Endonasal endoscopic anatomy of superior orbital fissure: Anatomic study

Introduction:The superior orbital fissure(SOF) is a space connecting the middle cranial fossa and the orbit.It is situated laterally to and below the optic canal between the optic foramen and the foramen rotundum.SOF is bounded by the lesser wing of the sphenoid bone superiorly, by the greater wing inferiorly.The optic strut forms the upper medial border of the ﬁssure.Aims/Objectives:The aim is to describe the anatomical features of the SOF and orbital apex regions from an endoscopic endonasal viewpoint to orient the surgeons.Matherials/Methods:Two human injected cadaver heads were dissected.Dissections were done through endonasal endoscopes (4mm,0degree).Results:The medial aspect of the SOF are exposed.The periorbital layer continues with the dura of the lateral sellar compartment, and the fascial system covering the IOF and the pterygopalatine fossa.The maxillary strut indicating the SOF.The optic strut divides the SOF from the optic canal, while the maxillary strut divides the SOF from the foramen rotundum.Muller"s muscle extends for the IOF passes over the maxillary strut and enters the SOF.Discussion:Description of the endoscopic perspective of the orbital apex and SOF anatomy is needed.Annulus of Zinn is fused to the periorbita along the superior and medial orbital wall at the level of the posterior orbit.The CN III has been described as the closest nerve to the medial rim of the fissure, and the CN IV as the closest one to the superior rim of the fissure.The ophthalmic artery enters the optic canal inferolaterally to the opticnerve.ConclusionEndoscopic approach to SOF is challenging due to close relation of important neurovascular structures and still not in use in clinical settings.Further studies and possibly pioneer clinical applications are necessary.

Comparison of flap and flapless method in patients used with endonasal Dacryocystorinostomy (DSR)

Vergleich der Flap- und Flapless-Methode bei Patienten, die mit endonasaler Dacryocystorinostomy (DSR) verwendet werden

Introduction:. The main method in the treatment of epiphora due to nasolacrimal duct (NLD) obstruction is dacryocystorhinostomy (DSR) surgery. That is why Endonasal DSR has become popular recently. That's why we; We wanted to compare the method with and without flap in patients who underwent endonasal dacryocystorhinostomy (DCR). Materials and Method: Patients who underwent Endonasal Dacryocystorhinostomy (DSR) due to Chronic Dacryocystitis in our center between 2021 and 2023 were divided into two groups. 50 patients underwent flap surgery and 50 patients underwent flapless surgery (removing the flap above the lacrimal bone). Surgical success of patients in the two groups was compared. Results: The average follow-up period of patients who underwent flap application was 17.1±1.2 months, and the average follow-up period of patients who underwent double flap was 18.2±1.8 months. Surgical success is 82% and 96% in the groups where surgery is performed with or without flaps, respectively. There was a difference between the groups in terms of surgical success. (In favor of no flap) (p&lt;0.05) Discussion and Conclusion: In our study, surgical success was found to be higher in patients with Dacryocystorhinostomy (DSR) performed without flaps. Flapless Dacryocystorhinostomy (DCR) can be successfully performed in all patients.Einführung:. Die wichtigste Methode bei der Behandlung von Epiphora aufgrund einer Obstruktion des Ductus nasolacrimalis (NLD) ist die Dakryozystorhinostomie (DSR). Deshalb ist die endonasale DSR in letzter Zeit populär geworden. Deshalb haben wir; Wir wollten die Methode mit und ohne Lappen bei Patienten vergleichen, die sich einer endonasalen Dakryozystorhinostomie (DCR) unterzogen hatten. Materialien und Methode: Patienten, die sich in unserem Zentrum zwischen 2021 und 2023 einer endonasalen Dakryozystorhinostomie (DSR) aufgrund einer chronischen Dakryozystitis unterzogen, wurden in zwei Gruppen eingeteilt. 50 Patienten wurden einer Lappenplastik und 50 Patienten einer Lappenplastik (Entfernung des Lappens über dem Tränenbein) unterzogen. Der chirurgische Erfolg der Patienten in den beiden Gruppen wurde verglichen. Ergebnisse: Die durchschnittliche Nachbeobachtungszeit von Patienten, die sich einer Lappenplastik unterzogen, betrug 17,1 ± 1,2 Monate, und die durchschnittliche Nachbeobachtungszeit von Patienten, die sich einer Doppellappenplastik unterzogen, betrug 18,2 ± 1,8 Monate. Der chirurgische Erfolg beträgt 82 % bzw. 96 % in den Gruppen, in denen die Operation mit bzw. ohne Lappenplastik durchgeführt wird. Es gab einen Unterschied zwischen den Gruppen hinsichtlich des chirurgischen Erfolgs. (Zu Gunsten von keine Klappe) (p&lt;0,05) Diskussion und Schlussfolgerung: In unserer Studie wurde festgestellt, dass der chirurgische Erfolg bei Patienten mit Dakryozystorhinostomie (DSR) ohne Lappenplastik höher war. Die klappenlose Dakryozystorhinostomie (DCR) kann bei allen Patienten erfolgreich durchgeführt werden.No conflict no interest.

The aim of this success is to discuss the studies of endonasal optic nerve decompression performed for different purposes, especially treatment approaches in traumatic optic neuropathy

Introduction: Optic nerve decompression is performed to reduce the pressure in patients whose optic nerve is trapped in the canal or who develop pressure-related loss of function. The aim of this study is to evaluate the effectiveness of endonasal optic nerve decompression performed for different reasons and to discuss treatment approaches, especially in traumatic optic neuropathy. Method: Patients who underwent endonasal optic nerve decompression for different reasons at Ankara University Faculty of Medicine, Department of Ear Nose Diseases between 2018 and 2023 were retrospectively examined. History, examination, pre-post-operative eye examination findings, histopathology results, treatment approaches and follow-up results were evaluated. Patients with missing data were not included in the study. Results: A total of 44 patients, 26 (59%) males and 18 (41%) females, were included in the study. The average age was found to be 42 years old. Twenty-one patients (47%) were operated for tumor, 15 patients (34%) for trauma, 6 patients for pseudotumor cerebri (13%), 1 patient for hematoma (3%), and 1 patient for graves (3%). An improvement in postoperative eye examination findings was observed in fourteen patients (32%), the same pre- and postoperative eye examination findings were observed in 29 patients (66%), and a worsening in postoperative eye examination findings was observed in 2 patients (2%). Conclusion: Today, endonasal optic nerve decompression is successfully applied in many indications. In our study, it was observed that combined treatment approaches gave successful results, especially in traumatic optic neuropathies, and if performed at the earliest possible period, better results could be obtained.The authors declare that there is no conflict of interest
