The bicoronal flap was first described by Hartley and Kenyon (neurosurgeons) to gain access to the anterior cranium in 1907. It extension as an access flap to the upper and lateral aspect of the face was pioneered by Tessier (1971). Esthetically, it is pleasing as the surgical scar is hidden within the hair.
Where is a coronal incision?
The traditional coronal incision starts at the root of the helix and is carried coronally to the vertex of the skull and then to the contralateral helical root. The incision can be extended inferiorly as a preauricular incision to the level of the tragus or beyond for further exposure.
What is an osteoplastic flap?
Background The osteoplastic flap provides access to pathology of the frontal sinus and is often performed with obliteration, which can result in significant long-term complications. Objective To describe the authors’ approach to osteoplastic flap without obliteration.
What is a Pericranial flap?
It is currently deployed via a bifrontal craniotomy and is placed primarily as a support beneath the frontal lobes. The pericranial flap may also be used to repair dural laceration and defects. The sinonasal surface is routinely grafted with split-thickness skin or dermis.
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 transverse incision?
A transverse incision 6cm above the pubic tubercle is made through the rectus abdominis to gain access to pelvic structures. The incision is made through the rectus abdominis on both sides, through the linea alba, and the medial aspects of the obliques.
Where is the temporal nerve located?
The frontal (or temporal) branch of the facial nerve is a motor nerve that innervates the frontalis and portions of the orbicularis oculi, corrugator supercilii, and procerus muscles. It traverses the superficial fat pad above the superficial temporal fascia toward the lateral brow.
What is a total Ethmoidectomy?
A complete ethmoidectomy is the removal of the anterior and posterior ethmoid air cells. ▪ A complete ethmoidectomy follows a maxillary antrostomy and is one component of complete functional endoscopic sinus surgery.
What is frontal sinusotomy?
What is endoscopic frontal sinusotomy? Endoscopic frontal sinusotomy involves the use of telescopes and cameras through the nose to reach the anterior ethmoid sinus, and then the frontal sinus above. These areas are opened and disease is removed.
What is frontal sinus obliteration?
Osteoplastic frontal-sinus obliteration is a surgery that eliminates the frontal sinuses in order to prevent chronic infection, or in response to head trauma or cancer. Patients needing this surgery often have undergone other less-invasive procedures such as endoscopic sinus surgery.
What does Pericranial mean?
per·i·cra·ni·um (pĕr′ĭ-krā′nē-əm) pl. per·i·cra·ni·a (-nē-ə) The external periosteum that covers the outer surface of the skull. [New Latin pericrānium, from Greek perikrānion, from neuter of perikrānios, around the skull : peri-, peri- + krānion, cranium; see cranium.]
What is a Gillies lift?
The Gillies approach involves a temporal hairline incision, placing an elevator superficial to the surface of the temporalis muscle under the deep temporal fascia and sliding the elevator under the arch to lift it into reduction.
What is Zygomaticomaxillary complex?
The zygomaticomaxillary complex (ZMC) is a major buttress of the midfacial skeleton. The ZMC is important to structural, functional, and aesthetic appearances of the facial skeleton. A ZMC fracture is also known as a tripod, tetrapod, or quadripod fracture, trimalar fracture or malar fracture [1,2].
What are zygomatic bones?
zygomatic bone, also called cheekbone, or malar bone, diamond-shaped bone below and lateral to the orbit, or eye socket, at the widest part of the cheek. It adjoins the frontal bone at the outer edge of the orbit and the sphenoid and maxilla within the orbit.
When is a transverse incision used?
Purpose: Both midline and transverse abdominal incisions are used for exposing the infrarenal aorta. Transverse incisions are said to cause less pulmonary and systemic complications, but the claimed advantages may be because most transverse incisions are extraperitoneal, whereas midline incisions are intraperitoneal.
How many layers are stitched during C-section?
How Many Layers Are Cut During A Cesarean Section? There are 5 layers that we need to get through before we can get to your uterus. Once the peritoneum is entered, the uterus should be accessible. Of these 5 layers, the rectus muscle is the only layer that isn’t cut.
Does C-section scar go away?
C-section scars do not go away completely. They can fade on their own with time or with treatments, but a visible line is often left. If a C-section scar bothers you because of cosmetic issues, here are a few ways that can lessen its appearance.
What does the temporal nerve affect?
The temporal branch is the superior branch of the facial nerve. The nerve provides motor innervation to the frontalis muscle, corrugators, procerus and occasionally portions of the orbicularis oculi. Injury to this nerve during dissection will lead to brow asymmetry and brow ptosis and should be avoided at all cost.
What does the temporal nerve control?
It emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue. The nerves typically travels from the pons through the facial canal in the temporal bone and exits the skull at the stylomastoid foramen.
Where does deep temporal nerve come from?
Structure. The deep temporal nerves are usually two in number and termed the anterior deep temporal nerve and posterior deep temporal nerve. They branch from the anterior division of the mandibular nerve and travel above the upper border of the lateral pterygoid muscle.
Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
