ABSTRACT

T

Reconstruction of the scalp following oncologic resection is a challenging undertaking

RI P

owing to the variable elasticity of the soft tissue overlying the calvarium and the limited amount of tissue available for recruitment. Defect size, location, and skin characteristics

SC

heavily influence the reconstructive options available to the surgeon. Reconstruction

NU

options for scalp defects range from simple direct closure, to skin grafting, to adjacent tissue transfer with local flaps, and ultimately to free tissue transfer. Dermal regeneration

MA

templates have also gained popularity in the recent past. Often times a primary closure with multiple local flaps can be a prime choice in these scenarios. One such modality of

ED

multi-flap closure, the Orticochea flap, is an excellent option for scalp reconstruction as it

PT

decreases operative time, may provide hair-bearing skin, and potentially avoids the risks of general anesthesia in debilitated patients. We present an interesting case of a patient with a

CE

large scalp defect following melanoma excision that was successfully reconstructed with an

AC

Orticochea flap. A review of scalp reconstruction and uses of the Orticochea flap will follow the case presentation.

CASE PRESENTATION A 61-year old Caucasian gentleman presented to the office with a two year history of a slowly enlarging hyperpigmented lesion of the occipital scalp. The patient reported a history of significant sun exposure. Examination of the scalp revealed a 2.5 cm ulcerated hyperpigmented lesion of the occipital scalp, along with a 1 cm focus of hyperpigmentation anteriorly and a smaller focus of irregular hyperpigmentation posteriorly. The remainder

was unremarkable.

RI P

A punch biopsy of the lesion was performed, revealing malignant melanoma with depth of invasion of at least 0.9 mm, and mitotic index of 1/mm2, providing a preliminary tumor

SC

stage of at least T1b. A chest roentgenogram was negative, and a PET/CT was positive only

NU

for uptake at the primary site.

MA

Options were reviewed with the patient, and the patient elected to proceed with wide local excision of the primary lesion along with a sentinel lymph node biopsy. The patient was

ED

taken to the operating room, and sentinel node biopsy was negative for metastatic spread.

PT

Following excision of the primary cancer, there was an approximately 100 cm2 cutaneous

CE

defect down to the calvarium (FIGURE 1). In order to repair the defect, an Orticochea flap was employed for closure (FIGURE 2). The patient required galeotomies and extensive

AC

back-cuts given the tightness of the scalp; however, once the flaps were advanced, skin grafting was not necessary as primary closure could be achieved utilizing mechanical creep.

During the post-operative follow up period, the patient did well without any evidence of complication including wound breakdown, recurrence, or flap necrosis. FIGURE 3 shows a photograph of the patient’s well healed scalp at five months following surgery.

DISCUSSION

T

Scalp defects present in a variety of sizes, locations, and depths, making their

RI P

reconstruction a regular topic for analysis within the reconstructive literature. Managing

SC

these variables alone can make the reconstructive effort challenging. The addition of unique anatomy and complex defects morphs the original reconstructive ladder into a fluid

NU

puzzle filled with subtle iterations1. Within the early years of scalp reconstruction, the primary focus was healthy tissue coverage – similar to other areas of the body. In the

MA

modern era of operative advancements, the focus has shifted to a functional and

ED

aesthetically sound reconstruction2. This optimized paradigm centers around maintenance of hairlines and hair growth patterns, in addition to maintaining normal tissue thickness –

PT

making scalp reconstruction distinct from other regions in the human body. Furthermore,

CE

multiple scalp layers create a strong yet extremely inelastic reconstructive canvas, making

AC

the critical goal of closure without tension even more important3.

The challenge posed to the reconstructive surgeon can be summarized by three idioms- 1) variety of defects and origins, 2) hair line and growth aesthetics, and 3) unique and inelastic native anatomy. Taking the above into account, we approach a scalp defect starting with the natural steps of the reconstructive ladder. Simple direct primary closure is usually limited to small defects <3cm, that can be closed with minimal involvement of natural hair lines. If needed, galeal scoring and undermining can be used to ensure a tension free direct primary closure4. Secondary intention healing or skin grafting may also be viable options for smaller defects, utilizing healthy periosteum, or when indicated,

ACCEPTED MANUSCRIPT accessing the diploic bone layer to promote granulation and allow for skin grafting at a second stage. However, the disadvantage of these procedures is that the reconstruction is

T

not hair bearing, and often the native tissue thickness is not reproduced, resulting in

RI P

contour irregularities. In this particular scenario, dermal regeneration templates can be useful adjuncts to enhance granulation and tissue thickness. Local advancement flaps are

