“…So in the previous study, we attempted to determine appropriate tongue blade length for Japanese pediatric patients with CP and mandibular micrognathia and concluded that it was difficult to predict the distance from the tongue blade base to the posterior pharyngeal wall (Dis) on the basis of the patient's age or weight at the time of surgery, which could be measured preoperatively, and as the minimum Dis value in the MG group was 55 mm, preparing a tongue blade of approximately 50 mm in length, which is shorter than the current minimum specifications, might be appropriate when fitting a Dingman Mouth Gag for Japanese pediatric patients with CP and mandibular micrognathia [1].…”

Objective: The purpose of this study is to determine the appropriate tongue blade width of Dingman Mouth Gag for Japanese cleft palate (CP) patients with mandibular micrognathia. Methods:We investigated 22 isolated CP patients whose bilateral lower first deciduous molars (D) had erupted. Patients were divided into the micrognathia (MG) group (10 patients) and normognathia (NG) group (12 patients). Following items were investigated: gender, age (A) and weight (W) at the time of surgery, distance between the top of lingual cusps of bilateral lower Ds (D1), distance between the lingual deepest points of bilateral lower Ds (D2) and perpendicular distance from the midpoint of incisal margin of bilateral lower deciduous central incisors to the line connecting the most distal points of bilateral lower Ds (D3).Results: There were significant differences in A and D3 between the groups. There were significant correlations between W and D3, D1and D3, D2 and D3 in the MG group. Excluding the attachment part to the mouth gag frame, we had assumption that the position 13.2 mm (equal to the median value of D3 in the MG group) posterior from the tip of the tongue blade would be corresponding to the D2 measurement point. The actual measured value for the small tongue blade width (D4) was 20.5 mm, smaller than median value of D2 in the MG group. Conclusions:We conclude the width of small tongue blade of Dingman Mouse Gag currently in use may be appropriate and no modification is required for the width.
