A Novel Approach to Upper Pole Correction in Otoplasty: Addressing the Surprisingly Neglected Inferior Crus

BACKGROUND: Correction of prominent upper pole of ear is challenging, with high recurrence rates. Conventional otoplasty often fails to address the inferior crus, a key anatomical determinant of prominence. This study introduces a surgical technique targeting the inferior crus, a novel Inferior Crus Morphological Grading System (ICMGS) for diagnosis, and a new "upper pole declination angle" for objective assessment. METHODS: In this retrospective comparative study, 120 ears treated with a new technique were compared to 120 ears in a historical control group (traditional method). The new technique combines superior auricular muscle release, multi-loop inferior crus suturing, conchal reduction, and cartilage graft reinforcement. Outcomes were assessed via objective photogrammetry (including the upper pole declination angle) and blinded subjective scoring. RESULTS: The new technique demonstrated statistically superior results, with significantly greater reductions in upper pole declination angle, L1, and L2 distances (p
