Temporomandibular joint involvement in malignant otitis externa: a case report

Malignant otitis externa (MOE) originates as inflammation of the epidermis in the external auditory canal, and spreads to the surrounding structures and neck, leading to abscess formation. MOE is associated with an immunosuppressive condition and diabetes. Patients with MOE suffer from otalgia, otorrhea and hearing loss. According to the literature, surgery to the temporomandibular joint is controversial as the treatment of choice.

USE OF A COMPUTER NAVIGATION SYSTEM FOR OSTEOTOMIES IN THE ORTHOGNATHIC SURGERY: TECHNICAL NOTE

Antibiotic prophylaxis in the operation of the closed mandibular fractures and the efficacy of postoperative antibiotics

PURPOSE: This study compared the frequency of postoperative infections in patients for a closed mandibular fracture with that without the ostoperative antibiotic prophylaxis. Patients and Methods: 48 patients without any specific medical history were divided into two groups depending on whether or not antibiotics had been applied after the surgery. The 24 patients in group 1 received only a second-generation cephalosporin (Cefotetan(R)) ntravenously from admission to immediate after the surgery. Likewise, 24 patients in group 2 received 1.0g of Cefotetan(R) twice daily longer than the third day after surgery. The mean (SD) duration of antibiotics administration after surgery was 6.9 (+/-3.56). The patients were evaluated after surgery for any postoperative infections according to the criteria: purulent drainage from a wound, spontaneous wound dehiscence accompanied by swelling, pain, and fever around the wound. RESULTS: Postoperative infections were encountered in 2 out of 24 patients in group 1, who received antibiotic medication until shortly after surgery, and in 3 out of the 24 patients in group 2, in whom the medication was continued even after the surgery. There was no sig nificant difference in the incidence of postoperative infections between the two groups. CONCLUSION: From this study, postoperative use of antibiotics seems to be unnecessary with view of the little significance of the factors that could affect the wound infection.
