Immediate Postoperative Difference of Eyelid Height Based on Intraoperative Measurement of Levator Aponeurosis Advancement in Patients with Unilateral Ptosis.

Purpose: To determine the relationship between marginal reflex distance (MRD-1) outcomes and the distance of levator aponeurosis advancement.

Methods: This retrospective observational study included patients with acquired unilateral aponeurotic ptosis, who underwent small-incision anterior levator advancement. The distance of levator advancement, and intra-operative MRD-1 in the sitting position, were analyzed to determine a correlation between the two.

Changes in Eyelid Height Based on Intra-Operative Quantification of Levator Aponeurosis Advancement in Patients with Unilateral Ptosis.

Objective: To present marginal reflex distance (MRD-1) outcomes based on intra-operative quantification of levator aponeurosis advancement.

Methods: Forty-eight patients with unilateral aponeurotic ptosis underwent anterior levator aponeurosis advancement. Distance of advancement intra-operatively was compared with MRD-1 outcomes at the immediate postoperative sitting, approximately 1 week, and 1 month period.

Incommensurate grain-boundary atomic structure.

Grain-boundary atomic structures of crystalline materials have long been believed to be commensurate with the crystal periodicity of the adjacent crystals. In the present study, we experimentally observed a Σ9 grain-boundary atomic structure of a bcc crystal (Fe-3%Si). It is found that the Σ9 grain-boundary structure is largely reconstructed and forms a dense packing of icosahedral clusters in its core.

Late-Onset Traumatic Corneal Conjunctival Epithelial Disorders due to Granular Formation After Cosmetic Suture Blepharoplasty.

Purpose: The purpose of this study was to report conjunctival granular formation as one of the causative factors of a traumatic corneal conjunctival epithelial disorder after plastic suture blepharoplasty.

Methods: Clinical charts of 7 patients who had visited Ohshima Eye Hospital with a symptomatic corneal epithelial disorder and history of suture blepharoplasty were reviewed. Clinical evidence of conjunctival granular formations was observed in all patients at the tarsal conjunctiva facing to corneal conjunctival traumatic epithelial disorders.

Effectiveness of Thoracic Endovascular Aortic Repair for Blunt Thoracic Aortic Injury.

Purpose: Blunt thoracic aortic injury (BTAI) has a high mortality rate, and the occurrence of clinical complications is high. Several studies have reported the efficacy of thoracic endovascular aortic repair (TEVAR) for BTAI. This study aimed to clarify the use of TEVAR for BTAI.
