Objective:To investigate the clinical efficacy of the upper eyelid orbicularis oculi muscle bicuspid flap in the correction of excessive width deformities following incisional double eyelid blepharoplasty.Methods:A retrospective analysis was conducted on 30 female patients with excessive width deformities after incisional double eyelid surgery, treated at Sichuan Provincial People′s Hospital between June 2022 and June 2023. The patients′ ages ranged from 30 to 55 (43.1±6.9) years. All patients underwent primary correction using the upper eyelid orbicularis oculi muscle bicuspid flap technique. Preoperative incision lines were designed, and intraoperatively, previous adhesions were thoroughly released. Residual orbicularis oculi muscle was identified superficial to the orbital septum, and both superficial and deep surfaces of the muscle were dissected. The transitional zone between the orbicularis oculi and frontalis muscle was transversely transected deep to the orbital rim, while preserving the medial and lateral attachments of the orbicularis oculi to create a double-pedicle flap. After flap creation, it was repositioned inferiorly to the anterior surface of the tarsal plate along the incision line. This maneuver prevented direct adhesion between the skin and the levator palpebrae superioris muscle and established a tissue step-off, thereby forming a new, natural double eyelid fold. Outcomes were evaluated at 6 months postoperatively, including double eyelid width, fold morphology, scar appearance, complications, and patient satisfaction.Results:The postoperative double eyelid width was (1.9±0.4) mm, significantly reduced from the preoperative width of (5.7±0.9) mm ( P<0.001). The postoperative morphological score was (-0.1±0.6), significantly improved compared to the preoperative score of (-2.4±0.9) ( P<0.001). There was no statistically significant difference in scar scores before (1.7±1.3) and after (1.6±0.8) surgery ( P=0.459). Overall patient satisfaction was 90% (27/30). No major complications such as infection, upper eyelid hollowing, multiple folds, obvious scarring, significant hematoma, persistent bleeding, or lagophthalmos occurred; all patients achieved primary healing. Three patients exhibited mild bilateral asymmetry, and two reported a foreign body sensation in the eye. Conclusions:The upper eyelid orbicularis oculi muscle bicuspid flap is an effective technique for correcting excessive width deformities following incisional double eyelid surgery. It results in reduced eyelid width, natural fold formation, minimal complications, and high patient satisfaction.

Objective:To investigate the correlation between serum calcitonin gene-related peptide (CGRP) and the culture outcome of in vitro fertilization embryo in male patients with infertility.Methods:In this study, the randomized samples from 25 male patients who received in vitro fertilization-embryo transfer (IVF-ET) in the 1st Affiliated Hospital of Fujian Medical University from June 2019 to October 2019 were analyzed by multiple linear stepwise regression, with some important clinical outcomes, such as the logarithmic conversion index of serum CGRP, fertilization method, masturbation difficulty, age, infertility duration, and prolactin, as independent variables, while total fertilization rate, normal fertilization rate, high quality embryo rate at day 3, blastocyst formation rate as dependent variables.Results:The Pearson correlation analysis showed that the D3 high-quality embryo rate was related to the normal sperm morphology rate in the primary infertility group ( r=0.537, P=0.048), the blastocyst formation rate was correlated with sperm density ( r=0.760, P=0.002), the CGRP logarithm was correlated with the total fertilization rate ( r=0.693, P=0.006). The logarithmic conversion index of serum CGRP was related to the total fertilization rate and normal fertilization rate in the secondary infertility group ( r=0.614, P=0.042 and r=0.611, P=0.046). In the secondary infertility group, there was a linear relationship between normal fertilization rate and total sperm count, serum CGRP log conversion, and sperm normal morphology rate, with standardized regression coefficients of 0.2, -0.729, and 6.8, respectively. Conclusion:Serum CGRP level, together with total sperm count and normal sperm morphology rate may affects normal fertilization rate in male patients with infertility.
