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.

Object Multiple surgical procedures have been described for the management of isolated nonsyndromic sagittal synostosis. Minimally invasive techniques have been recently emphasized, but these techniques necessitate the use of an endoscope and postoperative helmeting. The authors assert that a safe and effective, more “minimalistic” approach is possible, avoiding the use of endoscopic visualization and routine postoperative application of a cranial orthosis. Methods A single-institution cohort analysis was performed on 18 cases involving infants treated for isolated nonsyndromic sagittal synostosis between 2008 and 2010 using a nonendoscopic, minimally invasive calvarial vault remodeling (CVR) procedure without postoperative helmeting. The surgical technique is described. Variables analyzed were: age at time of surgery, sex, estimated blood loss (EBL), operative time, intraoperative complications, postoperative complications, length of stay, pre- and postoperative cephalic index (CI), clinical impressions, and results of a 5-question nonstandardized questionnaire administered to patient caregivers regarding outcome. Results Eleven male and 7 female infants (mean age 2.3 months) were included in the study. The mean duration of follow-up was 16.4 months (range 6–38 months). The mean procedural time was 111 minutes (range 44–161 minutes). The mean length of stay was 2.3 days (range 2–3 days). The mean EBL in all 18 patients was 101.4 ml (range 30–475 ml). One patient had significant bone bleeding resulting in an EBL of 475 ml. Excluding this patient, the mean EBL was 79.4 ml (range 30–150 ml). There were no deaths or intraoperative complications; one patient had a superficial wound infection. The mean CI was 69 preoperatively versus 79 postoperatively, a statistically significant difference (p < 0.0001). Two patients were offered helmeting for suboptimal surgical outcome; one family declined and the single helmeted patient showed improvement at 2 months. No patient has undergone further surgery for correction of primary deformity, secondary deformities, or bony irregularities. Complete questionnaire data were available for 14 (78%) of the 18 patients; 86% of the respondents were pleased with the cosmetic outcome, 92% were happy to have avoided helmeting, 72% were doubtful that helmeting would have provided more significant correction, and 86% were doubtful that further surgery would be necessary. Small, palpable, aesthetically insignificant skull irregularities were reported by family members in 6 cases (43%). Conclusions The authors present a nonendoscopic, minimally invasive CVR procedure without postoperative helmeting. Their small series demonstrates this to be a safe and efficacious procedure for isolated nonsyndromic sagittal synostosis, with improvements in CI at a mean follow-up of 16.1 months, commensurate with other techniques, and with overall high family satisfaction. Use of a CVR cranial orthosis in a delayed fashion can be effective for the infrequent patient in whom this approach results in suboptimal correction.

Skull Base Meningiomas

OBJECTIVEAnterior skull base meningiomas are benign lesions that cause neurological symptoms through mass effect on adjacent neurovascular structures. While traditional transcranial approaches have proven to be effective at removing these tumors, minimally invasive approaches that involve using an endoscope offer the possibility of reducing brain and nerve retraction, minimizing incision size, and speeding patient recovery; however, appropriate case selection and results in large series are lacking.METHODSThe authors developed an algorithm for selecting a supraorbital keyhole minicraniotomy (SKM) for olfactory groove meningiomas or an expanded endoscopic endonasal approach (EEA) for tuberculum sella (TS) or planum sphenoidale (PS) meningiomas based on the presence or absence of olfaction and the anatomical extent of the tumor. Where neither approach is appropriate, a standard transcranial approach is utilized. The authors describe rates of gross-total resection (GTR), olfactory outcomes, and visual outcomes, as well as complications, for 7 subgroups of patients. Exceptions to the algorithm are also discussed.RESULTSThe series of 57 patients harbored 57 anterior skull base meningiomas; the mean tumor volume was 14.7 ± 15.4 cm3 (range 2.2–66.1 cm3), and the mean follow-up duration was 42.2 ± 37.1 months (range 2–144 months). Of 19 patients with olfactory groove meningiomas, 10 had preserved olfaction and underwent SKM, and preservation of olfaction in was seen in 60%. Of 9 patients who presented without olfaction, 8 had cribriform plate invasion and underwent combined SKM and EEA (n = 3), bifrontal craniotomy (n = 3), or EEA (n = 2), and one patient without both olfaction and cribriform plate invasion underwent SKM. GTR was achieved in 94.7%. Of 38 TS/PS meningiomas, 36 of the lesions were treated according to the algorithm. Of these 36 meningiomas, 30 were treated by EEA and 6 by craniotomy. GTR was achieved in 97.2%, with no visual deterioration and one CSF leak that resolved by placement of a lumbar drain. Two patients with tumors that, based on the algorithm, were not amenable to an EEA underwent EEA nonetheless: one had GTR and the other had a residual tumor that was followed and removed via craniotomy 9 years later.CONCLUSIONSUtilizing a simple algorithm aimed at preserving olfaction and vision and based on maximizing use of minimally invasive approaches and selective use of transcranial approaches, the authors found that excellent outcomes can be achieved for anterior skull base meningiomas.

