Varicocele is found in 8-20% of male population and comprises the most common etiology of male infertility. Abnormalities in sperm concentration, motility, and morphology are observed on 65 to 75% of varicocele patients. Improvements of such parameters are seen in 50 - 80% after surgical correction of varicocele, and fertility is achieved in 30 -40% of cases. We evaluated the results of surgical correction of varicocele in both infertile and non-infertile patients. The effects of varicocele and subsequent correction on semen parameters and pregnancy were also reviewed. From September 1987 to December 1995, 254 patients with varicocele were surgically corrected. Semen analysis were performed in 229 patients, revealing abnormalities in 153 (66.8%) patients. Degree of abnormalities was correlated with the grade of varicocele and presence of infertility (79.8%). Improvement of postoperative semen was observed in 112 (73.2%) of 153 patients with abnormal preoperative semen profiles. Improvement was not correlated with grade of varicocele or age, but significantly correlated with fertility status. Postoperative sperm concentration, morphology, and motility were significantly improved in grade II and III varicocele. Sperm motility was improved when correction were performed under 30 years of age. Pregnancy was confirmed in 27 of 88 (30.7%) of infertile patients, and fertility rate was correlated with preoperative sperm concentration and motility, but not correlated with varicocele grade and sperm morphology. Higher pregnancy rate was observed if sperm concentration >=40 X 106/ml, normal morphology >= 60%, and motility >=60% on the postoperative semen. In conclusion, varicocele patients with infertility are affected by grade, age, and surgical correction. Thus early diagnosis and treatment should be offered to all patients with varicocele with infertility.

SS-cream is a topical agent for treating the premature ejaculation (PE) which was made up with extracts of 9 oriental herbs (Ginseng Radix alba, Angelicae gigantic Radix, Cistanchis Herba, Zanthoxylli Fructus, Torilidis Semen, Asiasari Radix, Caryophylli Flos, Cinnamoni Cortex and Bufonis Veneum). According to the active compositions, the main mechanism of SS- cream on PE was thought to be the local desensitizing effect. In order to realize the pharmacological action of SS-cream on PE, we performed the corneal sensitivity test with SS- cream and lidocaine in the rabbit (n=80). Both SS-cream and lidocaine inhibited the pin-prick induced corneal reflex dose-dependently (p<0.001). The anesthetic effect of lidocaine was appeared 5 minutes after the application and the duration of action persisted for 10 minutes. The intensities of desensitizing effect of SS- cream were almost same with those of 2% lidocaine, but the time of onset and duration of action was longer than 2% lidocaine. The time of onset was 10 minutes and the duration of action was persisted for more than 30 minutes. There were no local histopathologic changes after the application of SS-cream and lidocaine. With these result, we can conclude that SS-cream has a desensitizing effect on the cornea of rabbit. The believed main pharmacologic mechanism of SS-cream on PE is the desensitization of the Local Surface sensitivity.

4.Sentinel Lymph Node Centered Selective Neck Dissection Does Not Have Benefits Over Supraomohyoid Neck Dissection in Patients with cT1T2N0 Tongue Cancer.
Korean Journal of Otolaryngology - Head and Neck Surgery 2018;61(10):528-531
BACKGROUND AND OBJECTIVES: This study aimed to evaluate the clinical efficacy of sentinel node centered selective neck dissection in patients with early stage tongue cancer (T1T2N0). SUBJECTS AND METHOD: Lymphoscintigraphy was performed for 12 patients, subsequently followed by sentinel node centered selective neck dissection. The location of the sentinel node, pathological confirmation of node metastasis, and follow-up recurrence were analyzed. RESULTS: In total, 19 sentinel lymph nodes were identified. Of these, 18 were located in levels I to III, and one in level IV. After surgery, 3 patients (25%) were diagnosed with neck node metastasis: two experienced sentinel node metastasis and one experienced skipped metastasis. During follow-up, 3 of the 12 patients (25%) experienced recurrence. CONCLUSION: The recurrence of lymph node could be covered with supraomohyoid neck dissection, which indicates that it has superiority over sentinel node centered selective neck dissection in preventing recurrence in T1T2N0 tongue cancer patients.

Traumatic pyriform sinus perforation is a very rare complication of endotracheal intubation. Forced insertion of endotracheal tube can tear pyriform sinus mucosa. Pyriform sinus perforation can result in deep neck infection which may be potentially lethal. We report a case of pyriform sinus perforation secondary to traumatic intubation, which was successfully treated with primary closure.

