Removal Of Orbital Foreign Body Research Articles

Apport des aides technologiques dans l’extraction des corps étrangers orbitaires

Background: Removal of orbital foreign bodies is a surgical challenge. The purpose of this study is to report our experience in the removal of orbital foreign bodies and to evaluate the usefulness of various technological aids in their removal.Materials and Methods: We conducted a single-center retrospective study at Nice University Hospital (France) from January 2017 to December 2023. All patients undergoing surgery for an orbital foreign body during the study period were included. Data recorded included the nature of the orbital foreign body, its size, location, surgical route, outcome (success, partial success, failure), and technological aids used (intraoperative navigation, intraoperative imaging scope, orbital magnet). Concurrently, we designed a dedicated orbital magnet, which was tested in the anatomy laboratory and in two of our patients.Results: Six patients, all young men, were included during the study period. Removal was successful, partially successful, or unsuccessful in one-third of cases, respectively. Failure was associated with orbital foreign bodies located in the intraconal or posterior orbital space. Preoperatively, the use of a “low-artifact” scanner allowed us to better determine the exact size and shape of the orbital foreign body. Intraoperative navigation was not accurate enough, due to the mobility of the orbital bodies within the orbital fat. In our experience, intraoperative scope imaging was more accurate. The use of a dedicated orbital magnet was successfully tested in the anatomy laboratory and allowed the removal of a small orbital foreign body in one of our patients. Intraoperative surgical videos are provided.Conclusion: Vegetal orbital foreign bodies must be systematically removed. Removal of non-vegetal orbital foreign bodies should be considered on a case-by-case basis based on their size, best assessed using a “low artifact” scanner, their location, and their intrinsic ferromagnetism. Intraoperative navigation does not appear useful, while intraoperative scope imaging does. A dedicated orbital magnet might be helpful in removing ferromagnetic orbital foreign bodies. However, an orbital magnet may be ineffective in removing intraorbital bullets, since they are made primarily of an alloy of copper and lead.

Intraorbital Foreign Body With Intracranial Extension: A Case Series

Intraorbital foreign body with intracranial extension is a potentially devastating condition leading to blindness and even death in certain circumstances. Lot of controversies still exist regarding the most appropriate approach for removal of orbital foreign body with intracranial extension. In this paper we have discussed a series of 3 cases where the foreign body was removed through the anterior (transorbital) approach.

Orbitoethmoid Metallic Foreign Body

ABSTRACTIntraorbital foreign body extending to sinuses is rare; often such cases are associated with multiple ocular and orbital morbidities. Retained organic foreign bodies can cause severe inflammation and are detected earlier, whereas inorganic foreign bodies are inert and well tolerated except copper. The management of posteriorly located orbital foreign bodies is a therapeutic dilemma. We report an unusual case of posterior orbital foreign body extending to the ethmoids and sphenoid sinus exclusively removed by transnasal endoscopic approach. Transnasal endoscopic approach can be used as an effective and efficient approach for the removal of orbital foreign bodies lodged on the medial side of the orbit. This approach is recommended in all the cases of foreign bodies in the craniofacial region provided that it is approachable through endoscope and expertise and facilities are available.How to cite this articleBelsare G, Nair AS, Sakhale S.

Problems in diagnosis and treatment of orbital foreign body-an analysis of 24 cases

To evaluate the problems presented in the diagnosis and treatment of orbital foreign body. This was a retrospective case series. We reviewed and analyzed 24 cases of orbital foreign bodies treated by us in the past 5 years. Twenty four orbital foreign body cases were treated by the authors from May 2002 to May 2007. Eleven cases were plant foreign bodies, 6 cases were metallic foreign bodies, 2 cases were glass foreign bodies and 5 cases were other types of foreign bodies. Wound cleaning operations were performed in 18 cases. Foreign body removal surgery was performed in 12 cases. In 7 cases, three or more operations were undertaken. The problems presented in the diagnosis and treatment of orbital foreign body included: (1) History taken was inadequate and failed to recognize the presence of orbital foreign body. (2) The necessary CT examination was not performed. (3) CT films was not read correctly and failed to detect the orbital foreign bodies. (4) An exploration operation was not performed during the emergency operation and subsequent operation for draining of pyogenic infection. (5) Only part of the wood or plastic fragments were removed during the operation. (6) Foreign bodies could not be extracted or were pushed deeply due to unfamiliar with the structure of the orbit, lack of adequate surgical skills or absence of necessary instruments. (7) A second CT examination was not performed and foreign body was not re-localized before the second surgery. (8) An inappropriate anesthesia method were selected (such as using local anesthesia instead of general anesthesia) so that the patient could not stand the painful operation. Many problems presented in the diagnosis and treatment of orbital foreign body, including the handling of the structure of the orbit, correct reading of CT imaging and diagnosis of orbital foreign body, well-informed operative approach, increasing the removal of orbital foreign body and decreasing the complications, these should be focused by ophthalmic surgeons.
