Objective: To explore the feasibility and safety of the gasless transoral vestibular robotic thyroidectomy using skin suspension. Methods: The clinical data of 20 patients underwent gasless transoral vestibular robotic thyroidectomy in the Department of Otorhinolaryngology, Sun Yat-sen Memorial Hospital, Sun Yat-sen University from February 2022 to May 2022 were retrospectively analyzed. Among them, 18 were females and 2 were males, aged (38.7±8.0) years old. The intraoperative blood loss, operation time, postoperative hospital stay, postoperative drainage volume, postoperative pain visual analogue scale (VAS) score, postoperative swallowing function swallowing impairment score-6 (SIS-6), postoperative aesthetic VAS score, postoperative voice handicap index-10 (VHI-10) voice quality, postoperative pathology and complications were recorded. SPSS 25.0 was used for statistical analysis of the data. Results: The operations were successfully completed without conversion to open surgery in all patients. Pathological examination showed papillary thyroid carcinoma in 18 cases, retrosternal nodular goiter in 1 case, and cystic change in goiter in 1 case. The operative time for thyroid cancer was 161.50 (152.75, 182.50) min [M (P₂₅, P₇₅), the same below] and the average operative time for benign thyroid diseases was 166.50 minutes. The intraoperative blood loss 25.00 (21.25, 30.00) ml. In 18 cases of thyroid cancer, the mean diameter of the tumors was (7.22±2.02) mm, and lymph nodes (6.56±2.14) were dissected in the central region, with a lymph node metastasis rate of 61.11%. The postoperative pain VAS score was 3.00 (2.25, 4.00) points at 24 hours, the mean postoperative drainage volume was (118.35±24.32) ml, the postoperative hospital stay was 3.00 (3.00, 3.75) days, the postoperative SIS-6 score was (4.90±1.58) points at 3 months, and the postoperative VHI-10 score was 7.50 (2.00, 11.00) points at 3 months. Seven patients had mild mandibular numbness, 10 patients had mild cervical numbness, and 3 patients had temporary hypothyroidism three months after surgery and 1 patient had skin flap burn, but recovered one month after surgery. All patients were satisfied with the postoperative aesthetic effects, and the postoperative aesthetic VAS score was 10.00 (10.00, 10.00). Conclusion: Gasless transoral vestibular robotic thyroidectomy using skin suspension is a safe and feasible option with good postoperative aesthetic effect, which can provide a new treatment option for some selected patients with thyroid tumors.

Central nervous system involvement in primary Sjögren's syndrome (pSS) is less common and usually presents as white matter lesions, neuromyelitis optica spectrum disorder (NMOSD), or transverse myelitis. NMOSD is an immune-mediated inflammatory demyelinating disease of the central nervous system with a high rate of relapse and significant disability. Studies have shown that patients with pSS combined with NMOSD have more severe symptoms and poorer prognosis. Here, we present a case of critical illness in pregnancy-associated NMOSD combined with Sjögren's syndrome. The patient was a 30-year-old pregnant woman with a history of Sjögren's syndrome who was diagnosed with NMOSD. She received combination therapy with steroids, intravenous immunoglobulin (IVIG), and hydroxychloroquine during pregnancy, resulting in partial resolution of numbness below the waist. However, due to irregular medication adherence outside the hospital setting, she developed weakness in her right lower limb accompanied by inability to move it, while her left lower limb still had some mobility but occasional numbness along with urinary and fecal incontinence. Ten days later, she was admitted to the emergency department where an emergency cesarean section was performed to deliver a healthy baby boy. However, her condition worsened postpartum as she developed high fever accompanied by bilateral lower limb paralysis and weakness along with loss of voluntary control over urination and defecation. The patient underwent ano-ther course of treatment consisting of steroids and IVIG; however there was limited improvement in symptoms observed after this intervention. Following administration of rituximab for the first time, the patient developed urinary tract infection which was successfully managed before continuing regular infusions. In later stages the patient could walk slightly with a limp and regained control over urination and defecation, allowing her to resume normal activities. This case suggests that combination therapy with steroids, IVIG, and hydroxychloroquine should be considered for the patients with pregnancy-associated NMOSD combined with Sjögren's syndrome. Rituximab can significantly improve symptoms such as postpartum paralysis in patients with NMOSD, however, there may be a risk of infection associated with its use.

