Article Abstract
Background: Significant volume changes at the site of lateral window maxillary sinus floor elevation have been reported 6 months postoperatively, with stabilization thereafter. However, at present, there is no consensus regarding the gold standard to assess the shape and volume of the bone graft site after implantation. This study aimed to analyze volume changes in the lateral window maxillary sinus floor elevation region using Minics software.
Methods: We analyzed 40 patients who underwent lateral window maxillary sinus floor elevation surgery at the Stomatology Department of Binhaiwan Central Hospital, Dongguan, China between 2017 and 2020. Twenty patients underwent lateral window maxillary sinus floor elevation with simultaneous implantation, while 20 patients underwent lateral window maxillary sinus floor elevation with delayed implantation 6 months later. Minics software was used for three-dimensional analysis of the elevation site on the day after surgery (T1) and 6 months after surgery (T2) in both groups.
Results: The elevation site volume was reduced 6 months after lateral window maxillary sinus floor elevation. The differences in the length, width, height from the tip, and volume of the implant between T1 and T2 were statistically significant.
Conclusions: The length, width, height, and volume of the lateral window maxillary sinus floor elevation region were reduced using Minics software, suggesting that the volume of the elevation site should be enlarged as much as possible during the operation to prevent volume shrinkage.

Long-term stability of transcrestal sinus augmentation.

Transcrestal sinus augmentation has emerged as a minimally invasive alternative to lateral window techniques for vertical bone augmentation in the edentulous maxilla. Since its early introduction and modification over the last several decades, this technique has demonstrated predictable outcomes for implant placement in regions with limited bone height. This narrative review examines the current understanding and evolution of transcrestal sinus floor elevation (TSFE), focusing on factors related to long-term stability.

Objective: We investigated the effects of C9orf72 mutation carriership on peripheral nerve excitability in asymptomatic individuals from families with a history of C9orf72 amyotrophic lateral sclerosis (ALS) and patients.
Methods: We included 47 asymptomatic individuals from families with a history of C9orf72 ALS, of whom 23 were carriers (C9) and 24 were noncarriers (C9). In addition, 11 C9 and 110 C9 ALS patients and 50 healthy controls participated.
Subsidence reduction effect of transforaminal lumbar interbody fusion (TLIF) with upper and lower open windows modified with lattice structure.

Cage subsidence is a common complication following transforaminal lumbar interbody fusion (TLIF) that can lead to poor clinical outcomes, including recurrent pain and segmental instability. Conventional TLIF cage designs often fail to distribute stress evenly, increasing the risk of endplate damage and subsequent subsidence. This study aims to evaluate the effect of a modified TLIF cage with upper and lower open windows (lattice structure) in reducing cage subsidence in patients with lumbar degenerative disc disease (LDDD).

Conventional optical probes suffer from signal degradation in aqueous media, hindering sensitive biodetection. To overcome this, newly developed water-insensitive down-shifting nanoparticles (WINPs) possess superior photophysical properties in the NIR-I window, including high quantum yield and negligible thermal effects, permitting stable, high-contrast signal generation under low excitation power. This advantage facilitated a low-power lateral flow assay capable of highly sensitive avian influenza virus (AIV) detection in the opaque biological matrices (such as avian swabs), mitigating interference issues relying on visible-range signals.

Oblique lumbar interbody fusion (OLIF) is a minimally invasive technique for the treatment of degenerative diseases of the lumbar spine, and the left operative window is always used to avoid the inferior vena cava (IVC). However, in cases with anatomical variations-particularly vascular anomalies, which most significantly impact surgical approaches-the right retroperitoneal approach may serve as a preferable alternative. This case report describes a 59-year-old man with lumbar instability and a rare left-sided IVC who underwent OLIF via a right approach.
