  • The purpose of this study was to analyze the color distribution of the maxillary primary central and lateral incisors using a dental spectrophotometer. Color measurements of maxillary primary central and lateral incisors of 32 pediatric patients aged 2 to 6 years were performed using SpectroShade Handy Dental Type 713000 (Serial No. HDL2678, MHT, Verona, Italy) by one researcher in the same clinic. CIE L*, a*, b* values of total surfaces and cervical, middle, incisal region were recorded. L* values were higher and a* values were lower in the primary central incisors than those in primary lateral incisors, but b* values didn't show statistical difference. L* values of the middle region were the highest, and a* and b* values decreased from the cervical region to the incisal region. There were significant color differences between each region, and ΔE*ab between each region were greater than ΔE*ab between the primary central and lateral incisors. For esthetic restorations of primary incisors, it is necessary to consider the color differences between each region rather than those between the primary central and lateral incisors.

  • Invasive cervical resorption is a relatively uncommon form of external root resorption. It is characterized by invasion of cervical region of the root by fibrovascular tissue derived from the periodontal ligament. This case presents an invasive cervical resorption occurring in maxillary lateral incisor, following damage in cervical cementum from avulsion and intracoronal bleaching procedure. Flap reflection, debridement and restoration with glass ionomer cement were performed in an attempt to repair the defect. But after 2 mon, more resorption extended apically. Considering root stability and recurrence potential, we decided to extract the tooth. Invasive cervical resorption in advanced stages may present great challenges for clinicians. Therefore, prevention and early detection must be stressed when dealing with patients presenting history of potential predisposing factors.

  • Cervical chondrocutaneous branchial remnants are very rare congenital lesions of the lateral neck; thus, our knowledge of this condition derives almost entirely from occasional case reports in the literature. They are thought to originate from the branchial arches and, therefore, can be found anywhere on the pathway along which those branchial arches migrate during embryogenesis. We report the case of a 5-year-old girl presenting with a cervical chondrocutaneous branchial remnant on the right lateral neck that had existed since birth, with no other anomalies.

  • Chronic lymphedema is caused by an impairment of the lymphatic system due to primary or secondary causes. Vascularized lymph node transplantation (VLNT) is currently the most promising and frequently used technique besides lymphaticovenous anastomosis. However, the vessel anatomy in the lateral thoracic region is sometimes quite variable. Based on our experiences with vascular anatomical inconstancy in the lateral thoracic region, we planned a lateral intercostal artery perforator flap for VLNT in a female patient with chronic stage II lymphedema of both legs after cervical cancer treatment. After surgery, the patient reported significant improvement in limb volume and the accompanying symptoms. The limb circumference was reduced by an average of 19.2% at 6 months postoperatively. Despite having a short pedicle and small vessel caliber, the lateral intercostal artery perforator flap can safely be used for VLNT in lymphedema patients with anatomical variants.

  • Extraparotid Warthin's tumor(EPWT) is a rare disease entity; its incidence is about 8% of Warthin's tumor(WT). The periparotid and upper cervical lymph nodes are the most predilection sites. The lymphoid tissue of WT can act like a regional lymph node, and the necrosis and inflammation within the tumor are well known. In our cases, both 81-year-old man and 58-year-old man were visited our clinic, presented with upper lateral neck mass that had been present for the last few months. We operated the excisional biopsy in level ll of neck. The pathologic examination was proven to be EPWT. We report the unique two cases of extraparotid Warthin's tumor with literature review.

  • The Neurofibroma is a benign neoplasm originating from neural tissue such as Schwann cell, fibroblast and peripheral fibroblast, which rarely converts to malignancy. About 25-45% of neurofibroma are located in head and neck, and the most common sites are lateral cervical region and mouth. Because of its high vascularity and invasion to the adjacent organs, surgical resection may be confronted and limited, moreover large neurofibroma can cause large defect that needs various kinds of flap. The factors related to clinically suspected malignancy are painlessness, abrupt increase in size, firm fixation, and central ulceration, although the malignancy rate of neurofibroma is low. The complete resection was failed several times at local clinic, the patient was transferred to our hospital. We have successfully removed the retroauricular neurofibroma using transposition flap & free skin graft on its large defects.

  • Objectives: The purpose of this study was to determine whether the cranial vertebral angle (CVA) and the range of motion (ROM) was different between participants with a forward head posture (FHP), with or without pain. Methods: Forty-four participants who had FHP participated in this study. The FHP was assessed digitally by measuring a lateral view the CVA for each subject. A cervical ROM device measured the cervical ROM. The volunteers were allocated to either, with pain (n = 22), or without pain (n = 22) groups, and pain was evaluated using the Numeric Pain Rating Scale. Results: The FHP in the pain group showed a significant difference in the CVA, and the cervical ROM in both flexion and extension, compared with those in the FHP without pain group (p < 0.05). Logistic regression analysis indicated that the occurrence of cervical area pain was higher amongst subjects who had a decreased CVA and flexion motion. Conclusion: This study suggested that decreased CVA and cervical flexion range, were predictive factors for the occurrence of pain in the cervical region.

  • A group of 49 patients with neurogenic tumor in head and neck except intracranial tumor & Von-recklinghausen's disease was treated at the Department of Surgery. Presbyterian Medical Center during 12 years from January, 1980 to December, 1991. Of the 49 cases, 24 cases were neurilemmoma, 23 cases neurofibroma and 2 cases malignant schwannoma. The lateral cervical region was the commonest location of the neurogenic tumors, 24 cases (49%) arose from posterior triangle of neck and 12 cases from anterior triangle of neck. The origin of nerve was identified in 28 cases(57%). Cervical plexus(10 cases) and brachial plexus(7 cases) were most commonly affected. The most common site of neurogenic tumors arose from cranial nerve was anterior cervical triangle.

  • The cervical flap, comprising skin, fascia, and platysma muscle, has significant application in the head and neck region after radical ablative surgery for cancer of the oral cavity. The flap may be used for reconstruction of the cheek, floor of the mouth, and lateral side of the tongue. This flap minimizes donor morbidity by use of cervical operation wound and flap size available is adequate for most oral defects and the procedure is relatively simple and time-saving. However the flap is not applicable in patients where there are large tissue defects and metastasis is suspected. We have used the cervical flap for its rapid, simple, and effective closure of oral defects after cancer ablation and found it is very useful for the reconstruction of relatively small oral defects.

  • Background: The aim of this study was to clarify the topographical relationship between the accessory nerve (AN) and transverse cervical artery (TCA) to provide safe and convenient injection points for AN blockade. Methods: This study included 21 and 30 shoulders of 14 embalmed Korean adult cadavers and 15 patients, respectively, for dissection and ultrasound (US) examination. Results: The courses of the TCA and AN in the scapular region were classified into four types based on their positional relationships. Type A indicated the nerve that was medial to the artery and ran parallel without changing its location (38%). In type B (38%), the nerve was lateral to the artery and ran parallel without changing its location. In type C (19%), the nerve or artery traversed each other only once during the whole course. In type D (5%), the nerve or artery traversed each other more than twice forming a twist. At the levels of lines I-IV, the nerve was relatively close to the artery (approximately 10 mm). TCAs were observed in all specimens around the superior angle of the scapula at the level of line II, whereas they were not found below line VI. In US images of the patients, the TCA was commonly observed at the level of line II (93.3%) where all ANs and TCAs were observed in cadaveric dissection. Conclusions: The results expand the current knowledge of the relation between the AN and TCA, and provide helpful information for selective diagnostic nerve blocks in the scapular region.
