Individuals with trisomy 21 may have muscle hypotonia of the speech articulation organs, an enlarged protruding tongue positioned on the floor of the mouth, and a lack of lip closure. The stimulating palatal plate is an intraoral appliance that, associated with myofunctional therapy, aims to improve these children's habitual lip and tongue posture. This study aimed to present the cases of four male children with trisomy 21, with a mean age of 6.7 and a standard deviation of 7.8 months, who used the stimulating palatal plate in association with myofunctional therapy. The children used the plate for 6 months and did exercises based on the orofacial regulation therapy, and their parents received instructions on feeding them and removing deleterious oral habits. In the first session and at the end of the treatment, each child's face was video-recorded for 5 minutes at rest, and two researchers analyzed independently their habitual tongue and lip posture. Participants who began the treatment earlier and had the most severe postural changes had greater tongue and lip posture improvement.

BACKGROUND
In cleft palate repair, palate length is associated with improved speech outcomes. Although direct closure offers poor palatal lengthening, use of two opposing Z-plasties may reorient palatal musculature and lengthen the velum. The authors previously described a novel overlapping intravelar veloplasty to achieve longitudinal closure of the nasal mucosa with a single oral Z-plasty (1ZP), lengthening the palate in cadaver studies. This study aims to corroborate this finding in clinical cases.
METHODS
A retrospective comparative study of patients with a cleft palate was conducted. Patients underwent cleft palate closure with 1ZP or intravelar veloplasty with straight-line closure. Preoperative and postoperative measurements of the palate along four dimensions were recorded. Analysis was conducted on preoperative and postoperative measurements within and between groups using the Mann-Whitney-Wilcoxon or chi-square test.
RESULTS
Eighty-five patients were included (1ZP, n = 65; straight-line closure, n = 20). 1ZP increased soft palate length (SPL) by 33% ( P < 0.001) and total palate length (TPL) by 10% ( P < 0.001). Primary 1ZP increased SPL by 33% ( P < 0.001) and TPL by 10% ( P < 0.001). Secondary 1ZP increased SPL by 28% ( P < 0.001) and TPL by 8% ( P < 0.001). When comparing between primary and secondary 1ZP, 1ZP was equal with regard to percentage lengthening in SPL ( P > 0.9) and TPL ( P > 0.3). When compared with straight-line closure, 1ZP showed superior percentage lengthening in SPL ( P < 0.001) and TPL ( P = 0.038).
CONCLUSIONS
1ZP results in a statistically significant increase in palate length in both primary and secondary cleft palate repair. This technique provides an effective alternative in patients for whom 2ZP is not feasible.

This case report describes a dual full-arch rehabilitation focusing on a modified buccal incision for installation of four implants for full-arch rehabilitation of an edentulous maxilla. A modified buccal incision was performed in the subcrestal buccal region to promote direct access to the periosteum without incising the muscles in the region. For the installation of anterior implants, an 8.5 mm implant was locked in the cortical bone of the alveolar ridge and in the cortical bone of the floor of the pyriform cavity. The drilling point of the posterior implants was defined using the anterior implants as a visual reference, and the entry point could be visually estimated from the topography of the palatal surface of the maxilla. After bone leveling, the drilling enlargement sequence was carried out using drills that allowed the installation of long implants (18 mm). Straight mini-abutments were installed in the anterior implants and angled at 30º in the posterior implants. The flap was then perforated in the exact region where the mini-abutments were located. The buccal incision line was sutured with continuous 5-0 nylon suture. On the following day, aesthetic tests were carried out with teeth mounting. The patient presented minimal edema, and the lip motricity and smile width were completely preserved. The prosthesis was delivered five days after surgery. The suture was removed, and the prosthesis was installed while maintaining compression on the gingival tissue. The patient reported no pain during the prosthesis installation. The modified buccal flap enables implant placement for full-arch rehabilitation of an edentulous maxilla.

A 74-year-old male patient developed multiple infarcts of the brainstem and cerebellum, followed 14 months later by palatal tremor and bilateral vocal cord abduction paralysis, resulting in death due to type 2 respiratory failure. Pathologic analysis revealed old infarcts extending from the bilateral cerebellar cortices to the dentate nucleus, being more extensive on the right side, accompanied by Wallerian degeneration involving the left red nucleus, right central tegmentum tract, and inferior cerebellar peduncle, followed by pseudohypertrophy of the bilateral inferior olivary nuclei. These lesions, involving the Guillain-Mollaret triangle, may have been responsible for the palatal tremor. On the other hand, there were no evident causative lesions for the vocal cord abduction, including any in the nucleus ambiguus or posterior cricoarytenoid muscles. In this case it is possible that the dysfunction responsible for the palatal tremor may have affected the pathway from the central tegmentum tract, which is part of the Guillain-Mollaret triangle, to the vagus nerve arising from the nucleus ambiguus, which plays a role in vocal cord abduction, thus affecting the vocal cords and resulting in abduction paralysis.

[Effect of the Hyoid Bone Suspension Technique on the Preservation of Swallowing Function after Total Glossectomy and Pectoralis Major Musculocutaneous Flap Reconstruction for Locally Advanced Tongue Cancer].
Dysphagia is a major postoperative complication in patients with locally advanced oral cancer. In this case report, we describe the effect of the hyoid bone suspension technique on the preservation of swallowing function after total glossectomy and pectoralis major musculocutaneous flap reconstruction for locally advanced tongue cancer. Case: A 72-year-old Japanese male was diagnosed with advanced squamous cell carcinoma on the left side of his tongue(cT4aN2cM0, cStage ⅣA). Under general anesthesia, the patient underwent a tracheotomy, bilateral modified radical neck dissection type Ⅲ, total glossectomy, and reconstruction with a left pectoralis major musculocutaneous flap(PMMC flap). Intraoperatively, the PMMC flap was designed to have a heart shape of 11×6 cm and was elevated. Subsequently, holes were made at the lower edge of the mandible, and the hyoid bone was suspended and fixed to the mandibular border using 2-0 nylon sutures. The postoperative course was uneventful; the flap was completely engrafted and was in good condition. The hyoid bone suspension technique can reproduce the pharyngeal phase of swallowing, and the palatal augmentation prosthesis helps to improve food mass feeding and preserve the swallowing function.
