Laser laryngeal microsurgery is currently the primary method of treatment of various laryngeal diseases. The development of laryngeal microsurgery came from the introduction of a small spot $CO_2$ laser micromanipulator and more precise microlaryngeal instruments. $CO_2$ laser laryngeal microsurgery has enabled very precise surgery because it has small focus size and hemostatic effect. There are some limitations to the use of the $CO_2$ Laser such as adjacent tissue damage and vocal fold scarring. These problems can be minimized through understanding the mechanisms by which lasers function and correctly manipulating the parameters under a surgeon's control. We should also recognize the safety of $CO_2$ laser for the surgeon to precisely perform the procedure.

Although modern medicine has made great strides in the management of burn injuries, associated complications such as pain, infection, dyspigmentation, and scarring have yet to be fully dealt with. Although skin grafting and meshing are routinely performed on burn patients, this method poses a risk for adverse effects. Activated autologous platelet-rich plasma (aaPRP), which is increasingly used in the field of plastic surgery, contains growth factors beneficial for wound regeneration. Seven cases of burns with varying severity and conditions that were treated with intralesional subcutaneous injection and intravenous aaPRP are presented and discussed herein. This case series indicates that subcutaneous and intravenous aaPRP is a safe procedure with the potential to be an alternative when skin grafting cannot be done or as an adjunct treatment to skin grafting.

Prostaglandin (PG) $E_2$ is an important mediator of skin wound healing without excessive scarring and gastric ulcer healing. However, $PGE_2$ has a short lifetime in vivo because it is metabolized rapidly by 15-hydroxyprostaglandin dehydrogenase (15-PGDH). Ethanol extract of Eriobotryae folium (EFEE) elevated intracellular and extracellular $PGE_2$ levels in HaCaT cells and inhibited 15-PGDH ($ED_{50}$ : $168.4{\mu}g/mL$) with relatively low cytotoxicity ($IC_{50}$ : $250.0{\mu}g/mL$). Real-time PCR analysis showed that mRNA expression of cyclooxygenase (COX)-1 and COX-2 enzymes were increased and prostaglandin transporter (PGT) was decreased in HaCaT cells by EFEE. Moreover, wound healing effect of EFEE ($168.4{\mu}g/mL$) was comparable to that of TGF-${\beta}1$ (300 pg/mL) as a positive control. These results demonstrate that EFEE may be valuable therapeutic materials for the treatment of $PGE_2$ level dependent diseases.

Objectives : It has been reported that CG was effective in decreasing injury to neural tissues. To investigate neural responses in the injured spinal cord, an extract of CG was examined to determine its effect on neural responses in the injured spinal cords of rats. Methods : After CG treatment was applied to the spinal cord of rats given a contusion injury, the re-growth responses of injured neural tissues and corticospinal tract axons was observed by measuring the number of GAP-43, Cdc2, and phospho-Erk1/2 proteins, CST axons, GFAP-stained astrocytes, and Glial scarring in the injured spinal cord. Results : Levels of GAP-43, Cdc2, and phospho-Erk1/2 proteins were found to have increased in the injured spinal cord region. The number of GFAP-stained astrocytes also increased within and around the injury cavity. Glial scarring, which was identified by CSPG immunofluorescence staining, was reduced by CG treatment. Anterograde tracing by Dil dye showed that the elongation of the CST axons in the dorso-medial white matter area was almost completely prevented at the injury site. Collateral sprouting was observed in the spinal cord rostrally close to the injury site, and CG treatment further increased axonal arborization in the corresponding region. In vivo migration of CST axons and astrocytes using an implanted polymer tube system showed more of an increase in enhanced migration of axons and astrocytes in CG-treated group compared to the injury control group. Conclusions : These results suggest that CG activated neural responses - including astrocyte migration - and promotes axonal regenerative activity in the injured spinal cord area.

Radiofrequency thermocoagulation(RF) techniques are safe and effective methods as compared to neurodestructive procedure. Other advantages are: ability to perform RF lesions under local or sedative anesthesia, rapid recovery period, low incidence of morbidity and mortality, ability to repeat RF lesions, and leaves no significant scarring. We performed C2 ganglionotomy by RF lesion generator on a patient, suffering post-traumatic occipital neuralgia, as the patient did not respond to conservative therapies such as: trigger point injection, TENS, cryotherapy and stretch, occipital nerve block, C2 ganglion block. Prognostic nerve block was performed usng local anesthetics. Excellent effect was conformed before C2 ganglionotomy. This procedure was performed under fluoroscopy. Type RCK-2A Rosomoff Cordotomy kit was used to stabilize the head and neck. Postoperatively, the patient was free of occipital pain and head motions no longer triggered pain. To date, the patient remains symptom free except for some cervical discomfort.

Objective : Acne is very common disease, it can leave permanent scars. However, there are few reports about it in oriental medicine academia. This study performed to evaluate the effect of reconstruction of skin scars and auto microneedle therapy system on acne scars. Methods : Six patients were treated by using reconstruction of skin scars and auto microneedle therapy system. We compared the degree of treatment of acne scars on pre and post case photos and Qualitative Global Acne Scarring Grading System(QGASC). Satisfaction degree were asked from the patients. Results & Conclusion : After comparing case photos and QGASC, observing patients satisfaction, it can be considered that reconstruction of skin scars and auto microneedle therapy system to be valid acne scars treatment.

Traumatic lacerations are common in the orofacial region as a result of accidents. Due to the frequent movement of the skin around the mandible, scars in that area are more likely to widen or become hypertrophic. Treatment of facial laceration was performed on three patients and followed by regular check-up. It was discovered that the scars have become hypertrophic, so steroid injections were used. The results were satisfactory with the decrease in sizes and hardnes of the scar. Facial scarring is a particularly distressing phenomenon and has always been a challenge to treat as the scars are more likely to widen or become hyphertrophied due to the frequent movement of the muscle in the facial area. We confirmed that the positive effect of steroid on hypertrophic scars. So, we suggest that proper treatment and periodic follow-up, adjuvant treatments especially steroid injection is necessary in patients with lacerations.

Alopecia is usually presented as patchy, no scarring hair loss. It seems to be a hormonal imbalance or an immune mediated disease, whereas genetic predisposition, environmental and psychological factors may be involved in its etiology. Many treatments of alopecia disease have been widely applied, but their side effects are also well known. The purpose of this study is to demonstrate efficacy and safety of a food supplement containing medicinal plant extracts, amino acid and vitamin complex on the prevention of hair loss in human. A total of 20 subjects aged between 29-50 years with subjective hair loss complaint were recruited for this study. Each subject took 1 g/day supplement for 3 months. 5-Scale self-assessment test, hair loss count and measurement of hair thickness were conducted to evaluate the effect of supplement on the improvement of hair loss. Subjective hair loss was decreased and hair damage and thickness were improved in self-assessment test. After 3 months of supplementation, hair loss counts were decreased (P<0.05) while hair thickness was increased(P<0.001) significantly. There was no side effect observed during the study. These results suggest that the supplement consist of medicinal plant extracts, amino acid and vitamin complex might be useful for the improvement of hair loss with no significant side effects.
