Meningiomas are benign spinal arachnoid tumours, typically presenting as intradural extramedullary (IDEM) lesions that can compress the spinal cord and require surgical intervention. Minimally invasive surgery (MIS) techniques like mini-open, tubular and endoscopic approaches minimize tissue manipulation, reduce pain and accelerate recovery. This systematic review provides insights into current practices regarding MIS for cervical meningioma and presents a case series of eight patients with cervical meningioma effectively managed by MIS.

A comprehensive literature search was conducted across Embase, PubMed and Medline Ovid, focusing on MESH terms related to cervical vertebrae, nervous system neoplasms and minimally invasive surgical procedures. Risk of bias in retained studies was assessed using the Joanna Briggs Institute Critical Appraisal tools for case series and case reports. A narrative synthesis of our results is presented.

Nine studies with 15 patients undergoing MIS for cervical meningioma were included. Most tumours were at the craniospinal junction. Gross total resection (Simpson grade 2) was achieved in 14 cases, with no reported post-operative complications. The length of stay (LOS) ranged from 2 to 6 days, and no tumour recurrence was observed. Our case series of eight patients confirmed MIS benefits, including shorter operative times, comparable surgical outcomes, and the avoidance of spinal deformities requiring instrumentation.

In well-selected patients, MIS for cervical meningioma is a safe and effective procedure offering direct lateral access, minimal bony resection, limited soft tissue manipulation, and avoidance of cervical fusion, thereby minimizing post-operative complications and LOS.

Patent ductus arteriosus is an important cause of morbidity and mortality, especially in very low birth weight infants. The aim of the study is to report our single-centre short-term results of preterm patients who underwent ligation through left anterior mini-thoracotomy .

Data of 27 preterm infants operated by the same surgeon who underwent Patent ductus arteriosus (PDA) closure with left anterior mini-thoracotomy technique between November 2020 and January 2022 at a single institution were reviewed. The patients were divided into two groups according to their weight at the time of surgery. Data on early postoperative outcomes and survival rates after discharge were collected.

Twenty-seven patients with a mean (±SD) gestational age of 25.8 (±2.0) weeks and a mean birth weight of 1027 (±423) g were operated using left anterior mini-thoracotomy technique. The lowest body weight was 480 g. Complications such as bleeding, abnormal healing of incision, or pneumothorax were not seen. There were 8 mortalities after the operation (29,6 %). The causes of the deaths were sepsis, necrotising enterocolitis, hydrops fetalis, hepatoblastoma, and intracranial bleeding. There was no statistically significant difference in the rates of complication between the groups.

Left anterior mini-thoracotomy technique can be performed as the first choice when transcatheter intervention cannot be applied in preterm infants. It provides easy access to the PDA, a good exposure, minimal contact with the lungs, good cosmetic results in early and mid-term and shortens the operation time, especially in very low birth weight preterm babies. However, early ligation may be helpful to minimise the complications related to PDA.

Large-sized clinical trials have failed to show an overall benefit of surgery over medical treatment in managing spontaneous intracerebral hemorrhages (ICH); less invasive techniques have shown to decrease brain injury caused by surgical manipulation in the standard open approach improving the clinical outcomes of patients. Thereby, we propose a low-cost 3D-printed endoport for a less invasive ICH evacuation. In this study, the authors compare the clinical outcomes of early surgical evacuation using a 3D-printed endoport vs. a standard open surgery (OS).

A retrospective analysis was conducted comparing patients who underwent early evacuation of a deep hypertensive ICH through an endoport vs. OS at a single center from August 2017 to March 2019. Demographic, clinical, and radiologic data were reviewed. The primary outcomes were the 90-day post-stroke functional outcome and mortality.

A total of 36 patients were included. The two cohorts (18 endoport; 18 OS) showed no statistically significant differences in demographic, clinical, and radiologic characteristics, including median admission hemorrhage volume, Glasgow Coma Scale, and ICH scores. At 90-day post-stroke, 44% of patients in the endoport group and 17% in the OS group had a favorable functional outcome (mRS 0–3) (p = 0.039); moreover, the endoport group showed lower mortality (33% vs. 72%, p = 0.019).

