RESUMO
Heterotopic salivary gland tissue (HSGT) consists of salivary tissue in places where it does not normally exist. Usually, HSGT presents as a draining sinus or nodule of the neck. The pathogenesis of HSGT of the neck remains uncertain. But HSGT in the neck is most widely thought to arise from defective closures and ectodermal hetroplasia of the precervical sinus of His. HSGT in the neck is rare and only a few cases have been reported in Korea. We recently experienced a case of HSGT in the neck presenting as a fistula of the anterior lower neck. We thought this as a 2nd brachial cleft anomaly; however, biopsy revealed HSGT. HSGT in the neck should be considered as one of the causes of a neck mass or fistula in children. Herein, we report this case of HSGT with a literature review.
RESUMO
The aim of this study was to develop evidence-based recommendations for determining the surgical extent in patients with locally invasive differentiated thyroid cancer (DTC). Locally invasive DTC with gross extrathyroidal extension invading surrounding anatomical structures may lead to several functional deficits and poor oncological outcomes. At present, the optimal extent of surgery in locally invasive DTC remains a matter of debate, and there are no adequate guidelines. On October 8, 2021, four experts searched the PubMed, Embase, and Cochrane Library databases; the identified papers were reviewed by 39 experts in thyroid and head and neck surgery. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach was used to assess the quality of evidence, and to develop and report recommendations. The strength of a recommendation reflects the confidence of a guideline panel that the desirable effects of an intervention outweigh any undesirable effects, across all patients for whom the recommendation is applicable. After completing the draft guidelines, Delphi questionnaires were completed by members of the Korean Society of Head and Neck Surgery. Twenty-seven evidence-based recommendations were made for several factors, including the preoperative workup; surgical extent of thyroidectomy; surgery for cancer invading the strap muscles, recurrent laryngeal nerve, laryngeal framework, trachea, or esophagus; and surgery for patients with central and lateral cervical lymph node involvement. Evidence-based guidelines were devised to help clinicians make safer and more efficient clinical decisions for the optimal surgical treatment of patients with locally invasive DTC.
RESUMO
Background and Objectives@#Traditionally, transoral laser microsurgery (TLM) is commonly used to treat early glottic cancer. However, the long-term oncologic results have not been thoroughly investigated. Therefore, this study aimed to analyze long-term oncologic outcomes of TLM for early glottic cancer.Subjects and Method We retrospectively studied 132 patients who underwent TLM for early glottis cancer from January 2001 to August 2020. We assessed overall and disease-free survival according to the T classification and types of cordectomy proposed by the European Laryngological Society in 2007. @*Results@#Of the 132 patients, 125 were male and 7 female. The mean age was 61.6±9.3 years. We found 5 (3.8%), 112 (84.8%), and 15 (11.3%) patients staged as CIS, T1, and T2, respectively. For the cordectomy types, there were 6 in type I, 22 in type II, 83 in type III, 6 in type IV, 13 in type V, and 2 in type VI. Ten-year overall and disease-free survival rates were 99.2% and 87.1%, respectively. Overall and disease-free survival curves were not different according to different T classification and cordectomy types. @*Conclusion@#TLM is an excellent treatment modality for the long-term oncologic control of early glottic cancer.
RESUMO
Background and Objectives@#The head and neck multidisciplinary team (MDT) approach plays a crucial role in bringing together the ideas of various medical professionals. This study aimed to evaluate the early characteristics of the MDT approach for head and neck cancer and analyzed patients’ satisfaction.Subjects and Method We analyzed 450 head and neck cancer patients who received MDT care from August 2014 to June 2022. Patient satisfaction with MDT care was evaluated by selfadministered questionnaires consisting of 9 questions. @*Results@#Of 450, 298 (66.2%) were male and 152 (33.8%) were female. The mean age was 60.8±14.7 year. The most common primary site was the larynx (17.3%), followed by the oral cavity and oropharynx. A total of 726 cases of the MDT approach were performed in 266 MDT sessions, and the mean number of patients per MDT session was 2.74. The number of medical professionals participating in MDT ranged from a minimum of 3 to a maximum of 9, with a mean of 5.11. The mean running time of MDT meetings per case was 19.51 minutes. The time of the 2nd MDT was significantly shorter than that of the 1st or 3rd MDT. The mean score was close to very satisfactory in each of the 9 patient satisfaction questions. @*Conclusion@#We believe that the MDT approach is feasible and recommend its introduction for the treatment of head and neck cancer as most patients have shown very high satisfaction. Further studies on the role and efficacy of MDT care for head and neck cancer are necessary.
