RESUMO
BACKGROUND: The overall purpose of this clinical study is to evaluate the effectiveness of bovine-derived collagen in surgical oral mucosal defects. PATIENTS AND METHODS: The study model included thirty-two patients who underwent surgery for benign and malignant lesions of oral cavity in the Indira Gandhi Medical College and Research Institute, Puducherry, India-from 2012 to 2018. The surgical oral mucosal defects had been reconstructed with a commercially available bovine-derived type I collagen [Surgicoll-Mesh, 0.5 mm thick] membrane. The clinical effectiveness of this collagen membrane was evaluated using parameters like haemostasis, pain, epithelialisation, granulation tissue formation and mouth opening as the functional test parameter. RESULTS: The clinical outcome results documented proved that the bovine-derived collagen membrane showed excellent significant results with respect to haemostasis, pain relief, epithelialisation and granulation tissue formation.
RESUMO
Metastasis to the oral region is very rare and accounts for less than 1% of oral malignant tumors. Breast, lung, kidney, adrenal, gastro intestinal tract and prostates are most common primary tumors from which metastasis to oral region occur frequently. Metastasis from thyroid gland is extremely rare to oral region. We present an unusual case of metastatic follicular carcinoma of thyroid in maxilla. The significance of this report is that the secondary lesion was the only symptom of the primary tumor and helped us in diagnosis and treatment of disease.
