Definitions

  • Dysphonia:  "Altered vocal quality, pitch, loudness, or vocal effort that imparis communication and/or quality of life" as defined by the AAO -HSN Clinical Practice Guideline Update (Stachler et al 2018)
  • Hoarseness: "A symptom of altered voice quality rerported by patients" (Stachler 2018)
  • Vocal Nodules: "Benign masses located in the lamina propria typically at the midpoint of the membranous vocal folds" (Verdolini 2006)
  • Vocal Fold Hemorrhage the rupture of a submucosal blood vessel of the vocal fold usually associated with internal or external laryngeal trauma and may be associated with impaired coagulation (Lennon, 2013).
  • Vocal range: spectrum of pitches the singer can produce
  • Register: "distinct regions of vocal quality that can be mainteained over some ranges of pitch and loudness" (Titze 1988)
  • Tessitura: the vocal range produced in a comfortable manner   --   Extension: total range that can be vocalized with effort
  • Timber: "the color or tone of the sound" (Rubin and Codino 2019) usually sounds best in the singer's tessitura
  • Passagio: the transition between registers - a sensitive area for vibratory impairment as one 'navigates the passagio"
  • "Straw Phonation" - a form of semioccluded vocal tract exercises are "characterized by a reduction in the cross-sectional area of the distal part of the vocal tract while voicing"  (Kang 2020) see: Teaching Vocal Heath as Music Educator

Background

As per Rubin and Codino (2019) - caring for the professional singer requires a "deeper understanding of the demands, vocabulary, psyche, and economics of the professional singer to provide optimal care". 

Management

  • Voice Rest - Vocal Conservation as a Management Strategy (Non-operative and Post-op)
  • Steroids Side Effects Systemic Corticosteroid Therapy Adverse Effects (balance short term benefit with long term sequelae)
    • Gehling et al (2014) through survey of 135 Broadway singers identified 32% had used steroids to treat voice problems
    • Estes et al (2021) in evaluating management of vocal performers presenting with hoarseness and identified with vocal fold edema on videostroboscopy
      • all counselled about voice rest and oral steroids
      • those that chose steroids were offered enrollment in study
      • treatment with oral glucocorticoids (6-day methylprednisolone taper beginning with 24 mg and decreasing by 4 mg daily)
        • medrol dose pak = 
      • "potential problems identified with steroids: repeated short term use may be associated with effects similar to those of long-term use"
        • osteopenia, hyperglycemia, cataracts, weight gain, cardiac disease
        • 'even a singel methylprednisolone taper pack appears to slightly but increase the risk of osteonecrosis" (citing Dilisio 2014)
        • laryngeal thrush (candida) developed in 5.5% of patients in their study treated with the 6-d steroid course
      • Conclusions from this study evaluating singers with acute vocal fold edema
        • "careful examination of the vocal folds by means of laryngoscopy, prefereably videostroboscopy, is mandatory" and 'should be repeated if symptoms do not improve as expected'
        • recommended treatment is voice rest and treatment of underlying cause
        • "oral steroids may be used to speed the reolution of acute inflammatory changes, with a small possiblity of vocal fold hemorrhage and/or thrush."
        • "repeated need for steroids raises suspicion of overlooked pathology and makes re-evalautionf the larynx advisable"
        • 'serial steroid use should never substitue for a thorough laryngeal evaluation"
    • Estes et al (2022) in a followup article reported on 55 vocal performers treated wtih 6-day methylprednisolone taper
      • prospective evaluation employing the EASE (Evaluation fo the Ability to Sing Easily) questionnaire
      • "significant improvement demonstrated in several facets of performers' sef-perception of function"
      • "appropriate use of these medications appears both safe and effective" -
        • with their study serving to "help debunk myths about singing while on steroids".
        • emphasizing 'steroids be prescirbed carefully, and only following thorough laryngeal examination"
  • ​​​Vocal Fold Hemorrhage, Vocal Cord Bleed, Vocal Varix, Telangiectasia
  • Voice Team: Laryngologist / Speech Pathologist / Singing Teacher or Coach 
  • Warm up
  • Humidification
