Osteomas are among the most common benign tumors of the paranasal sinuses. Symptomatic osteomas are most often found in the frontal recess and the frontal sinus. While the extranasal approach is still a part of the treatment concept for removing osteomas at this localization, over the last years the endoscopically controlled endonasal approach has greatly gained in importance due to the improved surgical equipment. We retrospectively analyzed the surgical indication, surgical approach and outcome of the removal of osteomas of the frontal recess and the frontal sinus performed at our hospital between 1996 and 2010. The exact surgical technique, intra- and postoperative complications, the duration of the hospital stay and the follow-up and subjective contentment of the patients were evaluated. With a total of 24 patients being included, the study comprises one of the largest groups of patients with osteomas of the frontal recess and sinus. Over the study period, the frequency of the endoscopic approach

This GHOW represents a case of an uncommonly reported neoplasm in birds that was appropriately treated but that resulted in a lack of regrowth of secondary covert and flight feathers and a loss of flight ability. Osteomas are discrete and space-occupying neoplasms composed of mature lamellar bony trabeculae arising from cortical bone, periosteum or soft tissues.3 7 Osteomas are rare in animals and have been reported infrequently in birds.2-8 11-24 A single case report of an osteoma-like tumour arising from the proximal radius in a barred owl is published; however, the histological description of the lesion is not consistent with a classical osteoma, and the bird was euthaniased due to the extent of the lesion with no attempt at surgery or rehabilitation.10 The authors could not find reports of an osteoma in a free-living bird or in any raptor species.. In most mammals, osteomas typically arise from the skull, especially the oral cavity and nasal and paranasal sinuses, while in humans, these ...

Strictly defined, osteoma cutis refers to the presence of bone within the skin in the absence of a preexisting or associated lesion. This is opposed to secondary types of cutaneous ossification that can occur in reaction to inflammatory, traumatic, and neoplastic processes.

Osteoma of paranasal sinuses is a rare benign tumour arising from the proliferation of compact or cancellous bone. They are more common in frontoethmoidal region where as osteomas of sphenoid or maxillary region are rare. These tumors may be incidentally detected on radiographs, or may grow to produce symptoms if extends into orbit or skull base. We present here a rare case of large osteoma of the maxillary antrum and ethmoidal sinus in a 60-year-old man which was removed using combined endoscopic and external approach.. ...

Osteomas are benign, slow-growing osteogenic tumors commonly occurring in the craniofacial bones. Osteomas are characterized by the proliferation of compact and/or cancellous bone. It can be of a central, peripheral, or extraskeletal type. The peripheral type arises from the periosteum and is rarely seen in the mandible, if involved, the lingual surface and lower border of the body are the most common locations of these lesions. They are usually asymptomatic and can be discovered in routine clinical and radiographic examination. This paper presents a large solitary peripheral osteoma located in the lingual surface of the right posterior mandible. The osteoma was removed surgically, and no recurrence has been observed. ...

ABSTRACT. Four horses were presented to the Onderstepoort Veterinary Academic Hospital with histories of facial asymmetry, nasal discharge or obstruction of normal nasal passage airflow. Radiographic examination of the maxillary sinuses of 2 cases revealed well circumscribed, unilateral, mineralised masses; the other 2 cases showed less mineralisation. The masses were accessed for further investigation by surgically created frontonasal bone flaps or trephination of the maxillary sinuses. Diagnosis of osteoma was confirmed histopathologically in 3 of the cases and of ossifying fibroma in the 4th. Two horses were euthanased directly after surgical intervention due to poor prognosis. Osteomas are by nature expansile tumours andfollow the complex communication of the sinuses, and therefore are not all amenable to surgical removal. Osseous fibromas are large, solitary, expansile lesions that are rare in all species but reported most frequently in horses. They have an apparent predilection for the ...

