Volumetric Analysis of Navigation-Guided Orbital Decompression in Graves' Orbitopathy: A Case Report.

Graves' orbitopathy (GO) is a debilitating autoimmune disorder that may require surgical orbital decompression in severe cases with risk of proptosis and optic neuropathy. This report presents a case treated with navigation-assisted three-wall orbital decompression, planned with preoperative imaging and assessed using postoperative analysis. Intraoperative navigation enabled precise localization of critical structures, improving osteotomy execution.

Implant-Supported Oral Rehabilitation in Head and Neck Cancer Patients: A 20-Year Single-Center Study (2005-2024).

Oral cancer resection often leads to maxillofacial defects and dentition loss, compromising patients' quality of life. Implant-supported prosthetic rehabilitation offers a reliable solution to restore function, though factors such as bone reconstruction, radiotherapy, and timing of implant placement (immediate vs. delayed) may influence outcomes.

Extraenteric Malignant Gastrointestinal Neuroectodermal Tumor of the Neck: A Diagnostic Challenge.

Malignant gastrointestinal neuroectodermal tumor (MGNET) and clear cell sarcoma (CCS) of soft tissue represent related, extremely rare, malignant mesenchymal neoplasms. Both entities are genetically characterized by the same molecular alterations, fusions. Malignant gastrointestinal neuroectodermal tumor has significant morphological overlap with CCS, although it tends to lack overt features of melanocytic differentiation.

Microsoft HoloLens 2 vs. tablet-based augmented reality and 3D printing for fronto-orbital reconstruction of craniosynostosis: a case study.

Background: Craniosynostosis is a congenital condition characterized by the premature fusion of cranial sutures, leading to potential complications such as abnormal skull growth, increased intracranial pressure, and cognitive delays. Traditionally, open cranial vault reconstruction (OCVR) has been used to treat this condition. However, it is highly subjective and greatly dependent on the surgeon's expertise, which can lead to residual deformities and the need for reoperation.

Maxillary Jaw-in-a-Day: The Role of Point-of-Care Manufacturing and Implant Stability Quotient in Centrofacial Chondrosarcoma.

Chondrosarcoma is a rare malignant tumor of epithelial origin, with fewer than 0.1% of cases affecting the nasal septum. Maxillofacial oncological surgery presents significant challenges, particularly in maxillary reconstruction, often requiring complex rehabilitation.

Proportional Condylectomy for the Treatment of Unilateral Condylar Hyperplasia With Maloclussion: Role of Point-of-Care Manufacturing Surgical Guides and Intraoperative Computed Tomography to Avoid Secondary Orthognatic Surgery.

Condylar hyperplasia (CH) is a complex, usually unilateral pathology affecting the jaw, leading to facial asymmetry and malocclusion. Its etiology is unclear, with potential links to endocrine disorders, trauma, and genetic factors. Unilateral condylar hyperplasia (UCH) typically presents in young patients but can occur at any age.

Aggressive Late Recurrence of a Calcifying Epithelial Odontogenic Tumor: Surgical Refinements Based on New Technologies.

A calcifying epithelial odontogenic tumor is a rare, benign odontogenic neoplasm. Surgical treatment is the option, and late recurrence is very rare. Radiologically, the lesions are commonly present scattered calcifications.

Contemporary Treatment of Silent Sinus Syndrome: A Case Report and Literature Review.

Silent sinus syndrome is a rare clinical entity affecting the maxillary sinus, characterized by ipsilateral enophthalmos and hypoglobus. Its etiology and pathophysiology are still debated. It is diagnosed by clinical examination and confirmed with computed tomography.

Dynamic Trends in Surgical Oromaxillofacial Trauma Epidemiology: A Comparative Study of Pre-COVID-19 and COVID-19 Periods in Tertiary Referral Hospitals in Madrid.

: The COVID-19 pandemic has induced profound societal and healthcare transformations globally. : This multicenter retrospective study aimed to assess potential shifts in the epidemiology and management of oromaxillofacial trauma requiring surgical intervention over a 1-year period encompassing the onset of the COVID-19 pandemic, in comparison to the preceding year. The parameters investigated included age, sex, injury mechanisms, fractured bones, and treatment modalities.

Orbital Cellulitis and Frontal Epicranial Empyema Secondary to Pansinusitis: A Case Report.

Orbital cellulitis is a relatively uncommon complication of sinusitis. Its association with intracranial complications is rare. We present the case of a 36-year-old patient with no associated risk factors who presented with a four-day history of headache, periorbital inflammation, suppuration, and necrosis.

Parascapular Flap for Severe Hidradenitis Suppurativa.

Hidradenitis suppurativa is a chronic inflammatory disease which affects apocrine glands and hair follicles of the skin, primarily in the axillary and groin regions. This condition can be highly debilitating, causing painful lesions and a negative psychological impact on patients. While medical and minimally invasive treatments are available, surgical intervention may be necessary for severe cases.

Cervical Lymphadenopathies as Unusual Presentations of Erdheim-Chester Disease: The Need for Knowledge for Diagnosis and Treatment.

The appearance of cervical adenopathies can occur in many pathologies in a non-specific manner; Erdheim-Chester disease (ECD) is characterized by xanthogranulomatous and xanthomatous infiltration of different tissues with numerous foamy histiocytes. Bone lesions are frequent and radiological features are pathognomonic for diagnosis, but lymph node involvement is exceptional and is not a form of presentation reported in the literature. Recurrent BRAFV600E mutation and others have been discovered in recent years.

Mandibular Reconstruction With Fibula Flap and Dental Implants Through Virtual Surgical Planning and Three Different Techniques: Double-Barrel Flap, Implant Dynamic Navigation and CAD/CAM Mesh With Iliac Crest Graft.

Introduction: Vertical discrepancy between the fibula flap and the native mandible results in difficult prosthetic rehabilitation. The aim of this study was to evaluate the outcomes of 3D reconstruction of the mandible in oncologic patients using three different techniques through virtual surgical planning (VSP), cutting guides, customized titanium mesh and plates with CAD/CAM technology, STL models and intraoperative dynamic navigation for implant placement. Material and methods.

Preoperative Doppler Ultrasonography Allen Test for Radial Forearm Free Flap in Oral Cancer Reconstruction: Implications in Clinical Practice.

The Radial Forearm Free Flap (RFFF) is one of the most widely used microsurgical flaps for intraoral reconstruction. Although the Clinical Allen Test (CAT) is the most widely used preoperative diagnostic method with which to study the distal patency of the hand prior to the use of RFFF, several authors have reported potentially preventable serious vascular complications. This study included 87 consecutive patients with cancer of the oral cavity and RFFF as the flap of choice who were treated between 2010 and 2020, and compares the results of the Clinical Allen Test (CAT), the Doppler Allen Test (DAT) and the Surgical Allen Test (SAT).
