Dr. Arturo Bonilla Microtia – Congenital Ear Institute is a San Antonio-based practice focused exclusively on pediatric microtia. Dr. Bonilla has performed microtia surgery for more than 30 years and is described by the institute as the world’s only surgeon dedicated exclusively to pediatric microtia. The site provides parents with information about the condition, including its causes, grades, associated aural atresia and hearing loss, and treatment choices.

The practice offers evaluation and surgical care for children with microtia, including ear reconstruction using rib cartilage, revision surgery, and guidance on candidacy and timing. It also explains how rib-cartilage reconstruction compares with Medpor or Su-Por, and discusses emerging 3D bioprinting research. For hearing needs, families can learn about bone-conduction devices, hearing options, and when ear canal surgery may be considered. The institute supports parents with practical resources on recovery, insurance, travel, hospital arrangements, and questions to ask a surgeon. It also provides patient stories, before-and-after photos, research updates, and information for referring physicians.
