  Abstract

  The expanded endonasal approach (EEA) to resect skull base lesions has classically included the resection of one or both middle turbinates (MT). Here, we describe for the first time a technique that spares the MT entitled middle turbinate release with preservation (MTRP) that can give an alternative and feasible approach to skull base surgeons that wish to maintain this endonasal landmark.

  Abstract

  A wearable headband treats nasal congestion using acoustic resonance and AI-estimated anatomy. Individuals with higher nasal depth-to-height ratio used acoustic therapy more often. Depth-to-height ratio may be an anatomical marker for increased nasal congestion risk.

  Abstract

  In benign tumors with potential for malignant transformation, sampling error during pre-operative biopsy can significantly change patient counseling and surgical planning. Sinonasal inverted papilloma (IP) is the most common benign soft tissue tumor of the sinuses, yet it can undergo malignant transformation to squamous cell carcinoma (IP-SCC), for which the planned surgery could be drastically different. Artificial intelligence (AI) could potentially help with this diagnostic challenge.CT images from 19 institutions were used to train the Google Cloud Vertex AI platform to distinguish between IP and IP-SCC. The model was evaluated on a holdout test dataset of images from patients whose data were not used for training or validation. Performance metrics of area under the curve (AUC), sensitivity, specificity, accuracy, and F1 were used to assess the model.Here we show CT image data from 958 patients and 41099 individual images that were labeled to train and validate the deep learning image classification model. The model demonstrated a 95.8 % sensitivity in correctly identifying IP-SCC cases from IP, while specificity was robust at 99.7 %. Overall, the model achieved an accuracy of 99.1%.A deep automated machine learning model, created from a publicly available artificial intelligence tool, using pre-operative CT imaging alone, identified malignant transformation of inverted papilloma with excellent accuracy.

• Machine learning of endoscopy images to identify, classify, and segment sinonasal masses. International forum of allergy & rhinology Levi, L., Ye, K., Fieux, M., Renteria, A., Lin, S., Xing, L., Ayoub, N. F., Patel, Z. M., Nayak, J. V., Hwang, P. H., Chang, M. T. 2025

  Abstract

  We developed and assessed the performance of a machine learning model (MLM) to identify, classify, and segment sinonasal masses based on endoscopic appearance.A convolutional neural network-based model was constructed from nasal endoscopy images from patients evaluated at an otolaryngology center between 2013 and 2024. Images were classified into four groups: normal endoscopy, nasal polyps, benign, and malignant tumors. Polyps and tumors were confirmed with histopathological diagnosis. Images were annotated by an otolaryngologist and independently verified by two other otolaryngologists. We used high- and low-quality images to mirror real-world conditions. The models used for classification (EfficientNet-B2) and segmentation (nnUNet) were trained, validated, and tested at an 8:1:1 ratio. The performance accuracy was averaged across a 10-fold cross-validation assessment. Segmentation accuracy was assessed via Dice similarity coefficients.A total of 1242 images from 311 patients were used. The MLM was trained, validated, and tested on 663 normal, 276 polyps, 157 benign, and 146 malignant tumors images. Overall, the model performed at 84.1 ± 4.3% accuracy in the validation set and 80.4 ± 1.7% in the test set. The model correctly identified the presence of a sinonasal mass at 90.5 ± 1.2% accuracy rate. The MLM accuracy performance rates were 86.2 ± 1.0% for polyps and 84.1 ± 1.8% for tumors. Benign and malignant tumor subclassification achieved 87.8 ± 2.1% and 94.0 ± 2.4% accuracy, respectively. Segmentation accuracies for polyps were 72.3% and 72.8% for tumors.An MLM for nasal endoscopy images can perform with moderate to high accuracy in identifying, classifying, and segmenting sinonasal masses. Performance in future iterations may improve with larger and more diverse training datasets.

• Stepwise Empty Nose Syndrome Evaluation (SENSE) test-A modified cotton test for reduced bias in office diagnosis of empty nose syndrome. International forum of allergy & rhinology Levi, L., Yang, A., Tsai, E. F., Ma, Y., Ibrahim, N., Dholakia, S. S., Rao, V. K., Renteria, A., Cao, X., Chang, M. T., Nayak, J. V. 2024

  Abstract

  Diagnosis of empty nose syndrome (ENS) relies on the ENS six-item questionnaire (ENS6Q) with a score of ≥11, followed by a "positive" cotton test yielding seven-point reduction from baseline ENS6Q score via cotton placement to the inferior meatus (IM). Given the intricacies of diagnosing ENS and the propensity for false positives with the standard cotton test, we modified the classic single-step cotton test into a four-part Stepwise Empty Nose Syndrome Evaluation (SENSE) cotton test to reduce bias and evaluate the placebo effect.Individuals diagnosed with ENS underwent the SENSE test, a single-blinded, four-step, office-based cotton test, without topical anesthesia or decongestants. Conditions included: (1) placebo/no cotton placed; (2) complete cotton-blockade of nasal vestibule; (3) cotton placed medially against the nasal septum; and (4) cotton placed laterally in the IM (site of inferior turbinate tissue loss). With each condition, patients completed an ENS6Q.Forty-eight ENS patients were included. Twenty-nine percent demonstrated a placebo effect (p < 0.001), 40.4% had a positive response to complete cotton-blockade (p < 0.001), 64.4% to septum-placed cotton, and 79.1% to IM-placed cotton (p < 0.001), corresponding to a mean ENS6Q reduction of 11.9 points (p < 0.001). Notably, the mean difference in ENS6Q scores between septum and IM placement was 1.7 (p < 0.001).The SENSE test offers further insight into subtleties of nasal breathing experienced by ENS patients. The placebo effect can be prominent and important to consider with individual patients. While most ENS patients prefer any intranasal cotton placement over baseline, blinded testing reveals these patients can accurately discriminate minimal changes in nasal aerodynamics.