<p><b>Objective:</b> We retrospectively evaluated the results of an edge-to-edge repair (Alfieri stitch) of the mitral valve performed via a transaortic approach in patients who were undergoing minimally invasive aortic valve replacement.</p><p><b>Methods:</b> From January 2010 to September 2010, 6 patients underwent minimally invasive edge-to-edge repair of the mitral valve via a transaortic approach with concomitant aortic valve replacement. The patients were considered to be candidates for this procedure if they were deemed by the surgeon to be high-risk for a double valve procedure and if on preoperative transesophageal echocardiogram the mitral regurgitation jet originated from the middle portion (A2/P2 segments) of the mitral valve.</p><p><b>Results:</b> There was no operative mortality. Mean cardiopulmonary bypass time was 137 minutes, and mean cross-clamp time was 111 minutes. There was a significant improvement in the mean mitral regurgitation grade, with a mean of 3.8 preoperatively and 0.8 postoperatively. The ejection fraction remained stable, with mean preoperative and postoperative ejection fractions of 43.3% and 47.5%, respectively. Follow-up transthoracic echocardiograms obtained at a mean of 33 days postoperatively (range, 8-108 days) showed no significant worsening of mitral regurgitation.</p><p><b>Conclusion:</b> Transaortic repair of the mitral valve is feasible in patients undergoing minimally invasive aortic valve replacement.</p>

Objective. To review the existing studies on single-site robotic myomectomy and test the safety and feasibility of this innovative minimally invasive technique. Data Sources. PubMed, Scopus, Google Scholar (from their inception to October 2019), as well as Clinicaltrials.gov databases up to April 2020. Methods of Study Selection. Clinical trials (prospective or retrospective) that reported the outcomes of single-site robotic myomectomy, with a sample of at least 20 patients were considered eligible for the review. Results. The present review was performed in accordance with the guidelines for Systematic Reviews and Meta-Analyses (PRISMA). Four (4) studies met the inclusion criteria, and a total of 267 patients were included with a mean age from 37.1 to 39.1 years and BMI from 21.6 to 29.4 kg/m2. The mean operative time ranged from 131.4 to 154.2 min, the mean docking time from 5.1 to 5.45 min, and the mean blood loss from 57.9 to 182.62 ml. No intraoperative complications were observed, and a conversion rate of 3.8% was reported by a sole study. The overall postoperative complication rate was estimated at 2.2%, and the mean hospital stay ranged from 0.57 to 4.7 days. No significant differences were detected when single-site robotic myomectomy was compared to the multiport technique concerning operative time, blood loss, and total complication rate. Conclusion. Our findings support the safety of single-site robotic myomectomy and its equivalency with the multiport technique on the most studied outcomes. Further studies are needed to conclude on the optimal minimally invasive technique for myomectomy.

Background: The objective of this study was to report the results of a new minimally invasive Achilles reconstruction technique and to assess the perioperative morbidity, medium- to long-term outcomes, and functional results. Methods: Our series was comprised 14 patients (11 men and 3 women), with a mean age of 45.6 years at surgery. Each patient had a chronic Achilles tendon rupture. The mean interval from rupture to surgery was 5.5 months (range, 2-10). The mean total follow-up was 30.1 months (range, 12-78). All patients were operated with a central turndown flap augmented with free semitendinosus tendon graft and percutaneous sutures in a minimally invasive approach assisted by endoscopy. The patients underwent retrospective assessment by clinical examination, the American Orthopaedic Foot & Ankle Society (AOFAS) ankle and hindfoot score, and the Achilles Tendon Total Rupture Score (ATRS). Paired t tests were used to assess the preoperative and postoperative AOFAS scores, ATRS scores, and ankle range of motion. Results: The length of the defect ranged from 3 to 8 cm (mean, 5.1), while the length of the turndown flap ranged from 8 to 13 cm (mean, 10.1). The mean AOFAS score improved from 64.5 points preoperatively to 96.9 points at last follow-up. The mean ATRS score improved from 49.4 preoperatively to 91.4 points at last follow-up. None of the patients developed a wound complication. No patient had a rerupture or sural nerve damage. Conclusion: All patients in our study had a favorable outcome with no complications. We believe that with this triple-repair technique, one can achieve a strong and robust repair such as in open surgery while at the same time reducing the incidence of complications. Level of Evidence: Level III, retrospective comparative study.

