KTP 532 Laser Assisted Surgery for Oral Cavity Malignancy-A Retrospective Study.

Abstract

To determine the effectiveness of KTP 532 in surgically treating early and early advanced oral malignancy with no surgical reconstruction of primary site. It is a retrospective study of 67 cases operated between 2000 to 2013 including T1, T2 and Early T3 cases, approved by ethical committee. All the cases underwent Laser assisted excision of tumour with or without Neck Dissection or Adjuvant Radiotherapy. Age of the cases varied from 20 to 80 years with mean age of 49 years. 47 cases were males and 20 were females. 26 cases in the study had neck nodes clinically whereas 41 cases had N0 status. Neck dissection was done (SOND or MRND) in 61 cases. In 6 cases (N0) no neck dissection was done. 61 cases had no loco-regional residual disease on their last follow up. Six cases had loco-regional recurrence within 6 months and salvage surgery was done. The overall mean survival was 81 months (92, 82 and 71 months in Stage I, II,III respectively). 3 year disease free survival rate was 91% as calculated using Kaplan- Meier Scale. In all these cases tumour was excised with KTP 532 laser and no reconstruction was done. Wound was allowed to heal with secondary intention. Laser assisted excision of oral malignancy is an alternative to conventional treatment with more precision, less morbidity, shorter hospital stay and better functional outcomes.
