Unilateral autologous breast reconstruction with unipedicled and bipedicled deep inferior epigastric artery perforator flap: A review of 168 cases over 3 years.

BACKGROUND: Harvesting a DIEP flap based on bipedicled perforators can enhance vascular perfusion, which can reduce complication rates, minimize fat necrosis, and flap failure. This study summarizes our experience with using unipedicled and bipedicled DIEP flaps for breast reconstruction. PATIENTS AND METHODS: A total of 168 consecutive patients undergoing unilateral breast reconstruction with DIEP flaps over a 3-year period were retrospectively reviewed. Primary microvascular anastomoses were performed to the thoracodorsal vessels in both unipedicled and bipedicled DIEP groups. In bipedicled DIEP flap cases, additional secondary microvascular anastomoses were performed either by extraflap or intraflap options. Clinical characteristics and outcomes were recorded. RESULTS: Unipedicled (n = 89; 53%) and bipedicled flaps were used. Both groups were comparable for mean age, diabetes mellitus, hypertension, smoking, and chemotherapy. BMI was 24.9 ± 3.6 in the unipedicled group and 22.8 ± 2.9 in the bipedicled group (p < .001). The surgical duration was longer in bipedicled group (367 ± 86.5 minu vs 403.7 ± 65.6 min, p < .05) but incidence of fat necrosis decreased in the bipedicle group (24 patients [27%] vs. 7 patients [8.9%] p < .05). There was no flap loss or instance of abdominal hernia in any group. CONCLUSIONS: The bipedicled DIEP flaps may be a feasible option for large breast reconstruction in thin patients. However, the additional microsurgical technical complexity and longer operative time must be considered.

Parallel-excision infrabrow blepharoplasty with extensive excision of the orbicularis oculi muscle in an Asian population.

BACKGROUND: Infrabrow blepharoplasty has become a common surgical method used to rejuvenate aged upper eyelids in Asians. In this paper, we describe the parallel excision method for infrabrow blepharoplasty as a useful alternative to the conventional elliptical excision method. The authors' experience over a 3-year period is presented and reviewed. METHODS: A retrospective review of parallel excision infrabrow blepharoplasty cases at our hospital between 2014 and 2017 was performed. Three oculoplastic surgeons compared preoperative and postoperative photographs using the Strasser grading system. RESULTS: From the medical records of 123 patients, a total of 93 patients with moderate-to-severe bilateral dermatochalasis were selected as subjects. The exclusion criterion was levator function less than 8 mm. The total mean follow-up period was 2 years (range, 0.5-3.5 years). The mean skin excision height and width were 9.75 mm (range, 5-16 mm) and 58.51 mm (range, 42-75 mm), respectively. All patients who underwent surgery recovered without major complications, and all patients had high levels of satisfaction and improvements in their visual field. In the Strasser evaluation performed by the oculoplastic surgeons, most patients were found to have excellent results. CONCLUSIONS: The parallel excision method for infrabrow blepharoplasty is a safe and effective technique that yields more natural- and youthful-looking eyelids than the conventional elliptical excision method. In our method, more effective manipulation of the orbicularis oculi muscle led to a reduction in frontalis compensation, resolution of sunken eyelids, and correction of lateral hooding.
