Treatment of Osteoid Osteomas Using a Navigational Bipolar Radiofrequency Ablation System
CardioVascular and Interventional Radiology, 2016Co-Authors: Adam N. Wallace, Anderanik Tomasian, Randy O. Chang, Jack W. JenningsAbstract:Background Percutaneous CT-guided radiofrequency ablation is a safe and effective minimally invasive treatment for osteoid Osteomas. This technical case series describes the use of a recently introduced ablation system with a probe that can be curved in multiple directions, embedded thermocouples for real-time monitoring of the ablation volume, and a bipolar design that obviates the need for a grounding pad. Methods Medical records of all patients who underwent radiofrequency ablation of an osteoid Osteoma with the STAR Tumor Ablation System (DFINE; San Jose, CA) were reviewed. The location of each osteoid Osteoma, nidus volume, and procedural details were recorded. Treatment efficacy and long-term complications were assessed at clinical follow-up. Results During the study period, 18 osteoid Osteomas were radiofrequency ablated with the multidirectional bipolar system. Lesion locations included the femur (50 %; 9/18), tibia (22 %; 4/18), cervical spine (11 %; 2/18), calcaneus (5.5 %; 1/18), iliac bone (5.5 %; 1/18), and fibula (5.5 %; 1/18). The median nidus volume of these cases was 0.33 mL (range 0.12–2.0 mL). All tumors were accessed via a single osseous channel. Median cumulative ablation time was 5 min and 0 s (range 1 min and 32 s–8 min and 50 s). All patients with clinical follow-up reported complete symptom resolution. No complications occurred. Conclusion Safe and effective CT-guided radiofrequency ablation of osteoid Osteomas can be performed in a variety of locations using a multidirectional bipolar system.

an unusual case of chronic lateral foot pain following ankle inversion injury osteoid Osteoma of the tarsal cuboid bone
Foot and Ankle Specialist, 2014Co-Authors: Umur Aydogan, Samuel G DellenbaughAbstract:Osteoid Osteomas are common benign tumors normally seen in the femur, tibia, and spine. They rarely are seen in the foot. We present an unusual case of osteoid Osteoma of the cuboid in a 26-year-old man. This was initially thought to be an ankle sprain, as its first presentation was after a sporting injury. It was then treated as an infection before the true diagnosis—that of osteoid Osteoma—was obtained.Level of Evidence: Therapeutic, Level IV: Case study

giant ethmoid Osteoma with orbital extension a nasoendoscopic approach using an intranasal drill
Laryngoscope, 2001Co-Authors: Hungmeng Huang, Chiaming Liu, Kainan Lin, Hanntsong ChenAbstract:Objective Ethmoid Osteoma is a slow-growing, benign, and encapsulated bony tumor. Symptoms occur earlier than with Osteomas of the frontal sinus because of the small volume of the ethmoid sinus. Interestingly, orbital extension is uncommon. Treatment remains controversial, with open procedures typically being used. In this article, we present a less invasive yet safe and effective approach to treatment. Study Design A nasoendoscopic approach using a Stammberger-Saches intranasal drill was developed for treatment of patients with ethmoid Osteoma, with or without orbital extension. Between 1995 to 1999, seven patients underwent the new surgical procedure. Methods All procedures were performed under general anesthesia. Using 0° and 30° endoscopes, surface anesthesia of the nasal mucosa was performed, the anterior ethmoid cell was resected, and the whitish Osteoma found. The Osteoma was drilled out inferolaterally to superomedially. In the patient with orbital extension, a double-ended blunt elevator was used to separate the remaining Osteoma from the lamina papyracea and to push the residual Osteoma medially toward the nasal septum. With alternate drilling and elevation, the Osteoma was gently removed. The surgical site was then packed. Results The method successfully treated all patients. There were no major complications. The single patient with orbital extension had mild postoperative periorbital ecchymoses. Nasoendoscopy showed normal epithelialization 4 to 6 weeks after surgery. Computed tomography showed no residual tumors 6 months after surgery. Conclusion The 30° nasoendoscopic approach using an intranasal drill provides a good operative field and is a safe and effective technique, with the potential to become the treatment of choice in selected cases.

ethmoid sinus Osteoma presenting as epiphora and orbital cellulitis case report and literature review
Survey of Ophthalmology, 1999Co-Authors: Ahmad M Mansour, Haytham I Salti, Sami H Uwaydat, Rola Dakroub, Ziad BashshourAbstract:Paranasal sinus Osteoma is a slow-growing, benign, encapsulated bony tumor that may be commonly asymptomatic, being detected incidentally in 1% of plain sinus radiographs or in 3% of sinus computerized tomographic scans. In a patient presenting with orbital cellulitis and epiphora, computed tomography disclosed a large Osteoma of the ethmoid sinus. Excision of the Osteoma allowed recovery of vision, return of extraocular muscle function, and resolution of choroidal folds. Proptosis, diplopia, and visual loss are other frequent presenting signs of paranasal Osteomas. Epidemiology, diagnosis, treatment, and pathologic findings in paranasal sinus Osteoma are reviewed.

osteoid Osteoma percutaneous laser ablation and follow up in 114 patients
Radiology, 2007Co-Authors: Afshin Gangi, Houman Alizadeh, Lisa Wong, Xavier Buy, Jeanlouis Dietemann, C RoyAbstract:Purpose: To retrospectively evaluate the effectiveness of interstitial laser ablation (ILA) as a curative treatment of osteoid Osteoma. Materials and Methods: Ethical review board approval was obtained for the retrospective study. Informed consent was waived. From June 1994 to June 2004, 114 patients (mean age, 22.3 years) suspected of having osteoid Osteoma underwent ILA with a diode laser (805 nm). An optical fiber was introduced into the nidus of the osteoid Osteoma, and 400–3000 J of energy was delivered, depending on the size and location of the nidus. Twelve spinal osteoid Osteomas were treated; in five of these cases, the nidus was located fewer than 8 mm from the adjacent nerve roots, and slow epidural or periradicular infusion of normal saline was used to avoid thermal damage to neurologic structures. Pain was evaluated with a visual analog scale (VAS) and medication. ILA was considered successful (score, 0) when complete pain relief was achieved (VAS score, <1) without medication.
