OBJECTIVE
To explore the speech outcomes of adult patients with repaired cleft palate through subjective perception evaluation and objective acoustic analysis, and to compare the differences in pronunciation characteristics between speakers with complete velopharyngeal closure (VPC) and velopharyngeal insufficiency (VPI) patients.
PARTICIPANTS AND INTERVENTION
Subjective evaluation indicators included speech intelligibility, nasality and consonant missing rate, for objective acoustic analysis, we used speech sample normalization and objective acoustic parameters included normalized vowel formants, voice onset time and the analysis of 3-dimensional spectrogram and spectrum, were carried out on speech samples produced by 3 groups of speakers: (a) speakers with velopharyngeal competence after palatorrhaphy (n=38); (b) speakers with velopharyngeal incompetence after palatorrhaphy (n=70), (c) adult patients with cleft palate (n=65) and (d) typical speakers (n=30).
RESULTS
There was a highly negative correlation between VPC grade and speech intelligibility (ρ=-0.933), and a highly positive correlation between VPC and nasality (ρ=0.813). In subjective evaluation, the speech level of VPI patients was significantly lower than that of VPC patients and normal adults. Although the nasality and consonant loss rate of VPC patients were significantly higher than that of normal adults, the speech intelligibility of VPC patients was not significantly different from that of normal adults. In acoustic analysis, patients with VPI still performed poorly compared with patients with VPC.
CONCLUSIONS
The speech function of adult cleft palate patients is affected by abnormal palatal structure and bad pronunciation habits. In subjective evaluation, there was no significant difference in speech level between VPC patients and normal adults, whereas there was significant difference between VPI patients and normal adults. The acoustic parameters were different between the 2 groups after cleft palate repair. The condition of palatopharyngeal closure after cleft palate can affect the patient's speech.

Meta-Analysis
Characterization of the oral microbiota and the relationship of the oral microbiota with the dental and periodontal status in children and adolescents with nonsyndromic cleft lip and palate. Systematic literature review and meta-analysis.
OBJECTIVE
To identify the characteristics of the oral microbiota and the relationship of the dental caries and periodontal status in patients aged 0 to 18 years with non-syndromic cleft lip and palate (CLP).
MATERIALS AND METHODS
A systematic review of the literature was carried out. Five databases were consulted, including publications in English, Spanish and Portuguese. The evaluations of the quality of the observational studies and the experimental studies were carried out with the Newcastle-Ottawa scale and CONSORT guidelines, respectively. The risk of bias of the studies was determined using Rev Manager 5.4, and 5 publications were meta-analyzed.
RESULTS
The cariogenic microbiota of children and adolescents with cleft lip and palate was similar to that of children without clefts, although with higher counts of Streptococcus mutans and Lactobacillus spp. The periodontopathogenic microbiota was related to the presence of Campylobacter spp, Fusobacterium spp, Fusobacterium nucleatum, Prevotella intermedia/nigrescens, Parvimonas micra and Porphyromonas gingivalis, considered microorganisms with high pathogenic capacity. Heterogeneity was shown in relation to the microbiota and the type of fissure, presenting numerous microorganisms associated with the pre- and post-surgical condition (cheilorrhaphy and palatorrhaphy) such as Staphylococcus aureus, Streptococcus beta hemolyticus, Klebsiella pneumoniae and Klebsiella oxytoca, Moraxella catarrhalis, Candida spp, Candida albicans, Candida krusei and Candida tropicalis. The meta-analysis revealed that patients with cleft lip and palate were 2.03 times more likely to have caries than the control group (p<0.005).
CONCLUSION
In the microbiota, there was a great diversity of microorganisms that can vary according to the type of fissure and surgical interventions predisposing patients to a greater probability of dental caries, it is important to take into account the technique used to describe the oral microbiota in order to be able to compare the different studies.
CLINICAL RELEVANCE
Studying the microbiota and the relationship of dental caries and periodontal status in children and adolescents with cleft lip and palate can facilitate the comprehensive care of patients with these conditions.

Observational Study
OBJECTIVE
By measuring velopharyngeal structure and evaluating speech intelligibility, to explore and observe the association between velopharyngeal anatomy and speech outcomes in these patients.
METHODS
Thirty-one adult patients with velopharyngeal insufficiency after the primary palatoplasty aged 18 to 35 years (mean 22.03 years) were enrolled as the study group. The patients had significant hypernasality and audible nasal emission. The degree of velopharyngeal closure assessed by electronic nasopharyngeal fiberoptic endoscopy was grade III. Cephalometric analysis was performed on lateral cephalograms to measure velopharyngeal structure, including hard palate length (ANS-PNS), velar length (PNS-U), pharyngeal depth (PNS-PPW), and oropharyngeal airway space (U-MPW). Their speech intelligibility was evaluated through the Mandarin Chinese speech intelligibility test, and each speech sample was examined by 2 speech and language pathologists. The results were assessed with the SPSS 23.0 software package, and regression analysis was used to examine the relationship between velopharyngeal structure and speech outcomes.
RESULTS
A significant negative correlation was confirmed between speech intelligibility and pharyngeal depth. Pharyngeal depth also showed a linear relationship with speech intelligibility, and there was no significant correlation between speech intelligibility and other measures (hard palate length, velar length, oropharyngeal airway space).
CONCLUSIONS
In the velopharyngeal anatomy, only pharyngeal depth was associated with speech intelligibility in adult patients with severe velopharyngeal insufficiency, this is consistent with our clinical observation. It suggests that appropriate reduction of pharyngeal depth during palatopharyngoplasty may have a good effect on the speech recovery in patients with cleft palate and patients with velopharyngeal insufficiency after palatorrhaphy.
