ABSTRACT
Background@#Various treatments exist for addressing volume loss in atrophic scars. Although laser therapy has gained traction in treating atrophic scars, it is associated with side effects, such as post-inflammatory hyperpigmentation or erythema. Additionally, not all types of atrophic scars respond optimally to laser therapy, even after multiple sessions. @*Objective@#This study aimed to evaluate the efficacy and safety of punch elevation for atrophic scars that yielded unsatisfactory outcomes after repeated laser treatment sessions. @*Methods@#Seven patients with atrophic scars on their facial area underwent punch elevation, concurrently supplemented by fractional CO2 laser application to the scar margins. Improvement in volume restoration of atrophic scars was assessed via investigator evaluation and 3-dimensional (3D) image analysis. @*Results@#After 1 month, median volume (interquartile range) of depression improved from 4.39 mm3 (2.23∼9.90 mm3 ) to 1.97 mm3 (1.46∼7.50 mm3 ), indicating a statistically significant difference post-punch elevation (p=0.018). No serious adverse events were reported during follow-up. @*Conclusion@#The efficacy of the punch elevation was objectively evaluated. Punch elevation is a safe and effective therapeutic avenue for atrophic scars that exhibit resistance to laser or alternative interventions.
ABSTRACT
The treatment of pathological scars, such as keloids and hypertrophic scars, can be challenging for dermatologists. The first-line treatment is intralesional corticosteroid injection, especially when patients complain of pain or discomfort. Laser treatment can also be used in patients with keloids and hypertrophic scars. However, even after multiple sessions of intralesional corticosteroid injections and laser treatment, desirable outcomes may not be achieved, and recurrence is common. Recent studies on the efficacy of intralesional bleomycin injection (BLMILI) in treating keloids and hypertrophic scars have suggested that a significant improvement is observed after BLMILI. However, there is limited research on the effectiveness of BLMILI for patients who do not respond to other treatments, such as intralesional corticosteroid injection or laser treatment. Here, we report four cases of BLMILI in keloids and hypertrophic scars that were unresponsive to previous intralesional corticosteroid injection and/or laser treatment.
ABSTRACT
Onychogryphosis is a disorder of nail plate growth, which most commonly involves the toenails. It is characterized by opaque, yellow-brown thickening of the nail plate with associated marked convexity and elongation. Treatment for onychogryphosis can be conservative or operative depending on the cause and medical status of the patient. A 30-year-old male presented with onychogryphosis of the right and left toenails. Since the patient had shown recurrence after simple nail avulsion several years ago, the inverted T incision method and fusiform excision of the hypertrophic hyponychium were performed. No recurrence was observed during the 3-year follow-up period. Our results showed that nail avulsion combined with traction osteophyte removal is a suitable surgical method for treating onychogryphosis.
