Background  The study determined to compare the clinical outcomes of traditional gold weight implantation for the correction of paralytic lagophthalmos with those of a newly designed model. Methods  In this retrospective cohort study, we enrolled 30 patients (76% females; average age 60.8 ± 12 years) with facial palsy who underwent implantation of either the traditional pretarsal gold weight (PT group; n  = 15) or a new supratarsal model (ST group; n  = 15) from May 2014 to April 2019. The main outcome measures were the 12-month postoperative weight prominence, weight migration, improvement of lagophthalmos, upper eyelid contour, and upper eyelid ptosis. The secondary outcome was long-term (24 months) reoperative rate. Results  The new model group had significantly better eyelid contour (risk ratio [RR] 3.16, 95% confidence interval [CI] 1.62-6.15, p  = 0.001), less weight prominence (RR 1.74, 95% CI 1.13-2.70, p  = 0.013), less weight migration (RR 1.31, 95% CI 1.12-1.54, p  = 0.001), and less eyelid ptosis (RR 2.36, 95% CI 1.21-4.59, p  = 0.011) than the traditional model group. Improvement of lagophthalmos was not statistically significant between the two groups (RR 1.44, 95% CI 0.72-2.91, p  = 0.303). The 24-month reoperative rate was 53.3% in the PT group versus 13.3% in the ST group (RR 2.00, 95% CI 1.15-3.49, p  = 0.015). Conclusion  The newly designed supratarsal gold weight showed superior postoperative outcomes than the standard traditional model.

BACKGROUND: Loss of vision and other ocular defects are a concern with eyelid burn sequelae. This most commonly progresses from eyelid contracture to cicatricial ectropion and lagophthalmos. When left untreated, these may lead to exposure keratitis, ulceration, infection, perforation, and loss of vision. In the case of full-thickness eyelid burns, release and grafting are required. However, there is a paucity of studies on outcomes in eyelid burn surgery treatment, despite concern for permanent ocular damage or loss of vision. The aim of the study is to describe the complication rates in burn eyelid reconstruction at a single center for 14 years.
METHODS: A retrospective cohort study was performed of all patients who had sustained eyelid burns and required reconstruction between April 2009 and February 2023. Medical records were obtained from patients\' charts. Collected data include demographics, medical history, type of injury, indication for surgery, procedure performed, and complications.
RESULTS: A total of 14 patients and 25 eyelids underwent eyelid reconstruction of the 901 total patients with burn-related injuries requiring plastic surgery reconstruction. These patients underwent 54 eyelid surgeries with a mean follow-up time of 13.1 ± 17.1 months. Patients were 71% men and 29% women, with a mean age of 45.1 ± 15.6 years. In 53.7% (n = 29) of the cases, the simultaneous reconstruction of both the upper and lower eyelids was necessary. The reconstruction of the upper and lower eyelid alone represented a smaller percentage (25.9% and 20.4%, respectively). On average, the patients received 3.9 ± 3.5 eyelid surgeries. The overall complication rate was 53.7% (n = 29). The most common complication was ectropion (42.6%, n = 23). Other complications included eye injury (25.9%, n = 14), lagophthalmos (24.1%, n = 13), local infection (7.4%, n = 4), and graft loss (5.6%, n = 3).
CONCLUSIONS: Periorbital burns represent a major challenge that may require complex surgical intervention. Full-thickness skin graft remains the standard of care for patients with eyelid burns. However, there is a high incidence of ectropion that may require reoperation. Further studies examining the conditions of successful eyelid burn procedures may provide guidance on when patients may benefit from eyelid reconstruction during their burn treatment.

