Orbital fractures may be accompanied with severe damage of the eye bulb and other intraorbital tissues. Early clinical findings can be very mild, therefore it is vital to actively seek not only for any damage done to the soft tissues of the orbit, but also for extraorbital complications such as liquorrhea or meningitis. We report a relatively rare case of blow-in fracture of orbital roof in eleven years old boy. Patient was admitted to the emergency care after falling off a bicycle without impaired consciousness. During admission ophthalmologist evaluated the condition as severe contusion of the left bulb, with hemophthalmia and retinal comotosis. Due to significant swelling of eye lids and periorbital hematoma, it was not possible to perform specific tests to objectify possible oculomotor disorder and diplopia. CT scan findings show dislocated fracture of orbital roof with fragments reaching into the musculus rectus superior. For high risk of bulbus penetration and muscle damage a surgical intervention with bone fragments removal was performed using endoscopic assisted frontal orbitotomy. After operation patient had no signs of functional eye disorder.
Passage of nasal airflow during breathing is crucial in achieving accurate diagnosis and optimal therapy for patients with nasal disorders. Computational fluid dynamics (CFD) is the dominant method for simulating and studying airflow. The present study aimed to create a CFD nasal airflow model to determine the major routes of airflow through the nasal cavity and thus help with individualization of surgical treatment of nasal disorders. The three-dimensional nasal cavity model was based on computed tomography scans of the nasal cavity of an adult patient without nasal breathing problems. The model showed the main routes of airflow in the inferior meatus and inferior part of the common meatus, but also surprisingly in the middle meatus and in the middle part of the common nasal meatus. It indicates that the lower meatus and the lower part of the common meatus should not be the only consideration in case of surgery for nasal obstruction in our patient. CFD surgical planning could enable individualized precise surgical treatment of nasal disorders. It could be beneficial mainly in challenging cases such as patients with persistent nasal obstruction after surgery, patients with empty nose syndrome, and patients with a significant discrepancy between the clinical findings and subjective complaints.
Isolated sphenoid fungal sinusitis is a relatively rare disease with non-specifi c symptoms. The most common symptom is headache and the typical symptoms of sinusitis may be completely absent. A CT examination with specifi c radiological signs plays an important role in the diagnostic process but the defi nitive dia gnosis is determined by a histological examination. Due to the location of the sphenoid sinus, in some cases, the delayed dia gnosis may cause serious consequences. The article presents a case report of a patient with isolated mycotic infl ammation of the sphenoid sinus. The aim of the article is to point out the non-specifi c symptoms of the disease and the typical radiological signs that can help us in the dia gnostics. Key words mycotic infl ammation – sphenoid sinus – headache
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.
