소병준 ( Byoung Joon So ),김일환 ( Il Hwan Kim ) 대한피부과학회 2014 대한피부과학회지 Vol.52 No.8

Background: An ingrown nail is a common condition of inflammation and infection that can occur when nails are clipped too much or pressure is applied by tight shoes. In Korea, a study on the success of tube insertion after nail guttering has been reported, but studies including other treatments are lacking. Objective: To evaluate the success rates of three treatments for ingrown nails: 1) nail splinting via a flexible tube; 2) partial nail extraction and electrocautery; or 3) partial nail extraction and phenol cauterization. Methods: Fifty-one patients who underwent nail splinting via a flexible tube or partial nail extraction followed by either electrocautery or phenol cauterization of the nail matrix over a 6-year period at our hospital were evaluated for treatment outcome. The disease severity was classified using the Heifetz grading scale. We evaluated the success rates of the various treatments according to reduced disease severity. Treatment failure was defined as persistence or re-occurrence of disease symptoms. Results: 1. Out of 51 cases of ingrown nails, 31 (60%) showed no recurrence after treatment. 2. There were conflicting results between the severity grade and success rate. 3. Treatment via partial nail extraction and either electrocautery or phenol cauterization was more effective (success rates of 63% and 60%, respectively) than nail splinting via a flexible tube (56% success rate). However, the results were not statistically significant. Conclusion: Selecting the proper therapeutic method is important for successful treatment of an ingrown nail.

김영조(Young Jo Kim),이명기(Myung Ki Lee),정병수(Byoung Soo Chung) 대한피부과학회 2001 大韓皮膚科學會誌 Vol.39 No.5

N/A Background: Ingrown nail is a common disorder that occurs most frequently in the great toe and gives affected patients a great discomfort. Many treatments hae been described, such as nail extraction, partial matrix phenolization and wedge excision. However, these treatments modality may lead to damage of the nail and nail fold or to frequent relapses. Objective: We attempted to determine the effectiveness of nail-splinting technique with flexible plastic tube in ingrown nails. Methods: Twenty-nine consecutive patients were treated and enrolled in this study. Without local anesthesia, the lateral edge of the nail plate including the spicule is splinted with a lengthwise -incised small flexible plastic tube, for example, plastic drainage portion of scalp vein set. The plastic tube retained for 2 weeks without any medication. Results: Among the 29 patients, 24 patients were treated successfully without recurrence. After splinting, the patients experienced relief of pain immediately or 1~2 days later, therefore patients are able to lead ordinary lives more qvldrly. Conclusion: Nail-splinting technique with flexible plastic tube in ingrown nails is an effective treatment with relatively low recurrence rate. This method demands little skill and carried out in general practice. It gives an excellent cosmetic result with immediate pain relief, thus fulfilling the main requirements for the primary treatment of choice.

최은미 ( Eun Mee Choi ),정영희 ( Young Hi Jeong ),김기영 ( Ki Young Kim ) 대한미용학회(구 대한미용과학회) 2011 대한미용학회지 Vol.7 No.1

Ingrowing toenail is one of the most common nail complaints. In nail care, the acrylic nail is the method for making artificial nails with hardening of the shape within a certain time after mixing a blend of 3 other materials-polymer methyl methacrylate polymer powder, monomer the liquid acryl and catalyst. The acrylic nail which makes the artificial nails can be used in improvement of ingrown nails. In this study, it was conducted the experiment during 8 weeks that the square type acrylic nail treatment on the big toenail of 12 ingrown nail women without infection. Before the experiment and 2, 4, 6, 8 weeks later of that, the improvement effect of ingrown nail was investigated by measuring the width of C-curve and observation of the change of C-curve shape and question about pain. As a result, the width of C-curve of right big toenail was significantly increased 24.22±6.11% from 11.50±1.23 mm to 14.24±1.24 mm 8 weeks later. And that of left big toenail was increased 21.76±7.33% from 11.57±1.43 mm to 14.01±1.19 mm 8 weeks later. According to the naked eye observation, there was stronger pain at the beginning of experiment than before the starting of that. But 3~4 days later, the participants answered that there was no pain and 2, 4, 6, 8 weeks later, the width of C-curve was increased in measurement. In accordance with these results, it is confirmed that the ingrown nail treatment is valid on pain relief of ingrown nail. Thus, it is suggested that the acrylic nail treatment is worth of being used in the field of nail cosmetology because that is noninvasive method and is possible to adjust pain of ingrowing and to correct the shape of toenail in a brief time.

