Computed tomography (CT) scans represent the gold standard in the planning of functional endoscopic sinus surgeries (FESS). Yet, radiologists and otolaryngologists have different perspectives on these scans. In general, residents often struggle with aspects involved in both reporting and operation planning. The aim of this study was to compare the completeness of structured reports (SR) of preoperative CT images and structured operation planning (SOP) to conventional reports (CR) and conventional operation planning (COP) to potentially improve future treatment decisions on an individual level. In total, 30 preoperative CT scans obtained for surgical planning of patients scheduled for FESS were evaluated using SR and CR by radiology residents. Subsequently, otolaryngology residents performed a COP using free texts and a SOP using a specific template. All radiology reports and operation plannings were evaluated by two experienced FESS surgeons regarding their completeness for surgical planning. User satisfaction of otolaryngology residents was assessed by using visual analogue scales. Overall radiology report completeness was significantly higher using SRs regarding surgically important structures compared to CRs (84.4 vs. 22.0%, p<0.001). SOPs produced significantly higher completeness ratings (97% vs. 39.4%, p<0.001) regarding pathologies and anatomical variances. Moreover, time efficiency was not significantly impaired by implementation of SR (148 s vs. 160 s, p = 0.61) and user satisfaction was significantly higher for SOP (VAS 8.1 vs. 4.1, p<0.001). Implementation of SR and SOP results in a significantly increased completeness of radiology reports and operation planning for FESS. Consequently, the combination of both facilitates surgical planning and may decrease potential risks during FESS.

Level Of Agreement

We conducted a study to determine the level of agreement among five surgeons who assessed the surgical risk to key neighboring structures prior to endoscopic sinus surgery as depicted on coronal computed tomography (CT). The five observers studied preoperative CT scans that had been performed on 29 patients. Two scoring systems were used to rate each scan: the Lund-Mackay system and our own risk-assessment system. Kappa analysis was used to measure interobserver agreement. We found that the overall level of agreement among the five surgeons according to the Lund-Mackay criteria was moderate, while agreement according to our risk-assessment system was only slight. We conclude that surgeons agreement on the bony detail of risk structures is not as strong as our agreement on other factors, such as staging disease.

Objective To determine if the introduction of a systematic preoperative sinus computed tomography (CT) checklist improves identification of critical anatomic variations in sinus anatomy among patients undergoing endoscopic sinus surgery. Study Design Single-blinded prospective cohort study. Setting Tertiary care hospital. Subjects and Methods Otolaryngology residents were asked to identify critical surgical sinus anatomy on preoperative CT scans before and after introduction of a systematic approach to reviewing sinus CT scans. The percentage of correctly identified structures was documented and compared with a 2-sample t test. Results A total of 57 scans were reviewed: 28 preimplementation and 29 postimplementation. Implementation of the sinus CT checklist improved identification of critical sinus anatomy from 24% to 84% correct ( P < .001). All residents, junior and senior, demonstrated significant improvement in identification of sinus anatomic variants, including those not directly included in the systematic review implemented. Conclusion The implementation of a preoperative endoscopic sinus surgery radiographic checklist improves identification of critical anatomic sinus variations in a training population.

The Face

In reconstructive craniofacial surgery, the bilateral symmetry of the midplane of the facial skeleton plays an important role in surgical planning. Surgeons can take advantage of the intact side of the face as a template for the malformed side by accurately locating the midplane to assist in the preparation of the surgical procedure. However, despite its importance, the location of the midline is still a subjective procedure. The aim of this study was to present a 3D technique using a convolutional neural network and geometric moments to automatically calculate the craniofacial midline symmetry of the facial skeleton from CT scans. To perform this task, a total of 195 skull images were assessed to validate the proposed technique. In the symmetry planes, the technique was found to be reliable and provided good accuracy. However, further investigations to improve the results of asymmetric images may be carried out.

This conclusion to the special issue highlights the role of scholars in advancing the public discussion about forced migration. As countries around the world are adopting increasing restrictions on the entry of refugees, academic research can help to dispel some of the myths and apprehensions regarding the risks that forced migration entails. While refugees may be linked to conflict and violence in limited circumstances, the research generally demonstrates that robust international cooperation to manage refugee settlements, provide adequate humanitarian assistance, and integrate refugees into host communities, among other policies, can help to mitigate potential risks. Directions for future research and analysis are also discussed. Forced migration scholars should endeavor to collect more individual-level data; seek to understand factors that exacerbate or reduce security risks associated with cross-border militancy; conduct research on the long-term integration of refugees; and seek to understand the causes and consequences of resettlement and repatriation policies.

