Altered cerebral white matter network topology and cognition in children with obstructive sleep apnea.

Objectives: The study aimed to explore the underlying mechanisms of OSA-related cognitive impairment by investigating the altered topology of brain white matter networks in children with OSA.

Methods: Graph theory was used to examine white matter networks' network topological properties in 46 OSA and 31 non-OSA children. All participants underwent MRI, polysomnography, and cognitive testing.

Alterations of brain gray matter volume in children with obstructive sleep apnea.

Objective: Obstructive sleep apnea (OSA) seriously affects the children's cognitive functions, but the neuroimaging mechanism of cognitive impairment is still unclear. The purpose of our study was to explore the difference in brain local gray matter volume (GMV) between children with OSA and non-OSA, and the correlation between the difference regions of brain gray matter volume and cognitive, the severity of OSA.

Method: Eighty-three children aged 8-13 years were recruited in our study, 52 children were diagnosed as OSA by polysomnography, and 31 as the non-OSA.

Cochlear implantation surgery in patients with narrow facial recess.

Conclusion: The new method of facial recess enlargement through suspending, antedisplacing, and adhering the chorda tympani nerve to the posterior wall of the auditory canal can expose the round window, make electrode insertion easier, and preserve the function of the facial nerve and chorda tympani nerve.

Objective: To describe and report cochlear implantation surgery in patients with narrow facial recess, including surgical technique and postoperative outcomes.

Methods: Cochlear implantation surgery was performed in our hospital in 39 cases with narrow facial recess by enlarging the facial recess.