Objective: Disorders caused by impairments in the parathyroid hormone (PTH) signalling pathway are historically classified under the term pseudohypoparathyroidism (PHP), which encompasses rare, related and highly heterogeneous diseases with demonstrated (epi)genetic causes. The actual classification is based on the presence or absence of specific clinical and biochemical signs together with an in vivo response to exogenous PTH and the results of an in vitro assay to measure Gsa protein activity. However, this classification disregards other related diseases such as acrodysostosis (ACRDYS) or progressive osseous heteroplasia (POH), as well as recent findings of clinical and genetic/epigenetic background of the different subtypes.

Abstract The case of a relatively frequent benign osteoblastic tumour, osteoid osteoma at an atypical site is presented. It was in a 20 year old man who attended the outpatient department of Aga Khan University Hospital, Karachi with pain in left groin since last 6 months which often occurred at night and was relieved by taking NSAIDs. X-ray failed to reveal the cause. CT scan showed central radiolucent nidus with surrounding sclerosis suggestive of osteoid osteoma in the left acetabulum. Acetabulum is a rare site for osteoid osteoma, the usual sites are diaphysis of long bones. Hence, the diagnosis is often difficult and delayed in such cases. CT scan, Bone scan and MRI, helped in diagnosing the condition. Resection of the lesion by open technique under fluoroscopic control was performed and histopathology confirmed the diagnosis.

Osteoid osteomas are benign bone neoplasms that may cause severe pain and limit function. They are commonly treated by radiofrequency ablation (RFA) through a needle inserted into the nidus of the lesion under CT guidance, which is associated with exposure of young patients to relatively high dose of radiation. The objective of this study was to investigate the amount of radiation, effectiveness and safety of an alternative imaging approach, the 3D image-guided (O-arm) technology and the Stealth navigation. We retrospectively reviewed 52 electronic medical files of patients (mean age 24.7 years, range 8-59 years) who were treated with thermal ablation of benign osteoid osteomas guided by the navigated O-arm-assisted technique in our institution between 2015 and 2017. Data were extracted on the associated complications, the reduction in pain at 3 months and one year postoperatively, and the amount of radiation administered during the procedure. The level of pain on a visual analogue scale decreased from

Scoliosis caused by osteoid osteomas are typically non-flexible curves where the osteoid osteoma occurs on the concavity of the curve. While peripheral osteoid osteomas, far away from the neural elements CAN be treated with radiofrequency ablation, treating osteoid osteomas of the spine with RFA needs to be done on a case by case basis - depending on how close the lesion is to the neural elements. Osteoid osteomas can occur in either the vertebral body or the posterior elements of the spine, but typically occur in the posterior elements. Histologically, osteoid osteomas of the spine are identical to those in the extremity. ...

Osteoid osteoma comprises 4% of all bone tumors. It is a benign tumor that is most frequently observed on the proximal femur and tibia. In the literature, there is limited data about osteoid osteoma on the ulnar head. We report a 29-year old male with osteoid osteoma on the ulnar head. This male patient presented with swelling and persistent pain on the ulnar side of his right hand. There was a history of falling two years ago, after which the pain had increased. The patient was diagnosed as triangular fibrocartilage complex (TFCC) injury, and medical treatment was initiated. Then, following clinical and radiological workup, with the preliminary diagnosis of osteoid osteoma, surgical excision was performed. After surgical excision, the diagnosis was confirmed with a histopathological examination. Although it is a rare localization, osteoid osteoma on the ulna head should be kept in mind in patients with ulnar-sided wrist pain.. Key words: Osteoid osteoma, ulnar head, wrist pain ...

Osteoid osteoma (OO) is a benign bone tumor, with a male-female ratio of approximately 2:1 and mainly affecting long bones. Ten percent of the lesions occur in the spine, mostly within the posterior elements. Treatment options for OO include surgical excision and percutaneous imaging-guided radiofrequency ablation (RFA). Lesions within the spine have an inherent risk of thermal damage to the vital structure because of proximity to the neural elements. We report a novel use of the epidural catheter for air injection for the neuroprotection of nerves close to the OO of the spine. A 12-year-old and 30 kg male child with an OO of the L3 vertebra was taken up for RFA. His preoperative examinations were within normal limits. The OO was very close to the L3 nerve root. Under general anesthesia, lumbar epidural catheter was placed in the L3-L4 space under imaging guidance. Ten ml of aliquots of air was injected under imaging guidance to avoid injury to the neural structures due to RFA. The air created a gap

