Unsupervised Cross-Modality Domain Adaptation for Segmenting Vestibular Schwannoma and Cochlea with Data Augmentation and Model Ensemble [PDF]

arXiv, 2021
Magnetic resonance images (MRIs) are widely used to quantify vestibular schwannoma and the cochlea. Recently, deep learning methods have shown state-of-the-art performance for segmenting these structures. However, training segmentation models may require manual labels in target domain, which is expensive and time-consuming.

Quality of Life Outcomes in Vestibular Schwannoma: A Prospective Analysis of Treatment Modalities

The Laryngoscope, EarlyView.
One of the first prospective cohort studies looks at quality of life (QOL) outcomes for the three main treatment modalities for vestibular schwannoma. In our study, we found comparable long‐term disease‐specific QOL outcomes, which will allow clinicians to more accurately counsel patients before making life‐changing treatment decisions.

Plexiform Schwannoma of the Tongue in a Pediatric Patient with Neurofibromatosis Type 2: A Case Report and Review of Literature

Case Reports in Pathology, 2018
Introduction. Plexiform schwannoma is a rare variant of schwannoma that accounts for only 5% of all schwannomas. Herein, we present a rare case of plexiform schwannoma of the tongue in a pediatric patient with neurofibromatosis type 2 (NF2).

Comparing Tinnitus Suppression in Asymmetric Hearing Loss and Single‐Sided Deafness: Cochlear Versus Bone Conduction Implants

The Laryngoscope, EarlyView.
While both cochlear implants and bone conduction implants improve tinnitus symptoms, cochlear implants provide significantly greater suppression across multiple tinnitus severity measures and a higher cure rate, positioning it as the preferred option for tinnitus management in asymmetric hearing loss and single‐sided deafness patients.

Intradural angiomatous meningioma arising from a thoracic nerve root [PDF]

, 2017
BACKGROUND: Spinal intradural meningiomas that arise purely from a nerve root without dural attachments are extremely rare. Spinal meningiomas arise from arachnoidal cap cells in the spinal canal, and growth of these tumors exerts pressure on the spinal ...

Automatic Segmentation of Vestibular Schwannoma from T2-Weighted MRI by Deep Spatial Attention with Hardness-Weighted Loss [PDF]

, 2019
Automatic segmentation of vestibular schwannoma (VS) tumors from magnetic resonance imaging (MRI) would facilitate efficient and accurate volume measurement to guide patient management and improve clinical workflow. The accuracy and robustness is challenged by low contrast, small target region and low through-plane resolution.

An Unpaired Cross-modality Segmentation Framework Using Data Augmentation and Hybrid Convolutional Networks for Segmenting Vestibular Schwannoma and Cochlea [PDF]

arXiv, 2022
The crossMoDA challenge aims to automatically segment the vestibular schwannoma (VS) tumor and cochlea regions of unlabeled high-resolution T2 scans by leveraging labeled contrast-enhanced T1 scans. The 2022 edition extends the segmentation task by including multi-institutional scans.

The 3D‐Robotic Exoscope Compared With the Microscope in Cochlear Implant and Translabyrinthine Surgery

The Laryngoscope, EarlyView.
The 3D‐exoscope is an innovative viewing platform in microsurgery with the potential of offering improved ergonomics and surgical performance. This prospective study systematically evaluated the ergonomic characteristics, visualization, and subjective performance of an exoscope system compared to the microscope in lateral skull base surgery (cochlear ...

Weakly Unsupervised Domain Adaptation for Vestibular Schwannoma Segmentation [PDF]

arXiv, 2023
Vestibular schwannoma (VS) is a non-cancerous tumor located next to the ear that can cause hearing loss. Most brain MRI images acquired from patients are contrast-enhanced T1 (ceT1), with a growing interest in high-resolution T2 images (hrT2) to replace ceT1, which involves the use of a contrast agent.
