E-Scooter-Related Maxillofacial Fractures: A New Emerging Epidemic During the COVID-19 Period in the Province of Rome, Lazio, Italy: A Monocentric Study Review of 843 Patients Compared With the Pre-COVID-19 Two-Year Period.

INTRODUCTION: Shared vehicles, such as e-scooters and electric bicycles, could potentially accelerate the transition toward sustainable mobility. Focusing on e-scooters, the aim of this study is to show, compared with previous years when e-scooter use was significantly reduced, the increased incidence of maxillofacial bone injuries from e-scooters and the most frequent type of fractures. METHODS: We conducted a monocentric observational retrospective and prospective analysis during the pandemic, from January 1, 2020, until December 31, 2022, on patients' access for maxillofacial traumas at the San Giovanni Addolorata emergency department, trauma hub center, for Lazio district. A total of 383 patients were included. Data on the causes of traumas, type of injury produced, age, gender, nationality, and helmet use were collected. Especially, we analyzed the e-scooter-related facial traumas that had gained a lot of popularity in this period due to the restriction in mobility because of Covid-19, subsequent reduced use of public transport, and the new benefits introduced by the government for e-scooters or bikes. We compared e-scooter facial trauma with all the other kinds of facial fracture etiologies during this period. RESULTS: In our study, the most frequent causes of trauma were assaults (32.6%), accidental falls (24.2%), and sports activities (7.8%). The percentage of trauma among road traffic injuries was almost 24% of the total; in particular, motorcycle/e-scooter traumas was 7.1%, car crashes was 5.5%, pedestrian hits was 4.2%, and bike accidents was 3.1%. Other causes detected were syncope (5.5%), accidental traumas (1.8%), and epileptic crisis (1.1%). Focusing on road traffic injury access in our emergency department, compared with those between 2017 and 2019, it emerged that e-scooter-related facial traumas in the past two years have had a remarkable rise. In fact, there was a total of 27 patients (52% male and 48% female) instead of 5 between 2017 and 2019. The average age was 29 years. The most frequent types of e-scooter-related fractures were those to the nasal bones (29.7%), followed by mandibular fractures (unifocal 7.4%, bifocal 18.5%, trifocal 7.4%, and condylar 7.4%), zygomatic-maxillo fractures (18.4%), complex fractures (7.4%), and maxilla (3.7%). Among 27 observed electric scooter riders, nobody wore a helmet. CONCLUSIONS: Injuries associated with the use of e-scooters are a new phenomenon and mainly affect the craniofacial region due to the dynamic nature of the trauma. Although these vehicles have become increasingly common over the years and accepted within regulatory frameworks, the traffic rules are not ready to integrate e-scooters into the transport systems due to the lack of adequate legislation, and the lack of implementation in the form of facial safety devices or safety skills training for e-scooter riders.

Management of Orbital Medial Wall Fracture With Endonasal Balloon.

Medial wall fracture of the orbit is a condition that requires surgical correction should the patient presents a series of signs and symptoms such as diplopia and enophthalmos. The classical external approaches for exposure like the transconjunctival or transcutaneous approach have been replaced in specific cases by endoscopic approaches as they are less invasive and they eliminate any risk of potential scarring. Larger defects where the medial wall is comminuted or bony fragments are missing could be reconstructed with permanent autogenous or alloplastic materials. When bony fragments are present, a reduction of the fracture can be performed instead, with only a temporary alloplastic material for support. In this study, the authors discuss our experience regarding the management of orbital medial wall fractures by endoscopic endonasal balloon in 14 patients and describe its indications and contraindications. The authors concluded that the balloon achieves satisfactory mechanical support for the fracture to heal and it can be easily removed on an outpatient basis.

Endoscopic endonasal approaches for cerebrospinal fluid leaks repair.

