RESUMO
BACKGROUND: There are many situations in integument surgery in which secondary intention healing (SIH) may bring results comparable or even superior to those obtained with primary intention healing. OBJECTIVE: To present our own methods of employing SIH in surgical treatment of different skin lesions. Moreover, to delineate the extended indications for SIH as a first-line method of wound treatment. METHODS: Between 1999 and 2009, we conducted 236 operations followed by SIH in the group of 195 patients. Two independent investigators and the patients carried out post-operative assessment (at 12 months) of both cosmetic and functional results of operations (data for 142 patients). Moreover, at 3 and 12 months, patients were asked for self-evaluation of the outcomes of surgical procedures using the visual analogue scale (VAS). RESULTS: The most frequent indications for SIH were defects after the excision of non-melanoma skin cancers and hidradenitis suppurativa lesions. Depending on localization, the mean extent of the post-operative wounds prepared for SIH ranged from 0.8to 85.7 cm(2). The healing lasted 2-12 weeks. The most important factor was the size of the wound (r = 0.59; P < 0.001). The assessment at 12 months revealed that cosmetic/functional outcomes were evaluated as 'good' or 'excellent' in 89/83% and 72/70% cases, according to patients and physicians respectively. VAS showed that evaluation scores at 3 months post-surgery were significantly lower than at 12 months (P < 0.0001). CONCLUSION: SIH is a safe and efficient form of treatment for various post-operative skin defects. In certain areas of the body, SIH shows favourable cosmetic and functional effects. In these cases, it may even be regarded as the method of choice.