OBJECTIVES: Endoscopic prelacrimal medial maxillectomy (EPMM) was previously reported to treat maxillary inverted papilloma. This study aimed to compare prelacrimal recess approach with the conventional Caldwell-Luc approach (CLA) to remove benign maxillary sinus tumors and to evaluate the usefulness of this approach based on our experience. METHODS: Ten patients who underwent EPMM at our hospital from January 2013 to December 2017 were reviewed. We also reviewed 30 patients who underwent benign maxillary sinus tumor resection via CLA during the same period. From medical records, postoperative pathological results, complications due to surgery, and recurrence rate were evaluated. RESULTS: There were eight inverted papilloma, one ameloblastoma, and one ossifying fibroma in the EPMM group. In the CLA group, all 30 cases were inverted papilloma. There were no cases of failure at gross total removal during surgery, and no recurrences were observed during follow-up in either groups. Mean follow-up period was 13.0 months in CLA group and 10.8 months in EPMM group. Regarding postoperative complications, 11 patients of the CLA group (37%) and three patients of the EPMM group (30%) had numbness around the cheek and upper lip area after surgery (P=0.715). In the CLA group, there were eight patients who had numbness lasting more than 3 months after surgery, and two patients had numbness for more than 1 year. However, facial numbness disappeared within 3 months in all patients in the EPMM group, in which epiphora was not observed. CONCLUSION: EPMM is the effective surgical approach for resecting benign maxillary sinus tumor compared with CLA. Although facial numbness was reported in EPMM, the duration of numbness was shorter than CLA.

BACKGROUND: Ultrasound-guided interscalene brachial plexus block (US-ISB) has been reported to be effective postoperative analgesia for arthroscopic shoulder surgery. Although considered rare, various neurological complications have been reported. We retrospectively evaluated 668 patients for post operation neurological symptoms including hemidiaphragmatic paresis and post-operative neurologic symptoms after US-ISB. METHODS: We performed a retrospective chart review of 668 patients undergoing shoulder surgery with single-shot US-ISB from January 2010 to May 2015. The general anesthesia prior to the US-guided ISB procedure was standardized by expert anesthesiologists. Neurological postoperative complications were evaluated at 48 hours, about 2 weeks, 1 month, 3 months, 6 months, and up to resolution after operation. RESULTS: Three patients (0.4%) developed hemidiaphragmatic paresis (HDP), which were likely US-ISB associated and improved within 1 day. Two patients developed sensory symptoms, also likely US-ISB associated; one was paresthesia at the tip of the thumb/index finger, which resolved within 2 weeks, and the other was hypoesthesia involving the posterior auricular nerve, which resolved within 6 months. Motor and sensory symptoms which were not likely associated with US-ISB were hypoesthesia and pain (n = 28, 4.6%) and motor weakness (n = 2, 0.3%). CONCLUSIONS: Incidence of HDP and neurological complications, respectively 0.4% and 0.3%, related to transient minor sensory symptoms occurred after US-ISB for arthroscopic shoulder surgery but the complications improved spontaneously. Therefore, we confirm that the US-ISB procedure with low volumes of local anesthetics is an acceptable technique with a low rate of HDP and neurological complications.