RESUMO
Background and Objectives@#Toxoplasmosis is a disease caused by an intracellular parasite, Toxoplasma gondii. There has been only a few studies done on cervical toxoplasma lymphadenitis, and this study was performed to evaluate its clinical characteristics and outcomes.Subjects and Method We retrospectively reviewed the patients diagnosed with cervical toxoplasma lymphadenitis from January 2010 to December 2019. We investigated clinical pathologic findings, treatment and clinical outcomes. @*Results@#Enrolled in the study were 21 patients who were confirmed with typical pathologic findings in an excisional biopsy (16/21) and core needle biopsy (5/21). Nine patients were male and 12 patients were female, with the mean age of 46.1±13.59 (19-70). All patients complained of neck masses and 5 (23.8%) patients showed pain or tenderness. Only one (4.8%) patient had mild fever. Fine needle aspiration cytology was performed in 5 patients, with no resulting pathognomonic outcomes in any one of the patients. CT scan was performed in 15 patients, with 8 (53.3%) patients showing multiple nodal enlargements but 7 (46.6%) patients showing a single enlarged lymph node. The most frequently involved location was level I (53.3%), followed by level II (46.6%), level V (46.6%), level III (40.0%), and level IV (20.0%). The serologic test for toxoplasma revealed positive IgG (100%) and IgM (85.7%). Treatments were excision only (61.9%) and excision with pharmacologic treatment using sulfonamide or pyrimethamine (38.1%). There was no case of recurrence after treatment. @*Conclusion@#Cervical toxoplasma lymphadenitis can be diagnosed by biopsy but needle aspiration has little role. It shows favorable clinical outcomes after treatment.
RESUMO
Background and Objectives@#The standard surgical procedure for primary hyperparathyroidism is the bilateral exploration. However, the unilateral exploration and direct focused parathyroidectomy have been performed to reduce surgical morbidity. The purpose of this study was to report the surgical outcomes and efficacy of the bilateral exploration, unilateral exploration, and direct focused approaches for primary hyperparathyroidism.Subjects and Method We retrospectively analyzed the surgical outcomes of 87 patients with primary hyperparathyroidism from January 2007 to December 2017. We compared the operative time, complication and recurrence rate between the three operative methods. @*Results@#The most common histopathology was parathyroid adenoma, which was found in 73 cases (83.9%), followed by hyperplasia. In terms of complications, there were two cases of transient vocal cord palsy, one case of hematoma, one case of hypocalcemia and one case of hungry bone syndrome. Recurrence occurred in two (2.3%) out of 87 cases. There was no significant difference in the recurrence rate between the three surgical approaches. @*Conclusion@#The success rate of surgery for primary hyperparathyroidism is high. Direct focused parathyroidectomy may be a good option for parathyroid adenoma if the localization tests localize the lesion. The bilateral exploration is effective for parathyroid hyperplasia.
RESUMO
Pilomatricoma(or calcifying epithelioma) is a not common benign solitary tumor originated from outer root sheath cell of hair follicle or hair follicle of sebaceous glands. The tumor usually presents as an asymptomatic, hard, superficial located, and skin colored to reddish blue cutaneous mass. Most of the tumors are less than 10mm in diameter and adherent to the skin. Recently, 48-year-old man presented with cheek mass. The tumor was 2.6cm sized and located at the subcutaneous layer of cheek on CT scan. The tumor was clearly removed via transoral approach with buccal incision leaving no wound on face. The mass was confirmed as pilomatricoma on pathologic examination. Herein, we report our experience with literature review.
