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.

<p class="abstract">In this era of minimally invasive surgical interventions, the knowledge of the physiology and pathophysiology of the frontal sinus is vital to the endoscopic rhinologist. The conventional procedure of sinus surgery has given way to functional endoscopic sinus surgery whereby now the emphasis is not on cleaning the sinus but reverting the function of the sinus. The surgery is only done at the frontal recess only. The physiology and pathophysiology of the frontal sinus needs an introspection.</p>

AbstractObjectiveThis study aimed to determine the predictors of disease progression after functional endoscopic sinus surgery in patients with chronic rhinosinusitis.MethodA total of 281 adult chronic rhinosinusitis patients who underwent primary bilateral functional endoscopic sinus surgery between 2007 and 2017 and had at least 12 months of follow-up endoscopic evaluation were examined. Patients were divided into eosinophilic (n= 205) and non-eosinophilic chronic rhinosinusitis groups (n= 76). In order to determine adverse factors, post-operative endoscopic appearance scores were analysed in relation to the pre- and intra-operative findings using multiple regression analyses.ResultsThe post-operative course of eosinophilic cases deteriorated over time, like the early period for non-eosinophilic cases. Frontal sinus polyps recurred early in eosinophilic chronic rhinosinusitis. Multivariate analyses indicated young adulthood, asthma, high computed tomography score and frontal sinus polyps as significant adverse predictors.ConclusionEarly, appropriate estimation of sinonasal conditions appears to be crucial for successful surgical management of chronic rhinosinusitis.

Abstract Introduction: For Functional Endoscopic Sinus Surgery (FESS), the surgeon needs an accurate depiction of the anatomy of paranasal sinuses and their variations. Computed tomography (CT Scan) fulfills this requirement by providing detailed anatomy, the anatomical variants, and the extent of the disease in and around the Para nasal sinuses. The aim of this study is to show the anatomy of the Frontal sinus as delineated by the computed tomography. Materials and Methods: STUDY DESIGN: Cross section Descriptive Study. Out of 337 patients above 12 years of age who were referred for computed tomography of paranasal sinuses in the Dept. of Radio- Diagnosis, Govt. Medical College and Hospital from December 2015 till October 2017, 200 adults(males and females) were randomly selected.Of the 200 subjects studied 37(18.5%) subjects had hypoplastic/ non or poorly pneumatised frontal sinuses of which 31 (15.5%) were bilateral and 6 (3%) were unilateral i.e. on right side. Observations and results: Intra frontal cell were seen in about 64 (32%) subjects of which 26 (13%) on right side, 24 (12%) were on left side and 14 (7%) were bilateral. Extension of pneumatisation into crista galli was seen in 16 (8%) subjects and into orbital roof was seen in 6 (3%) subjects. Conclusion: The findings in this study show that anatomical variations in the Para nasal sinuses and nasal cavity are common. Computed tomography is fundamental radiologic investigation for diagnosis of the Sino nasal lesions or pre and post-surgical assessment.

Background. The frontal recess area represents a challenge to ENT surgeons due to its narrow confines and variable anatomy. Several types of cells have been described in this area. The agger nasi cells are the most constant ones. The frontal cells, originally classified by Kuhn into 4 types, have been reported in the literature to exist in 20%–41% of frontal recesses. Aim of the Study. To identify the prevalence of frontal recess cells and their relation to frontal sinus disease. Methods. Coronal and axial CT scans of paranasal sinuses of 70 patients admitted for functional endoscopic sinus surgery (FESS) were reviewed to identify the agger nasi, frontal cells, and frontal sinus disease. Data was collated for right and left sides separately. Results. Of the 140 sides reviewed, 126 (90%) had agger nasi and 110 (78.571%) had frontal cells. 37 frontal sinuses were free of mucosal disease, 48 were partly opacified, and 50 were totally opacified. There was no significant difference found in frontal sinus mucosal disease in presence or absence of frontal cells or agger nasi. Conclusions. The current study shows that frontal cells might be underreported in the literature, as the prevalence identified is noticeably higher than previous studies.

Background: Aim: To assess efficacy of functional endoscopic sinus surgery in surgical management of ethmoid polyps.Methods:One hundred twelve adult patients age ranged 18- 38 years of either gender with ethmoid polyps underwent FESS under general anesthesia. The extent of surgery was decided based on the findings in pre-operative CT scan of paranasal sinuses. Anterior ethmoidectomy, posterior ethmoidectomy, middle meatus antrostomy and clearance of frontal recess were performed in all the patients. Five functional criteria were evaluated as nasalobstruction , anosmia, rhinorrhea, post nasal drip, head ache and facial pain.Results:Pre- operative nasal obstruction percentage was 3.42 and post- operative ercentage was 2.10, Anosmia percentage was 2.14 and 1.15, Rhinorrhea percentage was 3.56 and 2.08 and ocular problem in 1 and synechia in 4 cases.Conclusions:Functional endoscopic sinus surgery found to be effective in management of ethmoid polyps and hence can be the treatment of choice.
