Moyamoya disease is characterized by progressive bilateral narrowing of the internal carotid arteries(ICA) and their main branches, and formation of a fine vascular network (moyamoya vessels) at the base of brain. Mild intellectual or motor impairment, or both can be seen in moyamoya disease patient. Patients having intellectual disability usually have malocclusions associated with oral habits such as tongue thrusting, bruxism, or clenching. A patient with moyamoya disease and cerebral palsy visited Chonbuk National University hospital for dental examination. She showed mild openbite on anterior teeth, and had oral habits such as mouth breathing, tongue thrusting, and drooling. She was treated with myofunctional therapy(MFT) whose purpose was to strengthen orofacial muscles. Lip closing force and bite force were recorded to evaluate the muscle tone. Tongue crib was delivered to restrict tongue thrusting habit, since her compliance to the MFT was decreased after 6 months of treatment. With the MFT and tongue crib, the openbite was fairly improved. When myofunctional therapy has difficulty in obtaining good compliances, the treatment should not be effective enough. Although intellectually disabled patients are not compliant enough, thus a habit breaking device should be needed to treat the openbite caused by oral habits, dentist should make an effort to do MFT, since it could reduce a treatment period, and enhance the stability.

The author observed the changes of vasculature of pre-and post-irradiation on DMBA induced rat tongue cancer. The study was performed by using vascular corrosion resin casting, and scanning electron microscopy. The results were as follows. 1. The capillaries runned parallely and formed bundles and, sometimes, plexus. The endothelial cells were arranged regularly and small pores were observed. 2. In irradiated normal tongue the capillaries were curved slightly and formed plexus on initial day of post-irradiation. On third day the capillaries and capillary pores were dilated and the endothelial cell arrangement was irregular. The effects of irradiation were gradually increased from initial to the 3rd day, though it was decreased after 7th day. 3. The vasculature of DMBA induced tongue cancer group were very irregular, and large avascular lesions were formed according to the cancer necrosis or tumor cell nest and the vasculature was narrowed and paralleled around the avascular lesion by compression of cancer cell nest. The vascular wall was roughened and dilated, forming club shaped or varix. 4. The vessels were curved and formed reticular network in irradiated DMBA induced tongue carinoma group. The free end of newly formed capillaries had regular width, and also irregular club shaped or aneurysmal dilatation were observed. The vascular structures were destroyed and vessels were fused in tumor necrosis lesion. The radiation effects were marked on the first and third day of irradiation and the effects were decreased after seventh day and showed capillary regeneration.

PURPOSE. Prevention of xerostomia and stress is important to prolong healthy life expectancy and improve the quality of life. We aimed to investigate the effects of tongue rotation exercise for increasing salivary secretions and stabilizing salivary stress hormone levels. MATERIALS AND METHODS. Twenty four participants without subjective oral dryness were enrolled. The exercises comprised tongue rotation exercise and empty chewing. The salivary stress hormone level was measured using a Salivary Amylase Monitor. Unstimulated whole saliva volume and salivary amylase activity were measured before tongue rotation exercise or empty chewing and subsequently 5, 10, and 15 minutes after these exercises. Differences in the rates of change of unstimulated whole saliva volume and salivary amylase activity were analyzed by repeated measure analysis of variance. RESULTS. Statistically significant differences among the rates of change were not observed after empty chewing for unstimulated whole saliva volume and salivary amylase activity at the four measurement times. However, the rate of change of unstimulated whole saliva volume and salivary amylase activity were statistically significantly different among the four time points: before the tongue rotation exercise and 5, 10, and 15 minutes post-exercise (P<.05 and P<.01, respectively). CONCLUSION. Tongue rotation is effective in increasing saliva secretion, reducing stress, improving oral function, and extending healthy life expectancy.

Metastatic tumors of the oral cavity are uncommon. Most of them are located in the mandible while only small percentage are found within the soft tissues. The common sites of metastases to the soft tissue of oral cavity were the tongue and gingiva and among the tongue, the base of tongue was most common. An explanation of the predilection may be due to a richer vascular supply within base of tongue. The authors have recently experienced a case of small cell lung carcinoma with base of tongue metastasis in a 81-year-old male who had foreign body sensation at swallowing and muffled voice for 2 months. So, we present this case with the review of literatures.

The purpose of this study was to (1) establish a Korean adult normative data for Iowa Oral Performance Instrument, (2) investigate the characteristics of maximal tongue and lip strength and tongue endurance scores according to age and gender, and (3) examine the correlation of those scores. The results showed that there were no significant differences of gender in maximal tongue strength and tongue endurance scores. But there were significant differences of age in maximal tongue and lip strength and tongue endurance scores. The data will provide an important database for speech language pathology with the purpose of diagnosis and treatment of tongue and lip dysfunction.

