Abstract:
Objective:To investigate the functional recovery and cosmetic effects of pre-expanded pedicled deltopectoral flap.
Methods:From January 2008 to December 2018, 42 patients with 56 pre-expanded pedicled deltopectoral flaps from Xijing Hospital of Air Force Military Medical University were followed up at least 6 months. 18 of them were male, the remaining were female. And the average age was (24.7±7.3) years. Then the indicators were tested and evaluated. Tubes with different temperatures were used for temperature sensation test. The flaps were stabbed using a 27 G blunt needle to test algesthesia. Tactile threshold was measured by Semmes-Weinstein monofilament. Two-point discrimination was measured by Disk-Criminator. Elasticity of skin flaps was measured by CK-MC®960. Colors of skin flaps were analyzed by ANTERA®3D system, including L*a*b*, melanin and hemoglobin content. And the postoperative scars were evaluated by the Patient and Observer Scar Assessment Scale (POSAS). The flap retraction rate [(flap area immediately after operation-flap area at the follow-up time)/flap area immediately after operation]was calculated. The satisfaction of patients, doctors and third parties was investigated as well. Statistical analysis of data was performed with SPSS 23.0, satisfaction rate was expressed as percentages. Scar scores were compared by Wilcoxon rank sum test. The values of elasticity, color L*a*b*, melanin and hemoglobin between skin flaps and normal skin were analyzed by paired t test. The difference was statistically significant at P<0.05.
Results:The scores of pain, heat and cold sensation were (4.61±0.78), (3.48±0.90) and (4.39±0.81), the tactile threshold was (0.26±0.23) g/mm2, and the distance of two-point discrimination was (10.09±4.79) mm. There was no significant difference in elasticity, color b*and melanin content between skin flap and normal skin of face and neck (P>0.05). The color of flap L*, a*and hemoglobin content of flaps were significantly different from those of normal skin from face and neck (P<0.05). The result of self-assessment of patients (POSAS) showed that there were significant differences (P<0.05) in pain, itch and stiffness between facial and chest donor scar. The result of observer evaluation (POSAS) showed that the scar score for all items around facial flap was better than that of chest donor area, the difference was statistically significant (P<0.05), and the retraction rate of flaps was (10.44 ±3.36)%. The satisfaction rates of doctors, patients and the third party were 92.86% (39/42), 71.43% (30/42) and 61.90% (26/42), respectively.
Conclusions:Excellent functional recovery and reliable cosmetic effect were observed in the facial-cervical scar repair with pre-expanded pedicled deltopectoral flap. Transfer of pre-expanded pedicled deltopectoral flap is an effective method for the treatment of facial-cervical scars.
