“…Open top design of obturator was preferred. 15 , 16 Extension along posterior and lateral margins of defect was emphasized to enhance retention, stability, and support. Vertical extension in the postero-medial region of the defect was carefully designed to minimize leakage.…”

PURPOSETo assess function by identifying changes in swallowing and masticatory performance in maxillary obturator prosthesis wearers.MATERIALS AND METHODSSixty subjects were recruited for the study, of which 20 were obturator wearers, 20 were completely dentulous and 20 had removable partial/complete dentures with similar Eichner's Index. Swallowing ability was evaluated with and without obturator using the "Water Drinking Test"; Masticatory performance was evaluated with the Sieve test; and maximum occlusal force was recorded with the help of a digital bite sensor. The data was analyzed using the Statistical Package for Social Science version 15.0 with a confidence level at 95%.RESULTSProfile, behavior of drinking and time taken to drink were significantly improved (P<.001) in subjects after wearing obturator. Masticatory performance was not significantly different (P=.252) in obturator wearer when compared with dentulous or removable partial/complete denture wearer, but significantly (P<.001) high inter group difference in maximum occlusal force existed. Correlation between masticatory performance and maximum occlusal force was not significant (P=.124).CONCLUSIONSwallowing ability was significantly improved after wearing obturator but masticatory performance was not significantly different from those having similar occlusal support zone in their dentition.

“…[ 2 3 ] The resulting deficiency on the maxilla on account of treatment may give rise to communication between the oral and nasal cavities and the maxillary antrum. [ 4 ] This may bring about difficulties in mastication and result in hypernasal speech, fluid leakage, and various degrees of esthetic concerns, which need to be addressed surgically or by prosthetic rehabilitation. [ 4 ] The change in physiologic processes with varying degrees of physical, functional, and cosmetic issues may lead to a reduction in the quality of life (QOL) in an otherwise previously healthy individual.…”

Maxillectomy and quality of life: Experience from a Nigerian tertiary institution

et al. 2018

Introduction:Maxillectomy is a surgical procedure for managing tumors affecting the maxilla; the goal of maxillectomy however should not be limited to tumor extirpation but should include restoration of oronasal function and facial contours, as failure to do these may give rise to psychosocial and functional challenges. This study aimed to appraise the pattern of maxillectomies, challenges of management, and quality of life (QOL) of a proportion of the study population.Materials and Methods:This was a cross-sectional study carried out at the Department of Oral and Maxillofacial Surgery, University College Hospital, Ibadan. Patients’ case files from year 2000 to 2016 were retrieved and reviewed. Data extracted for analysis included age, gender, site of lesion, and histologic diagnosis; lesions were grouped as benign or malignant. Contacts were made with patients or their next of kin for a clinic review appointment where QOL was assessed with the University of Washington Quality of Life version 4 Questionnaire. Data were analyzed and result presented as means and frequencies.Results:Out of the 78 cases of maxillectomy recorded in the department within the study period, records were available and adequate in 67 cases. There were 37 (55.2%) females with a mean age of 35.88 ± 14.9 years. Swelling was the most common reason for presentation (63, 94%). The mean period between onset of disease and presentation for treatment was 3.66 ± 3.35 years. Distribution of lesions was benign 35 (52.2%) and malignant 32 (47.8%). Hemi-maxillectomy was the commonest surgical procedure (23, 34.8%). While majority had some prosthetic rehabilitation, 31 participants (48.5%) obtained no prosthesis. Eight participants gave scores of ≥75% when comparing their present health-related QOL (HR-QOL) with a month before surgery; the overall QOL was ≥60%. However, HR-QOL and overall QOL in the last 7 days before assessment were rated as good in 55.6% and 66.7%, respectively. Chewing was the most important domain to participants.Conclusion:The pattern of presentation and indications for maxillectomy in this series are similar to that from previous studies. The uptake of prosthetic rehabilitation was low and overall QOL was rated as fair. QOL should be considered as part of treatment outcome measure for maxillectomy.

“…[3] The ensuing defect creates oronasal and oroantral communication leading to difficulties in mastication, hypernasal speech, fluid leakage and various degrees of cosmetic concerns. [4] These post-surgical effects usually have serious consequences as they affect the form and function of normal stomatognathic system leading to a reduction in quality-of-life of the patient. [5] Early management is therefore important in retaining function and enhancing the patient's self-esteem.…”

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.Aim: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.Materials and 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).Conclusion: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.
