INTRODUCTION
Osteoblastoma is an uncommon benign bone tumor characterized by the formation of osteoid tissue, occurring more frequently in men than in women. It is often associated with osteoid osteoma and can be found at various locations in the skeleton, although it is rare in the sacrum. Typically, these lesions involve the posterior elements of the spine, including the pedicle and the lamina. We would like to present a case of sacral osteoblastoma, clinically presenting as lumbar radiculopathy, which was treated at our institute.
CASE REPORT
A 23-year-old male presented to us with left gluteal pain radiating to the left lower limb pain for 2 years. He had multiple consultations elsewhere and was being treated as a probable case of a lumbar disc lesion with left lower limb radiculopathy. X-rays appeared normal. Magnetic resonance imaging of the lumbar spine and pelvis revealed a T2 hyperintense lesion affecting the posterior elements of S3, compressing the nerve roots. Computed tomography (CT) was a better investigation modality for osteoblastoma. En bloc excision and curettage were performed, and the histopathological analysis confirmed the diagnosis of osteoblastoma. The patient had immediate relief of symptoms postoperatively with no complications. At 2-year follow-up, the patient had no evidence of recurrence on a follow-up CT scan.
CONCLUSION
Osteoblastomas predominantly occur in the spine, with rare instances in the sacrum. Treatment typically involves en bloc excision. Confusing clinical presentation may delay diagnosis, resulting in persistent morbidity.

Review
To analyze the etiology, diagnosis, and treatment of unexplained conductive hearing loss (UCHL) with intact tympanic membrane. A systematic review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A total of 642 articles were retrieved from databases such as PubMed, Embase, Web of Science, and Cochrane. Fifty-four research articles and 21 case reports were screened out according to the inclusion and exclusion criteria for analysis of the etiology of UCHL. Seven research articles with UCHL who underwent exploratory tympanotomy were selected for data extraction and analysis of clinical characteristics. UCHL is a common manifestation of various diseases, including congenital ossicular anomalies (COA), otosclerosis (OTS), congenital middle ear cholesteatoma (CMEC), oval window atresia, superior semicircular-canal dehiscence, congenital stapedial footplate fixation, middle ear osteoma or adenoma, congenital ossification of stapedial tendon, and so on. A total of 522 patients were included in the 7 articles; among whom OTS showed a tendency to increase with age. The main symptoms were hearing loss, followed by tinnitus, dizziness, ear fullness, ear pain, facial paralysis. A total of 87.5% to 93.0% patients with COA manifested as nonprogressive deafness that occurred since childhood, with tinnitus incidence of 15.6% to 30.2%, and 86.4% to 96.4% patients with OTS presented with progressive hearing loss, with tinnitus incidence of 60.1% to 90.9%. The diagnosis positive rate of high-resolution computed tomography (HRCT) was 33.8% to 87.1%, and CMEC was higher than that of COA (83.3%-100% vs 28.6%-64%). All the articles reported good hearing recovery. The most common surgical complications included taste abnormalities, tinnitus, and dizziness. UCHL presents with similar clinical manifestations and poses challenges in preoperative diagnosis. Exploratory tympanotomy is the primary method for diagnosis and treatment, with good prognosis after removing the lesion and reconstructing hearing during the operation. Children can also safely undergo the surgery.

Lingual osteoma, a rare, benign bone tumor that primarily affects the posterior tongue, can be difficult to diagnose. This study aims to report a case of osteoma affecting the tongue in a 17-year-old female. The patient had a foreign body sensation and a progressively growing lesion for 3 years and underwent clinical examination and diagnostic procedures. A well-defined, smooth-surfaced, white mass was discovered in the posterior third of the tongue. The 1.5 × 1 × 0.4 cm mass was completely excised under local anesthesia and histopathologically confirmed as a benign lingual osteoma. The 2-month post-operative outcome was uneventful. The rarity of lingual osteoma, as well as the fact that it is often asymptomatic, makes diagnosis difficult. The diagnosis entails a proper clinical examination, imaging studies, and histopathological analysis. Surgical intervention, primarily aimed at complete excision while preserving tongue function, remains the primary treatment option. Successful excision entails educating healthcare professionals about this rare benign bony tumor to ensure the best possible patient outcomes.