Greater auricular nerve neuropathy is a reported as complication in some cases of shoulder arthroscopy in the beach chair position using a horse-shoe headrest. Due to this risk, intubation pad-type headrest is recommended for the beach chair position, to effectively prevent greater auricular nerve palsy. In this case report, we described a patient who experienced greater auricular nerve neuropraxia after open reduction and internal fixation with plate of clavicular fracture in beach chair position using an intubation pad-type headrest. A 49-year-old man was diagnosed with left clavicular fracture without accompanying injury or complication. He underwent an operation for open reduction and internal fixation with a plate. After surgery, the patient reported numbness, and a tingling sensation without pain or skin lesion in the auricular area and the lower margin of the left mandible. Based on the clinical symptoms, greater auricular nerve neuropraxia was diagnosed. The symptoms disappeared completely after four weeks of outpatient follow-up.

OBJECTIVE: Several surgical methods have been reported for treatment of ossification of the posterior longitudinal ligament (OPLL) in the thoracic spine. Despite rapid innovation of instruments and techniques for spinal surgery, the postoperative outcomes are not always favorable. This article reports a minimally invasive anterior decompression technique without instrumented fusion, which was modified from the conventional procedure. The authors present 2 cases of huge beak-type OPLL. Patients underwent minimally invasive anterior decompression without fusion. This method created a space on the ventral side of the OPLL without violating global thoracic spinal stability. Via this space, the OPLL and anterior lateral side of the dural sac can be seen and manipulated directly. Then, total removal of the OPLL was accomplished. No orthosis was needed. In this article, we share our key technique and concepts for treatment of huge thoracic OPLL. METHODS: Case 1. 51-year-old female was referred to our hospital with right lower limb radiating pain and paresis. Thoracic OPLL at T6–7 had been identified at our hospital, and conservative treatment had been tried without success. Case 2. This 54-year-old female with a 6-month history of progressive gait disturbance and bilateral lower extremity radiating pain (right>left) was admitted to our institute. She also had hypoesthesia in both lower legs. Her symptoms had been gradually progressing. Computed tomography scans showed massive OPLL at the T9–10 level. Magnetic resonance imaging of the thoracolumbar spine demonstrated ventral bony masses with severe anterior compression of the spinal cord at the same level. RESULTS: We used this surgical method in 2 patients with a huge beaked-type OPLL in the thoracic level. Complete removal of the OPLL via anterior decompression without instrumented fusion was accomplished. The 1st case had no intraoperative or postoperative complications, and the 2nd case had 1 intraoperative complication (dural tear) and no postoperative complications. There were no residual symptoms of the lower extremities. CONCLUSION: This surgical technique allows the surgeon to safely and effectively perform minimally invasive anterior decompression without instrumented fusion via a transthoracic approach for thoracic OPLL. It can be applied at the mid and lower level of the thoracic spine and could become a standard procedure for treatment of huge beak-type thoracic OPLL.

BACKGROUND: Midface concavity is a relatively common facial feature in East Asian populations. Paranasal augmentation is becoming an increasingly popular procedure for patients with mild concavity and normal occlusion. In this study, we evaluate clinical outcomes following a series of paranasal augmentation. METHODS: A retrospective review was performed for patients with Class I occlusion who had undergone bilateral paranasal augmentation using custom-made silicone implants, between October 2005 and September 2013. Patient charts were reviewed for demographic information, concomitant operations, and postoperative complications. Preoperative and postoperative (1-month) photographs were used to evaluate operative outcome. RESULTS: The review identified a total of 93 patients meeting study criteria. Overall, aesthetic outcomes were satisfactory. Five-millimeter thick silicone implant was used in 81 cases, and the mean augmentation was 4.26 mm for this thickness. Among the 93 patients, 2 patients required immediate implant removal due to discomfort. An additional 3 patients experienced implant migration without any extrusion. Nine patients complained of transient paresthesia, which had resolved by 2 weeks. There were no cases of hematoma or infection. All patients reported improvement in their lateral profile and were pleased at follow-up. Complications that arose postoperatively included 9 cases of numbness in the upper lip and 3 cases of implant migration. All cases yielded satisfactory results without persisting complications. Sensations were fully restored postoperatively after 1 to 2 weeks. CONCLUSION: Paranasal augmentation with custom-made silicone implants is a simple, safe, and inexpensive method that can readily improve the lateral profile of a patient with normal occlusion. When combined with other aesthetic procedures, paranasal augmentation can synergistically improve outcome and lead to greater patient satisfaction.

