OBJECTIVE:
To explore the feasibility and key technology of microscopic resection of lumbar intraspinal tumor through microchannel keyhole approach.
METHODS:
The clinical features, imaging characteristics and surgical methods of 54 cases of lumbar intraspinal tumor which were microscopically operated by microchannel from February 2017 to September 2019 were reviewed and analyzed. There were 8 cases of extradural tumor, 3 cases of extra-and intradural tumor and 43 cases of subdural extramedullary tumor (including 3 cases of ventral spinal tumor). The tumors were 0.5-3.0 cm in diameter. The clinical symptoms included 49 cases of pain in the corresponding innervation area, 5 cases of sensory disturbance (numbness) at or below the tumor segment, 7 cases of limb weakness and 2 cases of urination and defecation dysfunction.
RESULTS:
In the study, 37 tumors were resected through hemilaminectomy, 14 tumors were resected through interlaminar fenestration, 3 tumors were resected through hemilaminectomy or interlaminar fenestration combined with facetectomy of medial 1/4 facet. All of the 54 tumors were totally resected. The operation time was 75-135 min, with an average of 93.3 min. The postoperative hospital stay was 4-7 days, with an average of 5.7 days. Postoperative pathology included 34 cases of schwannoma, 4 cases of meningioma, 9 cases of ependymoma, 1 case of enterogenous cyst, 5 cases of teratoma/epidermoid/dermoid cyst, and 1 case of paraganglioma. No infection or cerebrospinal fluid leakage was found after operation. No neurological dysfunction occurred except 1 case of urination dysfunction and 4 cases of limb numbness. The follow-up period ranged from 3 to 33 months with an average of 14.4 months. Five patients with new onset symptoms returned to normal. The pain symptoms of 49 patients were completely relieved; 4 of 5 patients with hypoesthesia recovered completely, the other 1 patient had residual mild hypoesthesia; 7 patients with limb weakness, and 2 patients with urination and defecation dysfunction recovered to normal. No spinal instability or deformity was found, and no recurrence or residual tumors were found. According to McCormick classification, they were of all grade Ⅰ.
CONCLUSION
The lumbar intraspinal extramedullary tumors within two segments (including the ventral spinal tumors) can be totally resected at stage Ⅰ through microchannel keyhole approach with appropriate selection of the cases. Microchannel technique is beneficial to preserve the normal structure and muscle attachment of lumbar spine, and to maintain the integrity and stability of lumbar spine.

Macroglossia can create dental and skeletal instability after orthodontic treatment or orthognathic surgery for mandibular prognathism. In relevant literature, partial glossectomy is suggested for a good post-treatment prognosis. Most of the published partial glossectomy cases are two-staged surgery, because of concern about postoperative airway obstruction. As orthognathic surgical techniques and fixation method develop, however, concerns about postoperative airway obstruction have lessened. In this case, mandibular setback surgery and partial glossectomy were performed simultaneously, leading to stable recovery without any postoperative respiratory problems. After surgical technique to preserve the tongue tip, we achieved good outcomes without postoperative side effects of lingual hypoesthesia, pronunciation disorder and dyskinesia. We report this case with a literature review.

PURPOSE: It is known that the chronic absence of unilateral breast can cause spine curvature. The artificial breast manufactures take up the position of that possibility. This study was designed to evaluate the influence of the mastectomy on the spine and appearance of scoliosis among women who wanted delayed breast reconstruction. ted delayed breast reconstruction. METHODS: The study population consisted of 47 women who underwent delayed breast reconstruction at our Department of Plastic Surgery from April 2001 to May 2007. The whole spine anteroposterior and lateral X-ray was taken to evaluate the Cobb's angle. As a general rule a Cobb angle of 10 is regarded as a minimum angulation to define scoliosis. We evaluated Cobb's angle and drew a correlation between the duration of the mastectomy state and the weight of the mastectomy specimen. RESULTS: There were no family history of scoliosis, and no numbness or weakness in the upper or lower extremities. They had normal reflex and experienced no tenderness of the perispinal area. The Spearman Correlation Coefficient between Cobb's angle and the period that took time from the mastectomy to the X- rays and analysis between Cobb's angle and specimen weight was 0.032 and-0.115. there were no correlation between Cobb's angle and time, or between Cobb's angle and specimen weight. CONCLUSION: lthough the patients attribute their back pain and distorted posture to having received an one- sided mastectomy, it is unlikely that one-sided mastectomy causes spinal deformity and scoliosis.

