign fibrous neoplasia originating from connective tissue, fascial planes, and musculoaponeurotic structures of the muscles. Currently, there is no evidence-based treatment approach available for desmoid fibromatosis. In this article, a case of a patient in the pediatric age affected by desmoid fibromatosis localized in the orbit is presented. The aim of the article is to describe this unusual and rare location for the desmoid fibromatosis and outline the principle phases in the decision-making process and the therapeutic alternatives for a patient affected by desmoid fibromatosis. METHODS: The protocol of this review included study objectives, search strategy, and selection criteria. The primary end point of this study was to analyze the head and neck desmoid fibromatosis. The secondary end point was to identify the available therapies and assess their specific indications. RESULTS: The mean age of patients was 18.9 years ranging from 0 to 66, and 52% were female. A bimodal age distribution was observed, and two age peaks were identified: 0-14 years (57%) and 28-42 years (18%). The most common involved areas were the mandible (25%) followed by the neck (21%). In 86% of the cases, the treatment was the surgical resection of the disease, and only in 5% of the cases, the surgical resection was followed by adjuvant radiotherapy. CONCLUSION: The orbital location is extremely rare, especially in the pediatric population. The management of desmoid fibromatosis is based on the function preservation and the maintenance of a good quality of life, but in case of symptomatic patients or aggressive course of the disease or risk of functional damages, the surgical approach may be considered. Therapeutic alternatives to surgical resection are radiotherapy and systemic therapy.

The Arterialized Facial Artery Musculo-Mucosal Island Flap for Post-Oncological Tongue Reconstruction.

BACKGROUND: In 1992, Pribaz described the facial artery musculomucosal flap (FAMM), an axial musculomucosal flap based on the facial artery. The FAMM flap, a modification of the nasolabial and buccal mucosal flaps, is widely used in the reconstruction of defects in the oral cavity. Many modifications of this flap have been described in the literature. Here we aimed to explore the use of an arterialized tunnelized FAMM island flap (a-FAMMIF) for the reconstruction tongue defects after tumor resection. METHOD: From January 2015 to December 2016, five cases of tongue cancer were selected for the use of arterialized FAMMIF flap to reconstruct defects after tumor resection. RESULTS: Reconstruction was successful in all cases, except one case of total flap necrosis; partial necrosis of the flap occurred in two patients, which were solved with medications. CONCLUSION: The authors consider the a-FAMMIF an unreliable flap in the reconstruction of tongue defects.The authors recommend avoiding tunneling and island modification when the vein is not included in the pedicle.

Effect of Surgery First Orthognathic Approach on the Temporomandibular Joint.

INTRODUCTION: Correction of severe malocclusions with skeletal discrepancies requires orthodontic treatment in combination with orthognathic surgery. Even though conventional orthognathic surgery (COS) is a common and well-accepted approach its influence on the signs and symptoms of temporomandibular disorders (TMDs) is still debated. Recently with the introduction of surgery first approach, a different timing for the management of dentoskeletal imbalances has been proposed. The present study is aimed at assessing the relationship between surgery first approach and temporomandibular joint (TMJ) disorders. METHODS: The study sample consisted of 24 patients who were selected to be treated with surgery first approach. Clinical follow-ups after surgery were performed every week for the first month, at 3 months, 6 months, and at 1 year. A radiological follow-up was performed at 1 week and at 1 year after the operation with a panorex and a latero-lateral teleradiograph. To assess the effect of surgery first approach on the TMDs signs and symptoms, a clinical assessment was performed 4 days before surgery (T1), 6 months after surgery (T2), and 1 year postoperatively (T3). RESULTS: The results of the authors' study show that pain assessment revealed a general improvement of this symptom in correspondence to TMJ and masticatory muscles except in the masseter and neck region. Also joint noises, TMJ functioning, migraine, and headache underwent a considerable improvement. CONCLUSION: Surgery first approach is an innovative orthognathic procedure and, by undergoing surgery first approach, patients with pre-existing TMJ dysfunction may experience a significant improvement or even resolution of the TMDs signs and symptoms.

Surgery-first orthognathic approach vs traditional orthognathic approach: Oral health-related quality of life assessed with 2 questionnaires.

INTRODUCTION: The purposes of the study were to investigate and evaluate the differences detected by the patients between the traditional orthognathic approach and the surgery-first one in terms of level of satisfaction and quality of life. METHODS: A total of 30 patients who underwent orthognathic surgery for correction of malocclusions were selected and included in this study. Fifteen patients were treated with the conventional orthognathic surgery approach, and 15 patients with the surgery-first approach. Variables were assessed through the Orthognathic Quality of Life Questionnaire and the Oral Health Impact Profile questionnaire and analyzed with 2-way repeated-measures analysis of variance. RESULTS: The results showed significant differences in terms of the Orthognathic Quality of Life Questionnaire (P <0.001) and the Oral Health Impact Profile (P <0.001) scores within groups between the first and last administrations of both questionnaires. Differences in the control group between first and second administrations were also significant. Questionnaire scores showed an immediate increase of quality of life after surgery in the surgery-first group and an initial worsening during orthodontic treatment in the traditional approach group followed by postoperative improvement. CONCLUSIONS: This study showed that the worsening of the facial profile during the traditional orthognathic surgery approach decompensation phase has a negative impact on the perception of patients' quality of life. Surgeons should consider the possibility of a surgery-first approach to prevent this occurrence.

Surgical Orthodontic Treatment of a Patient Affected by Type 1 Myotonic Dystrophy (Steinert Syndrome).

Myotonic dystrophy, or Steinert's disease, is the most common form of muscular dystrophy that occurs in adults. This multisystemic form involves the skeletal muscles but affects also the eye, the endocrine system, the central nervous system, and the cardiac system. The weakness of the facial muscles causes a characteristic facial appearance frequently associated with malocclusions. Young people with myotonic dystrophy, who also have severe malocclusions, have bad oral functions such as chewing, breathing, and phonation. We present a case report of a 15-year-old boy with anterior open bite, upper and lower dental crowding, bilateral crossbite, and constriction of the upper jaw with a high and narrow palate. The patient's need was to improve his quality of life. Because of the severity of skeletal malocclusion, it was necessary to schedule a combined orthodontic and surgical therapy in order to achieve the highest aesthetic and functional result. Although therapy caused an improvement in patient's quality of life, the clinical management of the case was hard. The article shows a balance between costs and benefits of a therapy that challenges the nature of the main problem of the patient, and it is useful to identify the most appropriate course of treatment for similar cases.
