Should we consider the hemi-tip as a proper aesthetic subunit in a nasal reconstruction?
Background:
Defects involving several aesthetic subunits (ASUs) or lying at the junction of an ASU are challenging and require a complex reconstruction. This study aimed to describe the hemi-tip as a new ASU.
Material And Methods:
We conducted a retrospective study including patients who underwent a nasal reconstruction for lower nasal pyramid defects according to our modified ASU principle. Patients who suffered from a subtotal alar defect, which also involved <50% of the tip, were reconstructed after excising the remaining tissue of the hemi-tip subunit. An aesthetic evaluation was performed using a patient satisfaction scale and by independent raters.
Results:
From 2010 to 2014, 21 patients underwent a lower hemi-nose reconstruction. All patients had a full-thickness defect and underwent a reconstruction of the three layers of the nose. Sixty-four percent of our patients were very satisfied, 26% were satisfied, and only 10% were unsatisfied with their nasal tip appearance, with a mean score of 4.4/5. The nasal tip was also rated by independent raters with a mean score of 4.1/5.
Discussion:
Our results and experience showed that a midline scar between the two hemi-tips is inconspicuous. The majority of the defects involving only one side of the tip would benefit from the hemi-tip ASU reconstruction.
Conclusion:
We have modified the number of ASUs by considering the hemi-tip as a proper subunit.
