Senile trichiasis is primarily manifested by eyelid laxity, decreased horizontal elasticity and tension of the eyelids, leading to friction between the eyelashes and the cornea, which subsequently causes corneal damage and vision decline. Surgical intervention remains the most effective therapeutic approach for senile trichiasis. This article elaborates on the epidemiological characteristics, pathological mechanisms, and clinical manifestations of senile trichiasis and systematically reviews the surgical treatment method for upper and lower eyelid trichiasis, including traditional surgical techniques and emerging minimally invasive procedures combined with personalized therapies. Through a literature review, the effectiveness and recurrence rates of surgical treatment are summarized, emphasizing the importance of preoperative assessment and individualized treatment. Additionally, strategies and recommendations for preventing senile trichiasis are proposed.

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 investigate the applicability and surgical effect of direct horizontal suture in the repair of defects after the excision of eyelid nevus.Methods:The clinical data of patients with eyelid nevus who were admitted to Department of Facial and Neck Plastic Surgery, Plastic Surgery Hospital of Chinese Academy of Medical Sciences from March 2015 to March 2023 were retrospectively analyzed. After the eyelid nevus was removed, the defect was closed by horizontal suture parallel to the eyelid margin. In the preoperative simulation suture scheme, one or more horizontal lines were marked on the eyelid skin according to the scope of the nevus. The intersection points of the horizontal lines and the edges of the nevus were marked for simulated suturing. If the marked points aligned horizontally, direct suturing was applied. After 3 months of postoperative follow-up, the therapeutic effect was evaluated based on eyelid function (classified as excellent, good and poor), cosmetic effects (classified as excellent, good and poor) and patient satisfaction (classified as very satisfactory, satisfactory and dissatisfactory). At the same time, the effect of different wound length (<1 cm, 1-2 cm, >2 cm) on the therapeutic effect was also analyzed. SPSS 27.0 software was used for statistical analysis of the data. The counting data were represented by examples and percentages, and Kruskal-Wallis H test was used for comparison between groups. P<0.05 indicated that the difference was statistically significant. Results:A total of 71 patients were enrolled, including 30 males and 41 females. Aged 4 to 35 years old, with an average age of 15 years old. The lesions involved the upper eyelid in 47 cases, the lower eyelid in 14 cases, and co-involved in 10 cases. Lesion areas ranged from 0.5 cm×0.5 cm to 2.3 cm×2.0 cm. None of the lesions involved the palpebral margin and conjunctiva, and the depth did not reach the orbicularis oculi muscle. Immediately after the operation, all the patients had different degrees of eyelid deformation, and some severe patients had difficulty opening their eyes. The above symptoms were relieved within 7 days to 3 months after the operation, and eventually the eyelid movement returned to normal, leaving only mild scarring. In cases where the eyelid nevus was close to or involved the eyebrow area, eyebrow shape changed after surgery, and it gradually returned to normal after 1 month. Some patients with part of the eyebrow defect were able to improve their appearance through eyebrow tattoos, eyebrow transplatation and other methods. The eyelid function of 71 patients was excellent. The evaluation of cosmetic effect, 41 cases (58%) were excellent, and 30 cases (42%) were good. The evaluation of patient satisfaction, 56 cases (79%) were very satisfied, and 15 cases (21%) were satisfied. Statistical analysis showed that with the increase of the horizontal length of the wound, the cosmetic effect and patient satisfaction would be affected to a certain extent, but the differences were not statistically significant ( P>0.05). Conclusion:For eyelid nevus excision defects that can be closed horizontally, direct suturing method should be considered priority. This method is simple to perform, offers stable postoperative effects, and leads to high patient satisfaction.

Objective:To investigate the feasibility of a new clinical grading scale for assessing the degree of laxity of upper eyelid skin.Methods:From May 2022 to October 2023, the patients who underwent upper eyelid skin laxity plastic surgery in the Department of Plastic Surgery and Burns-Department of Medical Cosmetology, Northern Jiangsu People’s Hospital Affiliated to Yangzhou University, were prospectively enrolled. The degree of upper eyelid skin laxity was graded independently by three plastic surgeons who did not participate in the operation according to the grading scale and using facial photographs of the patients.The clinical grading scale categorizes the degree of skin laxity into 4 grades ranging from 0 to 3 degrees, by analyzing the position of the lower edge of the upper eyelid skin relative to the upper eyelid edge and the pupil, and the higher the grade, the more serious the degree of skin relaxation. If bilateral upper eyelid skin laxity were presented, the grade of the side with more severe laxity was taken as the grade of the upper eyelid skin laxity of the patient. The Kendall coefficient (range -1-1) of the three doctors’ grading result before and after operation was calculated respectively. The closer the value was to 1, the better the consistency of the three doctors, and the better the stability of the grading scale. The degree of upper eyelid skin laxity before and after operation was expressed as M ( Q1, Q3), and the paired Wilcoxon signed rank test was used for comparison. Results:A total of 50 female patients aged 32 to 67 years old (mean 45.3 years) who underwent bilateral upper eyelid skin laxity plastic surgery were enrolled. The Kendall coefficients of the grading result of the upper eyelid skin laxity of 50 patients by three doctors before and after operation were 0.975 and 0.882, respectively ( P<0.01). It suggested high consistency among evaluators for the same patient. 50 patients were graded as 2(1, 2) degree and 0(0, 0) degree preoperatively and postoperatively, respectively, indicating that the degree of upper eyelid skin laxity was significantly improved postoperatively. The result of Wilcoxon signed rank test showed that there were significant differences in preoperative and postoperative grading result of the three doctors ( P<0.01). Conclusion:The grading scale of upper eyelid skin laxity is objective and easy to use. Its evaluation result are stable and repeatable, and it can effectively analyze the changes of the degree of upper eyelid skin relaxation before and after surgery.

