Study Description
Brief Summary
The purpose of the study was to determine, whether patients with recurrent respiratory papillomatosis (RRP) suffer from extra oesophageal reflux more often than patients with laryngeal cyst (control group).

Detailed Description
Recurrent respiratory papillomatosis (RRP) is a chronic viral disease, which affects children and adults as well. It is characterised by grow of squamous cell tumours on mucosa of aerodigestive tract, with predilection for the larynx. The disease is caused by the human papillomavirus (HPV). However, in contrast to the low incidence of RRP, HPV prevalence is common. It is indicated that other factors may contribute to the pathogenesis of RRP. One such factor might be extraesophageal reflux (EER). We investigated whether patients with RRP suffer more often from EER.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: Recurrent respiratory papillomatosis Patients with recurrent respiratory papillomatosis (RRP) - surgical collection of histology specimen from the vocal cords and rear laryngeal commissure, performance of immunohistochemical analysis - proof of pepsin, HPV 6 and 11, herpes simplex virus (HSV) type 2, chlamydia trachomasis, and assessment of the dysplasia. |
Procedure: Surgical collection of histology specimen
Collection of a histology specimen from the vocal cords and rear laryngeal commissure
Procedure: Performance of immunohistochemical analysis
Immunohistochemical analysis - presence of pepsin, HPV 6 and 11, HSV 2 and chlamydia trachomasis

| Active Comparator: Laryngeal cyst - control group Patients with laryngeal cyst - surgical collection of a histology specimen from the vocal cords and rear laryngeal commissure, performance of immunohistochemical analysis - proof of pepsin and HPV 6 and 11, herpes simplex virus (HSV) type 2 and chlamydia trachomasis. |

Outcome Measures
Primary Outcome Measures
- Occurrence of EER (percentage) [36 months]
The occurrence of extra oesophageal reflux will be assessed in both study groups.
Secondary Outcome Measures
- Presence of pepsin [36 months]
The presence of pepsin (yes-no) will be assessed in both study groups.
