Abstract BACKGROUND: Lead migration is a significant concern with spinal cord stimulator (SCS) placement with rates ranging from 10% to 60%. OBJECTIVE: To describe a novel technique using bone cement at the laminotomy site to help prevent lead migration after minimally invasive placement of laminectomy paddle leads and to present our short-term results. METHODS: A review of a prospectively maintained database identified all patients who underwent minimally invasive placement of laminectomy leads with the use of bone cement. All procedures were performed between July 2008 and August 2010 with conscious sedation and local anesthetic. Intraoperative testing was performed to confirm good pain coverage. A small volume of bone cement (1–3 cm3) was then placed to cover the laminectomy defect. Radiographic and clinical follow-up was assessed. RESULTS: Forty-two patients (mean age, 58.0 years) underwent 42 procedures. Back pain (88.1%) and leg pain (88.6%) were the most common presenting symptoms. No intraoperative complications were noted. Two patients (4.8%) required removal of their devices because of nonhealing wounds. All patients were followed up for a minimum of 6 months, and no cases of clinical or radiographic lead migration were seen at the time of publication. CONCLUSION: We present a novel technique in the hopes of decreasing the incidence of lead migration after minimally invasive placement of spinal cord stimulator laminectomy paddle leads. Our results have been promising thus far with no cases of lead migration.

Objectives: Imperforate hymen (IH) is a common genital tract anomaly in women which usually presents after puberty. However, surgical treatment is often considered controversial in religious or conservative communities for sociocultural reasons. This study therefore aimed to assess the efficacy of a novel reconstructive technique involving the preservation of the annular hymen. Methods: This prospective interventional study was performed between July 2013 and October 2019 at the minimally invasive surgery unit of a tertiary university hospital in Egypt. A total of 36 women presenting with primary amenorrhoea and haematocolpus were diagnosed with postpubertal IH. A circular hymenotomy was performed on each patient using a 10 mm laparoscopy trocar tip and sleeve to form a new annular hymen under general anaesthesia while preserving the annular hymen. The primary outcome measure was the persistence of hymenal patency and integrity at follow-up. The secondary outcome measure included post-operative patient satisfaction and pain relief. Results: The reported technique was feasible in all cases without intraoperative complications. Patency of the reconstructed annular hymen was confirmed at follow-up in all cases; moreover, no intraoperative complications were reported. There was a significant post-operative improvement in pain scores (P <0.001). Both the patients and their parents/guardians reported a high level of satisfaction with the technique. Conclusion: This novel technique for the correction of IH involving the reconstruction of an annular hymen was found to be a safe, minimally invasive and effective procedure. This technique should be considered a feasible alternative to a conventional hymenotomy as it allows for the resumption of normal hymenal anatomy without overtreatment.   KEYWORDS Congenital Abnormalities; Imperforate Hymen; Hematocolpos; Amenorrhea; Colpotomy; Reconstructive Surgical Procedures; Treatment Outcome; Egypt.

✓ The authors describe a novel technique for the implantation of multipolar epidural spinal cord neurostimulator electrodes with the aid of a tubular retractor system. Spinal cord neurostimulation is used as a neuroaugmentive tool for treating chronic intractable pain syndromes. Minimally invasive placement of the multipolar neurostimulator electrodes may allow for shorter hospital stays and less postoperative pain associated with the incision.

Object Lateral mass screws are traditionally used to fixate the subaxial cervical spine, while pedicle screws are used in the thoracic spine. Lateral mass fixation at C-7 is challenging due to thin facets, and placing pedicle screws is difficult due to the narrow pedicles. The authors describe their clinical experience with a novel technique for transfacet screw placement for fixation at C-7. Methods A retrospective chart review was undertaken in all patients who underwent transfacet screw placement at C-7. The technique of screw insertion was the same for each patient. Polyaxial screws between 8- and 10-mm-long were used in each case and placed through the facet from a perpendicular orientation. Postoperative radiography and clinical follow-up were analyzed for aberrant screw placement or construct failure. Results Ten patients underwent C-7 transfacet screw placement between June 2006 and March 2007. In all but 1 patient screws were placed bilaterally, and the construct lengths ranged from C-3 to T-5. One patient with a unilateral screw had a prior facet fracture that precluded bilateral screw placement. There were no intraoperative complications or screw failures in these patients. After an average of 6 months of follow-up there were no hardware failures, and all patients showed excellent alignment. Conclusions The authors present the first clinical demonstration of a novel technique of posterior transfacet screw placement at C-7. These results provide evidence that this technique is safe to perform and adds stability to cervicothoracic fixation.

