The book provides a framework for diagnosis and treatment of the complex facial deformities found in craniofacial microsomia and Treacher Collins syndrome. These conditions are difficult to treat due to their complexity and variable presentation. The deformities may be mild or severe and merely cosmetic to life-threatening in nature. These conditions often manifest as complex facial deformities that require multiple surgical interventions. Timing is critical when treating these patients and knowing and choosing the correct operation is key to successful outcomes. This work provides a comprehensive approach in treating these complex patient populations, seeking to answer the following questions: When to operate versus when to wait? If operating is required what operation should be performed? What is the best orthodontic approach to the associated dental deformities that develop with these conditions? How should sleep apnea be evaluated and treated in this population? What is the best management for feeding patients with these conditions? Written by experts in the field, Craniofacial Microsomia and Treacher Collins Syndrome: Comprehensive Treatment of Associated Facial Deformities aims to provide the reader with literature based best practices in treating these children from the NICU through childhood and into adulthood.
