Abstract

Objective: To study the quality of life, jaw function and aesthetics in patients, at least 10

years after they have completed orthognathic treatment, in comparison with a control group.

Material and Methods: The sample was retrieved from a previous study by Abrahamsson et

al. The treatment group consisted of 94 consecutive patients (59 women and 35 men) with dentofacial deformities who were referred to Department of Oral Maxillofacial Surgery, Malmö University Hospital, Sweden for orthognathic surgery. The average age of the treatment group was 22.4 ±7.6 years. The control group consisted of 53 individuals (30 women and 23 men, with mean age 23.4 ± 7.3) and was recruited from the Department of Oral Diagnostics in Dentistry University in Malmö and at the Public Dental Service in Oxie. A questionnaire including Oral health impact profile (OHIP-14), Jaw functional limitation scale (JFLS-8) and Orofacial aesthetic scale (OAS-8) supplemented with two questions

directed to the treatment group was sent out to both the treatment and the control group.

Result: The response rate was 57% (n=54) in the treatment group and 53% (n=28) in the

control group. According to the result from OHIP-14 the quality of life was better in the treatment group in comparison with the control group. However, jaw function and

orofacial aesthetics were comparable between the groups according to the results from JFLS-8 and OAS-8. The majority of the patients in this study were very satisfied with the result of orthognathic surgery at 10 years follow-up.

Conclusion: Orthognathic treatment has been shown to be a successful treatment not only in

Sammanfattning

Syfte: Att studera livskvalitet, käkfunktion och estetik hos patienter som har genomgått

ortognat kirurgi, minst 10 år efter avslutad behandling, i jämförelse med en kontrollgrupp.

Material och Metod: Materialet har erhållits från en tidigare studie av Abrahamsson och

medarbetare. Behandlingsgruppen bestod av 94 konsekutiva patienter (59 kvinnor och 35 män) med käkanomalier som behandlats med ortognat kirurgi på Käkkirurgiska kliniken Universitetssjukhuset Malmö, Sverige. Medelåldern av behandlingsgruppen var 22.4 ±7.6 år. Kontrollgruppen bestod av 53 individer (30 kvinnor och 22 män, medelålder 23.4 ± 7.3 år) som rekryterades från avdelningen Oral Diagnostik på Malmö tandvårdshögskola och Oxie Folktandvård. De frågeformulär som skickades till grupperna bestod av Oral health impact profile (OHIP-14), Jaw function limitation scale (JFLS-8), Orofacial aesthetics scale (OAS-8)

och två tilläggsfrågor enbart för behandlingsgruppen.

Resultat: Svarsfrekvensen var 57 % (n=54) i behandlingsgruppen och 53 % (n=28) i

kontrollgruppen. Frågeformulären OHIP-14 visade att livskvaliteten var bättre i

behandlingsgruppen i jämförelse med kontrollgruppen. Däremot visade resultaten från JFLS-8 och OAS-8 att käkfunktion och estetik var jämförbara mellan grupperna. Majoriteten av patienterna i behandlingsgruppen var mycket nöjda med resultatet av ortognat kirurgi vid 10 års uppföljning.

Konklusion: Ortognat behandling har visats sig vara en lyckad behandling när det gäller