This study suggests that an endoport-assisted ICH evacuation may have better functional outcomes and lower mortality than OS. The proposed device could provide a safe, low-cost alternative for ICH’s surgical treatment. More rigorous research is hence needed to assess the potential benefits of this technique.

The mini right axillary thoracotomy is an alternative surgical approach to repair certain congenital heart defects. Quality-of-life metrics and clinical outcomes in children undergoing either the right axillary approach or median sternotomy were compared.

Patients undergoing either approach for the same defects between 2018 and 2020 were included. Demographic details, operative data, and outcomes were compared between both groups. An abbreviated quality of life questionnaire based on the Infant/Toddler/Child Health Questionnaires focused on the patient’s global health, physical activity, and pain/discomfort was administered to all parents/guardians within two post-operative years.

Eighty-seven infants and children underwent surgical repair (right axillary thoracotomy, n = 54; sternotomy, n = 33) during the study period. There were no mortalities in either group. The right axillary thoracotomy group experienced significantly decreased red blood cell transfusion, intubation, intensive care, and hospital durations, and earlier chest tube removal. Up to 1 month, parents’ perception of their child’s degree and frequency of post-operative pain was significantly less after the right axillary thoracotomy approach. No difference was found in the patient’s global health or physical activity limitations beyond a month between the two groups.

With the mini right axillary approach, surrogates of faster clinical recovery and hospital discharge were noted, with a significantly less perceived degree and frequency of post-operative pain initially, but without the quality of life differences at last follow-up. While providing obvious cosmetic advantages, the minimally invasive right axillary thoracotomy approach for the surgical repair of certain congenital heart lesions is a safe alternative to median sternotomy.

The aim of this study is to report on the short-term and mid-term outcomes of preterm infants who underwent patent ductus arteriosus ligation through anterior mini-thoracotomy.

Data for 103 preterm infants who underwent patent ductus arteriosus clipping through an anterior mini-thoracotomy at the 2nd intercostal space between 2009 and 2019 were retrospectively reviewed. The patients were divided into two groups according to their weight at the time of surgery. The complications, morbidity, and mortality rates of each group were compared at postoperative day 30 and at the end of 1 year after surgery.

During the operation, the median weight of the patients was 900 g (IQR 800–1125 g), the median age was 21 days (IQR 14.5–29 days). The lowest body weight was 460 g. In three patients (3%), there was intraoperative bleeding from the patent ductus arteriosus that required transition to median sternotomy. In one patient (1%) a residual patent ductus arteriosus that required reoperation was observed. Twelve patients (12%) died in the first 30 days postoperatively. Six patients (6%) died between the postoperative day 30 and 1 year. There was no statistically significant difference in the rates of mortality, morbidity, and complication between the groups.

Based on our observations of over a hundred preterm infants with patent ductus arteriosus over a decade, ligation through anterior mini-thoracotomy is the main surgical procedure of choice for this patient group in our clinic. Our findings demonstrate the safety of this approach and we believe that it can be successfully replicated in other institutions.

Patent ductus arteriosus closure is traditionally performed by thoracotomy approach. Video-assisted thoracoscopic surgery is a less frequently utilised alternative. We sought to compare elective surgical outcomes between the two methods via a single-centre retrospective cohort analysis.

All patients >3.2 kg undergoing surgical patent ductus arteriosus ligation at a single institution from 2000 to 2018 were retrospectively reviewed. Propensity matching for age, weight, diuretic usage, and preterm status was conducted to adjust for differences in baseline patient characteristics. Outcome measures included operative time, hospitalisation duration, post-operative complications, and re-operation.

