[Nasal reconstruction: Decision tree based on 229 operated cases]

The Face is the most frequent localization for cutaneous carcinoma. The nose accounts for about 30% of these tumors. Nose tissue loss repair has to pursue 3 types of objectives: carcinologic, aesthetic and functional. The aim of this article is to identify a decision tree to guide the choice of surgical reconstruction technique based on localization and size of the defect.

We performed a retrospective analysis in Angers' CHU from 2013 to 2019 including 229 patients referred for cutaneous tumors excision in need of reconstruction. We analyzed the type of reconstruction, size of the tissue loss and localization of the defect in terms of nose aesthetic subunits.

Among the 229 patients included, the most frequent localization was nose tip (32%). 44% of patients were reconstructed with skin grafts or composite graft, 56% with flaps (48% local flaps and 4% association of both methods). Limited central resections of nose tip were reconstructed with skingraft. The Rybka flap and bilobed flap were the preferred choice for lateral reconstruction of nose tip. Largest tip defects were reconstructed using Rieger flap or forehead flap. The dorsum was often reconstructed with local flap: glabellar on the upper part, Rieger on the lower part. Lateral side was perfectly reconstructed with island flap. Nose wings needed framework: composite graft was the judicious choice in case of limited tissue loss whereas forehead flap with framework or Schmid-Meyer flap were chosen for larger defects.

Our past experience in nasal reconstruction has provided us with an original decision tree to guide surgeons in choosing the right reconstruction technique according to the size and localization of the defect.
