Relapsing polychondritis (RP) is a rare autoimmune disorder of unknown etiology characterized by recurrent episodes of inflammation and the destruction of cartilaginous tissues, primarily involving the ear, nose, and the respiratory tract. Nasal chondritis is present in 24% of patients at the time of diagnosis and develops subsequently in 53% throughout the diseases progress. Progressive destruction of nasal cartilage leads to the characteristic flattening of the nasal bridge, resulting in the saddle nose deformity. In patients with RP, surgical management for saddle nose is carefully decided due to the disease relapsing characteristics. We present a RP patient with a saddle nose deformity who underwent reconstruction rhinoplasty with autologous costal cartilage grafting. At 6-month follow-up, the patient retained good esthetic results and showed neither complication nor relapse of RP.

Objective: Simultaneous anterior cerebral artery (ACA) and middle cerebral artery (MCA) occlusion is rare. We investigated the clinical and radiological outcomes of patients with simultaneous ACA and MCA occlusion treated with mechanical thrombectomy. Methods: We analyzed the clinical and radiological outcomes of 12 patients with simultaneous ACA and MCA occlusion treated with mechanical thrombectomy from January 2018 to December 2020. The clinical outcome was assessed using the modified Rankin Score (mRS) after 3 months of thrombectomy. The radiological outcome was assessed using the thrombolysis in cerebral infarction (TICI) score. Results: The median National Institutes of Health Stroke Scale score at hospital arrival was 18 (interquartile range, 16–20). M1 was the most common occlusion lesion (n=8), and A3 was the most common lesion in the ACA (n=6). Six patients were first treated for MCA occlusion and later for ACA occlusion (MCA group). Other patients were first treated for ACA occlusion and later for MCA occlusion (ACA group). There was no difference in clinical outcomes between the MCA and ACA groups (p=0.180). Successful recanalization (TICI ≥2b) of MCA was achieved in 10 patients (83.3%). Successful recanalization of ACA was achieved in 10 patients (83.3%). Successful recanalization of both ACA and MCA occlusion was observed in eight patients (66.7%). Three patients (25%) had good clinical outcomes (mRS ≤2). Conclusions In our series, simultaneous ACA and MCA occlusion showed relatively poor successful recanalization rates and poor clinical outcomes despite treatment with mechanical thrombectomy.

Procedure-related subarachnoid hemorrhage (SAH) after mechanical thrombectomy is known to be a clinically benign presentation. However, the treatment in the presence of definite contrast leakage without vessel rupture is controversial. Here, we report a case in which a salvage technique was performed for procedure-related SAH after mechanical thrombectomy for a proximal M3 occlusion.
A 56-year-old female patient presented with global aphasia and right hemiparesis within 2 hours after symptom onset. The initial National Institute of Health Stroke Scale score of the patient was 18 points, and Computed tomography (CT) angiography showed that the superior division of the left middle cerebral artery (MCA) was occluded. We decided to treat the patient with mechanical thrombectomy. Control angiography showed a left proximal M3 occlusion. We performed mechanical thrombectomy with a partially deployed technique using a Trevo 3 mm stent (Stryker). Control angiography showed recanalization of the occluded vessel but contrast leakage after stent retrieval. We decided to treat the lesion presenting with contrast leakage with stenting using a Neuroform Atlas 3 mm stent (Stryker). Serial control angiography continued to show contrast leakage of the recanalized artery. We decided to treat the lesion with temporary balloon occlusion using a Scepter C balloon catheter (MicroVention). The patient recovered and had a modified Rankin scale score at discharge of 0.
Given the results of our case, stenting and subsequent repeat temporary balloon occlusion should be considered for SAH with contrast leakage after mechanical thrombectomy, as spontaneous cessation of the arterial bleeding is unlikely.

BACKGROUND: Keloids are benign fibro-proliferative lesion, related to excessive inflammatory reactions in certain anatomical areas, including the auricles. Their specific etiology remains unclear; nonetheless they exhibit tumor-like characteristics of significant recurrence and cause emotional distress, even with various treatment strategies. We applied intermittent magnetic pressure therapy on ear keloids in combination with surgical excision, and present its effectiveness herein.METHODS: Ear keloid patients were treated with surgical excision followed by magnetic pressure therapy. The keloid tissues underwent excision and keloid marginal flaps were utilized for wound closure. Intermittent magnetic pressure therapy was applied 2 weeks after the surgical procedure. The pressure therapy consisted of a 3-hour application and 2-hour resting protocol (9 hr/day), and lasted for 6 months. The results were analyzed 6 months after the therapeutic procedures, using the scar assessment scale.RESULTS: Twenty-two ear keloids from 20 patients were finally reviewed. Among the keloids that completed the therapeutic course, 20 ear keloids out of 22 in total (90.9%) were successfully eradicated. Two patients (2 keloids) exhibited slight under-correction. Postoperative complications such as wound dehiscence or surgical site infection were not noted. The scar assessment scale demonstrated a significant improvement in each index. The intermittent pressure therapy led to patient compliance, and avoided pressure-related pain and discomfort.CONCLUSION: Excision followed by intermittent pressure application using a magnet successfully reduced the burden of fibro-proliferative keloids, and had good patient compliance. The role of intermittent pressure application and resting should be studied with regard to keloid tissue remodeling.

