“…Navigation-assisted primary reconstructions of the orbit offer important advantages but few cases have been described in the literature, as a result of the complicated preoperative preparations that are required (4,7,(35)(36)(37). To date, invasive registration methods have been the only way to perform computer-assisted procedures with acceptable accuracy.…”

Background Management of orbital and mid-facial fractures requires a thorough ophthalmic evaluation and precise imaging. A principle goal of therapy is to anatomically reduce fracture segments and to restore a normal orbital volume as soon as possible. Diagnostic advances such as new surgical and imaging techniques have dramatically improved both the functional and aesthetic outcome of reconstructions.

“…Altersbedingte Veränderungen im Oberflächenrelief der internen Orbita, d. h. vor allem der Orbitaboden und die mediale Orbitawand mit der für die Vertikalposition und Projektion des Bulbus oculi wichtigen posteromedialen Konvexität ("posterior medial bulge") und zugehörige Parameter wie das Orbitavolumen, entziehen sichtrotz zahlreicher Untersuchungen zu Durchschnittswerten [46,47,63,68] bisher einer exakten Quantifizierung [51,71]. Festzuhalten bleibt, dass der tiefste Punkt des Orbitabodens im fortgeschrittenen Alter weiter hinten und unten zu finden ist und die Schrägneigung gegenüber der Horizontalebene abnimmt [11].…”

ZusammenfassungCMF-Traumen im Alter 65+ sind durch besondere Merkmale gekennzeichnet: Lokalisation und Frakturmuster, Stand des Involutionsprozesses mit Abnahme von Knochenquantität und -qualität, Begleitverletzungen, altersassoziierte physische und psychische Funktionseinbußen und präexistente Komorbiditäten. Der Stand des Wissens und aktuelle bevölkerungsbezogene Daten dieser Variablen werden zu Anfang dieser Übersicht dargestellt. Vor diesem Hintergrund wird dann zu den verschiedenen Frakturen und Frakturtypen in den einzelnen Regionen des Gesichtsschädelskeletts Stellung genommen und die Indikation zu einem konservativen oder operativen Prozedere in den Alterspopulationen diskutiert. Spezielle Aufmerksamkeit kommt dabei Fraktursituationen bei Zahnlosigkeit und Atrophie im Ober- und/oder Unterkiefer zu. Innerhalb des weitgesteckten Gesamtspektrums der Frakturszenarien haben schonende, situationsadaptierte, ggf. auch unkonventinelle Lösungen Priorität vor Standardtherapieverfahren. Neue Techniken wie computerassistierte Chirurgie und patientenspezifische Implantate spielen eine immer größere Rolle und werden an Einzelbeispielen demonstriert. Betont werden muss, dass die physischen Reserven und nötigenfalls die geriatrietypische Multimorbidität jedes Patienten individuell einzuschätzen ist und vorrangige Bedeutung vor dem kalendarischen Lebensalter hat.

“…Detailed mapping of the complex bony surfaces of the orbit, in particular, the topography of the floor in transition to the medial wall including the so-called posterior medial bulge has been taken to a new level by automated analysis of computed tomographic (CT) data sets from routine examinations of patients with unaffected regional anatomy. 12,13,[38][39][40][41][42][43] In comparison to this, "big data mining" studies based on traditional manual caliper measurements must appear anachronistic. The visual impression of the published 3D orbital shapes and forms, however, elude exact narrative description and will need direct inspection in the respective articles.…”

“…41 The dimensions and volumes of the orbit vary greatly because of ethnic, gender, and age differences, and escape from normative quantification. 39 Although some values typically found in adults may serve as initial orientation: the anterior opening measures 4 cm horizontally and 3.5 cm vertically, the depth anteroposteriorly is approximately 4.5 to 5 cm-the overall orbital volume amounts to 30 mL, of which 7 mL go to the ocular globe volume. 15 For instance, the interindividual variation of orbital volumes for an European white ethnic group was lying between 20 to 29 mL (mean, 24.4 mL) in females and 22 to 32 mL (mean, 26.8 mL) in males.…”

The aim of this article is to update on anatomical key elements of the orbits in reference to surgical innovations. This is a selective literature review supplemented with the personal experience of the authors, using illustrations and photographs of anatomical dissections. The seven osseous components of the orbit can be conceptualized into a simple geometrical layout of a four-sided pyramid with the anterior aditus as a base and the posterior cone as apex. All neurovascular structures pass through bony openings in the sphenoid bone before diversification in the mid and anterior orbit. A set of landmarks such as the optic and maxillary strut comes into new focus. Within the topographical surfaces of the internal orbit the lazy S-shaped floor and the posteromedial bulge are principal determinants for the ocular globe position. The inferomedial orbital strut represents a discernible sagittal buttress. The periorbita and orbital soft tissue contents--extraocular muscles, septae, neurovasculature--are detailed and put into context with periorbital dissection.
