The sphenoid bone has a specific development during fetal life, until it reaches its complete dimensions. The sphenoid cavities are usually undeveloped at birth and they reach their full volume only after puberty. Pneumatization of the sphenoid sinus is unpredictable and different for each person.The authors do not intend to develop a literature review or to compare their experience with data already published. The paper is not an original imagistic study of the authors, it only represents a short communication on the imagistic anatomy of the sphenoid sinus, in order to avoid complications during surgery in the area.Based on their patients own CT-scan examination, the authors try to classify the anterior, lateral and posterior extensions in close connection with the surgical endoscopic approach of the sphenoid sinus.
Abstract. Choanal atresia is the most frequent nasal congenital malformation, which, depending on the unilateral or bilateral location, has a different symptomatology. The diagnosis is confirmed through the patient's medical history, nasal endoscopy and imagistic examination (computed tomography). The treatment is surgical and aims the (fibrous and bone) tissue disintegration which blocks the choana, and is performed through endoscopic surgical techniques. The blocked area is maintained functional by mounting a stent at the choanal tunnel level. The authors aim to describe their own experience regarding both the diagnoses as well as the treatment of this pathology, the results being compared to those from the quoted literature. The surgical technique differs depending on the type of choanal atresia: bone or membranous. The duration to maintain a fix position of the stent and the material used for the stent represent the variables which provide the success of the endoscopic surgical intervention of the choanal atresia. Subsequently, the patient is followed up at 2, 6, 12 months in the first year and then annually until 18 years of age. Choanal atresia is solved through endoscopic surgical techniques by mounting a silicone stent which shall be maintained in position for a minimum period of 3 months. The endoscopic approach of the unilateral choanal imperforation is the method of choice with minimum complications, increased success rate and fast recovery.
The authors present a case of recurrent frontal rhinosinusitis, for which the drug therapy was ineffective. To avert the risk of complications, multiple classic and endoscopic surgical procedures were performed on the frontal sinus pathology. The bacterium involved in this form of rhinosinusitis was represented by a Methicillin-resistant Staphylococcus aureus (MRSA) diagnosed during the first endoscopic approach (the second surgical procedure) for which the treatment corresponding to the antibiogram was followed. At the last hospitalization, the patient has underwent a frontal bilateral drainage surgery (modified Lothrop procedure) and started an adequate anti-MRSA treatment. The authors wondered whether multiple recurrences of frontal rhinosinusitis are determined by an incomplete drainage, by a persistent infection with MRSA or by both.
The paranasal sinus osteoma is a benign tumor characterized by a slow growth rate. Initially, the symptoms are uncharacteristic in most of the cases, afterwards they can cause headaches, nasal obstruction, epiphora etc. The authors present the case of a 45-year-old patient from IFACF - ENT “Prof. Dr. D. Hociota” with a history of frontal headache and retrobulbar pain, which started about 6 months ago. The endoscopic and computer tomographic exam mark the presence of a left frontoethmoidal tumor with bone consistency. The surgical approach was combined, with the complete macroscopic removal of the tumor and ensuring the physiological frontal sinus drainage.
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.
