Advanced paranasal sinuses osteomas: a retrospective multicentric analysis on surgical management outcomes and intra- and postsurgical complications. This study examines the management and outcomes of large paranasal sinus osteomas (PSO), especially those abutting or encasing critical structures of the skull base and orbit. A multicentric retrospective analysis was conducted between June 2007 of PSO to the cribriform plate. Long-term complications were more frequently observed in cases involving the anterior and posterior plate of the frontal bone. This study highlights the complexities involved in managing large PSO, demonstrating that size and anatomical relationships of these osteomas can critically influence surgical decisions, residual disease, and complication rate. The study's
Canine tooth syndrome after frontoethmoidal osteoma surgery: a case report. : Canine tooth syndrome is a rare condition defined by the simultaneous presence of superior oblique palsy and Brown syndrome, resulting from pathological changes in the trochlear region. This syndrome can develop through various mechanisms, including dog bites, head trauma, infections, inflammation, and scarring . This report highlights its occurrence following sinus surgery for the first time. s: Medical and surgical records of an 18-year-old girl who presented with reading position diplopia after sinus surgery for right-side frontoethmoidal osteoma were retrospectively reviewed. : Strabismus examination revealed 8 Prism Diopter (PD) primary position hypertropia in the right eye that increased to 20 PD in downgaze
Bilateral choroidal osteoma: long-term follow-up of secondary choroidal neovascularization in a child using antiangiogenic therapy. Choroidal osteoma is a rare condition, and its treatment is not well established, especially in the pediatric population, where use of antiangiogenics for choroidal neovascularization is poorly studied. Few studies have reported the long-term follow-up of pediatric patients with bilateral choroidal osteomas. We report the case of a girl who was diagnosed at the age of 3, with the appearance of bilateral secondary choroidal neovascularization, and has been under strict observation for 12 years. The effectiveness of antiangiogenic agents as a long-term therapeutic option for secondary choroidal neovascularization in pediatric patients with symptomatic choroidal
Growth rate, impact of smoking and management of incidentally found paranasal sinus osteomas. To build upon existing literature regarding growth rate of asymptomatic, incidentally found paranasal sinus (PNS) osteomas, evaluate potential factors associated with growth rate and present an argument for how to follow up. At our institution, EPIC SlicerDicer was used to screen imaging studies using keyword 'osteoma' and included patients with at least 2 imaging studies 6 months apart that both demonstrated a PNS osteoma(s). Imaging studies with the largest time interval were selected. Non-PNS osteomas were excluded. 47 patients that fit this criterion with a median duration of interval imaging of 35.9 months. Growth rate was measured to be 0.39 mm/year in the cephalocaudal direction and 0.45 mm

The patient denied nighttime pain, fever, or chills. Laboratory investigation revealed the following normal values: hemoglobin level of 15.6 g/dL (normal range, 13-16 g/dL), platelet count of 240 × 103/µL (normal
To biopsy or not to biopsy: a retrospective review of presumed osteoid osteomas treated by radiofrequency ablation. First, to determine the frequency and spectrum of osteoid osteoma (OO)-mimicking lesions among presumed OO referred for radiofrequency ablation (RFA). Second, to compare patient sex and age, lesion location, and rates of primary treatment failure for OO based on histopathology
Clinical Features and Treatment Outcomes of Choroidal Osteoma in Asian Indians (80 Patients). To describe the demographic and clinical characteristics, and treatment outcomes of choroidal osteoma in Indian patients. This cross-sectional hospital-based study included 80 patients (100 eyes) between 2nd October 2012 and 15th May 2024. Forty-nine (61%) participants were female, and 31 (39 %) were , transpupillary thermotherapy in 3, and focal laser photocoagulation in one eye to the perifoveal leaning edge with SRF without CNV. The mean BCVA changed from 0.4 to 0.6 logMAR units (6/15 to 6/24 Snellen's equivalent) at a mean follow-up of 19 months (3-149 months). Choroidal osteoma is a unilateral condition observed in females. Although benign, the presence of CNV, SRF, or tumor growth requires treatment
Management and clinical-outcome of juxta-articular osteoid osteoma lesions. Osteoid osteoma (OO) is a benign intra-osseous lesion. The lesion is painful and usually diagnosed by x-ray, computed tomography (CT) or magnetic resonance imaging (MRI). When the lesion is juxta-articular or intra-capsular, the symptoms may present differently than the typical OO lesion and make diagnosis more challenging. Proximity to articular cartilage may make the treatment with radiofrequency ablation more dangerous. This study presents an 11-year experience in managing juxta-articular osteoid osteoma (JAOO) including long-term follow-up, while using CT-guided radiofrequency ablation (CT-RFA). All patients diagnosed with OO and managed with CT-RFA between 2010 and 2020 were reviewed. Those with a lesion
Single-port Endoscopic Removal of Forehead Osteoma: An Otolaryngologist's Procedure. For otolaryngologists, single-port endoscopic removal of forehead osteoma draws upon a familiar skill set and is a robust technique for complete tumor removal with excellent cosmesis. Laryngoscope, 2023.