A total of 173 patients were included, 127 thoracoscopy and 46 thoracotomy. In the unmatched cohorts, no significant difference in closure success was found (94% thoracoscopy versus 100% thoracotomy, p = 0.192). Although median operative time was longer for thoracoscopy (87 versus 56 minutes, p < 0.001), hospitalisation duration was shorter (1.05 versus 2.41 days, p < 0.001), as was ICU stay (0.00 versus 0.75 days, p < 0.001). There were no significant differences in re-operation or complication rates, except chest tube placement (11% thoracoscopy versus 50% thoracotomy, p < 0.001). After matching (69 thoracoscopy versus 20 thoracotomy), these differences persisted, including median operative time (81 versus 56 minutes, p = 0.007; thoracoscopy versus thoracotomy), hospitalisation duration (1.25 versus 2.27 days, p < 0.001), and chest tube placement (17% versus 60%, p < 0.001). There remained no significant difference in complications or re-operations.

Thoracoscopic ligation was associated with shorter ICU and hospital stays and less frequent chest tube placement, but longer operative times. Other risks, including bleeding, chylothorax, and recurrent laryngeal nerve injury, were similar.

Treatment of inflammatory and neoplastic disease in the maxillary sinus, pterygopalatine and infratemporal fossae requires appropriate surgical exposure. As modern rhinology evolves, so do the techniques available. This paper reviews extended endoscopic approaches to the maxillary sinus and the evidence supporting each technique.

A literature search of the Ovid Medline and PubMed databases was performed using appropriate key words relating to endoscopic approaches to the maxillary sinus.

Mega-antrostomy and medial maxillectomy have a role in the surgical treatment of refractory inflammatory disease and sinonasal neoplasms. The pre-lacrimal fossa approach provides excellent access but can be limited because of anatomical variations. Both the transseptal and endoscopic Denker's approaches were reviewed; these appear to be associated with morbidity, without any significant increase in exposure over the afore-described approaches.

A range of extended endoscopic approaches to the maxillary sinus exist, each with its own anatomical limitations and potential complications.

Nasal lavage with mupirocin has the potential to reduce sinonasal morbidity in endoscopic endonasal approaches for skull base surgery.

To evaluate the effects of nasal lavage with and without mupirocin after endoscopic endonasal skull base surgery.

A pilot randomised, controlled trial was conducted on 20 adult patients who had undergone endoscopic endonasal approaches for skull base lesions. These patients were randomly assigned to cohorts using nasal lavages with mupirocin or without mupirocin. Patients were assessed in the out-patient clinic, one week and one month after surgery, using the 22-item Sino-Nasal Outcome Test questionnaire and nasal endoscopy.

Patients in the mupirocin nasal lavage group had lower nasal endoscopy scores post-operatively, and a statistically significant larger difference in nasal endoscopy scores at one month compared to one week. The mupirocin nasal lavage group also showed better Sino-Nasal Outcome Test scores at one month compared to the group without mupirocin.

Nasal lavage with mupirocin seems to yield better outcomes regarding patients’ symptoms and endoscopic findings.

Infratemporal fossa schwannomas are benign, encapsulated tumours of the trigeminal nerve limited to the infratemporal fossa. Because of the complications and significant morbidity associated with traditional surgical approaches to the infratemporal fossa, which include facial nerve dysfunction, hearing loss, dental malocclusion and cosmetic problems, less invasive alternatives have been sought.

This paper reports two cases of infratemporal fossa schwannomas treated in 2012 using mini-invasive approaches. The literature regarding different infratemporal fossa approaches was reviewed.

The first schwannoma was 30 mm in size and was removed completely by a preauricular subtemporal approach. The second one was 25 mm in size and was removed completely using a purely transnasal endoscopic approach. In both cases, there were no intra-operative or post-operative complications.

These two approaches allow non-invasive and wide exposure of the infratemporal fossa as compared to classical approaches. Surgical approach should be selected according to the tumour's anatomical location with respect to the maxillary sinus posterior wall. The preauricular subtemporal approach is recommended for tumours localised posterolaterally with respect to the maxillary sinus posterior wall. Medial and anterior tumours near the maxillary sinus posterior wall can be best removed using a transnasal endoscopic approach.
