Anatomical variations of the paranasal sinuses in Polynesian and New Zealand European computerized tomography scans.
OBJECTIVE
This study was designed to compare the incidence of anatomical variations displayed on computerized tomography scans of individuals that identify as Polynesian or New Zealand Europeans.


METHODS
A retrospective analysis of computerized tomography of the paranasal sinuses. All scans were examined for a number of anatomical variations and the prevalence directly compared according to ethnic group.


METHODS
All scans were performed at a tertiary referral center (Dunedin Public Hospital).


METHODS
Participants underwent computerized tomography of the paranasal sinuses for various indications. Ethnicity was determined from the electronic hospital record.


RESULTS
There was no significant difference in the prevalence of anatomical variations between Polynesians and New Zealand Europeans. Our study results are comparable with other studies of Caucasian paranasal sinus anatomy.


CONCLUSIONS
When performing endoscopic sinus surgery on those with Polynesian ethnicity, there are no specific anatomical variations to take into account.
