“…The distance from the supraorbital notch to the optic canal ranges from 44.05 mm to 53.25 ± 1.24 mm. 5 At its medial border, the orbital roof is joined from anterior to posterior by the frontal process of the maxilla, the posterior lacrimal crest of the lacrimal bone and the ethmoid bone. Laterally, the roof joins the zygoma anteriorly and the greater wing of the sphenoid posteriorly.…”

This contains the notch, or canal, of the supraorbital nerve, which can be easily palpated approximately one-third of the way from the medial edge.…”

Purpose: To explore the anatomy, etiopathogenesis, diagnosis and classification, current evidence on intervention and the surgical management of orbital roof fractures and defects (ORFD) for oculoplastic surgeons presented with such cases. Methods: A review of the current literature through the MEDLINE database using the following search terms: “orbital roof fracture (+treatment/management),” “orbital roof defect (+treatment/management),” “orbital roof erosion (+treatment/management),” “orbital roof repair,” “orbital roof,” “orbital fracture,” “pediatric orbital roof (defect/fracture/erosion),” “orbital anatomy,” and “orbital roof anatomy” was conducted. As relatively little has been published on this topic, inclusion criteria were broad and peer-reviewed articles judged to be of clinical importance, relevant to the aims of this review, were included. Non-English abstracts were also included if relevant. Year of publication was not a strict exclusion criterion, and older articles were judged for their suitability based on clinical importance and relevance to current practice. Additional references were obtained from citations in key articles and recommendations from the coauthors based on their areas of expertise. Results: The etiopathogenesis of ORFD varies. Classification systems have been formulated to guide management decisions and can range from conservative management to complex neurosurgery. Eyelid approaches have also been described. This review provides a summary of the evidence for each and a management framework oculoplastic surgeons can use when presented with ORFD. Conclusion: Oculoplastic surgeons can be involved, either alone or as part of a multidisciplinary team, in the management of ORFD, and for some, conduct orbital approach reconstructive surgery.

“…29 Both studies postulate that tight orbits and dry eye syndrome in females may account for these findings. 8,29 In general, females have smaller orbital dimensions than males, 30 and this may lead to compression of the implant against ocular tissues, thereby leading to gradual patch and conjunctival atrophy and increasing the risk of exposure. Patients with dry eye syndrome may experience repetitive microtrauma that may compromise conjunctival integrity and increase risk of exposure.…”

In recent years, there has been a paradigm shift in glaucoma surgical procedures. Glaucoma drainage implant (GDI) surgeries are being performed much more commonly. Thus, it is important for surgeons to be cognisant of potential complications and their management. Exposure of a GDI is a well‐known complication, and prompt recognition and treatment are required to prevent endophthalmitis, a potentially blinding condition. In this review, we discuss the mechanisms and risk factors for GDI exposure, highlight important considerations for repair, and discuss repair techniques, with the aim of improving patient outcomes and minimising the risk of re‐exposure.

Objective: The intent of this chapter is to provide a systematic reappraisal of the bony anatomy of the orbit. The studies and the available literature on this topic are ever-expanding. The present knowledge shall be put into perspective.Material and Methods: Textbook and atlas descriptions served as a starting point for a comprehensive outline of the osseous anatomy of the orbits. To deepen the insight and understanding, a small selection of recent reports on specific structures has been reviewed. For visual purposes, photographs of PMHS (post mortem human subject) specimens and illustrations were used.Review/Results: The most distinctive feature of each orbit is the quadrangular pyramidal shape with a tetrahedron spire making up the orbital apex. The bony elements of the orbits are delineated with the sphenoid as backward foundation and starting base for the overall architectural composition. A closer look goes into the openings within the orbital precincts and reveals the subtleties and variations of the fissures, canals, grooves, foramina, notches, and fossae monitoring recent publications. The research modalities of these studies have shifted from dry skull investigations and PMHS dissections to modern imaging techniques (CT, MRI, CBCT) within defined living populations facilitating the analysis of hidden spaces or hard-to-reach structures in a non-destructive manner. Additional advantages of imaging include quantification and a detailed morphometric evaluation in the spirit of computational anatomy.Conclusion: In essence, the combination of traditional anatomic knowledge and the understanding of the tremendous complexity of variations characterized in new publications demands for a patient-specific diagnostic workup as exemplified in this book. As a matter of fact, however it is more likely to recognize and grasp features that one knows or knows about from previous intensive learning.

Orbital Morphometry

Abstract: This study provides the absolute limit of safe internal orbital dissection in respect to the local population. Despite males having larger orbits than females, it is clinically negligible.
