Osteoma is a benign osteogenic tumor, which is characterized the slow-growing proliferation of compact or cancellous bone. The etiology of the lesion is not well established. Among the hypotheses, the following are related: a traumatic factor, infectious processes, or true neoplasm due to the origin of cartilaginous cells. It can present at any age, usually in young adult individuals, with equal prevalence in both sexes. The clinical characteristics of the peripheral osteoma are represented by slow asymptomatic growth, which leads to swelling and, thus, facial asymmetry...

External auditory canal atresia (EACA) is a common otologic condition. Etiology can vary from congenital to acquired causes. It causes considerable difficulty to the patient. Bilateral ear canal atresia in children can lead to speech delays due to hearing impairment caused by this condition. Though easily diagnosed it is one of the most difficult conditions to treat. Acquired conditions can affect any age group. Restenosis following treatment is very common. This article focuses on the treatment of EACA due to different etiologies and emphasizes on special points of surgical treatment and follow up...

BACKGROUND: Augmented reality (AR) technology that can combine computer-generated images with a real scene has been reported in the medical field recently. We devised the AR system for evaluation of improvements of the body surface, which is important for plastic surgery. METHODS: We constructed an AR system that is easy to modify by combining existing devices and free software. We superimposed the 3-dimensional images of the body surface and the bone (obtained from VECTRA H1 and CT) onto the actual surgical field by Moverio BT-200 smart glasses and evaluated improvements of the body surface in 8 cases...

The foot is rarely the focus of osteoid osteoma, and only a few of those cases are related to the fifth metatarsal. The present case demonstrates that atypical symptoms with suspicious findings on plain radiographs that are not associated with trauma must be analyzed carefully to determine the nature of the lesion and perform the precise treatment to obtain and sustain the cure. A 29-year-old man presented to the outpatient clinic with a 2-year history of chronic pain in the lateral aspect of his left forefoot...

Benign bone tumours are pathologies frequently encountered in archaeological human remains, with the most common being osteoma and osteochondroma. We present the case of a juvenile individual recovered from the Necropolis of Sharuna, Middle Egypt and dated to the end of Old Kingdom and First Intermediate Period of Ancient Egypt (circa 2150 BC), showing an osteochondroma arising from the proximal epiphysis of the right tibia which, in all likelihood, affected the patellar tendon in life. Osteochondromas are usually discovered during childhood and adolescence...

A 65-year-old man with a 2-month history of left-sided neck swelling presented through the cancer pathway. There was no associated 'red flag' symptoms, and clinical examination revealed a left anterior triangle, non-pulsatile firm swelling atypical of a lymph node. Ultrasound scan imaging confirmed a complex structure with an echogenic centre and hypoechoic periphery, which was confirmed on CT as an osteoma of the hyoid.This is an extremely unusual cause of a neck lump, and an extensive literature review revealed only two previously documented cases...

An osteoid osteoma is a rare benign tumor of the carpal bones. It is extremely rarely found in the lunate bone in patients above 30 years of age. We present a case report of a 61-year-old man with an osteoid osteoma of the left wrist, which was masked by degenerative carpal bone disease and a comorbidity of an inflammatory bowel disease. The mainstay of imaging including plain radiographs, computed tomography, magnetic resonance imaging, and bone scintigraphy led to the clinical diagnosis of a lunatomalacia...

BACKGROUND AND PURPOSE: Osteoid osteoma is an infrequent but debilitating benign bone lesion which can be successfully managed by percutaneous radiofrequency ablation (RFA). There are few studies investigating the efficacy and follow-up of this treatment. An arbitrary upper limit of 15 mm has been used to differentiate between osteoid osteoma and osteoblastoma with surgery used for lesions above this limit. We aimed to analyse the cases identified from our prospectively maintained database over a ten year period since adoption of this technique in our unit...

Osteomas of the temporal bone are rare entity with incidence of 0.1% - 1% of all benign tumours of skull. They are slow growing benign lesion of temporal bone. We report a rare case of mastoid osteoma of size more than 5 cm. A 40-year-old female patient presented to us with left post auricular bony swelling of size greater than 5 cm. Diagnosis of mastoid osteoma was made after relevant investigations including High Resolution Computed Tomography (HRCT) temporal bone. Complete surgical excision was done with good cosmetic outcome without recurrence...

INTRODUCTION: Osteomas of the paranasal sinuses are benign bone tumours that produce clinical signs depending on their size and location. In most reported cases large tumours are excised by an external approach or in conjunction with an endoscopic technique. Endoscopic treatment of such tumours is a huge challenge for the operator. OBJECTIVE: Determine the optimal surgical approach by analysing giant osteomas of the frontal and ethmoidal sinuses in the literature...

A 12-year-old girl presented with a 1-week history of right hip pain. MRI revealed a lesion in the incompletely fused posterior triradiate cartilage of the right acetabulum with imaging characteristics of an osteoid osteoma. The surgeon requested guidewire placement under CT guidance for lesion drilling. The CT approach was planned to avoid the usual course of the sciatic nerve, and the lesion was successfully removed and confirmed at histology to be an osteoid osteoma. At a follow-up visit, MRI showed no recurrence but demonstrated an abnormal common peroneal nerve from the sciatic notch to the popliteal fossa with denervation oedema in the tibias anterior and peroneal musculature...
