About this study

Official title: Thulium Contact Laser in the Treatment of Tumorous and Non-tumorous Laryngotracheal Stenosis

The purpose of the study is to compare results of the treatment of tumorous and non-tumorous laryngotracheal stenosis using thulium contact laser versus carbon dioxide laser used in the past.

Read the detailed description

Laryngotracheal stenosis is a serious disease significantly worsening the quality of life. Impaired breathing often leads to tracheotomy, deterioration of the voice leads to communication problems with others and swallowing problems are often present, as well The main causes of laryngotracheal stenosis are post intubation and post tracheostomy conditions, inflammatory process (often autoimmune), tumors (mainly squamous cell carcinoma and chondroma) and trauma. Within the last years there is substantial shift in the treatment strategy from open surgery to endoscopic techniques. However, surgical treatment is often difficult due to demanding exposure of tumor and problematic margins control.

In recent years there has been a development of particular techniques of endoscopic resection of tumors and non-malignant laryngeal glottic and subglottic stenosis using a carbon dioxide (CO2) laser with promising improvement of treatment results.

However, CO2 laser has some limitations, particularly in the treatment of tumors spreading into anterior commissure, because CO2 laser beam cannot get "around the corner". Moreover, subglottic area is also difficult to be reached by CO2 laser beam. Therefore, contact laser with adjustable manipulators with possibility to bend tip of manipulator according to the actual need seems to be of some advantage.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of carcinoma recurrence in the patient population

    The percentage of carcinoma recurrence will be monitored and evaluated within the study subjects.

    Measured: 36 months

Secondary outcomes (3)
  1. Percentage of decannulation in the patient population

    The percentage of decannulation will be monitored among the study subjects.

    Measured: 36 months

  2. Voice quality (Voice Handicap Index)

    Voice quality will be assessed according to the Voice Handicap Index, which is an acknowledged measurement tool providing precise evaluation of the condition.

    Measured: 36 months

  3. Swallowing (SWAL-QOL) questionnaire

    Swallowing will be assessed in the study group using the SWAL-QOL measurement tool (questionnaire) providing precise evaluation of the condition.

    Measured: 36 months