Schwannoma is a benign, slow-growing, tumor of the peripheral nerves without specific symptoms, so that early diagnosis may be difficult. Though approximately 25~40% of all schwannomas occur extracranially in the head and neck region, only 1% of schwannomas are reported in the oral cavity. An 18-years-old female patient visited our clinic with a mass on the middle-right-dorsal surface of the tongue slowly growing for 1.5 years. The patient underwent the surgical removal of the neoplasia under general anesthesia. The mass was well capsulated and a cleavage plane was easily found. There was no recidivation during the course of a one-year follow-up. The treatment for schwannoma is surgical excision of the lesion and recurrence after excision of schwannoma is rare. The final diagnosis is made after a histological examination. Differential diagnoses must be made in relation to malignant tumors and in relation to numerous benign neoformations based on epithelial and connective tissues.

Background: The tongue in groove technique (TIG) is a useful technique for the correction of the nasal tip projection and the nasolabial angle. The purpose of this study was to determine the utility of this technique for nasal tip rotation and projection correction in the Iranian society. Methods: This is a retrospective clinical trial study of 20 patients undergoing open septo-rhinoplasty using TIG technique from January 2017 to August 2019 at the oral and maxillofacial unit of Bu Ali Hospital and private sector. Preoperative and postoperative profile view photographs were compared to assess the changes in tip projection and rotation. Results: Fifteen patients (75%) had normal angular size, and 5 of them (25%) were not within the normal range after the surgery. The Fisher exact test showed that this success was statistically significant (P = 0.006). Ten patients (50%) had normal projection size, postoperatively. The Fisher exact test showed that this effect was statistically significant (P < 0.01) Conclusion: The study demonstrated the benefit of TIG on the correction of nasal tip projection and rotation.

The tongue is one of the most common sites of oral cancer. Glossectomy is known as the gold standard for tongue cancer treatment. However, surgical removal can lead to reduced mobility of the tongue and the patients may have difficulty performing normal oral functions like swallowing and pronunciation. Therefore, additional prosthetic consideration to supplement the function of the impaired tongue is needed for oral rehabilitation of such patients. Palatal augmentation prosthesis helps the tongue to reach the palate by lowering the position of the palatal polished surface. The oral functions of the patients with limited tongue mobility can be improved by the prosthesis. In this case, palatal augmented maxillary denture and conventional mandibular denture were fabricated for the completely edentulous patient with reduced tongue mobility after glossectomy due to tongue cancer. As a result, the oral functions of the patient were improved with the prosthesis.

Tongue tumors of pediatric patients are the most common soft tissue tumor of pediatric oral and maxillofacial tumors. There are many kind of pediatric tongue lesions such as hemangioma, lymphangioma, papilloma, and cyst. Most of these lesions are benign, but malignant tumors of tongue may be occurred. Therefore, malignancy should be ruled out. Sometimes, tongue lesions are present with dyspnea, dysphagia, dysarthria, bleeding, or cosmetic problem. We experienced a case of chronic inflammatory mass on posterior 1/3 of the tongue in 4 month old female patient. Swallowing difficulty and respiratory distress symptom occurred because of tongue mass effect. The tongue mass was confirmed as granulation tissue by microscopic examination. After excision of tongue mass, she had no problem with swallowing and breathing.

Objective : Halitosis, or bad breath, is a common concern for many people. The aim of this study was to investigate clinical characteristics of halitosis patients and correlation with their various associated elements. Methods: We surveyed 169 halitosis patients by reviewing questionnaires from the Halitosis Clinic in the Hospital of Oriental Medicine, Kyunghee University from January 2004 to March 2006. The questionnaires contained various items including sex, age, history of smoking and alcohol intake, duration of symptoms in a week, time and condition of severe halitosis, suggestive origin of halitosis, taste abnormality, oral hygiene, self-assessed halitosis severity, dry mouth, postnasal drip, tonsillolith, globus pharyngeus, reflux sensation, too much gas and Winkel tongue coating index. Volatile sulfur compounds were measured with a $Halimeter^{\circledR}$. Results : The halitosis patients actively carried out management methods such as non-smoking, moderation in drink, teeth brushing and tongue scraping in order to decrease their oral malodor. Tongue coating significantly affected the $Halimeter^{\circledR}$ reading score, and tongue coating and dry mouth significantly affected self-assessed halitosis severity. Conclusions: Our results suggest that tongue coating and dry mouth should be treated to improve satisfaction in halitosis patients.