Ivory exostoses represent a type of osteoma that affects bones formed by membranous ossification, chiefly affecting calvarial and mandibular surfaces2,4,6,10-12,20,22,28 (Fig. 21-2). Multiple osteomas of this type are frequently associated with colonic polyposis and fibrous soft tissue tumors, including mesenteric fibromatosis and epidermal inclusion cysts in the familial disorder known as Gardners syndrome.13,14,17,24,29 Some patients also had distinct hyperplastic changes of the retinal pigmented epithelium.22,32,33 The development of ocular lesions may precede the development of colonic and osseous manifestations. The polyps of the gastrointestinal tract are adenomatous and typically involve the colon but can also be present in the duodenum and stomach. The adenomatous polyps of the gastrointestinal tract have a high propensity for malignant transformation. In fact, colon cancer develops in all affected individuals unless prophylactic colectomy is performed.23 The disorder is transmitted by ...

Gardner syndrome is a genetic disorder characterized by multiple intestinal polyps, dental abnormalities, multiple osteomas, and mesenchymal tumors.

Background. Traditional open surgery for frontal sinus pathology and cerebrospinal fluid (CSF) leaks is complex and involves a craniotomy. Minimally invasive options offer an alternate solution. We describe and assess the outcome of a minimally invasive approach for lesions and defects involving the frontal sinus. Methods. The technique introduces an endoscope via a small frontal sinusotomy accessed via a small medial brow incision. This allows excellent visualisation of the frontal sinus. Fine thin-shafted instruments traditionally used during tympanoplasty or pituitary surgery are passed through the sinusotomy together with an endoscope for dissection and tissue excision. This technique can be combined with conventional endonasal surgery. Results. We describe the use of this technique in three patients: A fracture of the posterior table of the right frontal sinus with CSF leak, a right frontal sinus osteoma and a right frontal sinus mucocoele. Symptom resolution occurred in all patients and no short

Pain may be relieved by nonsteroidal anti-inflammatory drugs.. Treatment varies based on the health of the patient. If he/she is otherwise healthy and is not significantly bothered by the pain, the tumor is treated symptomatically with anti-inflammatories. If this therapy fails or the location of the tumor could lead to growth disturbances, scoliosis, or osteoarthritis, surgical or percutaneous ablation may be considered.[10] If surgery is preferred, the individual may be referred to a podiatrist or an orthopedic surgeon to perform the procedure. Post-surgery therapy and strengthening may be needed, depending on the tumor location and health of the individual. While shown to be effective, surgical resection has many potential complications, including difficult intraoperative identification of the tumor, local recurrence from incomplete resection, and resection of weight bearing bone that can necessitate prolonged hospital stays and complicate recovery.[11]. Recently, CT guided radiofrequency ...

Captivity predisposes elephants to a variety of medical problems, some of which can be found to a lesser degree in wild elephants. Example of these conditions include specific foot problems, skin diseases, and dental abnormalities. Two of the most common dental disorders of elephants in captivity are impacted or mal-positioned molar teeth and abraded, split, fractured, and infected tusks. The former is most commonly seen inAsian elephants. These two types of dental disorders occur most commonly because of the elephants unique dentition and may be exacerabated by inappropriate husbandry techniques. Siri, a 35 year old female Asian elephant at the Rosamond Gifford Zoo at Burnet Park, has developed malaligned right and left upper molars which are medially rotated. It is currently believed that this disorder is, in part, due to having less browse to help wear down her molars. However, the alignment of the molars could also be affected by an osteoma that is developing within her left nasal passage ...

I had a right frontal craniotomy for a 1.5 cm colloid cyst in 2001. They couldnt remove it because it was attached to a vein, so they decided to drain it to relieve my severe hydrocephelus. Post-op it looked like a deflated balloon on MRI. In April 2009, I had an MRI after seeing a doctor about a different matter. He took my history and asked when my last MRI was, I told him I hadnt had one since about 2 years post-op. Anyway, the colloid cyst was back to its original size but no
