A Case of Removal of Multiple Submandibular Gland and Duct Stones by Cervical Incision Approach / 대한이비인후과학회지

A calcified structure blocking the flow of saliva into the mouth is a major cause of salivary dysfunction. If a stone is detected, the goal of treatment would be to remove it. Furthermore, the fundamental treatment for preventing recurrence, although depending on the location and size of the stone, is salivary gland resection. The submandibular gland duct and hilum stone is usually removed by transoral approach. If there are multiple stones in the submandibular gland and the duct, it would be necessary to carry out resection of submandibular gland, using the intra-oral approach. We recently experienced a case of multiple stone in the submandibular gland and the duct in a 73-year-old man, who presented with the right submandibular area swelling after meals. We removed the submandibular gland and duct stone without intra-oral approach and present this case with a review of the literature.

Two Cases of Septal Perforation Repair using Posterior Margin Based Hinge Flap

Nasal septal perforation is a defect of cartilage, bone, or mucosa of the nasal septum. Nasal septal perforation has several potential causes such as previous septal surgeries, trauma, malignancy, inflammation, or drugs. According to previous studies, successful surgical outcome is affected by the size and location of the perforation. Although many surgical techniques have been reported, there is no standardized nor consistent surgical method for repairing nasal septal perforation. This report suggests a new surgical technique of repairing septal perforation using a posterior perforation-margin-based hinge flap.

A Case of Ceruminous Adenoma Arising from the External Auditory Canal / 고신대학교의과대학학술지

Ceruminous adenoma is a benign neoplasm of the ceruminous gland, and its development in human external auditory canal is very rare. Due to the limited number of cases, controversy still exists about nomenclature, classification, diagnosis and its treatment. Recently we experienced a 55 years old woman who was diagnosed with ceruminous adenoma of the external auditory canal, and who was treated with wide excision. So we report this uncommon case in combination with a review of the literature.

A Case of Dermatofibrosarcoma Protuberans was Misdiagnosed as Keloid of the Anterior Neck / 대한이비인후과학회지

Dermatofibrosarcoma protuberans is a rare type of cancer, a soft tissue sarcoma that develops in the deep layers of skin. It is a locally aggressive tumor with a high recurrence rate but the metastasis rarely occurs. The first sign of dermatofibrosarcoma protuberans is often a small bump on the skin. It may resemble a deep-seated pimple of rough patch of skin. The tumor typically grows slowly and can become a raised nodule. Therefore, it is likely to be misdiagnosed as keloid, basal cell carcinoma and scleroderma. We recently experienced a case of dermatofibrosarcoma protuberans in a 63-year-old man, who presented with anterior lower neck mass. We present this case with a review of the literature.

Incidence of Progression into Ménière Disease from Idiopathic Sudden Sensorineural Hearing Loss: Midterm Follow-up Study / 대한평형의학회지

OBJECTIVES: Ménière disease is a clinical syndrome characterized by the four major symptoms of episodic vertigo, sensorineural hearing loss, tinnitus, and aural fullness. Sensorineural hearing loss, especially low frequency, is the characteristic type of audiogram in Ménière's disease. However, it is difficult to distinguish idiopathic sudden sensorineural hearing loss (ISSNHL) with vertigo from the first attack of Ménière disease. The purpose of this study was to investigate the incidence of progression into Ménière Disease from low frequency ISSNHL. METHODS: Two hundred eighty-three patients were included in this study. We classified the patients with ISSNHL according to the hearing loss in audiogram and analyzed how many of them actually progressed to Ménière disease based on diagnosis criteria. RESULTS: Among the 240 patients, 37.1% (89 patients) were confirmed low frequency ISSNHL and 14.6% (13 patients) of them were diagnosed with Meniere disease. CONCLUSIONS: This study showed that the progression from low frequency ISSNHL to Ménière disease was higher than other frequency ISSNHL, as in other studies.

The Change of the Auricular Shape after Middle Ear Surgery Via Retroauricular Approach; Is the Reconstruction of Posterior Auricular Muscle Effective? / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Many patients experience middle ear surgery via retroauricular approach. While not a main interest of the surgery, the change of the auricular shape after surgery has been a subject of complaint by some patients. In this study, we wanted to determine if a change in the auricular shape occurs after middle ear surgery and evaluate the possibility of using reconstruction of posterior auricular muscle as a treatment option for this kind of change. SUBJECTS AND METHOD: Forth patients who received middle ear surgery were enrolled in this study. Retroauricular incision and canal up mastoidectomy were carried out to all patients. The patients were separated into two groups randomly before surgery: one group that had the reconstruction of posterior auricular muscle during surgery, and the other that did not. The average of heights of the helix was compared. Also, patients were asked to fill out a questionnaire about auricular shape before and after surgery. RESULTS: The heights of helix increased about 1.6 mm after surgery; however, the difference of increment as a result of reconstruction of posterior auricular muscle was not statistically significant. Questionnaire about the change of auricular shape after surgery showed that only 8% patients had noticed about the change of auricular shape after surgery. CONCLUSION: Most patients have no complaint about auricular shape after middle ear surgery via retroauricular approach. The average of heights of the helix increases after middle ear surgery. However, the reconstruction of the posterior auricular muscle is not effective for reducing the observed increment of heights of the helix following middle ear surgery via retroauricular approach.

A Case of Hyalinizing Trabecular Adenoma of the Thyroid Gland

Hyalinizing trabecular adenoma of the thyroid gland is a rare benign neoplasm. It is characterized by an encapsulated nodule, trabecular arrangement of polygonal, oval, elongated cells, and hyalinized stroma. It is easily confused with medullary thyroid carcinoma or papillary thyroid carcinoma. Distinguishment with pathologic finding and immunohistochemical studies are needed to make a definite diagnosis. We recently experienced a case of hyalinizing trabecular adenoma of the thyroid gland. A 73-year-old woman present with an incidentally detected left thyroid mass. Fine needle aspiration was performed and papillary thyroid carcinoma was suspected. However, the surgical specimen revealed a hyalinizing trabecular adenoma. We present this case with a review of the literature.