OBJECTIVE: Despite various existing surgical techniques, treatment of facial nerve palsy remains difficult. The purpose of this report is to present the cerclage sling technique using temporalis fascia to manage paralytic lagophthalmos.
METHODS: A series of six patients underwent a cerclage sling technique using temporalis muscle fascia to treat paralytic lagophthalmos. The technique is presented in detail. Symptoms, palpebral fissures, and lagophthalmos were assessed pre- and postoperatively. Data were submitted for statistical analysis.
RESULTS: After surgery, all patients achieved a reduction in clinical symptoms. The upper eyelids had lowered, and the inferior eyelids had elevated, reducing ocular exposure even if mild residual lagophthalmos was present.
CONCLUSIONS: Cerclage using the temporalis muscle fascia sling technique is a safe and effective procedure to treat facial nerve paralytic lagophthalmos. A reduction in ocular exposure and lagophthalmos provides improvement in clinical symptoms and eyelid function.

BACKGROUND: Even though upper blepharoplasty is one of the most commonly performed procedures in esthetic surgery, there is still no consensus regarding the management of the orbicularis oculi muscle (OOM).
OBJECTIVE: To compare outcomes of upper eyelid blepharoplasty with or without OOM excision using surface electromyography in a 12 month follow-up.
METHODS: A prospective, randomized, single-blinded comparative split-face study was conducted on 26 patients with dermatochalasis. Skin-only upper blepharoplasty was performed on a randomly selected side, and on the contralateral side, a strip of OOM was resected as well. The functional outcomes were assessed using sEMG, and the esthetics were evaluated independently by the operating surgeon, blinded patients, and three blinded ophthalmic surgeons.
RESULTS: The RMS values of maximal contraction of the OOM were statistically significantly lower two weeks after blepharoplasty than the values before surgery in both groups (p < 0,001) and reached the preoperative values after six months. Lagophthalmos occurred in 2 cases in the skin-muscle group (7.69%), and no incidence of lagophthalmos was observed in the skin group. There were comparable esthetic outcomes on both operated sides.
CONCLUSIONS: This study is an objective and quantitative report using surface electromyography on upper blepharoplasty with or without a strip of OOM excision. Our results showed that OOM fully recovers after the stripping procedure. The resection of the skin-OOM flap showed no difference in long-term cosmetic results. Therefore, we recommend OOM preservation during upper blepharoplasty unless muscle excision is well-grounded.

OBJECTIVE: To identify clinical and epidemiological characteristics of patients with peripheral facial palsy (PFP) at a tertiary care hospital.
METHODS: This is a retrospective observational study of patients with PFP treated at a tertiary medical center. We gathered demographic data, etiology, laterality, recurrence, recovery, clinical ophthalmology, severity according to the House-Brackmann (HB) scale, electrophysiological tests, medical services attended, medical and surgical treatment.
RESULTS: Two hundred and eighty-three PFP were included, 135 (48%) were men and 148 (52%) were women p = 0.47). All patients had unilateral involvement. The mean age was 54 ± 20 years. The main etiology was idiopathic in 215 (76%) patients. Median recovery time was 7 weeks. Recovery was complete in 190 (67%) patients. One hundred and seventy (84%) patients with idiopathic PFP had complete recovery, versus 30 (16%) patients with non-idiopathic PFP (p < 0.01). The 84% of patients with HB grade II, recovered completely, while with HB grade VI only 17% recovered (p = 0.003). Two hundred and twenty-nine patients (81%) had lagophthalmos. The majority received ocular surface care treatment in 271 (96%) patients and of these 249 (88%) patients received oral corticosteroid therapy. Thirteen patients (5%) required ophthalmologic surgery.
CONCLUSIONS: PFP affects all age ranges, without predilection for sex and unilateral. Its main cause is idiopathic. Recovery is complete in most cases, being more favorable in mild and idiopathic affections. Most only require medical treatment.

