Ameloblastic carcinoma of lower jaw (case report)

The study objectiveis to report a case of mandibular ameloblastoma.Materials and methods. A 30-year-oldfemale patient presented with swelling of the right mandibular region that appeared 8 months ago and has been slowly increasing. The patient had no other symptoms, such as pain, anesthesia, paresthesia, difficulty swallowing, mouth opening, speech disorders, fever, chills, or weight loss. Orthopantomography revealed pronounced bone resorption in the right portion of the mandibular body. Computed tomography showed a cystic cavity in this area. After incisional biopsy, the patient was diagnosed with ameloblastic carcinoma. We performed segmental mandibular resection and installed a reconstructive plate to restore mandibular integrity. We also performed selective cervical lymph node dissection (levels Ia and Ib).Results.One yearpostoperatively, the results were considered aesthetically and functionally satisfactory.Conclusion.We observed an aggressive disease phenotype with extensive localized bone destruction, typical of ameloblastic carcinoma. Extensive excision of the primary tumor and selective cervical lymph node dissection without radiotherapy ensured a relapse-free period during patient’s follow up.

The Impact

Abstract Background The aim of this study was to evaluate the impact of cervical lymph node dissection on acid and duodenogastroesophageal reflux (DGER) in patients undergoing transthoracic esophagectomy with gastric tube reconstruction and intrathoracic esophagogastrostomy. Methods Thirty one patients receiving transthoracic esophagectomy gastric tube reconstruction by intrathoracic esophagogastrostomy were subjected and divided into two groups: two field lymph node dissection group (the 2F group) and three field lymph node dissection group (the 3F group). All patients underwent 24h pH and bilirubin monitoring and gastrointestinal endoscopy one year after surgery. The results of 24h pH and bilirubin monitoring, endoscopic findings, and reflux symptoms, were compared between two groups. Results No acid reflux was observed in the 2F group, whereas it was observed in 6 (40%) of the 3F group (P = 0.023). DGER was observed in 2 patients (13%) of the 2F groups, whereas it was observed in 8 (53%) of the 3F group (P = 0.007). The percentage time of acid reflux in the 3F group was significant higher than that in the 2F group (median 0.8 vs 0%, P = 0.008). The percentage time of bile reflux in the 3F group was also significantly higher than that in the 2F group (median 2.600 vs 0%, P = 0.027). Four patients (25%) had reflux esophagitis in the 2F group, and nine patients (60%) had reflux esophagitis in the 3F group (P = 0.048). Conclusion Cervical lymph node dissection increases acid reflux and duodenogastroesophageal reflux, and can lead to the increase of the incidence of reflux esophagitis in patient with intrathoracic esophagogastrostomy.

Objective To investigate whether intraoperative neuromonitoring (IONM) has a significant advantage in reducing the incidence of recurrent laryngeal nerve (RLN) injury. Methods Patients who underwent thyroid and parathyroid surgery from October 2012 to December 2017 at the Center for Thyroid and Breast Surgery of Xuanwu Hospital were retrospectively analyzed. They were divided into the IONM group and visualization alone group (VA group) according to whether IONM was used. Results In total, 1696 nerves at risk of injury (IONM group, n = 1104; VA group, n = 592) were included in the analysis. Among the high-risk nerves, permanent damage occurred in no cases in the IONM group but in one case in the VA group. Because the higher proportion of central lymph node metastasis caused difficulties in central cervical lymph node dissection and identification of the RLN, the patients undergoing lateral cervical lymph node dissection in the VA group had a significantly higher risk of postoperative RLN injury (11.76% vs. 0.00%). Conclusion IONM technology has advantages in protection of the RLN, especially in high-risk nerves and patients with a high proportion of central lymph node metastasis who require central and lateral cervical lymph node dissection.
