Malignant tumours of the oral cavity that require resection of the tongue result in severe deficiencies in speech and deglutition. In such patients, improvements in mastication, swallowing, and speech may be reasonable goals for treatment. The viability of a prosthodontic approach to treatment depends on the type and extent of surgery. In a total glossectomy, a mandibular tongue prosthesis is the treatment of choice. Mandibular tongue prosthesis occupies the space in the floor of the oral cavity. It provides the patients with a platform for directing food into the esophagus and aids in speaking. This type of prosthesis can achieve that protection of the underlying fragile tissue and improvement in appearance and psychosocial adjustment. This case report describes the technical steps involved in prosthetic rehabilitation for a glossectomy patient.

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.

If complication arises after glossectomy which leads to trouble in forming food bolus or transfer of the food, it is possible that either food bolus may block the airway or dysphagia may occur as the food bolus goes down into the airway. To solve the issue, palatal augmentation prosthesis could be used. In this case, the patient with an oral cancer is having difficulties swallowing food after glossectomy. Through taking impressions of polishing surface of his denture referring his tongue movement, the complete denture for the upper jaw was created using the concept of palatal augmentation prosthesis. This new upper denture increases the palatal-tongue contact pressure, allowing the patient to perform better swallowing and better pronunciation.

This study was carried out in order to find out the changes of the pharyngeal airway, hyoid bone and head posture before and after tonsillectomy in functional class III malocclusion patients. For this study, 21 Angle's class I patients and 21 Angle's class III patients, totally 42 subjects were chosen. The results were as follows; 1. In comparison to Class I group, tongue was more anteriorly and hyoid bone was more inferiorly positioned in functional Class III group 2. In comparison to pre-tonsillectomy, tongue was more posteriorly positioned and larger nasopharynx depth was shown in post-tonsillectomy. In post tonsillectomy, the hyoid bone was displaced posteriorly and superiorly and counterclockwise rotation was shown. 3. The level of significance for the correlation shown was 5 percent (p<0.05) indicating that: The change of nasopharyx depth was correlated to the inclination of lower incisors. Vertical change of tongue posture was correlated to the hyoid axis change. Vertical change of hyoid bone was correlated to the horizontal change of hyoid bone, craruocervical inclination. The change of craniocervical inclination was correlated to the inclination of lower incisors. 4. After the tonsillectomy, counterclockwise rotation of hyoid axis was associated with decease of hya-NL and large nasopharyngeal airway. High posture of the tongue was associated with decrease of hya-NL. Posterior posture of the tongue was associated with increase of h-hl,and decrease of hya-ba-n.

Tongue-tie is a congenital anomaly characterized by an abnormally short lingual frenum, which may restrict tongue tip mobility, In the neonate and infant, tongue-tie was said to cause difficult breast-feeding, In the older infant, toddler and young child, poor speech has been frequently listed because movement of tongue tip is limit ed. Also as a abnormal tongue position, various orthodontic problems, later mechanical and social manifestations could be developed. Treatment options such as observation, speech therapy, frenotomy and frenectomy have been suggested. The optimal timing for the surgery has not been determined, but early intervention may be appropriate for the children with significant tongue-tie who has the significant potential to speech difficulties and later social and mechanical problems. Sedation is an effective method for incapable of cooperative and the handicapped children, necessary to early intervention. We report three cases, using oral sedation for the frenectomy in young children with severe tongue-tie. After treatments, we could find out sufficient tongue movement and improved speech ability.

The tongue, especially its lateral part, is the most common site of oral tumors. Patients who undergo glossectomy for the treatment of tongue cancer may experience difficulty in proper functioning for pronunciation, chewing, swallowing, and oral hygiene maintenance; therefore, a palatal augmentation prosthesis can be used to restore function of the tongue. In this case, an implant overdenture was used in a patient who had residual ridge resorption and obliteration of alveololingual sulcus after undergoing glossectomy for tongue cancer treatment. In addition, a palatal augmentation prosthesis with a metal framework, support, and retention part was fabricated. The palatal vault was reduced, so that even with limited tongue movement, adequate tongue-palate contact could be achieved. After placement of the definitive prostheses, the patient showed improvement in the functions of chewing, swallowing, and pronunciation.

Macroglossia can cause dentomusculoskeletal deformities, instability of orthodontic and orthognathic surgical treatment, and create masticatory, speech and airway management problems. To determine whether a reduction glossectomy is necessary, it will important to identify the signs and symptoms of macroglossia. Development of dentoskeletal changes directly related with tongue size, such as an anterior open bite or a Angle Class III malocclusion tendency, would indicate that reduction glossectomy may be beneficial. For reduction glossectomy, several techniques have been reported. However, in most techniques the tip of tongue is removed. So its excision causes the loss of most mobile and sensitive portion of the tongue, and creates ankylosed, globular tongue. To avoid such problems, central tongue reduction technique have been proposed. This article will introduce central tongue reduction for anterior openbite case associated with macroglossia.

Lymphangiomas are relatively rare benign tumors of the lymphatic system, characterized by congenital lymphatic malformation such as anastomosis or obstuction of the lymphatic channels. There are most frequently diagnosed in children younger than 3years. In contrast to that of the hemangioma, the sex distribution of the lymphangioma is nearly evenly divided. The head and neck lymphangioma represents about $70{\sim}75%$ of all lymphangiomas, and they are difficult to manage. Spontaneous regression is rare, and rapid intermittent enlargement occurs secondary to infection or trauma. Enlargement may cause serious sequelae such as airway obstruction, feeding difficulties, and cosmetic problems. Treatments previously used for lymphangiomas include surgical excision and intralesional injection of sclerosants. Problems associated with surgical excision include the risk of cosmetically unacceptable scarring and the risk of damage to surrounding vital stricture and the high risk of incomplete excision. The sclerosants previously used have numerous other local and systemic side effects. This report describes a case that was successfully treated using OK-432 as a new sclerosant drug and secondary surgical excision for congential cavenous lymphangioma extensively enlarged to tongue, mouth floor and submandibular region.

Tumors originated from peripheral nerve tissues are neurofibroma, neurilemoma, plexiform neurofibroma, malignant schwannoma, and granular cell tumor. Neurofibromas seem to occur in two forms : The first one is circumscribed solitary neurofibroma and the second group is neurofibromatosis or Von Recklinghausen's disease, which is a congenital and familial disease, presenting abnormalities of the skin, nerve system, bones and soft tissue. A solitary neurofibroma is a benign, relatively circumscribed, noncapsulated tumor which often presents in the skin and subcutaneous tissue as a soft sessile or pedunculated mass. It may occur anywhere in the head and neck, but the common site of the occurrence is the tongue, buccal mucosa, palate in frequency. Since solitary neurofibroma is a relatively radioresistant and its recurrence rate seem to be low, the treatment of choice is surgical excision. The author would like to present a case of unusually large solitary neurofibroma occured in the chin, which was successfully treated with surgical excision and reconstructed using deltopectoral flap and tongue flap.

There are a number of situations where the oral mucosa can be sucked or pressed to produce relatively banal but clinical distinctive changes. The labial and buccal mucosa and tongue may develop protuberances in areas where a tooth is missing or extra space is present. The mucosa is pressed and sucked into these spaces, thus leading to the development of a fibrous hyperplasia. This case report describes the management of fibrous hyperplasia in oral mucosa. Fibrous hyperplasia can be formed by habitual pressure or suction in oral mucosa. Treatment of fibrous hyperplasia consists of simple excision and, if feasible, elimination of the cause. And habit control is a important factor for preventing recurrence.
