Place of Tubomanometry in Patulous Eustachian Tube Diagnosis.

Objective: The aim of our study was to describe the diagnostic performances of tubomanometry (TMM) and to determine tubomanometric parameter thresholds for the diagnosis of patulous eustachian tube (PET).

Study Design: We performed a retrospective, monocentric study, including patients treated for PET vs control group.

Setting: This study was performed at the Otolaryngology Department of a tertiary-care hospital in the south of France.

Navigation strategies in patients with vestibular loss tested in a virtual reality T-maze.

During navigation, humans mainly rely on egocentric and allocentric spatial strategies, two different frames of reference working together to build a coherent representation of the environment. Spatial memory deficits during navigation have been repeatedly reported in patients with vestibular disorders. However, little is known about how vestibular disorders can change the use of spatial navigation strategies.

Quantitative biomarkers allow the diagnosis of head and neck paraganglioma on multiparametric MRI.

Purpose: The aim of this study is to identify quantitative MR biomarkers in head and neck paragangliomas.

Methods: The study was approved by an institutional review board. A retrospective review of patients with head and neck paragangliomas (HNPGL) evaluated by time-resolved MRA sequences between 2009 and 2019 was performed.

Sunnybrook Facial Grading System: Intra-rater and Inter-rater Variabilities.

Objectives: Evaluate intra-rater and inter-rater variabilities of the Sunnybrook Facial Grading System (SFGS) and explore potential factors of variability.

Study Design: Prospective test of hypothesis.

Setting: University tertiary referral center.

Syngeneic Transplantation of Rat Olfactory Stem Cells in a Vein Conduit Improves Facial Movements and Reduces Synkinesis after Facial Nerve Injury.

Background: Posttraumatic facial paralysis is a disabling condition. Current surgical management by faciofacial nerve suture provides limited recovery. To improve the outcome, the authors evaluated an add-on strategy based on a syngeneic transplantation of nasal olfactory stem cells in a rat model of facial nerve injury.
