title: Excision biopsy of tongue lesions by diode laser.
abstract: OBJECTIVE
  The aim of this study was to evaluate the diode laser in excision biopsy of superficial proliferative tongue lesions under local anesthesia.
  
  
  BACKGROUND
  Most mobile tongue lesions present as surface projections and have similar clinical features. They are usually excised for diagnostic purposes using conventional surgery or electrosurgery. The diode laser has proven itself useful in different oral surgeries.
  
  
  METHODS
  We report the results of a prospective pilot study where contact diode laser was used in excision biopsy of six mobile tongue lesions. All excised tissues were pathologically examined. To assess post-operative pain, patients were asked to correlate it to an 11-point Visual Analogue Scale (VAS); patients were also asked to assess their impression of alteration in tongue size on a 4-point scale. Healing, functional results, and recurrence rate were assessed.
  
  
  RESULTS
  All interventions were uneventful and done at the same out-patient setting. All lesions were benign. Healing occurred by secondary intention in the six cases with no residual ulceration. Postoperative pain was mild in four cases, while two cases suffered from moderate pain. Post-operative impression of tongue swelling occurred in all cases. The mild impression disappeared by the end of the first week and the moderate one by the end of the second week. No recurrence was observed over a mean follow-up period of 15 months.
  
  
  CONCLUSIONS
  The diode 980-nm laser is optimal for excision biopsy of superficial and benign proliferative lesions of the mobile tongue.