To investigate the changes in eyelid blinking dynamics after external dacryocystorhinostomy (DCR).
Prospective before-and-after study with follow-up.
Patients undergoing external DCR surgery for primary acquired nasolacrimal duct obstruction were observed using high-speed videography that recorded eyelid blinking of both eyes for a total duration of 4 minutes at a rate of 120 frames per second. These recordings were taken before the surgical procedure, on postoperative day 3, and then at 1 week, 1 month, and 3 months after the DCR surgery. A total of 3 random blinks were selected and isolated from each video recording for data analysis. For each blink, lagophthalmos and eyelid blinking velocity were calculated for the operated eye, and their values were then compared with those calculated for the contralateral, nonoperated eye.
Data were obtained for 22 patients. Operated eyes showed large postoperative lagophthalmos on postoperative day 3, with a mean of 56.58% ± 52.63% of the palpebral fissure height. Gradual improvement of the lagophthalmos occurred over the next follow-up visits, and reached a mean of 31.24% ± 36.71% at follow-up visit 3 months postoperatively. The velocity of eyelid blinking showed a significant reduction for the operated eyes, with gradual improvement over 3 months.
Postexternal DCR eyelid blinking changes included significant blink lagophthalmos with decreased velocity of eyelid blinking which gradually improved over the 3-month follow-up period. A longer follow-up period may be required to confirm if eyelid blinking lagophthalmos and velocity will return to baseline levels.

Palpebral eyelid weight implants are currently considered as the gold standard method for lagophthalmos correction. Manufactured from different precious metals, they have both benefits and drawbacks. The article presents the results of an experimental morphological study of biointegration of different eyelid weight implants used for correction of paralytic lagophthalmos.
OBJECTIVE: To investigate biointegration properties of implants made of gold, platinum and platinum-gold alloy.
METHODS: The study enrolled 4 Chinchilla rabbits (8 eyelids). Palpebral implants manufactured of gold, platinum and platinum-gold alloy were placed into the eyelids of the experimental animals. The morphological examination was performed 1 and 6 months after the implantation using paraffin sections.
RESULTS: Light microscopy revealed that the implant beds were surrounded by pronounced fibrovascular capsule of uneven thickness over the whole follow-up. The capsule formed after the placement of an implant made of gold and platinum alloy was more loose. However, the emerging connective tissue bridges of the capsule contributed to its immobilization in the tissues and lower risk of extrusion. No signs of an inflammatory and/or allergic reaction were observed in any of the cases.
CONCLUSIONS: The obtained results show that implants made of a 90/10% platinum-gold alloy and 999.9 fine platinum have similar biointegration in terms of morphological features during 6 months of the follow-up period.
Утяжеляющие пальпебральные имплантаты являются современным стандартом коррекции паралитического лагофтальма. Изготовленные из различных благородных металлов имплантаты имеют свои преимущества и недостатки. В настоящем экспериментально-морфологическом исследовании представлены результаты биоинтеграции имплантатов из золота, платины и сплава платины с золотом для коррекции паралитического лагофтальма.
UNASSIGNED: Выявить морфологические особенности биоинтеграции пальпебральных имплантатов из различных металлов и их сплавов.
UNASSIGNED: Работа выполнена на 4 кроликах породы шиншилла (8 век), которым были установлены пальпебральные имплантаты из разных материалов (платина, платина и золото, золото). Результаты оценивали на сроках 1 и 6 мес после постановки имплантатов по данным морфологического исследования парафиновых срезов.
UNASSIGNED: По данным световой микроскопии, на всех сроках наблюдения ложе установленных имплантатов было выстлано достаточно выраженной, неравномерной по толщине фиброваскулярной капсулой. После постановки имплантата, выполненного из сплава золота и платины, отмечено формирование более рыхлой капсулы. Однако формирующиеся соединительно-тканные перемычки капсулы способствовали его иммобилизации в тканях и меньшему риску экструзии. Признаки воспалительной и/или аллергической реакции отсутствовали во всех случаях.
Заключение. Экспериментальные данные позволяют сделать вывод, что постановка имплантатов, выполненных из сплава платины и золота в соотношении 90/10% и платины чистотой 999,9, сопровождается практически тождественной морфологической картиной биоинтеграции на сроке анализа 6 мес.

