The described technique is simple, safe, and reliable, providing sustained results over the long-term follow-up period with a high rate of stable eversion and patient satisfaction.

Neurofibromatosis(NF) is an autosomal dominant systemic disease. Up to 50% of patients with NF are reported to have concomitant vascular abnormalities. In the resection of a larger NF, the risk of uncontrolled hemorrhage is much higher due to the difficulty of hemostasis of large vessels within the tumor. We ligated the base of the giant NF with a simple loop-shaped ligation before removal of the giant NF in both buttocks, following this, we could successfully reduce the amount of hemorrhage during the operation. A 46-yearold female patient presented with giant masses of both gluteal areas, which had been growing slowly for the last 10 years. Each mass was about 35×25 cm in size. After designing the elliptical resection margin, we tightened the tumor base by using continuous loop-shaped suture ligation (weaving the thread up and down in a loop-shaped pattern, leaving a space of 2 cm between each loop) a straight needle and prolene 2-0 was used after skin incision. We proceeded with the dissection towards the central and inferior side of the mass obliquely while we avoided opening large vascular sinuses. We resected the tumor in a wedge shape. Subcutaneous tissue was sutured layer by layer, and skin was closed by vertical mattress and interrupted sutures. The loop-shaped ligation of the base was removed, and compressive dressing was done with gauze and elastic bandages. Postoperative complications such as infection, hemorrhage, hematoma, and dehiscence did not occur. Perioperatively, the patient was sufficiently transfused with only two units of blood. During the subsequent 1 year followup, the functional and cosmetic results were excellent. A continuous loop-shaped suture ligation procedure along the base of the giant NF effectively reduced the amount of hemorrhage during the operation, made dissection and ligation of vessels easy and quick, shortened the operating time and postoperative recovery time.

Purpose: This study aims to evaluate the efficacy of frontalis muscle flap suspension in treating moderate to severe blepharoptosis. Study subjects: 54 eyes of 47 moderate to severe blepharoptosis patients (aged 17.34 ± 9.17 years, 18 males, 29 females). Study design: Prospective uncontrolled clinical trial. Results: Following frontalis muscle flap suspension surgery, there was a statistically significant improvement (p<0.001) in margin reflex distance 1 (MRD1) and palpebral fissure height (PFH), from 0.009 ± 0.60 mm and 5.59 ± 0.68 mm (pre-operation) to 2.68 ± 1.10 mm and 8.26 ± 1.14 mm (1 week after operation), 3.63 ± 0.77 mm and 9.24 ± 0.85 mm (6 months after operation), 3.45 ± 0.80 mm and 9.02 ± 0.89 mm (12 months after operation). At the 12th month after operation, it was found that severe lagophthalmos, lid lag on down-gaze and forehead hypoesthesia were present in 7.4%, 9.3% and 14.0% of all treated eyes, respectively. Excellent functional results were determined in 66,0% of procedures postoperatively, with 31,9% and 2,1% rated as good and unsatisfactory. In terms of cosmetic results, 78,7%, 19,1% and 2,1% of cases were rated as excellent, good and unsatisfactory, respectively. Conclusion: Majority of case results were excellent (78,7%) and good (19,1%), unsatisfactory cases 2,1%.

Objectives: Describe anatomical characteristics of the temporal branch of the facial nerve within the parotid gland in Vietnamese adults. Study population: The study was conducted in 12 hemifaces (right: 7; left: 5) of Vietnamese adult cadavers (5 cadavers with both hemifaces and 2 cadavers with only hemiface). Gender: 4 male (57.1%) and 3 female (42.9%). The average age was 73.0 ± 13.39 years (52-88 years). Method: Descriptive cross-sectional with analysis. Result and Conclusion: Most of the temporofacial trunks were located within the parotid gland (81.8%); 18.2% were located behind the parotid gland. The length of the facial nerve within the parotid gland was 8.88 ± 3.55 mm (4.62 - 16.96mm). The distance from the division point of the temporofacial trunk into the temporofrontal branch and the orbital nerve branch to the line (d) [crossing through the lateral canthus (A) and the point that root of the helix intersecting with the face] and (d2) [crossing the lateral canthus and the upper point of the tragus, just above the upper edge of external auditory canal] was 36.06 ± 7.50mm (19.26- 45.34 mm) và 21.94 ± 6.28 mm (11.52- 37.20 mm).