Objective:To summarize the characteristics and treatment strategies of tissue expander infections in auricular reconstruction using tissue expansion, providing references for the prevention and treatment of expander infections.Methods:A retrospective analysis was conducted on the data of patients who underwent auricular reconstruction using tissue expansion from January 2018 to January 2024 in the Plastic Surgery Hospital of Chinese Academy of Medical Sciences. Patients meeting the inclusion criteria were included in the study. The causes of expander infections were summarized. Infections were categorized based on time periods (perioperative, inflation period, skin expansion period) and severity (mild, severe). The management and healing outcomes of different types of expander infections were recorded and their incidence rates were calculated. Descriptive statistical method were employed for analysis.Results:A total of 39 patients were included, with 25 males (64.1%) and 14 females (35.9%). The age was (8.2 ±1.9) years (range 5-13 years). Regarding infection causes, folliculitis of the expanded flap was noted in 9 cases (23.1%), inflation procedures in 10 cases (25.6%), insect bites in 2 cases (5.1%), and no obvious cause in 18 cases (46.2%). Perioperative infections occurred in 3 cases (7.7%), inflation period infections in 30 cases (76.9%), and skin expansion period infections in 6 cases (15.4%). Mild infections were present in 21 cases (53.8%) and severe infections in 18 cases (46.2%). After successful treatment of expander infections, 34 patients (87.2%) completed the second stage of reconstruction, while the remaining 5 cases(12.8%) had the expander removed and received ear reconstruction six months later.Conclusion:Infections of expanders during auricular reconstruction using tissue expansion are more common during the inflation period. Early management of potential causes of expander infections can reduce the risk of infection.

Keloids are abnormal scar tissues that form as a result of the skin’s excessive reaction to trauma or stimulation. The primary pathological feature of keloids is the excessive deposition of extracellular matrix components in the dermis and subcutaneous tissue. Currently, surgical resection combined with postoperative radiotherapy is one of the most effective treatment strategies. However, there is no standardized protocol regarding the timing, specific methods, and dosage of radiotherapy. This paper reviewed existing research on radiotherapy following keloid surgery, summarizing the various radiotherapy regimens and associated complications to provide a reference for the treatment and management of keloids.

Aging has always been a topic that has been widely concerned and discussed. The aging of lower eyelid starts to accelerate after the age of 40 years, which is an important indicator of people’s perceived age, mainly manifested as the emergence of tear trough, palpebromalar groove, eyelid bags, and skin aging. It is of great significance to evaluate the state of lower eyelid completely and objectively for the aging degree of lower eyelid, the formulation of individualized treatment plan and the evaluation of surgical effect. This article reviews the current status and progress of lower eyelid assessment method in recent years.

This paper reported the clinical manifestations, pathological features, immunophenotype and follow-up of two patients with superficial CD34-positive fibroblastic tumor (SCPFT), who were admitted to Shandong Provincial Hospital in 2022 and 2023, and discussed the relevant literatures. The two patients, aged 43 and 20 years old, were both male. Their tumors were located in the perineum and the back of left shoulder, respectively. Both presented as single slow-growing subcutaneous masses with a course typically measured in years, accompanied by mild tenderness but without pain or pruritus. Microscopically, spindled to epithelioid cells and pleomorphous nuclear cells arranged in cellular fascicles and solid sheets were the main findings. Immunophenotypically, positive expression of CD34 was found in both cases. Extended resection ensured negative marginal and basal margins for both cases. No recurrence was observed after 22 and 12 months of follow-up, respectively. Clinical features, pathology, and differential diagnosis were discussed and summarized through a review of relevant literature. SCPFT is a novel type of fibroblastic tumor categorized as a low-grade malignant soft tissue tumor with unique pathological and biological characteristics that is relatively rare clinically. Routine resection may lead to recurrence; therefore, long-term follow-up is necessary. The combination of morphological characteristics and immunohistochemistry is helpful to diagnosis. It is important to differentiate this disease from other tumors to avoid misdiagnosis or mistreatment.

In September 2023, a 40-year-old female patients with correction failed mallet finger was admitted to Department of Hand and Foot Microsurgery, Nanjing Jiangbei Hospital. After comparing with different surgical options, the method of bundling bone fragment with double figure-of-eight suture was adopted to correct the failed mallet finger. At 3 months follow-up, the mallet finger deformity was corrected. The active extension function of the distal interphalangeal joint (DIPJ) of the affected finger was restored, the DIPJ straighten to 0°, and the appearance of the finger was satisfactory.