The scalp is the thickest skin in the body and protects the intracranial structures. The coverage of a large scalp defect is a difficult surgical procedure, the full details of which must be considered prior to the procedure, such as defect size and depth, and various factors related to the patient’s general condition. Although a free flap is the recommended surgical procedure to cover large scalp defects, it is a high-risk operation that is not appropriate for all patients. As such, other surgical options must be explored. We present the case of a patient with an ulcer on the scalp after wide excision and split-thickness skin graft for squamous cell cancer. We successfully performed a reverse temporalis muscle flap for this patient.

A checkrein deformity can occur after a distal tibiofibular fracture. Usually, a checkrein deformity due to a dysfunction of the extensor hallucis longus muscle is rarer than that of the flexor hallucis longus. Only a few related studies have been reported. The authors encountered an extensor hallucis longus checkrein deformity due to extensor retinaculum syndrome while managing a triplane fracture. In magnetic resonance imaging, an increase in the heterogeneous signal was observed on the T2-weighted images suggesting muscle necrosis or ischemic changes in a part of the extensor hallucis muscle. Postoperative great toe motor weakness, unintentional movement, sensory changes, and weakness improved spontaneously during the follow-up.

Juvenile psammomatoid ossifying fibroma (JPOF) is a rare, benign, fibro-osseous variant of ossifying fibroma. It exhibits short-term rapid growth and has a high recurrence rate. Herein we describe a case of JPOF of the maxilla that was treated via complete excision utilizing an intraoral approach with immediate reconstruction using an iliac bone graft, in conjunction with a comprehensive review of the literature. A 20-year-old man presented with a mass on his right cheek that he reported had been growing over the last 10 months. In that cheek he had noticed fullness and experienced pressure, tenderness, and fluffiness, with no other ophthalmic or dental symptoms. After clinical, radiological, and histological examinations, the diagnosis was confirmed as JPOF. Surgical excision was performed, followed by immediate reconstruction with an autologous iliac cortical and cancellous bone graft harvested from the right iliac crest under general anesthesia. Good cicatrization of the intraoral surgical wounds and right iliac crest were evident. He was monitored for 6 months after the surgery and exhibited appropriate midfacial contour. There were no signs of recurrence or complications.

BACKGROUND: This study was conducted to determine the relationship between third molar (M3) and mandibular fracture.METHODS: Patients with unilateral mandibular angle or condyle fractures between 2008 and 2018 were evaluated retrospectively. Medical records were reviewed regarding the location of fractures, and panoramic radiographs were reviewed to discern the presence and position of ipsilateral mandibular third molars (M3). We measured the bony area of the mandibular angle (area A) and the bony area occupied by the M3 (area B) to calculate the true mandibular angle bony area ratio (area A–B/area A× 100).RESULTS: The study consisted of 129 patients, of which 60 (46.5%) had angle fractures and 69 (53.5%) had condyle fractures. The risk of angle fracture was higher in the presence of M3 (odds ratio [OR], 2.2; p< 0.05) and the risk of condyle fracture was lower in the presence of M3 (OR, 0.45; p< 0.05), than in the absence of M3. The risk of angle fracture was higher in the presence of an impacted M3 (OR, 0.3; p< 0.001) and the risk of condyle fracture was lower in the presence of an impacted M3 (OR, 3.32; p< 0.001), than in the presence of a fully erupted M3. True mandibular angle bony area ratio was significantly lower in the angle fractures than in the condyle fractures (p= 0.003).CONCLUSION: Angle fractures had significantly lower true mandibular angle bony area ratios than condyle fractures. True mandibular angle bony area ratio, a simple and inexpensive method, could be an option to predict the mandibular fracture patterns.

BACKGROUND: This study was conducted to determine the effect of the distributional relationship between dental roots and the mandibular bone on single mandibular bone fractures, which are common craniofacial fractures. METHODS: This was a retrospective, single-center study in Seoul, Korea. Patients with single mandibular fractures in the symphysis, parasymphysis, body, and angle area, with tooth structure involvement were included. The control group included patients with simple, bone-level lacerations without fractures. In total, 94 patients (72 males and 22 females) were included in the treatment group, and 125 (71 males and 54 females) were included in the control group. The height of the mandibular bone and the dental root were measured with panoramic radiography. The central incisor represented the symphysis area, the canine represented the parasymphysis area, the first molar represented the body area, and the second molar represented the angle area. RESULTS: In the treatment group, symphysis fractures occurred in 16 patients (17%), parasymphysis fractures in 36 patients (38%), body fractures in 17 patients (18%), and angle fractures in 25 patients (27%). The ratios of the dental roots to the total height of the mandibular bone in the treatment group were 30.35%, 39.75%, 39.53%, and 36.27% for symphysis, parasymphysis, body, and angle areas, respectively, whereas in the control group, they were 27.73%, 39.70%, 36.76%, and 35.48%. The ratios of the treatment group were significantly higher than those of the control group. CONCLUSION: The results show that the higher ratio of the dental root to the height of the mandibular bone increases the fracture risk.
