Abstract

OBJECTIVES:

To assess olfactory outcomes in patients undergoing septorhinoplasty surgery in our unit.

DESIGN:

Prospective cohort study.

SETTING:

The Royal National Throat Nose and Ear Hospital, London.

PARTICIPANTS:

Forty-three patients undergoing functional septorhinoplasty (Males = 26; mean age = 34.1 ± 12.2) were recruited into the study.

MAIN OUTCOME MEASURES:

The primary outcome of olfactory function was assessed using 'Sniffin sticks'. Our secondary outcomes were assessment of patient quality of life using the disease specific Sino-nasal Outcome Test-23 questionnaire (SNOT-23) and a visual analogue scale for sense of smell. These measures were repeated at 12 weeks post operatively.

RESULTS:

There was a significant change in the Sniffin' sticks score post-operatively (8.3 versus 9.6; P < 0.001). The SNOT-23 score also showed a significant improvement post-operatively (53.5 versus 40.4; P < 0.001). A significant improvement was not found in the smell/taste question (question 21) of the SNOT-23 questionnaire as well as the visual analogue scale for sense of smell. A difference in olfactory outcome was not found between open versus closed approaches, primary versus revision surgery and traumatic versus non traumatic cases.

CONCLUSIONS:

The results show a measured significant improvement in olfaction following functional Septorhinoplasty but not a subjective improvement in the patients perception of their sense of smell and hence not a clinically significant difference. The reasons for the measured improvement are not clear and are likely to be multifactorial.
