AAPS 104th Annual Meeting

Objectives:

•Measure prevalence and type of auricular anomalies in facio-auriculo-vertebral spectrum (FAV)

•Assess surgical management of FAV, focusing on microtia reconstruction

Methods:

•Retrospective review

•Patients with FAV seen by Craniofacial team or Genetics Dysmorphology (1999-2025)

•Cohort

on = 201

oMedian age at presentation 0.6 years [IQR 0.2–1.9]

oMedian age at last follow-up 9.5 years [IQR 3.9–15.2]

•Variables

oCraniofacial features

oSurgical history

•Analysis

oDescriptive statistics

oANOVA compared number of surgeries and age at surgery

Results:

201 patients with FAV

→ Mean of 3.1 surgeries (SD 3.9); 74% of patients (n=148) had ≥1 surgery

→ Mean of 1.9 craniofacial surgeries (SD 2.7); 61% of patients (n=123) had ≥1 craniofacial surgery

76% have microtia (n=153)

→ 31% underwent microtia reconstruction

•Mean of 3.7 reconstructive surgeries (SD 2.2)

•Autologous reconstruction was associated with more surgeries and later age at last surgery

48% have accessory tragi (n=96)

→ 66% underwent excision

•Mean age at surgery was 1.7 years (SD 2.3)

•Accessory tragi excision was the first surgery for 78% of these patients

Conclusions:

•Microtia was the most common craniofacial feature and a major driver of surgical intervention

•Reconstruction type influences surgical burden and timing

•Porous polyethylene enables fewer procedures at earlier ages

•Findings support counseling on variability in FAV presentation and reconstructive pathways
