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.

Difficult Cases

Seven patients with frontal and ethmoid mucoceles treated by endoscopic sinus surgery were reviewed. Five cases were successfully managed, with two requiring a trephine procedure in combination with the intranasal endoscopic approach. Follow-up ranged from 3 to 33 months with a mean of 17.8 months. The use of endoscopic instruments through a trephine incision is recommended in difficult cases to assure patency of the frontal sinus recess. When a large frontal sinus mucocele extends into the anterior ethmoid, the endoscopic approach becomes ideal. Sinus mucoceles can be handled safely and successfully by endoscopic surgery and may eliminate the need for more traditional external procedures.

Treatment of frontal sinus disease represents one of the most challenging aspects of endoscopic sinus surgery. Frontal sinus mucocele drainage may be an exception to the rule because in many instances, the expansion of the mucocele widens the frontal sinus recess and renders surgical drainage technically undemanding. Recently, there has been an increased interest in in-office procedures in otolaryngology because of patient satisfaction and substantial savings of time and cost for both patients and physicians. Similarly, the past few years have witnessed an increased use of balloon dilation devices in sinus surgery. Previously, we have described the in-office use of this device in treating patients who failed prior conventional frontal sinusotomy in the operating room. In this report, we describe our step-by-step in-office experience using this tool for drainage of a large frontal sinus mucocele.

Confirming a thorough dissection of the frontal sinus during endoscopic sinus surgery can be challenging, and some surgeons would benefit from reliable topographic landmark identification to ensure completion of this sinus dissection. We defined (1) the “horizon sign” as the curvilinear shadow of the posterior table cast superiorly upon the anterior table of the frontal sinus at the acute angle of their meeting point and (2) the “frontal bar” as a sagittal septation at the union of the anterior/posterior tables. A cadaveric study, followed by an intraoperative consecutive case series, was performed to evaluate these 2 landmarks as indicators of complete dissection. The horizon sign was extremely reliable, identified in 100% of cadaveric frontal sinuses and intraoperative frontal sinuses. The frontal bar was present in only 67% of frontal sinuses by computed tomography. In live patients, the sensitivity and specificity of the frontal bar were 62% and 95%, respectively.