Congenital sialo-cutaneous fistula arising from the accessory parotid gland is extremely rare. Although the fistula tract can be successfully excised after making a skin incision along the skin tension line around the fistula opening, a facial scar inevitably remains. We here report a case of sialo-cutaneous fistula that was treated with chemocauterization with trichloroacetic acid (TCA). TCA cauterization is an easy and effective option for the treatment of congenital fistula from an accessory parotid gland, especially from the aesthetic point of view.

THE AIM OF STUDY: The transseptal-transsphenoidal approach (TSA) for pituitary tumors may alter nasal functions, including nasal respiration and olfaction. The aim of this study was to investigate the efficacy of TSA in terms of nasal functions. MATERIALS AND METHODS: Twenty two cases of pituitary tumors, managed at Seoul National University Hospital from May 1997 through March 1998, were included in this prospective study. Nasal functions were evaluated preoperatively and 2 months after the operation through symptom questionnaires, rhinomanometry, acoustic rhinometry and the butanol thres-hold test. RESULTS: The subjective nasal symptoms, including nasal obstruction and olfaction, were not changed following the operation in 72% and 86% of the cases, respectively. In the objective findings, total nasal resistance was not grossly changed after the operation, however, cross-sectional areas at C-notch and 3.3 cm from the anterior nasal spine increased significantly after the operation. Mucosal response to a topical vasoconstrictor after the operation was less effective than before the preoperation. CONCLUSION: TSA for pituitary tumors may be a safe and effective technique in preserving nasal functions subjectively and objectively.

Mandibular metastasis of thyroid carcinoma is extremely rare. We present the case of a 46-year-old woman who had bilateral huge cheek masses that had grown rapidly over several years. Intra-oral mucosal tissue biopsy and imaging work-up including computed tomography scan and magnetic resonance imaging were performed and the initial diagnosis was presumed to be central giant cell granuloma. Incidentally detected thyroid lesions were studied with ultra-sonography guided fine needle aspiration and diagnosed as simple benign nodules. Due to continuous oral bleeding and the locally destructive feature of the lesions, we decided to excise the mass surgically. To avoid functional deficit, a stepwise approach was performed: Firstly, the larger left mass was excised and the mandible was reconstructed with a fibular free flap. The final pathologic diagnosis was follicular thyroid cancer. Postoperative I-131 thyroid scan and whole body positron-emissions-tomography were performed. Right side mass was revealed as a thyroid malignancy. Multiple bony metastases were detected. Since further radioactive iodine therapy was required, additional total thyroidectomy and right side mandibulectomy with fibular free flap reconstruction was performed. The patient also underwent high dose radioactive iodine therapy and palliative extra-beam radiotherapy for the metastatic lumbar lesion. Follicular thyroid carcinoma should be considered as a differential diagnosis for mandibular mass lesions.

Heterotopic gastric mucosa tissue is also called gastric choristoma, and this type of lesion can be found anywhere in the alimentary tract. However, gastric choristoma in the pharynx is very rare; only 10 cases of pharyngeal gastric choristoma have been reported in the English medical literature. A 32-yr-old woman was referred to our institution for the evaluation of a large mass that originated from the posterior wall of the oropharynx. The mass did not cause any symptoms except for the occasional sensation of a foreign body. Gadolinium-enhanced T1 weighted imaging showed a 5 cm-sized mass with central enhancement and hypointense portions, yet the radiological diagnosis was not clear. Transoral mass excision was performed with using electrocautery for making the diagnosis and for treating the mass. The microscopic analysis revealed gastric choristoma.

BACKGROUND AND OBJECTIVES: Diagnosis of thyroid disease requiring surgery and subsequent thyroidectomy may affect patients' emotion and quality of life. The purpose of this study is to evaluate the patients' understanding and concern about the disease and recovery rate after thyroidectomy, and therefore to enhance the satisfaction of hospitalization. SUBJECTS AND METHOD: MethodZZSeventy-seven patients undergoing thyroidectomy in a tertiary hospital from April 2009 to October 2009 were enrolled. Questionnaires were filled out on the admission day, discharge day, and 2 weeks after operation. Questionnaires consisted questions regarding the understanding of the disease, details of concern, recovery rate after surgery, and satisfaction on hospitalization duration. Retrospective chart review was also performed. RESULTS: Many patients (42.9%) acquired their knowledge of thyroid cancer through the internet. The possibility of voice change was the major concern before surgery (46.8%), whereas the major postoperative concern was adjuvant therapy (37.7%). The patient group with higher understanding of the disease showed higher recovery rate than the others at the time of discharge (mean postdischarge surgical recovery 67.4% vs. 55.3%, p=0.01). The patient group with lower understanding wanted longer hospitalization than the other group at discharge (p<0.001). CONCLUSION: Patient education about the thyroid disease may reduce patients' anxiety and therefore may enhance subjective recovery rate and satisfaction of hospitalization.
