“…Clinically, RPDs with similar designs could disturb patients’ speech production by varying degrees; thus, speech impairment after RPD insertion is dependent on both RPD design and patient factors. Although the relationship between speech production and deformation of the oral cavity in patients after tumor excision has been evaluated with and without prostheses, few studies have investigated the relationship between RPDs and speech production, focusing on morphological characteristics of the patients’ oral cavities [30-32]. Brunner et al [33, 34] reported that the shape of the palate affects acoustic variability.…”

Background/Aims: Speech impairment during the initial phase of removable partial denture (RPD) treatment can prevent patient adaptation to RPDs. This study was undertaken to investigate the influence of oral morphology on speech production in subjects wearing RPDs with major connectors. Methods: Two types of connectors were fabricated for 17 subjects with normal dentitions: covering the middle palate (M-bar) and the anterior/posterior palate (AP-bar). Four target sounds ([∫i], [t∫i], [çi], and [ki]) were evaluated under 3 recording conditions: no connector, M-bar, and AP-bar. The mean appearance ratios of correct labels (MARCs) were calculated as parameters representing speech production accuracy with the speech evaluation system. Subgroup analysis was conducted based on palate height, dental arch width, and front space volume of the oral cavity. Results: Based on the multiple linear regression test, a significant association was found between the MARCs of [∫i] with M-bar and front space (p = 0.036). In the subgroup analysis, the AP-bar had a significant effect on the MARCs of [∫i] among subjects with high palate (p = 0.026), narrow arch (p = 0.004), and small front space (p = 0.014). Conclusion: RPDs with major connectors could disturb speech production among patients with high palates, narrow arches, and small front spaces.

“…The tongue is an organ with specific, accurate, and particular functions related to speech, voice, swallowing, and chewing. Its excision implies articulatory prejudice in most consonants and vowels [3], unbalanced resonance with predominant hypernasality [4], alterations in vocal quality [5], swallowing impairments that lead to dysphagia in all phases of swallowing [6, 7], and the impossibility or difficulty of performing mastication [7]. …”

Maintaining oral function in patients undergoing glossectomy boosts interventions such as prosthetic rehabilitation. However, current literature still fails in the presentation of results of prosthetic rehabilitation in relation to speech or swallowing. The objective of this research is to evaluate the effectiveness of prosthetic rehabilitation on voice, speech, and swallowing in patients undergoing glossectomy by performing a systematic literature review and meta-analysis of individual cases. Studies were identified by relevant electronic database and included all dates available. The criteria used were sample with any n; resection due to malignant tumors, restricted to tongue and/or floor of mouth; type of prosthetic rehabilitation; and description of the oral functions outcomes with prosthesis. For the meta-analysis of individual data, associations between the variables of interest and the type of prosthesis were evaluated. Thirty-three of 471 articles met the selection criteria. Results on speech and/or voice and swallowing were reported in 27 and 28 articles, respectively. There were improvement of speech intelligibility and swallowing in 96 patients and in 73 patients, respectively, with prosthesis. Based on the available evidences, this article showed that prosthetic rehabilitation was able to improve oral functions and can be a strategy used with surgical reconstruction in selected cases.

“…Although there is an infinite number of formants, the first 3 are the most important for the acoustic description and identification of the vowels. 4,[7][8][9][10] In some of these studies, the improvement of communication was evaluated only by the subjective impressions of the physicians, patients, or both, without the use of tools or specific protocols for this purpose, thus not allowing an intersubject and/or intrasubject comparison of these data. 3 After tongue resections, changes in configuration and volume of the vocal tract generate resonant and articulatory alterations, consequently affecting the intelligibility of these patients' speech.…”

“…Most studies considered limited and heteroge-neous samples, which makes it difficult to reach conclusions based on their findings. 4,[7][8][9][10] In some of these studies, the improvement of communication was evaluated only by the subjective impressions of the physicians, patients, or both, without the use of tools or specific protocols for this purpose, thus not allowing an intersubject and/or intrasubject comparison of these data. 11 The objective of this study was to assess the influence of the palatal augmentation prosthesis on the speech intelligibility and acoustic spectrographic characteristics of the formants of oral vowels in Brazilian Portuguese, specifically the first 3 formants, in glossectomy patients.…”

Objective: To assess, in patients undergoing glossectomy, the influence of the palatal augmentation prosthesis on the speech intelligibility and acoustic spectrographic characteristics of the formants of oral vowels in Brazilian Portuguese, specifically the first 3 formants (F1 [/a,e,u/], F2 [/o,ó,u/], and F3 [/a,ó/]).Design: Speech evaluation with and without a palatal augmentation prosthesis using blinded randomized listener judgments.Setting: Tertiary referral center.Patients: Thirty-six patients (33 men and 3 women) aged 30 to 80 (mean [SD], 53.9 [10.5]) years underwent glossectomy (14, total glossectomy; 12, total glossectomy and partial mandibulectomy; 6, hemiglossectomy; and 4, subtotal glossectomy) with use of the augmentation prosthesis for at least 3 months before inclusion in the study.Main Outcome Measures: Spontaneous speech intel-ligibility (assessed by expert listeners using a 4-category scale) and spectrographic formants assessment.Results: We found a statistically significant improvement of spontaneous speech intelligibility and the average number of correctly identified syllables with the use of the prosthesis (P Ͻ .05). Statistically significant differences occurred for the F1 values of the vowels /a,e,u/; for F2 values, there was a significant difference of the vowels /o,ó,u/; and for F3 values, there was a significant difference of the vowels /a,ó/ (PϽ .001). Conclusions:The palatal augmentation prosthesis improved the intelligibility of spontaneous speech and syllables for patients who underwent glossectomy. It also increased the F2 and F3 values for all vowels and the F1 values for the vowels /o,ó,u/. This effect brought the values of many vowel formants closer to normal.
