Background: Sunken upper eyelid makes people's eyes look gaunt and aging. At present, more and more people are paying attention to eye rejuvenation, and more and more people are asking for correction of sunken upper eyelid. Orbital septum fat plays an important role in the display of eye contour. Therefore, the position of orbital septum fat can be adjusted surgically to improve the upper eyelid depression.Objective: This article discusses the clinical effect of orbital septum fat flap transfer in the upper eyelid depression of mild to moderate. Methods: Thirty patients with single eyelid depression in our hospital from April to September 2020 were selected. After blepharoplasty, the orbital septum fat was fully released and the lateral orbital fat transfer was fixed to the mid-medial upper eyelid depression. Results: After the operation, 29 patients were satisfied with the results, with good incision healing, bilateral basic symmetry no obvious scar, and negative effect of non-convex and concave eyelid inequality. One patient did not achieve the expected results and was treated with a second autologous fat filling. Conclusions: For patients with mild to moderate sunken upper eyelid, orbital septal fat flap metastasis during blepharoplasty has not only good effect, natural appearance, and smooth upper eyelid skin, but also only 1 incision for upper eyelid formation, which has high acceptance and satisfaction of patients and can be widely used in clinical practice.

Some basic properties in Orlicz spaces and Orlicz sequence spaces that are generated by monotone function equipped with the Mazur-Orlicz F-norm are studied in this paper. We give some relationships between the modulus and the Mazur-Orlicz F-norm. We obtain an interesting result that the norm of an element in line segments is formed by two elements on the unit sphere less than or equal to 1 if and only if that the monotone function is a convex function. The criterion that Orlicz spaces and Orlicz sequence spaces that are generated by monotone function equipped with the Mazur-Orlicz F-norm are strictly monotone or lower locally uniform monotone is presented.
