ABSTRACT

Scalp reconstruction aims to achieve an appropriate appearance and is fundamentally important to the integrity of the skeletal structure to protect the central nervous system. The present work describes the case of a child aged 1 year and 5 months with a total-thickness lesion of the scalp presenting with ischemic areas in the cranial calotte and absence of periosteum after infection. The lesion was urgently debrided, washed with 9% normal saline, and dressed with silver sulfadiazine ointment for 2 days. The patient was subsequently transferred to the surgical center, and multiple perforations were made in the outer table of the skull. A dressing was made with rayon gauze soaked with petrolatum emulsion and removed 7 days after the surgery accompanied by antibiotic administration. Finally, 10 days after surgery, split-thickness skin grafting was performed, and satisfactory aesthetic results were obtained.

INTRODUCTION

The covering of the cephalic segment is formed by specific and distinct anatomic structures. It may be divided in soft parts, represented by the scalp and its layers, and bone tissues, which consist of the cranial calotte. The soft parts are divided into 5 anatomic layers: the skin, subcutaneous tissue, galea, loose areolar tissue, and pericranial tissue.

With a purely didactic aim, lesions can be classified according to their anatomic purposes (e.g., soft and bone parts), thickness (e.g., partial and total), and time of progression (e.g., acute and late).

In total-thickness lesions of the scalp involving the loss of all the layers and exposure of the cranial calotte, covering the bone structure with vascularized tissues is critical; moreover, closing the lesion area is important for preventing alopecia1-6. The lack of covering of the cranial calotte may also lead to bone necrosis and infections of bone tissues, which may result in the loss of the cranial calotte and exposure of the central nervous system. These lesions are primarily of traumatic origin such as dog bites, burns, and neoplasia, and are rarely caused by infections.

Here, we report the case of a patient with a total-thickness lesion of the scalp of infectious origin.

 

CASE REPORT

The patient was 1 year and 5 months of age with a history of a neglected abscess in the frontal region (a home treatment was attempted); the lesion evolved to necrosis of the scalp area, and the patient was examined in the emergency unit of the Josina Machel Hospital, Luanda, Angola.

On physical examination, the patient presented with a total-thickness lesion of the scalp with ischemia in the region of the outer table of the cranial calotte, with the length being 15 cm and the width being 8 cm, irregular borders, and the presence of purulent secretion (Figure 1).

 

 

The borders of the lesion were urgently debrided, washed with 9% normal saline, and dressed with silver sulfadiazine ointment for 2 days.

The patient was subsequently transferred to the surgical center to receive multiple perforations in the outer table of the skull (Figure 2). A dressing was made with rayon gauze soaked with petrolatum emulsion and was removed 7 days after the surgery accompanied by antibiotic administration.

 

 

Finally, 10 days after surgery, granulation was observed in 96% of the lesion (Figure 3). Consequently, split-thickness skin grafting was performed (Figure 4) and satisfactory aesthetic results and good graft integrity were observed.

 

 

 

 

The patient is currently scheduled to undergo treatment of the alopecic area (Figure 5), which will be conducted with the help of a tissue expander.

 

 

DISCUSSION

In cases of extensive lesions of the scalp with loss of pericranial tissue, associated infections, or debilitated patients, or even when there is a lack of resources to conduct more elaborate procedures, the technique of micro-perforations of the outer table of the skull is the most strongly indicated.

Because children particularly present with a diploe that contains a large quantity of highly vascularized spongy bone tissue, this technique allows the formation of granulation tissue in a few days; moreover, a split-thickness skin graft can be applied over this, thus facilitating the closure of the bone area.

Although microsurgery is increasingly being recommended, the technique applied herein was developed several years earlier and remains the best option in these cases. Considering the initial infection and lesion extent, it is very important to quickly define the therapeutic plan, while taking advantage of the large amount of diploe vascularization, which is typical of patients of this age; this promotes good granulation in a few days, and allows the prompt application of a split-thickness skin graft.
