Quantitative Evaluation of Improvement of Tear Trough With a Non-Cross-Linked Sodium Hyaluronic Compound: A Three-Dimensional and MRI Analysis.

Background: Tear trough deformities are indicative of aging, progressively manifesting as pronounced infraorbital hollows. Although hyaluronic acid (HA) dermal fillers are favored for their safety and efficacy, quantifiable evidence of their effect of action still remains insufficient.

Aims: To investigate the efficacy of non-cross-linked HA compound in tear trough enhancement.

Analysis of Preoperative Factors Influencing Hypoglossal-facial 'Side'-to-side Neurorrhaphy for Facial Paralysis after Excision of Acoustic Neuroma.

Objective: Hypoglossal nerve-facial nerve 'side'-to-side neurorrhaphy is a new method for the treatment of potential incomplete facial paralysis after acoustic neuroma. However, there are differences in postoperative outcomes among patients. This study analysed preoperative factors that may influence the treatment outcomes of neurorrhaphy.
