Abstract
Rapid maxillary expansion (RME) may change speech sound parameters due to the enlargement of oral and nasal cavities. This study aimed to systematically review the current evidence on speech changes as a side effect of RME. An electronic search was conducted in nine databases, and two of them accessed the 'grey literature'. The eligibility criteria included clinical studies assessing orthodontic patients with maxillary transverse deficiency and the relationship with speech alterations without restricting publication year or language. Only interventional studies were included. The JBI Critical Appraisal Tool assessed the risk of bias. The initial search provided 4853 studies. Seven articles (n = 200 patients) met the inclusion criteria and were analysed. The primary source of bias was the absence of a control group in four studies. RME altered speech production by changing vowel fundamental frequency and fricative phoneme formant frequency. Shimmer and jitter rates changed in one and two studies, respectively. Two studies presented deterioration during orthodontic treatment, but speech improved after appliance removal. Despite the limited evidence, RME affects speech during and after treatment.

Comparison of rapid versus slow maxillary expansion on patient-reported outcome measures in growing patients: a systematic review and meta-analysis. Prog Orthod 2022; 23:47. [PMID: 36503984 PMCID: PMC9742070 DOI: 10.1186/s40510-022-00440-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2022] [Accepted: 10/08/2022] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND No systematic review and meta-analysis are present in the literature comparing patient-reported outcome measures (PROMs) in rapid maxillary expansion (RME) versus slow maxillary expansion (SME) in growing patients. OBJECTIVE The objective of this systematic review was to compare PROMs in RME versus SME in growing patients. MATERIALS AND METHODS Electronic search in PubMed (MEDLINE), Cochrane Library, Scopus, Embase, Web of Science, and OpenGrey was conducted. Only RCTs were included. Inclusion criteria were: growing patients in the mixed dentition or early permanent dentition, mild-to-moderate maxillary transverse deficiency, dental crowding, treatment with fixed expanders for rapid and slow maxillary expansion. Risk of bias was assessed using RoB 2. GRADE statement was performed. The mean of the differences (MD) and the risk ratio (RR) were used for the aggregation of data. A random effect model was applied. RESULTS Two articles with a total of 157 patients were finally included in the systematic review and meta-analysis. One article was at low risk of bias, while one was at risk of bias with some concerns. Pain presence was less, though not statistically significant, in SME patients (RR = 2.02, 95%CI from 0.55 to 7.49, P = 0.29, I2 = 95%, 2 studies, GRADE very low). Pain intensity was significantly lower in SME appliance in the first week of treatment (pooled MD = 0.86 favoring SME, 95%CI from 0.47 to 1.26, P < 0.0001, I2 = 6%, 2 studies, GRADE moderate). There were no significant differences between the two groups in difficulty in speaking, difficulty in swallowing, hypersalivation, difficulty in hygiene, and patient and parent satisfaction. CONCLUSIONS Pain intensity was significantly lower in SME compared to RME during the first week of treatment. For the following weeks, there were no differences in pain between the two protocols.

Abstract
Background. To evaluate the possible effects of Rapid Maxillary Expansion (RME), such as nasal breathing problems, middle ear function, Obstructive Sleep Apnea (OSA) in the otolaryngology field. RME has already been introduced in orthodontics to expand the maxilla of young patients affected by transversal maxillary constriction. Methods. A literature search was performed using different databases (Medline/PubMed, EMBASE, and CINAHL), from May 2005 to November 2021, according to the PRISMA guidelines. Results. The application of RME in children has shown good results on nasal function, reducing nasal resistances, independently from a previous adenotonsillectomy. These results are not only related to the increasing of nasal transverse diameters and volume, but also to the stiffening of airway muscles, enabling the nasal filtrum function and avoiding mouth opening, thereby decreasing respiratory infections. Positive effects have also been reported for the treatment of conductive hearing loss and of OSA, with the reduction of Apnea Hypopnea Index (AHI), possibly due to (i) an increased pharyngeal dimensions, (ii) a new tongue posture, and (iii) reduced nasal respiratory problems. Conclusions. Otolaryngologists should be aware of the indications and benefits of the RME treatment, considering its possible multiple beneficial effects.

