11/33. Metastatic cancer to the floor of mouth: the lingual lymph nodes.BACKGROUND: The upper level of a cervical lymphadenectomy is anatomically defined at its anterior extent by the lower border of the mandible and, in surgical practice, by the lingual nerve. A neck dissection completed below this level is generally considered adequate for removal of lymph nodes at risk for metastases from oral cavity cancer. Traditional discontinuous neck dissections do not provide for removal of floor of mouth tissue along with the primary and neck specimens. methods: A case report presenting biopsies from a T2N2bM0 squamous cell carcinoma of the mobile tongue and adjacent floor of the mouth in a 73-year-old man. RESULTS: Deep biopsy of a ventral tongue and floor of mouth squamous cell carcinoma revealed occult metastatic cancer to lymph nodes located in the superficial floor of mouth associated with the sublingual gland above the lingual nerve. This report identifies floor of mouth lymph nodes that can be involved with cancer and missed through the standard practice of discontinuous neck dissection.Conclusions. This finding offers evidence that, in certain cases, a traditional discontinuous neck dissection may not address all lymph nodes at risk in the treatment of oral cavity cancer. Further investigation into lymph node distribution within the oral cavity is warranted to reappraise the upper limits of cervical lymphadenectomy.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
12/33. Massive bleeding from an ectopic lingual thyroid follicular adenoma during pregnancy.Ectopic thyroid is a rare developmental anomaly. It can be found anywhere between the foramen cecum and the normal position of the thyroid gland. Massive bleeding from an ectopic lingual thyroid is unusual and occasionally fatal. We present a case of a 22-year-old woman who had a large mass at the base of the tongue for over 6 years. In the sixth month of pregnancy, the patient experienced massive bleeding from the tongue base mass. A thyroid scan revealed that this mass was the only functioning thyroid tissue. Because of massive bleeding and her shock status, the patient received an emergent embolization of the bilateral lingual arteries. Then the huge lingual thyroid was subsequently excised via a mandible swing approach to prevent further episodes of bleeding. pathology analysis indicated ectopic thyroid tissue with follicular adenoma. She delivered without complications in the 36th week and had a normal baby. This case was a very rare one in our review. Although ectopic lingual thyroid usually is not managed surgically, excision of ectopic lingual thyroid can be life-saving when it is causing bleeding or airway obstruction.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
13/33. liposarcoma circumscriptum (lipoma-like) of the tongue: report of a case.liposarcoma, first described by Virchow in 1857, is the second most frequent sarcoma of soft tissues, although it is rare both in the head and neck and the oral cavity. Intra-orally, liposarcoma has been reported in the jawbones (particularly the maxilla) and the soft tissues -- mainly the cheek and floor of mouth, but it is rare in the tongue. A case of well-differentiated, superficial liposarcoma circumscriptum of the tongue is reported. The authors underline the difficulties in the clinical and histopathological diagnosis, as this tumour may be confused with lipoma. In view of the indolent behaviour of this tumour type, local recurrence or metastasis rarely occur; consequently, conservative surgical therapy is advised without adjuvant chemo-radio therapy.- - - - - - - - - - ranking = 0.021853415093825keywords = jaw (Clic here for more details about this article) |
14/33. Mandibular restoration in the cancer patient: microvascular surgery and implant prostheses.This article deals with state of the art reconstruction and rehabilitation of the head and neck cancer patient who requires mandibular resection. The mandible can be reconstructed by microvascular free tissue transfer of bone and soft tissue from distant body sites. The dental units and missing soft tissue contours can be supported by osseointegrated implants placed in the grafted bone. This article discusses the rationale for patient selection and sequencing of this complex and rewarding rehabilitation.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
15/33. granular cell tumor of the tongue in a 6-year-old girl--a case report.granular cell tumor is a relatively uncommon benign hamartomatous lesion occurring in almost any part of the body. The tongue and the buccal mucosa are common intra oral sites. Granular cell lesions may be found in other diverse sites such as the jaw, skin, gastro intestinal tract and respiratory tract. The histogenesis of the lesion still remains unknown. However, histochemical and ultra structural studies propose the origin of the lesion from schwann cells, striated muscle, mesenchymal cells, histiocytes and epithelial cells. The tumor generally occurs in middle or older aged adults. The lesion is typically seen as an uninflammed asymptomatic mass measuring about two cms in diameter with a yellowish surface coloration. As most of the granular cell tumors are benign, surgical excision of the lesion is the treatment of choice. We describe a case of granular cell tumor of the tongue in a 6 year old girl along with a brief review of literature on granular cell tumors.- - - - - - - - - - ranking = 0.021853415093825keywords = jaw (Clic here for more details about this article) |
16/33. Implant-retained overdenture following hemiglossectomy: a 10-year clinical case report.A clinical evaluation of an implant-supported overdenture placed in the edentulous mandible after hemiglossectomy is described. The deltopectoral flap covering the mandibular ridge was replaced with a free mucosal graft. Four Branemark system implants were inserted into the anterior part of the mandible, but one of the four fixtures did not show osseointegration. The superstructure was designed as a spaced round bar-attachment supported by three implants so as to retain the complete overdenture. In addition to the metal clip, a silicone-based soft denture liner material was applied in the female portion of the attachment so as to prevent the attachment from making a clattering noise upon mastication. Although the overdenture required adjustment at regular intervals, the treatment was successful both aesthetically and functionally for up to at least 10 years.- - - - - - - - - - ranking = 2keywords = mandible (Clic here for more details about this article) |
17/33. Prosthetic rehabilitation with HA-coated root form implants after restoration of mandibular continuity.Utilization of implants to aid in oral reconstruction after partial mandibular resection entails coordination of multiple health care co-therapists as well as funding sources for the underprivileged. An illustrative case emphasizes these points. Ablation of a squamous cell carcinoma of the tongue resulted in a partial mandibulectomy, as well as multiple sensory, physical and psychosocial deficits. Continuity of the mandible was restored with a vascularized iliac crest bone graft. (Fig. 1) Total functional restoration, however, was only possible with implant supported overdenture prostheses.

18/33. lymphangioma of the tongue and the team approach.Case report of a 9-year-old female with a 7cm (length) x 4cm (width) x 1cm (thick) lymphangioma of the tongue. The tumor caused speech distortion, crowding of the anterior maxillary and mandibular teeth, and a prognathic mandible. The patient was evaluated by the members of the cleft lip and palate Team at St. Christopher's Hospital and underwent a complete resection of the tumor and is continuing follow-up care. This case exemplifies the value in a team approach to a variety of intraoral problems.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
19/33. Thoracic malignant fibrous histiocytoma metastatic to the tongue and skin of the face.A 60-year-old white man was found to to have metastatic malignant fibrous histocytoma in the tongue and facial skin 15 months after diagnosis of the primary lesion in the thorax. This is believed to be only the fourth reported case of this tumor metastatic to the oral cavity and the first lingual metastasis from outside the jaws.- - - - - - - - - - ranking = 0.021853415093825keywords = jaw (Clic here for more details about this article) |
20/33. Metastatic carcinoma to the tongue: a report of two cases and a review of the literature.Metastatic tumors of the oral cavity are uncommon. Most of them are located in the mandible while only a small percentage are found within the soft tissues. Two cases of metastatic bronchogenic carcinomas to the tongue are described. review of the literature showed that cancer of the lung was the most common primary lesion that metastasized to the soft tissues of the oral cavity. The base of the tongue was the most prevalent site of metastases to soft tissue within the oral cavity.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
