Verruca vulgaris is caused by human papillomavirus (HPV) infections. Verruca in the external auditory canal (EAC) has rarely been reported. A previous case report introduced surgical excision as a treatment for verruca in the EAC. We present a case of verruca vulgaris in both EACs that was successfully treated with an intralesional bleomycin injection. A 32-year-old male patient presented with ear fullness and palpable lumps in both EACs. Both of his canals were filled with multiple pinkish, pap

Background In the extremities of premature infants, the skin and subcutaneous tissue are very pliable due to immaturity and have a greater degree of skin laxity and mobility. Thus,we can expect wounds to heal rapidly by wound contraction. This study investigates wound healing of full-thickness defects in premature infant extremities. Methods The study consisted of 13 premature infants who had a total of 14 cases of fullthickness skin defects of the extremities due to extravasation after total pa

To improve the cosmetic results of removing epidermal cysts, minimally invasive methods have been proposed. We proposed a new minimally invasive method that completely removes a cyst through a small hole made by a CO2 laser. Twenty-five patients with epidermal cysts, which were 0.5 to 1.5 cm in diameter, non-inflamed, and freely movable, were treated. All of the patients were satisfied with the cosmetic results. This method is simple and results in minimal scarring and low recurrence rates witho

Background Intractable chronic scalp ulcers with cranial bone exposure can occur along the incision after cranioplasty, posing challenges for clinicians. They occur as a result of severe scarring, poor blood circulation of the scalp, and focal osteomyelitis. We successfully repaired these scalp ulcers using a vascularized bipedicled pericranial flap after complete debridement. Methods Six patients who underwent cranioplasty had chronic ulcers where the cranial bone, with or without the metal pla

Background Full-thickness skin grafts (FTSGs) are generally considered unreliable for coverage of full-thickness finger defects with bone or tendon exposure, and there are few clinical reports of its use in this context. However, animal studies have shown that an FTSG can survive over an avascular area ranging up to 12 mm in diameter. In our experience, the width of the exposed bones or tendons in full-thickness finger defects is <7 mm. Therefore, we covered the bone- or tendon-exposed defects o

Titanium micro-mesh implants are widely used in orbital wall reconstructions because they have several advantageous characteristics. However, the rough and irregular marginal spurs of the cut edges of the titanium mesh sheet impede the efficacious and minimally traumatic insertion of the implant, because these spurs may catch or hook the orbital soft tissue, skin, or conjunctiva during the insertion procedure. In order to prevent this problem, we developed an easy method of inserting a titanium

Background: Maxillomandibular fixation (MMF) is usually used to treat double mandibularfractures. However, advancements in reduction and fixation techniques mayallow recovery of the premorbid dental arch and occlusion without the use of MMF. Weinvestigated whether anatomical reduction and microplate fixation without MMF couldprovide secure immobilization and correct occlusion in double mandibular fractures. Methods: Thirty-four patients with double mandibular fractures were treated with openredu

Background: The en bloc sliding gluteus maximus myocutaneous flap was introduced to preserve the vasculature, muscular integrity, sensory innervation, and normal gluteal contour with a midline scar in sacrococcygeal pressure ulcer reconstruction. However, its critical disadvantages include incomplete detachment of the origin of the gluteus maximus and central tension of the closed wound due to round ulcer excision. Therefore, we reviewed the surgical anatomy and applied modifications to achieve

Background In the surgical correction of prominent ear, a technique known as percutaneous adjustable closed otoplasty (PACO), which does not involve skin incision, undermining, or cartilage manipulation, has been developed to resolve problems including hematoma, infection, contour deformities, prolonged use of a compressive dressing, and hospitalization. We modified this procedure to make it more practical and accessible and to achieve better results. In this article, we introduce our modificati

Background: Conservative treatment of deep dermal or full-thickness skin defects often results in hypertrophic scars or contractures; thus, compressive therapy has been used after wound closure to prevent or treat scar deformities. However, wound contraction begins in the early proliferative phase and peaks after 2 weeks. We therefore attempted early compression therapy as a means of conservative treatment of deep-skin defects and evaluated its clinical outcomes. Methods: In 21 cases of deep ski

Background: Cultured allogenic keratinocyte (CAK) and epidermal growth factor (EGF) are commonly used biological treatments for partial-thickness burn wounds. A comparative study was conducted on whether the combination therapy of CAK and EGF promotes partial-thickness burn wound healing.Methods: From January 2020 to March 2021, 73 patients who visited the hospital with partial-thickness burns were enrolled in the study. Patients were treated with CAK (Kaloderm) (n=20), EGF (Easyef) (n=17), and

Purpose: Finger immobilization by Kirschner-wire (K-wire) insertion may be used for postoperative stability after release of scar contracture. K=wire insertion through the phalangeal bone requires drilling and can result in joint and/or tendon injury or pain during wire removal. To prevent these problems, we inserted the K-wire through the soft tissue. Methods: Seventy-five fingers of 45 patients who underwent reconstruction of scar contracture of the fingers were immobilized by K-wire. After co

The surgical reconstruction of severe penile contracture complicated by recurrent urethrocutaneous fistula after multiple failed proximal hypospadias repairs poses a significant challenge due to extensive scarring, soft tissue deficiency, and vascular compromise. We report a successful two-stage reconstruction in a 14-year-old patient with this complex presentation. In the first stage, complete contracture release was performed from the normal urethral opening to the glans tip while preserving t

Lymphangioma is a congenital malformed lymphatic tumor that rarely involves the tongue. In our clinic, a 10-year-old female presented with lymphangioma circumscriptum involving the right two-thirds of the tongue. We administered an intralesional combination injection of triamcinolone, bleomycin, and bevacizumab as a treatment. Almost complete remission after combination therapy was achieved without complications such as edema, swallowing difficulties or recurrence. Bevacizumab, an inhibitor of v

A sialocele is a subcutaneous cavity containing saliva, most often caused by facial trauma or iatrogenic complications. In subcondylar fractures, most surgeons are conscious of facial nerve injury; however, they usually pay little attention to the parotid duct injury. We report the case of a 41-year-old man with a sialocele, approximately 5×3 cm in size, which developed 1 week after subcondylar fracture reduction. The sialocele became progressively enlarged despite conservative management. Compu