PURPOSE: Surgery for thyroid disease requires skin incisions that can result in postsurgical problems, such as prominent scars, adhesions and hypesthesia, as well as paresthesia of the neck. To overcome these problems we performed a gasless endoscopic thyroidectomy via an axillary approach. METHODS: Between November 2001 and April 2005, 141 patients underwent a gasless endoscopic thyroidectomy via an axillary approach. The surgical outcomes were evaluated in terms of the operating time, length of hospital stay and the incidence of perioperative complications. Patient opinions were assessed using a verbal response scale at two and four months after surgery. RESULTS: The mean operating time and length of hospital stay were 122.7+/-32.8 minutes and 3.4+/-0.9 days, respectively. No cases required either conversion to open surgery or involved significant intraoperative complications. Two months after surgery, 75 patients (53.2%) complained of hypesthesia or paresthesia in the anterior chest wall. The number of patients with such complaints (9.9%) had decreased 4 months after surgery (P<0.001). Four months after surgery, only 4 patients (2.8%) complained of hypesthesia or paresthesia in the neck, and 10 (7.1%) complained of discomfort while swallowing. All patients were satisfied with the cosmetic results. CONCLUSION: A gasless endoscopic thyroidectomy via an axillary approach is feasible and safe, and provides excellent cosmetic results, with a minimal degree of postoperative complaints. This procedure provides another surgical option for the treatment of benign thyroid disease in selected patients.

OBJECTIVE:
To evaluate clnical effect of minimally invasive osteotomy with absorbable screws in treating hallux valgus deformity.
METHODS:
Clnical data of 31 patients with hallux valgus deformity were retrospective analyzed from January 2019 to December 2020, and divided into absorbable screws group (17 patients) and titanium cannulated screw group (14 patients). In absorbable screws group, there were 1 male and 16 females aged from 32 to 72 years old with an average of (54.53±12.12) years old;6 patients on the left side, 5 on bilateral and 6 on the right side;1 patient was mild, 11 moderate and 5 severe;treated with minimally invasive osteotomy and fixation of absorbable screws. In titanium cannulated screw group, there were 2 males and 12 females aged from 18 to 71 years old with an average of (47.57±15.68) years old;4 patients on the left side, 4 on bilateral and 6 on the right side;1 patient was mild, 9 moderate and 4severe;treated with minimally invasive osteotomy and fixation of titanium cannulated screw. Complications between two groups were observed, changes of hallux valgus angle (HVA)and intermetatarsal angle (IMA)were detected and compared before and after operation at 12 months, American Orthopedic Foot and Ankle Society(AOFAS) and visual analogue scale(VAS) before and after operation at 12 months were also compared.
RESULTS:
All 31 patients were followed up from 13 to 20 months with an average of (16.61±2.47) months. Patients in absorbable screws group were followed up from 14 to 20 months with an average of (16.88±2.80) months, while patients in titanium cannulated screw group were followed up from 13 to 19 months with an average of (16.29±2.05) months;there was no difference between two groups(P>0.05). One patient in absorbable screws group occurred numbness around incision, 3 patients in titanium cannulated screw group occurred complications, including numbness around incision in 1 patient, skin irritation due to internal fixation in 1 patient, and recurrence in 1 case;there was no statistic difference between two groups (χ2=1.651, P=0.199). There were no statistic difference in HVA and IMA between two groups before and after operation at 12 months(P>0.05). There were no statistic difference between two groups in AOFAS and VAS before and after operation at 12 months(P>0.05).
CONCLUSION
Compare with mainstream fixation with titanium hollow screw after minmally invasive osteotomy, fixation with absorbable screw could achieve comparable clinical outcome on the basis of images and function evaluation.

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.

