Objective: This case comparison explored the relation between personality, perceived present control, and postoperative voice rest (as estimated by self-report and objective voice use) following surgery for benign vocal fold lesions.
Method: Two participants were included. Both participants were diagnosed with benign vocal fold pathology, underwent phonosurgery, and were assigned to either complete voice rest (CVR) or relative voice rest (RVR) postoperatively. During voice rest (VR), a visual analog scale (VAS) and a dosimeter (the Vocalog2) were used daily to estimate self-perceived and objective voice use, respectively. The participants also completed questionnaires on voice-related demographics, the Voice Handicap Index (VHI), Ten-Item Personality Inventory (TIPI), and Perceived Present Control (PPC). After 7 days of CVR or RVR, participants completed a postoperative questionnaire and a final VAS for overall voice use.
Results: A wide discrepancy was observed in one of two participant's subjective perception of voice use (using the VAS) versus objective dosimetry data wherein she reported significantly more voice use than was observed objectively. Differences in personality and PPC between the participants did not appear to affect their voice use following the VR protocols.
Conclusion: The amount of voice use in both VR protocols for these two participants suggests that personality and PPC did not affect their adherence to recommendations of VR. Patients may perceive their voice use differently across time, which might play a role in their adherence to voice rest recommendations: voice use measured as instances versus a unit of time (seconds).