OBJECTIVE: A variety of techniques have been described for the repair of cerebrospinal fluid (CSF) leaks at the anterior skull base. Conservative management includes bed rest, avoidance of straining activities, and temporary CSF diversion with serial lumbar punctures or lumbar drains. Surgical repair may be achieved transcranially through a bifrontal craniotomy, extracranially through an external ethmoidectomy or frontal sinusotomy, or transnasally with microscopic or endoscopic visualization. METHOD: Between January 2006 and May 2011, 30 patients with nontraumatic and traumatic CSF rhinorrhea were treated at the Departments of Neurosurgery and Maxillofacial Surgery of the Universities of Rome 'La Sapienza'. All patients underwent surgery: 5 patients (15%) were treated by a combined intracranial and endoscopic endonasal approach and 25 patients were treated (91.1%) by the endoscopic endonasal approach alone. In our study, we used autologous material, the fascia lata, free grafts of septal or middle turbinate mucoperichondrium, and septal cartilage grafts, and in cases with a large deficit in the posterior wall of the sphenoid or clivus, a pedicle flap from sphenopalatine artery of septal mucosa is used. RESULTS: Only in 2 cases was there an appearance of secondary rhinoliquorrhea with a success rate of 94%, in line with what is described in international literature. CONCLUSIONS: Posttraumatic cerebrospinal leak in our experience can be treated through endoscopic approach, in selected cases, using autologous materials with a few relapse of the pathology. Endoscopic endonasal technique offers a high viewing of surgical field and it permits to manage even larger lesions with minimally invasivity.

Application of piezoelectric device in endoscopic sinus surgery.

New applications of piezoelectric device have been already documented from otologic and ophthalmic endoscopic studies. The authors describe a first experience in endoscopic sinus surgery with piezosurgery to approach the paranasal sinus. Patients involved in this study presented for rhinogenous headache, rhinorrhea, nasal obstruction, and sinusitis. Radiological studies such as computed tomography of paranasal sinus and a correct clinical examination with a rigid endoscope 0 degrees were carried out, to exclude from the procedure patients with polyposis or other soft-tissue diseases. In fact, because of piezosurgery properties of micrometric and selected cutting on mineralized tissues, it has been used only to treat bone or cartilage anomalies of nasal sinus. The main advantages of the technique include soft-tissue protection and optimal visibility in the surgical field with decreased blood loss. From this preliminary report, the stability of mucous membrane previously cut has been documented by endoscopic follow-up, and the resolution of the main symptom of headache was referred. The main indications for piezosurgery shown in literature are in oral surgery, such as sinus lift, bone graft harvesting, osteogenic distraction, ridge expansion, endodontic surgery, and periodontal surgery. Other applications have been shown in otology, neurosurgery, ophthalmology, and orthopedics. Authors describe as a promising technique the piezoelectric device use in functional endoscopic paranasal sinus surgery in selected cases, with a minimal mucosal approach and thus the preservation of ventilation.

Intramasseterin-infiltrating angiolipoma: a challenging diagnosis.

Angiolipomas are benign mesenchymal tumors infrequently affecting the head and neck region, manifesting themselves as small (<4 cm), slow-growing mass that are painful or tender to palpation. Ultrasonography, fine needle aspiration biopsy, computed tomography, and magnetic resonance imaging can be used to make a diagnosis. Surgical excision is the treatment of choice in both infiltrating and noninfiltrating forms, even if liposuction can be considered in multiple forms. We describe a case of infiltrating intramasseterin angiolipoma, in which diagnosis was suspected after magnetic resonance imaging with gadolinium; then a transoral surgical excision was performed. To the best of our knowledge, only 1 other case of intramasseterin-infiltrating angiolipoma has been previously described.

Biomaterial implantation in facial esthetic diseases: ultrasonography monitor follow-up.

Facial deficit diseases are corrected by biomaterial implantation. The ideal biomaterial should be easy to implant and remove and simple to be identified by a low-dose radiation and low-cost radiologic technique. The purpose of this work was to evaluate ultrasonography (US) as a technique in monitoring biomaterial status after operation. In the last 3 years, for this study we used polyethylene porosus and polyacrylamide. Our study included 300 patients grouped accordingly as follows: malformative syndromes, degenerative syndromes, and esthetic problems, results of skull-facial traumas, and whether they are treated in the early phase and or the late phase. In this paper, we describe the better 15 clinical cases for their excellent result and for their variety of US images. Ultrasonography has been shown as an excellent way to visualize clinical features and a possible pathologic process of an implanted biomaterial; it is a noninvasive, low-radiation and low-cost dose radiologic technique. Reconstruction in facial deficit diseases needs adequate biomaterial to implant and a careful patients observation, that is, both clinical and radiologic. Ultrasonography is a fundamental component of the follow up of implanted biomaterial patients.

Maxillofacial prosthetic rehabilitation using extraoral implants.

