RESUMO
Hypoglossia is a rare congenital anomaly resulting in a small rudimentary tongue. It is classified under the oromandibular-limb hypogenesis syndrome and can be found in isolation (Type IA) but is more often associated with other congenital disorders, such as limb defects. Isolated hypoglossia cases are rare, and while feeding disorders are common, in some cases, neonatal airway obstruction is the most problematic. In the present report, we discuss two cases of newborns presenting with hypoglossia without limb deformities or visceral anomalies: one new case and a 10-year update of a previously reported case. These two cases highlight the variability in presenting symptoms and the challenges in diagnosis and management of a rare clinical entity. We focus on the discussion of early diagnosis, multidisciplinary management, and shared decision-making, with emphasis on the current therapeutic strategies available to the clinician and their limitations during the neonatal period. Early surgical multivector mandibular distraction osteogenesis can be proposed with minimal short- and long-term morbidity, pending a consistent follow-up. This clinical entity will require multidisciplinary team care into adult years.
