Osteomas are benign mesenchymal tumors, characterized by proliferation of compact or modularly bone. They are small, slow-growing lesions, usuallyasymptomatic and detected in young adults. This tumors can affect the paranasal sinuses and are often diagnosed with incidental findings through imaging tests. Osteomas are typically restricted to the craniofacial skeleton and rarely foundin other bones. Osteoma of the gnathic bones may be peripheral or endosteal.The osteomas’ etiology is controversial and still unknown. It is more frequent in the frontal sinuses, corresponding to 57% of the paranasal sinuses osteomas, followed by the ethmoidal and maxillary sinuses. Computed Tomography (CT) is the gold standard to assess the location, extent, and aspects of the injury. The objective of this paper is to present a case report of osteoma diagnosed by computed tomography (CT) scan, indicating the importance of the technology of imaging in the medicine diagnostic.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract (1%). These tumors express the CD 117 in 95% of cases. The stomach is the preferential localization (70%). Diagnosis is difficult and sometimes late. Progress of imaging has greatly improved the management and the prognosis. Computed tomography (CT) is the gold standard for diagnosis, staging, and treatment follow-up. The increasing recognition of GIST’s histopathology and the prolonged survival revealed some suggestive imaging aspects. Key words: gastro-intestinal stromal tumors; computed tomography; diagnosis

Cemento-ossifying fibroma is a well-bordered, slow-growing, benign fibro-osseous disease. Although its localization is generally in the mandible, it can be seen in any area of the craniofacial region. Radiology and histopathology help to diagnose the condition. Treatment is based on close observation and/or surgical excision. In this case, we report the case of a 62-year-old male patient who had a large radiological appearance, cemento-ossifying fibroma in the paranasal sinuses.

Osteomas are bone tumours arising from the cortical or medullary bones of craniofacial skeleton. Involvement of frontal bone and paranasal sinuses is more frequent than jaw bones. Jaw osteomas are slow growing benign lesions, which are usually asymptomatic or present as painless swelling. Those involving mandibular condyle are relatively rare and result in significant functional and aesthetic disturbances. This paper reports a case of solitary central compact osteoma of mandibular condyle in an adult Indian female patient. A comprehensive review of previously published reports is also presented.

Introduction: Osteomas are the most common, benign neoplasms of paranasal sinuses. Those tumors are often diagnosed accidentaly, during the head imagining procedures. Objective: Clinical and epidemiological assessments of patients with head and neck osteomas. Material and methods: We carried out the analysis of medical documentation of patients treated in Otolaryngology Clinics of MUG in years 2012-2019 with osteoma diagosis and analysed the treatment and its outcome. Results: 38 patients with osteoma have been operated on during the investigated period of time (18 men, 20 women). Most of the osteomas were localized in the area of frontal sinuses (34%). It has been proven that there is no link between this neoplasm and age, sex or tobacco smoking. Conclusions: Osteomas are rare bone neoplasms and constitute less then 1% of all of the head and neck neoplasms. Osteomas cause intense headaches, which are difficult to treat. Diagnostics of such tumors is based on Computed Tomography and surgery is in this case a treatment of choice.

ABSTRACT Foreign bodies in the paranasal sinuses after critical accidents are rare occurrences that have sporadically been reported worldwide. Firearm projectiles, daggers, knives, glass fragments, stones, teeth, and wood can get lodged in the soft and hard tissues of the face. The management and prognosis in these cases depend on the composition and location of the foreign body as well as on the presence or absence of infection. Although there are reports involving the soft tissues of the face, the ethmoid, sphenoid, frontal, and maxillary sinuses are the most frequently involved sites. The main manifestation of this condition is sinusitis arising from infection and/or inflammation caused by the foreign body, which is a contaminated object. We report a case of removal of a firearm projectile located in the maxillary sinus of a 34-year-old patient under local anesthesia.

Abstract Osteomas are slow-growing tumors of the paranasal sinuses, usually found in the frontal and ethmoidal sinus. In many cases, these tumors are discovered by chance or after an imagistic exam for a non-responsive to medical treatment headache. In asymptomatic tumors, conservative treatment is indicated, while in big tumors with complications the gold standard is surgical resection of the tumor. We present two cases of rather similar anterior ethmoidal osteomas in which the therapeutic management was decided according to the symptomatology of the patient and the imagistic CT exam. We decided different ways of treatment for the two cases based on the CT scan, which has a major role in predicting intraoperative complications during endoscopic sinus surgery.

