Facial Foramen Diagnostic and Surgical Role as Reference Points in Asymmetries-Cone-Beam Computed Tomography Preliminary Study.
J Clin Med
January 2025
Department of Pediatric Dentistry and Preclinical Dentistry, Medical University in Wroclaw, Krakowska 26, 50-425 Wrocław, Poland.
Facial asymmetry can be attributed to a multitude of underlying causes. Multiple reference points can be utilized for guidance in surgery planning. The scope of mandibular overgrowth and asymmetry should always be measured on CBCT radiographs (cone-beam computed tomography).

Silver-Russell Syndrome (SRS) is a rare genetic disorder characterized by prenatal and postnatal growth restriction, distinctive facial features, and body asymmetry. Early suspicion during the first trimester remains challenging but crucial for optimizing clinical outcomes. This study aims to highlight a diagnostic approach to the early suspicion of SRS.

Sci Rep

Department of Oral and Maxillofacial Surgery, Gangnam Severance Hospital, Yonsei University College of Dentistry, 211 Eonju-ro, Gangnam-gu, Seoul, 06273, Korea.
This retrospective study aimed to evaluate the difference in the temporomandibular joint (TMJ) space volume between the deviated (Dev) and non-deviated (NDev) side following transoral vertical ramus osteotomy (TOVRO) in patients with mandibular prognathism combined with asymmetry using reconstructed 3-dimensional images. Sixty joints from 30 patients who underwent TOVRO between January 2018 and December 2021 were included. Computed tomography (CT) or cone-beam CT was performed before surgery (T0), and 6 (T1) and 12 months postoperatively (T2).

In this paper, we present the first publicly available 3D statistical facial shape model of babies, the Baby Face Model (BabyFM). Constructing a model of the facial geometry of babies entails specific challenges, such as occlusions, extreme and uncontrollable expressions, and data shortage. We address these challenges by proposing (1) a non-template dependent method that jointly estimates a 3D facial baby-specific template and the point-to-point correspondences; (2) a novel method to establish correspondences based on the spectral decomposition of the Laplace Beltrami Operator, which provides a more robust theoretical foundation than state-of-the-art methods; and (3) an asymmetry-swapping strategy to alleviate the shortage of large scale datasets by decoupling the identity-related and the asymmetry-related shape deformation fields.

Department of Dentistry, State University of Maringá (UEM), Maringá, Brazil.
Background: Hybrid Odontogenic Tumors (HOT) are defined by the presence of two or more independent odontogenic tumors that originate from and affect the same maxillofacial site.
Methods: The present study is the first case report of a mandibular HOT consisting of Ameloblastoma, Calcifying Epithelial Odontogenic Tumor, and Ameloblastic Fibroma.
Case Report: A 37-year-old otherwise healthy male presented with the chief complaint of swelling in the right mandibular body.
