Outcome Comparison of Transconjunctival Müller's Muscle Recession With Levator Disinsertion (TMRLD) to Gold Weight Implantation in the Treatment of Paralytic Lagophthalmos.

To compare clinical outcomes of transconjunctival Müller's muscle recession with levator disinsertion (TMRLD) to the traditional gold weight implantation in patients with paralytic lagophthalmos. A retrospective nonrandomized comparative review of patients who had gold weight implantation and TMRLD surgeries for paralytic lagophthalmos from January 2016 to January 2023 was performed. The main outcome comparisons were measurement changes in lagophthalmos, marginal reflex distance 1, visual acuity, and corneal examination. Complication and reoperation rates were also compared. Twenty-six cases of gold weight implantation and 20 cases of TMRLD surgeries were identified. The changes in logMAR visual acuity between gold weight implantation and TMRLD groups were not statistically significant (-0.10 ± 0.48 vs. +0.05 ± 0.14, p > 0.05). The percent improvement in lagophthalmos (62.2% ± 51.8% vs. 58.4% ± 21.1%) and final marginal reflex distance 1 (2.22 ± 1.42 vs. 2.25 ± 1.41 mm) were also comparable between groups ( p > 0.05). Both groups showed similar changes in marginal reflex distance 1 (1.75 ± 1.31 vs. 2.83 ± 1.37 mm) and lagophthalmos (3.77 ± 3.92 vs. 3.36 ± 1.36 mm) ( p > 0.05). The overall complication (15.4% vs. 15.0%) and reoperation rates (15.4% vs. 15.0%) were comparable over the follow-up duration (291.6 ± 437.3 vs. 121.0 ± 177.8 days) ( p > 0.05). TMRLD is as safe and effective as the gold weight implantation in addressing paralytic lagophthalmos in patients with facial nerve palsy.

Tape Eyelid Closure: An Effective Solution for Nocturnal Lagophthalmos in Patients with Ptosis and Poor Bell's Phenomenon.

Poor Bell's phenomenon is often considered a relative contraindication for ptosis surgery, as it increases the risk of corneal exposure and dry eye symptoms after surgery. However, the Bell's phenomenon may vary in different individuals and sleep stages, making it inaccurate to predict the position of the eye during sleep based on awake examination. This study aimed to investigate the role of Bell's phenomenon in ptosis surgery and the management of nocturnal lagophthalmos. We conducted a retrospective case series of 23 patients with ptosis and poor Bell's phenomenon who underwent different surgical techniques at Xijing Hospital from April 2020 to June 2021. We assessed Bell's phenomenon at different stages of sleep and collected data on ptosis degree, surgical approach, lagophthalmos, complications, and outcomes. Of the total 23 patients originally considered for study, 9 with frontalis muscle advancement technique, 8 with conjoint fascial sheath suspension, 4 with levator resection technique, and 2 with levator aponeurosis plication technique. All patients achieved satisfactory correction of ptosis. One patient had prolonged lagophthalmos and underwent reoperation to lower the eyelid height. Other complications were minor and resolved with conservative treatment. We conclude that poor Bell's phenomenon is not a relative contraindication for ptosis surgery. Nocturnal lagophthalmos should be monitored after ptosis surgery regardless of the Bell's phenomenon results. Tape eyelid closure can be an effective solution to protect the corneal surface during nocturnal lagophthalmos. This journal requires that authors assign a level of evidence to each article.

Зависимость клинических проявлений паралитического лагофтальма от уровня и давности поражения лицевого нерва

The path of the facial nerve is associated with multiple nerves, bones and soft tissues, including n. trigeminus, n. intermedius, petrosal bone and parotid gland. Due to this fact, facial palsy results not only in lagophthalmos but also in dysfunction of tear production and even vision lost in some cases. The aim of the study is to compare clinical signs of lagophthalmos in patients with various levels and duration of facial palsy. We analyzed 120 cases of lagophthalmos in patients aged 5–90 y.o. with duration of facial palsy from 2 month to 90 years. The patients were divided into 4 groups according to the level of nerve damage: 1 – in the cerebral part of the nerve, 2 – in petrosal bone, 3 – in the area of parotid gland, and 4 – indefinite. The light forms of keratopathy were dominant in all of the groups (72.5 %). There was a very weak correlation between the duration of facial palsy and margin to the low limb distance (r = 0.190; p < 0.05). The width of the eye fissure was significantly different between 1st and 3rd groups (p = 0.019), 1st and 4th groups (p = 0.042), 2nd и 3rd (p = 0.038), 2nd and 4th (p = 0.043). Although the results of Schirmer 1 tests was significantly different only between 1st and 3rd groups (p < 0.001). Severity of clinical signs in paralytic lagophthalmos depends in most on the level of facial nerve damage and can be due to concurrent damage of n. trigeminus. The duration of the facial palsy and involvement of n. intermedius do not play any significant role.

