Background Human bite wounds in emergency department need evaluation in regard of reconstruction. These are due to occlusive bite injuries over face. Most commonly, human bites over face involve ear and nose, and may lead to avulsion injury. Defects over nose can be reconstructed immediately after debridement or delayed till the wound heals and scar becomes supple. Thorough wash and lavage with broadspectrum antibiotic cover has utmost importance in preventing cartilage infection. Methods We report 20 cases of human bite injuries over nose who presented to us in emergency department between 2018 and 2020. At the time of presentation the wound was assessed for closure. If not possible, patient was planned for delayed reconstruction after 3 months. In case delayed reconstruction was planned, the skin and nasal mucosa were approximated at first presentation. The patients underwent paramedian forehead flap after recreation of defect with conchal cartilage graft. Second stage of flap detachment and insetting was done after 3 weeks. After three weeks of second stage, third stage of flap thinning was done. Patients were followed for 3-6 months and subjective satisfaction was noted. Results Nineteen patients underwent delayed staged reconstruction with paramedian forehead flap and one underwent primary wound closure. The flap survival was 100%. The patient satisfaction was excellent in most cases. Conclusion We recommend delayed reconstruction for human bite nasal injuries. For reconstruction, paramedian forehead flap with conchal cartilage graft, if required, provides excellent reconstructive option with good contour and color match and minimal donor site scar.

Objective : Cricothyrotomy and tracheostomy are performed by physicians in various disciplines. It is important to know the comprehensive anatomy of the laryngotracheal region. Hemorrhage, esophageal injury, recurrent laryngeal nerve injury, pneumothorax, hemothorax, false passage of the tube and tracheal stenosis after decannulation are well known complications of the cricothyrotomy and tracheostomy. Cricothyrotomy and tracheostomy should be performed without complications and as quickly as possible with regards the patients' clinical condition. Methods : A total of 40 cadaver necks were dissected in this study. The trachea and larynx and the relationship between the trachea and larynx and the surrounding structures was investigated. The tracheal cartilages and annular ligaments were counted and the relationship between tracheal cartilages and the thyroid gland and vascular structures was investigated. We performed cricothyrotomy and tracheostomy in eleven cadavers while simulating intensive care unit conditions to determine the duration of those procedures. Results : There were 11 tracheal cartilages and 10 annular ligaments between the cricoid cartilage and sternal notch. The average length of trachea between the cricoid cartilage and the suprasternal notch was 6.9 to 8.2 cm. The cricothyroid muscle and cricothyroid ligament were observed and dissected and no vital anatomic structure detected. The average length and width of the cricothyroid ligament was 8 to 12 mm and 8 to 10 mm, respectively. There was a statistically significant difference between the surgical time required for cricothyrotomy and tracheostomy (p < 0.0001). Conclusion : Tracheostomy and cricothyrotomy have a low complication rate if the person performing the procedure has thorough knowledge of the neck anatomy. The choice of tracheostomy or cricothyrotomy to establish an airway depends on the patients' clinical condition, for instance; cricothyrotomy should be preferred in patients with cervicothoracal injury or dislocation who suffer from respiratory dysfunction. Furthermore; if a patient is under risk of hypoxia or anoxia due to a difficult airway, cricothyrotomy should be preferred rather than tracheostomy.

There are many residual nasal deformities following midface injury. The treatment of primary nasal deformities is delayed frequently due to several factors. And then, we usually perform the secondary nasal reconstruction. Autogenous bone is the material of choice for major nasal augmentation. It can be contoured appropriately and securely immobilized. It is rapidly incorporated as living tissue by the recipient bed. We used with iliac bone, contochondral graft and ear cartilage for secondary nasal augmentation and obtained the relatively fair results.

Laryngeal trauma is an uncommon injury but can be life-threatening event. So, early diagnosis is important for appropriate surgical management and better outcome. Because there have been some controversies about Initial airway management, appropriate diagnostic evaluation, operative indication and timing, operative technique, it is difficult to make a common management pathway in laryngeal trauma. A case of laryngeal trauma with thyroid cartilage and hyoid bone fracture is presented with a brief review of literature.

