Monitoring the Outcome of Phonosurgery and Vocal Exercises with Established and New Diagnostic Tools

Table 2

Changes in vocal measures after treatment for all patients and separated for both intervention groups (logopedics/phonosurgery), both dysphonia groups (functional/organic), and all pathology classification subgroups according to Rosen and Murry [25].

Data expressed as mean differences of preoperative and postoperative values (upper line), with 95% confidence intervals (lower line, in brackets). VEM = vocal extent measure; DSI = dysphonia severity index; VHI-12 = voice handicap index; VHIs = self-perceived impairment of voice at the present time.
