Sentinel Lymph Node Detection in Early-Stage Oral Squamous Cell Carcinoma Using Magnetic Resonance Lymphography: A Pilot Study.

To assess the efficacy of magnetic resonance (MR) lymphography with gadobutrol contrast for sentinel lymph node (SLN) mapping in early-stage oral squamous cell carcinoma (OSCC). This pilot study compared the identification of SLNs by MR lymphography using a gadolinium-based contrast agent (gadobutrol) to conventional [Tc]Tc-nanocolloid lymphoscintigraphy (including single-photon emission computed tomography/computed tomography (SPECT/CT)) in 10 early-stage OSCC patients undergoing SLN biopsy. The patients initially underwent conventional lymphoscintigraphy following the peritumoral administration of indocyanine green [Tc]Tc-nanocolloid (120 megabecquerel; ~0.

Three-year trajectories and associated factors of fear of cancer recurrence in newly diagnosed head and neck cancer patients: a longitudinal study.

Purpose: Limited data exists on the long-term course of fear of cancer recurrence (FCR) in head and neck cancer (HNC) patients. One in five patients was found to experience persistent high FCR in the first months after diagnosis. This study assessed the 3-year trajectories and associated factors of FCR in newly diagnosed HNC patients.

Accuracy of augmented reality navigated surgery for placement of zygomatic implants: a human cadaver study.

Purpose: Placement of zygomatic implants in the most optimal prosthetic position is considered challenging due to limited bone mass of the zygoma, limited visibility, length of the drilling path and proximity to critical anatomical structures. Augmented reality (AR) navigation can eliminate some of the disadvantages of surgical guides and conventional surgical navigation, while potentially improving accuracy. In this human cadaver study, we evaluated a developed AR navigation approach for placement of zygomatic implants after total maxillectomy.

Exploring Potential Orbital Metastatic Pathways in Sinonasal Mucosal Melanoma: A Case Report.

The following case potentially provides insight into the mechanisms of lymphogenic metastasis in sinonasal cancer. A 63-year-old patient who presented with progressive diplopia and left-sided periocular pain was diagnosed with a cT4bN0M0 mucosal melanoma of the ethmoid sinus. She underwent a combined endonasal and transcranial tumor resection, and an orbital exenteration.
