Which one of the following is true statement regarding Singer's Nodule?: (A) It occurs at the junction of anterior 1/3rd & posterior 2/3rd, (B) Most common symptom is pain, (C) Laser therapy is the treatment of choice, (D) Requires excision of nodule as it is potentially malignant
Answer is A. (A) It occurs at the junction of anterior 1/3rd & posterior 2/3rd[?]Vocal Nodules or Singer's or Screamer's Nodes:Seen symmetrically on free edge of vocal cord, at junction of anterior 1/3rd, posterior 2/3rd, (area of maximum vibration of vocal cord & causes maximum trauma).Vocal nodule size is pin-head to half a pea.Aetiology: Vocal trauma occurs, when person speaks in unnatural low tones for prolonged periods or at high intensities.Singer's nodes mostly affect teachers, actors, vendors or pop singers & also seen in school going children.Pathology: Trauma to vocal cord in form of vocal abuse or misuse causes oedema & haemorrhage in submucosal space & undergoes hyalinisation and fibrosis.Epithelium undergoes hyperplasia and forms a nodule.In early stages, vocal nodules appear soft, reddish & oedematous swellings.In later stages, vocal nodules appear greyish or white in colour.Clinical Features: Hoarseness, vocal fatigue & pain in the neck on prolonged phonation.Treatment of Early Cases: Conservatively by educating proper use of voice.Treatment for large nodules or nodules of long-standing in adults surgery is required by excision with precision under operating microscopic.Prevention of recurrence: Speech therapy & re-education in voice production.MOST COMMON SITE OF LARYNGEAL LESIONSLaryngeal LesionCommonest site*.
