PurposeThe management of an infratemporal fossa abscess (IFA), which is a specific form of severe and advanced deep fascial space infections (DFIs), is mainly based on the traditional methods. The purpose of this study is to investigate the role of mandibular coronoidectomy in accelerating IFA healing.MethodsThis research is a single center retrospective study which composed of 23 IFA patients. The predictor variables were sex, age, diabetes, severity score and mandibular coronoidectomy. The outcome variables included hospitalization time (HT), and irrigating time (IT). A compare of treatment outcomes between the improved and the traditional surgical intervention of IFA was performed.ResultsCompared to patients in NC group (who did not receive mandibular coronoidectomy; HT/IT=17.54±1.80 / 38.54±3.73 days), our results showed that patients in AC group (who accepted mandibular coronoidectomy) had significantly decreased HT/IT (7.20±1.19 / 15.10±1.27 days; P<0.01). We also found 4 (31%) patients in NC group received reoperation for osteomyelitis, but no osteomyelitis and DFIs recurrence happened to patients in AC group.ConclusionsMandibular coronoidectomy with extra intraoral drainage could significantly accelerate the healing process of IFA patients and obviously decrease the reoperation rate for osteomyelitis.