Objectives: To examine the frequency in which angled endoscopes are necessary to visualize the true maxillary ostium (TMO) following uncinectomy and prior to maxillary antrostomy. Additionally, to identify preoperative computed tomography (CT) measures that predict need for an angled endoscope to visualize the TMO. Study Design: Retrospective study. Setting: Tertiary academic hospital. Patients and Methods: Patients who underwent endoscopic sinus surgery (ESS) between December of 2017 and August of 2018 were retrospectively identified. Cases were reviewed if they were primary ESS cases for chronic rhinosinusitis without polyposis and if they were at least 18 years of age. Results: Sixty-three maxillary antrostomies were reviewed (82.5% were from bilateral cases). Thirty-five cases (55.6%) required an angled endoscope in order to visualize the TMO. Of the preoperative CT measures examined, a smaller sphenoid keel-caudal septum-nasolacrimal duct (SK-CS-NL) angle was significantly associated with need for an angled endoscope intraoperatively to visualize the TMO (17.1° SD ± 3.2 vs 15.0° SD ± 2.9; P = .010). Conclusion: Angled endoscopes are likely required in the majority of maxillary antrostomies to visualize the TMO. This is important to recognize in order to prevent iatrogenic recirculation. The SK-CS-NL angle may help to identify cases preoperatively which require an angled endoscope to identify the TMO during surgery.

The Relationship

Objective: The agger nasi cell (ANC) is an easily identifiable landmark when approaching the frontal sinus. The success of endoscopic frontal sinus surgery may be influenced by the width of the frontal recess (FR). The aim of this study is to examine the relationship between the FR width and the ANC size in Japanese patients. In addition, the effect of various frontal recess cells (FRCs) on the development of frontal sinusitis has been examined. Materials and methods: Multiplanar computed tomography (CT) scans of the nasal cavities and paranasal sinuses in 95 patients (190 sides) before endoscopic sinus surgery were reviewed. The presence of FRCs, the thickness of the frontal beak (FB), the ANC size, and the anterior-to-posterior (A-P) length of the frontal isthmus (FI) and FR were evaluated in patients with and without frontal sinusitis. Results: The prevalence of the ANC, frontal cell types 1, 2, 3, and 4, frontal bullar cell (FBC), suprabullar cell, supraorbital ethmoid cell, and interfrontal sinus septal cell was 85.3%, 11.6%, 0%, 7.9%, 0%, 25.3%, 45.8%, 16.8%, and 15.3%, respectively. The ANC volume showed a significant positive correlation with the A-P length of the FI and FR. The incidence of frontal sinusitis in the patients with FBCs was significantly higher than that without FBCs. Conclusion: A large ANC offers a greater potential to facilitating the approach to the frontal sinus because of the extensiveness of the FR in Japanese patients. The presence of FBCs may be related to a higher incidence of frontal sinusitis.

Background The aim of this study was to report objective and subjective outcomes after revision sinus surgery (RESS) for chronic rhinosinusitis (CRS). Methods We performed a retrospective analysis of prospectively collected data in 125 patients requiring revision functional endoscopic sinus surgery after failing both maximum medical therapy and prior sinus surgery for CRS. Patients were seen and treated over a 3-year period (1999–2001) in a tertiary rhinology setting. Computed tomography (CT) scans were graded as per Lund-MacKay and patient symptom scores were recorded using the Sinonasal Outcome Test 20 (SNOT-20) instrument. Individual rhinosinusitis symptoms were evaluated on a visual analog scale (0–10) before and after surgery. All patients had a minimum 2-year follow-up. Results The mean number of prior sinus procedures was 1.9 ± 0.1 (range, 1–7) and the mean preoperative CT grade was 13.4 ± 0.7. Patients with asthma and polyposis had higher CT scores than those without these processes. Preoperative mean SNOT-20 and endoscopy scores were 30.7 ± 1.3 and 7.3 ± 0.4, respectively. At the 2-year follow-up, mean SNOT-20 and endoscopy scores improved to 7.7 ± 0.6 and 2.1 ± 0.4, respectively (p < 2.8 X 10-10). At 12-month follow-up, each individual symptom score decreased significantly. Overall, 10 patients failed RESS and required additional surgical intervention for an overall failure rate of 8.0%. All patients who failed RESS had nasal polyposis. Conclusion Revision functional endoscopic sinus surgery benefits patients that fail maximum medical therapy and prior sinus surgery for CRS by objective and subjective measures.
