Three-Stage Paramedian Forehead Flap Reconstruction of the Nose Using the Combination of Composite Septal Pivot Flap with The Turbinate Flap and L-Septal Cartilaginous Graft - a Case Report.

Abstract

Nasal basal cell carcinomas are the most common malignant tumors of the facial skin, which predilectively affect areas exposed to sunlight, including the nasal area. After their radical removal, there is a variable complex defect of the affected area (defect of all 3 layers of the nose) or even a composite defect (it also occupies the adjacent soft tissues around the nose), which are usually used to reconstruct this area. A 73-year-old female patient with recurrent infiltrative basal cell carcinoma of the left nasal ala underwent four re-excisions before histologically verified free margins without the presence of the tumor. The result was a composite defect that occupied the top of the dome of the right nostril, the entire left half of the soft nose, including the base of the wing, part of the upper lip, and a defect of the adjacent face area of 9 × 5cm. In the first phase, the left cheek and upper lip were reconstructed by advancement French plasty and coverage of the two residual skin defects with full-thickness skin graft. One month later, during the second phase of reconstruction, the flap was re-elevated, shifted and rotated, and a three-stage nasal reconstruction was started using a composite septal pivotal flap and left turbinate flap for inner lining reconstruction, and the nasal skeleton was reconstructed with a cartilaginous L-graft from the 6th rib, septal and conchal cartilages. The skin cover of the nose was reconstructed with the left paramedian forehead flap, which was thinned during the second stage with the simultaneous widening of the bottom of the left nostril by the transposition flap, during the third stage the flap pedicle was removed. In the reconstruction of a complex defect of the nose and its surroundings, it is first necessary to create a stable platform on which the reconstruction of the nose itself will be performed. To achieve an excellent functional and aesthetic result of nose reconstruction, it is appropriate to use a three-stage forehead flap. In this paper, we describe a unique method of nasal reconstruction - a combination of a septal pivotal flap with a turbinate flap to reconstruct the inner lining in conjunction with an L-graft to ensure a stable nasal skeleton and forehead flap to reconstruct the skin cover.