BACKGROUND: Good postoperative pain control is an important part of adequate postoperative care. Patient-controlled epidural analgesia (PCEA) provided better postoperative analgesia compared to other conventional analgesic methods, but several risks have been observed as well. We therefore surveyed the efficacy and safety of PCEA in this retrospective observational study. METHODS: We analyzed collected data on 2,276 elective surgical patients who received PCEA with ropivacaine and fentanyl. Patients were assessed by a PCA service team in the post-anesthesia care unit (PACU), at 1-6 h, 6-24 h, and 24-48 h postoperatively for adequate pain control. The presence of PCEA-related adverse events was also assessed. RESULTS: Numerical pain score (median [interquartile range]) were 3 [1-4], 5 [4-7], 4 [3-5], and 3 [3-5] in the PACU, at 1-6 h, 6-24 h, and 24-48 h postoperatively. Median pain scores in patients underwent major abdominal or thoracic surgery were higher than other surgical procedure in the PACU, at 1-6 h after surgery. Nausea and vomiting (20%) and numbness and motor weakness (15%) were revealed as major PCEA-related adverse events during the postoperative 48 h period. There were 329 patients (14%) for whom PCEA was ceased within 48 h following surgery. CONCLUSIONS: Our data suggest that the use of PCEA provides proper analgesia in the postoperative 48 h period after a wide variety of surgical procedures and that is associated with few serious complications. However, more careful pain management and sustainable PCEA monitoring considering the type of surgical procedure undergone is needed in patients with PCEA.

PURPOSE: Surgery for thyroid disease requires a skin incision that can result in postsurgical problems such as prominent scars, adhesions, hypesthesia, and paresthesia in the neck. To overcome these problems, we performed a gasless endoscopic thyroidectomy via an axillary approach. METHODS: Between May 2004 and April 2005, 30 female patients underwent gasless endoscopic thyroidectomy via an axillary approach. Surgical outcomes were evaluated in terms of operating time, length of hospital stay, and the incidence of perioperative complications. Patient opinion was assessed using a verbal response scale at two and four months after surgery. RESULTS: The mean operating time was 126.8±32.4 minutes, and the mean length of hospital stay was 4.3±1.1 days. No cases required conversion to open surgery and none involved significant intraoperative complications. Three patients (10.0%) complained slight hypesthesia or paresthesia in the anterior chest wall, and only 2 patients (6.7%) complained the discomfort while they were swallowing for 4 months after surgery. All patients were satisfied with the cosmetic results. CONCLUSION: Gasless endoscopic thyroidectomy via an axillary approach is feasible and safe and provides excellent cosmetic results with a minimal degree of postoperative complaints. This procedure provides another surgical option for the treatment of benign thyroid disease in selected patients.

Bednar tumor was described by Bednar in 1957. The histologic pattern of this tumor shows similar to dermatofibrosarcoma protuberans (DFSP) but melanin pigments are scattered within the tumor, It's rare neoplasm accounting for approximately 1-5% of all case of DFSP. Clinically, this tumor is considered to be intermediated malignancy, because of slow growth and frequent local recurrence and lack of distant metastasis. The majority are located on the trunk and the upper and lower extremities, but extremely rate in the head and neck area. Microscopically, this tumor is characterized by tight storiform spindle cells and long slender cells that admixed with a small population of melanin containing dendritic cells. This dendritic cells are the primary features distinguising this lesion from conventional DFSP. Complete surgical excision and close follow-up case are necessany for this neoplasm because of probable intermediate malignancy. A patient was admitted to Our Department of Oral and Maxillofacial Surgery due to swelling on right parotid area and numbness of the right lower lip on September, 1994, By clinical examinations and C-T finding, we dignosed tentatively as myxoma or pleomorphic adenoma. Surgical excision of this tumor was performed with parotidectomy and mandibular osteotomy under the frozen biopsy. By final microscopic and electromicroscopic examination and immunohistochemical study, this tumor was diagnosed as Bednar tumor. So, we report a case of pigmented DFSP with review of literatures.

Clinics in Orthopedic Surgery 2010;2(4):232-236
BACKGROUND: The authors report the results of preserving the infrapatellar branch of the saphenous nerve during unicompartmental knee arthroplasty to prevent lateral skin numbness. METHODS: All 100 cases had medial compartmental osteoarthritis and a minimally invasive technique had been used. The mean follow-up duration was two years and eight months (range, 24 to 42 months). RESULTS: The classification according to the location of this nerve was observed as either Mochida Type I with 76 cases (76%), Type II with 16 cases (16%), and unclassified type with 8 cases (8%). In Type I, the nerve was saved in 62 cases (82%), but could not be preserved in Type II because of the surgical procedure. These results showed that the mean distance from the joint line to the nerve of Type I was 9.13 mm (range, 4 to 15 mm) and the nerve passed inferiorly. CONCLUSIONS: This study showed the location of this nerve can be predicted ahead of the procedure, which will help preserve it during the surgery.
