The primary challenges in scalp reconstruction are the relative inelasticity of native scalp tissue and the convex shape of the calvarium. All rungs of the reconstructive ladder can be applied to scalp reconstruction, albeit in a nuanced fashion due to the unique anatomy and vascular supply to the scalp. Important defect variables to incorporate into the reconstructive decision include site, potential hairline distortion, size, depth, concomitant infection, prior radiation therapy, planned adjuvant therapy, medical comorbidities, patient desires, and potential calvarium and dura defects.

Previous studies have demonstrated that the speech reception threshold (SRT) can be estimated using scalp electroencephalography (EEG), referred to as SRT. The present study assesses the feasibility of using ear-EEG, which allows for discreet measurement of neural activity from in and around the ear, to estimate the SRT.Twenty young normal-hearing participants listened to audiobook excerpts at varying signal-to-noise ratios (SNRs) whilst wearing a 66-channel EEG cap and 12 ear-EEG electrodes.

Previous studies have demonstrated the feasibility of estimating the speech reception threshold (SRT) based on electroencephalography (EEG), termed SRT, in younger normal-hearing (YNH) participants. This method may support speech perception in hearing-aid users through continuous adaptation of noise-reduction algorithms. The prevalence of hearing impairment and thereby hearing-aid use increases with age.

Background: We aimed to assess the efficacy of augmented reality technology assisted by three-dimensional (3D) computed tomography (CT) reconstruction, in facilitating microvascular decompression (MVD) during craniotomy for hemifacial spasm.
Methods: A retrospective analysis was conducted on 80 patients who underwent MVD for hemifacial spasm at Hebei General Hospital between January 2, 2020, and March 24, 2021. Among them, 43 patients received traditional craniotomy (assigned to the traditional group), while 37 patients underwent modified craniotomy (assigned to the modified group).

Fibrous dysplasia (FD) is a rare, benign bone developmental disorder that predominantly affects adolescents and young adults. Cranial bones are rarely involved. The definitive treatment for craniofacial FD in adults is complete resection and reconstruction.

Orthogonal Tchebichef moments of fractional order (FrTMs) serve as descriptors for signals and images. Many fields, including signal analysis and watermarking, have relied heavily on such moments. This study addresses three critical limitations in existing approaches: the computational burden of higher-order moment calculations, numerical instability affecting reconstruction accuracy, and orthogonality deterioration in large-scale signal processing.
