Efficacy of modified anterior maxillary segmental distraction osteogenesis based on 3D visualisation for the treatment of maxillary hypoplasia among adolescents with cleft lip and palate.

Background: This study evaluates a three-dimensional (3D) visualisation design combined with customized surgical guides to assist anterior maxillary segmental distraction osteogenesis (AMSDO) in correcting maxillary hypoplasia in adolescents with cleft lip and palate (CLP), focusing on treatment outcomes, satisfaction and the validity of 3D planning.

Methods: This retrospective cohort study was conducted at a single hospital in China. Between January 2020 and December 2023, 12 adolescents with CLP with maxillary hypoplasia were included.

Discrimination of healthy oral tissue from oral cancer based on the mean grey value determined by optical coherence tomography.

Objective: This study aimed to identify a quantitative index for optical coherence tomography (OCT) images to discriminate tumours from surrounding tissues.

Subjects And Methods: Based on OCT measurements, mean grey values were determined from 432 locations on fifty-four human tissue specimens (eighteen cancerous, para-cancerous, and normal tissues each). These results were histologically evaluated by hematoxylin and eosin staining (H&E).

Modified patient-specific surgical-guide-assisted precise treatment of unilateral comminuted zygomaticomaxillary complex fractures: A 5-year retrospective study.

Our study aimed to evaluate modified patient-specific surgical-guide-assisted precise treatment of unilateral comminuted zygomaticomaxillary complex (ZMC) fractures. The retrospective non-randomized study was conducted in a single hospital in China. All patients diagnosed with unilateral comminuted ZMC fractures between January 1, 2018 and December 31, 2022 were retrospectively reviewed.

Digitally reconstructed severe trauma-induced oro-maxillofacial defects with free vascularised composite tissue flaps.

The aim of this study was to outline the characteristics of severe trauma-induced oro-maxillofacial defects and explore the application of microsurgical reconstruction of these defects by selecting appropriate free vascularised composite tissue flaps. A retrospective analysis was performed in 11 cases with severe trauma-induced oromaxillofacial defects from 2005 to 2018, All cases were reconstructed with free vascularised composite flaps using a supermicro-surgical/micro-surgical and digital technology. This study consisted of 11 patients (8 men, 3 women) with a median age (range) of 28 (6-64) years.

Associations between condylar fractures and external auditory canal fracture: A 7-year retrospective study.

The study aimed to investigate whether the incidence rate of external auditory canal (EAC) fracture varies among different clinical types of condylar fracture. A retrospective cohort study was conducted in single hospital of China. Eligible patients diagnosed with mandibular condylar fractures were retrospectively reviewed.

Analysis of Maxillofacial Fractures Based on the Etiology in Southeast China: A 10-Year, Multi-Center Study.

Background: The aim of this study was to explore the characteristics and correlation of maxillofacial fractures and concurrent injuries with different injury causes.

Methods: In this retrospective study, data were collected from patients treated for maxillofacial fractures in 3 oral and maxillofacial surgery departments in Southeast China, from January 2010 to December 2019. The information was obtained from clinical notes and surgical records using a standardized data collection form, and some causes of injuries were confirmed by telephone follow-ups and police records.
