Goldenhar Syndrome: Quality-of-Life Analysis of 43 Consecutive Patients.

Goldenhar syndrome is a rare congenital disease, characterized by the malformation of craniofacial features, spine, and other organs. Its pathogenesis and impact on patients' quality of life (QoL) have not been fully elucidated as yet. Therefore, data of all patients with Goldenhar syndrome, who were treated at Hannover Medical School between 1997 and 2020, were analyzed. Forty-three patients were identified. Their medical records were carefully reviewed for data regarding their age, sex, demographics, Pruzansky classification, surgical history, and affected side. Goldenhar syndrome-associated medical conditions, therapeutic procedures, and the impact of disease on QoL were assessed. Their QoL was assessed using the Oral Health Impact Profile (OHIP)-14 questionnaire. The χ 2 test and Pearson correlation were performed for statistical evaluation. Female sex was positively correlated with OHIP outcomes, whereas male sex had a negative correlation with OHIP outcomes. Therefore, females had significantly worse QoL than males. No significant correlation was observed between the Pruzansky classification and QoL or between surgical history and QoL. Goldenhar syndrome is a rare disease that presents with varying severity. Hence, prospective studies are required to further investigate the impact of Goldenhar syndrome on the QoL.

Exceptional Cases Demand Exceptional Personalized Solutions: The Next Level in Dental Rehabilitation.

Defects and bone loss in the maxilla and mandible pose significant challenges for dental rehabilitation. This paper focuses on complex cases of bimaxillary dental rehabilitation, where traditional dental implant protocols were not feasible in at least one jaw. Four patients were examined conceptually, where conventional dental implant placement (n = 20) was combined in either the same or opposite jaw with a patient-specific subperiosteal implant (n = 5). This study evaluates aspects such as primary stability, prosthodontic restoration, complications, and soft tissue management over the observation period. None of the five patient-specific subperiosteal implants (IPS Implants® Preprosthetic; KLS-Martin Group, Tuttlingen, Germany) experienced failure or showed any loosening of screws, with the longest observation period extending to 68 months. These implants were securely fixated away from the posts, without any biomechanical restrictions on loading from the time of insertion. Planning and manufacturing, including the initial suprastructure, followed a fully digital workflow. The number of screws required for multivector fixation ranged from 13 to 22. All dental implants placed remain functional, definitive prosthodontic restoration has been performed, and no stability loss or peri-implantitis has been observed. The IPS Implants® Preprosthetic emerges as a valuable consideration when conventional implant dentistry protocols encounter limitations.

A Novel Method for Secondary Mandible Reconstruction to Re-Achieve a Native Condyle Position Comprising a New Design for Cutting Guides and New Positioning Devices.

Secondary mandibular reconstruction using fibular free flaps (FFF) is a technical challenge for surgeons. Appropriate operation planning is crucial for postoperative quality control and is notably necessary for the (re-) achievement of a physiological condylar position, and the sensible expansion and shaping of the transplant. Computer-assisted planning may help to reconstruct mandibular defects in a patient-specific and precise manner. Herein, we present a newly-developed workflow for secondary mandibular reconstruction using FFF; it comprises digital planning and in-house manufacturing to perform precise secondary mandible reconstruction. This method utilizes a newly designed positioning device to ensure the precise positioning of the fibula segments in relation to each other and the mandibular stumps. The presented in-house-printed positioning device made it possible to achieve digital planning with high precision during surgery.