An A-scan ultrasound gives us one dimensional information about the area of interest in the body being examined. Paranasal sinuses are empty air-filled cavities whose functions are to support the weight of the skull, introduce resonance to voice and condition the respired air. They are located in the nasal cavity -maxillary sinuses, above the eyes-frontal sinuses, between the eyes -ethmoidal sinuses and behind the ethmoids- sphenoidal sinuses. The objective of our project is to design an A-mode ultrasound system for the detection of paranasal sinusitis, primarily maxillary sinus. The existent conventionally used methods for detection of paranasal sinuses are the X-ray and CT methods. This amounts to large radiation dose every time the patient undergoes an examination and is more expensive. The reasons behind choosing to use the ultrasound method are that it is relatively inexpensive and can be made portable. It is safe as no ionizing radiation is used. Since the ultrasound technique has limited bone penetration which restricts its use to maxillary sinuses alone.

Sphenoid Sinusitis

Acute isolated sphenoid sinusitis is a rare and is seen in only 3% of all cases of all sinusitis. It is frequently misdiagnosed because of its vague clinical presentation. We report a case of 35year old female who presented to our emergency department with complaints of painless rapidly developing bilateral vision loss. Non contrast computed tomography of paranasal sinuses showed only mild opacification of sphenoid sinus. Endoscopic sphenoidectomy was performed within 4 hrs of presentation. After 48 hrs of surgery the patient vision returned to 6/6 bilaterally. Acute sphenoid sinusitis should be considered in the differential diagnosis of acute vision loss. Awareness, early diagnosis, astute clinical sense and emergent intervention can prevent permanent complication.DOI: http://dx.doi.org/10.3329/jom.v15i2.20700 J MEDICINE 2014; 15 : 146-148

SUMMARY The paranasal sinus mucocele is an epithelized cystic lesion containing fluid and is characterized by non-neoplastic expansion of the paranasal sinus due to its capacity to erode the overlying bone. Etiology of these lesions is still under debate. In this report, we described a case of a patient with frontal recess mucocele, associated with contralateral frontal recess osteoma. A 55-year-old man was admitted to the Department of Otorhinolaryngology of our hospital with the complaints of a headache affecting the fronto-ethmoidal region, left-sided nasal obstruction, and postnasal discharge. Computed tomography (CT) scan of the paranasal sinuses showed a dense bony lesion in the left and a cystic hypodense mass in the right-sided frontal recess. The patient was treated surgically, with a combined endoscopicexternal approach, bilaterally. Histopathological examination showed that the wall of the cyst was mucocele, and the bony formation was osteoma. The frontal recess osteoma is regarded as the primary condition. Thus, better ventilation and drainage of the frontal sinus were reestablished.

Rhinolithiasis is a rare pathological phenomenon, according to statistics, the incidence of rhinolith is about 1 person per 10,000 otolaryngological outpatients. Often, rhinolith is accompanied by an asymptomatic course and often becomes an accidental finding. Lack of vigilance of the otorhinolaryngologist and neglect of the possibility of using computed tomography of the paranasal sinuses, first of all, at the first stage of the patient’s treatment in an outpatient setting, often leads to an untimely diagnosis of this disease. Meanwhile, late diagnosis of rhinolith can lead to the development of purulent processes, dystrophic and atrophic changes in the nasal mucosa, naso-oral fistulas, dacryocystitis, osteomyelitis and the formation of an epidural abscess. The article presents a case of prolonged (more than 22 years) presence of a foreign body in the nasal cavity in a 26-year-old female patient, which led to the formation of rhinolith. Despite the long-term complaints and clinical manifestations of the disease with constant visits to the otorhinolaryngologist, the patient did not undergo computed tomography of the paranasal sinuses. The prescribed instrumental examinations (CT scan of the paranasal sinuses and endovideoscopy of the nasal cavity) at the Saint Petersburg Research Institute of Ear, Throat, Nose and Speech allowed us to diagnose rhinolitis of the nasal cavity and successfully carry out surgical treatment.
