Background:. Breast cancer is the most common noncutaneous malignancy amongst women. Lumpectomy with adjuvant radiation is a mainstay of surgical treatment. Oncoplastic breast reconstruction reduces the resultant breast deformity. Obesity is a risk factor for the development of complications after breast reconstruction. This study’s purpose was to determine if oncoplastic breast reconstruction is a safe procedure in obese patients. Methods:. A single institution retrospective chart review was performed on women undergoing oncoplastic breast reduction from 2009 to 2021. Patients were then divided into groups based on body mass index (BMI). A statistical analysis was performed comparing rates of complications and time to adjuvant therapy. Results:. An estimated 340 patients were identified with an average age of 56.2 years (140 with BMI 40 kg/m2). There was a significant difference between the BMI greater than 40 kg per m2 and BMI less than 30 kg per m2 group in the number of returns to the operating room (P = 0.0096), major complications (P = 0.0002), and minor complications (P = 0.0051). Average time to adjuvant treatment was 47 days and there was no statistically significant difference between the groups (P = 0.1691). Conclusions:. There was a significant difference in major and minor complications between the BMI groups; however, there was no delay in the time to adjuvant therapy. Therefore, we conclude that with appropriate counseling on surgical risks, oncoplastic breast reduction is an acceptable option for breast cancer patients after lumpectomy, regardless of BMI.

Background:. Microsurgical advances have led to minimally invasive approaches for mandibular reconstruction. Currently, no resource compares all minimally invasive microvascular mandibular reconstruction (MIMMR) treatment options. Methods:. All known cases of MIMMR were identified following the Preferred Reporting Items for Systematic Reviews, Meta-Analyses guidelines, and our own surgical experience. Patient demographics, MIMMR type [submandibular (SM), modified facelift/retroauricular (MFL/RA), or intraoral (IO)], methodology, and clinical outcomes were analyzed with the Fisher exact and Kruskal-Wallis tests. Results:. Forty-seven patients underwent MIMMR. Ameloblastoma was the most common pathology treated using all approaches, and MFL/RA was the only approach used to treat squamous cell carcinoma (P = 0.0103). Reconstruction was reported for large, bilateral defects only via the SM or IO approach (P = 0.0216). The iliac crest or fibula was used as a donor site. The facial artery was the most common recipient vessel using the IO and SM approaches, whereas the superior thyroid and external carotid vessels were the most common in the MFL/RA approach (P < 0.0001). Virtual planning was used in all cases performed via an IO approach, 80.0% of cases using an SM approach, and no MFL/RA cases (P < 0.0001). Good aesthetic and functional outcomes were reported for every patient, and there was no difference in complication rates (P = 0.2880). Conclusions:. Minimally invasive approaches are safe and effective treatment options for patients requiring mandibular microsurgery, usually in the setting of benign pathology. The IO and SM approaches usually rely on the facial vessels, whereas the MFL/RA approach permits access to the superior thyroid and external carotid vessels and cervical lymphadenectomy.