A choroidal osteoma (CO) is a relatively rare, benign tumor with ossification that develops in the choroid and undergoes enlargement and decalcification in its natural course. Photodynamic therapy (PDT) is used to induce decalcification, but there are few reports on individual cases treated with PDT. A 47-year-old Japanese man who had reduced decimal visual acuity (VA) of the right eye to 0.7 due to a CO away from the fovea was treated with PDT. The PDT resulted in a partial decalcification of CO, and the visual acuity improved to 1.0. However, the tumor slowly expanded, eventually reaching the central fovea. Decalcification and focal choroidal excavation occurred during this natural course of the disease. Although his metamorphopsia worsened, his VA was maintained at 1.0. This case highlights that a CO partially decalcified after PDT can still enlarge and decalcify over several years. These findings indicate the need for careful and continuous monitoring of eyes with a CO.

Gardner syndrome is a rare genetic cancer predisposition disorder characterized by intestinal polyposis, multiple osteomas, and soft and hard tissue tumors. Dental anomalies are present in approximately 30%-70% of patients with Gardner syndrome and can be discovered during routine dental examinations. However, sometimes the diagnosis is challenging due to the high clinical variability and incomplete clinical picture. Herein, we report a family with various dental and bone anomalies, in which the definitive diagnosis was established with the help of a comprehensive genetic analysis based on state-of-the-art next-generation sequencing technology. A 17-year-old female index patient presented with dental (caries, impacted, retained and anteriorly located teeth) and atypical bone anomalies not resembling Gardner syndrome. She was first referred to our Genetic Counselling Unit at the age of 11 due to an atypical bone abnormality identified by a panoramic X-ray. Tooth 3.6 was surgically removed and the histopathology report revealed a Paget's disease-like bone metabolic disorder with mixed osteoblastic and osteoclastic activity of the mandible. A small lumbar subcutaneous tumor was discovered by physical examination. Ultrasound examination of the tumor raised the possibility of a soft tissue propagation of chondromatosis. Her sister, 2 years younger at the age of 14, had some benign tumors (multiple exostoses, odontomas, epidermoid cysts) and impacted teeth. Their mother had also skeletal symptoms. Her lower teeth did not develop, the 9th-10th ribs were fused, and she complained of intermittent jaw pain. A cranial CT scan showed fibrous dysplasia on the cranial bones. Whole exome sequencing identified a heterozygous pathogenic nonsense mutation (c.4700C>G; p.Ser1567*) in the gene in the index patient's DNA. Targeted sequencing revealed the same variant in the DNA of the other affected family members (the sister and the mother). Early diagnosis of this rare, genetically determined syndrome is very important, because of the potentially high malignant transformation of intestinal polyps. Dentists should be familiar with the typical maxillofacial features of this disorder, to be able to refer patients to genetic counseling. Dental anomalies often precede the intestinal polyposis and facilitate the early diagnosis, thereby increasing the patients' chances of survival. Genetic analysis may be necessary in patients with atypical phenotypic signs.

INTRODUCTION AND IMPORTANCE
Osteoid osteoma is a benign primary bone tumor with a predilection for the long bones and vertebrae, presenting a unique challenge when occurring in rare locations such as the talus, accounting for 5 to 8 % of cases. Early imaging struggles to detect its nidus, leading to diagnostic delays, especially when atypical symptoms and previous trauma complicate clinical presentations. This case report illustrates the diagnostic challenges and emphasizes the importance of targeted computed tomography (CT) guided by scintigraphy in diagnosing osteoid osteoma of the talus.
CASE PRESENTATION
A 23-year-old male presented with chronic left ankle pain spanning three years, with a history of previous trauma. Initial evaluations including standard radiology and magnetic resonance imaging (MRI) suggested algodystrophy of the talus and tenosynovitis, but failed to identify the osteoma. Persistent pain led to further investigation with bone scintigraphy, revealing hyperfixation indicative of partial algodystrophy. Targeted CT scans focused on the scintigraphy-identified area ultimately revealed an osteoid osteoma's nidus, enabling successful surgical intervention and symptomatic relief.
DISCUSSION
The diagnosis of osteoid osteoma in the talus is frequently delayed due to its atypical presentation and rare occurrence. Traditional imaging techniques may overlook the tumor's nidus, underscoring the necessity for targeted diagnostic approaches. This case demonstrates the value of integrating scintigraphy with targeted CT to enhance early diagnosis and treatment planning, contrasting with the limited diagnostic yield of MRI and underscoring CT's superiority for nidus detection.
CONCLUSION
Osteoid osteoma of the talus poses significant diagnostic challenges. This case report highlights the utility of scintigraphy-guided targeted CT in identifying the nidus and facilitating prompt surgical management, advocating for a multidisciplinary approach to atypical ankle pain, especially in patients with a history of trauma.

