Reduced Anterolateral Thigh Flap Donor-Site Morbidity Using Incisional Negative Pressure Therapy.

BACKGROUND: Primary closure of the donor-site after harvest of a large anterolateral thigh flap (ALT) is associated with significant morbidity. Incisional negative pressure therapy (INPT) may decrease complications in high-risk incisions. This study assessed if the incidence of complications after primary closure of the ALT flap donor-site decreases with INPT. METHODS: Retrospective cohort study of a prospectively maintained database including patients who underwent upper and lower limb reconstruction, using an ALT free flap with primary closure of the donor-site. Two groups were defined: primary closure and INPT (study group) and primary closure with traditional dressings (control group). Nonparametric statistics were employed to identify prognostic factors, p < 0,05. RESULTS: Fifty-eight free ALT flaps in 58 patients (study group n = 28; control group n = 30) were included. Median flap width and length were 9 cm (range: 5-14) and 25 cm (range: 10-48), respectively. Median follow-up was 19 months (range: 3-78 months). No significant differences in age or flap size were identified in both groups (p > 0.05). The global complication rate was 7.14% (n = 2) in the INPT group, and 37% (n = 11) in the control group (p = 0.007). The study group had a lower dehiscence and skin necrosis rate (p < 0.05). Multivariate logistic regression analysis showed IPNT was associated with a significant reduction of donor-site complications (p = 0.006), especially in patients with defects > 8 cm (p = 0.003). CONCLUSION: In this cohort study the use of INPT significantly reduced the donor-site morbidity after ALT flap harvest.

Infecciones profundas del cuello / Deep neck infections

Deep neck infections (DNIs) are special entities among infectious diseases for their versatility and potential for severe complications. Complex head and neck anatomy often makes early recognition of DNIs challenging, and a high index of suspicion is necessary to avoid any delay in treatment. The diagnosis is made by clinical history, physical examination findings and imaging studies. The treatment consists in securing the airway, intravenous antibiotics and surgical drainage, when needed. To make decisions the surgeon must understand the anatomy of the region, the etiology of infection, appropriate diagnostic tools, and medical and surgical management. This article provides a review of these pertinent topics. (AU)
