Methodology
A prospective study was conducted, including 16 consecutive patients
(after exclusion of one patient) undergoing septorhinoplasty by a single
surgeon (NA) and 32 controls. Patients were recruited from the senior
author’s University hospital and independent practices. All were primary
cases except one male patient, who had undergone two prior septoplasties
at a different centre and required rib graft. Control patients were
recruited from a general ENT clinic.
All participants completed the Standardized Cosmesis and Health Nasal
Outcomes Survey (SCHNOS) and Body Dysmorphic Disorder Questionnaire
(BDDQ) pre-operatively and again post-operatively (figure 1). Follow-up
range was 9-24 months. Patients who did not attend follow-up were
contacted by telephone to complete the questionnaires. One patient was
not contactable post-operatively and had to be excluded from the
analysis.
SCHNOS is a validated questionnaire that assesses functional and
aesthetic patient-reported outcomes following rhinoplasty . Each
question is scored on a Likert scale of between zero and five (zero
being no problem, and five being an extreme problem).
The SCHNOS produces two scores; a nasal obstruction score (SCHNOS-O) and
a nasal cosmesis score (SCHNOS-C). The SCHNOS-O is calculated as a sum
of scores of items 1–4 divided by 20 and multiplied by 100. The
SCHNOS-C score is calculated as a sum of scores of items 5–10 divided
by 30 and multiplied by 100 (figure 1).