In the past several years the popularity of the motor cycle has produced an increasing incidence of the injuries to the larynx and trachea. Most of all on accidents come to death and survivors to the hospital are rare. Early diagnosis and to keep air way are necessary to initiate proper treatment in injury of upper air way. Meticulous apposition of mucous membrane and reconstitution of laryngeal skeleton are important. We experienced a rare case of 26 year old men with cricothyroidal transection after trauma. On Oct. 17, 1985, the patient struck his neck on baggage frame of truck when dropping from his motor cycle on sudden stop. Emergency tracheal intubation on distal segment of trachea was accomplished by otolaryngologist in a local clinic. He was transferred to our hospital. Exploration 2 hours later revealed complete separation of cricoid cartilage from thyroid cartilage. The recurrent laryngeal nerve could not be identified. Anastomosis of thyroid and cricoid was accomplished and Portex endotracheal tube was inserted as splint for 10 days. No stenosis developed. The air way appeared adequate for moderate physical activity though paramedian fixation of vocal cord paralysis. Postoperative follow-up course has been good after he discharged on POD 14 days.

Objectives: This study investigated the anti-osteoarthritic effects of Kyejiinsam-tang (hereinafter referred to KIT) on the monosodium iodoacetate (MIA)-induced osteoarthritis rats. Methods: Anti-oxidative effects of KIT were measured by scavenging activities of DPPH, reactive oxygen species (ROS) and nitric oxide (NO). Scavenging activities of anti-oxidation in lipopolysaccharide (LPS)-treated RAW 264.7 cells were also measured for inhibitory effects against the production of inflammatory mediators (tumor necrosis factor-${\alpha}$, interleukin-$1{\beta}$, interleukin-6). Osteoarthritis was induced in rats by injecting MIA in the knee joint. Rats were divided into a total of 4 groups (n=6). The normal group were not treated at all without inducing osteoarthritis whereas the control group were induced for osteoarthritis by MIA and oral medicated physiological saline per day. The positive comparison group was injected with MIA and after 7 days, 2 mg/kg of Indomethacin. The experimental group was injected with MIA and after 7 days was medicated with 34 mg/kg of KIT. Indomethacin and KIT were orally-medicated for each substance a total of 4 weeks, once per day. Weight-bearing on hind legs was measured every week after MIA injection. At the end of the experiment (5 weeks after MIA injection), micro CT (computed tomography)-arthrography and histopathological examinations on the articular structures of knee joint were performed. The effect on inflammatory cytokines and immunological cells in synovial fluid was measured. Volume of cartilage was measured by micro CT-arthrography. Injury to synovial tissue was measured by H & E (hematoxylin and eosin), Safranin-O immunofluorescence. Results: 1. Cytotoxicity against hFCs was insignificant. 2. KIT showed the potent full term for DPPH. 1. NO was significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and ROS was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 2. IL-6 and IL-$1{\beta}$ were significantly reduced by KIT (at 100, $200{\mu}g/m{\ell}$) and TNF-${\alpha}$ was also reduced, but not significantly, by KIT (at $200{\mu}g/m{\ell}$). 1. In hind legs weight-bearing measurement, level of weight increased. 2. Functions of liver and kidney were not affected. 3. IL-$1{\beta}$ was significantly reduced and TNF-${\alpha}$, IL-6 were also reduced but not significantly. 4. PGE2 (prostaglandin E2), LTB4 (leukotriene B4) were significantly reduced in the KIT group. 5. MMP-9 (matrix metalloproteinase-9), TIMP-1 (tissue inhibitor of metalloproteinases-1) and Osteocalcin were significantly reduced in the KIT group. 6. Destruction of cartilage on micro CT arthrography was reduced but had no significant differences. 7. Histopathologically, injury to synovial membrane of the KIT group was decreased and proteoglycan content of KIT group was increased. Conclusions: According to this study, Kyejiinsam-tang has inhibiting effect on the progression of arthritis in MIA-induced osteoarthritis rat. Kyejiinsam-tang has anti-oxidants and anti-inflammation effects, and is related to inhibiting the activity of inflammatory cytokine and injury of volume in cartilage.
