“…As a result, it has apparently been shown that open-space obturators with low medial wall heights are more effective. [7] While the procedures for treating patients with oral-nasal communication are the same as those for creating conventional prostheses, it is still necessary to plan for each case separately and take extra precautions when taking impressions and fitting the appliance. During their rehabilitation, these patients receive equipment that allows them to carry on with normal daily tasks like talking and eating.…”

Maxillary jaw abnormalities can be traumatic, acquired, congenital, developmental, or surgical, and they can have an impact on the mouth cavity and nearby anatomical tissues. If the soft palate and/or hard palate are lost whole or partially, the remaining tissues will have an inadequate structure or will no longer function as they once did. Defects can lead to nasal reflux during deglutition and influence speech production by affecting articulation and airflow. This study aims to explore postoperative oroantral or oral-nasal communication for patients who underwent partial maxillectomy and received prosthetic rehabilitation. The complete denture was fabricated with an extension into the defect. As a result, this permanent prosthesis improved the patient's masticatory function, speech clarity, and general quality of life.

Aim:The selection of the appropriate denture base material for obturator fabrication is essential as it significantly affects the overall clinical outcomes. Flexible acrylic resin obturators provide an excellent alternative to the traditionally used PMMA obturators, due to its` impeccable esthetics, comfort, retention and adaption to the constantly mobile oral tissues. Subjects and methods: This is a randomized, crossover study. Patients included in the study were randomly allocated into one of two groups (group AB and group BA). Each of the patients included in the study had a conventional PMMA (device A) and a flexible (device B) obturator constructed for them to be used sequentially each for two weeks. The patients filled a 5-point Likert scale obturator functioning scale after two weeks of using each type of obturator. The data were statistically analyzed. Results: The results of this study demonstrated that device B which is an obturator made of flexible acrylic resin provided a significantly higher patient satisfaction compared to device A, which is constructed of PMMA. Conclusion: Flexible acrylic resin obturators are more satisfying to maxillectomy patients than PMMA obturators.Key to attaining the desired outcomes in the rehabilitation of maxillectomy patients is the utilization of an obturator (3) . The selection of the appropriate denture base material for obturator fabrication is

Comparison of Praat and Computerized Speech Lab for formant analysis of five Japanese vowels in maxillectomy patients

IntroductionSpeech impairment is a common complication after surgical resection of maxillary tumors. Maxillofacial prosthodontists play a critical role in restoring this function so that affected patients can enjoy better lives. For that purpose, several acoustic software packages have been used for speech evaluation, among which Computerized Speech Lab (CSL) and Praat are widely used in clinical and research contexts. Although CSL is a commercial product, Praat is freely available on the internet and can be used by patients and clinicians to practice several therapy goals. Therefore, this study aimed to determine if both software produced comparable results for the first two formant frequencies (F1 and F2) and their respective formant ranges obtained from the same voice samples from Japanese participants with maxillectomy defects.MethodsCSL was used as a reference to evaluate the accuracy of Praat with both the default and newly proposed adjusted settings. Thirty-seven participants were enrolled in this study for formant analysis of the five Japanese vowels (a/i/u/e/o) using CSL and Praat. Spearman’s rank correlation coefficient was used to judge the correlation between the analysis results of both programs regarding F1 and F2 and their respective formant ranges.ResultsAs the findings pointed out, highly positive correlations between both software were found for all acoustic features and all Praat settings.DiscussionThe strong correlations between the results of both CSL and Praat suggest that both programs may have similar decision strategies for atypical speech and for both sexes. This study highlights that the default settings in Praat can be used for formant analysis in maxillectomy patients with predictable accuracy. The proposed adjusted settings in Praat can yield more accurate results for formant analysis of atypical speech in maxillectomy cases when the examiner cannot precisely locate the formant frequencies using the default settings or confirm analysis results obtained using CSL.
