Augmented reality-guided osteotomies for simulated mandibular reconstruction with fibular bone using virtual cutting guides and 3D navigation.

In the last decades, maxillomandibular reconstruction has been revolutionised by the use of free flaps and virtual surgical planning technologies. However, the currently available applied physical cutting guides provide no intraoperative flexibility, and adjustments based on intraoperative findings are not possible. A novel augmented reality (AR)-guided technique is presented that allows for quick intraoperative surgical planning adaptations.

Visor flap: A solution for the reconstruction of large skin defects on the frontal and parietal parts of the skull.

Background: Reconstruction of skin defects after oncological surgery for a cutaneous squamous cell carcinoma is often mandatory to facilitate adjuvant treatment and/or to prevent chronic wound problems. Some of the most challenging regions to reconstruct after resection of a skin tumor are the frontal and parietal parts of the skull.

Methods: This article describes three patients with large skin defects after oncological surgery that were reconstructed with the use of a (hemi) visor flap.

Pharyngo-cervicospinal fistula with destructive osteomyelitis after laryngopharyngectomy and radiotherapy, managed successfully with a vascularized fibula free flap.

Total laryngectomy is an operation mainly employed in recurrent laryngeal and hypopharyngeal carcinoma after previous radiotherapy. The most feared complication after this procedure is a pharyngocutaneous fistula. An extremely rare complication is the development of osteomyelitis of the cervical spine, which is associated with high rates of neurological impairment and epidural empyema, often requiring surgical treatment.

Sentinel node identification in laryngeal and pharyngeal carcinoma after flexible endoscopy-guided tracer injection under topical anesthesia: A feasibility study.

Background: The aim of this study was to investigate the feasibility of flexible endoscopy-guided tracer injection for sentinel lymph node (SLN) identification in patients with laryngeal and pharyngeal carcinoma.

Methods: Sixteen cT1-4N0-2M0 patients with laryngeal or pharyngeal carcinoma underwent intra- and peritumoral [ Tc]Tc-nanocolloid injections after topical anesthesia under endoscopic guidance. SPECT-CT scans were performed at two time points.

Effect of elective neck dissection versus sentinel lymph node biopsy on shoulder morbidity and health-related quality of life in patients with oral cavity cancer: A longitudinal comparative cohort study.

Objective: To research the difference in shoulder morbidity and health-related quality of life between patients with cTN0 oral cavity squamous cell carcinoma that undergo either elective neck dissection (END) or a sentinel lymph node biopsy (SLNB) based approach of the neck.

Materials And Methods: A longitudinal study with measurements before surgery, 6 weeks, 6 months, and 12 months after surgery. Shoulder morbidity were determined with measurements of active range of motion of the shoulder and patient-reported outcomes for shoulder morbidity (SDQ, SPADI) and health-related quality of life (HR-QoL) (EQ5D, EORTC-QLQ-HN35).
