Giant osteomas of the ethmoid and frontal sinuses ary very rare, with only a few dozen cases reported in the literature. Given their rarity, the clinical characteristics and treatment of this disease remain controversial. In this study, the clinical presentation and surgical methods used to treat three patients with giant osteomas of the ethmoid and frontal sinuses are described, combined with a review of the literature from 1975 to 2011. In total, 45 patients with giant osteomas arising from the ethmoid and frontal sinuses (including the present cases) have been reported in 41 articles. Headache and ocular signs are the most common symptoms. This disease often leads to intracranial or intraorbital complications. The main treatment for giant osteoma is surgery via an external approach. The outcome of surgery for giant osteoma is good, with rare recurrence, no malignant transformation and few persistent symptoms.

Osteomas of the nose and paranasal sinus are common benign tumors that can extend to surrounding structures and result in orbital or intracranial involvement. Presenting symptoms include facial pain, headache, cerebral symptoms, ocular symptoms, and so on, depending on the location and size of the tumor. They commonly occur within the frontal, ethmoid, maxillary, and sphenoid sinuses; however, there are rare cases of reported osteomas in the nasal cavity, turbinate, or orbit. Our case report describes a patient with nasolacrimal duct osteoma who presented with ipsilateral ocular pain, epiphora, and medial canthal swelling. We performed intranasal dacryocystorhinostomy using a nasal endoscope and removed the lacrimal duct osteoma. This report describes symptoms and management of an isolated nasolacrimal duct stone with a review of the literature.

Osteochondroma is a common benign tumor of the axial skeleton, especially in the distal metaphysis of the femur and the proximal metaphysis of the tibia, that can occur on the facial skeleton (albeit rarely). Osteochondroma is differentiated from chondroma, osteochondromatosis and osteoma. Osteochondroma shows an irregular radiopaque lesion and chondromatic area surrounded by the osteoma. When it develops in the long bone, it has a marked tendency to occur at 10 to 20 years of age and ceases with the end of pubertal growth. However, when it develops in the mandibular condyle, it is prevalent in the third decade and continuous to develop. Tumors that develop in the long bone have a predilection for men, but tumors in the mandible have a predilection for women. In osteochondroma of the mandibular condyle, clinical features presented include occlusal changes, facial asymmetry, headaches, pain and joint noise on the temporomandibular joint, mouth opening limitations, and jaw deviation at the involved site. The first choice of treatment for the massive osteochondroma is surgical removal. A 70-year-old female patient with an osteochondroma on her right mandibular condyle visited our clinic. We surgically removed the mass with favorable results. It is presented here along with a review of literature on osteochondroma.

Giant paranasal sinus osteomas are rare tumors that may be very closely adherent to surrounding anatomical structures, and complete removal of these tumors may be very challenging. We report 6 cases of giant paranasal sinus osteomas that were removed completely and discussed their symptoms, diagnostic workup, and our surgical approach. We reviewed the patient files of our 6 cases with giant paranasal osteomas and summarized their history, symptoms, diagnosis, management, and follow-up. Three of our patients underwent endoscopic sinus surgery; the other 2 patients underwent open surgical approach (osteoplastic flap procedure with bicoronal incision), and 1 patient underwent both endoscopic and open approaches, all under general anesthesia. Mean patient age was 42.6 years (range, 18-54 years). Main symptoms were headache, proptosis, and diplopia. Physical examination findings include proptosis and frontal puffiness. Paranasal sinus computed tomography revealed larger than 3-cm-diameter tumors in the frontal and ethmoid sinuses. The surgical approach to each case was customized to the location, size, and presenting symptoms of the osteoma. Histopathology revealed osteoma in all cases. All patients were evaluated with paranasal sinus computed tomography scan postoperatively. At a mean follow-up of 15 months, complication was observed in 1 patient; no residual tumor or recurrence was detected following surgery. In symptomatic cases with huge tumors, open, endoscopic, or combined approaches could be applied because of the location and size of the tumor with successful outcomes. Both endoscopic and open approaches are safe and effective methods for removal of these tumors.

An 18 year old male presented with worsening headaches, pain with ocular movement and swelling that involved the left anterior periorbital and frontal sinus region. Radiographic images revealed a polypoid bony mass of mixed radiodensity extending into the left and right frontal sinuses. Histologic examination of the resection material resulted in the diagnosis of an osteoma with osteoblastoma-like features, an osteoma variant that has zones indistinguishable from an osteoblastoma. The clinical, radiographic, and morphologic features of sino-orbital osteoma with osteoblastoma-like features are discussed.

