Cage-screw and anterior plating combination reduces the risk of micromotion and subsidence in multi-level anterior cervical discectomy and fusion - A finite element study
Anterior cervical discectomy and fusion (ACDF) is widely used to treat patients with spinal disorders, where the cage is a critical component to achieve satisfactory fusion results. However, it is still not clear whether a cage with screws or without screws will be the best choice for long-term fusion as the micromotion (sliding distance) and subsidence (penetration) of the cage still take place repeatedly.

Cervical Paraspinal Muscle Fatty Degeneration Is Not Associated with Muscle Cross-sectional Area: Qualitative Assessment Is Preferable for Cervical Sarcopenia.
CONCLUSION: Because our study demonstrates minimal association between paraspinal cross-sectional area and fatty infiltration of the cervical paraspinals, we recommend that physicians use the proven qualitative assessment of paraspinal fatty infiltration during preoperative evaluation of patients who are candidates for ACDF. Future studies investigating the relationship between cervical paraspinal cross-sectional area and patient-reported outcomes after ACDF are necessary to lend greater strength to this recommendation.

Right vertebral artery entering the third transverse foramen diagnosed by magnetic resonance angiography: a report of two cases
AbstractThe vertebral artery (VA) usually enters the sixth transverse foramen (TF). The VA sometimes enters the fifth, and rarely enters the fourth or seventh TF. Reports describing a VA entering the third TF, identified by anatomical dissection or computed tomography angiography, are extremely rare. We herein report two cases in which magnetic resonance (MR) angiography showed the right VA entering the third TF. Coronal reformatted MR angiography source images were useful for identifying the level at which the VA entered the TF. Because the anomalous VA takes an anterior course, it poses a risk during anterior neck surger...

Changes in cervical range of motion following anterior cervical discectomy with fusion - preliminary results.
CONCLUSIONS: ACDF reduces the total ROM of the cervical spine in the sagittal plane. This change occurs by reducing the neck extension, and its severity depends on the length of the spondylodesis. In patients without ASDeg after ACDF, the mobility of the level above the stabilisation decreases. The occurrence of ASDeg is associated with a higher postoperative ROM of the segment located above the spondylodesis.

What is the role of sentinel lymph node biopsy in the management of oral cancer in 2020?
AbstractApproximately 70 –80% of patients with cT1-2N0 oral squamous cell carcinoma (OSCC) ultimately prove to have no cancer in the cervical lymphatics on final pathology after selective neck dissection. As a result, sentinel lymph node biopsy (SLNB) has been adopted during the last decade as a diagnostic staging method to intelligently identify patients who would benefit from formal selective lymphadenectomy or neck irradiation. While not yet universally accepted, SLNB is now incorporated in many national guidelines. SLNB offers a less invasive alternative to elective neck dissection (END), and has some advant...

Completion of radical hysterectomy does not improve survival of patients with cervical cancer and intraoperatively detected lymph node involvement: ABRAX international retrospective cohort study
The management of cervical cancer patients with intraoperative detection of lymph node involvement remains controversial. Since all these patients are referred for (chemo)radiation after the surgery, the key decision is whether radical hysterectomy should be completed as originally planned, taking into account an additional morbidity associated with extensive surgical dissection prior to adjuvant treatment. The ABRAX study investigated whether completing a radical uterine procedure is associated with an improved oncological outcome of such patients. (Source: European Journal of Cancer)

Surgical anatomy of the submental artery perforator flap and assessment for application in postoperative reconstruction following oral cancer surgery: a prospective clinical study
The submental artery perforator flap (SMAPF) has an elongated pedicle, allowing good cosmetic outcomes to be achieved following oral reconstruction surgery. The improper dissection of perforators often leads to a vascular flap crisis. To avoid this, some surgeons choose to carry amounts of connective tissue around the pedicle. However the inclusion of connective tissue on the pedicle raises concerns about oncological safety. A surgical anatomical study of the submental vessel patterns and subdivisions of the cervical level I lymph nodes was conducted on 33 patients with primary oral cancer who underwent reconstruction with...

ConclusionAlthough low molecular weight heparin was used much less frequently than regular heparin, it was associated with a lower incidence of transfusion compared with aspirin and regular heparin. All three anticoagulants were associated with similar incidence of VTE and hematoma. Varying subgroup-specific VTE risks may further inform future studies to identify patients expected to benefit the most from chemical thromboprophylaxis. (Source: Canadian Journal of Anesthesia)
