Effects of the COVID-19 Pandemic on Everyday Neurosurgical Practice in Alsace, France: Lessons Learned, Current Perspectives, and Future Challenges-Preliminary Results of a Longitudinal Multicentric Study Registry.

Background and Objectives: The global outbreak caused by the SARS-CoV-2 pandemic disrupted healthcare worldwide, impacting the organization of intensive care units and surgical care units. This study aimed to document the daily neurosurgical activity in Alsace, France, one of the European epicenters of the pandemic, and provide evidence of the adaptive strategies deployed during such a critical time for healthcare services. Materials and Methods: The multicentric longitudinal study was based on a prospective cohort of patients requiring neurosurgical care in the Neurosurgical Departments of Alsace, France, between March 2020 and March 2022. Surgical activity was compared with pre-pandemic performances through data obtained from electronic patient records. Results: A total of 3842 patients benefited from care in a neurosurgical unit during the period of interest; 2352 of them underwent surgeries with a wide range of pathologies treated. Surgeries were initially limited to neurosurgical emergencies only, then urgent cases were slowly reinstated; however, a significant drop in surgical volume and case mix was noticed during lockdown (March-May 2020). The crisis continued to impact surgical activity until March 2022; functional procedures were postponed, though some spine surgeries could progressively be performed starting in October 2021. Various social factors, such as increased alcohol consumption during the pandemic, influenced the severity of traumatic pathologies. The progressive return to the usual profile of surgical activity was characterized by a rebound of oncological interventions. Deferrable procedures for elective spinal and functional pathologies were the most affected, with unexpected medical and social impacts. Conclusions: The task shifting and task sharing approaches implemented during the first wave of the pandemic supported the reorganization of neurosurgical care in its aftermath and enabled the safe and timely execution of a broad spectrum of surgeries. Despite the substantial disruption to routine practices, marked by a significant reduction in elective surgical volumes, comprehensive records demonstrate the successful management of the full range of neurosurgical pathologies. This underscores the efficacy of adaptive strategies in navigating the challenges imposed by the largest healthcare crisis in recent history. Those lessons will continue to provide valuable insights and guidance for health and care managers to prepare for future unpredictable scenarios.

Covid-19 pandemic: the impact of Italian lockdown on maxillofacial trauma incidence in southern Tuscany.

The outbreak of the Covid-19 pandemic has seriously affected our society. Governments have difficult situations by adopting strict and severe mitigation measures in order to contain the pandemic spreading. These decisions influenced significatively people's behavior changing their habits and routines. This study offers a statistical analysis of the incidence of the Maxillo-Facial traumas in Tuscany southern area, during the pandemic lockdown. The statistical analyzed has been obtained comparing the maxillo-facial trauma occurrence during the Italian lockdown between the 9th of March and the 18th of May 2020 in comparison with same period of the five previous years. KEY WORDS: Covid-19, Italian covid-19, Maxillofacial surgery, Maxillofacial trauma, Pandemic, Surgery management, Trauma incidence in Italy.

Meningioma en plaque A case report.

Meningiomas as anatomo-pathological entities were first described in the sixteenth century, but it was Harvey Cusching who in 1922 proposed to identify them with the term "meningioma". They are the most common intracranial tumors, occur between middle and late age and prefer female sex. The symptoms depend on their position with respect to the brain regions. These are mostly benign neoplasms, but there are atypical and even malignant forms. Plaque meningioma refers to a specific macroscopic aspect of the meningioma, due to diffuse dural involvement and usually with extracranial extension. We report here a case of plaque convex meningioma with typical grade I. Key Words: En plaque, Meningioma, WHO Meningioma.

Orthognathic surgery: a randomized study comparing Piezosurgery and Saw techniques.

INTRODUCTION: The purpose of this study was to evaluate specific parameters: intra-operative time, facial swelling, degree of pain (VAS scale), recovery time and neurosensory disturbance in patients who underwent orthognathic surgery either using piezo or saw devices. MATERIAL AND METHODS: We designed a retrospective study, which included 100 patients who underwent bilateral sagittal split osteotomy (BSSO) surgery combined with maxillary Le Fort I. They were separated into 2 groups of 50 patients each. The surgeries were performed between September 2015 and April 2017 by the same surgeon. RESULTS: Intra-op time is unchanged but patients operated with the Piezo devices requested fewer painkilling medication and were dismissed on the second day after the surgery. Neurosensory recovery was statistically significant in the Piezo group. CONCLUSION: Far less post-op swelling and the reduction in the use of painkillers lead to a speedier recovery in patients who underwent orthognathic surgery using Piezosurgery. These patients also recovered more sensitivity in the lower lip area. KEY WORDS: Orthognatic surgery, Piezosurgery, Saw.

Intracranial soft-tissue glomus tumor (glomangioma) in a young-woman. A case report and review of the literature.