The prosthetic rehabilitation is a surgical alternative in functional-aesthetic facial reconstruction when the conventional reconstructive surgery cannot be applied either because of the psychophysical conditions of the patient or because of an excessive substance loss. From May 2002, 35 facial prosthesis (111 implants) have been positioned. Defects were congenital (N = 12), consequent to trauma (N = 8) and to demolitive surgery for malignant tumors (N= 8), and infection (N = 7). In 4 patients, implants were placed in previously irradiated areas. A total of 111 titanium implants were placed to support 21 auricular prostheses (bilateral in 2 cases), 4 orbital prostheses, 8 nasal prostheses, and 2 complex midfacial prostheses. Implant failure was observed for 2 of the 3 implants placed to support a nasal epithesis in a patient with hepatitis C virus, with an important parodontal disease, who experienced a postinfective necrosis of the nose after a liver transplantation; it was necessary to place an adhesive prosthesis. An implant failure was also observed in a diabetic patient with an extensive midfacial defects due to a mycotic infection, but it did not compromise the retention of the prosthesis. According to our experience, the indication to epithesis is when the conventional reconstructive interventions is inapplicable.

Unusual foreign body in the nasal cavity.

Foreign objects frequently have been reported in the nasal structures, often these foreign bodies are occasionally inhaled by children or they are often inserted in nasal cavities after various accidents. Frequently, the presence of foreign bodies in the nose represents an emergency, particularly for pediatric patients where the incidence is high. The report in this article described an unusual nasal foreign body in an adult discovered incidentally during a cranial radiography. This report is an unusual case of facial asymmetry caused by a foreign nasal body in adult, which is destitute of complications, connected to long-term presence of the intranasal button. The finding was accidental; moreover the patient was an adult and did not present a clear symptomatology. Through careful clinical and fibroscopy exam, valuating also the site of the foreign body, it is necessary an intranasal surgery treatment. The results of the treatment is connected to a combined use of different branches of learning with the aim of obtaining positive results from both a clinical and legal point of view.

Nevus sebaceus of Jadassohn.

The nevus sebaceus of Jadassohn (SNJ) is a hamartomatous disorder of the skin and its adnexa pertaining to the group of "organoid nevi,'' most frequently involving the face and scalp. During adulthood, patients with SNJ have a 10% to 20% risk of the development of cutaneous or adnexal neoplasia, so that prophylactic excision before puberty is recommended by most authors, and tissue expansion is considered to be the best method of reconstruction. It has been largely demonstrated in literature that most of the lesions that have been interpreted as basal cell carcinoma (BCC) are actually examples of primitive follicular induction or trichoblastomas, not authentic BCCs. A literature review on histopathologic findings associated with SNJ and a retrospective chart review of two cases occurring in young females are presented. In one case, the lesion was treated by intraoperative expander-assisted reduction and scalp graft (Case 1); in the other one, a primary closure with adjacent tissue was performed (Case 2). No signs of malignant degeneration or residual pathology have been found. For treatment of the biggest lesions, when preoperative tissue expansion cannot be performed, intraoperative one, transfer of a scalp graft has been shown to be a good reconstructive method. For the smallest lesions, a primary closure with adjacent tissue is sufficient.

Brain abscess by mycotic and bacterial infection in a diabetic patient: clinical report and review of literature.

This report presents a case of lethal invasive mucormycosis, a rare fungal infection, which predominantly affects immunocompromised patients, and is reported in a 57-year-old female who presented with cerebral abscess. The patient, who had undiagnosed diabetes mellitus, presented with extensive right hemifacial deficiency of the bones and soft tissues consequent to surgical resection of the ethmoid-spheno-maxillo-orbital district after mucormycosis. A reconstruction with a pectoral pedunculated flap was performed. The maxillary swelling extended to the contiguous area, involving the palate and homolateral orbital floor. Mucous and cutaneous samples showed the presence of Aspergillus fumigatus, and diagnosis of rhinocerebral mucormycosis was made. The patients also presented with a right hemiplegia consequent to a cerebral abscess by Eikenella corrodens. The authors decided to position an intraoral prosthesis to restore palatal integrity and masticatory function and inserted four titanium fixtures for the retention of the bone-anchored facial prosthesis.

Parry-Romberg syndrome.

The authors report an unusual case of Parry-Romberg syndrome (PRS). Magnetic resonance imaging and computed tomography scan of the craniofacial region and surgical correction of enophthalmos were performed. Results after the operative intervention included persistent palpebral edema and ecchymosis and transient choroid vasculitis of the right eye, highlighted with echography and fluorescein angiography. The fundus oculi examination showed retinal choroid folds. Immunological test results were weakly positive. The authors conclude enophthalmos, associated with right side hemi atrophy, and the transient choroids vasculitis support the diagnosis of PRS. Furthermore, it is suggested the case had an autoimmune etiology, rather than a hemi facial asymmetry caused by a facial trauma that occurred in puberty.
