Abstract

Objective: To evaluate the outcome of tongue-tie release on lingual motion of orthodontic patients with ankyloglossia Methods: Clinical intervention study, pre-post study on 36 patients, to evaluate the maximum distance between the upper and lower incisors when Comfortable mouth opening (CMO), the distance tongue tip extended towards the incisive papilla (TIP), the maximum distance Lingual-palatal suction (LPS), the free length of the tongue belly according to Kotlow, the amplitude of tongue movement forward (TIP/CMO) and backward (LPS/TIP), the degree of tongue-tie according to Tongue range of motion ratio forward (TRMR-TIP) and backward (TRMR-LPS) before and after surgery for 3 months. Results: CMO 48.42 ± 6.281 mm, postoperative 49.78 ± 7.007 mm, TIP before surgery 22.94 ± 4.119 mm, postoperative 30.28 ± 5.348 mm. LPS 19.06 ± 4.635 mm, 3 months postoperative 27.44 ± 5.278 mm. Free tongue belly length before surgery 17.75 ± 3.426 mm, 3 months postoperative 26.86 ± 5.161 mm. TIP/CMO before surgery 47.76 ± 8.38%, postoperative 61.36 ± 10.176%. LPS/TIP before surgery was 39.61 ± 9.35%, after surgery 55.60 ± 10.176%. Before surgery, 100% had a reduction in TRMR-TIP (grade 2 was 44.4%, grade 3 was 55.6%), after surgery this rate was 97.2% (grade 1 was 2.8%, grade 2 was 88.9%, grade 3 was 8.3%). Similarly, 100% of patients had a reduction in TRMR-LPS (grade 2 was 80.6%, grade 3 was 19.4%), after surgery this rate was 63.9% (grade 2). The difference was statistically significant with p<0.01 Conclusion: releasing the lingual frenulum effectively increases the level and amplitude of tongue movement.
