Reconstruction of finger contracture with an expanded first dorsal metacarpal artery perforator flap: A case report.

Volar finger contractures can be challenging for plastic surgeons. The dorsal metacarpal artery perforator (DMCAP) flap is frequently used to cover bones, tendons, and neurovascular structures in the dorsum of the hand after trauma and burns as an alternative to grafts and free flaps. We aimed to report volar finger defect reconstruction with expanded DMCAP flap. A 9-year-old male patient applied to our clinic with the complaint of inability to open the second finger of the left hand after an electrical burn that caused proximal and distal interphalangeal joints flexion contractures. Reconstruction was planned for the patient with a two-session expanded first DMCAP flap. A 16 mL 5 × 3 cm tissue expander was placed in the prepared area from the vertical incision in the first session. The tissue expander was inflated with 4 mL of isotonic solution. The DMCA area was enlarged 6 weeks later by giving 22 mL of isotonic solution. After the pedicle dissection, the 9 × 3 cm DMCAP flap was elevated by dissection over the paratenon. With 180° of rotation, the left-hand second finger was adapted to the 6 × 2 cm defect area on the volar face. The flap donor site was closed primarily. The operation was terminated by placing the hand on a protective splint. There were no complications in the flap in the postoperative 6 months. The patient was referred to the physical therapy and rehabilitation department. As a result, an expanded DMCAP flap may cover volar tissue defects up to the distal phalanx. This report may present the first case in which volar finger contracture reconstruction was performed with an expanded first DMCAP flap after an electrical burn in a pediatric patient.

Near-total gluteal defect reconstruction with bilateral delayed giant lumbar artery perforator flaps: A case report.

The reconstruction of the near-total or total gluteal defects is challenging. Reconstructive options were restricted when the gluteal flaps were sacrificed. The lumbar artery perforator flap (LAPF) has been recently popularized as an alternative option for sacral and gluteal pressure ulcers. Extension of flap size may be needed in extensive defects. We aim to use the delay phenomenon to increase lumbar artery perforator flap territory to reconstruct near total gluteal defect. A 36-year-old woman was referred to our clinic with defect sizes of 23 × 23 cm and 25 × 17 cm for the right and left gluteal regions. She had a history of multiple surgeries for her paraplegia-related sacrogluteal pressure sores. The reconstruction was started on the left side with delaying incisions to the flap borders. Seven days later, the left gluteal defect was reconstructed with 27 × 19 cm LAPF based on a second lumbar artery perforator. At the same session, the delaying incision was performed to the borders of the right LAPF. On day 14, the right gluteal defect was closed with a 25 × 25 cm-sized right LAPF. No flap loss and early complications were seen. The patient was discharged without complication after 10 days after the last operation. The patient was followed up for 1 year. A right ischial pressure ulcer due to wheelchair use was encountered, which was managed with conservative wound care in the 8th month. Giant-sized lumbar artery perforator flaps may be obtained by delay phenomenon to reconstruct near-total or total gluteal pressure sores.

Novel Scalp Flap Elevation With Balloon Trocar Dissection Device.

BACKGROUND: Balloon trocar devices have been utilized in several surgical cases to reach a difficult-to-access location, achieve hemostasis, and obtain safe, efficient surgery. OBJECTIVE: Highlight the balloon trocar dissection device in a novel technique of scalp flap elevation for tissue expander placement. METHODS: The pocket for the tissue expander was determined at the scalp. A 2 cm vertical incision was made. A 12 mm balloon trocar is then introduced and insufflated. Through the trocar, endoscopic light is then inserted. Scalp flap elevation was performed with the device. The exact location of the pocket was seen with the lumination of endoscopic light. RESULTS: The balloon trocar dissection device provides easy scalp flap elevation and bleeding control. With the help of endoscopic light, the pocket for the expander was created precisely. CONCLUSION: The balloon trocar device is simple, effective, low-cost equipment for tissue expander placement in the scalp.

The effect of hydrochlorothiazide on the recurrence of nonmelanoma skin cancer: a 7-year retrospective study comprising 300 patients.

BACKGROUND: Hydrochlorothiazide (HCTZ) possesses well-described photosensitizing properties, and a causal association with nonmelanoma skin cancer (NMSC) was recently shown. However, previous studies have not shown whether HCTZ use is associated with the risk of recurrence of basal cell carcinoma (BCC) or squamous cell carcinoma (SCC). This study aims to investigate the association between HCTZ use and recurrence in patients with NMSC. METHODS: We identified cases with NMSC from our hospital archives during the period between 2013 and 2019. Patients were divided into groups according to the pathological diagnosis, HCTZ use, and recurrence. Multivariable analysis was performed to determine factors associated with recurrence in BCC and SCC. RESULTS: Recurrences of BCC were significantly higher in HCTZ users with ORs of 4.839221 (95% confidence interval [CI], 1.22-19.12).In HCTZ users, NMSC cases were associated with increased age (p < 0.001 for both BCC and SCC). BCC recurrences were statistically significant with age, longer follow-up, and positive margins after excision in HCTZ users (p = 0.048, 0.020, and, 0.003, respectively). SCC recurrences were not significantly associated with HCTZ use. DISCUSSION: HCTZ use is significantly associated with BCC recurrences. Especially in the elderly population, cases with a positive margin should be followed closely.
