Oculoplastic Management of an Eyelid Zipper Injury.

We present a case of a zipper injury to an upper eyelid in a pediatric patient. The zipper was successfully removed in the operating room by using a double-action bone cutter to cut the median footplate of the zipper and release the entrapped tissue. Zipper injuries are well-described in urology literature, however, limited case reports exist in ophthalmology literature. We review several methods for zipper removal and present special considerations for eyelid injuries.

Pediatric orbital fractures.

PURPOSE OF REVIEW: The aim of this study was to summarize current evidence on the clinical presentation, evaluation, and management of pediatric orbital fractures. Recent trends in management strategies as well as emerging surgical techniques for pediatric orbital fracture repair are presented. RECENT FINDINGS: Although somewhat limited, growing bodies of evidence support a conservative approach with close follow up in pediatric orbital fractures. For those patients necessitating surgical repair, resorbable implants are increasingly preferred given their lack of donor site morbidity and a minimal impact on the developing craniofacial skeleton. There are emerging data reporting the use of three-dimensional (3D) printing-assisted approaches and intraoperative navigation; however, more research is needed to assess their applicability in the pediatric population. SUMMARY: There are few studies with large patient cohorts and long-term follow up given the rare incidence of pediatric orbital fractures, which restricts the generalizability of research on the topic. The studies available increasingly suggest that fractures without clinical evidence of entrapment can be managed conservatively with close follow up. A variety of reconstructive implants are available for those fractures necessitating repair. Donor site morbidity, availability, and need for additional procedures should all be factored into the reconstructive decision-making process.

Bilateral Congenital Nasolacrimal Duct Obstruction in Williams-Beuren Syndrome.

A 23-year-old patient with Williams-Beuren syndrome presented with ocular irritation and bilateral persistent tearing. Despite probing as an infant which showed bilateral nasolacrimal duct obstruction, dacryocystorhinostomy had been avoided due to the patient's syndromic supravalvular stenosis and related anesthesia risk. As the known diminished production of elastin in Williams-Beuren syndrome causes an array of associated vascular diseases, this case report hypothesizes that the lacrimal duct becomes obstructed through a similar mechanism. This case presents the unique findings of bilateral congenital nasolacrimal duct stenosis in a Williams-Beuren syndrome patient.

Characteristics of Orbital Injuries Associated with Maxillofacial Trauma.

INTRODUCTION: The incidence of ocular injury associated with maxillofacial trauma remains poorly defined, with reported rates ranging from 0.8% to 92%. Our study aims to more accurately characterize ocular injuries associated with midface fractures. METHODS: We performed a retrospective review of 1677 patients from 2015 to 2020 with midface fractures at a Level I trauma center. Isolated nasal bone and frontal process of the maxilla fractures were excluded. Demographic information, mechanism of injury, need for surgery, and ophthalmologic findings were documented. Statistical analysis was conducted using SPSS. RESULTS: 773 patients between the ages of 15 and 92 were identified. Trauma most commonly resulted from assault (63.8%). The association between the mechanism of injury and ocular injury was statistically significant (p = 0.003), with 78.6% of gunshot wounds and 44.3% of assault patients having an ocular injury. The Ophthalmology service evaluated 62.6% of cases preoperatively. Minor ocular injury occurred in 36% of patients, including 46.1% of isolated orbital floor, and 28.2% of zygomaticomaxillary complex fractures. Major ocular injury occurred in 10.5% of patients. CONCLUSIONS: Over 10% of patients with midface fractures were found to have major ocular injuries. Ophthalmologic exams should be performed for all patients with midface fractures to guide clinical decision making and prevent further intraoperative ocular insults. LEVEL OF EVIDENCE: Level 4. This study represents a retrospective cohort study analyzing ocular injuries detected in patients presenting to a Level I trauma center with maxillofacial fractures between 2015 and 2020 Laryngoscope, 133:1624-1629, 2023.

Epidemiologic Differences and Management of Eyelid Lesions in the Pediatric Population.

PURPOSE: To report the relative incidence of excised pediatric eyelid lesions and describe the correlation between the clinical and pathology diagnosis. METHODS: This was a retrospective analysis of 137 consecutive pathology-confirmed eyelid lesions excised at a U.S. quaternary children's hospital system. Chalazion was excluded from this study. RESULTS: Benign non-cystic epithelial lesions comprised 48.2% of all excised lesions, followed by mesenchymal (14.6%) and cystic (10.2%) lesions. The most common lesions were molluscum contagiosum (21.9%) and verruca vulgaris (19.0%). Hispanic White race represented 62.0% of cases, followed by non-Hispanic White (23.3%) and Black (8.8%). There were no malignant lesions. A specific preoperative clinical diagnosis was attempted in 70.1% of cases. Of these, 60.4% had a matching histopathology. CONCLUSIONS: The authors report a higher proportion of molluscum contagiosum and verruca vulgaris when compared to the literature; these differences may suggest geographic variance, management preference, or a general increase in incidence. Correlation with pathology showed the clinical diagnosis of eyelid lesions can be challenging even for ophthalmologists. However, malignancy in pediatric eyelid lesions is rare and submission for histopathology may be safely omitted, except in cases with atypical features or suspicion for syndromic disease. The decision for surgery should be methodically approached and take into consideration the most likely diagnosis, natural history of the disease, sociopsychological impact, anesthesia risk, and resource burden.

