The purpose of this study is to suggest computer assisted neck-base's landmark identification algorithms and measurement extraction methods from three-dimensional human scan data. So we developed the algorithms for automatic identification of landmarks related to the neck-base types. The subjects were 58 women $18{\sim}24$ years of age. Their body were measured directly and indirectly by using camera and three-dimensional body scanner. They were measured during the months of October in 2001. Based on the characters of classified neck-base types, algorithms for the automatic identification of landmarks and methods of automatic measurement are developed. The three-dimensional automatic measuring program is made by $C^{++}$ language. Using this program, 4 landmarks are identified and 6 items are measured. In the verifying the precision of automatic measurement, the height measurements(cervicale, side neck point, front neck point) were relatively accurate, but neck-base width measurement was measured wide.

Lymph node status is the single most important prognostic factor in oral cancer because lymph node involvement decreases overall survival by 50%. Appropriate management of the regional lymphatics, therefore, plays a central role in the treatment of the oral cancer patients. The purposes of this article are to present the history of neck dissections, including current neck dissection classification, describe the technique of the most common neck dissection applicable to oral cavity cancers, and discuss some of the complications associated with neck dissection. Finally, a brief review of elective neck dissection and sentinel lymph node biopsy will be presented. It is necessary that dentists have to be interested in oral cancer and these interest will make it possible to prevent oral cancer, detect it earlier and also improve the prognosis, survival and the quality of life of survivors.

Objectives : Patients with neck tumor and their family need every information about the disease. Especially, the size and location are confusing with verbal information. With the aid of CT, the problem had some answer, but it needs some medical education. We would like to know the usefullness of 3D reconstructed images in patient education about the disease. Material and Methods : Neck CT data were collected from 10 patients with various neck tumors and converted to 3D reconstructed images. Understanding of the patients about the size and location of tumors were rated from questionaires using axial CT images and 3D images. Results : Understanding score about 3D images were greater than that of CT images(p<0.006). Conclusion : 3D reconstructed images of CT could give the patients more real visual information about the disease.

Differential diagnosis of posterior neck pain is very challenging based on symptoms and physical examination only. Retropharyngeal calcific tendinitis is a rare and frequently misdiagnosed entity in various causes of neck pain. It results from calcium hydroxyapatite deposition in the longus colli muscle which is characterized by severe neck pain, painful restriction of neck movement, dysphagia, and odynophagia. We herein report a case of a patient with acute retropharyngeal calcific tendinitis, who complained of posterior neck pain, initially diagnosed and treated as a myofascial neck pain syndrome.

Tortuosity of the internal carotid artery is not a rare condition. A 68-year-old woman presented with a 3 years' history of a pulsatile tinnitus and throat abnormal sensation. On physical examination, a soft pulsatile mass on the left posterior oropharyngeal wall was noted. By neck CT and neck MRI the tortuous internal carotd artery was visualized. Otolaryngologists should recognize this anomaly and the patient should be made aware of their condition, because it may cause a fatal or near-fatal hemorrhage during surgical procedures in the pharynx, especially tonsillectomy and adenoidectomy and drainage of peritonsillar abscess. We report a case of a left internal carotid artery tortuosity as an oropharyngeal mass.

Ectopic thyroid glands generally occur in the midline as a result of abnormal median migration, and their presence lateral to the midline is extremly rare. We report a 83-year-old male with anaplastic carcinoma admix papillary carcinoma in the extrathyroid area. We suspected left lateral neck metastasis on preoperative fine needle aspiration result and computed tomography. the patient underwent total thyroidectomy and left selective neck dissection(level II, III, IV, V). The patient was diagnosed as having an ectopic thyroid gland on the lateral neck with anaplastic carcinoma admix papillry carcinoma. The patient is alive without incident of tumor recurrence at 5month after surgery and radiotherapy.

Cystic metastasis in the neck from pharyngeal cancer has often been mistaken for either primary squamous cell carcinoma of branchiogenic origin or branchial cleft cyst. The distinctive histological and clinical features of cystic metastasis reviewed after its correct indentification can lead to the discovery of an unsuspected primary lesion and result in specific treatment options. Recendy, the authors experienced three cases of cystic metastasis in the neck from pharyngeal cancer ; one was from nasopharyngeal squamous cell carcinoma and the other two were from tonsillar squamous cell carcinomas. This report summarizes our experiences and review of the literatures.

Langer's axillary arch(axillopectoral muscle) is a rare disease. It is a variant muscular structure of the axilla, which was described as Langer's muscle by Ramsay and Langer. It could evoke chronic ambiguous neck pain. Therefore, it should be considered, when the patient failed to find the origin of neck pain which do not react any treatment. If it were diagnosed, it can be easily managed. However, it is not well known to otorhinololaryngologitis. Here we reports the 53 years old female who developed pain on supraclavicular area as a result of an Langer's axillary arch.
