Abstract
Diagnosis and therapy of orbital diseases is an interdisciplinary challenge, in which i.e. otorhinolaryngologists, ophthalmologists, radiologists, radiation therapists, maxillo-facial surgeons, endocrinologists, and pediatricians are involved. This review article describes frequent diseases which both, otolaryngologists and ophthalmologists are concerned with in interdisciplinary settings. In particular the inflammatory diseases of the orbit including orbital complications, autoimmunological diseases of the orbit including Grave´s orbitopathy, and primary and secondary tumors of the orbit are discussed. Beside describing the clinical characteristics and diagnostic steps the article focusses on the interdisciplinary therapy. The review is completed by the presentation of most important surgical approaches to the orbit, their indications and possible complications. The authors tried to highlight the relevant facts despite the shortness of the text.

Abstract
PURPOSE To review the advances in the surgical techniques of orbital decompression. METHODS A literature review of orbital decompression surgery and experience-based consideration of bony areas for decompression. RESULTS In the 100-year-plus span of orbital decompression literature, multiple incisions and multiple bone and fat removal strategies have been described. In general, bone removal has been conceptualized as consisting of 4 walls of the orbit. However, the orbital bony anatomy is more subtle than a simple box, and considering 6 areas of potential bony removal allows a more nuanced paradigm for clinical decision-making and for understanding various technique descriptions. Historical and current techniques, and surgical planning and decision-making, are described from the perspective of a 6 area paradigm. Potential complications are reviewed. CONCLUSION A conceptual framework for orbital decompression focusing on 6 potential areas of bone removal provides a nuanced and flexible paradigm for understanding and describing surgical techniques, and for designing individualized surgery. Orbital decompression surgery should be customized to the patient's anatomy and symptoms.

Abstract
Abstract
Introduction Decompression of the optic nerve within the optic canal is indicated for compressive visual decline. The two most common approaches utilized for optic canal decompression are a medial approach with an endoscopic endonasal approach and a lateral approach with a craniotomy. Our study is a cadaveric anatomical study comparing the length and circumference of the orbit decompressed via an endoscopic endonasal approach versus a frontotemporal craniotomy.
Methods Five cadaveric specimens were utilized. Predissection computed tomography (CT) scans were performed on each specimen. On each specimen, a standard frontotemporal craniotomy with anterior clinoidectomy and superolateral orbital decompression was performed on one side and an endoscopic endonasal approach with medial wall decompression was performed on the contralateral side. Post-dissection CT scans were performed. An independent radiologist provided measurements of the length (mm) and circumference (degrees) of optic canal decompression bilaterally.
Results The mean length of optic canal decompression for open and endoscopic approach was 13 mm (range 12–15 mm) and 12.4 mm (range 10–16 mm), respectively. The mean circumference of decompression for open and endoscopic approaches was 252.8 degrees (range 205–280 degrees) and 124.6 degrees (range 100–163 degrees), respectively.
Conclusion The endoscopic endonasal and the transcranial approaches provide a similar length of optic canal decompression, but the transcranial approach leads to greater circumferential decompression. The endoscopic endonasal approach has the benefit of being minimally invasive, though. Ultimately, the surgical approach decision should be based on the location of the pathology and the surgeon's comfort.

An Anatomical Feasibility Study for Revascularization of the Ophthalmic Artery. Part II: Intraorbital Segment. World Neurosurg 2019; 133:401-408. [PMID: 31520756 DOI: 10.1016/j.wneu.2019.08.261] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2019] [Revised: 08/20/2019] [Accepted: 08/22/2019] [Indexed: 11/24/2022]
Abstract
INTRODUCTION Distal ophthalmic artery (OpA) aneurysms are a rare subset of vascular lesions with lack of optimal treatment. The management of these aneurysms may require complete occlusion of the parent vessel, carrying a risk of permanent visual impairment due to individual variations of extracranial collateral flow to the intraorbital ophthalmic artery (iOpA). OBJECTIVE To test the feasibility of a superficial temporal artery (STA) to iOpA bypass to prevent acute ischemic retinal injury. Two different transorbital corridors (superomedial and posterolateral approaches) for this bypass were evaluated. METHODS Each approach was carried out in 10 specimens each (n = 20). The corridors were compared to achieve the optimal exposure of the iOpA until the central retinal artery origin was visualized. An end-to-end anastomosis was performed from STA-to-iOpA. The arterial caliber and length at the anastomotic sites, required donor artery length, and intraorbital surgical area were measured. RESULTS STA-iOpA bypasses were performed in all specimens. For the posterolateral transorbital approach, the mean caliber of STA was 1.8 ± 0.2 mm, and that of iOpA was 1.7 ± 0.5 mm. The required STA graft length was 78.3 ± 1 mm with lateral iOpA transposition of 8.2 ± 1.1 mm. For the superomedial approach, the average STA length required for an intraorbital bypass was 130.8 ± 14.0 mm. The mean calibers of iOpA and STA were 1.5 ± 0.1 mm and 1.5 ± 0.1 mm, respectively. CONCLUSIONS This study demonstrates the feasibility of a novel revascularization technique of the iOpA using 2 different transorbital approaches. These techniques can be used in the management of intraorbital lesions such as OpA aneurysms, tumoral infiltrations, or intraoperative injuries.

