Cystadenocarcinoma Arising in the Oral Floor, A Case of Effective Use of Fine-Needle Aspiration Cytology and Biopsy

Cystadenocarcinoma is a rare malignant tumor characterized by predominantly cystic growth, often with intraluminal papillary growth. Cystadenocarcinoma of the salivary gland lacks the additional specific histopathologic features that characterize other types of salivary-gland carcinomas with a  cystic growth pattern. 

Cystadenocarcinoma Arising in the Oral Floor

Cystadenocarcinoma occurs most commonly in the parotid gland and in people over 50. Involvement of the sublingual gland is proportionately greater than with other salivary gland tumors, whether benign or malignant. Of the minor salivary gland sites, cystadenocarcinoma most frequently involves the buccal mucosa, the lips, or the palate, and it rarely arises in minor salivary glands in the oral floor. We here report a rare case of cystadenocarcinoma arising from a minor salivary gland in the oral floor, and the effective use of fine-needle aspiration cytology (FNAC) and biopsy (FNAB) in obtaining a preoperative diagnosis.

Harvesting Free Palatal Masticatory Mucosal Graft Using 3a Mucotome

Image
The technique of free autogenous gingival grafting (FGG) has undergone little modification since its introduction by Bjorn in Scandinavia in 1963 and by King and Pennel inthe United States in 1964. The technique is widely used to treat a variety of mucogingival problems such as insufficient or lack of attached gingiva, the presence of high frenum attachments, shallow fornix and denuded roots following gingival recession.  FGG can be procured from donor site using scalpels, gingivectomy knife or palatal shaving knife (Paquette knife). The donor site is frequently the palate, although the use of edentulous ridge areas, tuberosity and attached gingiva has also been described. Scalpel is most commonly used and conventional method for procuring gingival auto grafts. Gingivectomy knife, although not commonly used, also works on similar principle. Since the scalpel blade is straight and stiff and the palate is curved, repeated incisions to release the graft from underlying conn...

Indications for Orthognathic Surgery

Image
Orthognathic surgery (OS) is a surgical intervention that alters relationships of the jaws and dental arches. The treatment involves a combination of orthodontics and maxillofacial surgery.  Orthognathic Surgery It is used to correct dentofacial deformities that cannot be treated with acceptable results by conventional orthodontics. The first description of a surgical intervention to correct a malocclusion was by Hullihen in 1849. The most frequently used surgical procedures for correcting the relationship of the jaws are Le Fort I osteotomy and sagittal ramus split osteotomy. Also often used are vertical ramus osteotomy, inverted L osteotomy, and variations and combinations of the above. Read More>>>>>>

Micro-Implant Anchorage for Orthodontic Treatment of Bialveolar Protrusion

Image
Conventional methods of reinforcing orthodontic anchorage have several disadvantages, including complicated appliance design and the need for exceptional patient cooperation. Kanomi and Costa et al.   introduced the use of titanium microscrews and miniscrews for orthodontic anchorage. Microscrews are small enough to place in any area of the alveolar bone, easy to implant and remove, and inexpensive.    In addition, orthodontic force application can begin almost immediately after implantation. In particular, microscrews have been shown to produce en masse retraction of the six anterior teeth. So it was decided to use micro-implants to treat a patient having Class 1 bialveolar protrusion where anchorage demands are critical. The patient, a 15-year-old female, had a convex profile and a Class I skeletal pattern with bialveolar protrusion Cephalometric analysis showed an ANB angle of 4°, a mandibular plane angle (FMA) of 20° and facial angle of 88°.