RESUMO
Objectives@#. This study was conducted evaluate the efficacy of electromyography (EMG) using transcartilaginous (TC) electrodes through the thyroid cartilage and perichondrium. @*Methods@#. We prospectively collected EMG data from intraoperative neuromonitoring (IONM) of 54 nerves at risk in 38 patients during thyroidectomy. We followed standardized IONM procedures in all operations. EMG signals from both endotracheal tube (ET) electrodes and TC needle electrodes were recorded simultaneously. We compared the characteristics of the EMG signals and the efficacy of both methods. @*Results@#. Significantly higher mean EMG amplitudes were recorded by TC electrodes than by ET electrodes in all four-step procedures (V1-R1-R2-V2, P<0.001). Loss of signal (LOS) occurred in five patients in ET electrodes, but in only two patients in TC electrodes. Postoperative laryngoscopy revealed recurrent laryngeal nerve palsy in the two patients who showed LOS from both the ET and TC electrodes, and vocal cord movement was intact in the other three patients. Therefore, the positive predictive values of LOS in ET and TC electrodes were 40% and 100%, respectively. @*Conclusion@#. EMG recording using TC needle electrodes is feasible and effective, making it a good alternative technique for IONM.
RESUMO
Background and Objectives@#Several studies have assessed the impact of laryngopharyngeal reflux disease (LPRD) on the health-related quality of life (HR-QoL), showing significant impairment of HR-QoL. This study aims to assess the impact of proton pump inhibitor (PPI) treatment of LPRDs to enhance HR-QoL.Subjects and Method We prospectively collected data from LPRD patients from April 2017 to July 2019. Patients who have reflux symptom index (RSI) of ≥13 or reflux finding score (RFS) of ≥7 were enrolled in this study. We assessed HR-QoL using a questionnaire with EORTC QLQ-H&N35, -C30 on the first visit. Patients were treated with PPI (Ilaprazole 20 mg/day) on their visits at 4, 8, and 12 weeks. RSI and RFS were measured at each visit and HR-QoL was reevaluated on the last visit. @*Results@#Ninety-five patients completed the 3-months follow-up and were enrolled in this study. Female : male ratio was 71:24 and the mean age was 57.0±11.9 (27-80). The initial RSI and RFS were 16.3±8.8 and 12.6±2.9, respectively, but were changed to 11.1±9.7 and 9.7±2.6 (p<0.001 in both) at 12 weeks after the treatment. Global health status/QoL, speech problem, dry mouth, and coughing were significantly improved. @*Conclusion@#PPI administration is effective in treating LPRD, where effects begin to appear at 4 weeks after treatment. HR-QoL was also improved in patients who have RSI improvement.
RESUMO
Tuberculous spondylitis, also known as Pott's disease, is a disease involving the spine with progressive destruction. It most commonly involves the thoracic and lumbosacral spine and may result in severe deformity or neurologic deficit. Although cervical spine involvement is rare, it can cause life threatening event. Recently, 70-year-old man presented with progressive dyspnea and dysphagia. Physical examination and radiologic studies showed a huge retropharyngeal abscess with bony erosion and sclerotic change at the adjacent cervical spine. After incision and drainage, it was finally confirmed as a tuberculous abscess. Herein, we report our experience with literature review.
RESUMO
Rosai-Dorfman disease, also known as the sinus histiocytosis with massive lymphadenopathy, is a rare and benign histioproliferative disease in which lymphadenopathy results from infiltration and dilatation of lymph node sinuses by large histiocytes. We experienced a case of a 59-year-old man, presenting bilateral cervical masses with pain since one month ago. Radiologically, there were multiple enlarged lymph nodes with homogenous contrast enhancement at both cervical areas. Excisional biopsy revealed that the tumor was consistent with the Rosai-Dorfman disease. The patient was treated successfully with corticosteroid. Herein, we report our experiences with literature reviews.
RESUMO
Large cell neuroendocrine carcinoma is a rare epithelial neuroendocrine malignancy and is preferentially located in gastrointestinal tract and pancreas. Cases of large cell neuroendocrine carcinoma have been reported in many other locations, including the thymus, gallbladder, prostate, larynx, salivary glands, nasopharynx, tonsil and mastoid. However, primary sinonasal large cell neuroendocrine carcinoma never have been reported in Korea. We experienced a case of primary large cell neuroendocrine carcinoma arising from left maxillary sinus recently. A 82-year-old male patient presented with nasal obstruction and epistaxis. The biopsy revealed large cell neuroendocrine carcinoma with poor differentiation. After a general evaluation, the patient was staged as cT3N0M0. The patient was treated by combined radiotherapy and chemotherapy. We report this rare case with literature review.

