Acellular dermis-assisted breast reconstruction with the use of crescentric tissue expansion: a functional cosmetic analysis of 40 consecutive patients.
BACKGROUND
Crescentric tissue expanders have the potential to improve postoperative aesthetic results via selective lower pole expansion; however, limited data are available on their efficacy.


OBJECTIVE
The authors assess postoperative functional and cosmetic outcomes of acellular dermis-assisted breast reconstruction with crescentric tissue expansion.


METHODS
This study is a single-institution, retrospective review of 40 consecutive patients who underwent acellular dermis-assisted breast reconstruction with crescentric tissue expansion. Demographic data, operative details, and procedural outcomes were recorded and assessed. Cosmetic outcomes were assessed using the Breast Evaluation Questionnaire.


RESULTS
Fifty-eight breasts representing 36 bilateral and 22 unilateral reconstructions were analyzed. Of these, 45 (78%) underwent tissue expander (TE) to implant exchange. The mean interval between stage 1 and stage 2 was 92 +/- 20 days, with a total follow-up time of 141 +/- 16 days. The average intraoperative expander fill volume was 213.5 mL, with an average final fill of 285 mL (range, 180-740 mL). The average number of expansions was 1.6. Overall, there were five complications (8.6%). Eighty-three percent of patients participated in the breast evaluation questionnaire. Answers to each question were reported using a qualitative five-point scale that ranged from 1 (very dissatisfied) to 5 (very satisfied). For the bilateral reconstructions, the average score in all contexts was 4.5 +/- 0.3, 4.33 +/- 0.5, and 4.36 +/- 0.33 for size, shape, and firmness, respectively. For unilateral reconstructions, the average scores were 4.0 +/- 0.58, 3.93 +/- 0.38, and 4.13 +/- 0.21, respectively.


CONCLUSIONS
Crescentric expander-based reconstruction with acellular dermis assistance is well tolerated, especially in smaller breasted women. Functional and cosmetic outcomes were acceptable and comparable to previous reports of traditional expander-based reconstructions.