Standardized documentation and synoptic reporting of complex intestinal anatomy in enteric fistulation and intestinal failure.

AIM: In intestinal failure, delineation of both structure and function are key to controlling symptoms and planning further intervention. We have developed a template for developing an 'anatomy at a glance' patient-specific map to aid decision making and counselling. METHOD: A core dataset was developed and used to create an editable template to demonstrate the gastrointestinal tract, its relationship to the genitourinary tract, and specific anterior abdominal wall features. This was then used to create an anatomical template, specific to each patient, and stored in the electronic patient record and imaging archive. RESULTS: We have developed a technique for integration of multi-modal information into one diagram, easily referenced by the multidisciplinary team. Radiology, endoscopy and previous operation notes can be used to fill out a core dataset, which is then transposed into a standardized template. A worked example is shown. CONCLUSION: The mapping template has been successfully integrated into practice and aided decision making at all stages of the patient's therapeutic journey. It has been found helpful in planning routes of nutrition, preoperative optimization, surgical planning, interpreting postoperative imaging and managing patient expectations.

Pilot Trial of Neuromuscular Stimulation in Human Subjects with Chronic Venous Disease.

INTRODUCTION: Neuromuscular stimulation (NMES) has been shown to improve peripheral blood flow in healthy people. We investigated the effect of bilateral leg NMES on the symptoms of chronic venous disease. METHODS: Forty subjects were recruited from four groups: healthy, superficial insufficiency, deep insufficiency, and deep obstruction. Haemodynamic venous measurements were taken from the right femoral vein with ultrasound, laser Doppler fluximetry from the left hand and foot. Devices were then worn for 4-6 hours per day, for 6 weeks. Haemodynamic measurements were repeated at week 6. Quality of life questionnaires were taken at week 0, 6 and 8. RESULTS: The mean age was 48.7, BMI 28.6kg/m2, and maximum calf circumference 39.0 cm. Twenty-four subjects were men. NMES increased femoral vein peak velocity, TAMV and volume flow by 55%, 20%, 36% at 20 minutes (all p<0.05), which was enhanced at week 6 (PV and TAMV p<0.05). Mean increases in arm and leg fluximetry were 71% and 194% (both p<0.01). Leg swelling was reduced by mean 252.7 mL (13%, p<0.05) overall; 338.9 mL (16%, p<0.05) in venous disease. For those with venous pathology, scores for disease specific and generic quality of life questionnaires improved. Those with C4-6 disease benefitted the most, with improvements in VDS score of 1, AVVQ of 6, and SF-12 of 10. CONCLUSION: NMES improves venous haemodynamic parameters in chronic venous disease, which is enhanced by regular use. NMES reduces leg oedema, improves blood supply to the skin of the foot, and may positively affect quality of life. CLINICAL TRIALS: This trial was registered with www.clinicaltrials.org.uk (NCT02137499).

Eyelid Malposition after Blepharoplasty: An Ounce of Prevention.

Upper and lower eyelid blepharoplasty are common procedures performed to provide a more youthful and rejuvenated appearance. However, this seemingly straightforward procedure may result in lid malpositions, frustrating the patient and surgeon alike, which ultimately require further treatment. We review preoperative assessment pearls to avoid these lid malpositions, as well as options for treating any postoperative complications related to lid position. Many of the techniques discussed in this article, in addition to many other oculoplastic procedures, are available to view in Dr. Richard C. Allen's operative video library at: http://webeye.ophth.uiowa.edu/eyeforum/video/plastics/ .

Topical Corticosteroid Use Associated With Increased Degree of Ptosis and Rate of Ptosis Repair Failure.

