Does Zygomatic Complex Symmetry Differ Between Healthy Individuals and Surgically Treated Patients Using Intraoperative 3-Dimensional Cone Beam Computed Tomographic Imaging?

Purpose: Reconstruction of symmetry after zygomaticomaxillary complex (ZMC) fractures is essential for esthetic appearance as well as function. Therefore, this study aimed to analyze whether bony facial symmetry in patients surgically treated for unilateral ZMC fractures via intraoperative imaging differs from that of healthy individuals.

Patients And Methods: Retrospective and cross-sectional radiographic measurements of patients treated for unilateral ZMC fractures via intraoperative cone beam computed tomography (CBCT) were performed to evaluate the postoperative ZMC symmetry.

Virtual planning, simultaneous dental implantation and CAD/CAM plate fixation: a paradigm change in maxillofacial reconstruction.

Prosthetic rehabilitation in patients undergoing reconstructive surgery using vascularized free flaps is challenging, and functional rehabilitation of the patient with a fixed prosthesis is rare. Virtually planned maxillofacial reconstruction including simultaneous dental implantation according to the prosthodontic ideal position of the implants could further enhance dental rehabilitation. The data of 21 patients undergoing fibula free flap reconstructive surgery with CAD/CAM patient-specific reconstruction plates during the years 2015-2018 were analysed, including the applicability of the virtual plan, flap survival, duration of surgery, ischemia time, simultaneous dental implantation, implant exposure, and postoperative complications.

The influence of lymph node ratio on survival and disease recurrence in squamous cell carcinoma of the tongue.

This study was performed to report the outcomes of patients with oral squamous cell carcinoma (OSCC) of the tongue over a 10-year period with the aim of testing the hypothesis that the lymph node ratio (LNR) has a significant influence on loco-regional recurrence. The charts of 227 patients with OSCC of the mobile tongue treated at the University Hospital of Zurich from 2003 to 2012 were screened. Following the application of the exclusion criteria (prior chemotherapy, radiotherapy, or surgery, perioperative death, N3 disease, unresectable disease, synchronous second primary, no signed informed consent, and follow-up <3years), prospective data were collected and a retrospective analysis performed for 88 of these patients who were treated with selective neck dissection.

Sentinel lymph node biopsy for early stage tongue cancer-a 14-year single-centre experience.

This study was performed to report the usage of sentinel lymph node biopsy (SLNB) in clinical stage I or II tongue cancer patients with cN0 necks seen over a 14-year period. Data were collected prospectively, and a retrospective analysis was performed of 41 patients with early stage oral squamous cell carcinoma of the tongue and a cN0 neck. Sentinel lymph node (SLN)-positive patients underwent elective neck dissection, whereas SLN-negative patients were kept under careful observation.

Adenosine arrests breast cancer cell motility by A3 receptor stimulation.

In neutrophils, adenosine triphosphate (ATP) release and autocrine purinergic signaling regulate coordinated cell motility during chemotaxis. Here, we studied whether similar mechanisms regulate the motility of breast cancer cells. While neutrophils and benign human mammary epithelial cells (HMEC) form a single leading edge, MDA-MB-231 breast cancer cells possess multiple leading edges enriched with A3 adenosine receptors.