Abstract
Rapid palatal expanders (RPEs) are commonly used in patients with cleft lip and palate (CLP) prior to secondary alveolar bone grafting (SABG). Their position and size can impede tongue movement and affect speech. This study assessed changes in perception and production of speech over the course of RPE treatment. Prospective longitudinal. Tertiary university-affiliated hospital. Twenty-five patients with unilateral CLP treated with Fan-type RPEs, and their parents. Patient and parent speech questionnaires and patient speech recordings were collected at baseline before RPE insertion (T1), directly after RPE insertion (T2), during RPE expansion (T3), during RPE retention (T4), directly after RPE removal but before SABG (T5), and at short-term follow-up after RPE removal and SABG (T6). Ratings for patient and parent questionnaires, first (F1) and second (F2) formants for vowels /a/, /i/, and /u/, and nasalance scores for non-nasal and nasal sentences, were obtained and analyzed using mixed model analyses of variance. Ratings worsened at T2. For the vowel /a/, F1 and F2 were unchanged at T2. For the vowel /i/, F1 increased and F2 decreased at T2. For the vowel /u/, F1 was unchanged and F2 decreased at T2. Nasalance was unchanged at T2. All outcome measures returned to T1 levels by T4. RPE insertion resulted in initial adverse effects on speech perception and production, which decreased to baseline prior to removal. Information regarding transient speech dysfunction and distress may help prepare patients for treatment.

Abstract
INTRODUCTION This study aimed to investigate voice changes in patients who had surgically assisted rapid maxillary expansion (SARME). METHODS Nineteen adult patients with maxillary transverse deficiency were asked to pronounce the sounds "[a], [ϵ], [ɯ], [i], [ɔ], [œ] [u], [y]" for 3 seconds. Voice records were taken before the expansion appliance was placed (T0) and 5.8 weeks after removal (T1, after 5.2 months of retention). The same records were taken for the control group (n = 19). The formant frequencies (F0, F1, F2, and F3), shimmer, jitter, and noise-to-harmonics ratio (NHR) parameters were considered with Praat (version 6.0.43). RESULTS In the SARME group, significant differences were observed in the F1 of [a] (P = 0.005), F2 of [ϵ] (P = 0.008), and [œ] sounds (P = 0.004). The postexpansion values were lower than those recorded before. In contrast, the F1 of [y] sound (P = 0.02), F2 of [u] sound (P = 0.01), the jitter parameter of [ɯ] and [i] sounds (P = 0.04; P = 0.002), and the NHR value of [ϵ] sound (P = 0.04) were significantly than the baseline values. In the comparison with the control group, significant differences were found in the F0 (P = 0.025) and F1 (P = 0.046) of the [u] sound, the F1 of the [a] sound (P = 0.03), and the F2 of the [ϵ] sound (P = 0.037). Significant differences were also found in the shimmer of [i] (P = 0.017) and [ɔ] (P = 0.002), the jitter of [ϵ] (P = 0.046) and [i] (P = 0.017), and the NHR of [i] (P = 0.012) and [ɔ] (P = 0.009). CONCLUSION SARME led to significant differences in some of the acoustics parameters.

Abstract
Any change in the maxillary position can affect the length of the vocal tract. This cross-sectional study aimed to assess the vocal acoustic parameters in 24 class III skeletal patients who underwent Le Fort I osteotomy for maxillary advancement. The vocal acoustic parameters (fundamental frequency, and jitter and shimmer perturbation indexes) were studied before, and at three, seven, and 10 months after maxillary advancement. The age and gender of the patients were the variables of the study. The amount of maxillary advancement was the predictive factor, and the changes in vocal acoustic parameters the study outcomes. Repeated-measures ANOVA were used to analyse the vocal acoustic parameters at different time points. Mean (SD) maxillary advancement was 3.5 (0.59) mm (range 3 - 6 mm). Data analysis did not demonstrate any significant correlation between the mean amount of maxillary advancement and changes in vocal acoustic parameters except for frequency of the 'i' sound. The results did not show a substantial change in the vocal acoustic parameters at 10 months after orthognathic surgery compared with baseline. These changed at three and seven months, but had returned to their baseline preoperative state 10 months after surgery.