Modified tarsorrhaphy versus gold weight implant technique for paralytic lagophthalmos treatment in patients with leprosy: One-year observation of a randomized controlled trial study.

This study was a multicenter, Prospective Randomized Open-label Blinded-Endpoint (PROBE) clinical trial, parallel-group study conducted in Indonesia (three sites). The aim of this study was to compare the effectivity and efficiency of modified tarsorrhaphy (MT) and gold weight implant (GWI) techniques in the surgical treatment of paralytic lagophthalmos in patients with leprosy. The study sample consisted of 23 eyes, with 11 eyes in the MT group and the remaining 12 eyes in the GWI group-the control group. The central eyelid margin distance (lagophthalmos distance) decreased when gentle pressure was applied in the MT (3.09 mm to 0.43 mm) and GWI groups (3.21 mm to 0.83 mm) at postoperative year 1. The Ocular Surface Disease Index score, the tear break-up time, and the Schirmer test without and with anesthesia in the MT and GWI groups showed a p-value of > 0.05. Epitheliopathy improvement occurred in 54.55% of the MT group and 58.33% of the GWI group. Corneal sensitivity change in the inferior quadrant of the MT group (50.00 to 51.30 mm) and in the GWI group (49.61 to 52.93 mm) resulted in a p > 0.05. Postoperative complications occurred in 15% of patients in the GWI group. In addition, the surgery duration of both techniques was similar. Furthermore, the surgery cost in the MT and GWI groups yielded a p < 0.05. The MT technique is as effective as the GWI technique but more efficient than the GWI technique as a surgical treatment for paralytic lagophthalmos in patients with leprosy.

Intraoperative lagophthalmos formula for levator resection in congenital ptosis.

To calculate a regression formula for intraoperative lagophthalmos to determine the amount of correction in levator resection for mild to moderate congenital ptosis. This retrospective study included 38 eyelids from 28 consecutive children with congenital ptosis with levator function of 4 mm or better who showed satisfactory surgical outcomes defined as postoperative margin reflex distance-1 (MRD1)≥3 mm in each eye and difference in MRD1≤1 mm between eyes at 6 months after levator resection. We investigated whether the degree of intraoperative lagophthalmos measured by calliper correlated with the preoperative values of MRD1, levator function and age. A stepwise multiple regression analysis was performed with intraoperative lagophthalmos as the dependent variable. The mean intraoperative lagophthalmos was 7.4±0.9 mm (range, 6-10 mm). The intraoperative lagophthalmos was found to have a statistically significant negative correlation with preoperative MRD1 (r2 =0.55, p<0.0001) and levator function (r2 =0.53, p<0.0001), respectively. A stepwise multiple regression analysis resulted in the following regression formula: Intraoperative lagophthalmos=9.08-0.48×Preoperative MRD1 - 0.26×Levator function (r2 =0.60, p<0.0001). Intraoperative lagophthalmos in patients with satisfactory surgical outcome correlated negatively with both preoperative MRD1 and levator function and accounting for both variables resulted in a stronger correlation than either variable alone. Surgeons would be able to calculate the amount of surgical correction using this formula of intraoperative lagophthalmos, which could lead to a satisfactory surgical outcome in levator resection for congenital ptosis.

Temporalis Muscle Transfer for the Treatment of Lagophthalmos in Patients With Leprosy: Refinement in Surgical Techniques to Prevent Postoperative Ptosis.

Facial paralysis resulting from leprosy has a serious impact on the entire face especially in the areas innervated by the facial nerves. In particular, lagophthalmos in patients with leprosy causes exposure keratitis, corneal, and conjunctival dryness, which can progress to blindness and disfigurement. Recently, we conducted 4 different temporalis muscle transfer (TMT) methods over the last 4 years to reduce ptosis. The methods used included Brown-McDowell, McCord-Codner, modified Gillies-Anderson, and modified Gillies. Seventy-five TMT operations in 60 patients were performed between 2011 and 2014. The mean age was 70.1. Fifteen patients had bilateral TMT procedures. As a result, ptosis appeared in 14(18.7%) of 75 TMT procedures for 4 years. To prevent or correct this complication, the following 4 technical refinements have simplified the surgery and yield better surgical outcomes. First, an increase in the length of the temporalis muscle flap to approximately 8 cm with a parallel course to the lateral canthus will reduce oblique pull. Second, the width of the fascia sling in the upper eyelid is narrowed (3-4 mm) to reduce weight on the eyelid. Third, the fascia sling in the upper lid should not be located along the full length of the upper lid but terminate 3.5 cm medial to lateral canthal tendon and in other words, should not be tied at the medial canthal tendon to reduce tension and weight. Lastly, the fascia sling in the eyelid should be located shallow (probably in subdermal layer) and as near as possible to the lid margin to prevent any functional disturbance in levator aponeurosis.

