Correlation Between Headaches and Septum and Nasal Mucosa Contact
Correlation Between Headaches and Septum and Nasal Mucosa Contact
Headache is the most common complaint to neurologists. In the 80´s and 90's few papers, with
 limited number of patients, have proposed the association between nasal septum contact and
 headache. The International Classification of Headaches Disorders proposed specific
 diagnostic criteria for this entity.

 With the major use of CT scans, the contact between nasal mucosa and septum is daily observed
 in many patients without complaint of headache.

 The purpose of this study is to determine if there is any correlation between nasal and
 septum mucosa contact and the prevalence of headache. The investigators hypothesized that no
 correlation will be found using CT scans in a large series of patients.
Every patient older than 18 years old whom underwent sinuses or facial computed tomography
 will be asked to answer a questionnaire, where he will be able to describe his headache
 features (if present) . This information will be correlated with patient images findings,
 which are going to be evaluated by head and neck radiologists blinded for clinical
 information. Logistic regression model will be used to verify this association; the presence
 of sinusitis and fever will used be as covariates.
Inclusion Criteria:

 -  All patients older than 18 years whom underwent sinuses or facial tomography.

 Exclusion Criteria:

 -  Patients with clinical history of trauma
