Scarless Donor Site for Breast Reconstruction by Endoscopy-assisted Extended Latissimus Dorsi Flap plus Lipofilling.

BACKGROUND: Breast reconstruction using endoscopy-assisted latissimus dorsi (LD) flap leaves no scar on the back; however, the small amount of tissue obtained makes this procedure less practical. This study aimed to propose a new technique of endoscopy-assisted extended LD (eeLD) flap plus lipofilling, which could secure a large breast volume. METHODS: Lateral thoracic adipose tissues supplied by the thoracodorsal artery branches and the LD muscle were elevated as a single unit only through the mastectomy scar and three ports through the lateral chest. Further, fat was simultaneously injected to support the volume and shape of the breast. Changes in the volume of the reconstructed breast over time were measured using three-dimensional stereophotogrammetry. RESULTS: Overall, 15 breasts of 14 patients who underwent breast reconstruction using an eeLD flap exhibited no serious complications. On average, 281.9 ± 32.4 g of flap and 74.7 ± 19.4 ml of lipofilling were used. Within 8 weeks after the procedure, the volume of the reconstructed breast decreased to 69.5% ± 7.5% and then plateaued. Seven patients needed a subsequent session of lipofilling to acquire adequate breast volume and projection. Notably, according to the BREAST-Q back scores, patients who underwent eeLD flap were significantly more satisfied than those who underwent conventional LD musculocutaneous flap using a skin paddle on the back at the same institution (82.8 ± 9.2 vs. 62.6 ± 6.3, P < 0.0001). CONCLUSION: Despite the limitations in volume, eeLD flap plus lipofilling is advantageous because it does not leave a noticeable donor site scar.

Staged Treatment of Asymmetrical Age-related Changes in the Eyelid and Thyroid Eye Disease.

Blepharoplasty for thyroid eye disease (TED) has been indicated for the purpose of improving upper and lower eyelid retraction caused by exophthalmos. Both aponeurotic blepharoptosis and aging lower eyelid are common conditions that require plastic surgeries and could be complicated with other disease conditions, such as TED. This is the first report of planned and staged treatment of the contradictory pathophysiologies of aging changes of upper and lower eyelids associated with TED. A 59-year-old woman suffered complicated bilateral asymmetric aponeurosis blepharoptosis of the lower and upper eyelids, caused by both advanced aging and TED. To achieve aesthetic improvement, three-stage surgical treatments were planned, as follows: (1) Orbital decompression for exophthalmos; (2) Extraocular muscle surgery, if necessary; (3) Blepharoplasty for functional and aesthetic abnormalities due to loosening of the upper and lower eyelids. After medial and lateral orbital floors were opened bilaterally, the patient did not need extraocular surgery. As the final step, levator aponeurosis advancement procedure was performed in the upper eyelids for bilateral asymmetrical aponeurotic blepharoptosis, and transitional lower blepharoplasty using a skin-muscle flap technique via a sub-ciliary incision was performed in the lower eyelids for age-related loosening. The typical face displayed by Graves' disease disappeared, and the symptoms associated with loosening of the upper and lower eyelids improved substantially. Improvement of exophthalmos by orbital decompression revealed the severity of the blepharoptosis and the aging change of lower eyelid. Step-by-step planning from decompression surgery to upper and lower blepharoplasty could lead to sufficient improvement in the facial appearance in TED.

Prevention of venous reflux with full utilization of venoplasty in lymphaticovenular anastomosis.

BACKGROUND: Intraoperative retrograde blood flow from the vein to the lymphatic vessels in lymphaticovenular anastomosis (LVA) for lower extremity lymphedema (LEL) leads to poor results. This study aimed to establish a treatment strategy to control venous reflux in LVA. METHODS: A unified strategy to prevent venous reflux was used in 95 limbs (study group). Dilated perforating veins were ligated, and LVA at the small branch of the ligated vein was considered. External valvuloplasty in the small vein was performed to eliminate venous reflux pre- and post-LVA. A Y-shaped venoplasty for the relatively large vein was considered in cases without adequate-sized vein stump with a functional valve. The results were compared with the 34 limbs undergoing conventional multiple LVAs (control group). RESULTS: Intraoperative venous reflux and postoperative ecchymosis significantly decreased in the study group (0/462 anastomosis vs. 15/148 anastomosis, p < 0.0001 and 0/81 patients vs. 3/25 patients, p = 0.01, respectively). The average frequency of cellulitis during a year following LVA was significantly smaller in the study group than in the control group (0.05 ±â€¯0.03 vs 0.20 ±â€¯0.06, p = 0.04).The amount of improvement in the LEL index a year after LVA was significantly larger in the study group than in the control group (22.2 ±â€¯9.6 vs. 18.3 ±â€¯9.8, p = 0.04). CONCLUSION: Using the new strategy developed in this study, venous reflux could be completely prevented, and stable clinical results were obtained in patients with LEL. Prevention of venous reflux with full utilization of venoplasty might improve the LVA result.
