To address this, alternative relaxing incisions were designed. Thus, this study aimed to compare the effectiveness of palatal relaxing incisions versus nasopharyngeal relaxing incisions in enhancing postoperative outcomes.</p><p><strong>Materials and methods: </strong>A retrospective cohort study was conducted, involving a total of 120 patients divided into three groups: 40 patients have received modified Furlow palatoplasty with nasopharyngeal relaxing incisions (M.F + N.P.I palatoplasty), and 40 patients who received modified Furlow palatoplasty with palatal relaxing incisions (M.F + P.R.I palatoplasty). The other 40 patients received original Furlow palatoplasty without relaxing incisions (F palatoplasty). Data collected included gender, cleft type, cleft width, age at repair, velopharyngeal function, presence of palatal fistula, and follow-up. The chi-square test compared frequencies of sex, cleft type, postoperative fistula, and velopharyngeal outcomes across groups. The Mann-Whitney and independent t-tests compared mean values, with statistical significance set at p < 0.05.</p><p><strong>Results: </strong>The mean age at repair was similar across groups, with follow-up periods ranging from 5 to 11 years. No significant differences were found among the M.F + N.P.I and M.F + P.L.I groups regarding gender, cleft type, cleft width, and age at repair. However, the F group had a significantly narrowest cleft width compared to the other groups. Postoperative outcomes showed no significant differences in velopharyngeal function among the three groups, but the F group had a significantly higher rate of palatal fistula (32.5%) compared to the M.F + P.L.I (10%) and M.F + N.P.I (7.5%) groups.

The screws were placed using a self-drilling protocol in one quadrant and a pre-drilling protocol in the opposing quadrant decided via coin toss randomization. Stability was examined at the time of placement and 1,2, 3 and 4 months thereafter, using the Resonance Frequency Analysis method with the Osstell Beacon ^TM device.
