Abstract
Introduction

The increasing demand for attention to olfactory disorders, along with the persistent presence of sinonasal polyposis, has opened the need to treat these pathologies in very early stages.

Objectives

To demonstrate that incipient stages in sinonasal polyposis are detectable by olfactometry before radiological images, and that this detection is linked with a non-blocked area around the nasal meatus (where the olfactory cleft is located).

Methods

This study is based on data obtained from a sinonasal polyposis (degree 0 or 1) patient group (n=121) without allergies or asthma backgrounds. The patients underwent both fibroscopic and olfactometry explorations (first and fifth cranial nerve) and computed axial tomography (CT) assessment. The results were compared with the control group (n=120).

Results

Significant values (P<.05) of affectation were found in decreasing olfactory levels (olfactory and trigeminal nerves) in patients with degree 0 or 1 polyposis.

Conclusion

Olfactory disorders linked to a non-blocked area around the nasal meatus (degree 1 or 2 polyposis), together with sinonasal CT scans showing beginnings of ethmoidal inflammation, should be interpreted as incipient sinonasal polyposis.

Resumen
Introducción

La creciente demanda de atención sobre la patología del olfato, junto con la persistente presencia de la poliposis nasosinusal, ha abierto la necesidad de tratar dichas patologías a niveles muy tempranos.

Objetivos

Demostrar primero que los estadios incipientes de la poliposis nasosinusal son detectables por olfatometría antes que por imagen radiológica; segundo, tal detección se halla vinculada a la ausencia de ocupación del espacio «extrameatal» (donde se halla la hendidura olfativa).

Métodos

Estudio basado en los datos obtenidos a partir de un grupo (n=121) de pacientes con poliposis nasosinusal de grado 0 o grado 1, libres de alergias, tríada de ASA y asma, sometidos a estudio fibroendoscópico, olfatometría (par craneal I y V) y TAC nasosinusal, comparándose el resultado con un grupo control (n=120).

Resultados

Se confirmaron valores significativos (p<0,05) de afectación de los nervios olfatorio y trigémino, en los pacientes con grado 0 y grado 1 de poliposis.

Conclusiones

La presencia de alteraciones olfativas con ausencia de ocupación del espacio «extrameatal» (poliposis grado 1 o grado 2), acompañado de TAC nasosinusal con inicio de ocupación etmoidal, debería ser interpretada como inicio de poliposis nasosinusal.
