The eustachian tube (E-tube) function is known to be related with sinusitis; however, the effect of endoscopic sinus surgery (ESS) on E-tube function is not clearly documented. This study aimed to prospectively evaluate the function of the E-tube by using both subjective and objective tests in adult chronic sinusitis patients undergoing ESS, and to compare with those of the patients without sinusitis. Thirty adult patients who underwent ESS for treatment of chronic sinusitis and another thirty patients without sinusitis who underwent other nasal surgeries (septoplasty, rhinoplasty, or closed reduction) were evaluated and compared for E-tube function before and after three months of their surgeries. The E-tube function tests included the seven-item eustachian tube dysfunction questionnaire (ETDQ-7), Valsalva test, and inflation-deflation test that were compared preoperatively and postoperatively in both groups. Compared with the group without sinusitis, the ESS group showed significant improvement of E-tube function after surgery in the ETDQ-7 (p = 0.002), right Valsalva test (p = 0.015), right deflation test (p = 0.005), and left deflation test (p = 0.006). A binary logistic regression analysis revealed that ESS significantly improved E-tube function in the right Valsalva test in a univariate (p = 0.021) and multivariate analysis (p = 0.008), and E-tube function in the left deflation test in a univariate (p = 0.021) and multivariate analysis (p = 0.039). These findings indicate that E-tube function is significantly improved after ESS in adult sinusitis patients, and that the presence of sinusitis and implementation of ESS should be considered (if sinusitis is present) in managing patients with ear diseases that are affected by E-tube function.

Inadequate intraoperative analgesia causes the deterioration of the condition of the surgical field (CSF) as a result of hemodynamic instability. Analgesia monitors are used to guide remifentanil) infusion to optimize intraoperative analgesia. The main aim of the current randomized controlled trial was to investigate the potential advantages of intraoperative analgesia monitoring using surgical Pleth index (SPI)- or pupillometry (PRD)-guided remifentanil administration for managing the volume of total intraoperative blood loss (TEIBL), CSF, and length of operation (LOP) in comparison with the standard practice in patients undergoing endoscopic sinus surgery (ESS). The 89 patients in our study were grouped as follows: 30 patients were assigned to the general analgesia (GA) group, 31 patients were assigned to the SPI group, and 28 patients were assigned to the PRD group. The speed of remifentanil infusion was accelerated by 50% when SPI, PRD, or BSS were increased by >15 points, >5%, or >2, respectively, in adjacent groups until their normalization. The SPI group showed significantly lower TEIBL in comparison to the GA group (165.2 ± 100.2 vs. 283.3 ± 193.5 mL; p < 0.05) and a higher mean arterial pressure (MAP; 73.9 ± 8 vs. 69.2 ± 6.8 mmHg; p < 0.05). In the PRD group, a shorter LOP compared with the GA group was observed (63.1 ± 26.7 min vs. 82.6 ± 33.1 min; p < 0.05). It was noted that the PRD group had a lower total remifentanil consumption than the SPI group (1.3 ± 1.4 vs. 1.8 ± 0.9 mg; p < 0.05). In ASA I-III patients undergoing ESS, intraoperative monitoring based on state entropy and SPI values can optimize the CSF and reduce TEIBL, whereas monitoring based on state entropy and PRD measurements can optimize the cost effectiveness of anesthetic drugs and the use of the operation room.

Background and Objectives: Preoperative planning utilizing computed tomographies (CT) is of utmost importance in functional endoscopic sinus surgery (FESS). Frequently, no uniform documentation and planning structures are available to residents in training. Consequently, overall completeness and quality of operation planning may vary greatly. The objective of the present study was to evaluate the impact of a structured operation planning (SOP) approach on the report quality and user convenience during a 4-day sinus surgery course. Materials and Methods: Fifteen participant were requested to plan a FESS procedure based on a CT scan of the paranasal sinuses that exhibited common pathological features, in a conventional manner, using a free text. Afterwards, the participants reevaluated the same scans by means of a specifically designed structured reporting template. Two experienced ENT surgeons assessed the collected conventional operation planning (COP) and SOP methods independently with regard to time requirements, overall quality, and legibility. User convenience data were collected by utilizing visual analogue scales. Results: A significantly greater time expenditure was associated with SOPs (183 s vs. 297 s, p = 0.0003). Yet, legibility (100% vs. 72%, p < 0.0001) and overall completeness (61.3% vs. 22.7%, p < 0.0001) of SOPs was significantly superior to COPs. Additionally, description of highly relevant variants in anatomy and pathologies were outlined in greater detail. User convenience data delineated a significant preference for SOPs (VAS 7.9 vs. 6.9, p = 0.0185). Conclusions: CT-based planning of FESS procedures by residents in training using a structured approach is more time-consuming while producing a superior report quality in terms of detailedness and readability. Consequently, SOP can be considered as a valuable tool in the process of preoperative evaluations, especially within residency.

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.

Abstract Background Functional Endoscopic Sinus Surgery (FESS) has been employed as a surgical intervention to treat chronic rhinosinusitis in patients with no response to drug therapy, during which the surgical vision may be greatly reduced by a small amount of bleeding. There by, the intraoperative controlled hypotension can improve the visibility. While excessive bleeding intraoperative cause serious complications in the postoperative period, including eye socket infections, visual acuity damage, meningeal infections, and other. Objective Induced hypotension limits intra operative (IO) blood loss provides better visibility of the surgical field and diminishes the incidence of major complications during Functional Endoscopic Sinus Surgery (FESS). We aimed at comparing Nitroglycerine; Magnesium Sulfate and Dexmedetomidine for inducing controlled hypotension and evaluate narcotic used, mac of inhalational anesthesia, and Ramsay Sedation Scale (RSS) in the recovery and pre-anesthetic time in patients undergoing Functional Endoscopic Sinus Surgery (FESS). Patients and Methods This study was conducted on 75 patients who underwent elective functional endoscopic sinus surgery (FESS) who matched the inclusion criteria and were randomly allocated into 3 groups each containing 25 patients. The first group received loading dose of dexmedetomidine 1μg/kg infused over 10 min before induction of anesthesia then 0.7 μg/kg/h via syringe pump, second group received nitroglycerine infusion at a dose of 2μg/kg/min according to the response started after induction, intubation, positioning and sterilization of the patient and third group received a loading dose of magnesium sulfate 40 mg/kg over 10 minutes followed by an infusion 15mg/kg/h via syringe pump. Results The result of our study showed that dexmedetomidine, magnesium sulfate, or nitroglycerine successfully induced deliberate hypotension and were effective in providing good surgical field during FESS, but dexmedetomidine showed superior hemodynamic profile. Compared with nitroglycerine, both dexmedetomidine and magnesium sulfate offered the advantage of inherent analgesic and sedative effect. Conclusion Dexmedetomidine, magnesium sulfate, or nitroglycerine successfully induced deliberate hypotension and were effective in providing good surgical field during FESS, but dexmedetomidine showed superior hemodynamic profile. Compared with nitroglycerine, both dexmedetomidine and magnesium sulfate offered the advantage of inherent analgesic and sedative effect. Dexmedetomidine also showed shorter duration of surgery with less blood loss and favorable frommer score with more surgeon satisfaction. Dexmedetomidine showed longest time to 1st analgesic rescue in PACU comparing with magnesium sulfate and nitroglycerine. So, it’s advised to use dexmedetomidine to induce hypotension than magnesium sulfate and nitroglycerine. However, dexmedetomidine should be used with caution as it caused hypotension and bradycardia, t had sedative effect with low aldert score comparing with nitroglycerine and magnesium sulfate.
