OBJECTIVE: To compare the accuracy and effectiveness of orthopaedic robot-assisted minimally invasive surgery versus open surgery for limb osteoid osteoma. METHODS: A clinical data of 36 patients with limb osteoid osteomas admitted between June 2016 and June 2023 was retrospectively analyzed. Among them, 16 patients underwent orthopaedic robot-assisted minimally invasive surgery (robot-assisted surgery group), and 20 patients underwent tumor resection after lotcated by C-arm X-ray fluoroscopy (open surgery group). There was no significant difference between the two groups in the gender, age, lesion site, tumor nidus diameter, and preoperative pain visual analogue scale (VAS) scores ( P>0.05). The operation time, lesion resection time, intraoperative blood loss, intraoperative fluoroscopy frequency, lesion resection accuracy, and postoperative analgesic use frequency were recorded and compared between the two groups. The VAS scores for pain severity were compared preoperatively and at 3 days and 3 months postoperatively. RESULTS: Compared with the open surgery group, the robot-assisted surgery group had a longer operation time, less intraoperative blood loss, less fluoroscopy frequency, less postoperative analgesic use frequency, and higher lesion resection accuracy ( P<0.05). There was no significant difference in lesion resection time ( P>0.05). All patients were followed up after surgery, with a follow-up period of 3-24 months (median, 12 months) in the two groups. No postoperative complication such as wound infection or fracture occurred in either group during follow-up. No tumor recurrence was observed during follow-up. The VAS scores significantly improved in both groups at 3 days and 3 months after surgery when compared with preoperative value ( P<0.05). The VAS score at 3 days after surgery was significantly lower in robot-assisted surgery group than that in open surgery group ( P<0.05). However, there was no significant difference in VAS scores at 3 months between the two groups ( P>0.05). CONCLUSION Compared with open surgery, robot-assisted resection of limb osteoid osteomas has longer operation time, but the accuracy of lesion resection improve, intraoperative blood loss reduce, and early postoperative pain is lighter. It has the advantages of precision and minimally invasive surgery.

OBJECTIVE: To investigate short-term effectiveness and clinical application advantages of orthopedic robot-assisted resection for osteoid osteoma compared with traditional open surgery. METHODS: A retrospective analysis was conducted on clinical data of 48 osteoid osteoma patients who met the selection criteria between July 2022 and April 2023. Among them, 23 patients underwent orthopedic robot-assisted resection (robot-assisted surgery group), and 25 patients received traditional open surgery (traditional surgery group). There was no significant difference ( P>0.05) in gender, age, disease duration, lesion location and size, and preoperative visual analogue scale (VAS) score, and musculoskeletal tumor society (MSTS) score between the two groups. The surgical time, intraoperative blood loss, intraoperative lesion localization time, initial localization success rate, infection, and recurrence were recorded and compared. VAS scores before surgery and at 24 hours, 1, 3, 6, and 9 months after surgery and MSTS score before surgery and at 3 months after surgery were assessed. RESULTS: All patients completed the surgery successfully, with no significant difference in surgical time between the two groups ( P>0.05). Compared to the traditional surgery group, the robot-assisted surgery group had less intraoperative blood loss, shorter lesion localization time, and shorter hospitalization time, with significant differences ( P<0.05). The initial localization success rate was higher in the robot-assisted surgery group than in the traditional surgery group, but the difference between the two groups was not significant ( P>0.05). All patients in both groups were followed up, with the follow-up time of 3-12 months in the robot-assisted surgery group (median, 6 months) and 3-14 months in the traditional surgery group (median, 6 months). The postoperative MSTS scores of both groups improved significantly when compared to those before surgery ( P<0.05), but there was no significant difference in the changes in MSTS scores between the two groups ( P>0.05). The postoperative VAS scores of both groups showed a gradually decreasing trend over time ( P<0.05), but there was no significant difference between the two groups after surgery ( P>0.05). During follow-up, except for 1 case of postoperative infection in the traditional surgery group, there was no infections or recurrences in other cases. There was no significant difference in the incidence of postoperative infection between the two groups ( P>0.05). CONCLUSION Orthopedic robot-assisted osteoid osteoma resection achieves similar short-term effectiveness when compared to traditional open surgery, with shorter lesion localization time.

Objective: To explore the clinical characteristics, intervention and treatment of tympanic osteoma at different locations. Methods: The medical history, audiological and imaging examination, operation and follow-up results of two patients with tympanic osteoma at different sites were reviewed and summarized. Furthermore, the clinical characteristics and interventions of 36 patients reported in literatures with tympanic osteomas were also summarized and analyzed. Results: Osteoma of the two patients collected in this study located at promontory and incus respectively;both of them presented with intact tympanum and conductive deafness, without obvious etiology or predisposing factor. Both of them underwent surgeries and the hearing improved significantly. For patient one, the ossicular chain was intact and restored to activity after removed the osteoma. For patient two, an artificial ossicle was implanted after removed the osteoma and incus. In the 36 patients reported in literatures, the average age was 26.5 years, and 39.47% of them located at promontory; in addition, the main symptoms of them were progressive hearing loss, tinnitus and ear stuffy. Conclusions: Patients with tympanic osteoma are characterized by conduction deafness with intact tympanic membrane, and the most common lesion is promontory. Hearing can be restored by excision of the osteoma and maintenance or reconstruction of the ossicle chain.