AimsThe aim of this study was to describe, analyze, and compare the survival, functional outcome, and complications of minimally invasive (MI) and non-invasive (NI) lengthening total femoral prostheses.Patients and MethodsA total of 24 lengthening total femoral prostheses, 11 MI and 13 NI, were implanted between 1991 and 2016. The characteristics, complications, and functional results were recorded. There were ten female patients and ten male patients. Their mean age at the time of surgery was 11 years (2 to 41). The mean follow-up was 13.2 years (seven months to 29.25 years). A survival analysis was performed, and the failures were classified according to the Modified Henderson System.ResultsThe overall implant survival was 79% at five, ten, and 20 years for MI prostheses, and 84% at five years and 70% at ten years for NI prostheses. At the final follow-up, 13 prostheses did not require further surgery. The overall complication rate was 46%. The mean revision-free implant survival for MI and NI prostheses was 59 months and 49 months, respectively. There were no statistically significant differences in the overall implant survival, revision-free survival, or the distribution of complications between the two types of prosthesis. Infection rates were also comparable in the groups (9% vs 7%; p = 0.902). The rate of leg-length discrepancy was 54% in MI prostheses and 23% in NI prostheses. In those with a MI prosthesis, there was a smaller mean range of movement of the knee (0° to 62° vs 0° to 83°; p = 0.047), the flexion contracture took a longer mean time to resolve after lengthening (3.3 months vs 1.07 months; p < 0.001) and there was a lower mean Musculoskeletal Tumor Society (MSTS) score (24.7 vs 27; p = 0.295).ConclusionThe survival and complications of MI and NI lengthening total femoral prostheses are comparable. However, patients with NI prosthesis have more accurate correction of leg-length discrepancy, a better range of movement of the knee and an improved overall function.

Valve Implantation

Objective Aortic valve replacement in minimally invasive approach has shown to improve clinical outcomes even with a prolonged cardiopulmonary bypass and aortic cross-clamp (ACC) time. Sutureless aortic valve implantation may ideally shorten operative time. We describe our initial experience with the sutureless 3f Enable (Medtronic, Inc, ATS Medical, Minneapolis, MN USA) aortic bioprosthesis implanted in minimally invasive approach in high-risk patients. Methods Between May 2010 and May 2011, thirteen patients with severe aortic stenosis underwent aortic valve replacement with the 3f Enable bioprosthesis through an upper V-type ministernotomy interrupted at the second intercostal space. The mean ± SD age was 77 ± 3.9 years (range, 72–83 years), 10 patients were women, and the mean ± SD logistic EuroSCORE was 15% ± 13.5%. Echocardiography was performed preoperatively, at postoperative day 1, at discharge, and at follow-up. Clinical data, adverse events, and patient outcomes were recorded retrospectively. The median follow-up time was 4 months (interquartile range, 2–10 months). Results Most of the implanted valves were 21 mm in diameter (19–25 mm). The CPB and ACC times were 100.2 ± 25.3 and 66.4 ± 18.6 minutes. At short-term follow-up, the mean ± SD pressure gradient was 14 ± 4.9 mm Hg; one patient showed trivial paravalvular leakage. No patients died during hospital stay or at follow-up. Conclusions The 3f Enable sutureless bioprosthesis implanted in minimally invasive approach through an upper V-type ministernotomy is a feasible, safe, and reproducible procedure. Hemodynamic and clinical data are promising. This innovative approach might be considered as an alternative in high-risk patients. Reduction of CPB and ACC time is possible with increasing of experience and sutureless evolution of actual technology.

OBJECTIVELumbar disc herniation (LDH) in the pediatric population is rare and exhibits unique characteristics compared with adult LDH. There are limited data regarding the safety and efficacy of minimally invasive surgery (MIS) using tubular retractors in pediatric patients with LDH. Here, the outcomes of MIS tubular microdiscectomy for the treatment of pediatric LDH are evaluated.METHODSTwelve consecutive pediatric patients with LDH were treated with MIS tubular microdiscectomy at the authors’ institution between July 2011 and October 2015. Data were gathered from retrospective chart review and from mail or electronic questionnaires. The Macnab criteria and the Oswestry Disability Index (ODI) were used for outcome measurements.RESULTSThe mean age at surgery was 17 ± 1.6 years (range 13–19 years). Seven patients were female (58%). Prior to surgical intervention, 100% of patients underwent conservative treatment, and 50% had epidural steroid injections. Preoperative low-back and leg pain, positive straight leg raise, and myotomal leg weakness were noted in 100%, 83%, and 67% of patients, respectively. The median duration of symptoms prior to surgery was 9 months (range 1–36 months). The LDH level was L5–S1 in 75% of patients and L4–5 in 25%. The mean ± SD operative time was 90 ± 21 minutes, the estimated blood loss was ≤ 25 ml in 92% of patients (maximum 50 ml), and no intraoperative or postoperative complications were noted at 30 days. The median hospital length of stay was 1 day (range 0–3 days). The median follow-up duration was 2.2 years (range 0–5.8 years). One patient experienced reherniation at 18 months after the initial operation and required a second same-level MIS tubular microdiscectomy to achieve resolution of symptoms. Of the 11 patients seen for follow-up, 10 patients (91%) reported excellent or good satisfaction according to the Macnab criteria at the last follow-up. Only 1 patient reported a fair level of satisfaction by using the same criteria. Seven patients completed an ODI evaluation at the last follow-up. For these 7 patients, the mean ODI low-back pain score was 19.7% (SEM 2.8%).CONCLUSIONSTo the authors’ knowledge, this is the longest outcomes study and the largest series of pediatric patients with LDH who were treated with MIS microdiscectomy using tubular retractors. These data suggest that MIS tubular microdiscectomy is safe and efficacious for pediatric LDH. Larger prospective cohort studies with longer follow-up are needed to better evaluate the long-term efficacy of MIS tubular microdiscectomy versus other open and MIS techniques for the treatment of pediatric LDH.

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.
