Description/Abstract

Concha bullosa is hypertrophy of the middle nasal concha attributable to its pneumatisation. It is considered to
be themost common anatomical variant of the ostiomeatal complex, but it has been little studied in skeletal populations.
It is uncertain whether the prevalence of concha bullosa varies in different world populations. Some have
suggested that it predisposes to sinusitis, but this is controversial. The aim of the current work is to assess the
prevalence of concha bullosa in a pre-modern population and to investigate whether it is associated with maxillary
sinusitis. Results showed that concha bullosa was present in 17 out of 45 individuals, a prevalence of 38%.
There was no evidence of an association with sinusitis. This adds to a growing body of evidence that calls into
question concha bullosa as a significant risk factor for sinus disease.
