title: Prosthetic rehabilitation of patients with maxillary defects in a nigerian tertiary hospital.
abstract: BACKGROUND
  Maxillary defects are managed by prosthodontic rehabilitation using obturators. This rehabilitation goes through various stages, which invariably affects the quality-of-life of the patients.
  
  
  OBJECTIVE
  This study aims to analyze the types and design of obturators used in the rehabilitation of maxillary defects at a tertiary health institution in Nigeria.
  
  
  METHODS
  This is a retrospective study of all patients with maxillary defects treated at a tertiary institution between the period of October 2010 and May 2013. The data of interest collected from the patient's register and case notes include age, gender, type of defects, design of obturators and conditions for which treatment was offered. The collected data were analyzed using Statistical Package for Social Sciences version 16.0 (Chicago, Illinois, 2010) and result presented in frequencies and tables.
  
  
  RESULTS
  A total of 19 case notes were retrieved. The age range was 5-73 years with the mean age of 46.37 ± 19.02 and peak age incidence at 41-60 years. The male: female ratio was 1:1.4. Surgical defects were the most common type of maxillary defects seen; accounting for 89.5% (17/19) of the cases, which were mostly associated with malignant tumors. Immediate surgical obturators were provided for 63.2% (12/19) of the subjects. Majority 70.6% (12/17) of those with surgical defects received immediate surgical obturators while all those with congenital defect were given feeding plate. There was a statistically significant association between the type of maxillary defect and type of obturator provided (P < 0.01).
  
  
  CONCLUSIONS
  The results of this study suggest that majority of the obturators fabricated for patients with maxillary defect at the Tertiary health institution in Nigeria were immediate surgical obturators. Pre-surgical patient education and follow-up care is advocated.
