Reconstruction Flashcards
The mathes and Nahai Classification system is for what type of flaps?
The classification of muscle flaps
Type 1-Type 5
Type 1 One vascular pedicle (tensor fascia lata
Type 5 One dominant vascular pedicle and secondary segmental vascular pedicles (pectoralis major and latissumus dorsi)
What is the angiosome theory?
Angiosome theory proposes that the human body is composed of 40 blocks of composite tissue
What limits the regional soft tissue flap?
The arc of rotation and the limited volume of soft tissue available
The submental artery cross (anteriorly/posteriorly )along the mylohyoid muscle and arises (behind/in front of) the submandibular gland
Arises behind the submandibular gland and cross the mylohyoid muscle anteriorly
Does the submental artery usually pass deep the anterior belly of the diagstric?
Yes, 70% of the time, the submental artery passes deep to the anterior belly of the diagstric
List some applications for the utilization of the submental island flap?
The submental island flao is useful for the tongue, floor of mouth, and buccal mucosa defects
What artery is the temporalis muscle flap based on?
What Mathes and Nahai muscle classification is the Temporalis Flap?
The deep temporal arteries and type 2 muscle with one dominant pedicle plus minor pedicles
What is the second blood supply of the temporalis flap and what is this a branch of?
The second blood supply of the temporalis flap is the middle temporal artery, which is a branch of the superficial temporal artery
What is the deep temporal artery a branch of?
The deep temporal artery is a branch of the internal maxillary artery
What is the origin and insertion of the temporalis muscle?
The superior temporal line and the coronoid process are the origin and insertion points of the temporalis muscle
Approximately, how far superior to the zygomatic arch does the temporalis fascia splint into a superficial and deep layer
Approx. 2cm superior to the zygomatic arch
Where can the temporalis flap be utilized?
The temporalis flap can be utilized for relining defects of the maxilla, ipsilateral hard and soft palate, pharynx, retromolar trigone, and buccal mucosa
What are the origins and insertion point of the pectoralis major muscle?
Origins of the pectoralis major include the sternum, clavicle, and external oblique aponeurosis and the muscle inserts on the greater tubercle of the humerus.
What muscle compensates for the loss of the pectoralis major when this muscle is used for a flap?
The latissimus dorsi muscle compensates for the pectoralis muscle
According to Mathes and Nahai, what Type of muscle flap is the pectoralis muscle flap?
Type 5, with one dominant branch, the pectoral branch of the thoracoacromial artery and secondary segmental branches through the internal mammary artery
