OBJECTIVES: Questionnaires are widely used in medicine to collect essential patient information, identify disease etiologies, and assess treatment outcomes. In orthodontics, questionnaire-based assessments facilitate the identification of factors associated with dentoalveolar anomalies and myofunctional disorders. Adenoid hypertrophy (AH) is a significant contributor to the development of these conditions. However, inadequate postoperative follow-up may allow myofunctional disorders to persist or progress, despite surgical treatment. A comprehensive evaluation of factors affecting general and oral health may improve diagnostic accuracy, treatment outcomes, and interdisciplinary collaboration. This study aimed to assess the condition of children after surgical treatment for AH, determine the need for orthodontic intervention and associated risk factors, and evaluate the extent of interdisciplinary collaboration in identifying and managing myofunctional disorders through a questionnaire survey and medical record analysis. MATERIALS AND METHODS: This retrospective observational questionnaire-based study included 220 children aged 5-8 years who had undergone surgery for AH. Medical records and questionnaires completed by the children's legal guardians were analyzed. RESULTS: The findings indicate that a considerable proportion of children continued to experience respiratory, functional, and speech-related complaints after adenoidectomy. Parents frequently reported persistent mouth breathing, pronunciation difficulties, and signs suggestive of myofunctional disorders, despite previous surgical treatment. CONCLUSIONS: Persistent postoperative complaints were identified in a proportion of children, including impaired nasal breathing, harmful oral habits, pronunciation difficulties, and parent-reported signs suggestive of myofunctional disorders. The findings also showed insufficient interdisciplinary follow-up after adenoidectomy, particularly regarding referrals to orthodontists, dentists, speech therapists, and specialists in myofunctional therapy.
