Background: Craniofacial resection is the established "gold standard" for surgical treatment of tumors affecting the anterior skull base.
Methods: This study analyzed 308 patients (220 males, 88 females) who had undergone craniofacial resection for sinonasal neoplasia with up to 25-year follow-up.
Results: An overall actuarial survival of 65% at 5 years and 47% at 10 years was found for the cohort as a whole. For patients with malignant tumors, the 5-year actuarial survival was 59%, falling to 40% at 10 years. For patients with benign pathology, the actuarial survival was 92% at 5 years falling to 82% at 10 years. Statistical analysis again identified brain involvement, type of malignancy, and orbital involvement as the 3 most significant prognostic factors.
Conclusion: Analysis of one of the largest single institution cohorts over a 25-year period provides a baseline against which other approaches such as an entirely endoscopic skull base resection must be judged.

Background: Sinonasal malignancies, in which squamous cell carcinomas are the most common are rare and difficult to treat given the location and anatomical structures involved. Sinonasal malignancies often present late due to non-specific and benign symptoms. Partial resections are often associated with poorer outcomes [1].

Objectives: To assess the usefulness of sentinel lymph node biopsy (SLNB) in patients with early-stage oral squamous cell carcinoma (OSCC).
Materials And Methods: Seventy-five patients (mean age 62 years) diagnosed with cT1-2 N0 underwent SLNB with Tc, lymphoscintigraphy/SPECT-CT, and gamma probe detection with intraoperative histological examination of the resected sentinel lymph nodes (SLNs). Elective neck dissection was performed during the same surgical procedure of primary tumor resection when malignant deposits were detected microscopically.

The coexistence of fibrous dysplasia and aneurysmal bone cyst in the craniofacial region is extremely rare. This article presents a unique case involving the skull base, diagnosed using computed tomography and magnetic resonance. Imaging revealed a characteristic expansile mass with a ground-glass appearance alongside cystic areas exhibiting fluid-fluid levels, indicative of fibrous dysplasia and aneurysmal bone cyst.

Tumor-induced osteomalacia (TIO) is a rare paraneoplastic syndrome caused by hypersecretion of fibroblast growth factor 23 (FGF23) by typically benign phosphaturic mesenchymal tumors (PMTs). FGF23 excess causes chronic hypophosphatemia through renal phosphate losses and decreased production of 1,25-dihydroxy-vitamin-D. TIO presents with symptoms of chronic hypophosphatemia including fatigue, bone pain, weakness, and fractures.