BACKGROUND: Glomus tumors, or glomangiomas, are benign vascular tumors typically seen at distal extremities. These tumors differ from paragangliomas and classically present in the female population between the 4th and 5th decade. Intracranial localizations have not been described in literature in the adult population. CASE DESCRIPTION: We present a case of a 32 year-old woman with a 3 months history of progressive left-sided visual loss and headache. A pre-operative MRI showed a homogeneously enhancing lesion extending from the left cavernous sinus to middle cranial fossa at first suspected to be a cavernous sinus meningioma. Eventually, histopathological analysis concluded for a glomangioma diagnosis. Post-operative RT was also performed. CONCLUSIONS: From our experience it is very important for clinical management considering glomangiomas in differential diagnosis of a homogeneously enhancing extra axial mass. Subtotal resection followed by radiation therapy determined no recurrence of the disease up to 7 years. KEY WORDS: Glomangioma, Glomus tumor, Soft-tissue tumor.

Rare case of giant lymphocele treated with supramicrosurgical approach.

INTRODUCTION: Lymphocele (or cystic lymphangioma) is a typical disease of the lymphatic vascukarization caused by lymphatic fluid leakage. Lymphatic leakage can result from traumas or as a complication of surgical procedures. Clinic is vague and surgical resection is still considered the most effective approach. Thereby, a standpoint should be the identification and treatment of afferent lymphatic channels which can be addressed by LVA. CASE PRESENTATION: The authors describe a rare case of a giant lymphocele occurred in a 56-year-old Caucasian woman treated for endometrial carcinoma. Lymphocele was refractory to percutaneous drainage and compressive treatment. Therefore surgical excision in combination with supramicrosurgical lymphatico-venular anastomosis (LVA) was scheduled. CONCLUSIONS: The aim of the report is to offer an overview on the main therapeutic options to treat lymphocele and to demonstrate the effectiveness of combining excision with lymphatic microsurgery. KEY WORDS: Inguinal lymphocele, LVA, Supramicrosurgery.

Complex craniomaxillofacial gunshot wounds A step-by-step multidisciplinary approach.

BACKGROUND: Gunshot injuries of the viscerocranium are rarely reported. Penetrating wounds to the cranio-maxillofacial region pose a significant challenge for surgeons as they often comprise serious soft tissue, bone and cerebral defects. We present a case report of a 42-year old female with a gunshot wound to the viscerocranium after suicidal attempt. Series of image of the disease course are available. CASE DESCRIPTION: A 42-year-old female presented with gunshot wound to the viscerocranium after a suicidal attempt. At the arrival GCS was 8/15 and general examination showed the inlet wound in the submental region whereas the outlet one in the left temporal skull area. After first rescue procedures, ICP was monitored before proceeding surgically. Due to massive hemorrhage, embolization of ianternal maxillary artery was performed. Afterwards, tracheostomy, surgical reduction of multiple maxillo-facial fractures and ocular avulsion were performed. In a second time, ICP monitoring and CT scan revealed ICH signs due to intraparenchimal injures. The patient underwent to a second surgical procedure, consisting of bifrontal decompressive craniectomy. The patient was discharged on 20th post-op day to a rehabilitation center. She returned to our department after 4 months to perform a craniomaxillofacial recostruction. She presented 15 in GCS, left ptosis, left VII cranial nerve deficit, decannulated, KPS 100%. CONCLUSION: A step-to-step multidisciplinary approach both with Neurosurgeons and Maxillo-facial surgeons is mandatory in Cranial Gunshot Injuries where extensive damage is linked to a higher mortality. KEY WORDS: Cranial gunshot inuuries, Cranial reconstruction, Maxillofacial reconstruction.

Maxillary fungus ball in a diabetic patient. An odontogenic origin.

INTRODUCTION: Fungus ball (FB) represents a granulomatous mass due to a fungal colonization which may disseminate and potentially lead to a systemic infection. Maxillary fungus ball is considered to be a complication of dental treatment and, according to relevant literature, it often stems from improper endodontic therapies. MATERIAL AND METHODS: The authors report the case of a 69-year-old caucasian woman with nasal respiratory distress and frequent sinusitis symptoms. According to clinical and radiological evidence, FESS surgery was planned, thus validating FB diagnostic hypothesis. CONCLUSIONS: Fungal infection should always be considered in patients with sinusitis and previous root canal theraphy. Misdiagnosis can lead to severe complications. Surgical removal seems to be effective and resolutive. KEY WORDS: Endoscopic surgery, Fungus Ball, Maxillary sinusitiss.

Cervical spine epidural abscess: experience with microsurgical treatment in eight cases.

OBJECT: The authors report a series of eight consecutive cases in which epidural abscesses in the cervical spine were treated by microsurgery without arthrodesis, including two cases of concomitant pyogenic and tubercular infection. METHODS: The authors used a minimally invasive surgical approach consisting of single-level anterior microsurgical discectomy and drainage of the epidural abscess via a silicone catheter, and then initiated antibiotic therapy. At follow-up examination (mean duration 39 months), six patients exhibited complete recovery and two suffered from minor residual deficits. In all cases, spontaneous vertebral fusion occurred. Sagittal alignment was maintained in seven patients, and in one there was slight asymptomatic kyphosis. In two patients, tubercular and pyogenic infections were found. Prior intervention for dental infection was recorded in four cases. CONCLUSIONS: In the absence of preoperative spinal instability, microsurgical drainage of the abscess followed by specific antibiotic therapy resulted in spinal cord decompression and neurological recovery, thereby facilitating spontaneous fusion and vertebral stability. The presence of combined tubercular and pyogenic infections of the cervical spine should be considered, especially in patients whose immune systems are depressed.
