Longitudinal Three-Dimensional Follow-Up and Secondary Treatment Aspects after Endoscopic and Open Scaphocephaly Surgery.

Background: This retrospective cohort study evaluated the longitudinal three-dimensional cranial shape developments and the secondary treatment aspects after endoscopically assisted craniosynostosis surgery (EACS) with helmet therapy and open cranial vault reconstruction (OCVR) for scaphocephaly.

Methods: Longitudinally collected three-dimensional photographs from scaphocephaly patients and healthy infants were evaluated. Three-dimensional cranial shape measurements and growth maps were compared between the groups over time.

Toward Holographic-Guided Surgery.

The implementation of augmented reality (AR) in image-guided surgery (IGS) can improve surgical interventions by presenting the image data directly on the patient at the correct position and in the actual orientation. This approach can resolve the switching focus problem, which occurs in conventional IGS systems when the surgeon has to look away from the operation field to consult the image data on a 2-dimensional screen. The Microsoft HoloLens, a head-mounted AR display, was combined with an optical navigation system to create an AR-based IGS system.

A novel semi-automatic segmentation protocol for volumetric assessment of alveolar cleft grafting procedures.

A novel protocol for volumetric assessment of alveolar cleft grafting procedures is presented. Eleven cone-beam computed tomography (CBCT) datasets of patients who underwent secondary alveolar cleft reconstructive surgery for a unilateral alveolar cleft were evaluated by two investigators. Residual bone volumes 1 year after surgery were analysed using a semi-automated technique in which preoperative CBCT datasets were superimposed on the postoperative scans using voxel-based registration.

Radiation-free 3D head shape and volume evaluation after endoscopically assisted strip craniectomy followed by helmet therapy for trigonocephaly.

Introduction: Radiation-free 3D post-operative sequential follow-up in craniosynostosis is hindered by the lack of consistent markers restricting evaluation to subjective comparison. However, using the computed cranial focal point (CCFP), it is possible to perform correct sequential image superposition and objective evaluation. We used this technique for mean volume and shape change evaluation of the head utilizing 3D photos after endoscopically assisted trigonocephaly surgery.

Endoscopically assisted craniosynostosis surgery (EACS): The craniofacial team Nijmegen experience.

Introduction: An evaluation of our first 111 consecutive cases of non-syndromic endoscopically assisted craniosynostosis surgery (EACS) followed by helmet therapy.

Methods: Retrospective analysis of a prospective registration database was performed. Age, duration of surgery, length of hospital stay, blood loss, transfusion rate, cephalic index and duration of helmet therapy were evaluated.

Secondary closure of small- to medium-size palatal defects after ablative surgery: reappraisal of reconstructive techniques.

Purpose: Postoncologic reconstruction of the palate represents a major surgical challenge with respect to the thin intraoral and intranasal lining. Current reconstructive methods have ranged from obturative closure of the defect to microsurgical free tissue transfer. The final choice of treatment will be influenced by the size and location of the defect and surgeon experience.

Validation of cephalic index measurements in scaphocephaly.

Introduction: The cephalic index (CI) of the head can be measured manually using a caliper, the original technique, but it is also possible to determine it using skull X-ray, 2DCT and 3DCT images, 3D photo and with help of plagiocephalometry (PCM).

Patients And Methods: In this study, the manual caliper determination is statistically compared with other measuring methods for scaphocephaly patients (n = 39).

Results: The CI mean differences for the most representative data are sequentially 3.

Nasolabial symmetry and aesthetics in children with complete unilateral cleft lip and palate.

The objective of this study was to evaluate the association between nasolabial symmetry and aesthetics in children with complete unilateral cleft lip and palate (CUCLP). Frontal and basal photographs of 60 consecutively treated children with CUCLP (cleft group: 41 boys and 19 girls, mean (SD) age 11 (2) years) and 44 children without clefts (control group: 16 boys and 28 girls, mean (SD) age 11(2) years), were used for evaluation of nasolabial symmetry and aesthetics. Nasal and labial measurements were made to calculate the coefficient of asymmetry (CA).

3D stereophotogrammetric analysis of lip and nasal symmetry after primary cheiloseptoplasty in complete unilateral cleft lip repair.

Background: The aim of this study was to evaluate symmetry of the lip and nose in patients with CUCLP after primary cheiloseptoplasty (Afroze technique), in comparison to non-cleft controls.

Methodology: In this prospective study, forty-four patients with operated non-syndromic CUCLP were included. The control group consisted of 44 volunteers without cleft defects of approximately the same age and sex.

Postoperative volume increase of facial soft tissue after percutaneous versus endonasal osteotomy technique in rhinoplasty using 3D stereophotogrammetry.

Background: When lateral osteotomies are performed as part of a rhinoplasty, the nose and paranasal region invariably change in three dimensions. The PURPOSE of this study is to compare the effect of the percutaneous perforating and endonasal continuous osteotomy techniques concerning the degree of postoperative swelling using three dimensional (3D) stereophotogrammetry.

Methodology: A prospective follow-up study was conducted.

Digital three-dimensional image fusion processes for planning and evaluating orthodontics and orthognathic surgery. A systematic review.

The three important tissue groups in orthognathic surgery (facial soft tissues, facial skeleton and dentition) can be referred to as a triad. This triad plays a decisive role in planning orthognathic surgery. Technological developments have led to the development of different three-dimensional (3D) technologies such as multiplanar CT and MRI scanning, 3D photography modalities and surface scanning.

Registration of 3-dimensional facial photographs for clinical use.

Purpose: To objectively evaluate treatment outcomes in oral and maxillofacial surgery, pre- and post-treatment 3-dimensional (3D) photographs of the patient's face can be registered.

A web based survey was set up, showing records of four patients with different conditions: hemifacial microsomia (case 1), bilateral mandibular deficiency (case 2), cleft lip and palate (case 3) and Crouzon syndrome (case 4). Respondents from 181 Eurocleft centres were asked to fill out a questionnaire for each patient.

Unilateral craniosynostosis of the frontosphenoidal suture: a case report and a review of literature.

Introduction: Frontal plagiocephaly, a rare congenital deformation of the skull, is one of the most complicated forms of craniosynostosis to treat. The difference between deformational and synostotic frontal plagiocephaly is small. Moreover, the visible deformations are sometimes misleading and may lead to a treatment delay.

The influence of the sagittal split osteotomy on the condylar cartilage structure and the subchondral vascularization of the temporomandibular joint: a preliminary study in goats.

Objective: The concern that a sagittal split osteotomy of the mandibular ramus could compromise the subchondral vascularization and especially the venous outflow in the condylar area, which in turn could influence the structure of the condylar cartilage, prompted this preliminary study on goats.

Study Design: A sagittal split osteotomy was performed in the mandibular ramus at 1 side in each of 6 young adult goats. The contralateral side served as control.
