Background/Objectives: Virtual surgical planning (VSP) and CAD/CAM technologies have revolutionized complex maxillofacial reconstruction. While high-resolution imaging is critical for these workflows, the specific clinical impact of photon-counting computed tomography (PCCT) remains to be fully established. This prospective pilot study evaluates the feasibility and clinical utility of integrating PCCT into the preoperative planning and surgical workflow of complex maxillofacial reconstructive cases. Methods: This feasibility study included ten patients requiring complex maxillofacial reconstruction with microvascular free flaps. All underwent preoperative imaging with photon-counting CT. Primary endpoints included clinical assessment of osseous invasion, reliability of donor-site vascular mapping from a single acquisition, and compatibility of PCCT datasets with VSP/CAD-CAM platforms. Secondary endpoints included resection margin status, flap survival, and short-term oncologic outcomes. Results: PCCT provided high-resolution visualization of cortical and medullary bone, enabling detailed assessment of tumor-related osseous involvement. In selected cases, findings supported refinement of resection planning when prior imaging had been inconclusive. Spectral reconstructions reduced metal artifacts and facilitated precise segmentation for multi-segment osteotomies. Donor-site vascular anatomy was successfully evaluated within the same scan, supporting operative planning without additional imaging. PCCT datasets were fully compatible with the virtual surgical planning (VSP) software used in this study (CMX Portal, version 2.6.1158, Medartis AG, Basel, Switzerland; or ProPlan CMF, version 5.7.8.025, Materialise NV, Leuven, Belgium) in all cases (100%). Reconstruction was completed successfully in all patients, with 100% flap survival and R0 margins in all malignant cases. No technical failures occurred during imaging transfer or CAD/CAM fabrication. Conclusions: The integration of PCCT into the surgical workflow proved technically feasible and clinically impactful. This pilot data supports its potential to enhance surgical precision and preoperative planning in complex jaw reconstruction.

Wind instrument performance requires sustained and repetitive increases in intrathoracic and pharyngeal pressures, which may lead to rare but clinically relevant anatomical alterations of the upper aerodigestive tract. We report the case of a 46-year-old male semi-professional wind instrument player who developed massive hypopharyngeal dilatation and cervical lung herniation as a consequence of long-term, high-pressure musical activity. Dynamic imaging performed during instrument playing demonstrated marked hypopharyngeal expansion and herniation of the lung apices into the cervical region, highlighting the importance of individualized diagnostic strategies that replicate patient-specific triggers. Multidisciplinary evaluation integrating otorhinolaryngology, thoracic surgery, radiology, and pulmonology led to a personalized risk assessment and the recommendation to cease wind instrument performance in order to prevent potentially life-threatening complications, such as pneumothorax. This case illustrates how personalized diagnostic approaches and tailored clinical decision-making are essential in managing rare occupational conditions. A comprehensive review of the literature is provided, with a focus on individualized risk factors, diagnostic strategies, and personalized treatment concepts relevant to precision medicine.

An 80-year-old man with hypercalcemia and hyperparathyroidism was suspected of having a parathyroid adenoma, which was localized on [ ¹⁸ F]F-choline-PET/CT. Still, after surgical removal of the suspected adenoma with an intraoperative parathyroid hormone decrease of >50%, severe hypercalcemia recurred quickly. A repeated [ ¹⁸ F]F-choline-PET/CT raised suspicion of a single contralateral parathyroid adenoma or multiglandular disease. Given the inconclusive findings, a histological reassessment of the suspected parathyroid adenoma showed the presence of a singular vessel invasion, which alerted the diagnosis to parathyroid carcinoma. An additionally performed [ ¹⁸ F]FDG-PET/CT revealed a liver lesion and MRI confirmed multiple liver metastases, which could not be seen on [ ¹⁸ F]F-choline-PET/CT.
