Abstract
Objectives: Acquired skull deformities are common and most likely treated surgically by cranioplasty. Since data on patient aesthetic outcome after cranioplasty are rare in literature, we aimed to assess patient satisfaction after polymethyl-methacrylate (PMMA) cranioplasty in this study using a questionnaire.Methods: A patient questionnaire was developed to evaluate the grade of satisfaction after surgery. After approval by the institutional ethical review board, we were allowed to send to all 115 patients, who received a cranioplasty from 2001 to 2008 at the University Hospital of Zurich, our questionnaire once to retrospectively analyze the patient response together with the patient hospital records.Results: Out of 115 patients, 36 patients were lost to follow-up and our questionnaire was sent out once to 79 patients. Sixty-three of 79 patients replied to the questionnaire (79·7%) and 16 did not reply. Seventeen declined to participate in this study and out of the remaining 46 patients (58·2%, 18 women, mean age 54 years, range 20–83 years), who agreed to participate in this study, 22 (47·8%) judged their cranioplasty to be aesthetically ‘excellent’, 16 (34·8%) ‘favorable’ and 4 (8·7%) ‘poor’. Another four patients (8·7%) were not satisfied, asking for a surgical revision. Patient age and gender was not related to the assessment of the aesthetic result. A higher satisfaction grade was found in patients with primary PMMA cranioplasty compared to PMMA cranioplasty implanted during a second surgery (Fisher’s exact test, P = 0·031). A dent was strongly associated with absence of satisfaction (P<0·01, Fisher’s exact test).Conclusion: Our questionnaire was suitable to assess patient satisfaction after cranioplasty. Localization of cranioplasty showed to be an important factor of aesthetic outcome, especially in the fronto-temporal region where a carefully planned reconstruction should be performed to guarantee an excellent grade of satisfaction after surgery.