UNASSIGNED: Lower eyelid management is challenging. The conchal cartilage is often considered a spacer of choice for treating lower eyelid retraction. However, dermis graft has also recently been shown to be a viable spacer. The aim of this study was to compare the efficacy of dermis graft to that of conchal cartilage graft in this indication.
UNASSIGNED: A retrospective comparative study was conducted in patients who underwent lower eyelid lengthening with autologous dermis graft (group 1) or autologous conchal cartilage graft (group 2). The main outcome measure was the reduction in inferior scleral show (ISS) assessed by three independent masked surgeons. Secondary outcome measures was the assessment of lagophthalmos and corneal keratitis. Complications were also recorded.
UNASSIGNED: Twenty-five eyelids of 23 patients were included: 11 and 14 eyelids, respectively in group 1 (dermis graft) and group 2 (conchal cartilage graft). Patient mean follow-up was 12.3 (±12.5) and 7.1 (±7.7) months, respectively. No statistical differences in postoperative ISS reduction, lagophthalmos and exposure keratitis was observed (p = 0.540, p = 0.946, p = 0.934, respectively). Three patients experienced a grade I Clavien-Dindo complication in group 1 and one patient experienced a grade II complication in group 2 (p = 0.540).
UNASSIGNED: Autologous dermis grafts and conchal cartilage grafts provide favorable outcomes without major complications.

To study the prevalence of lagophthalmos and its related complications among the unconscious patients admitted in the intensive care units (ICU)/wards of a tertiary care centre.
Cross-sectional observational study.
A total of 87 unconscious patients were included. 44 were children and 43 were adults. The overall median age of patients was 16 years (range: 9 days- 85 years). 53/87 (60.91%) showed signs of lagophthalmos, among which 56.60% (30/53) were children and 43.40% (23/53) were adults. There was no significant difference in the exposure patterns between children and adults (p = 0.25). Exposure related manifestations (conjunctival/corneal) were found in 49/87 patients (56.32%). The most common conjunctival manifestation was chemosis, occurring in 28/53 patients (52.83%). Corneal exposure was seen in 31/53 patients (58.49%), of which fragile epithelium was the commonest finding (32.08%). Only 17/31 (54.83%) cornea exposed eyes were taped, of which 15 were sub-optimal. 6 patients were unnecessarily taped. Signs of infection were noted in 8/53 eyes (15.09%).
Optimal eye care in unconscious patients can avert the development of exposure-related complications and subsequent ocular morbidity. Adoption and implementation of systematic protocols can help improve the standard of care.

OBJECTIVE: To study the effect of autogenous fascia lata sling (AFLS) versus Gore-Tex suspension (GTS) regarding the functional and aesthetic outcomes in patients with bilateral congenital ptosis.
METHODS: A prospective comparative randomized single-center study enrolled 110 patients with bilateral congenital ptosis. One group (n=55) underwent AFLS and the second group (n=55) underwent GTS. Exclusion criteria were good levator function, absent Bell\'s phenomenon, and abnormal ocular motility. Follow-up period was 2 years. Functional outcome was measured from digital photos by analysis of upper eyelid margin position relative to the superior limbus and classified as very good (<3 mm), good (3-5 mm), poor (>5 mm), and recurrent. Aesthetic outcome was assessed in terms of lid contour, symmetry of eyelid height, and lid crease presence. Complications were also reported.
RESULTS: Failure rate (recurrence and complications) was less in AFLS (P=0.035). Symmetrical lid height and good contour were more frequently attained by AFLS (P=0.007 and 0.047, respectively). However, the frequency of very good, good, poor, recurrence, lagopthalmos, ectropion, infection, and formed lid crease individually showed no statistically significant difference (P=0.252, 0.482, 1, 0.489, 0.438, 1, 0.618, and 0.506, respectively).
CONCLUSIONS: AFLS is a better choice in surgery for patients with bilateral congenital ptosis because it has fewer complications and a lesser recurrence rate than GTS.