SC

the superior option, especially when the defect lies within the area of the scalp amenable

NU

to extensive undermining4. These flaps can range from the commonly used O-Z or pinwheel flaps, to our focus within this case, the Orticochea flap, sometimes called the “banana-peel’

MA

flap5. Basing these flaps on a reliable vascular pedicle allows for transfer of significantly larger areas of tissue, and closure of larger defects3. Both local and regional pedicled flaps

ED

are possible (Juri, supraclavicular, trapezius, etc.). Tissue expansion has become a common

PT

and popular technique, allowing hair bearing native scalp to be stretched and then reset on

CE

a defect, however serial expansion of the implant is typically required postoperatively, and therefore immediate reconstruction may not be possible. Finally, if complete coverage and

AC

tension free closure cannot be attained through regional or local advancements, free tissue transfer is the next viable option. The most commonly described include the latissimus dorsi and anterolateral thigh free flaps6. Hair transplantation is a useful adjunct to restore the hairline after reconstruction (reference?), although hair styling and wigs may also suffice.

The Orticochea flap, first described by creator Miguel Orticochea in 1967 and then revisited and altered in 1971, is a local advancement and rotation flap comprised of three mobile segments. The fundamentals of this flap rely on a thorough understanding of the vascular

ACCEPTED MANUSCRIPT territories of the scalp, and how to maintain perfusion to the three flaps. Often times, galeotomies can allow for adequate expansion and coverage. The Orticochea technique has

T

specific qualities that make it a versatile and useful flap. It allows for coverage of a large

RI P

defect, repairs like with like, and allows for manipulation of hair lines & borders7,8. When utilizing the Orticochea flap, the surgeon must recognize that in an attempt to further

SC

expand each flap, the undermined galeal layer can be perpendicularly scored to allow for

NU

greater elasticity. Care must be taken when creating these perpendicular galeotomies not to de-vascularize the rotated flap by injuring the underlying vascular pedicle9. It is also

MA

important to keep the tips of the individually raised flaps to approximately 90 degrees to prevent risk of vascular compromise as well. The scalp is divided into vascular territories

ED

and when initial flaps are opened and undermined, each should include one of the

CE

PT

following arterial sources: temporal, occipital, or supraorbital/supratrochlear5.

Once the three flaps have coalesced to cover the initial defect, if a residual defect exists

AC

from the donor site, it can either be closed with local tissue or a skin graft. If a skin graft is necessary, the donor defect is designed in such a fashion that it lies in the posterior scalp where it is less visible, and care is taken to preserve the periosteum to encourage take of the graft. The use of intraoperative tissue expansion has been mentioned in the literature as a successful way to lengthen flaps. Ultimately, the size of a defect proportionally determines the size of the flaps (larger defects require larger flaps), while the laxity of the surrounding scalp is inversely proportional to the size of the flaps (a tight scalp will require a larger back cut to allow for adequate coverage).

ACCEPTED MANUSCRIPT Frodel et al categorized two distinct groups that benefit from the Orticochea flap- 1) severely debilitated patients who cannot tolerate extended anesthesia, and 2) patients who

T

prefer primary reconstruction with hair-bearing scalp skin3. Patients who are unable to

RI P

tolerate general anesthesia or have significant medical limitations to extended operative times can be suitable candidates to have the procedure done entirely under local

SC

anesthesia. FIGURES 4,5 and 6 show intraoperative photographs of a patient with a scalp

NU

defected reconstructed with the Orticochea flap under local anesthesia by the senior author (M.A.). With the scalp reconstructive algorithm introduced by Desai et al, the Orticochea

MA

flap plays the best role when there is a large(>30cm2) frontal or vertex defect, no history of radiation, and no hairline distortion5. Utilizing another algorithm approach coined by

ED

Leedy et al, the Orticochea flap has a role within occipital and anterior defects, specifically

PT

those in which the defect cannot be closed primarily without distortion of the respective

CE

hairlines6.

AC

Although there have not been large-scale studies on the Orticochea flap in recent literature, it remains a viable option in the scalp reconstructive ladder. There have also been more recent mentions of the Orticochea methodology applied to the treatment of velopharyngeal incompetence (VPI)10. Wojcicki et all have demonstrated with larger patient sets that the Orticochea technique can be used as an effective options in special populations with VPI such as cleft palate patients.11.

With the advent of free tissue transfer and dermal regeneration templates, the Orticochea flap and similar advancement flaps have become less popular for large scalp defects. Our

ACCEPTED MANUSCRIPT case demonstrates its use as an effective alternative, and should be kept in the armamentarium of the reconstructive surgeon, as superior results can be achieved without
