| Introduction|| |
Cranioplasty is a reconstructive surgery consisting of repair of skull bones and the dura mater defects, caused by trauma or surgery.
Protakril implants, being the most commonly used materials, have several advantages. They are easy to model and have a relatively low cost. However, they cause a greater risk of complications during the postoperative period. Toxic and allergenic effects of the mixture components may cause local inflammatory reactions. The use of titanium implants is the most preferable due to their high biocompatibility, high mechanical strength, and low specific weight. Titanium has no toxic effect on the tissues while achieving direct contact with the bone. In addition, due to the low risk of development of pyo-inflammatory complications, titanium implants can be used in craniofacial lesions with the paranasal sinuses involvement.,, Despite the constant development of new techniques and materials to eliminate defects in the skull, the cranioplasty issue remains relevant. Often, simultaneously with cranioplasty, it is necessary to resolve the question of skin integument and the dura matter. The reconstruction of the skin integument is often solved by resection of scar tissue, relocation, and rotation of the skin integument flap and for dealing with extensive scar surfaces, a preliminary extension of the skin integument by subcutaneous implantation of expanders and plastic-free splitting skin integument flap is required. With extensive soft-tissue defects, the method of “walking flap” or “Filatov stalk” was often used. Nevertheless, taking into consideration several complications caused by this technique, its duration, as well as the modern development of microsurgical technologies (prefabrication of flaps, transplantation, and transposition of tissue complexes), the described technique has ceased to apply in clinical practice.
| Case Report|| |
The article describes a clinical case of the reconstruction of the skin integument, skull bones, and dura mater postoperative defect in a patient. The patient was admitted to the hospital on an emergency basis. The hemorrhagic stroke in the form of subarachnoid hemorrhage caused by the rupture of the superior mesenteric artery (SMA) saccular aneurysm (Hunt and Hess Grade II, Fisher Grade III) was diagnosed. The patient was conscious, focused, sociable, without any focal signs, but he had moderate cerebral and meningeal symptoms. The patient underwent an emergency craniotomy for SMA aneurysm clipping under a microscope.
In the postoperative period, the patient had a complication. A massive right-hemispheric ischemic stroke developed against the background of the surgical intervention and the postoperative vasospasm, the patient had the symptomatic of the dislocation syndrome, oppression of consciousness to coma I.
The urgent decompression surgery with extended cranial vault resection in the right frontotemporal part with the reconstruction of the dura mater was performed. Following surgical site infection, repeated surgical inspections, and necrectomy of the wound edges resulted in an extensive defect of the skin and cranial vault bones as well as in the dura mater defect in the right frontotemporal part [Figure 1].

To close the defect of the surgical wound, it was decided to resect the open area of the skull bone and to perform the autoplasty with free split-thickness graft taken from the hip. At the first stage, the resection of nonviable bone was performed [Figure 2] and [Figure 3].

At the second stage, autodermoplasty was performed with a free split flap thickness of 0.4 cm from the front surface of the right thigh [Figure 4] and [Figure 5].
On the pictures presented above, autografts have successfully healed, both on the dura mater and on the free brain tissue. The absence of liquorrhea is explained by the fusion of the skin integument along the defect edges and by the limitation of the subarachnoid space.
The patient was discharged for further rehabilitation treatment after his condition stabilized.
| Discussion|| |
The plastic of the dura mater is performed by using autotransplantation (periosteum and aponeurotic flaps), allografts and xenografts (synthetic membranes).
For surgery performed on the brain and bones of the skull in everyday clinical practice, the most common complications are bleeding with the formation of hematomas, surgical wound infection, necrosis of the skin integument edges of the wound, osteomyelitis, and sepsis. Each of these complications can occur either relatively typically or follow untypical scenario.
Hence, extensive defects of the skin integument and bones of the skull are formed after local infectious processes and necrectomy. The absence of a skin integument barrier in turn forms an open wound with the exposure of both the bones of the skull, the dura matter, and brain tissue. It is difficult to decide how to close the extensive skin integument defects in the absence of the underlying bone flap and the dura matter. In this case, the open wound becomes an additional source of infection and the ongoing liquorrhea. The skull defect can be freely replaced with an artificial graft, but the extensive defect of the skin integument is not so easy to close due to the rigidity and low mobility of the skin epicranial aponeurosis.,
| Conclusion|| |
The best way to close combined defects of the skull bones and the soft tissue is to use allograft (mesh nikelid-titan plates) and to perform the autodermoplasty with split flaps as well as to apply modern techniques of balloon dilatatie, prefabrication of flaps with their subsequent transposition or transplantation.,, When curating patients with a severe form of disease in neurosurgical departments, it is necessary to take into account the fact that time does not play in favor of the patient. It is necessary to make a clear, balanced decision, not delayed in time, as well as to assess the severity of patient who will not be able to tolerate complex reconstructive surgeries simultaneously, so it is necessary to stabilize the patient and perform the first stage which is the “simplest” reconstructive surgery to close a large defect. For this stage, the most suitable is autodermoplasty with split flaps. Later, after the patient's condition is stabilized and infectious processes are stopped, it is recommended to carry out a number of reconstructive surgeries to close defects of the skull bones and soft tissues.