Soft tissue calcifications frequently appear on imaging studies, representing a prevalent but non-specific discovery, varying from a local reaction without clear cause to suggesting an underlying systemic condition. Because calcifications like these can arise from various causes, an accurate differential diagnosis is crucial. Differential diagnosis entails a methodical assessment of the patient, encompassing clinical presentation, medical history, radiological and pathological findings, and other pertinent factors. Through scrutiny of the patient's medical and trauma history, we can refine potential causes of calcification to vascular, metabolic, autoimmune, neoplastic, or traumatic origins. Furthermore, routine laboratory assessments, including serum levels of calcium, phosphorus, ionized calcium, vitamin D metabolites, and parathyroid hormone (PTH), aid in identifying metabolic etiologies. We describe a rare occurrence of osteoma cutis in a 15-year-old female patient with a history of pseudohypoparathyroidism (PHP) and Albright's hereditary osteodystrophy (AHO). The patient presented with a painful mass on the lateral side of her left foot. The diagnosis was based on medical history, laboratory tests, and imaging, leading to an excisional biopsy and complete pain relief post-surgery. Understanding such rare occurrences and related conditions is crucial for accurate diagnosis and management.

The aim of this study was to evaluate treatment of osteoid osteomas using bipolar radiofrequency ablation (RFA) and patients' quality of life before and after therapy. We retrospectively evaluated patients who underwent bipolar RFA of osteoid osteomas between 2001 and 2016. We assessed patients' symptoms before and after treatment (four weeks after treatment and long-term) using a questionnaire including severity and quality of pain on a 10-point scale (1 = no pain, 10 = severe pain), motion restrictions, pain-related sleep disorders, and necessary pain medication. In addition, we evaluated technical success, complications, hospitalization length, and patients' satisfaction with treatment. This study included 62 patients (43 [69.4%] males, 26.2 ± 13.2 years). Average nidus size was 5.7 ± 2.6 mm. The rate of technical success was 100%. All RFAs were performed without any complications. One patient showed a recurrence, resulting in a recurrence rate of 1.6%, which was successfully treated by another session of RFA. Average hospitalization length was 1.5 ± 0.5 days. A total of 36 patients (58.1%) participated in the questionnaire, reporting an average pain severity of 8.2 ± 1.6 before RFA compared to 3.4 ± 3.0 four weeks after and an average of 2.1 ± 2.3, 6.6 years after therapy, (both < 0.001). After therapy, 31 (86.1%) patients had no pain. The majority of patients ( = 34, 94.4%) had reduced or absent motion restriction after therapy ( < 0.001). Patient satisfaction rate was 91.7%. In conclusion, bipolar RFA is a safe and effective treatment modality for osteoid osteomas and improves quality of life by reducing pain severity and motion restrictions.

The frontal sinus medial drainage -Draf Type III (modified endoscopic Lothrop) procedure, has become a cornerstone in frontal sinus surgery over the last three decades. Despite its widespread acceptance, challenges such as restenosis and neo-ostium closure persist, prompting the exploration of various preventive techniques. In this retrospective study, we analyzed data from 111 patients who underwent the Draf III procedure between November 2015 and November 2023, with a mean follow-up period of 3 years and 11 months. Approximately two-thirds of patients (64%) had undergone previous sinus surgery and 16% a previous Draf III. Over half of the patients had inflammatory conditions, with the majority being chronic rhinosinusitis with nasal polyps (CRSwNP) (46%), while 15% were diagnosed with malignant sinonasal tumors, and 23% with benign sinonasal tumors, of which the commonest was osteoma, accounting for 14 cases. The mean follow-up period was 3 years and 11 months. We focused on evaluating the efficacy of mucosal flaps and free grafts in preventing neo-ostium closure. Although it appears that there is no statistically significant correlation between flap usage and the need for revision surgery or ostium patency maintenance overall, subgroup analysis highlighted the benefits of flap reconstruction in patients with chronic rhinosinusitis with nasal polyps. In this subgroup, the use of flaps or grafts reduced the rate of neo-ostium stenosis from 20% to 0% ( < 0.05). Overall revision rate was 11.7%-however this was 8% in patients without acute inflammation at the time of surgery and went up to 31% in the presence of pus in the frontal recess ( = 0.02). This study contributes to the existing literature by providing insights into long-term outcomes, the enduring effectiveness of interventions in frontal sinus surgery, and especially the importance of taking into account the underlying pathology when assessing long-term outcomes.