PURPOSE: To compare the degree of ptosis and the risk of ptosis repair failure among patients with and without a history of topical corticosteroid use. METHODS: Retrospective, case-controlled study examining topical corticosteroid use among adults with ptosis who underwent external levator advancement/resection (ELR) or Müller muscle conjunctival resection with at least 3 months postoperative follow-up. Comparative statistical analyses of surgical outcomes were performed amongst patients with and without history of topical corticosteroid use. RESULTS: A total of 240 patients (406 eyelids) met study criteria, of which 36 patients (44 eyelids) had history of topical corticosteroid use. Mean preoperative margin reflex distance was 0.20 mm and 0.58 mm for topical corticosteroid and non-corticosteroids users (p = 0.01). Mean preoperative levator function was 9.78 mm and 10.38 mm for topical corticosteroid and non-corticosteroid users (p = 0.02). The rate of ptosis repair failure was 30% and 16% in patients with and without a history of topical corticosteroid use (odds ratio 2.25, 95% confidence interval 1.10-4.55; p = 0.03). The rate of recurrence per surgical type in eyelids with and without history of topical corticosteroid use was: external levator advancement/resection 11/27 (41%) and 48/266 (18%) (odds ratio = 3.12, confidence interval 1.36-7.15 0; p = 0.01); Müller muscle conjunctival resection 2/17 (12%) and 9/96 (9%) (odds ratio 1.29, confidence interval 0.25-6.56; p = 0.76). CONCLUSIONS: Topical corticosteroid use is associated with more severe presenting ptosis and increased rates of ptosis repair failure. Compared to Müller muscle conjunctival resection, there is a significantly higher rate of ptosis repair failure in patients undergoing external levator advancement/resection.

Polytetrafluoroethylene frontalis suspension in blepharospasm with eyelid apraxia: an effective and well-tolerated adjunct to botulinum toxin therapy.

Purpose: To report the efficacy of polytetrafluoroethylene (PTFE) frontalis suspension for blepharospasm with eyelid apraxia and postoperative botulinum toxin requirements. Methods: Retrospective chart review of patients with blepharospasm and eyelid apraxia who underwent frontalis suspension. The primary outcome was a surgical success, defined by surgeon- and patient-reported success in postoperative eyelid opening. Comparative statistical analyses of botulinum toxin dosage and treatment intervals were performed amongst patients before and after frontalis suspension ptosis repair. Results: Five patients (10 eyelids) met the study criteria, of which 40% were female. Mean age was 63.2 years. All patients had successful surgical outcomes based on physician-reported and patient reported satisfaction with the postoperative eyelid opening. Average follow-up was 14 months. Preoperative botulinum toxin treatments averaged 80.4 units (range 32-110, SD 33.2) to the periocular region over an average of 9.6-week intervals. Postoperative botulinum toxin treatments averaged 61.4 units (range 24-110, SD 34.7) to the periocular region over an overage of 9.8-week intervals. No patients experienced postoperative exposure keratopathy, extrusion of the sling, or postoperative infection. Conclusions: Frontalis suspension using PTFE suture in the setting of blepharospasm with eyelid apraxia was found to be a safe and effective procedure. Frontalis suspension in this population is not a substitute for botulinum toxin treatment but may allow for reduced treatment dosage. Frontalis suspension appears to increase patient functionality with improved eyelid opening in patients with blepharospasm with eyelid apraxia.

Outcomes After Müller Muscle Conjunctival Resection Versus External Levator Advancement in Severe Involutional Blepharoptosis.

PURPOSE: To compare outcomes between Müller muscle conjunctival resection (MMCR) ptosis repair and external levator resection (ELR) in patients with severe involutional blepharoptosis. DESIGN: Retrospective, interventional, comparative case series. METHODS: A retrospective review was performed of patients who underwent ptosis repair between 2012 and 2019. Inclusion criteria were patients who underwent MMCR or ELR ptosis repair, patients with complete documentation of preoperative eyelid measurements, and patients with documentation of postoperative outcome. The main outcome measure was surgical failure, defined as patient-reported or physician-reported dissatisfaction with postoperative eyelid height or postoperative upper margin reflex distance (MRD1) of less than 2 mm. Severe ptosis was described as an MRD1 of 0 or worse. Outcome analysis was also performed after stratification for concomitant blepharoplasty performed at the time of ptosis repair. RESULTS: A total of 231 patients (372 eyelids) met the study criteria, of which 142 eyelids had severe ptosis. Comparing outcomes of MMCR vs ELR in patients with severe ptosis, there was a statistically significant higher rate of success after MMCR (P = .0143). The rate of ptosis repair success in eyelids that underwent MMCR was 97.2% and 90.9% in patients with severe ptosis and mild/moderate ptosis, respectively (P = .42). In eyelids that underwent ELR, the rate of ptosis repair success was 77.4% and 85% in eyelids with severe ptosis and mild/moderate ptosis, respectively (P = .15). Concomitant blepharoplasty did not affect ptosis repair outcomes in any group. CONCLUSIONS: MMCR ptosis repair is an effective approach in treating patients with severe ptosis, and it may offer superior outcomes to ELR. In patients with good responses to phenylephrine, MMCR may offer an efficient and highly efficacious surgery regardless of presenting MRD1.
