The paediatric anaesthesia mask needs to be malleable to fit against the patient's skull and also transparent so it can be visualised during the procedure. To assemble the device you connect one end of the portion of macro-drip set to the ventilation hole of the paediatric anaesthesia mask and the other end to the three-way stopcock, connecting the two syringes to the other two stopcock ports (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>).

The decision was made to treat with the MARS. Before commencing, the device was tested on five healthy adult volunteers using its maximum force. None of the volunteers reported pain during the procedure or had any complications. The risks and benefits of the procedure were explained to the families, who then signed the informed consent form and the procedure was performed at the bedside of the patients without anaesthesia (sedation was used in case 2). The patients had venous access to treat any eventualities (hypotension and seizures, for example) and were monitored by the neonatology team throughout the procedure. All three patients were placed in supine position with their head slightly rotated towards the opposite side of the fracture. The paediatric anaesthesia mask was placed over the depressed ping pong fracture, achieving a hermetic seal. Aspiration was performed slowly, first with one syringe and then with the other. The procedure was repeated and the reduction of the fracture was clear (observed through the paediatric anaesthesia mask while the procedure was being performed). The entire procedure was completed in 20 min (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>) and required a total of 240 cm<span class="elsevierStyleSup">3</span> of negative pressure in all three cases.

Zalatimo et al.<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">10</span></a> propose an alternative treatment which involves introducing percutaneous microscrews to elevate the bone. However, this type of treatment can lead to complications inherent to both the general anaesthetic (e.g. cardiovascular, respiratory and internal environment alterations, air embolism and allergic reactions, among others) and the surgical procedure (e.g. epidural, subdural and intraparenchymal haematomas, traumatic subarachnoid haemorrhage and surgical wound infection), which can prolong the hospital stay<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">6,7</span></a>.</p><p id="par0065" class="elsevierStylePara elsevierViewall">There are other treatments described in the literature involving fracture reduction systems using aspiration<a class="elsevierStyleCrossRefs" href="#bib0010"><span class="elsevierStyleSup">2,8,11–13</span></a>. This would avoid the above anaesthesia- and surgery-related complications, reducing both hospital stay and costs. Suction reduction systems are numerous and include the obstetric suction cup<a class="elsevierStyleCrossRefs" href="#bib0040"><span class="elsevierStyleSup">8,11,13</span></a> and the breast milk extractor<a class="elsevierStyleCrossRefs" href="#bib0010"><span class="elsevierStyleSup">2,12,14</span></a>, which are connected to an automatic vacuum pump. There are also reports that show complications associated with these aspiration reduction systems. Govaert et al.<a class="elsevierStyleCrossRef" href="#bib0075"><span class="elsevierStyleSup">15</span></a> reported subgaleal bleeding in neonates with vacuum-assisted delivery. Prevedel et al.<a class="elsevierStyleCrossRef" href="#bib0080"><span class="elsevierStyleSup">16</span></a> reported subdural haematomas with the use of the same device, while Musahl et al.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">17</span></a> presented a case of rupture of the superior sagittal sinus, which required surgical repair, after a delivery assisted with an obstetric vacuum cup. However, there are reduction systems with manual suction, like ours, which are not connected to an automatic vacuum pump<a class="elsevierStyleCrossRefs" href="#bib0010"><span class="elsevierStyleSup">2,3,18</span></a>. No complications beyond scalp bruising have been found with manual reduction devices. Our working team therefore decided against postoperative follow-up brain computed tomography scans on our three cases, their decision also taking into account the risk of radiation exposure and the fact that the post-procedure neurological physical examination showed no changes. Reduction devices with manual suction make it possible to see the patient's head while the procedure is being performed, and also to control the negative pressure exerted on the fracture in real time<a class="elsevierStyleCrossRefs" href="#bib0010"><span class="elsevierStyleSup">2,3,18</span></a>. Perhaps the main advantage of the MARS is that, unlike other reduction devices that use manual suction, the MARS has a three-way stopcock, allowing two 60-ml syringes to be connected in series, thereby enabling higher negative pressure to be exerted on the fracture than when using only one syringe.</p><p id="par0070" class="elsevierStylePara elsevierViewall">The ideal timing for treating a ping pong fracture after trauma is subject to debate. Compression of the brain due to the fracture could compromise brain function<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">19</span></a>.

These fractures should therefore be treated as soon as possible after the trauma. In their series of nine cases treated with a manual aspiration reduction device, Ramiro Lopez Elizalde et al.<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> describe the successful treatment of eight cases, in which the trauma was less than 74 h old. In the case with an unsuccessful outcome, the fracture was six days old. In terms of age, the younger the patient, the better the result, as there is a direct relationship between age and bone density; the younger the patient, the softer and more flexible their bones will be. De Paul Djientcheu et al.<a class="elsevierStyleCrossRef" href="#bib0055"><span class="elsevierStyleSup">11</span></a> reported the successful use of an obstetric vacuum extractor to treat a depressed fracture in a 17-year-old patient.</p><p id="par0075" class="elsevierStylePara elsevierViewall">More patients need to be successfully treated with the MARS to accurately delineate the appropriate time range for treatment after trauma, and the appropriate age range of patients who can be treated in this way.
