Comparison of microdebrider-assisted inferior turbinoplasty and submucosal resection for children with hypertrophic inferior turbinates

OBJECTIVES: The aim of this study was to compare the effectiveness and safety of microdebrider-assisted inferior turbinoplasty (MAIT) with submucosal resection (SR) for children with hypertrophic inferior turbinates. MATERIALS AND METHODS: One hundred and twenty children with chronic nasal obstruction due to hypertrophic inferior turbinates were enrolled. These children were randomly assigned to receive SR of the inferior turbinate (n=60) or MAIT (n=60). Ten children who did not appear to display any nasal discomfort served as normal controls. Surgical-outcome was evaluated with respect to four distinct parameters: nasal endoscopy, subjective assessment of nasal symptoms by the patient using a visual analogue scale, anterior rhinomanometry, and saccharin test. These evaluations were conducted before surgery and at 1 week, 1 and 3 months after surgery. RESULTS: In the SR group, turbinate edema was decreased significantly at 1 and 3 months after surgery (p<0.05). Nasal secretions and crusting were increased significantly (p<0.05) in the SR group at 1 week after surgery and then decreased significantly at 1 and 3 months after surgery. In the MAIT group, turbinate edema and nasal secretions were decreased significantly at 1 and 3 months after surgery (p<0.05). Nasal crusting was not observed after surgery. Subjective complaints including nasal obstruction, sneezing, rhinorrhea and hyposmia were significantly improved in both groups from 1 month after surgery (p<0.05). Rhinomanometric assessment did not reveal significant improvement until 3 months after surgery in both groups. Saccharin transit time was significantly increased (p<0.05) compared to baseline at 1 week after surgery in the SR group but was not significantly different in the MAIT group. CONCLUSION: MAIT and SR are both effective at relieving nasal obstruction due to the presence of hypertrophic inferior turbinates. MAIT is superior to SR with regard to preserving the nasal mucosa.
