What is an interpolated flap?

An interpolated flap is a two-stage technique in which the base of the flap is not directly adjacent to the recipient defect. These flaps are used when insufficient tissue or mobility in nearby skin prevents the coverage of a surgical defect with primary closure or an adjacent flap.

What is the difference between interposition and interpolated flap?

Interposition flaps are similar to transposition flaps but include elevation of the incomplete skin bridge to the site of the donor defect, such as a Z-plasty. Finally, interpolated flaps move the skin paddle and pedicle over an intact skin bridge with its pedicle base removed from the defect.

What are the types of flap?

Flaps may be composed of just one type of tissue or several different types of tissue. Flaps composed of one type of tissue include skin (cutaneous), fascia, muscle, bone, and visceral (eg, colon, small intestine, omentum) flaps.

What is the CPT code for interpolated melolabial flap?

The division and inset of the interpolation flap is a billable procedure specified with CPT 15630, “Delay of flap or sectioning of flap (division and inset); at eyelids, nose ears, or lips).” However, a modifier is needed, since the procedure is done during the 90-day global period.

What is the difference between free flap and pedicle flap?

When the TRAM flap is a pedicle flap, it remains attached to its blood supply, with the tissue surgically tunneled underneath the skin to the breast region. When the TRAM flap is a free flap, the tissue is detached and cut away from its blood supply before being transferred.

Interpolation flap reconstruction of the ear following BCC excision. #82

What is the difference between random flap and axial flap?

Axial Pattern Flap-a

arterio-venous system running along its long axis. Such a flap, because of the presence of its axial arterio-venous system, is not subject to many of the restrictions which apply to flaps in general. Random Pattern Flap-a flap which lacks any significant bias in its vascular pattern.

What type of flap is a pedicle flap?

A type of surgery used to rebuild the shape of the breast after a mastectomy. Tissue, including skin, fat, and muscle, is moved from one area of the body, such as the back or abdomen, to the chest to form a new breast mound.

What is a Melolabial flap?

The melolabial flap is a versatile technique for functional and esthetic rehabilitation of defects of the central portion of the face. Variations of this flap may be used to reconstruct small- to medium-sized defects involving the chin, upper and lower lip, cheek, nose, and lower eyelid.

What is the CPT code for interpolation flap takedown?

For Stage 2 (your current operative note), CPT code 15630 is correct. Make sure you apply modifier 58 to indicate this is a staged procedure, otherwise it will be bundled into the global period for 15731.

What is Melolabial?

1 The melolabial region is made of cheek tissue surround- ing the melolabial crease from the ala to the oral commissure. Sometimes referred to as nasolabial, melolabial is an anatomically more precise description.

What are the 4 types of flaps?

What are the 4 types of flap designs?

What is the most commonly used flap?

Triangular flap is the most widely used flap design but it has many shortages such as dehiscence, alveolar osteitis, reactionary bleeding, and periodontal disruption distal of second molar.

What interpolated means?

What is the meaning of the word interpolation?

Interpolation Meaning

In short, interpolation is a process of determining the unknown values that lie in between the known data points. It is mostly used to predict the unknown values for any geographical related data points such as noise level, rainfall, elevation, and so on.

What type of flap is nasolabial flap?

The nasolabial flap is an axial flap but may be utilized as a random flap [4]. The flap receives its blood supply from the angular artery (a branch of the facial artery), the infraorbital artery, and the transverse facial artery [6].

What is a Mustarde flap?

Mustardé/Tenzel Flap

The Mustardé flap is used for defects of the lower eyelid and cheek. [8] This flap distributes tension in a horizontal plane and is used to prevent excessive tension on the lower eyelid and subsequent ectropion.

What is an ent free flap?

Free flap surgery, also called free tissue transfer, is a reconstructive surgery technique that involves the transfer of skin from one area of the body to another. The tissue that's being transferred is still linked to a major vein or artery. The transferred tissue is attached to an injured area via a graft or flap.

What is U1 and U2 modifier?

Modifier Description

U1. Medically necessary delivery prior to 39 weeks of gestation. U2. Delivery at 39 weeks of gestation or later.

What is the difference between nasolabial and melolabial flap?

They separate the cheeks from the upper lip. The term derives from Latin nasus for "nose" and labium for "lip". Nasolabial fold is a misnomer, however. The proper anatomical term is melolabial fold, meaning the fold between the cheek and lip.

What is a glabellar flap?

The glabellar flap is a V-Y flap that allows the skin to be transposed from the glabellar area by advancing and rotating toward the defect.

What is a Tripier flap?

The Tripier flap is a transposition flap utilizing redundant tissue on the upper eyelid to repair defects of the lateral inferior eyelid. The authors describe Their technique for the single-pedicle Tripier flap, which does not rely on the inclusion of orbicularis muscle or innervation.

What is the difference between a tram flap and DIEP flap?

TRAM flap focuses on using tissue from your abdominal muscles, as well as some soft tissue. DIEP flap spares the abdominal muscle and uses only soft fat tissue and local blood vessels. Each procedure has long recovery times, and similar side effects.

What is the most common pedicle based flap used for breast reconstruction?

The most common pedicle flap used for breast reconstruction is the latissimus dorsi (LD) flap, where tissue from the back (skin, fat, and muscle) is used to make a new breast. Tissue from the abdominal wall (tummy) can also be used as a pedicle flap (transverse rectus abdominis muscle or TRAM flap).

Why is it called the pedicle?

The word "pedicel" is derived from the Latin pediculus, meaning "little foot". The stem or branch from the main stem of the inflorescence that holds a group of pedicels is called a peduncle. A pedicel may be associated with a bract or bracts.