Abstract
PurposeTo determine the safety and effectiveness of orbital decompression for thyroid eye disease (TED) in our unit. To put this in the context of previously published literature.Patients and methodsA retrospective case review of all patients undergoing orbital decompression for TED under the care of one orbital surgeon (SMS) between January 2009 and December 2015. A systematic literature review of orbital decompression for TED.ResultsWithin the reviewed period, 93 orbits of 55 patients underwent decompression surgery for TED. There were 61 lateral (single) wall decompressions, 17 medial one-and-a-half wall, 11 two-and-a-half wall, 2 balanced two wall, and 2 orbital fat only decompressions. For the lateral (single) wall decompressions, mean reduction in exophthalmometry (95% confidence interval (CI) was 4.2 mm (3.7-4.8), for the medial one-and-a-half walls it was 2.9 mm (2.1-3.7), and for the two-and-a-half walls it was 7.6 mm (5.8-9.4). The most common complications were temporary postoperative numbness (29% of lateral decompressions, 17% of other bony decompressions, OR 0.50, 95% CI 0.12-2.11) and new postoperative diplopia (9% of lateral decompressions, 39% of other bony decompressions, OR 6.8, 95% CI 1. 5-30.9). Systematic literature searching showed reduction in exophthalmometry for lateral wall surgery of 3.6-4.8 mm, with new diplopia 0-38% and postoperative numbness 12-50%. For other bony decompressions, reduction in exophthalmometry was 2.5-8.0 mm with new diplopia 0-45% and postoperative numbness up to 52%.ConclusionDiffering approaches to orbital decompression exist. If the correct type of surgery is chosen, then safe, adequate surgical outcomes can be achieved.

Abstract
INTRODUCTION Surgical rehabilitation of thyroid orbitopathy involves reducing proptosis, treating strabismus, lengthening the eyelids, and managing aesthetic changes. Not all are necessary in each patient; however, they often are. The current investigation intends to describe postdecompression changes that may influence the staging of these procedures. METHODS In this retrospective cohort study, records of 169 patients who underwent orbital decompression between 1983 and 2001 were reviewed. A single orbital specialist confirmed all measurements. Time to follow up was defined as the most recent follow up after decompression and prior to any secondary procedures. No strabismus or eyelid surgery was performed at the time of decompression. Strabismus was measured with alternating prism cover test. Ductions were estimated utilizing Hirschberg's method. Exophthalmometry was measured with Hertel. Eyelid positions were defined relative to the pupillary light reflex. Strabismus data were analyzed within eye pairs. Ductions, exophthalmometry and eyelid position were analyzed for each eye. T-test for paired data was utilized to compare means pre- and postoperatively. RESULTS The study population was on average 45 years old and 73.4% women. Average length of follow up was 1.2 years. Esotropia was significantly increased after decompression by an average of 8.1 prism diopters (p < 0.01). Exotropia and vertical deviations were not significantly altered. Ductions decreased by >5 degrees in at least one meridian for 68.1% of the population. Upper eyelid retraction remained unchanged; however, lower eyelid retraction improved by 50% from 1.4 mm to 0.7 mm (p < 0.01). Exophthalmometry improved from 23.5 mm to 19.7 mm (p < 0.01), and this result was correlated with the number of walls removed (Pearson r = -0.302, p < 0.01). CONCLUSIONS On average, esotropia and ductions tend to worsen with decompression surgery. This result supports the clinical dictum to avoid strabismus surgery until after decompression. The improvement in lower eyelid retraction suggests that at least lower eyelid-lengthening surgery should be reserved for after decompression, as there may be significant spontaneous improvement, while the same may not be true for upper eyelid retraction, which does not tend to change with decompression.

Abstract
INTRODUCTION Thyroid eye disease (TED) remains a notorious ailment for both patients and the treating ophthalmologists. Recent years have witnessed considerable research in the immunopathogenic mechanism of TED that has resulted in an expansion and modification of the available management options. AIM Purpose of this review is to summarise the advances in the management of thyroid ophthalmopathy. MATERIAL AND METHOD A thorough literature search and of the past 10 years web search with words Thyroid ophthalmopathy, recent, advances. RESULTS Recent VISA classification and new serum markers seem to have potential to give diagnostic as well as therapeutic guidance, gauge treatment response and even identify risk of disease progression. Majority of TED patients can be managed conservatively due to its self-limiting nature but if indicated, still steroids are the preferable medical therapy; however, there is an increasing consensus towards the use of parenteral form as compared to the oral one on account of greater efficacy with lesser side effects. Steroid sparing medications, for example, rituximab, infliximab, etanercept, adalimumab, teprotumumab, tocilizumab, tanshinone, are showing encouraging results and form an area of active research. CONCLUSION Radiation therapy remains as an adjunctive modality in active diseases as a nonmedical treatment for TED with some promising data. Surgical intervention may be required in vision threatening conditions or to counteract the sequel of inflammatory phase. Advances in surgical techniques like stereotactic image-guided balanced orbital decompression with endoscopic approach ensure meticulous dissection with minimal trauma.

Abstract
The literature regarding orbital decompression for thyroid eye disease is vast, spanning multiple specialty areas including neurosurgery, head and neck, maxillofacial, and ophthalmic plastic surgery. Although techniques have advanced considerably over the more than 100 years during which this procedure has been performed, the 4 major approaches remain: transorbital, transcranial, transantral, and transnasal. The explosion in literature related to orbital decompression has mostly involved minor technical variations on broader surgical themes. The purpose of this review is to organize the major approaches in terms of bony anatomy and to contextualize variation in transdisciplinary techniques within a common conceptualization.
