Bipolar or monopolar electrosurgery in blepharoplasty: A comparison of surgical outcomes and patient satisfaction.

BACKGROUND: An electrosurgery unit (ESU) is the mainstay of bleeding control in blepharoplasty. There are two different types of ESUs: monopolar (m-ESU) and bipolar (b-ESU). AIMS: We used m- and b-ESUs in upper, lower, and combined blepharoplasty and compared their outcomes. PATIENTS/METHODS: In this retrospective file review of 292 blepharoplasty patients, we excluded 14 who were lost to follow-up or had missing data; among the 278 enrolled patients, we recorded operative time, a surgeon panel's score for edema and ecchymosis on the third postoperative day, patients' scores of their satisfaction and inconvenience, and postoperative complications. RESULTS: One hundred thirty-nine patients were included in the m-ESU and b-ESU group. Overall, 105 patients underwent upper blepharoplasty, 77 underwent lower blepharoplasty, and 96 underwent combined blepharoplasty. The total mean operative time in the m-ESU and b-ESU was 67.94 and 62.82 minutes, respectively. This difference was not significant (P > .05). The panel's edema and patient satisfaction and inconvenience scores were significantly better in the b-ESU group (P < .05). There were no significant differences in the panel's ecchymosis score and frequency as well as nature of complications between the m-ESU and b-ESU group (P > .05). CONCLUSIONS: In this cohort of blepharoplasty patients, minimally invasive b-ESUs were efficient in obtaining reliable surgical results with higher satisfaction and lower inconvenience rates of patients than m-ESUs. We would like to recommend the use of b-ESUs in blepharoplasty, especially for plastic surgeons inexperienced in periorbital esthetic surgery.

Percutaneous Autologous Fat Injection Following 2-Layer Flap Lower Blepharoplasty for the Correction of Tear Trough Deformity.

Tear trough deformity has been an area that has received much attention in terms of esthetic improvements. Fat transposition has been commonly used for the treatment of tear trough deformity. As some patients have had minimal improvement by that method, we propose the use of fat grafting combined with open blepharoplasty to complement the sunken area, including some of anterior maxilla region, and evaluate and precisely remove the excessive tissue.Lower blepharoplasty was performed by separating the skin and muscle flap. The excessive or laxed tissue was evaluated during the procedure and resected in each flap. Fat grafting was performed after completing a lower blepharoplasty, to ensure accurate placement on the spot where the surgeon originally intended. Overcorrection is not recommended.No serious complications were reported during a period of 10 years. Only 4 patients required a secondary fat injection.Patients who require structural correction of the lower eyelid area (eg, aggressive herniated fat, excessive skin laxity, or bulky orbicularis oculi muscle) and who need complementary material to fill the lower lid area (eg, deep, wide sunken area or relative exophthalmos) are good candidates for blepharoplasty with a fat grafting procedure.

Living donor kidneys: usefulness of multi-detector row CT for comprehensive evaluation.

PURPOSE: To evaluate in living renal donors the usefulness of multi-detector row computed tomography (CT) in the assessment of renal vasculature and the upper urinary tract. MATERIALS AND METHODS: Four-channel multi-detector row CT scans were obtained in 77 patients. Vascular phase scans were used for CT angiography; excretory phase scans, for CT urography. At CT angiography, two independent observers evaluated the number of arteries and veins and the presence of early-branching arteries. CT urographic images were evaluated with regard to the opacification of the urinary tract and for abnormalities. Findings of CT angiography and urography were compared with surgical findings. Interobserver agreement between CT angiographic and surgical findings was quantified with weighted kappa statistics. Sensitivity and specificity of CT angiography in identifying supernumerary vessels and early-branching arteries were also evaluated. To evaluate the radiation dose to patients, weighted CT dose index (DI) was assessed for each scan. RESULTS: Agreement between CT angiographic and surgical findings was excellent for the number of renal arteries (kappa = 0.896) and veins (kappa = 0.843). Detection rate of CT angiography was 98% (89 of 91) for arteries and 98% (83 of 85) for veins. The respective sensitivity and specificity of CT angiography were 86% (12 of 14) and 100% (65 of 65) for supernumerary arteries, 100% (11 of 11) and 100% (66 of 66) for early-branching arteries, and 75% (six of eight) and 100% (69 of 69) for supernumerary veins. At CT urography, collecting systems and proximal ureters were well opacified in all patients; two patients had underrotated kidneys without obstruction. The weighted CT DI was 10.19 mGy for unenhanced and excretory phase scans and 12.88 mGy for the vascular phase scan. CONCLUSION: Multi-detector row CT can help assess well the renal vasculature and the urinary tract of living renal donors.
