Patient Education for Endoscopic Sinus Surgery: Preliminary Experience Using 3D-Printed Clinical Imaging Data

In recent years, advances in medical imaging and three-dimensional (3D) additive manufacturing techniques have increased the use of 3D-printed anatomical models for surgical planning, device design and testing, customization of prostheses, and medical education. Using 3D-printing technology, we generated patient-specific models of mitral valves from their pre-operative cardiac imaging data and utilized these custom models to educate patients about their anatomy, disease, and treatment. Clinical 3D transthoracic and transesophageal echocardiography images were acquired from patients referred for mitral valve repair surgery and segmented using 3D modeling software. Patient-specific mitral valves were 3D-printed using a flexible polymer material to mimic the precise geometry and tissue texture of the relevant anatomy. 3D models were presented to patients at their pre-operative clinic visit and patient education was performed using either the 3D model or the standard anatomic illustrations. Afterward, patients completed questionnaires assessing knowledge and satisfaction. Responses were calculated based on a 1–5 Likert scale and analyzed using a nonparametric Mann–Whitney test. Twelve patients were presented with a patient-specific 3D-printed mitral valve model in addition to standard education materials and twelve patients were presented with only standard educational materials. The mean survey scores were 64.2 (±1.7) and 60.1 (±5.9), respectively (p = 0.008). The use of patient-specific anatomical models positively impacts patient education and satisfaction, and is a feasible method to open new opportunities in precision medicine.

Abstract 3D-printing paves the way for personalized drug therapy via implants individualized for the patient specific anatomy in chronic paranasal sinus diseases. This study brings together the workflow of modeling, manufacturing, and sterilization of 3D-printed individualized frontal neo-ostium implants (FOI) for optimization of Endoscopic Sinus Surgery (ESS) and validates the implantability of the printed devices. The study sample consisted of six adult human cadavers. Digital volume tomography (DVT) images were taken before and after ESS. The FOI models were based on the post-ESS anatomy. The area to be implanted was analysed in the preand post-ESS DVT images for volume and surface area. A specialized surgeon in rhinology judged the implantability of the 3D-printed FOI. The mean values of volume and surface area tended to be larger in the post-operation situs than in preoperation DVT images and we are therefore not yet convinced that pre-operation images will reflect the correct anatomy for the personalization of the FOI. The workflow of manufacturing and implantation of individualized 3D-printed sterile FOI is established but future studies are needed for further improvement.

Objective: Traditionally, cadaveric courses have been an important tool in surgical education for Functional Endoscopic Sinus Surgery (FESS). The recent COVID-19 pandemic, however, has had a significant global impact on such courses due to its travel restrictions, social distancing regulations, and infection risk. Here, we report the world-first remote (Functional Endoscopic Sinus Surgery) FESS training course between Japan and Australia, utilizing novel 3D-printed sinus models. We examined the feasibility and educational effect of the course conducted entirely remotely with encrypted telemedicine software.Methods: Three otolaryngologists in Hokkaido, Japan, were trained to perform frontal sinus dissections on novel 3D sinus models of increasing difficulty, by two rhinologists located in Adelaide, South Australia. The advanced manufactured sinus models were 3D printed from the Computed tomography (CT) scans of patients with chronic rhinosinusitis. Using Zoom and the Quintree telemedicine platform, the surgeons in Adelaide first lectured the Japanese surgeons on the Building Block Concept for a three Dimensional understanding of the frontal recess. They in real time directly supervised the surgeons as they planned and then performed the frontal sinus dissections. The Japanese surgeons were asked to complete a questionnaire pertaining to their experience and the time taken to perform the frontal dissection was recorded. The course was streamed to over 200 otolaryngologists worldwide.Results: All dissectors completed five frontal sinusotomies. The time to identify the frontal sinus drainage pathway (FSDP) significantly reduced from 1,292 ± 672 to 321 ± 267 s (p = 0.02), despite an increase in the difficulty of the frontal recess anatomy. Image analysis revealed the volume of FSDP was improved (2.36 ± 0.00 to 9.70 ± 1.49 ml, p = 0.014). Questionnaires showed the course's general benefit was 95.47 ± 5.13 in dissectors and 89.24 ± 15.75 in audiences.Conclusion: The combination of telemedicine software, web-conferencing technology, standardized 3D sinus models, and expert supervision, provides excellent training outcomes for surgeons in circumstances when classical surgical workshops cannot be realized.

Call Volume

Objective Perioperative patient education improves patient satisfaction, surgical outcomes, and can reduce postoperative call volume. Here, we investigate whether the use of standardized preoperative phone calls elicits similar results in patients undergoing endoscopic sinus surgery (ESS). Methods Patients undergoing ESS at a tertiary rhinology center were identified prospectively through the electronic medical record (EMR). In the intervention cohort, a standardized preoperative educational phone call was performed. A postoperative survey was utilized to collect self-assessment of satisfaction and understanding in all patients. Postoperative call rates were obtained from the EMR. Wilcoxon rank sum and chi-squared analyses were conducted to compare results. Demographics of the otology and rhinology cohorts were compared with a Mann Whitney U-test. Results Data from 43 cases and 58 controls were collected. Patients receiving the intervention were similar to controls with regard to patient-reported understanding (case:9.1 ± 1.1 vs control:9.0 ± 1.4, p = 0.801) and satisfaction (case:9.4 ± 1.1 vs 8.9 ± 1.4, p = 0.155). Both cases and controls called the clinic regarding surgical outcomes more often than for postoperative medications or administrative concerns. Independent of receiving the intervention, patients that did not call clinic postoperatively had significantly better understanding of their procedures (call:8.6 ± 1.6 vs no-call:9.5 ± 1.0, p < 0.015) and satisfaction with their experience (call:8.8 ± 1.4 vs no-call:9.5 ± 1.1, p < 0.028). Patient age may contribute to lack of impact in the rhinology cohort, as compared to the otology group, but socioeconomic status does not seem to differentiate the two samples. Conclusion Though shown in other settings, a significant impact of educational phone calls prior to surgery was not observed in this sample. Patient education calls prior to endoscopic sinus surgery were not associated with changes in postoperative call volume to the clinic. Patient understanding and satisfaction may be related to other factors, such as patient selection or demographics. Future studies may target such patients prior to ESS.
