Community Education

Over thirty years Dr. Bonilla has brought microtia education beyond the clinic — presenting at national conferences, speaking to medical residents, visiting school classrooms, and participating in family community events. The photographs below document a cross-section of that engagement.

At the Microtia Congenital Ear Institute

Dr. Bonilla has treated one condition exclusively for thirty years — pediatric microtia reconstruction.

Every child who comes to Dr. Bonilla’s practice has microtia. Every consultation is unhurried. Every surgical plan is specific to that child’s grade, anatomy, and age.

An entire office wall is covered floor to ceiling with colorful children’s drawings, handwritten letters, and thank-you cards sent to Dr. Arturo Bonilla from microtia surgery patients around the world.

The Clinical Framework

The Six Questions That Actually Define Surgical Excellence in Microtia

These questions are not rhetorical. Every one of them has a verifiable answer — and the answers matter for long-term outcomes.

1

Does the surgeon perform microtia exclusively — or as one procedure among many?

This is the single most important question and the one most families do not think to ask. A surgeon who performs microtia reconstruction once a month alongside rhinoplasties, facelifts, and otoplasties is fundamentally different from one who has performed it every week for thirty years and nothing else.

Repetition drives refinement. Pattern recognition in the operating room — knowing when cartilage behaves unexpectedly, when a grade presents differently than its classification suggests, when a child’s anatomy requires a modification to the standard approach — comes only from concentrated, exclusive volume. A surgeon who treats microtia as one condition among many cannot accumulate that depth of experience regardless of their general surgical skill. This depth of experience also defines what is possible in revision microtia surgery — among the most demanding cases in this field.

AB
Dr. Arturo Bonilla has performed pediatric microtia reconstruction exclusively since founding the Microtia Congenital Ear Institute in San Antonio in 1996. He has not performed any other surgical procedure since that year. Every patient he evaluates has microtia. Every surgery he performs is ear reconstruction.
2

How many microtia reconstructions has the surgeon performed — and on how many pediatric patients specifically?

Volume matters in reconstructive surgery. It matters more in microtia than in most procedures because the condition is rare — affecting approximately 1 in 6,000 to 12,000 births — which means even surgeons who treat it regularly accumulate cases slowly compared to higher-incidence conditions.

Ask any surgeon you consult how many microtia reconstructions they have performed on pediatric patients. Then ask if those results are published in peer-reviewed literature where the methodology and outcomes have been independently reviewed.

AB
Dr. Bonilla’s clinical experience is documented in peer-reviewed literature. His 2018 publication in the Facial Plastic Surgery Clinics of North America“Pediatric Microtia Reconstruction with Autologous Rib: Personal Experience and Technique with 1,000 Pediatric Patients with Microtia” — documents his surgical series. Families have traveled to his practice from all 50 states and more than 50 countries.
3

Which reconstruction technique does the surgeon use — and what does the published evidence show about long-term outcomes?

There are three main approaches to microtia reconstruction: natural rib cartilage, porous polyethylene synthetic implant (Medpor or Su-Por), and auricular prosthesis. The technique matters enormously for long-term outcomes. Ask any surgeon which technique they use — and why.

Published evidence: A 2025 systematic review and meta-analysis of 11 studies covering 3,816 patients — published in the Cleft Palate Craniofacial Journal — found that porous polyethylene implants had a framework exposure rate approximately 6.97% higher than autologous rib cartilage reconstruction, along with higher rates of infection and redo procedures. A 2022 systematic review found complication rates of 15% for Medpor versus 2% for rib cartilage. A national survey of American Society of Plastic Surgeons members found that approximately 91.3%¹ of surgeons who perform microtia reconstruction choose autologous rib cartilage as their technique of choice.
AB
Dr. Bonilla uses natural rib cartilage exclusively. He does not perform Medpor or Su-Por implant reconstruction. The reconstructed ear is built from the child’s own living tissue — it grows with the child, cannot be rejected, and carries no permanent fracture or exposure risk.
4

Has the surgeon published peer-reviewed research on microtia reconstruction?

Peer-reviewed publication is the mechanism by which the surgical community evaluates and validates a surgeon’s technique and outcomes. A surgeon who has not published their results has not submitted their outcomes to independent scrutiny. Ask for PubMed ID numbers — not just claim of publication.

AB
Dr. Bonilla is the principal author of Chapter 21: Surgical Management of Microtia and Congenital Aural Atresia in the standard Pediatric Otolaryngology training textbook used in residency programs nationally. He is also the principal author of the microtia chapter in Operative Otolaryngology Head and Neck Surgery, 3rd Edition. His 1,000-patient series is published in the Facial Plastic Surgery Clinics of North America (PMID: 29153189).
5

Does the surgeon treat children exclusively — and from what age through what age?

Microtia reconstruction in adults is technically different from pediatric reconstruction. The cartilage behaves differently. The anatomy is fixed rather than developing. And the psychological stakes of surgery differ significantly between a child approaching school age and an adult who has lived with microtia for decades. Ask whether the surgeon’s experience is primarily pediatric or mixed adult and pediatric.

AB
Dr. Bonilla treats pediatric patients exclusively — from newborns evaluated for hearing support through age 17. He does not treat adult microtia patients. His entire clinical experience is concentrated in the age range where reconstruction has the greatest developmental and psychological impact.
6

Can the surgeon show long-term results — not just recent cases?

Any surgeon can show impressive recent results. The more meaningful question is what results look like five, ten, and fifteen years after surgery — when the reconstructed ear has grown with the child, when the cartilage framework has matured, and when the full outcome is visible. Ask specifically to see results from cases performed more than ten years ago.

AB
Dr. Bonilla has been performing microtia reconstruction since 1996. Patients reconstructed in the early years of his practice are now adults in their twenties and thirties. His before and after gallery includes 70 patient cases spanning Grade II through Grade IV microtia. All photographs are published with explicit written patient and family consent.

Families travel to San Antonio from across the United States and more than 50 countries

Dr. Bonilla has treated microtia patients from over 50 countries across Europe, Asia, Russia, and beyond.
International Families

Dr. Bonilla’s team has coordinated care for families from more than 50 countries. The office assists with documentation needed for medical travel. Telehealth consultations are available before families travel to San Antonio.

“Dr. Bonilla does not advertise himself as the best microtia surgeon. He has spent thirty years letting his surgical record, his published research, and his patients’ outcomes make that case. The six criteria on this page are not a marketing framework — they are the questions he would ask if he were a parent choosing a surgeon for his own child.”

3D Bioprinting Clinical Trial

Dr. Bonilla served as a clinical investigator in one of the first FDA-authorized efforts to bring 3D-bioprinted living tissue ear reconstruction into patient care.

The first procedure in the clinical trial was performed by Dr. Bonilla in March 2022. Results were reported on the front page of The New York Times on June 2, 2022, and covered by more than 90 media outlets across six continents — including BBC News, Reuters, NBC News, CBS News, The Guardian, Scientific American, and MIT Technology Review.

The clinical trial evaluated a 3D-bioprinted living tissue ear implant incorporating the patient's own cartilage cells — a potential alternative to rib cartilage reconstruction. Dr. Bonilla remains actively engaged in following developments in this field.
