Analysis of clinical characteristics and treatment of oral and maxillofacial space infections

OBJECTIVE To analyse the clinical features of oral maxillofacial space infection,and explore the treatment effect of high incision drainage combined with hyperbaric oxygen therapy.METHODS A total of 240cases of patients with oral maxillofacial infection in our hospital from Jan.2009to Dec.2013were randomly divided into study group 123cases and control group with 117cases;the clinical data of patients were collected and infection sites and infection sources were explored,and the species of pathogenic bacteria was explored by bacterial culture.The control group was given conventional treatment,the study group used incision drainage combined with hyperbaric oxygen therapy.Clinical efficacy and incidence of complications were compared between two groups.SPSS17.0software was used for statistical analysis.RESULTS The main infection sites of this group of patients located in the submandibular space,accounting for 37.91%,followed by the infraorbital space(23.33%);the source of infections in dental was the highest(59.17%),followed by the gland infections(26.25%).Bacteria were cultured 186strains of pathogens,including gram positive bacteria 79strains,accounting for 42.47% and 107strains of gram negative bacteria,accounting for 57.53%.After treatment,in observation group,the total effective rate was 91.87%,82.05%in the control group,the observation group was significantly higher than that of the control group,with significant difference between the two groups(χ2=4.252,P0.05).CONCLUSIONS Hyperbaric oxygen combined with abscess incision drainage can effectively improve the clinical efficacy of oral and maxillofacial space infections and reduce the risk of complications which is worthy of clinical application.
