The blood supply to a pedicled transverse rectus abdominis myocutaneous (TRAM) flap is based on which vessels?
Answer: Superior epigastric vessels
The pedicled TRAM flap is based on the superior epigastric vessels, which are the terminal continuation of the internal mammary artery.
Which anatomical structure passes through the carpal tunnel along with the nine flexor tendons?
Answer: Median nerve
The median nerve passes through the carpal tunnel along with the four tendons of flexor digitorum superficialis and four of flexor digitorum profundus and the flexor pollicis longus.
A Z-plasty with limbs at 60-degree angles theoretically increases the length of the central limb by approximately:
Answer: 75%
A 60-degree Z-plasty provides approximately 75% lengthening of the central limb and is the most commonly used angle in clinical practice.
During parotidectomy, the facial nerve is most reliably identified at which landmark?
Answer: Tragal pointer (tragal cartilage pointer)
The tragal pointer is a reliable landmark where the main trunk of the facial nerve lies approximately 1 cm deep and inferior to the tip of the tragal cartilage.
In hand surgery, the Camper chiasm refers to the anatomical arrangement of which tendons at the level of the proximal phalanx?
Answer: Flexor digitorum superficialis splitting to allow passage of flexor digitorum profundus
Camper's chiasm is the decussation where the flexor digitorum superficialis splits into two slips around the FDP tendon at the level of the proximal phalanx.
The superior gluteal artery perforator (SGAP) flap is particularly advantageous over the DIEP flap in which patient population?
Answer: Thin patients with insufficient abdominal tissue
The SGAP flap is preferred in thin patients who lack sufficient abdominal tissue for a DIEP flap, as the gluteal region provides an alternative fat source.
What is the primary advantage of a keystone island perforator flap over a standard random-pattern advancement flap?
Answer: Named perforators provide reliable axial blood supply allowing larger flap dimensions
The keystone flap is designed around named perforators, providing an axial blood supply that allows larger flap dimensions compared to random-pattern flaps limited by length-to-width ratios.