Lumboiliac or lumbar hernia is a rare defect in the posterolateral abdominal wall that may be inadvertently misidentified and interfere with the implantable pulse generator (IPG) portion of spinal cord stimulator (SCS) implants. We report the case of a 54-year-old Caucasian man with an incidental finding of a lumboiliac hernia in the inferior lumbar triangle of Petit with placement of an IPG in a SCS implant. With the assistance of surgical colleagues, the correct diagnosis was made intraoperatively. We describe the operative repair of the lumboiliac hernia with a synthetic mesh. A new IPG pocket was created above the mesh prior to proceeding with IPG placement. No recurrence of the hernia defect was observed on 2-month follow-up. It is important that pain physicians and neurosurgeons who perform SCS implants are aware of lumboiliac hernias to avoid potential diagnostic or management errors. Lumboiliac hernias should be included on the differential diagnosis of lumbar or flank masses. Confirmation with imaging may be necessary and definitive surgical treatment should be pursued.

Abstract Background The incidence of recurrent laryngeal nerve (RLN) injury after esophagectomy can be as high as 60–70% especially when lymphadenectomy is performed along bilateral RLN. Vocal cord paralysis is associated with increased pulmonary complication rate, longer hospital stay, and impaired quality-of-life. The authors have modified the Continuous Intraoperative Nerve Monitoring (CIONM) method for minimally invasive esophagectomy. This study reviews our experience in the first 102 patients. Methods From May 2014 to January 2018, patients who underwent thoracoscopic esophagectomy were recruited. CIONM and intermittent nerve stimulation were routinely used during left RLN lymphadenectomy. For right RLN dissection, only intermittent nerve stimulation was used because of much lower chance of nerve injury. Routine direct laryngoscopy was performed on postoperative day one to assess the vocal cord status. Patients with RLN palsy are referred to otorhinolaryngologist for assessment and treatment. Surgical outcome, especially RLN palsy and recovery rates were documented. Results 102 patients were recruited and 73 patients had more than one year follow up. Twenty-two patients had RLN palsy (21.6%); right side in 3, left side in 18, and bilateral in one. Thirty-eight patients (37%) had only unilateral or no RLN dissection performed. This was because of R2 resection negating the benefits of RLN dissection (15.6%), poor pulmonary exposure (9.8%), other technical difficulties (7.8%), preoperative vocal cord palsy (2%), intraoperative complications (1%) and uncertain contralateral nerve integrity (1%). For those 90 patients with successful CIONM, 20 RLN palsy (22.2%), 10 of whom underwent injection thyroplasty within 2–80 days. Thyroplasty was not performed in 12 patients as they had good compensation from the contralateral cord (58.3%), early recovery within 2 weeks (16.7%) tracheostomized status (16.7%) or refusal (8.3%). Thirteen patients (59%) recovered within 2–72 weeks (Median 6 weeks). For the 73 patients with more than 1 year follow up, only 4 has residual vocal cord paralysis, making a genuine cord palsy rate of 5.5%. Conclusion Lymphadenectomy along bilateral RLN is technically demanding. CIONM is a sensitive tool to guide surgeons for safer dissection. Proper patient selection, postoperative assessment and treatment protocol can reduce the morbidity of RLN injury. Majority of the vocal cord paralysis is temporary Disclosure All authors have declared no conflicts of interest.

Abstract: Introduction: Malignant tumours of the sinonasal region – including those with invasion of the skull base – necessitate surgical resection. The majority of the cases give an opportunity to perform the procedure via minimally invasive, endoscopic approach, without external, craniofacial surgery. Aim: To assess our clinical experience in treating anterior skull base malignancies, performing minimally invasive endoscopic transcribriform resection. Method: Between February 2015 and July 2017, four male and one female patient underwent minimally invasive, endoscopic skull base procedure. The mean age was 64.6 years (59–70, median: 66). Every surgery was performed via transnasal, endoscopic transcribriform approach. In two cases Kadish C esthesioneuroblastomas, while in one case a T3N0 sinonasal non-differentiated carcinoma, a T1N0 intestinal type adenocarcinoma and a T4N0 squamous cell carcinoma was the indication of surgery, respectively. Results: The mean follow-up time was 22.8 months, between 14 and 46 months. Intraoperative complications did not occur during the procedures. Regarding the postoperative period, liquorrhoea and pneumocephalus occurred in one case. Complications were solved with lumbar drainage. During follow-up, neither residual nor recurrent tumour was observed in our patients. Conclusion: Endoscopic transcribriform resection of the skull base malignancies is a safe and viable alternative to the traditional open approach. Orv Hetil. 2019; 160(40): 1584–1590.
