We used calibrated 2D images uploaded by patients to an online platform to generate a 3D digital model of the limb. This was used to 3D print a splint. This method of 3D printing of splints was used for two patients who were not able to visit the hospital in person due to restrictions placed by the COVID-19 pandemic. Both patients were satisfied with the splint. We feel that this technology could be used to offer additional options to conventional splinting that allows contactless splint fitting. Level of Evidence: Level V (Therapeutic).

PURPOSE: To report outcomes of tape splint tarsorrhaphy (TST) for persistent corneal epithelial defects (PCED). DESIGN: Retrospective, interventional case series. METHODS: The study population was consecutive patients with a PCED (14 days or longer) treated at a tertiary cornea clinic with TST. Patients with a corneal epithelial defect that did not respond to treatment with a bandage contact lens were included. Patients with a follow-up time of less than 3 months were excluded. Time to PCED resolution was the main outcome measure. RESULTS: Thirty-four eyes of 33 patients (mean age 62.9 ± 17.8 years; range, 27-90 years) were included in this study. The main etiologies of the PCED were post keratoplasty (n = 15), herpes simplex virus (n = 4), superficial keratectomy (n = 3), neurotrophic cornea (n = 4), fungal keratitis (n = 2), exposure keratopathy (n = 2), failed graft (n = 1), peripheral ulcerative keratitis (n = 1), rosacea (n = 1), and stitch abscess (n = 1). Mean ± SD time from PCED presentation to TST was 58.9 ± 106.3 days (range, 14-390 days). The mean ± SD area of the PCED was 25.1 ± 15.7 mm2 (range, 0.50-42.0 mm2). After TST, resolution of the PCED was achieved in 29/34 eyes (85.3%) without the need for additional interventions within 22.5 ± 24.3 days (range, 2-105 days). The mean ± SD logMAR best-corrected visual acuity improved significantly from 1.11 ± 0.41 to 0.83 ± 0.70 (P = .02). There were no complications attributed to TST and 2 patients elected to discontinue due to discomfort. CONCLUSIONS: TST achieved resolution of PCEDs secondary to various etiologies in 85.3% of eyes, with significant improvement in vision demonstrated. This simple, inexpensive, noninvasive technique may be considered for patients with PCEDs.

BACKGROUND: Our aim was to measure and compare prolonged viral shedding (PVS) identified from external splints (ES) and intranasal packings (IP) for isolated nasal fracture (INF) repair in immediately cured asymptomatic vs. mildly symptomatic COVID-19 patients (AS-COVID vs. MS-COVID). METHODS: We designed a retrospective cohort study and enroled a sample of post-AS-COVID and post-MS-COVID patients, whose INF were treated at a German level 1 trauma centre. The primary predictor variable was COVID severity presurgery (AS-COVD vs. MS-COVID). The main outcome variable was PVS detected in ES/IP. Other study variables were separated into demographic, clinical, and operative. Descriptive, bi- and multivariate statistics were computed, and statistical significance was set at P≤ 0.05. RESULTS: The study sample comprised 15 INF patients (53.3% females; 46.7% post-AS-COVID) with a mean age of 42.2 ± 22.7 years (range, 18-85). 13.3% ES and 53.3% IP were contaminated with SARS-CoV-2. However, only IP-contamination between the two cohorts reached statistical significance (P= 0.01; odds ratio, 0.02; 95% confidence interval, 0 to 0.47; Pearson's r= 0.73; post hoc power = 87.4%). Multiple linear regression models refuted the associations between PVS and the other parameters (i.e. age, gender, time to treatment, length of hospital stay, lengths of ES/IP placement). CONCLUSIONS: Despite a relative low sample size, our findings suggest PVS via endonasal materials removed from cured COVID-19 patients, especially those healed from MS-COVID. This PVS may trigger re-infection and surgical site infections and/or transmission to other humans, and thereby, requires further investigations.
