Because of its elevation and rotation it is effectively physiologically delayed, augmenting its blood supply. 21.10). The inset was completed.

It avoids complex intranasal manipulation and minimizes the risk of postoperative bleeding or nasal obstruction, associated with other techniques. Potential clotting problems or easy bruising indicates a potential surgical risk. The skin paddle can be positioned in the precise center of the forehead. Accessed: Apr 10, 2019. Possible flap induration and loss of pliability. The adjacent defect within the upper lip had been resurfaced with bilateral nasolabial flaps. This site needs JavaScript to work properly. eCollection 2020 Apr. Following rotation into the defect, the apex is placed at the lateral edge and the point at the inferior tip. Forehead Skin Flaps J. S. P. WILSON N. M. BREACH EDITORIAL COMMENT Historically, the forehead flap is one of the first axial flaps described, and it achieved enormous importance in head and neck reconstruction. If necessary, they can be performed under light monitored sedation or local anesthesia alone.
This maintains the skin vascularity through the deep dermis, frontalis muscle and axial supratrochlear vessels. Excess forehead skin is trimmed and the forehead skin inset with percutaneous quilting sutures and a single layer skin closure. A revision may be performed to further refine the alar crease, if needed. If the flap is designed with a proximal taper, it may be possible to pull the flap inferiorly and redrape the tissue more effectively. 2018 May. Nasal defects may occur from a variety of etiologies, the most common being related to cutaneous malignancies and their excision.

Consider surgical delay of a forehead flap when: A significant old scar, which may interfere with its axial vessels, lies within the proposed flap territory. The vascularity of a full-thickness flap is illustrated by the safety of such complex skin extensions. 2020 Apr 24;8(4):e2713.
The forehead donor site can be washed within 24 h. Routine showering is permitted within 24 hours of all surgical sites. Almost all major nasal reconstruction will require a revision procedure four months after the initial reconstruction to improve the final result.

A full-thickness 12 mm lining defect was present within the apex of the left vestibule. Nasal reconstruction poses the challenges of restoring aesthetics in a prominent area on the face while preserving function. The skin is then lifted with the underlying fat and some muscle, but kept attached at the eyebrow. It should be incised along its borders, but not elevated, during the preliminary operation to improve its blood supply. The pedicle may be based on either side, allowing choices between flap length and the arc of pedicle rotation. Underlying excess soft tissue is excised to reveal soft vascular vestibular lining. The STA lies superficial to the epicranial aponeurosis and thus is easily identified when the flap is raised on its narrow pedicle.

After the first stage of the forehead flap transfer, the forehead donor site is healing spontaneously.

Additional onlay grafts are added to create further dorsal height and shape. The risks of failure also increase if the flap gets cold, or if you smoke. ( B ) 2-weeks…. A forehead flap should be designed as a tailored garment which covers the nose without excess or deficiency. The past repair had not met the demands of the defect, anatomically or aesthetically. Clipboard, Search History, and several other advanced features are temporarily unavailable. Forehead flaps are highly vascular. The forehead flap was transposed to the defect. The flap remains soft and non-contracted, even if the skin graft fails to take and requires reapplication. The skin of the proximal pedicle is trimmed, returning the medial eyebrow to its normal position and inset as a small inverted V whose scars simulate the normal frown crease. The editors caution the surgeon to have all preliminary reconstructions completed, so that the only defect left to reconstruct is the nose itself. Dominique Dorion, MD, MSc, FRCSC, FACS is a member of the following medical societies: Canadian Society of Otolaryngology-Head & Neck SurgeryDisclosure: Nothing to disclose. It passes superficial to the corrugator muscle and deep to the orbicularis, ascending in a paramedian position for approximately 2 cm before piercing the frontalis muscle as seen in the image below. The precise anatomic anastomosis between the named major vessels in the medial brow region varies. One month later, they were hinged down to supply proximal lining.

Over the next 3-4 weeks the flap ‘learns to live’ from the nose, and new blood vessels from the nose grow into the flap skin. The defect of the nasal floor has been replaced. Primary cartilage batten grafts were positioned to support the alae. The template is positioned on the forehead donor site over the territory of the planned pedicle and marked with ink. In the first, partial necrosis of one ala followed transfer of a pre-expanded, second forehead flap, used to reconstruct a cocaine nose. The supratrochlear artery exits at the superior and medial corner of the bony orbit, approximately at the medial point of the eyebrow. Patient expectations are a significant consideration. The entire ala subunit was resurfaced with a full-thickness forehead flap. The outline and the dimension of the flap will be designed to resurface parts or all of the dorsum, tip, and ala depending on the defect. Four weeks later (7–8 weeks after forehead flap transfer), the pedicle is divided. The inferior part of the forehead scar through the medial eyebrow is reopened. The site of pedicle division is marked, leaving excess tissue that can be trimmed at the time of fine tuning the reconstructed subunit. The alar creases may be refined by direct incisions in the future, if the patient wishes. The median forehead flap is harvested from the mid forehead and has a wide pedicle based in the center of the forehead, which originally captured both supratrochlear vessels as seen in the image below. Lateral temple skin was elevated, based on the superficial temporal vessels. However, distal lining was absent along both nostril margins. A small sponge bolus was placed within the nostril for 5 days. 2014 Sep 9. Photograph on left depicts a nasal defect following Mohs surgery. Residual skin of the ala will be discarded to permit subunit skin resurfacing of the entire alar subunit. The subunits are marked with ink. The primary cartilage grafts are well integrated into the repair. In this operation a reconstructive surgeon uses skin from the forehead above the eyebrow and pivots it vertically to replace missing nasal tissue. The residual ala was sutured to the advancement flap. Skin of the dorsum, tip, and soft triangles was missing.

The blanching caused by epinephrine will make intraoperative evaluation of tissue vascularity difficult.

Underlying excess subcutaneous fat and frontalis muscle are completely exposed and are excised to debulk the nose and sculpt a nasal shape into the previously transferred tissues. 2007 Oct;120(5):1171-207; discussion 1208-16. doi: 10.1097/01.prs.0000254362.53706.91. Excess subcutaneous fat and frontalis, which lay over the skin graft, are exposed. Skin and soft tissue of the left cheek had been excised.