BACKGROUND AND OBJECTIVES@#Infectious mononucleosis is mainly caused by Epstein-Barr virus infection and it presents sore throat, fever, tonsillar enlargement with exudate, cervical lymphadenopathy, hepatosplenomegaly, and etc. Therefore, it is often misdiagnosed with acute tonsillitis. The aim of this study was to evaluate the clinical characteristics of patients with infectious mononucleosis and recent changes.SUBJECTS AND METHOD: From January 2008 to December 2017, we retrospectively studied 83 patients who were diagnosed with infectious mononucleosis. We evaluated the patients' clinical characteristics such as sex, age, onset of disease, the department first visited, period of hospital stay, symptoms, signs, the results of serologic test, and complications.@*RESULTS@#Among 83 patients, 41 were male and 42 were female. The mean age was 16.1±7.28, with the oldest patient being 38 years old and the youngest patient being 2 years old. The proportion of patients older than 25 years was 10.8%. The most common symptom was sore throat (77%), followed by fever (67%), upper respiratory infection symptoms such as cough, sputum, rhinorrhea (37%), abdominal pain (16%), neck mass or neck pain (13%), and headache (4%). The most common sign was tonsillar enlargement (85%), followed by tonsillar white patch (68%), hepatosplenomegaly (67%), and cervical lymphadenopathy (60%). Complication occurred in 2 patients with mild jaundice, and there was no critical complication. The department patients first visited was mostly otolaryngology (61%), followed by pediatrics (21%), gastroenterology (9%), and others (6%).@*CONCLUSION@#Patients with infectious mononucleosis mostly appeared to have fever, pharyngitis or cervical lymphadenitis, and the complication rate was low. The primary infection age of infectious mononucleosis tended to increase in recent years. In adult patients, cervical lymphadenitis was less, and white blood cell count and the proportion of lymphocyte was lower compared to pediatric patients.
RESUMO
When parathyroid carcinoma occurs in the thyroid gland, it is very difficult to diagnose before surgery because imaging studies and aspiration cytology cannot distinguish parathyroid carcinoma from thyroid nodule or benign parathyroid disease. A 53-year-old male was referred to our hospital for assessment of hypercalcemia. He had suffered from chronic kidney disease for 13 years. A 2.5×1.5 cm hypoechoic nodule was noted in the left thyroid gland on ultrasonography, and it showed increased uptake on the sestamibi scan. Fine needle aspiration biopsy revealed it to be a parathyroid lesion, which was confirmed by surgery as parathyroid carcinoma completely surrounded by normal thyroid parenchyme. Because ultrasonography and aspiration cytology have only a limited role in distinguishing parathyroid carcinoma from thyroid neoplasm, suspicion of parathyroid carcinoma before or during surgery through careful examination can lead to complete resection at the initial surgery.
RESUMO
OBJECTIVES: The number of metastatic lymph nodes (LNs) and the ratio between the number of metastatic LNs and the total number of retrieved LNs (the LN ratio [LNR]) have been proposed as risk factors for recurrence of papillary thyroid carcinoma (PTC). However, the significance of the number of LNs and the LNR in patients with clinically node negative PTC has not been clearly determined. The purpose of this study is to evaluate their significance. METHODS: We retrospectively analyzed 382 patients with PTC who had undergone total thyroidectomy with prophylactic central neck dissection (CND) between January 2000 and December 2010. We excluded patients with lobectomy, concurrent lateral compartment neck dissection, a follow-up period less than at least 2 years, number of harvested central LNs less than or equal to one, clinically positive LN, distant metastasis, recurrent cancer or other types of malignancy. The correlations between recurrence and various clinicopathologic characteristics including tumor size, extrathyroidal extension (ETE), stage, number of metastatic central LNs, and the LNR were investigated. RESULTS: After a mean follow-up period of 82.2±26.4 months, recurrence occurred in 14 patients (3.7%). Tumor size ≥20 mm, maximal ETE, presence of central LN metastasis, number of metastatic LNs ≥2, and LNR ≥0.31 correlated with recurrence in the univariate analysis. However, tumor size ≥20 mm, maximal ETE, number of metastatic LNs ≥2, and LNR ≥0.31 were significantly associated with recurrence in the multivariate analysis (hazard ratio=6.61, 7.17, 3.43, and 11.23, respectively). CONCLUSION: The LNR and the number of metastatic LNs are independent prognostic risk factors for recurrence in patients with clinically node negative PTC, and these factors can be used to guide postoperative adjuvant therapy and follow-up strategy after prophylactic CND.