( Ui Hyeon Jo ),( Ye Eun Kim ),( Hyunsun Park ) 대한피부과학회 2019 대한피부과학회 학술발표대회집 Vol.71 No.2

Background: Pincer nail is the transverse overcurvature of the nail plate. Both conservative and surgical treatments can be used to treat pincer nail. However, there are no reports regarding the non-surgical, laser treatment of pincer nail. Objectives: To evaluate the efficacy and adverse effects of combination of CO₂ fractional laser and topical agent on pincer nail. Methods: Eleven pincer nails (All great toenails) were treated with CO₂ fractional laser. An antifungal agent (in case of co-existing onychomycosis) or 20% urea cream were applied to the toenails. We evaluated the difference of the width index, height index, nail angle, and the level of pain before and after treatment. All adverse events and recurrence were observed until the last follow-up visit. Results: The mean number of laser treatments was 2.27. The mean follow-up period after the last treatment was 18.36 weeks. The width index, height index, and nail angle was significantly changed after the treatment. The width index increased by 0.16 (p-value 0.0016), the height index decreased by 1.89 (p-value 0.008), and the nail angle increased by 29.60° (p-value 0.005). The level of pain was reduced in all cases. There were no serious adverse events. Conclusion: CO₂ fractional laser and topical agent combination therapy can be an effective and tolerable treatment for pincer nail. To confirm this result, larger studies with long-term observation are needed.

Background: Ingrown nail is a common nail disorder frequently resulting pain and disabilities in daily life. It is often difficult to manage despite the multitude oftreatment modalities. K-D wire三 is a recently developed device with shape-memory alloy for treatment of ingrown nail. Objectives: The aim of this study was to evaluate the recurrence rate of K-D wire三 and to determine what factors influence the outcome of the device.Methods: Between June 2010 and July 2015, 86 nails of 62 patients underwent K-D wire insertion in departmentof dermatology of Samsung Medical Center, Seoul. Removal of device and follow up was done for 56 nails. Mean age of affected patients, average stage of ingrown nails, application period of K-D wire, history ofonychomycosis, presence of subungual hyperkeratosis, nail plate width, curvature, center-to-edge angle, and type of ingrown nail was assessed for all nails and compared them between recur group and non-recur group. Results: Recurrence rate was 21.4%. Application period was signifiacant lower in recur group. Other factors were not significantly different from recur to non-recur group. Conclusion: Low recurrence rate was associated with at least 4 weeks of application of K-D wire. Other factors were not associated with recurrence. Since spontaneous dislocation is frequent in K-D wire insertion, developing strategies to reduce early dislocation is important for better efficacy of the device.

Jung, Dong Ju,Kim, Jae Hee,Lee, Hee Young,Kim, Dong Chul,Lee, Se Il,Kim, Tae Yeon Korean Society of Plastic and Reconstructive Surge 2015 Archives of Plastic Surgery Vol.42 No.2

Background Pincer nail deformity is a transverse overcurvature of the nail. This study aimed to define the anatomical characteristics of pincer nail deformity and to evaluate the surgical outcomes. Methods A retrospective review was conducted on 20 cases of pincer nail deformity of the great toe. Thirty subjects without pincer nail deformity or history of trauma of the feet were selected as the control group. Width and height indices were calculated, and interphalangeal angles and base widths of the distal phalanx were measured with radiography. We chose the surgical treatment methods considering perfusion-related factors such as age, diabetes mellitus, kidney disease, and peripheral vascular disease. The zigzag nail bed flap method (n=9) and the inverted T incision method (n=11) were used to repair deformities. The outcomes were evaluated 6 months after surgery. Results The interphalangeal angle was significantly greater in the preoperative patient group ($14.0^{\circ}{\pm}3.6^{\circ}$) than in the control group ($7.9^{\circ}{\pm}3.0^{\circ}$) (P<0.05). The postoperative width and height indices were very close to the measurements in the control group, and most patients were satisfied with the outcomes. Conclusions We believe that the width and height indices are useful for evaluating the deformity and outcomes of surgical treatments. We used two different surgical methods for the two patient groups with respect to the perfusion-related factors and found that the outcomes were all satisfactory. Consequently, we recommend taking into consideration the circulatory condition of the foot when deciding upon the surgical method for pincer nail deformity.
