Intraorbital organic foreign bodies pose a diagnostic and management challenge to ophthalmologists. A high degree of suspicion of an orbital foreign body is needed when patients present with injuries to the eyelids and orbit. We present a case of retained intraorbital wooden foreign body which was initially undetected. A 10-year-old boy presented to the eye casualty with signs and symptoms suggestive of orbital cellulitis. He was started on intravenous antibiotics and urgent CT of the orbits did not reveal any foreign bodies. There was spontaneous extrusion of a wooden foreign body through the upper lid two days later, followed by spontaneous resolution of symptoms. Wood has a density similar to air and fat and can be difficult to distinguish from soft tissue in both a plain X-ray film and a computed tomogram. Clinicians should be alerted to the possibility of retention of an intraorbital foreign body in all patients presenting with periorbital trauma. The clinician should also obtain a careful history of the type of injury and should examine the patient in detail. In cases where a wooden foreign body is suspected, investigation by magnetic resonance imaging is preferred.
Background: Mental foramen (MF) is an important landmark to facilitate surgical, local anaesthetic and other invasive procedures. The present study was aimed to provide anatomical information on the position, morphological variations and incidence of mental foramen and accessory mental foramen.Methods: This study was conducted on 41 dry adult human mandibles in the department of anatomy, Government Medical College Srinagar, Jammu and Kashmir. Parameters like incidence, position, shape and presence of accessory mental foramen were studied.Results: Mental foramen was present bilaterally in all 41 mandibles. Accessory mental foramen(AMF) was present in 2 cases (4.87%). The most frequent position of foramen in relation to the teeth was in line with the longitudinal axis of 2nd premolar on both right (63.42%) and left (60.98%) side. Most common shape was round shape.Conclusions: Mental foramen variation often remains unnoticed and undiagnosed. Variations do exist in the position, shape, and size of mental foramen in different population groups. Present study provide the necessary data of mental foramen location and morphometry which may be useful for the surgeons, anaesthetists, neurosurgeons and dentists to carry out nerve block and surgical procedures.
Pneumatization of the sphenoid sinus is highly variable and it depends on the position of the sinus in relation to the sella turcica. The pattern of pneumatization of sphenoid sinus significantly affects safe access to the sella. Pneumatized sphenoid sinus may distort the anatomical configuration so if unaware, accidental injury can occur during invasive surgical technique.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