BACKGROUND AND OBJECTIVES: This study was performed to evaluate the long-term effect of adenotonsillectomy on childhood growth by examining preoperative growth status and presenting symptoms. SUBJECTS AND METHOD: One hundred and four patients who underwent adenotonsillectomy from January to December 2009 were enrolled in this study. Clinical data were collected from medical record reviews and through the administered questionnaire. We investigated symptoms and growth changes during 5 years following the surgery. RESULTS: The mean age of patients was 6.0±1.94 years (range, 3–10), with the male to female ratio of 62:42. Pre-operative symptoms were significantly improved after the surgery. The mean pre-operative height and weight percentiles were 53.6±27.4 and 59.6±29.2 at initial evaluation, and 67.1±26.4 and 59.6±28.6 at 5 years post adenotonsillectomy (p < 0.001, p=0.989), respectively. An increase in height percentile was more prominent in patients whose pre-operative height percentile was less than 50 compared to those with a percentile of 50 or more (p < 0.001). Weight percentile was significantly increased in those with the pre-operative weight percentile of less than 50 and decreased in patients with a percentile of 50 or more. CONCLUSION: Adenotonsillectomy has a positive effect on height growth in children with adenotonsillar hypertrophy, especially in patients whose height percentile is less than 50. Weight gain also can be expected in preoperative low-weight children.

Fine needle aspiration cytology is gold standard for diagnosis of thyroid nodule. However, it is not perfect and its results are cytologically indeterminate nodules (Bethesda classification III-V) in 15-30%, which remains diagnostic challenges. So, the method that provide information about cancer risk is necessary to establish management strategy. As results of studies about genetic changes in thyroid cancer, remarkable advances have been achieved in understanding thyroid carcinogenesis, which produced applications of molecular biomarkers and profiling panels for diagnosis of thyroid nodule. These tests help clinicians make decision regarding the need for surgery and the surgical extent. In this review, published researches related to molecular diagnosis of thyroid cancer are reviewed and performance of the diagnostic tests and its interpretation were discussed.

BACKGROUND AND OBJECTIVES: The main treatment of laryngopharyngeal reflux disease (LPRD) includes life style modification and proton pump inhibitor (PPI) medication. However, LPRD is sometimes refractory to PPI medication. The Reza band has been developed to exert external pressure on the upper esophageal sphincter thus preventing gastric acid reflux to the larynx and pharynx. The aim of this study was to evaluate safety and efficacy of using the Reza band in patients with LPRD. SUBJECTS AND METHOD: We prospectively enrolled 16 LPRD patients who were refractory to PPI medication and who had agreed to wear the Reza band. Patients were treated with the Reza band and PPI medication simultaneously or only the Reza band. We studied complications related to the Reza band, analyzed Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) before and after the application of the band up to 12 weeks. RESULTS: The Reza band was endured by 15 patients except one patient. One patient (6.25%) ceased wearing the band due to pain and discomfort in the neck. No major complications occurred, except one patient who reported mild neck discomfort when the band was applied. The mean value of RSI before the application of the Reza band was 12.31±6.43, which significantly improved at 8 weeks and 12 weeks (9.17±5.08, p=0.005 and 8.20±5.59, p=0.007, respectively) post-treatment. The mean value of RFS before the application of the Reza band was 13.50±2.97, which significantly improved at 2, 4, 8, and 12 weeks (p < 0.05) post-treatment. CONCLUSION: We conclude that the Reza band is safe and effective for the treatment of LPRD in properly selected patients.