Bupivacaine Injection for Management of Lagophthalmos Due to Long-Standing Idiopathic Facial Nerve Palsy.

To report the results of bupivacaine injection into the orbicularis oculi muscle to treat lagophthalmos in patients with long-standing Bell palsy. In this prospective interventional case series, bupivacaine, 5 ml of a 0.750% solution, was injected into the preseptal and pretarsal area of the orbicularis oculi in each of 10 patients with idiopathic peripheral facial nerve palsy. The measures of vertical eyelid apertures during open and closed eyes were made before the procedure and 1, 3, and 6 months after injection. A total of 10 eyes including 2 men and 8 women with an average age of 43 years (26-64 years) were studied. The mean amount of lagophthalmos before injection and after 6 months of follow up were 3.9 mm and 2.3 mm, respectively (p = 0.01)). The mean amount of corneal exposure before injection and after 6 months of follow up was 1.05 mm and 0.25 mm, respectively (p < 0.01). The mean scleral show in open eyes before injection and after 6 months of follow up were 1.20 mm and 0.75 mm, respectively (p = 0.08). The mean scleral show in closed eyes before injection and after 6 months of follow up were 1.95 mm and 1.15 mm, respectively (p = 0.01). All the patients reported significant decrease in epiphora. Bupivacaine injection in the paretic orbicularis oculi muscle improves eyelid closure and lagophthalmos and epiphora.

Clinical observation of palpebral spring placement for lagophthalmos secondary to facial nerve palsy

Background The dysfunction of the blink reflex the eyelid-closure ability appears in the patients with facial paralysis,and its management is the implantation of mechanical-assisted eye-closure device in the upper eyelid.A novel device is palpebral spring implant.However,there is no similar study in China.Objective This study was to evaluate the clinical efficacy of palpebral spring placement for lagophthalmos caused by facial nerve palsy.Methods This clinical research complied with Helsinki declaration and the protocol was approved by Ethic Committee of Henan Eye Institute & Henan Eye Hospital.Written informed consent was obtained from each patient prior to the surgery.A retrospective serial case-observational study was performed.The medical records of 11 patients who underwent palpebral spring placement for hypophasis due to facial nerve palsy were reviewed at Henan Eye Hospital from August 2010 to November 2012.Palpebral spring placement was performed by the same surgeon to ensure a more even outcomes.Palpebral spring was made by nickel wire,with the diameter of 0.3 mm and implanted on tarsal plate in 11 eyes of 11 patients with symptomatic facial nerve palsy.The lower tip of Levine spring was encased into a small terylene bag and sutured to the anterior tarsal surface during the surgery.Preoperative and postoperative symptoms,upper eyelid margin to mid pupil distance (ULMD),degree of lagophthalmos and eyelid moving scope were examined and compared between before and after operation.The operating complication was followed-up for 8-38 months.Results The discomforted symptoms disappeared in all the operated eyes.The ULMD was (3.51±0.73) mm in preoperation and (3.20±0.86) mm in posteration,without significant difference between them (t=1.36,P=0.10).The degree of lagophthalmos was (5.94±1.57) mm and (1.06±0.98) mm in preoperation and postoperation respectively,showing a significant difference between them (t =9.42,P =0.00).The eyelid moving scope was (5.89±0.70) mm in postoperation,which was significantly increased in comparison with (0.11 ±0.33) mm of preoperation (t =22.97,P =0.00).The palpebral spring implant was regulated in 1 patient during the follow-up duration due to the trauma.No complication in other 10 patients appeared during the follow-up duration,such as implant exposure,metal fatigue or infection.Conclusions Palpebral spring placement is safe and effective for lagophthalmos in patients with facial nerve palsy.

