Food intake and swallowing are complicated and intriguing series of movements involving voluntary and involuntary activities of cranial and spinal nerves and muscles. They have two most important functions, that is, food passage from the oral cavity to stomach and airway protection. Tongue, buccinators, and hyoid bone and its muscular attachments are anatomic structures for swallowing of special interests. The swallowing process of liquid is commonly divided into oral preparatory, oral propulsive, pharyngeal, and esophageal stages according to the location of the bolus. The movement of the food in the oral cavity and to the oropharynx differs between eating solid food and drinking liquid.

We experienced a case of dental treatment under general anesthesia in a 22-year-old female patient with dysphagia and dental phobia following partial glossectomy. She was diagnosed of squamous cell carcinoma of tongue and received surgical, radiation treatment two years ago. We report the experiences of anesthetic management for dental treatment in a patient with dysphagia and dental phobia following partial glossectomy.

Renal cell carcinoma is the third most common metastatic tumor to the bone and soft tissues of the head and neck. The common sites of metastatic renal cell carcinoma in head and neck region are nasal cavity, paranasal sinuses, oral mucosa, gingiva, tongue, palate, lip as the favored site. The present paper deals with one patient with metachronous oral tongue, nasal cavity and suspicious brain metastases after 2 years of renal cell carcinoma nephrectomy. Also, the patient had history of total thyroidectomy for thyroid follicular carcinoma. Total excision of nasal cavity and tongue mass were performed. Therapeutic aspects are briefly reviewed in literature.

The reproducibility of cephalography in repeated exposures were studied by tracing and photographic subtraction. The materials consisted of 50 pairs of 'same day' radiograph taken under identical conditions. The evaluation included skull, cervical column, hyoid bone, pharynx, tongue, soft tissue profile resulting 43 items in tracing, and 19 items in photographic subtraction. The results obtained from the differences between each pair were as follows: 1. The means and standard deviations by tracing of skull, cervical column, hyoid bone, pharynx, tongue, soft tissue profile were 0.34±0.62㎜, 1.02±1.59㎜, 1.37±1.78㎜, 0.55±1.16㎜, 0.51±1.51㎜, 0.15±0.3㎜ each. 2. The means and standard deviations by photographic subtraction of skull, cervical column, hyoid bone, pharynx, tongue were 0.09±0.35㎜, 0.70±0.95㎜, 1.22±1.33㎜, 0.53±0.86㎜, 0.27±0.41㎜ each.

Patients with Pierre Robin sequence exhibit varying degrees of airway obstruction and feeding difficulty. In some patients, airway obstruction may be profound, warranting surgical intervention to maintain a patent airway. The purpose of this article is to highlight the advantages of the tongue-lip adhesion procedure for the management of airway obstruction in such patients compared to the currently available options.

Objective: The aim of this prospective, case-controlled study was to assess the difference of the amount of tongue coating between halitosis and non-halitosis patients using a digital tongue diagnosis system (DTDS). Methods: Sixty-five patients complaining of oral malodor were recruited for the study. The level of volatile sulfur compounds (VSC) in the oral cavity of the patients was measured by a portable gas chromatography. All patients were then divided into two groups, the halitosis group ($H_2S{\geq}1.5ng$/10ml, or $CH_3SH{\geq}0.5ng$/10ml) and the non-halitosis group ($H_2S$<1.5ng/10ml and $CH_3SH$<0.5ng/10ml), according to the VSC level criteria published by Tonzetich. Tongue images of the two groups were acquired and analyzed by DTDS, followed by the analysis of the tongue coating scores. Results: The tongue coating scores of the halitosis group were significantly higher than of the non-halitosis group (P=0.033). Furthermore, the difference of the posterior tongue coating between the two groups was more significant (P=0.000). Conclusions: Halitosis patients were shown to have a thicker tongue coating than those in the non-halitosis group. Moreover, the posterior dorsum of the tongue should be observed more cautiously when dealing with halitosis patients. Also, the progress and state of the patient's symptom of halitosis as diagnosed objectively by the portable gas chromatography could also possibly be analyzed instead by the DTDS tongue coating score.

Angioedema is defined as self-limited, localized swelling. The swelling is asymmetric, non-pitting, and non-tender. Common locations of swelling include periorbital area, lips, tongue, extremities, and bowel wall. A 54-year-old woman visited our hospital with the clinical complaint of left maxillary swelling. Swelling of the left maxillary area was diffuse and temperature of the involved area was normal. No infectious source was found on panoramic radiography and cone-beam computed tomography. After considering the patient's medical history and assessing clinical examination, we suspected angioedema and administered corticosteroid only. In the oral and maxillofacial area, proper diagnosis and prompt treatment of angioedema is important because angioedema of the tongue or larynx may lead to airway obstruction or a life-threatening condition.

Oral and Maxillofacial defects is produced by trauma or cancer surgery. This defects have been shown functional loss such as mastication, swallowing, speech and psychosocial esthetic problem. Oral and Maxillofacial defects is reconstructed by the use of many flaps. However although previous flap surgery was done, additional soft tissue defects can be still remained. In this case, Walk-Up flap that is introduced by Marx RE in 1990 is recommended for successful reconstruction. We report Walk-Up flap for reconstruction of remained soft tissue defects of tongue S.C.C. After induction chemotherapy, tongue S.C.C. is excised surgically and reconstructed by use of PMMC flap. Post-op infection results in surrounding soft tissue defect with oro-facial fistula. We have experienced a case of Walk-up flap by use of PMMC flap for reconstruction with satisfactory result, so we report it with literature reviews.

The piercing is increasing in western culture, and has also become gradually popular among Korean teenagers recently However, the accident hap-pens sometimes such as loss of a bar into the tongue or mouth floor during the procedure. Because of the rare cases, few treatment of choices can be made when a bar is lost inside the mouth floor. In this case, the bar was removed under fluoroscope, without giving significant damage to the adjacent structure. 18 years old female patient visited the emergency room in our hospital. She attempted to pierce her tongue herself and could not find the bar which was lost in the mouth floor. The radiographs revealed that the needle was somewhere inside the mouth floor, but if incision were to be made it would be too deep to find the bar. The bar was removed through fluoroscope easily. Primary closure was done by 5-0 Vicryl and stitch-off was done 1 week later. The patient didn't have any speech problems and complications.

Numerous investigators have pointed out that the force of the tongue against the teeth within the dental arches is normally compensated for by the action of the musculature of the cheeks and lips, and that the tongue at rest occupies a large part of the oral cavity. The purpose of this study was to estimate the maximum areas of the tongue movement by measuring the inner area of the dental arches of both the maxilla and the mandible. This study was based on the study models of 30 children and 128 adults who had clinically good occlusion. There were 15 male and 15 female children whose ages ranged from four years to seven years and 82 male and 46 female adults whose ages ranged from fifteen years to fifty four years. The obtained results were as follows : 1. The mean of the maximum areas within the primary dental arches of both the maxilla and the mandible were $7.06\pm0.8\textrm{cm}^2, 5.49\pm0.77\textrm{cm}^2$ in male children and $6.82\pm0.98\textrm{cm}^2, 5.28\pm0.80\textrm{cm}^2$ in female children respectively. 2. The mean of the maximum areas within the permanent dental arches of both the maxilla and mandible were $17.01\pm2.38\textrm{cm}^2, 13.57\pm1.57\textrm{cm}^2$ in male and $16.75\pm2.08\textrm{cm}^2, 13.36\pm1.01\textrm{cm}^2$ in female respectively.
