Medicolegal Pitfalls

  • A child affected with Treacher Collins syndrome needs multidisciplinary care starting from birth and throughout most of his or her life. As in any multidisciplinary treatment that involves many specialists, one center or team must coordinate a treatment plan. Therefore, each child should always be referred to a craniofacial center or a multidisciplinary craniofacial team as soon as possible. The team will develop and present a treatment plan for the child to the family. If a child is not referred to such a center or team, existing or potential problems may be overlooked. All craniofacial centers in the country are staffed with or have the ability to consult with a specialist for each discipline that is involved in the care for a child with Treacher Collins syndrome. A geneticist should be involved from the beginning, and a careful genetic examination should involve all first-degree relatives in order to specify a risk of recurrence. The team should also have a neonatologist, a pediatrician, a craniofacial or plastic surgeon, an otorhinolaryngologist, an ophthalmologist, a pediatric dentist and orthodontist, a speech pathologist, and a psychologist.
  • A treatment plan should be presented to the family as early as possible and should include a timeline for each planned procedure, its benefits and risks, and its anticipated costs. Informed consent should be a part of every step of the treatment. If legal issues arise, a physician's defense must include detailed records of each discussion with the family, including all of the many potential risks and benefits.
