Vomer flap for Hard Palate repair is related to favorable maxillary growth in unilateral cleft lip and Palate
Clinical oral investigations, 2013Co-Authors: Yu-fang Liao, Ying-hsin Lee, Ruby Wang, Chiung Shing Huang, Philip Kuo-ting Chen, Yu Ray ChenAbstract:Objective Vomer flap repair is assumed to improve maxillary growth because of reduced scarring in growth-sensitive areas of the Palate. Our aim was to evaluate whether facial growth in patients with unilateral cleft lip and Palate was significantly affected by the technique of Hard Palate repair (vomer flap versus two-flap).

two stage Palate repair with delayed Hard Palate closure is related to favorable maxillary growth in unilateral cleft lip and Palate
Plastic and Reconstructive Surgery, 2010Co-Authors: Yu-fang Liao, Ruby Wang, Iying Yang, Claudia Yun, Chiung Shing HuangAbstract:Background Two-stage Palate repair with delayed Hard Palate closure is generally advocated because it allows the best possible postoperative maxillary growth. Nevertheless, in the literature, it has been questioned whether maxillary growth is better following use of this protocol. The authors therefore aimed to investigate whether stage of Palate repair, one-stage versus two-stage, had a significant effect on facial growth in patients with unilateral cleft lip and Palate. Methods Seventy-two patients with nonsyndromic complete unilateral cleft lip and Palate operated on by two different protocols for Palate repair, one-stage versus two-stage with delayed Hard Palate closure, and their 223 cephalometric radiographs were available in the retrospective longitudinal study. Clinical notes were reviewed to record treatment histories. Cephalometry was used to determine facial morphology and growth rate. Generalized estimating equations analysis was performed to assess the relationship between (1) facial morphology at age 20 and (2) facial growth rate, and the stage of Palate repair. Results Stage of Palate repair had a significant effect on the length and protrusion of the maxilla and the anteroposterior jaw relation at age 20, but not on their growth rates. Conclusions The data suggest that in patients with unilateral cleft lip and Palate, two-stage Palate repair has a smaller adverse effect than one-stage Palate repair on the growth of the maxilla. This stage effect is on the anteroposterior development of the maxilla and is attributable to the development being undisturbed before closure of the Hard Palate (i.e., Hard Palate repair timing specific).

Hard Palate repair timing and facial growth in cleft lip and Palate a systematic review
The Cleft Palate-Craniofacial Journal, 2006Co-Authors: Yu-fang Liao, Michael MarsAbstract:Abstract Objective: To evaluate the effect of timing of Hard Palate repair on facial growth in patients with cleft lip and Palate, with special reference to cranial base, maxilla, mandible, jaw relation, and incisor relation. Design: A systematic review. Methods: The search strategy was based on the key words “facial growth,” “cleft lip Palate,” and “timing of (Hard) Palate repair.” Case reports, case-series, and studies with no control or comparison group in the sample were excluded. Results: Fifteen studies met the selection criteria. All the studies were retrospective and nonrandomized. Five studies used cephalometry and casts, seven used cephalometry, and three used casts. Methodological deficiencies and heterogeneity of the studies prevented major conclusions. Conclusion: The review highlights the importance of further research. Prospective well-designed, controlled studies, especially targeting long-term results, are required to elucidate the effect of timing of Hard Palate repair on facial growth i...

effect of the effortful swallow and the mendelsohn maneuver on tongue pressure production against the Hard Palate
Dysphagia, 2013Co-Authors: Tatsuyuki Fukuoka, Kazuhiro Hori, Takahiro Ono, Kenichi Tamine, Sonoko Nozaki, Kenji Shimada, Noriyasu Yamamoto, Yoshihiro Fukuda, Kazuhisa DomenAbstract:Although effortful swallow and the Mendelsohn maneuver are commonly used in dysphagia rehabilitation, little is known about their effects on tongue-Palate pressure production. The purpose of this study was to investigate the effects of effortful swallow and the Mendelsohn maneuver on tongue pressure production. Fourteen healthy volunteers (10 men, 4 women; age range = 21–41 years) participated. Tongue pressures during dry swallow, water swallow, effortful swallow, and the Mendelsohn maneuver were measured using a sensor sheet system with five measurement points on the Hard Palate. Sequential order, duration, maximal magnitude, and the integrated value of tongue pressure at each measurement point were compared among the four tasks. Onset of tongue pressure at the posterior-circumferential parts occurred first in the Mendelsohn maneuver; that at the anterior-median part was earlier than at other parts in the effortful swallow. At all measurement points, tongue pressure duration was significantly longer in the Mendelsohn maneuver than in other tasks. Effortful swallow was most effective in increasing tongue pressure. The integrated value of tongue pressure at the posterior-circumferential parts in the Mendelsohn maneuver and at the median parts in the effortful swallow showed a tendency to increase. These results suggest that tongue pressure increases along a wide part of the Hard Palate in effortful swallow because the anchor of tongue movement is emphasized at the anterior part of the Hard Palate. The Mendelsohn maneuver provides prolonged and accentuated tongue-Palate contact at the posterior-circumferential parts, which might be important for hyoid-laryngeal elevation during swallowing.

Pattern of Tongue Pressure on Hard Palate During Swallowing
Dysphagia, 2004Co-Authors: Kazuhiro Hori, Takashi NokubiAbstract:Contact of the tongue against the Hard Palate plays an important role in swallowing. This study aimed to clarify the pattern of contact between the tongue and Hard Palate by analyzing tongue pressure produced in swallowing 15 ml of water by healthy subjects wearing an experimental palatal plate with seven pressure sensors. Tongue pressure was generated initially by close contact with the anteriomedian part of the Hard Palate, then with the circumferential part, and finally softly with the posteriomedian part. Tongue pressure reached a peak quickly, then decreased gradually before disappearing almost simultaneously at each measured part of the Hard Palate. Magnitude and duration were significantly larger in the anteriomedian part compared to the other six parts measured, and was significantly smaller in the posteriomedian part. No laterality was found in tongue pressure produced at the circumferential parts of the Hard Palate. Our findings indicate that the order of tongue contact against each part of the Hard Palate as well as duration and magnitude of tongue pressure are coordinated precisely during swallowing. These findings could aid assessment of the tongue movement of dysphagic patients during rehabilitation.