Abstract
INTRODUCTION The association between the treatment of transverse maxillary deficiency and the recovery of hearing and voice functions has gained attention in recent years. OBJECTIVE This prospective controlled trial aimed to evaluate the effects of rapid maxillary expansion on hearing and voice function in children with non-cleft lip palate and bilateral cleft lip palate with transverse maxillary deficiency METHODS: 53 patients (26 non-cleft and 27 bilateral cleft lip palate; mean age, 11.1±1.8 years) requiring rapid maxillary expansion for correction of narrow maxillary arches were recruited for this trial. Eight sub-groups were established based on the degree of hearing loss. Pure-tone audiometric and tympanometric records were taken for each subject at four different time periods. The first records were taken before rapid maxillary expansion (T0), the second after expansion (T1) (mean, 0.8 months), the third after three months (T2) (mean, 3 months) and the fourth at the end of retention period (T3) (mean, 6 months). ANOVA and Tukey HSD post-hoc tests were used for data analysis. Additionally, voice analysis was done using an updated PRAAT software program in a computerized speech lab at T0 and T2. A paired-samplet-test was used for comparisons of mean values of T0 and T2 voice parameters within both groups. RESULTS Rapid maxillary expansion treatment produced a significant increase in the hearing levels and middle ear volumes of all non-cleft and bilateral cleft lip palate patients with normal hearing levels and with mild conductive hearing loss, during the T0-T1, T1-T2, T0-T2, and T0-T3 observation periods (p<0.05). The significant increase was observed in right middle ear volumes during the T0-T1, T0-T2 and T0-T3 periods in non-cleft patients with moderate hearing loss. For voice analysis, significant differences were observed only between the T0 and T2 mean fundamental frequency (F0) and jitter percentage (p<0.05) in the non-cleft group. In the cleft group, no significant differences were observed for any voice parameter between the T0 and T2 periods. CONCLUSION Correction of the palatal anatomy by rapid maxillary expansion therapy has a beneficial effect on both improvements in hearing and normal function of the middle ear in both non-cleft and bilateral cleft lip palate patients. Similarly, rapid maxillary expansion significantly influences voice quality in non-cleft patients, with no significant effect in BCLP patients.

Abstract
OBJECTIVE The aim of this systematic review was to assess the transverse skeletal effects of rapid maxillary expansion (RME) in pre and post-pubertal subjects. MATERIAL AND METHODS Five databases were searched till May 2018; Pubmed, Cochrane, Scopus, Lilacs and Web of science in addition to the manual search of other sources. There were no language restrictions. Methodological Index for Non-Randomized Studies MINORS was used to assess the quality and risk of bias of the trials included. RESULTS Six studies were finally included in the qualitative analysis. A meta-analysis wasn't performed due to the heterogeneity of methodologies and outcomes. All of the included studies showed drawbacks in their structure yielding weak evidence. On the short term, RME caused an increase in the maxillary and lateral-nasal widths in pre-pubertal subjects by 3.4 mm and 3.3 mm, and by 2.8 and 2.2 mm respectively in post-pubertal subjects. Although statistically insignificant, the maxillary width increase was more than that of the post-pubertal subjects by 0.6 mm. Over the long term, expansion produced permanent increases in the transverse dimensions of both the dento-alveolar and skeletal components of the maxilla and circum-maxillary structures in pre-pubertal subjects. The post-pubertal subjects presented with a statistically significant increase only in the later-nasal width by 1.3 mm than the untreated controls with no permanent increase in the skeletal maxillary width. CONCLUSION The literature is very deficient regarding the use of skeletal age as a reference in the treatment of skeletal crossbites using RME. Only weak evidence exists supporting the increased maxillary and lateral-nasal widths after tooth-tissue borne RME in pre-pubertal subjects, with these effects being less in the post-pubertal ones.

