ObjectiveTo introduce a modified transsection and longitudinal suture in epicanthoplasty and summarize its effectiveness.MethodsThe clinical data of 119 patients underwent epicanthoplasty with modified transsection and longitudinal suture and with a follow-up time over 6 months between February 2014 and December 2016 were retrospectively analyzed. There were 8 males and 111 females with an average age of 22.7 years (range, 18-38 years). The epicanthus was as eyebrow type in 12 cases, as eyelid type in 57 cases, as tarsalis type in 39 cases, and as backward type in 11 cases. The narrow degree of epicanthus included mild (the lacrimal caruncle covered size was less than 1/3) in 42 cases, moderate (the lacrimal caruncle covered size was between 1/3 and 2/3) in 58 cases, and severe (the lacrimal caruncle covered size was over 2/3) in 19 cases. One hundred and thirteen patients were treated by blepharoplasty at the same time. The new canthus was located on the basis of the inner canthus physiological aesthetics. Through a short transverse incision, dislocated orbicularis oculi muscle near medial canthal ligament and the fiber between the medial canthal ligament and skin were completely released; then the medial canthal ligament was shortened precisely and the incision was tension-free sutured followed the Langer’s line near eyes.ResultsAll the incisions healed by first intention. All patients were followed up 6 months to 2 years (mean, 8.6 months). The bilateral hypertrophic scar on both bilateral medial canthal incisions happened in 3 patients at 3-6 months after operation; and the scarring gradually subsided at 10 months after the diprospan injections and the siliconegel and carbon dioxide laser treatment. Good effectiveness were obtained in the other patients, whose inner intercanthal distance significantly narrowed, both of the horizontal lid fissure length increased, the lacrimal caruncle fully exposed, and no obvious scar could be seen.ConclusionThe modified transsection and longitudinal suture in epicanthoplasty has the advantages of simple design, easy operation, minimally invasive, inconspicuous scar, and obvious, stable, and lasting postoperative effectiveness.
Objective To investigate the cl inical directive significance of three-dimensional reconstruction of CT in treating mandibular angle hypertrophy. Methods Between March 2009 and January 2011, 18 patients with mandibular angle hypertrophy were treated using the three-dimensional reconstruction technology of CT. All patients were female, aged20-36 years with an average of 25 years. Eighteen patients included: 14 single mandibular angle hypertrophy, 3 mandibular angle hypertrophy with masseter hypertrophy, and 1 mandibular angle hypertrophy with bilateral asymmetry; 6 cases of ptosis of mandibular angle, 9 cases of prominent mandibular angle, and 3 cases of introversive mandibular angle. According to the types of mandibular angle hypertrophy, the surgical methods could be correctly chosen. The procedure was planned and simulated; the osteotomy l ine was marked and the osteotomy was measured on the workstations of three-dimensional reconstruction. Results No fracture of mandible occurred in the operation. Facial nerve temporary attack occurred in 1 case and recovered at 3 months after operation. All patients were followed up 6-12 months (mean, 7.6 months). After 6 months of operation, the effectiveness was satisfactory in 15 cases, basically satisfactory in 2 cases, and unsatisfactory in 1 case (bilateral asymmetry). Conclusion Based on three-dimensional reconstruction technology of CT, surgical design performed on the model will promote the accuracy of operation. Basically symmetrical appearances can be achieved with satisfactory results.
Objective To introduce the myocutaneous flap in blepharoplasty and summarize its clinical efficacy. Methods Between January 2013 and March 2016, 1 560 patients underwent blepharoplasty with myocutaneous flap. Of them, 158 patients were followed up over 6 months and included in the study. There were 18 males and 140 females with the average age of 23.4 years (range, 18-35 years). The unilateral side was involved in 13 cases and bilateral sides in 145 cases. The patients had narrow double eyelid, shallow double eyelid, single eyelid, bloated upper eyelid, and upper eyelid skin relaxation. During operation, the tissue between the orbicular muscle of eye and the tarsus was trimmed layer by layer; the orbicularis oculi muscle, capillary network, and the front fascia of tarsus were retained, and the full-thickness skin, muscle, and the front fascia of tarsus were sutured by anatomical apposition. Results Incision healed at stage I. All patients were followed up 6 months to 2 years (mean, 8.3 months). During follow-up period, shallow or extinctive double-eyelid line was observed in 9 cases (12 eyes), and satisfactory results were achieved after trimming front fascia of tarsus and suturing. Good clinical results were obtained in the other patients, who had natural and coherent double eyelid without obvious scar or depression at resection margin. Conclusion Myocutaneous flap for blepharoplasty has many advantages of fast recovery, little wound, light swelling, permanent effects, and good appearance.
ObjectiveTo investigate the effectiveness of modified kite flap in repair of soft tissue defect after divided nevus of lateral canthus excision.MethodsBetween October 2010 and April 2018, 20 children (20 eyes) with divided nevus of lateral canthus were admitted. There were 13 boys and 7 girls, with an average age of 7.9 years (mean, 4-14 years). There were 11 cases of moderate range lesions (maximum diameter, 1.5-2.0 cm) and 9 cases of small range lesions (maximum diameter, <1.5 cm). After excising the divided nevus of lateral canthus, the area of soft tissue defect ranged from 0.72 to 3.23 cm2. The modified kite flap was used to reconstruct the structure and shape of lateral canthus.ResultsThere were 16 cases of mixed nevus and 4 cases of intradermal nevus. The flaps survived and the incisions healed by the first intention. The patients were followed up 12-22 months (mean, 13.6 months). There was no malformation, valgus, exposure keratitis, or obvious scar. No malignant transformation occurred or nevus recurred during follow-up. At last follow-up, the effectiveness was rated as excellent in 16 cases, good in 3 cases, and poor in 1 case.ConclusionThe modified kite flap can repair the soft tissue defect after excising the divided nevus of lateral canthus, and obtain the good appearance and function of lateral canthus.
ObjectiveTo explore the effectiveness of modified rhomboid flap for repairing facial skin and soft tissue defect.MethodsBetween January 2016 and May 2018, 23 patients with facial skin and soft defect were repaired by the modified rhomboid flap. There were 10 males and 13 females with the median age of 27 years (range, 11-72 years). The primary tumor included pigmented nevus in 18 cases, basal cell carcinoma in 4 cases, and squamous cell carcinoma in 1 case. The defect location was nose in 8 cases, cheek in 4 cases, malar in 6 cases, forehead in 2 cases, and upper lip in 3 cases. The defect ranged from 0.8 cm×0.8 cm to 3.9 cm×3.9 cm. According to the location and size of facial tumors, the resection area of square lesions was designed. According to the mobility of surrounding tissues and the direction of dermatoglyphic lines, the rhomboid flaps with an angle of 45–60° was designed to repair the defect by tension-free rotation.ResultsAll the flaps survived and the incision healed by first intension. All patients were followed up 3-15 months (mean, 7.3 months). During follow-up, no tumor reoccurred; the color and texture of the flaps were similar with surrounding tissue. There was no obvious scar hyperplasia, nor traction of adjacent normal tissues, and patients were satisfied with the appearance.ConclusionThe application of modified rhomboid flaps in repairing facial skin and soft tissue defects caused by resection of round facial tumor has the advantages of flexible design, simple manipulation, and less trauma.
