[Argon plasma coagulation and topically applied estriol. Long-term results in the treatment of hereditary hemorrhagic telangiectasia of the nasal mucosa].

BACKGROUND AND OBJECTIVE: Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant fibrovascular dysplasia with the main symptom of recurrent epistaxis. At present, only limited data are available on long-term results in the treatment of epistaxis. A part from the surgical treatment of the bleeding telangiectasia with argon plasma, an additional postoperative long-term treatment with estriol nose-ointment was performed and the results were analysed.

PATIENTS AND METHODS: 69 patients with HHT were treated with APC and estriol nose ointment. 43 patients could be examined over a follow-up period of more than 20 months. The bleeding frequency and intensity as well as the patient's satisfaction with the treatment result were evaluated and the serum estriol level determined.

RESULTS: After more than 20 months, the bleeding frequency and intensity were reduced in 95% of the patients compared to their preoperative findings. Under the influence of estriol, former berry-like telangiectasias became flatter and more even. Neither systemic side effects under topically applied estriol nor a relevant increase of serum estriol levels were observed.

CONCLUSION: The combined treatment regimen with APC and topically applied estriol provides a new treatment concept of epistaxis in HHT.
