Abstract
Functional nasal surgery is frequently performed for sinonasal diseases not responding to medical treatment. Although surgery mostly turns out to be successful in such cases, a potential side effect of manipulating the nasal mucous membrane is impairment of intranasal trigeminal function. Not well known by specialists and clinically scarcely explored, this function provides sensory information from the nasal mucosa. It is responsible for the afferent part of protective nasal reflexes such as sneezing and coughing, but also provides the feeling of nasal airflow (1). Recent work suggests that patients with low intranasal trigeminal function are more prone to suffer from nasal obstruction and may be less satisfied with functional surgery (2-6). It has been suggested that intranasal trigeminal function decreases with mucosal changes, such as chronic inflammation and improves again once the inflammation has been treated (3). However, the influence of functional nasal surgery (i.e. surgery aimed at the improvement of nasal function) with consecutive mucosal micro-injuries on intranasal trigeminal function is not yet fully clear (2-4).
