Objective:To investigate the efficacy of blepharoplasty using the "double-line technique" in addressing upper eyelid skin laxity in middle-aged and elderly patients.Methods:A retrospective analysis was conducted on the clinical data of middle-aged and elderly patients with moderate to severe upper eyelid skin laxity who were admitted to the Plastic Surgery Department of Shaanxi Provincial People’s Hospital between January 2020 and January 2023. The same surgeon performed the "double-line" blepharoplasty to excise excess upper eyelid skin for laxity correction. Patients were positioned flat with their eyes closed; an arcuate line a (5-7 mm above the pupil) and a second line b (aligned with the eyelid margin in an upright position) were marked. The skin between these two lines was excised. Postoperatively, the double eyelid shape, improvement in skin laxity, adverse reactions, and patient satisfaction (categorized as satisfied, basically satisfied, unsatisfied) were assessed.Results:A total of 145 patients were included in the study, comprising 27 males and 118 females. Their ages ranged from 38 to 78 years, with an average age of 52 years. All patients’ incisions healed primarily without complications such as hematoma and infection. During the 3 to 12 months of follow-up after surgery, the double eyelid arcs on both sides appeared symmetrical and natural. The upper eyelid laxity was effectively corrected, obscured vision was improved, crow’s feet were reduced, and the periorbital area was rejuvenated. Patient satisfaction with the surgical results was high, with 112 patients reporting satisfaction, 25 reporting basically satisfied, and 8 reporting dissatisfaction. The overall satisfaction rate reached 94.48%(137/145). Among those dissatisfied, 6 cases cited the double eyelid crease as being too narrow, and 2 cases noted asymmetry in the double eyelid crease.Conclusion:The "double-line method" for blepharoplasty is straightforward to perform and effectively removes excess upper eyelid skin. It is suitable for middle-aged and elderly patients with moderate to severe upper eyelid skin laxity, resulting in favorable surgical outcomes.

Objective:To analyze the clinical effect of small incision approach conjoint fascial sheath (CFS) suspension in the treatment of congenital severe blepharoptosis, and to discuss its advantages and disadvantages compared with conventional CSF suspension.Methods:From February 2020 to August 2022, 42 cases of severe blepharoptosis in the Department of Burn, Plastic and Cosmetic Surgery, Shaanxi Provincial People's Hospital were divided into the observation group (23 cases, 39 eyes) and the control group (19 cases, 37 eyes). The observation group was treated with small incision CFS suspension surgery, while the control group was treated with conventional CFS suspension surgery. The correction effect, complications, recovery time and other conditions between the two groups at different times after surgery were compared.Results:During postoperative follow-up at 1 week, 1 month, 3 months, and 6 months, there was no significant difference in the corrective effect between the two surgical methods at each time point (all P>0.05). The incidence of complications in the observation group at each time point that was 26.3%, 15.7%, 10.5%, and 5.2%, respectively, while the incidence of complications in the control group was 60.0%, 20.0%, 14.2%, and 8.6%, with statistical differences in the first week after surgery (χ 2=8.74, P=0.011). The average postoperative swelling time in the observation group was 4.2 days, which was less than 5.8 days in the control group. During a 6-month follow-up, it was found that there was a decrease in scar hyperplasia in the observation group of 9.1% (2/22) compared to the control group of 16.7% (3/18) (χ 2=0.023, P=0.878). The difference was of no statistical significance. Conclusions:CFS suspension with small incision in the treatment of moderate and severe blepharoptosis has the advantages of ideal correction effect, small damage range, and few postoperative complications, but the operation area is small, the operation is difficult, and the surgeon has higher requirements.

Objective To study the absorption mechanism of free bone autograft and compare the advantages of the membranous and endocbondral bone autografts in rabbits. Methods Thirty adult male New Zealand white rabbits were randomly divided into two groups of fifteen each. Cranium graft or rib graft was implanted on each side of the snouts of the animal. The onlay grafts were harvested at 12th and 24th week. Then gross observation, volume measurement, histological study and scanning electron microscopical observation were performed.Results Cranium graft underwent less resorption than rib graft and the cortical bone underwent more resorption than cancellous bone. The number and arrangement of collagen fibrils at 24 weeks was more and better than that of 12 weeks. The collagen fibrils of the cranium graft were more numerous and regular than those of the rib graft at 12 weeks, but they were similar at 24 weeks. Although the grafts survived, their volume continued to decrease due to stress. Conclusions Membranous bone implanted on cranium of the rabbit is better than endochondral bone. Remodeling time of a cranium graft is shorter than a rib graft. The graft volume is also relating to stress.

ObjectiveTo study absorbed mechanism of free bone auto-graft in cranium.MethodsTwenty-four adult New Zealand rabbits were randomly divided into two groups of twelve each. Cranium graft or rib graft was implanted on each side of the cranium. The onlay graft was harvested at the 12th and 24th week, and the collagen fibers were scrutinized under scanning electron microscope. ResultsThe number of the bone collagen fibrils at twenty- fourth week was more than that of the twelfth week, the arrangement of collagen fibrils at the twenty- fourth week was more regular than that of the twelfth week, and the collagen fibrils of the cranium graft were more numberous and regular than those of the rib graft observed at the twelfth week, but they were similar at twenty - fourth week. ConclusionRemoding time of cranium graft is shorter than that of rib graft, but bone remoding of both cranium and rib has finished in 24th week after operated.