To evaluate the efficacy and safety of modified pedicle subtraction osteotomy for treatment of thoracolumbar old fracture with kyphosis.
 Methods: From January 2003 to January 2013, 58 patients of thoracolumbar kyphosis, who underwent modified pedicle subtraction osteotomy, were reviewed. Among them, 45 cases underwent initial operation and 13 cases underwent revision surgery. Preoperative and postoperative kyphotic Cobb's angle, score of back pain, as well as the incidence of complication were accessed by using visual analogue scale (VAS) and Oswestry disability index (ODI).
 Results: Mean follow-up duration was 42 months (range, 24-60 months). Average operative time was 258 min (range, 190-430 min), while average bleeding was 950 mL (range, 600-1 600 mL). All the patients were significantly improved in function and self-image, and achieved kyphosis correction with 17.9°± 4.3°. VAS of low back pain was decreased by 3.1±0.6; ODI was dropped by 25.3%±5.5%. 3 patients (5.2%) suffered anterior thigh numbness and got recovery after 3 months of follow-up. Complications happened in 19 patients, including 12 with cerebrospinal fluid leak, 4 with superficial wound infection, and 3 with urinary tract infection. All these complications were managed properly and none of them underwent reoperation.
 Conclusion: Modified pedicle subtraction osteotomy is a safe and effective technique for the treatment of old fracture with kyphosis.

BACKGROUND: A schwannoma is a benign, slow-growing peripheral nerve sheath tumor that originates from Schwann cells. Orbital schwannomas are rare, accounting for only 1% of all orbital neoplasms. In this study, we retrospectively review orbital schwannomas and characterize clinical, radiologic, and histologic features of this rare entity. METHODS: A retrospective review was performed to identify patients with histologically confirmed orbital schwannoma, among a list of 437 patients who had visited our hospital with soft tissue masses within the orbit as the primary presentation between 2010 and 2014. Patient charts and medical records were reviewed for demographic information, relevant medical and family history, physical examination findings relating to ocular and extraocular sensorimotor function, operative details, postoperative complications, pathologic report, and recurrence. RESULTS: Five patients (5/437, 1.1%) were identified as having histologically confirmed orbital schwannoma and underwent complete excision. Both computed tomography (CT) and magnetic resonance imaging (MRI) studies were not consistent in predicting histologic diagnosis. There were no complications, and none of the patients experienced significant scar formation. In two cases, patients exhibited a mild postoperative numbness of the forehead, but the patients demonstrated full recovery of sensation within 3 months after the operation. None of the five patients have experienced recurrence. CONCLUSION: Orbital schwannomas are relatively rare tumors. Preoperative diagnosis is difficult because of its variable presentation and location. Appropriate early assessment of orbital tumors by CT or MRI and prompt management is warranted to prevent the development of severe complications. Therefore, orbital schwannomas should be considered in the differential diagnosis of slow-growing orbital masses.

Melorheostosis is a rare, progressive bone disease accompanied by hyperostosis and soft tissue fibrosis. While affected adults present with contracture and pain, children present with limb length discrepancy and deformity. We report the case of a 20-year-old woman with melorheostosis since childhood who presented with right hand deformity and numbness. Radiographs showed not only a combination of dense sclerosis and opacities, but also the classic 'flowing candle wax' appearance. Radiography can be used to identify melorheostosis, thus preventing unnecessary bone biopsies. Carpal tunnel release revealed the presence of a thickened flexor retinaculum and a degenerated median nerve distal to the retinaculum, but did not show hyperostosis. This case highlights the role of nerve decompression in melorheostosis and the importance of early identification of the disease to prevent unnecessary bone biopsies.
