Outcomes and Innervation of Gracilis for Pediatric Facial Paralysis: A Systematic Review

open access: yesThe Laryngoscope, EarlyView.
This systematic review compares innervation techniques for gracilis free muscle transfer in pediatric facial paralysis. Masseteric innervation produced the greatest commissure excursion, cross‐facial nerve grafting enabled spontaneous smiles, and dual innervation balanced both with high satisfaction and low complication rates across techniques ...

Clinical Features and Dental Pathologies in Maxillary Sinus Fungal Balls and Odontogenic Sinusitis

open access: yesThe Laryngoscope, EarlyView.
This international, multicenter study compared clinical and dental characteristics of maxillary sinus fungal balls (MSFB), odontogenic MSFB (MSFBO), and odontogenic sinusitis (ODS). When MSFB and MSFBO were compared, MSFBO was associated with extruded root canal material and dental implant protrusion; when MSFBOs and ODS were compared, ODS was ...

An Improved Mesh Stiffness Model for a Gear Tooth With Double Cracks on Both Sides Considering Opened and Closed States

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Research on the failure mechanisms of gears with multiple cracks has gained widespread attention. Among these, the study of the mesh stiffness characteristics of gears with multiple cracks is crucial for optimizing gear design and improving transmission reliability.

Effect of Variations in the Ring Thickness on the Dynamic Performance of the Bimetal Gears

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study used a six‐degrees‐of‐freedom dynamic model to analyze the dynamic response of bimetal spur gears. Aluminum alloy forms the core of the bimetal gears, and a uniform‐thickness steel ring surrounds the teeth. Gear mesh stiffness of bimetal gears and the transmission error have been assessed using a numerical approach based on finite ...

Anisotropy Analysis of Bamboo and Tooth Using 4‐Angle Polarization Micro‐Spectroscopy

open access: yesNano Select, EarlyView.
Super‐resolution via orientation: spatial distribution of specific molecular vibrations are revealed at 1/20 of the diffraction limit. ABSTRACT To investigate the anisotropic properties of biomaterials, two distinct classes are considered as follows: polymer‐based (cellulose in plants) and crystalline‐based (enamel in teeth), each demonstrating ...
