ABSTRACT
The use of dermal substitutes is considered an effective treatment in several pathologies involving skin damage, mainly extensive burns and trauma. Treatment alternatives entail performing flaps or autografts. The purpose of this cross-sectional study is to assess the clinical effects and cost-effectiveness of dermal substitutes in surgical procedure in complex wound healings of adult trauma patients. The study includes 52 patients who received dermal substitutes (n = 25) between 2007 and 2012 and patients treated between 2006 and 2011 who received standard treatment (n = 27). All patients presented with posttraumatic soft tissue defects with bone and/or tendon exposure. Differences in costs, mean differences in Euros and Euros per square centimeter, and clinical data were collected as outcome measures. Pearson's correlations were used to assess the relationship between total costs with sociodemographic data and clinical services to different healthcare providers (clinical data and costs were recorded for both groups). No relevant differences on acceptance rates were noticed amongst groups. Surgery costs were shown to be significantly reduced in the dermal substitutes group (P < 0.01) even though total costs (surgery + hospitalization) did not exhibit a significant difference. Surgical time was significantly reduced in the dermal substitutes group (1.81 min/cm(2) lesions) as compared with the standard group (6.08 min/cm(2) lesions). The current study suggests that not only clinical but also possible economic and logistical advantages in choosing dermal substitutes may exist.
ABSTRACT
Facial nerve reconstruction for lesions with nerve gaps frequently require autologous or tubulized grafts of biological or synthetic origin. Neurotube, a bioabsorbable polyglycolic acid tube, represents a valid solution for this kind of defect in emergency and planned surgery. Seven posttraumatic lesions of terminal branches of the facial nerve were repaired by means of Neurotube from September 1999-September 2001. The nerve gap size ranged between 1-3 cm. Nerve regeneration was evaluated at 7-12 months of follow-up when muscle recovery function was examined. Muscle function was very good in 1 case, good in 4, and fair in 2 (71% positive results). No intolerance or discomfort was reported or observed. Neurotube is useful for the reconstruction of facial nerve lesions with a small nerve gap (less then 3 cm) when a direct anastomosis of the two stumps is not possible, or when the suture appears to be in tension. It is a valid alternative to autologous and biological tubulized grafts. The limits of this method are: 1) it can only be used with gaps of less than 3 cm; 2) it is quite costly; 3) there are reports of possible intolerance; and 4) it is not suitable for lesions of the proximal part of the facial nerve.
