RESUMEN
In the present study, the outcomes of elective neck dissection in patients with intrathoracic esophageal squamous cell carcinoma were investigated. From January 2016 to December 2022, 21 patients who underwent esophagectomy and elective neck dissection (both neck level IV) for intrathoracic esophageal squamous cell carcinoma were enrolled. Of these 21 patients, 19 patients were male and 2 were female. A total of 11 patients received concurrent chemoradiotherapy (CCRT) as preoperative treatment. As a result of elective neck dissection at both neck level IV, occult neck metastasis of esophageal squamous cell carcinoma was diagnosed in 3 cases, all of which involved left neck lymph nodes. The incidence of occult neck metastasis was statistically significant in patients with preoperative CCRT, high T stage and high N stage (P<0.05). In addition, 16 out of 21 patients had been under follow-up without disease recurrence after the completion of treatment. However, 3 out of 21 patients succumbed to esophageal squamous cell carcinoma and 2 out of 21 patients were alive with stable disease of esophageal carcinoma. The follow-up period was 19.2±18.4 months. In conclusion, three-field lymph node dissection for intrathoracic esophageal squamous cell carcinoma may be necessary in patients with certain phenotypes, such that collaboration between thoracic surgeons and otolaryngologists may help reduce surgical complications.
RESUMEN
The present study examined the clinical characteristics of patients with a final diagnosis of solitary large malignant lymphoma of the head and neck after surgery. Between January 2015 and December 2022, 13 patients with a final diagnosis of solitary large malignant lymphoma of the head and neck after surgery were enrolled. The most common symptom of solitary large malignant lymphoma was a neck mass (n=11; 84.6%). The most common sites of the head and neck were neck level II (eight patients), neck level IV (two patients), parotid glands (two patients) and the tongue (two patients). The number of malignant lymphomas was as follows: 11 patients had one large tumor and two patients had two large tumors. The mean tumor size was 4.0±1.3 cm (range; 2.7-6.8 cm). Among the two patients with two lymphomas, the size of the second neck mass was 3.2 cm in one patient and 2.7 cm in the other patient. The most common type of solitary large malignant lymphoma was diffuse large B-cell lymphoma (n=6, 46.2%). A total of 12 patients are currently under follow-up without disease recurrence after treatment completion and one patient diagnosed 1 month ago is currently undergoing radiation therapy. The follow-up period was 47.3±19.0 months (range; 1-62 months). The possibility of solitary large malignant lymphoma of the head and neck should be considered. As it is difficult to accurately diagnose solitary large malignant lymphoma before surgery, surgical resection is required for differentiation from other diseases.
RESUMEN
BACKGROUND/AIM: Recently, hyaluronic acid disc has been known to enhance the success rate of fat myringoplasty. However, hyaluronic acid disc (Epidisc) is not covered by south Korean medical insurance. To date, fat myringoplasty using middle ear packing has rarely been reported. In this study, we studied whether middle ear packing with dexamethasone soaked gelfoam and fibrin glue over the fat graft could promote the success rate of tympanic membrane perforation (TMP) closure without hyaluronic acid disc, regardless of perforation size. PATIENTS AND METHODS: Between January 2005 and July 2020, a total of 209 patients who underwent fat myringoplasty due to chronic TMP at a tertiary referral center were enrolled, and the success rate and audiologic outcomes were analyzed. RESULTS: The mean successful tympanic membrane (TM) closure rate was 88.0%. The success rate by different age groups showed no significant difference. Further, the size of perforation showed no significant difference, and the perforation site (anterior or posterior) was not significant. The preoperative mean thresholds of air conduction (AC), bone conduction (BC), and air-bone gap (ABG) were 55.71, 12.98, and 42.73 dB respectively. The postoperative mean thresholds of AC, BC, and ABG were 23.67, 12.98, and 10.69 dB, respectively. Change in preoperative and postoperative hearing showed was statistically significant. CONCLUSION: Middle ear packing by gelfoam combined with external ear canal packing using fibrin glue enabled stable adhesion between the remnant TM and the fat graft. Regardless of the size of the TMP, the success rate of the fat myringoplasty by our technique can be enhanced without use of hyaluronic acid disc.
