1/3. Odontogenic sinusitis causing orbital cellulitis.BACKGROUND: Odontogenic sinusitis is a well-recognized condition that usually is responsive to standard medical and surgical treatment. Current antibiotic therapy recommendations are directed against the usual odontogenic and sinus flora. CASE DESCRIPTION: The authors present a case of a patient with acute sinusitis initiated by a complicated tooth extraction that did not yield readily to standard treatment. The case was complicated by orbital extension of the sinusitis. The authors isolated methicillin-resistant staphylococcus aureus, or MRSA, species from the affected sinus that usually is not encountered in uncomplicated acute nonnosocomial or odontogenic sinusitis. CLINICAL IMPLICATIONS: Though such forms of resistant microbial flora as MRSA are rare, they may be seen in patients who have a history of intravenous, or i.v., drug use and in immunocompromised patients. Management of patients with orbital extension of sinusitis requires hospitalization and i.v. antibiotic treatment.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/3. Healing of maxillary sinusitis of odontogenic origin following conservative endodontic retreatment: case reports.Because of the anatomical proximity, infection of posterior upper teeth can spread into the maxillary sinus. When confronted with a large persistent periapical lesion on a posterior maxillary root-treated tooth, the practitioner should question the quality of the previous endodontic treatment, evaluate the impact of the potential causes of failure and consider, in the majority of cases, the conservative non-surgical retreatment instead of extraction or periapical surgery of the dental element. This paper reports two cases of healing of extensive periapical bone destruction and of the co-existing sinus pathology of odontogenic origin after non-surgical endodontic retreatment of previously root-treated upper molars. Misconceptions concerning the role of epithelium in the periapical lesion are discussed. Also, emphasis is put on the need of precise radiological diagnosis, pre-operatively as well as post-operatively to ascertain healing and to avoid unnecessary delay in the appropriate management of these patients.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
3/3. Endoscopic extraction of an ectopic third molar.An ectopic third molar within the maxillary antrum was found to be the etiology of recurring sinusitis. The fully erupted tooth was extracted endoscopically.- - - - - - - - - - ranking = 4keywords = extraction (Clic here for more details about this article) |
