The role of upper airway endoscopy in craniofacial malformations.

OBJECTIVE: To study the role of upper airway endoscopy (UAE) in craniofacial malformations in all different management approaches described in the literature. METHODS: A narrative review was performed, based on a search in pubmed. RESULTS: UAE use was reviewed over five domains: 1) Diagnosis of glossoptosis and endoscopic classification: drug-induced sleep endoscopy is recommended to graduate tongue base obstruction; there is still no consensus on the graduation system to be used. 2) Airway abnormalities: there is a high incidence of additional lesions in conjunction with glossoptosis. 3) Swallowing evaluation: a formal comparison with fluoroscopy (gold standard) has not yet been performed in this population. 4) Intubation: thin bronchoscopes allow intubation of small babies; moreover, intubation with rigid video-assisted laryngoscopes show a high success rate in this population. 5) Treatment outcome monitoring: there is no consensus on the ideal parameters to be checked. CONCLUSION: Some approaches have already been well established in the management of patients with craniofacial malformations, e.g. the endocopic evaluation of glossoptosis and associated lesions and its role as an intubation assistance tool, while others need to be subject of further research, e.g. its role in swallowing investigation and as a postoperative success control predictor.
