Assessing the Current State of Microtia Reconstruction in the United States.

Objective: Microtia is a congenital ear deformity with variability in surgical techniques and tools across surgeons pursuing an autologous reconstruction. Different techniques have emerged over time, and surgeons opt for various tools to aid in creating the complex three-dimensional cartilaginous ear framework. The purpose of this study was to understand the current state of microtia reconstruction in the United States.
Methods: Microtia surgeons affiliated with the nonprofit, Ear Community, were invited to complete a 20-item survey. Data were collected on demographic information regarding surgeons, considerations when approaching microtia repair in patients, and techniques and comfort levels. Additional data were collected on materials, tools, flaps, and skin grafts used for reconstruction.
Results: Twenty-two surgeons responded to the survey reporting 3 different techniques learned and utilized in practice including the Brent, Nagata, and Firmin techniques. About two-thirds of surgeons were "extremely comfortable" with their techniques and one-third were "extremely uncomfortable" or "somewhat uncomfortable." Most respondents reported using a tunneled temporoparietal fascial flap or a posterior fascial flap along with a full-thickness skin graft for the second stage (ear elevation). Most surgeons utilized a combination of scalpels and gouges when carving the ear framework along with sutures or wire.
Conclusions: This study highlights the current state of autogenous microtia reconstruction underscoring the variability in approaches and preferences. These data may guide future directions that aim to improve patient outcomes. Surgeons may gain insight into different practices and choose to adopt different aspects to enhance their surgical approach.
