Retrospective Evaluation of Cases of Temporomandibular Joint Dislocation Treated in Barau Dikko Teaching Hospital, Kaduna, North-West, Nigeria.
Background Study: Temporomandibular Joint [TMJ] dislocation is an uncommon acquired facial deformity. The condition may be traumatic or non-traumatic, acute or chronic, bilateral or unilateral in presentation. The aim of this study is to analyze the causes, pattern, presentation, and treatments that was giving to patients that presented with TMJ dislocation in our Centre
Methods: This study is a retrospective analysis of TMJ dislocations treated in the Accident and Emergency Unit and Dental/Maxillofacial Clinic , Barau Dikko Teaching Hospital Kaduna, Nigeria, from April 2012 to December, 2019. Information was collected from patients’ record which includes: age, gender, causes, localization, frequency and therapy.
Results: Twenty-eight patients were included. The mean age was 37.80 years and commoner in females than males at the ratio of 1.3 to 1.00. Most of the cases were non-traumatic (n= 24, 85.7%), mostly bilateral (n= 22, 78.6%) and appeared in acute situation (n= 15, 53.6%). Twenty-four (84.7%) of the patients received conservative treatment, which consists of reposition of the TMJ with (57.1%) or without (28.6%) analgesic and sedation. Only one had acrylic bite block and three had surgical correction because of ineffective conservative treatment.
Conclusion: TMJ dislocation need urgent attention as it deprived the victims’ adequate nutrition because of swallowing problems and speech deficiency.
