Tezuka M. . Comparison of recurrence rate and speech outcome between two different techniques for cleft palatal fistula closure: A retrospective cohort study . Journal of Cranio-Maxill2021 · 記述言語: 日本語 出版者・発行元: Journal of Cranio-Maxillofacial Surgery The aim of this retrospective cohort study was to compare the recurrence rate and speech outcomes between two techniques for palatal fistula closure of cleft palate (CP). Patients with CP who underwent secondary palatal fistula closure using the single hinge-flap method with double-breasted mattress suture (hinge-flap group) and those who were treated with the conventional sliding palatal flap method (sliding-flap group) were retrospectively evaluated for demographic and perioperative variables. Recurrence rate of palatal fistula, perceptual speech outcomes, and nasalance scores were further reviewed in patients who met the inclusion criteria. A total of 31 patients, 21 in the hinge-flap group and 10 in the sliding-flap group, were included in this study. The fistula recurrence rate in the hinge-flap group (0%) was significantly lower than that in the sliding-flap group (30.0%) (P = 0.027). In the speech assessment, hypernasality and nasalance scores decreased post-operatively in both groups and significance was observed in the hinge-flap group (P = 0.013, P < 0.001, respectively). Articulation disorders were significantly improved in the hinge-flap group (P = 0.001). Within the limitations of the study it seems that the single hinge-flap method with double-breasted mattress suture should be preferred whenever appropriate.

Evaluation of Articulatory Dynamics in Palatalized Articulation Using Electropalatography and Analys記述言語: 日本語 出版者・発行元: Oral Science International Aim: We aimed to visually evaluate the place of articulation of palatalized articulation (PA) using electropalatography (EPG) and to analyze the involvement of fistula and velopharyngeal function (VPF) as factors in the occurrence of PA. Methods: Ten patients with postoperative cleft palate and auditory PA were included. The test sounds were three alveolar sounds, [t], [d], and [s], with [a] inserted before each consonant and [a], [e], and [o] inserted afterward. The test sounds were consecutively recorded five times using the EPG, and a cumulative frequency pattern was created by accumulating the maximum contact frames at the time of each consonant production to visually determine the PA. The place of articulation in the cumulative frequency pattern was subsequently evaluated in detail. The relationship between the place of articulation and fistula and VPF was statistically analyzed. Results: All 10 patients had PA for any of the tested sounds. The place of articulation was divided into three patterns: anterior, middle, and posterior. The relationship between the place of articulation and the fistula for PA showed a significant difference between the groups with and without a fistula (U = 0, p = 0.0167, p < 0.05). The relationship with VPF showed no statistically significant differences. Conclusion: Using EPG to visually evaluate the place of articulation of the PA, we could divide it into three positions. Furthermore, there was an association between the place of articulation and fistula, suggesting that the place of articulation is more posterior in the presence of a fistula.