Effect of Brow Lifting Using Botulinum A Toxin on Upper Eyelid Height in Patients With Ptosis Undergoing the Frontal Sling Technique

In this study, brow lifting with botulinum A toxin was performed on patients whose ptosis was corrected using the frontal sling technique, and the effects of this application on ptosis were investigated. Seven patients (with 12 eyelids) on whom the frontal sling procedure was performed using a tensor fascia lata graft were enrolled in the study. The patients underwent brow lifting using botulinum A toxin. Digital photographs of the patients were obtained before and 21 days after botulinum A injection. In digital imaging analysis, although a statistically significant elevation was detected in the eyelids and brows of the patients following botulinum A injection, it did not to lead to a significant difference in the degree of lagophthalmos. In the current study, this procedure was found to reduce the degree of ptosis without increasing the degree of lagophthalmos in patients who had previously undergone ptosis correction using the frontal sling.

Severe Keratopathy in Patients With AIDS With Undiagnosed Lagophthalmos

To report 2 cases of severe keratopathy in patients with AIDS with delayed diagnosis of lagophthalmos. Observational case report. The first patient presented with a corneal abscess attributed to old trauma. He responded poorly to topical treatment and suffered corneal penetration. Penetrating keratoplasty was performed, but persistent epithelial defects appeared. Finally, occult lagophthalmos was discovered. Topical ocular lubrication, eye occlusion, and lateral tarsorrhaphy were insufficient, and the graft became conjunctivalized. The second patient had corneal opacity and severe pannus in his right eye and mild punctate keratopathy in his left eye. The left cornea worsened despite treatment with lubricants. In an examination 2 weeks later, we detected a subtle lagophthalmos, which was complicated by upper eyelid retraction in the right eye. A bilateral upper blepharotomy improved the keratopathy. Patients with AIDS with severe weight loss can present with lagophthalmos because of adipose and muscular atrophy in the so-called wasting syndrome. Lagophthalmos in patients with AIDS can be difficult to detect. Clinically significant lagophthalmos is associated with ocular surface lesions in patients with AIDS with wasting syndrome.

The orbicularis oculi muscle flap: Its use for treatment of lagophthalmos and a review of its use for other applications

The management of lagophthalmos in patients with long-standing facial palsy is difficult, since the immobility and scleral show have to be corrected to protect the vision. In this article, the authors describe the treatment of paralytic eye with a static technique using a medially based orbicularis oculi muscle flap (OOMF) from the upper eyelid in patients with lagophthalmos. From April 2006 to May 2008, five Caucasian patients with ages ranging from 45 to 71 years (mean, 61 years) were treated at the Plastic Surgery Unit of Messina University. All patients underwent orbicularis oculi muscle (OOM) transposition flap to support the lower orbicularis oculi and create a suspension of the eyelid. To validate the anatomical features of the OOM transposition flap, four fresh cadaver heads (eight eyelids) were dissected to demonstrate flap viability, feasibility and suspension effect. We achieved resolution of the lagophthalmos and good cosmetic appearance in all cases. The distance between the upper and lower eyelid points during eye closing (as for sleep) was reduced postoperatively on the paralysed side compared to the contralateral healthy side. Follow-up time ranged from 3 to 25 months (mean, 12 months). All patients healed well with no complications of the flaps. There was no flap contraction, recurrent deformity or significant donor-site morbidity in the follow-up period. The incision scars were almost invisible. The authors believe that the switching of upper blepharoplasty technique from the upper eyelid to the paralysed and scarred lower lid can be used as a tool to treat lagophthalmos.

A New Technique for the Treatment of Lagophthalmos in Patients with Stabilized Exophthalmos in Graves-Basedow Disease

Surgical management of lagophthalmos in patients with facial palsy

Purpose: A prospective before-and-after trial was designed to evaluate the role of upper-lid gold weight implantation and lower lid lateral canthoplasty in the management of patients with paralytic lagophthalmos. Patients and Methods: The study included 40 patients (age range 19 to 72, mean age 46.8), and gold weights varying from 0.6 to 1.6 g were implanted in all 40 patients. Lateral canthoplasty was performed in 14 of the patients who suffered from variable degrees of lower lid laxity. Mean follow-up period was 15.7 months (range 9 to 38). Results: Complete correction of lagophthalmos and/or ectropion with resolution of preoperative symptoms was achieved in 37 of 40 patients (92.5%), and spontaneous extrusion of the gold weight occurred in only one patient (2.5%). Conclusion: Excellent results were achieved in the management of paralytic lagophthalmos with upper-lid gold weight insertion, and simultaneous lateral canthoplasty proved to be very helpful in patients with significant hypotonia of lower lid.

Gold Eyelid Weights in Patients with Facial Palsy

Lid loading with gold weights inserted into a submuscular pocket in the upper eyelid is a useful, simple, and effective method for the treatment of lagophthalmos in patients with temporary or permanent facial nerve palsy. The incidence of complications in our series was high. The reason for this are discussed, and methods of reducing the rate of complications are suggested.
