Current trends of practical issues concerning micropapillary thyroid carcinoma: The Korean Society of Thyroid-Head and Neck Surgery.

Although several thyroid associations have published various guidelines, controversies especially in cases of micropapillary thyroid cancer (MPTC) still exist. This survey was designed to collect information about diagnostic tests and treatments performed on patients with MPTC and help identify current trends in thyroid surgery.We developed questionnaires about the management methods for MPTC, which were used to identify factors related to indications of fine needle aspiration (FNA), type of surgery, and central lymph node dissection (CLND).

The Effect of Polydeoxyribonucleotide on Ischemic Rat Skin Flap Survival.

Polydeoxyribonucleotide (PDRN) has multiple vascular actions such as angiogenesis and production of a vascular endothelial growth factor (VEGF) through the adenosine A2 receptor stimulation. We applied PDRN on the ischemic flap of rat back and investigated whether it enhances the skin flap survival. A total of 28 Sprague-Dawley rats were divided into 3 groups, namely, PDRN group, control group 1 (no treatment), and group 2 (phosphate-buffered saline injection).

Evaluation of the efficacy of microsurgical practice through time factor added protocol: microsurgical training using nonvital material.

Purpose: The evaluation of microsurgical technique is often done in an attempt to enhance the skills of surgeons. However, it varies depending on the institution or supervisors. According to some of the research done so far, there are many institutes that enable surgeons to train themselves with enough time but are confronted with some other limiting factors.

A three-dimensional analysis of the relationship among lower facial width, bony width, and masseter muscle volume in subjects with prominent mandible angles.

Despite the fact that a face with a square appearance is determined by surface anatomic features, skin surface parameters and their relationship with inner anatomic features have not been evaluated owing to the challenge of accurately and consistently measuring skin landmarks.We introduce 2 surface distances of the lower face obtained from images of skin and bone thresholds from three-dimensional computed tomographic scans; these were realigned in identical positions using the Frankfurt horizontal plane. The selected parameters were skin surface (LFOP) and bony width (MOP) of the occlusal plane level, skin surface (LFBP) and bony width (MBP) of the bigonial plane level, masseter volume (MV), and soft tissue thickness.

Transport disc distraction osteogenesis for the reconstruction of a calvarial defect.

Purpose: Reconstruction of bone defects is possible through distraction osteogenesis using small bone transport discs. The aim of this study was to evaluate the usability of transport disc distraction osteogenesis (TDDO) in the reconstruction of skull defects in an animal experiment.

Methods: Eleven mongrel female dogs were used.

Surgical correction of pseudoainhum in chronic epidermolysis bullosa: a case report.

Pseudoainhum is a rare condition of unknown aetiology that is characterised by the presence of constriction bands of extremities due to a variety of underlying causes that progress to irreversible damage and auto-amputation of the affected digit. Epidermolysis bullosa is a group of disorders characterised by extremely fragile skin and recurrent blister formation resulting from minor mechanical trauma. The association of epidermolysis bullosa with other hand defects, such as hand contracture and pseudosyndactyly, have been reported; however, ainhum-like digital constriction bands have not been reported in association with this disorder.
