This thesis focuses on craniosynostosis, a condition where the bones of a baby’s skull fuse prematurely, potentially leading to abnormal skull shapes and developmental issues. The research emphasizes the use of non-invasive 3D imaging techniques, such as photogrammetry, to assess and analyze cranial and facial structures without the need for radiat...

Background The aim of this study is to describe and compare head shape in surgically and conservatively treated patients using 3D photogrammetry. Methods A retrospective review (2017-2020) of consecutive patients with isolated metopic synostosis based on 3D photogrammetry was conducted at the age of 4 years old. Images were aligned using a healthy...

Craniosynostosis, a congenital condition characterized by the premature fusion of cranial sutures, necessitates objective methods for evaluating cranial morphology to enhance patient treatment. Current subjective assessments often lead to inconsistent outcomes. This study introduces a novel, quantitative approach to classify craniosynostosis and me...

To determine the skeletal changes after midface surgery in patients with syndromic craniosynostosis who underwent Le Fort III (LFIII), monobloc (MB), or facial bipartition (FB). This was a retrospective study including 75 patients: 33 treated by LFIII, 29 by MB, and 13 by FB. Twenty-five had a diagnosis of Apert, 39 Crouzon, and 11 craniofrontonasa...

With increasing interest in 3D photogrammetry, diverse methods have been developed for craniofacial shape analysis in craniosynostosis patients. This review provides an overview of these methods and offers recommendations for future studies. A systematic literature search was used to identify publications on 3D photogrammetry analyses in craniosyno...

Craniosynostosis, characterized by premature fusion of one or more cranial sutures, results in a distorted skull shape. Only three studies have assessed facial asymmetry manually in unicoronal synostosis patients. It is therefore important to understand how uni- and bicoronal synostosis affect facial asymmetry with a minimum risk of human bias. An...

This study aimed to assess the reliability and agreement of automated head measurements using 3-dimensional (3D) photogrammetry in young children. Specifically, the study evaluated the agreement between manual and automated occipitofrontal circumference (OFC) measurements (n = 264) obtained from 3D images of 188 patients diagnosed with sagittal syn...

CraniumPy is an open-source platform for streamlined 3D craniofacial image processing, encompassing image alignment, optimization, and analysis. Our study assesses the efficacy of its novel algorithm in automatically deriving head measurements from 3D images and compares these to manually acquired measurements to evaluate reliability and interchang...

Objective: The aim of this study is to compare three surgical interventions to correct sagittal synostosis: frontobiparietal remodeling (FBR), extended strip craniotomy (ESC), and spring assisted correction (SAC), based on 3D photogrammetry and operation characteristics. Methods: All patients diagnosed with non-syndromic sagittal synostosis, bor...

CraniumPy is a simple tool that can be used to register 3D meshes for cranial analysis using three landmarks. In its current state, a raw 3D mesh (.ply, .obj, .stl) can be imported and visualized. After registration, cephalometric measurements can be automatically extracted. https://github.com/T-AbdelAlim/CraniumPy

Three-dimensional (3D) stereophotogrammetry is a novel imaging technique that has gained popularity in the medical field as a reliable, non-invasive, and radiation-free imaging modality. It uses optical sensors to acquire multiple 2D images from different angles which are reconstructed into a 3D digital model of the subject's surface. The technique...

This article reviews the development of research in the field of craniosynostosis from a bibliometric standpoint. Craniosynostosis is a malformation occurring during the early development of the skull, when one or more of the sutures close too early, causing problems with normal brain and skull growth. Research in this field has developed from earl...
