    Symptoms and history
    are important.

    Individualized counselling and diagnostic management
    ensure an adequate treatment policy for each patient
    on an individual basis

  • Allergy


    25-30% of the population in western industrial
    societies suffer from allergies.

    Our long experience with allergy diseases enable us
    to provide you with dhe adequate diagnostic
    measures and treatment.

  • Nasal Airway Obstruction

    Nasal Airway Obstruction

    Nasal airway obstruction has a significant
    negative impact on patient's lives

    We have been involved with diseases of the nose and
    paranasal sinuses for almost 30 years and can therefore
    recommend the adequate therapeutic approach for diseases.

  • About the operation

    About the operation

    About 1/3 of the population
    suffers from snoring

    Our experience with different aspects of sleep medicine
    lasts more than 15 years. Our goals are making an exact diagnosis
    with screening and - if necessary - sleep laboratory evaluation and
    then advise you on legitimate therapeutic approaches.

  • Chronic rhinosinusitis

    Chronic rhinosinusitis

    Surgical procedures in the head are regarded
    as particularly dangerous by many patients.

    After thousands of pre-operative counselling sessions we know
    that operations in the head and neck area are considered as extremly
    dangerous by the patients. Therefore trust and safety are the top priorities of our work

  • Snoring


    About 1/3 of inflammatory sinus
    diseases become chronic.

    We have been involved in research and diagnostic management
    of nasal and paranasal sinus diseases for more than 25 years.
    This long experience enables us to give you adequate advice
    on how to treat those kinds of diseases.

How to find us

Nasal Airway Obstruction

There are many causes of nasal airway obstruction. In adults the most common causes are enlargement of the inferior turbinates or septal deviation or a combination of these two factors. Less common causes of obstruction are a foreign body in the nose (usually in children and unilateral), congenital malformations of the nose, polyps, tumors and injuries. In addition, some medications cause swelling of the turbinates, including some anti-hypertensive agents, anti-depressants, oral contraceptives and even chronic use of decongestant sprays or nose drops.

Impaired and thus inadequate nasal breathing-depending on the degree of severity-sooner or later leads to a variety of problems. Humans are obligatory “nasal breathers”; only the nose and its special mucosa can modify inhaled air so it can be maximally used by the lower airways. Even though many patients with marked nasal obstruction appear to have adjusted to the abnormal state, the long-term potential for negative health effects should not be underestimated.
Not matter what its cause, impaired nasal breathing can be coupled with blocked eustachian tubes, creating abnormal air balance in the middle ear which can lead to a an uncomfortable pressure sensation in the ears and hearing problems. In addition, those who must become “mouth breathers” usually complain of a dry mouth, as well as snoring with an abnormal sleep pattern and daytime drowsiness. Other complications of nasal airway obstruction include more frequent and recurrent infections, reduced energy levels, chronic fatigue, chronic rhinosinusitis and even lower airway disease (asthma, chronic bronchitis).

Many affected individuals fall into the trap of relying on over-the-counter nasal decongestants which they use for long periods of time trying to control their nasal swelling and obstruction. We strongly advise against this practice. The decongestants can permanently damage the mucosa. There also may be a “rebound phenomenon”-the drops or sprays may initially produce vessel constriction and thus cause shrinkage but as their effects wear off there is increased filling of the nasal blood vessels so that the swelling is more severe than prior to treatment. A vicious circle results-the patient using stronger and stronger medications more and more often, so that often dependence develops and the nasal airways are never open without using decongestants. The same patients may experience drying out of the mucosa with crusting and an increased likelihood of epistaxis (nose bleeds).
