Purpose: Removing deep parotid lobe lesions often requires a mandibulotomy procedure which carries with it a risk of significant morbidity. A transoral approach may help mitigate against complications but is technically demanding due to limited access in an area with a close relation to the internal carotid artery.
Methods: We describe a multi-disciplinary approach with the use of intraoral ultrasound-guided wire localization of a low-grade acinic cell carcinoma located in the deep lobe of the right parotid gland.
Results: Our multi-disciplinary approach facilitated the complete removal of this deep lobe parotid lesion via a transoral approach with minimal post-operative sequelae or complications.
Conclusion: In selected cases, with appropriate expertise, this dynamic approach can potentially be used even for malignant disease to limit post-operative morbidity when managing small deep parotid lobe lesions.

Objectives: To explore the synthesis of high-quality CT (sCT) from cone-beam CT (CBCT) using PE-CycleGAN for adaptive radiotherapy (ART) for nasopharyngeal carcinoma.
Methods: A perception-enhanced CycleGAN model "PE-CycleGAN" was proposed, introducing dual-contrast discriminator loss, multi-perceptual generator loss, and improved U-Net structure. CBCT and CT data from 80 nasopharyngeal carcinoma patients were used as the training set, with 7 cases as the test set.

Background And Purpose: Deep-learning-based automatic segmentation is widely used in radiation oncology to delineate organs-at-risk. Dual-energy CT (DECT) allows the reconstruction of enhanced contrast images that could help with manual and auto-delineation. This paper presents a performance evaluation of a commercial auto-segmentation software on image series generated by a DECT.

The facial and transverse facial arteries supply blood to the superficial structures of the face. Understanding these arterial variations is essential for optimizing surgical planning and outcomes, especially in invasive facial procedures. A 78-year-old male cadaveric dissection documented variations in facial and transverse facial arteries.

Parotid surgery is generally performed with the naked eye or using surgical loupes. However, this approach has technical disadvantages. Therefore, this study aimed to compare the use of an exoscope with that of loupe for parotidectomies.

First-bite syndrome (FBS) is manifested as acute and severe pain in the parotid region occurring at the first bite of a meal. While most cases of FBS arise after surgeries involving the deep lobe of the parotid gland, chemotherapy-induced FBS is extremely rare. Some adverse effects of oxaliplatin resemble FBS, suggesting it may be under-recognized.
