UNASSIGNED: In the management of laryngeal pre-cancerous lesions such as @entity1141 or @entity2735 ( @entity2735 ), it is important that lesion regression occur without any complications. As a minimally invasive treatment option, photocoagulation therapy using angiolytic lasers has been attracting attention. Therapeutic effects have been reported for this type of treatment, however, vocal function after treatment has not been well discussed. In this retrospective case series, we examined the therapeutic effects of photocoagulation therapy on @entity7552 and the impact on vocal function. Twenty-four @entity1 with @entity7552 or @entity2735 were treated with photocoagulation therapy using angiolytic lasers. Two @entity1 were treated under general anesthesia, the remaining 22 @entity1 were treated with topical anesthesia. Before and after treatment the extent of the lesion and vocal function was evaluated by endoscopic examination and acoustic and aerodynamic analyses, respectively. More than 50  % disease regression was observed in 20 of 24 @entity1 . Acoustic and aerodynamic analyses revealed improvement in pitch perturbation quotient with no impairment in other parameters. Photocoagulation therapy using angiolytic lasers has proven to be feasible and safe for the treatment of @entity7552 .
