mr lymphography for sentinel lymph node detection in patients with Oral Cavity cancer preliminary clinical study
Head and Neck-journal for The Sciences and Specialties of The Head and Neck, 2018Co-Authors: Sohi Bae, Hojoon Lee, Woong Nam, Yoon Woo Koh, Eun Chang Choi, Jinna KimAbstract:BACKGROUND The purpose of this study was to evaluate the feasibility of MR lymphography with interstitial injection of a gadolinium-based contrast agent for identifying sentinel lymph nodes in patients with Oral Cavity cancer and clinically negative neck. METHODS Pretreatment MR lymphography with a differential subsampling with cartesian ordering (DISCO) sequence was performed in 26 patients with resectable Oral Cavity cancer and clinically negative neck, after peritumOral injection of 1-mL diluted gadobutrol. The accuracy of sentinel lymph node identification by MR lymphography was assessed and compared with the final histopathological results. RESULTS The MR lymphography consistently visualized the 44 sentinel lymph nodes in all 26 patients. In all but 1 patient with pathologically positive neck, assumed sentinel lymph nodes revealed metastatic involvement. CONCLUSION Pretreatment MR lymphography is a safe and feasible imaging technique that can help clinicians identify sentinel lymph nodes with a high risk of occult metastases in patients with Oral Cavity cancer, enabling focused preoperative biopsy in these high-risk patients.

primary tuberculosis of the Oral Cavity
Oral Diseases, 2005Co-Authors: Fabio Augusto Ito, C R De Andrade, Pablo Agustin Vargas, Jacks Jorge, Marcio Ajudarte LopesAbstract:Tuberculosis is one of the major causes of ill health and death worldwide. Nevertheless, tuberculous lesions of the Oral Cavity are rare and can be a diagnostic challenge, particularly in young immunocompetent patients. Most of the cases are secondary to pulmonary disease and the primary form is uncommon. In this paper, we present a case of primary Oral tuberculosis, affecting the floor of mouth in a 13-year-old Brazilian male patient.

oncologic safety of the submental flap for reconstruction in Oral Cavity malignancies
Otolaryngology-Head and Neck Surgery, 2013Co-Authors: Brittany E Howard, Thomas Nagel, Carrlene B Donald, Michael L Hinni, Richard E HaydenAbstract:ObjectivesTo evaluate the oncologic safety of the submental flap regarding potential transposition of involved nodes to the reconstruction site and recognize the submental flap as an excellent option for Oral Cavity reconstruction.Study DesignCase series with chart review.SettingTertiary academic referral center.Subjects and MethodsAll patients undergoing reconstruction with submental flaps following the resection of primary and recurrent malignancies of the Oral Cavity between 2002 and 2012 were reviewed. Analysis included tumor location, staging, reconstructive details, postoperative course, and outcomes.ResultsFifty patients were identified having undergone submental flap reconstruction of defects following resection for Oral Cavity malignancies. No patient had identifiable clinical or radiographic level I nodal involvement preoperatively. Patients’ ages ranged from 35 to 88 years (mean, 70 years). American Joint Committee on Cancer staging of patients included stage II (n = 16, 32%), stage III (n = 10...

oncologic safety of facial artery myomucosal flaps in Oral Cavity reconstruction
Head and Neck-journal for The Sciences and Specialties of The Head and Neck, 2016Co-Authors: S Ferrari, Andrea Ferri, Bernardo Bianchi, Andrea Varazzani, Francesco Giovacchini, Enrico SesennaAbstract:Background Buccinator myomucosal flaps are routinely used for Oral Cavity reconstruction and are indicated mainly in patients classified as having stage N0 cancer. This purpose of this study was to investigate whether preservation of the vascular pedicle of the flap (facial artery and vein) during stadiative neck dissection alters the oncologic safety in these patients. Methods Fifty patients underwent resection of T1 to 3, N0 squamous cell carcinoma of the tongue or floor of the mouth, stadiative neck dissection, and reconstruction with a facial artery musculomucosal (FAMM) flap were retrospectively analyzed concerning rate of occult neck metastasis and recurrences. Results Occult metastasis was detected in 10 patients. Mean follow-up was 41 months. The overall survival rate was 88%, and the disease-specific survival rate was 92%. Conclusion Neck dissection with preservation of the facial artery and vein does not alter the rate of regional recurrences, confirming the oncologic safety of myomucosal flaps in Oral Cavity reconstruction. © 2015 Wiley Periodicals, Inc.