Abstract
OBJECTIVES To evaluate the association between maxillary arch dimensions and fundamental frequency and formants of voice in prepubertal subjects. MATERIALS AND METHODS Thirty-five consecutive prepubertal patients seeking orthodontic treatment were recruited (mean age = 11.41 ± 1.46 years; range, 8 to 13.7 years). Participants with a history of respiratory infection, laryngeal manipulation, dysphonia, congenital facial malformations, or history of orthodontic treatment were excluded. Dental measurements included maxillary arch length, perimeter, depth, and width. Voice parameters comprising fundamental frequency (f0_sustained), Habitual pitch (f0_count), Jitter, Shimmer, and different formant frequencies (F1, F2, F3, and F4) were measured using acoustic analysis prior to initiation of any orthodontic treatment. Pearson's correlation coefficients were used to measure the strength of associations between different dental and voice parameters. Multiple linear regressions were computed for the predictions of different dental measurements. RESULTS Arch width and arch depth had moderate significant negative correlations with f0 ( r = -0.52; P = .001 and r = -0.39; P = .022, respectively) and with habitual frequency ( r = -0.51; P = .0014 and r = -0.34; P = .04, respectively). Arch depth and arch length were significantly correlated with formant F3 and formant F4, respectively. Predictors of arch depth included frequencies of F3 vowels, with a significant regression equation ( P-value < .001; R2 = 0.49). Similarly, fundamental frequency f0 and frequencies of formant F3 vowels were predictors of arch width, with a significant regression equation ( P-value < .001; R2 = 0.37). CONCLUSIONS There is a significant association between arch dimensions, particularly arch length and depth, and voice parameters. The formant most predictive of arch depth and width is the third formant, along with fundamental frequency of voice.

Abstract
OBJECTIVE To evaluate the effects of rapid maxillary expansion (RME) on the vocal quality, maxillary central incisors, midpalatal suture, and nasal cavity in patients with maxillary crossbite. MATERIALS AND METHODS Coronal CT scans of 30 subjects (14 boys, 16 girls; mean age, 12.01 ± 0.75) were taken before RME (T0), and at the end of the expansion phase (T1). Voice samples of all patients were recorded with a high-quality condenser microphone (RODE NT2-A) on a desktop computer at T0 and T1. Statistical analyses were performed using a paired-sample t-test. The degree of association between the changes in the voice parameters and nasal width was assessed with Pearson's correlation. RESULTS RME treatment produced a significant increase in the transverse dimensions of the midpalatal suture and nasal cavity between T0 and T1 ( P < .05). The maximum F0 and jitter (%) results were shown to decrease statistically significantly from T0 to T1 ( P < .001 and P = .042, respectively). Between T0 and T1, shimmer (%) and shimmer (dB) exhibited statistically significant increases ( P = .037 and P = .019, respectively). CONCLUSIONS After RME therapy, voice quality differences were found to be associated with increases in nasal width.

Abstract
Objective
The aim of this study was to investigate the effects of rapid maxillary expansion (RME) on head posture, postural stability, and fall risk.
Materials and Methods
A sample of 51 adolescent patients was randomly divided into two groups. In the first group, which consisted of 28 patients (15 females and 13 males), RME was performed as a part of routine orthodontic treatment. The remaining 23 individuals (12 females and 11 males) served as the control group. Lateral cephalometric radiographs taken in natural head position, postural stability, and fall risk scores were obtained during the first visit. They were repeated on average 3.8 months and 3.5 months later for the study and control groups, respectively. The changes were analyzed using the Wilcoxon signed-rank test, paired samples t-test, Mann–Whitney U-test, and independent samples t-test.
Results
As a result of RME, a statistically significant decrease was detected in the fall risk score (P < 0.05) in the study group, while the head position and postural stability remained unchanged. For the control group, no significant changes were observed in all measurements.
Conclusions
The result of the present study suggests that RME has a capacity of improving fall risk.

OBJECTIVE To evaluate the effects of rapid maxillary expansion (RME) on vocal function in patients with bilateral maxillary crossbite. MATERIALS AND METHODS We designed our research as a prospective, controlled, clinical study. The treatment group and the control group each had 20 subjects for a total of 40 subjects. Acoustic voice samples were recorded from all patients at T1 and T2 by the Multi-Dimensional Voice Program (MDVP Model 5105) for acoustic analysis in Computerized Speech Lab (CSL). RESULTS No statistically significant differences were found between the treatment and control groups in the means of any parameters. CONCLUSIONS RME does not change vocal quality or resonance, so it can be safely used with patients.
