Objective:To investigate the clinical effect of local perforator advancement flap in repairing mid-face soft tissue defects and its correlation between with the three dimensional configuration of the skin ligament.Methods:1) 12 fresh adult cadaver specimens (7 males, 5 females, aged 54-87 years) were selected. After dehydration and degreasing of the cadaver head with acetone, plasticized and sliced with a fully transparent ultra-thin layer of epoxy resin, using a Leica MZ8 stereo microscope and a Leica DFC295 digital camera to observe and analyze the prepared slices, and observe the differences in the three-dimensional structural characteristics of the cutaneous ligaments in different parts of the midface (cheek, nose, orbital eyelid) . (2) A retrospective analysis was made of the case data of midface soft tissue defects admitted to the Plastic Surgery Department of the First Affiliated Hospital of Anhui Medical University from January 2015 to October 2021. All patients were repaired with local perforator advancement flap. The Pearson bivariate correlation test was used to analyze the correlation among flap advancement distance, flap area, flap aspect ratio, and defect size. The Kruskal-Wallis test was used to analyze the differences of flap area and flap aspect ratio in different parts of the midface.Results:1) Anatomical studies have shown that the running direction of the facial skin ligaments is the same as that of the expressive muscles, and their three-dimensional structures at the upper eyelid and the nasal and facial corners of the upper nasal alar are different. The upper eyelid skin ligaments run along the eyelid, while the upper nasal The supracutaneous ligaments run down the alar of the nose. (2) The clinical study included 18 patients, 8 males and 10 females, aged (65.1±22.9) years. The flaps of 18 patients survived after operation, the flap area was (13.85±9.38) cm 2, and the advancing distance was (1.94±0.75) cm. Statistical analysis showed that there was a correlation between the flap advancement distance and the flap incision area ( r=-0.712, P=0.022) and the flap aspect ratio ( r=-0.580, P =0.012). There was no correlation with the defect area ( r=-0.227, P=0.365) ; the aspect ratios of the cheek, nose and orbital lid flaps were 2.06±0.42 , 2.50±1.18, 3.25±0.93, and the differences were statistically significant ( H= 6.59, P=0.037). Conclusions:The local perforator advancement flap is an ideal method for repairing midface soft tissue defects. The differences in the construction of the skin ligaments in different parts of the mid-face will affect the ease of advancement of the flaps and other characteristics in each part, which may be the reasons for affecting the aspect ratio of the flap design.

Objective:To explore the clinical effect of frontalis muscle flap combined with check ligament double suspension in the treatment of severe blepharoptosis.Methods:13 patients(16 eyes) who were almost zero muscle strength with severe blepharoptosis, was treated with double eyelid incision. Check ligament was isolated from the superior conjunctival fornix which was between the superior rectus muscle and the levator eyelid muscle. Then the upper edge of the tarsal plate was fastened so that the upper eyelid margin can be raised by about 2-3 mm. The forehead muscle flaps formed by the post separation of septa orbitale were sutured and fixed at the lower end of the check ligament, and the height of the upper eyelid was increased dynamically to about 1-2 mm above the cornea.And then the effect of this operation was evaluated and the efficiency was calculated after operation.Results:There were 13 cases which include 16 eyes in our group. Stitches were taken out 7 days after the operations, and the incisions healed well. All the upper eyelid margins were located at about 1-2 mm above the cornea when they opened the eyes. These eyes were all accompanied by different degrees of hypophasis when they closed. All of the patients in our group were followed up effectively for 4 to 12 months. Twelve eyes were greatly corrected. Three eyes were moderately corrected. And only one eyes were corrected insufficiently. The overall effective correction rate was about 93.75%. The correction effect was satisfactory. No complication, such as exposed keratitis, ectropion and conjunctival prolapse were found in all cases.Conclusions:The double suspension of frontalis muscle flap combined with check ligament can effectively increase the height of upper eyelid margin, which is beneficial for the accurate rectification effect, stable long-term effect and little complications. It is suitable for the correction of severe upper eyelid sag with extremely weak muscle strength of upper eyelid lifter.
