The records of 18 patients with squamous cell carcinoma of the tongue and floor of mouth treated surgically were reviewed. Surgical approaches, staging, treatment modalities, recurrence and vital status were evaluated. The distrubutions of involved sites were tongue(9 cases) and mouth floor(9 cases). Patients were treated by surgery primarily, combined chemotherapy and radiation, and by surgical salvage in the failure cases of radiation and chemotherapy. All ipsilateral necks of mouth floor cancer and advanced tongue cancer were treated with neck dissection. Cases of early tongue cancer could be excised with transoral route, and advanced cases needed transmandibular approach. Whereas, majorites of mouth floor cancer needed transmandibular approach, and other cases could be excised transoral and pull-through approaches. In the recontructions, we used primary closure, pectoralis major myocutaneous flap, forearm free flap, fibular osteocutaneous flap and skin graft. One year survival rate was 93% and 2 year survival rate was 60%.

Epidermal cyst in the floor of mouth is relatively rare disease. Patients usually present soft and non-tender mass at the midline of mouth floor. Careful history taking and imaging study are needed for the diagnosis and surgical excision is the choice of treatment. We report a case of huge epidermal cyst located in the floor of mouth mimicking plunging ranula, which was successfully removed by transoral surgical excision without any complication. It was diagnosed as an epidermal cyst by pathologic examination.

Background : Important factors to determine treatment method and prognosis of oral cancer are anatomical site, tumor size, metastatic lesion, histologic cell differenciation and microvascular invasion. Anatomical site has great effect to oral cancer patient's survival rate because each site's accessibility and lymph node metastasis is different but this factor was't studied much than other factors. Patients and Methods : 228 patients with squamous cell carcinoma of common primary sites(Mandible, Maxilla, Floor of Mouth and Tongue) in oral cavity who were diagnosed in the Korea Cancer Center Hospital from January 1989 to December 1999, were clinically studied and analyzed on survival rate. Results : 1. Survival rates of each anatomical sites were Tongue(36.8%), Mandible(33.3%), Maxilla(28.7%) and Floor of Mouth(24.5%). Survival rates difference between Tongue and Floor of Mouth has significance(p<0.05). 2. Survival rates for early cancer of each site were Maxilla(100%), Mandible(57.1%), Tongue(54.2%) and Floor of Mouth(46.7%). Survival rates difference between Maxilla and Floor of Mouth has significance(p<0.05). 3. Survival rates by surgery method of each site were Maxilla(60.6%), Tongue(56.9%), Mandible(44.8%) and Floor of Mouth(26.3%). Survival rates difference between Maxilla and Floor of Mouth has significance(p<0.05). 4. Survival rates by radiation or chemo method of each site were Floor of Mouth(23.5%), Mandible(20.0%), Maxilla(9.5%), and Tongue(9.1%). Survival rates difference between each site doesn't have significance(p>0.05). 5. In advance stage, Survival rates by single therapy of each site were Tongue(33.6%), Mandible(23.5%), Floor of Mouth(16.7%), Maxilla(0%), and Survival rates difference between Maxilla and Tongue has significance (p<0.05). Survival rates by combination therapy of each site were Mandible(38.1%), Maxilla(30.0%), Floor of mouth(18.2%), Tongue(12.5%), and Survival rates difference between Mandible and Tongue has significance(p<0.05). Conclusion : Survival rate of tongue is higher than the other sites, early detection of oral cancer can increase survival rate at any site and combination therapy is the most effetive method, especially at maxilla.

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.

Dermoid cyst is a benign neoplasm, so called by teratoma that is derived from both ectoderm and mesoderm during embryonic period. The majority of dermoid cysts are found in the ovaries and approximately only 7% of dermoid cysts are found in the head and neck. The growth of dermoid cysts in the floor of the mouth is considered a rare condition. We report one case of huge dermoid cyst in the floor of mouth suffered with double chin appearance and difficulty in pronunciation and respiration. The cyst was excised successfully only intra-oral incision. Clinical progress was uneventful and postoperative recovery excellent without recurrence.

Lipoma is one of the most common benign tumors in the human body. However, they are uncommon in the oral cavity. Oral lipomas can occur on the cheeks, tongue, lips, gums and rarely on the floor of the mouth. Clinical symptoms are usually asymptomatic yellow masses. Sometimes the tumor grows and can have difficulty speaking and mastication. The treatment of lipoma is surgical excision, and recurrence is rare. We present a case of oral lipoma in an unusal location on the floor of mouth which is rare in the literature.

Most neoplasm of the floor of the mouth are squamous cell carcinoma. They originate from anterior midline floor of the mouth and penetrate into the sublingual gland. Invasion of the mandible is a late manifestation. Lymphatic spread is the submaxillary and subdigastric nodes and advanced lesions of them produce severe pain, The initial step in managing patients with cancer pain is the oncology therapy in the form of radiotherapy, surgery, or chemotherapy, alone or combined. When oncologic therapy is ineffective, the pain must be treated by systemic analgesic, psychologic, neurostimulating, regional analgesic,and meuroablative techniques. We successfully treated with gasserian ganglion block on the left side and mandibular nerve block on the right side with pure alcohol in the patient having severe submandibular, lower lip and tongue pain.

Dermoid cyst of the floor of mouth is infrequent. This cyst has been classified as epidermoid, dermoid and teratoid cyst. Dermoid cyst is more common in young adults and no sex predilection and has generally been present for months to years before progressive enlargement causes interference with the mobility of the tongue and disturbance of articulation and mastication. The authors have recently experienced dermoid cyst of the floor of mouth which was confirmed histopathologically.

Dermoid cysts located in the floor of the mouth are very rare developmental keratinizing squamous epithelium lined cysts. Anatomically, they are classified as sublingual (median genioglossal), submental (median geniohyoid) and lateral dermoid cysts, and they can be further classified as epidermoid, dermoid, and teratoid cysts by histology. We report a case of sublingual dermoid cyst in a 16-year-old boy presenting as a large sublingual swelling causing speech and swallowing difficulties and discuss the surgical treatment techniques and histopathological features of this lesion.

The author has diagnosed and treated the dermold cyst patient in the 41 years old korean man. The dermold cyst in the floor of the mouth had various sign and symptom such as elevated tongue, disturbance of speech and swallowing, and etc. The cyst wall of dermoid cyst was enucleated by using of direct enucleation of cyst wall and primary suture technique. The mass of the enucleated dermoid cyst was 5×5.5×6 Cm.in size.