The malignant transformation of osteoid osteoma in the cervical spine to high-grade osteosarcoma: a case report and review of literature. Osteoid osteoma occasionally occur in the spine, but their malignant transformation is not common. We present an extremely rare case of the malignant transformation of an osteoid osteoma to high-grade osteosarcoma that formed in the pedicle and spread months after the initial diagnosis. At this stage, the tumour size was approximately 6-fold larger than the initial size, and resulted in progressive paraplegia. A biopsy revealed that the tumour had transformed into a high-grade osteosarcoma. Heavy charged particle irradiation was performed to control tumour growth. There is a possibility of malignant transformation of osteoid osteoma. Patients
Osteoid osteomas of the hip: a well-recognized entity with a proclivity for misdiagnosis. The diagnosis of osteoid osteomas (OO) about the hip can be challenging as presenting symptoms can mimic other, more common, periarticular pathologies. Our aims were to identify the most common misdiagnoses and treatments, mean delay in diagnosis, characteristic imaging features and provide tips . Consideration of OO in the differential diagnosis of hip pain in adolescent patients and awareness of the characteristic imaging findings are critical for making an accurate diagnosis. • The diagnosis of osteoid osteoma of the hip can be challenging, as demonstrated by long delays in time to initial diagnosis and high rates of misdiagnoses which can lead to inappropriate interventions. • Familiarity
Comparison of arthroscopy versus percutaneous radiofrequency thermal ablation for the management of intra- and juxta-articular elbow osteoid osteoma: case series and a literature review. Today, intra-articular and juxta-articular osteoid osteomas are treated with arthroscopy and radiofrequency thermal ablation. However, for the case of an elbow joint, arguments are made for the use of a minimally invasive technique to be the optimal choice. This study aims to analyse our experiences of arthroscopically treated elbow osteoid osteomas and to compare it with the published results of both techniques. The retrospective study analyses the patients who underwent elbow arthroscopy ablation of an elbow osteoid osteoma at a single institution from January 2014 until March 2020. Clinical
Ossicular chain reconstruction using costal cartilage in malleoincudal osteoma. To report an extremely rare case of malleoincudal osteoma that led to conductive hearing loss despite an unusually normal otomicroscopic appearance, and to highlight the usefulness of costal cartilage for ossicular chain reconstruction after tumour removal. A 37-year-old woman presented with a 2-year history malleoincudal osteoma were removed. Ossicular chain reconstruction using costal cartilage was performed at the time of tumour removal. The possibility of a middle-ear osteoma must be considered in cases of unilateral and progressive conductive hearing loss with a normal otomicroscopic appearance in patients with no history of ear infection, trauma or prior surgery, and with no family history of hearing loss
Osteoid Osteoma: Percutaneous CT-guided Cryoablation Is a Safe, Effective, and Durable Treatment Option in Adults.

Purpose To evaluate percutaneous CT-guided cryoablation for the treatment of osteoid osteoma in young patients and adults. Materials and Methods This retrospective study reviewed data from 50 consecutive patients who underwent percutaneous CT-guided cryoablation for the treatment of osteoid osteoma between January 2013 and June 2019 in a single institution. In 30 of 50 patients (60%), the procedure
Predicting Visual Outcomes in Choroidal Osteoma Treated with Anti-vascular Endothelial Growth Factor. To determine potential factors associated with the long-term visual prognoses in patients with choroidal osteoma undergoing anti-vascular endothelial growth factor (VEGF) treatment. Retrospective case series. Patients diagnosed at tertiary high-volume hospitals between January 2000 and December 2020 were evaluated. The primary outcome measure was visual acuity at 5-year follow-up. The secondary outcome measures included factors associated with favorable vision, defined as loss of <1 line and >20/200 vision. Of 38 eyes from 36 patients (22 female, 61%; mean age 38 years) with choroidal osteoma, 23 eyes (61%) received anti-VEGF treatment (bevacizumab 1.25mg/0.05 cc, monthly or treat
Experience with three-dimensional exoscope-assisted surgery of giant mastoid process osteoma. The excision of a giant mastoid process osteoma can be challenging. In such situations, the three-dimensional exoscope intra-operative optic may be a promising tool. This paper provides a technical description of a giant mastoid osteoma excised under three-dimensional exoscope magnification . A fragmented excision by intralesional curettage was adopted to prevent peri-tumoural damage. This technique had been previously described for the excision of large osteomas of the sinus. The three-dimensional exoscope magnification tool had excellent applicability during surgery of a rare mastoid osteoma. In complex anatomical areas, the cavitation and fragmented excision of the tumour may prevent
Optical coherence tomography angiography findings of choroidal neovascularization secondary to decalcified choroidal osteoma treated with intravitreal aflibercept: A case report. Choroidal osteoma (CO) is a rare benign ocular tumor characterized by ossifying choroid lesions. To the best of our knowledge, this is the first detailed report to describe the optical coherence tomography angiography
Maxillary sinus osteoma: A case report and literature review. This case report describes a rare presentation of an osteoma in the maxillary sinus picked up from an incidental finding on an orthopantomogram that was obtained to inform orthodontic treatment. While orthodontists principally use this radiograph to assess the developing dentition, aid treatment planning and monitor treatment, several peripheral anatomical sites are evident on this radiograph. We review the literature in relation to osteomas presenting in the craniofacial area along with its management. We provide examples of common radiopaque lesions along with their radiographic features that dental healthcare clinicians may encounter.
Polypoidal choroidal vasculopathy as a complication of choroidal osteoma: A case report. Choroidal osteoma (CO) is a rare benign tumor that particularly affects young, healthy women. Its prognosis is influenced by complications, such as choroidal neovascularization (CNV), subretinal hemorrhage, subretinal fluid (SF), decalcification status, and overlying retinal pigment epithelium (RPE) atrophy
