Aspergillosis of the Maxillary Sinus Associated With Dental Implant.

Aspergillosis is a fungal disease caused by the fungus Aspergillus; this disease frequently involves the lungs and occasionally the maxillary sinus. Aspergillosis in the maxillary sinus usually has the characteristics of a noninvasive form. It has been suggested that spores of aspergillus can be inhaled into the maxillary sinus via the osteomeatal complex or via an oroantral fistula after dental procedures, such as an extraction. However, maxillary aspergillosis related to implant installation has rarely been reported. This report regards unusual cases of maxillary aspergillosis associated with dental implant therapies in healthy patients. The cases were successfully treated with the surgical removal of the infected or necrotic tissues.

Concomitant injuries and complications according to categories of pan-facial fracture: a retrospective study.

PURPOSE: The purpose of this study was to investigate concomitant injuries and complications in patients with panfacial fracture (PF) according to patterns of PF. MATERIALS AND METHODS: PF is defined as fractures involving at least three of the four facial parts (frontal, upper midface, lower midface, and mandible). The data for this study were retrospectively analysed. A simple regression analysis, Cramer's V analysis, and Pearson's correlation analysis were used for verifying significance and correlation between the investigated factors and patterns of PF. Short-term postoperative surgical complications were classified according to the Clavien-Dindo classification (CDC). RESULTS: There was a statistically significant association between age and PF pattern (ULM: 44.9 ± 19.2; FUL: 42.0 ± 16.8; FULM: 33.6 ± 15.3; FUM: 65; p = 0.024), between the cause of injury and PF pattern (p = 0.047), and between operative time and fracture pattern (ULM: 4h 45min ± 2h 21min; FUL: 5h 19min ± 2h 54min; FULM: 7h 19min ± 4h 13min; FUM: 2h 15min ± 0; p = 0.008). 89% of patients had concomitant injuries in other body parts. In the CDC grade groups, rade IVa cases (n = 4) showed statistically significant differences with PF patterns (p = 0.006). Of all the patients, 58.6% (n = 58) complained of postoperative complications. CONCLUSION: PF patients can have different fracture patterns, depending on age and cause of trauma. Consequently, different PF patterns have different types of concomitant injuries and complications. PF patients with frontal area fracture have higher CDC grades, and may need ICU care. Therefore, classifying PFs will be a first step towards a systemic approach for treating and reducing complications.

Oral tuberculosis mimicking a traumatic denture ulcer.

Tuberculosis (TB) of the oral cavity may be overlooked in the differential diagnosis of oral lesions and can be misdiagnosed and managed incorrectly. A 66-year-old man with complete dentures presented with a nonhealing mucosal ulcer in the upper lip. Despite the treatments performed by a local medical clinic, the ulcerative lesion on the denture-bearing area had not improved over 5 months. A partial excisional biopsy was performed to investigate further. Histopathologic examination revealed granulomatous inflammation caused by TB, and a chest radiograph showed consolidation and cavitation of the upper lobes. The patient was diagnosed with pulmonary TB. This clinical report describes the management of oral TB mimicking a traumatic denture ulcer in a patient with long-term complete denture use.
