2016年1月22日 · The subgaleal connective tissue is a largely avascular, filmy layer of loose fibroareolar tissue interposed between the galea aponeurotica superficially and the pericranium deeply. Anteriorly, the subgaleal layer extends deep to the frontalis and orbicularis oculi muscles.

The subperiosteal or subgaleal planes are commonly used for coronal flap dissection. The scalp incision is extended lateroinferiorly into the preauricular region to gain access to the zygomatic arch and/or temporomandibular joint (TMJ).

A indicates scalp (subgaleal plane/sub-SMAS plane); B, temporal region (supra-SMAS plane); C, forehead (sub-SMAS plane or subcutaneous plane); D, periorbital region (preseptal or preorbital...

2024年5月5日 · This allows the subaponeurotic/subgaleal space to extend anteriorly beneath the orbicularis oculi into the eyelids, yielding an effective dissection plane. As outlined earlier, this plane allows anterior and inferior movement of surgical blood, leading to …

2011年1月1日 · We now describe the characteristics of the different planes of the head and neck (Figure 3). Scalp (Figure 3A) The appropriate plane is the subgaleal plane. Dissection along this avascular plane will avoid excessive bleeding and damage to the terminal hair follicles.

They form an extensive net of anastomoses that run superficial to the galea in the subcutaneous tissue, making the subgaleal plane ideal for undermining in a relatively bloodless field. The galeal aponeurosis is contiguous with the paired frontalis muscles anteriorly, the paired occipitalis muscles posteriorly and the temporoparietal fascia ...

Therefore, many researchers advise against dissection in the plane between the galea aponeurotica and the temporal fascia, known as suprafascial (subgaleal) dissection.

2019年3月3日 · The skin is tethered to the underlying subcutaneous connective tissue and galea by muscle and fibrous bands. Local flaps commonly incorporate the outer three layers of the scalp, and flap undermining is easily performed through the subgaleal space, a relatively avascular plane.

2009年12月1日 · The subgaleal layer, or space, is the loose areolar tissue between the galea aponeurotica and the pericranium. Anteriorly, this extends to the upper eyelids because of the lack of bony insertion, therefore allowing collections to pass from the scalp to the upper eyelids.

Craniofacial reconstruction often involves the use of dissection in the subperiosteal or subgaleal plane to access the cranial vault and facial skeleton. Clinically, physical changes to the periosteal layer and underlying cortex were observed in the re-operative field.
