“…41 The application of mitomycin C or cryotherapy intraoperatively after resection of anterior commissure tumors may also reduce granuloma and web formation. 42,43 No study has specifically evaluated voice outcomes in patients requiring a "secondlook" procedure (repeat TLM to ascertain margin status), but the study by Stone and colleagues 33 found a correlation between the number of TLM procedures and worse acoustic voice results. Repeat TLM resection may indeed increase the ultimate amount of tissue resected at the glottis and produce further scar tissue.…”

“…Although SL patients have been subjected to acoustic analyses (5,17,18), neither the sCPP nor the CPP of such patients have been studied (to the best of our knowledge). Stone et al (10) found that the sCPPs of patients who had undergone transoral laser microsurgery were generally low; sCPP does not depend on Fo, which is difficult to measure in severely dysphonic patients (19). The Fo, which is the principal contributor to voice perception, differed significantly between SL and control patients.…”

“…The CPP integrates waveform measures with periodicity perturbations in amplitude, frequency, and/ or noise (9). Although vocal quality is of major concern to laryngectomy surgeons, only a few studies have analyzed sCPP after partial laryngectomies (10). We analyzed sCPPs following SL.…”

The aim of this study is to evaluate smoothed cepstral peak point and laryngostrobosopic results in patients who underwent supraglottic laryngectomy. Method: Ten patients who underwent transcervical supraglottic laryngectomy with bilateral modified radical neck dissection, and who completed at least 12 months of follow-up, were included. All patients underwent laryngostroboscopic evaluation at study commencement; glottal closure and mucosal wave pattern were examined. Voice records were taken at fundamental frequency and smoothed cepstral peak point were analysed. Voice handicap index-10 was requested to be completed. Ten healthy individual constituted control group. Results were compared. Results: The mean smoothed cepstral peak points were 1.53-5.91 in the supraglottic laryngectomy group and 4.6-6.06 in controls, a significant difference. The fundamental frequency ranged from 174.49 to 197.25 Hz in the supraglottic laryngectomy group and from 118.57 to 197.61 Hz in the control group, also a significant difference. Laryngostroboscopic evaluation revealed no significant between-group differences in closure, but the mucosal waves differed significantly. Voice handicap index was significantly lower in supraglottic laryngectomy patients. Conclusion: Supraglottic laryngectomy reduces smoothed cepstral peak point and affects the mucosal wave, reducing voice quality.

“…18 The CPP and CPPS have also been used to evaluate outcome after voice therapy 20 and laryngeal surgeries. 21,22 However, there is consistent evidence that CPP may be sensitive to individual vocal tasks, intensity, 14 and vocal tract configuration, in which different vowels have demonstrated different CPPS values, 14 and a nasal sentence has a high CPP. 23 Conversely, lower CPP values have been observed in patients with velopharyngeal insufficiency (VPI).…”

Objectives/Hypothesis Cepstral peak prominence (CPP) has been reported as a reliable measure of dysphonia and a preferred alternative to harmonics‐to‐noise ratio (HNR). However, CPP has been observed to be sensitive to articulatory variation and vocal intensity. The aim of this study was to examine the impact of nasalance on CPP and HNR of voice signals. It was hypothesized that increased nasalance would be associated with decreased CPP. Study Design Within‐subject correlation design. Methods Thirty vocally healthy female participants were recorded reading and producing a vowel in alternation with a nasal consonant while wearing a nasometer for calculation of nasalance. Recorded vowel, nasalized, and nasal segments of speech were used to calculate CPP using Analysis of Dysphonia in Speech and Voice software, and HNR and vocal intensity using Praat software. Results Significant main effects of conditions were observed for CPP. CPP values decreased significantly when phonation changed from vowel to nasalized vowel and to nasal. There was correlation between CPP and nasalance and between CPP and intensity. HNR was slightly higher in the nasal condition than in vowel. There was a weak correlation between HNR and nasalance. No correlation was found between HNR and intensity. Conclusions CPP is sensitive to changes in vocal tract configuration caused by nasalization as well as intensity, whereas HNR is not. Therefore, CPP may reflect the periodicity in source signal or the filtering effects of vocal tract. Further research is needed to clarify the application and interpretation of CPP in clinical practice. Level of Evidence 4 Laryngoscope, 129:E299–E304, 2019
