This gentle, minimally invasive procedure serves to resolve problems of ventilation and drainage in the sinuses and generally involves little bleeding and no pain. It is particularly helpful for chronic sinus inflammation (sinusitis), which can often be associated with obstructions to nasal breathing, headaches, increased mucus formation and frequent bronchitis, as well as bronchial asthma (sinubronchial syndrome). The intervention is an example of so-called “keyhole surgery”, meaning an endoscope is passed through the nasal opening and minute instruments used to rectify the constrictions in the sinuses so that the body can cure itself. As part of the process, a light nasal tamponade or breathing tube may be used for one night. Post-operatively, the improved ventilation of the sinuses quickly becomes noticeable through improved nasal breathing. Following the surgery, it is recommended that patients make use of nasal ointments and saltwater rinses to support the healing of the mucous membranes in the nose.
If the patient has considerable polyp formations in the sinus system then relapse prevention is recommended post-surgery alongside the operational restoration of the nasal cavities by means of a special cortisone treatment programme.
