Abstract:
BACKGROUND AND OBJECTIVES: Reinke's edema is defined as swelling confined to the space underneath the epithelial layer known as Reinke's space. Patients suffering from Reinke's edema are known to have abnormally low fundamental frequency and high subglottic pressure. We compared the preoperative and postoperative voice results of Reinke's edema to evaluate quantitative changes of vocal function. MATERIALS AND METHODS: The voice analyses of 15 patients, who were diagnosed with Reinke's edema from 1997 January to 1998 September in Seoul National University Hospital, and 15 normal controls were undertaken with Multi-dimensional voice program (MDVP) and Aerophone II of Kay system. Eight preoperative patients, 13 postoperative patients, and 6 preoperative and postoperative patients were analyzed with respect to fundamental frequency (F0), pitch perturbation quotient (PPQ), amplitude perturbation quotient (APQ), noise-to-harmonic ratio (NHR), subglottic pressure (Psg), mean vocal efficiency, mean flow rate (MFR), maximum phonation time (MPT), and contact quotient (CQ). Using videostrobokymography, vibratory patterns of vocal folds were analyzed. RESULTS: The fundamental frequency was lower than the normal preoperative and postoperative values. The PPQ, APQ, and NHR were decreased to the normal value after operation. The subglottic pressure, although elevated preoperatively and decreased postoperatively, remained high. The mean vocal efficiency was increased to average value of normal controls after operation. The MFR, MPT, and CQ were not correlated with the course of Reinke's edema. The vocal folds vibration returned to regular pattern after operation on videostrobokymography. CONCLUSION: The fundamental frequency and subglottic pressure are not normalized after operation, and the PPQ, APQ, and NHR are good parameters of postoperative voice results. The voice therapy might help to correct the vocal habit of voice abuse and prevent recurrence after operation.