Osteomas are the most frequently observed benign bone tumors of paranasal sinuses. Although they are generally detected by chance during radiological analyses, they may create severe complications after intracranial extension. While computed tomography findings play a key role to differentiate osteoma from other osseous lesions of paranasal sinus, magnetic resonance imaging identifies extension to surrounding structures and possible complications. Osteoma was detected in a 28-year-old female patient who admitted with complaints of headache and difficulty in breathing. Patient was operated after diagnosis; however, we were unable to remove the mass totally due to its location and size. In this article, we report, to our knowledge, the largest defined osteoma case in the literature to date, with ethmoid sinus origin, orbital, nasal cavity and intracranial extension, accompanied with distinctive computed tomography and magnetic resonance imaging findings.

Meningiomas-en-plaque (MEP) comprise 2.5% of all meningiomas. While they typically arise in the sphenoid wing, convexity MEP are comparatively rare and are often confused with meningeal sarcoidosis, osteoma, tuberculoma, or fibrous dysplasia, with very little information published in the literature. We conducted a literature review on PubMed of English-only articles using a keyword search. All studies that described reports of convexity MEP were reviewed for patient demographics, presenting symptoms, radiological reports, surgical management, recurrence rates, histopathological presentation, post-operative complications, and follow-up. This resulted in 12 papers comprising 22 cases of convexity MEP. Seventeen (77%) of the 22 patients were female with an average age of 53.2years. Intitial presenting symptoms included headache in 12/20 (60%), hemiparesis in 5/20 (25%), and visual symptoms in 1/20 (5%). Of the 14 patients who underwent surgical resection, only four were reported as gross total resection. Twelve reports had associated pathology reports, with all 12 tumors graded as World Health Organization Grade I. Convexity MEP, while rare, present a challenge with regard to correct diagnosis and subsequent resection. The easier accessibility of these meningiomas predicts higher surgical success rates and incidence of total resection, though care must be taken to ensure gross total removal of tumor, dural attachments, and any overlying hyperostotic bone. Though hyperostosis is frequently observed with this variant of meningioma, it is neither exclusive nor wholly indicative of MEP. Due to its rarity in both clinical practice and the literature, further studies are warranted to identify modern imaging means to correctly diagnose this condition.

We present a case of a subdural osteoma. A 29-year-old female presented with a 3-year history of headaches. Computed tomography scan revealed a homogeneous high-density lesion isolated from the inner table of the frontal bone (a lucent dural line) in the right frontal convexity. Magnetic resonance imaging revealed an extra-axial lesion with a broad base without dural tail sign and punctate enhancement pattern characteristic of abundant adipose tissue. Upon surgical excision, we found a hard bony mass clearly demarcated from the dura. The mass displayed characteristics of an osteoma upon histological examination. The symptom was relieved after operation.

Osteomas grow slowly, blocking or compressing adjacent structures, and frequently causing aesthetic deformity. Although most patients remain asymptomatic, development of facial pain and headaches due to compression of adjacent sensory nerves is not uncommon. Depending on the location of osteoma, many techniques were introduced to remove it. If the osteoma was located close to important structures such as nerves and vessels, surgeons can be concerned about damaging them resulting in unfavorable symptoms to patients. Osteoma is a benign slow-growing osteogenic lesion, composed of well-differentiated mature bone tissue, characterized by the proliferation of compact or cancellous bone, and found in the head and neck region. It is often slow growing and asymptomatic, diagnosed incidentally on radiographs. It can cause deformation of the bone and compression of the adjacent structures such as nerve compression. This case shows how symptomatic osteoma can be successfully extracted.

Intracranial osteomas completely unrelated to osseous tissues are extremely rare. In the present study, the case of a 40-year-old female who presented with persistent headache is reported. Computed tomography (CT) and bone window CT revealed an ossified lesion in the frontal area. Fast imaging employing steady-state acquisition (FIESTA)/CT venography fusion imaging demonstrated that the mass was located just below the superior sagittal sinus and cortical veins, and had adhered partially to these veins. Surgery achieved complete tumor removal with preservation of the cortical veins and superior sagittal sinus. The histological examination findings were compatible with osteoma. The present postoperative course was uneventful. The present rare case of intracranial osteoma originating from the falx was successfully treated surgically. Preoperative FIESTA/CT venography fusion imaging was very useful to demonstrate adhesion between the tumor mass and the superior sagittal sinus and cortical veins.
