**6. Conclusion**

We conclude that longitudinal care is required for patients with congenital microtia. This care involves the precise and regular evaluation of hearing levels from birth and investigation of malformations of the external auditory canal, middle ear, and inner ear, as well as cholesteatoma and abnormal occlusions occurring at predictable times in relationship with craniofacial growth and development. Microtia can be associated with other congenital abnormalities that are not obvious at birth. Furthermore, the external surface malformations frequently cause adverse psychosocial effects during children's growth process. Patients and their families should be supported in an unbiased manner when making decisions regarding which treatments are the most appropriate for the patient at a particular point of development, and this support must continue throughout the patients' life. In addition, means of hearing improvement should not simply be a difficult operation and instead involve careful consideration of the patient's interests and careful selection among the various options.
