Outcome Measures

Primary Outcomes (1)

  • Correlation between video-stroboscopic examination and histopathological results

    Correlation between video-stroboscopic examination and histopathological groups.

    baseline

Secondary Outcomes (1)

  • to correlate between SOX2 gene expression and histopathological finding

    baseline

Interventions

videolaryngoscopy and laryngostroboscoby will be performed .the latter will be pathological in case of highly reduced or abolished amplitudes of vocal fold vibration and if there is reduction of mucosal wave propagation.also direct microlaryngoscopy under general anathesia will be done and excesional biobsy will be taken followed by histopatholpgical examination .the histological finding will be catagorized into the following categories according to (WHO): squamous cell hyperplasia with non dysplasia,mild dysplasia,moderate dysplasia,sever dysplasia,carcinoma in situ and squamous cell carcinoma.

Study Population

one hundred patient with localized or diffuse vocal folds irregularites wiii be examined for primary diagnosis at the phoniatric unit of ENT department in Assiut university hospital.main symptom of all patients is dysphonia of varying degree and dauration from afew days to several months .

You may qualify if:

  • Age 18-70 years old males
  • Unilateral or bilateral localized and diffuse vocal fold irregularities.
  • Patients with white (leukoplakia) patches on one or both vocal folds
  • No previous microphonosurgery.
  • No previous history of radiotherapy .6.No impairment of the vocal fold mobility.

You may not qualify if:

  • Subject refusal.
  • Patients with large exophytic and/or ulcerated mass.
  • Vocal fold cysts or polyps, contact granulomas, or Reinke's edema
  • If there is a concern for rapid growth pattern, airway obstruction requiring urgent operative intervention
  • Vocal fold immobility
  • History of allergies and GERD.
  • Unfit for general anesthesia