Osteomas are benign, slow-growing osteogenic lesions frequently found in the craniomaxillofacial region. They can be classified as peripheral, central, or extraskeletal. Reactive mechanisms to trauma or infection, as well as muscle traction, are thought to play a major role in the development of peripheral osteomas. In the present report, a 41-year-old woman presented with a slow-growing, painless mass on her left eyebrow. She had suffered trauma 15 years prior. In the computed tomography scan, a 2.5 × 2 × 0.7-cm radio-opaque tumor was detected just medial to the left supraorbital foramen, and a peripheral osteoma was clinically diagnosed. An elective operation under general anesthesia was planned. Following a suprabrow incision, subcutaneous and intramuscular dissection was performed. In the surgical plane deep to the corrugator muscles and superficial to periosteum, a branch of the supratrochlear nerve was encountered and preserved using a vessel loop. The osteoma beneath the periosteum was extracted in multiple fragments using a chisel and mallet to minimize trauma to the nerve. Contour and facial symmetry were corrected. To use a suprabrow incision, the surgeon must understand neighboring anatomical structures, including the course of the supratrochlear and supraorbital neurovascular bundles. When these structures are located adjacent to tumor lesions, careful surgical maneuvers should be performed to preserve them.

STUDY DESIGN: Case report.OBJECTIVES: To report a case of osteoid osteoma arising in the sacrum in a 29-year-old male patient.SUMMARY OF LITERATURE REVIEW: Osteoid osteoma is a benign osteoblastic tumor that usually arises in the long bones. Osteoid osteoma involving the sacrum is extremely rare.MATERIALS AND METHODS: A 29-year-old male patient presented with pain localized in his sacral area for 10 months. His pain was worse at night, relieved by non-steroidal anti-inflammatory drugs, and independent of physical activity. Bone scintigraphy showed increased uptake in the second sacral vertebra (S2). Computed tomography revealed a nidus located in the S2 spinous process. Magnetic resonance imaging showed bone and soft tissue edema around the nidus.RESULTS: En bloc excision including the nidus revealed a diagnosis of osteoid osteoma and provided immediate relief of the patient's long-lasting sacral pain.CONCLUSIONS: When a young patient presents with localized sacral pain that is worse at night, relieved by non-steroidal anti-inflammatory drugs, independent of physical activity, and lasts longer than expected, proper imaging studies should be performed to rule out osteoid osteoma. Although less invasive treatment modalities have been introduced, classical en bloc excision is currently the gold standard for managing osteoid osteoma.

Osseous choristoma is a rare, benign proliferative osseous lesion, which is defined as the growth of normal tissue in an abnormal location. The etiopathogenesis for its formation is unknown, but various hypotheses have been proposed. Treatment of choice is en-bloc resection, and no recurrence has been reported. Here, we report the two cases of osseous choristoma, presented with a mass on the base of the tongue with/without globus symptom and were treated with surgical excision.

Popliteal vein aneurysms (PVAs) represent a rare form of venous aneurysms and necessitate prompt management because of their well-established risk of pulmonary embolism (PE). Herein, we report a rare case of PVA without PE, successfully treated with open surgical repair. A 27-year-old man presented to our vascular clinic with chronic pain and swelling in his left lower limb. He had a long history of facial surgeries for the removal of congenital multiple osteomas. Physical examination revealed varicosities with an abnormal distribution. Duplex ultrasound showed a left PVA measuring 2.3 cm in diameter and 4 cm in length. Open surgical excision of the PVA with lateral venorrhaphy was performed through a medial approach. Prophylactic anticoagulation was performed postoperatively. In this case, the PVA was detected, with a high degree of suspicion by the clinician, before it caused fatal PE. The patient was successfully treated with aneurysm excision and lateral venorrhaphy.

BACKGROUND AND OBJECTIVES: External auditory canal osteoma is an uncommon benign lesion and represents as unilateral solitary pedunculated mass. The aim of this study is to evaluate the clinical symptoms of osteoma and its treatment outcomes over a 10-year period in a tertiary hospital. SUBJECTS AND METHOD: Eight patients underwent operation to remove an external auditory canal osteoma at Chungbuk National University Hospital from 2008 to 2017. The medical records were retrospectively reviewed with regard to clinical characteristics, size and location of osteoma, method of surgery and treatment outcomes. RESULTS: The average age of patients was 41.8 years with the male predominance of 6:2. All of the lesions in the osteoma were unilateral and solitary (average size 5.0 mm). All of the eight cases were pedunculated: in four cases, the stalks of the osteoma were found on the tympanomastoid suture line and in three cases, it was found on the tympanosquamous suture line. Four patients were asymptomatic, where the lesions were found incidentally during unrelated evaluations. No patients were found with conductive hearing loss in the pure tone audiometry. Transcanal and endaural approach were used in five and three cases, respectively. Most of the cases were removed by curettage only, except for the two who needed additional drilling. The average surgery time was 15.6 minutes. There was no postoperative complication or recurrence. CONCLUSION: The external auditory canal osteoma was mostly unilateral and solitary. The removal of osteoma in the early stage was relatively easy with no recurrence or complication.
