What is a coronal flap?
The coronal approach is placed remotely in order to avoid visible facial scars. 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).
What is a coronal incision?
The coronal or bi-temporal approach is used to expose the anterior cranial vault, the forehead, and the upper and middle regions of the facial skeleton. The extent and position of the incision, as well as the layer of dissection, depends on the particular surgical procedure and the anatomic area of interest.
Where is the coronal scalp?
Prior descriptions of the coronal scalp flap include an incision just behind the hairline with the lateral components of the approach created in the pre-auricular areas: the hairline of the patient being a primary consideration in the placement of the incision for the flap.
What is a Pericranial flap?
The anterior-based pericranial flap is very versatile and can be used in sealing of the nasal cavity in frontal sinus reconstruction, for closure, or obliteration of skull base defects, etc. The pericranial flap can also be extended to fill small volume defects.
What is Gillies approach?
Temporal (Gillies) approach – Skin incision The Gillies technique describes a temporal incision (2 cm in length), made 2.5 cm superior and anterior to the helix, within the hairline. A temporal incision is made. Care is taken to avoid the superficial temporal artery.
What is a Cranialization?
Introduction. Severe injuries which result in disruption of greater than 25% of the posterior table should be considered for cranialization. This involves exposure of the entire sinus, meticulous removal of all sinus mucosa, and removal of the posterior table bone.
What is the coronal structure?
The coronal suture is a dense and fibrous association of connection tissue located in between the frontal and parietal bones of the skull. At birth, the sutures decrease in size (molding) and allow the skull to become smaller. In children, the suture enables the skull to expand with the rapidly growing brain.
What does Pericranial mean?
: the external periosteum of the skull.
What is Gillies temporal approach?
What is Zygomaticomaxillary complex?
The zygomaticomaxillary complex (ZMC) plays a key role in the structure, function, and aesthetic appearance of the facial skeleton. It provides normal cheek contour and separates the orbital contents from the temporal fossa and the maxillary sinus.
What is frontal sinus Cranialization?
Severe injuries which result in disruption of greater than 25% of the posterior table should be considered for cranialization. This involves exposure of the entire sinus, meticulous removal of all sinus mucosa, and removal of the posterior table bone.
What are coronal suture bones?
The coronal suture is a dense, fibrous connective tissue joint that separates the two parietal bones from the frontal bone of the skull.
