The spreading pathways which is the cause of infection on head and neck area are submandibular space, masticatory space, parapharyngeal space, retropharyngeal space, carotid sheath and mediastinum, etc. If spread to parapharyngeal area involving airway, such infection can be life-threatening by airway obstruction, or can cause vascular injury followed by hemorrhage, nerve injuries. Also, if spread to superficially, necrotizing fasciitis and many complications may occur including gangrene of skin. The key to successful treatment of infection on head and neck area is recognition of spreading pathways, early diagnosis and following therapeutic management. Our department present two cases, one is infection progressed superficially to suprasternal space, another is spreading deep according to parapharyngeal space, subclavian space and carotid sheath followed by airway obstruction, and obtained significant results with surgical incision and drainage, administration of selected antibiotics, continuous post-operative treatment. We report these 2 cases with literatures review.

Some clinical diseases, such as granulomatous thyroiditis, tuberculosis, and sarcoidosis can cause granulomatous inflammation in thyroid, and theses have various clinical presentations. Granulomatous thyroiditis is an inflammation of thyroid gland, and may be painful and tender in case of infection, radiation, or trauma. Otherwise, autoimmune conditions, medications, or an idiopathic fibrosis may cause to be a painless thyroididtis. It is self-limited, possibly viral, inflammatory thyroid disorder usually presented with thyroid pain and systemic symptoms. Tuberculosis of the thyroid occurs only rarely and the patient may be asymptomatic. In thyroid sarcoidosis, most common findings are painless, progressive enlargement of the thyroid with normal function. We have experienced a case of chronic granulomatous inflammation of thyroid gland presenting as a painless thyroid nodule and report it with a review of literature.

A 66-year-old woman described a 6-month history of hoarseness after upper respiratory infection. She was a house wife and referred from an outside clinic under a diagnosis of vocal fold nodules. Strobovideolaryngoscopy revealed bilateral vocal fold lesions, and decreased mucosal wave of both vocal folds. She was brought to the operating room for microsuspension laryngoscopy. Under general anesthesia, dual intracordal cysts on left vocal fold were completely resected with microflap technique. The lesion on the right vocal fold turned out to be a reactive fibrous mass, which was also resected. Dual intracordal cysts were confirmed histopathologically. The one was an epidermoid cyst lined with squamous epithelium, and the other was a mucus retention cyst lined with cuboidal epithelium. Postoperative voice was acceptable by the patient and the mucosal vibration has much improved after the surgery.

HHPV (Human Papillomavirus) is a DNA virus that can cause benign lesions, genitourinary cancer, and oropharyngeal cancer by penetrating the mucous membrane and skin. It is widely known to be transmitted mainly through sexual contact. As with many viral infections, vaccines have been developed to prevent infection with HPV. Currently, in many countries, HPV vaccines are mainly used for national immunization for women to prevent diseases that traditionally occur frequently in women, especially cervical cancer. However, since the vaccination rate is relatively low, many countries are struggling with ways to increase the vaccination rate. Meanwhile, the incidence of oropharyngeal cancer caused by HPV in men has been increasing recently. In the United States, the annual number of oropharyngeal cancers in men already exceeds the number of cervical cancers in women, so HPV infection in men has emerged as a major problem. Accordingly, interest in HPV vaccination in men has also increased, and studies on the effectiveness and necessity of vaccination of both women and men compared to women alone are being actively conducted. In this paper, the evidence of HPV vaccination for men will be reviewed through previous studies, and its validity and cost-effectiveness will be analyzed to bolster the clinical usefulness of HPV vaccination for men.

A 38-year-old man, who was diagnosed nasopharyngeal carcinoma (stage T4N2Mx) had rapidly growing lower neck mass (at level IV area) with local inflammation sign during concurrent chemoradiotherapy. After we performed Color Doppler sonography and fine needle aspiration biopsy of the neck mass, we differentiated neck soft tissue infection from tumor extension. Size of the mass decreased after antibiotics therapy. It was difficult to differentiate neck infection from tumor progression during treatment in naspharyngeal carcinoma.

Tetanus is a life-threatening infection that is rare in the developed country. Because of the rarity: of the disease, the clinician may be unfamiliar with the clinical presentation and unsuspecting of the diagnosis. However, tetanus can rapidly progress into lethal muscle spasms accompanied by respiratory insufficiency, and it has a mortality of 15 to 30%. The most common presenting symptom was trismus, followed by neck pain, dysphagia, generalized pain and facial muscle contractions. Dysphagia is a common symptom of tetanus, but not common as an initial symptom, the correct diagnosis and adequate therapy are likely to be delayed. Treatment involves administration of penicillin, tetanus immune-globulin, debridement of wounds, aggressive supportive care, and initiation of active immunization. We report an elderly woman presenting with dysphagia as an initial symptom of tetanus with review of literature.

Background and Objectives: In cochlear implant (CI) surgery, the results and causes of revision and reimplantation may guide surgeons in establishing surgical protocols for revision surgery with safe audiological outcomes. The aim of this study was to review our experience in terms of etiology, surgical strategy, and hearing outcomes in pediatric patients who underwent CI removal and reimplantation. Subjects and Methods: All patients received implants of the same brand. Pre and postoperative Categories of Auditory Performance score and aided free-field pure tone audiometry thresholds were noted. In vivo integrity tests were performed for each patient and the results of ex vivo tests of each implant were obtained from manufacturer. Results: A total of 149 CIs were placed in 121 patients aged <18 years. The revision rate in children was 6.7% (10/121 children). Six patients had a history of head injury leading to a hard failure. The causes of reimplantation in others were soft failure (n=1), electrode migration (n=1), infection (n=1), and other (n=1). All patients showed better or similar postreimplantation audiological performance compared with pre-reimplantation results. Conclusions: It is very important to provide a safe school and home environment and educate the family for reducing reimplantation due to trauma. Especially for active children, psychiatric consultation should be continued postoperatively.

One hundred fifty four cases of branchial anomaly treated from January 1987 to July 1993 were analysed to determine clinical features, embryologic and anatomic types of the branchial cleft anomaly, to investigate the differences between adults and pediatrics, and to establish the appropriate treatment plan. The male to female ratio was not signifiacntly different in pediatric and adult patients. The mean symptom duration was 0.5 years(range 0.08-14 years) in pediatric patients and 1.67 years (0.7-7 years) in adult patients. The clinical presentations of these anomalies were lateral neck mass in 112(72.7%), infected discharge in 22(14.3%), non-infected discharge in 6(3.9%), and abscess in 14 cases(9.l%). Sites of the lesions were upper third of the neck in 93(60.3%), infraauricular in 35(22.7%), middle third of the neck in 17(11.0%) and inferior third of the neck in 9 cases(5.8%). The anatomic types were cystic form in 117(75.9%), sinus in 24(15.5%), and fistula in 13 cases(8.4%). Embryologic classification were 124 second branchial cleft anomalies(80.5%), 29 first branchial cleft anomalies(18.8%), and 1 third branchial cleft anomaly(0.6%). Immediate surgery under the uncontrolled infection in 17 cases result in 82.4% recurrent rate(14 cases), and 17.6% cure rate(3 cases). Delayed surgery under the controlled infection in 8 cases recurrent rate(1 case), and 87.5% cure rate(7 cases). In summary, the most common branchial cleft anomaly is second type cyst both in pediatric and adult group, delayed surgical exterpation after infection control with I & D or antibiotics may give a good chance for care and may reduce the recurrence.
