P147 Analysis of Formant Frequencies in Patients With Oral or Oropharyngeal Cancers Treated by Glossectomy

P147 Analysis of Formant Frequencies in Patients With Oral or Oropharyngeal Cancers Treated by... Objective: To compare voice quality as defined by formant analysis using sustained vowel in patients who had undergone a partial glossectomy with a group of normal subjects. Design: Single-center, cross-sectional cohort study. Setting: Adult tertiary oncology referral unit. Patients: Twenty-six patients (19 male) who underwent partial glossectomy and 31 healthy volunteers (18 male) participated in our study. Intervention: Group comparisons using the first 3 formant frequencies (F1, F2, and F3) using linear predictive coding (Laryngograph Ltd, London, England) were performed. Main Outcome Measures: The existence of any significant difference of F1, F2, and F3 between the 2 groups using the sustained vowel /i/ and the effects of other factors, namely, age, first presentation vs recurrence, site (oral cavity or oropharynx), subsite (anterior two thirds of the tongue or tongue base), stage, irradiation, complication, and neck dissection was determined. Results: Formant frequencies F1, F2, and F3 were normally distributed. The F1 and F2 frequencies were significantly different in normal male vs female subjects. The F1, F2, and F3 frequencies were no different statistically between male and female patients who underwent glossectomy. Comparison of only women showed significant differences between healthy subjects and patients in F2 and F3 but none in F1. This was the opposite in men, for whom F1 was significantly different. Age, tumor presentation, site, subsite, irradiation, and neck dissection showed no significant difference. Postoperative complications significantly affected the F1 formant frequency. Conclusions: This study found that the formant values in patients following a partial glossectomy were altered significantly compared with the control subjects. Only sex and complications and not the age, site, subsite, irradiation, and neck dissection were seen to influence the formant scores. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Otolaryngology - Head & Neck Surgery American Medical Association
