  • Cleft lip and palate patients often develop maxillary retrusion due to the combined effects of the congenital deformity and the scar tissue after surgical repairs. Maxillary protraction in the cleft patients using orthopedic appliances (i.e. face mask) or distraction osteogenesis during early childhood helps to achieve more balanced skeletal harmony and favorable occlusion for future growth to occur. Kinds, indication, protocol for use of the traditional orthopedic appliances will be discussed. Also the facemask with miniplate system recently developed will be introduced.

  • Cystadenocarcinoma of the salivary glands is a very rare, slow growing, and low-grade malignant neoplasm. It is characterized by predominantly cystic growth with or without the intraluminal papillary component. However, it lacks of any additional specific histopathologic features that characterize other types of salivary carcinomas showing cystic growth. Therefore, definite diagnosis of the cystadenocarcinoma is difficult and it is often misdiagnosed. It is conceptually the malignant counterpart of the benign cystadenoma. We present a cystadenocarcinoma on the palate of a 49-year-old man with special emphasis on magnetic resonance imaging.

  • The velopharynx is a tridimensional muscular valve located between the oral and nasal cavities, consisting of the lateral and posterior pharyngeal walls and the soft palate, and controls the passage of air. Velopharyngeal insufficiency may take place when the velopharyngeal valve is unable to perform its own closing, due to a lack of tissue or lack of proper movement. Treatment options include surgical correction, prosthetic rehabilitation, and speech therapy; though optimal results often require a multidisciplinary approach for the restoration of both anatomical and physiological defect. We report a case of 56 year old male patient presenting with hypernasal speech pattern and velopharyngeal insufficiency secondary to cleft palate which had been surgically corrected 18 years ago. The patient was treated with a combination of speech therapy and palatal lift prosthesis employing interim prostheses in various phases before the insertion of definitive appliance. This phase-wise treatment plan helped to improve patient's compliance and final outcome.

  • The aim of this case report is to present a case of 68-year-old male with a history of multiple myeloma and the intravenous use of Zometa (zoledronic acid) who had developed medication-related osteonecrosis of the jaw (MRONJ) following a hot pizza burn to the palate. Clinical and radiographic findings revealed grade 1 MRONJ of the right side of the hard palate. Soft tissue trauma and delayed epithelialization may be associated with some cases of MRONJ. Patients on anti-resorptive medications or anti-angiogenic drugs should be informed of the risk of bone exposure and subsequent MRONJ secondary to physical/chemical insults to the bone and soft tissue in the oral cavity.

  • Pain on the soft palate and pharynx can originate in several associated structures. Therefore, diagnosis of patients who complain of discomfort in these areas may be difficult and complicated. Pterygoid hamulus bursitis is a rare disease showing various symptoms in the palatal and pharyngeal regions. As such, it can be one of the reported causes of pain in these areas. Treatment of hamular bursitis is either conservative or surgical. If the etiologic factor of bursitis is osteophytic formation on the hamulus or hypertrophy of the bursa, resection of the hamulus is usually the preferred surgical treatment. We report on a case of bursitis that was managed successfully by surgical treatment and a review of the literature.

  • The parents of twenty-five patients with cleft lip(with or without cleft palate), CL(P) and the parents of fifteen non-cleft patients were studied. Area measurements of cranium of brain case from lateral and frontal roentgenograms. The most important finding of this investigation was that the CL/CP parents had a significantly smaller brain case than did the control subjects. A smaller brain case may well be one morphological characteristic predisposing toward the cleft anomaly. The results obtained were as follows, 1) Total area measurements for brain case of parents of CWCP patients were significantly smaller than those in the control group, on the frontal view. 2) A significantly smaller parietal and occipital region on the frontal view vas noted in the parents of CL/CP patients. 3) A significantly smaller parietal region on the lateral view was noted in the mothers of CL/CP patients. 4) A significantly smaller mastoid area on the lateral view was noted in the parents of CL/CP patients.

EPITHELIAL-MYOEPITHELIAL CARCINOMA ARISING IN PLEOMORPHIC ADENOMA OF PALATE (다형성 선종에서 발생한 구개부의 상피성-근상피암종)

  • A case of epithelial-myoepithelial carcinoma transformed in pleomorphic adenoma occurring in palate of a 61 years old woman is reported. The tum or was composed of 2 different components, pleomorphic adenoma and epithelial myoepithelial carcinoma, accounting for approximately 40% and 60% of whole tumor, respectively. As the results of the immunohistopathologic study, epithelial-myoepithelial carcinoma showed multiple tubular or solid nest, which were separated by a basement membrane and considered of variable proportion of 2 cell types, cuboidal epithelial cells positive for cytokeratin and clear myoepithelial cells positive for glial fibrillary acid protein, wheres the myoepithelial nest of pleomorphic adenoma intermingled with hyaline and myxoid stroma. The malignancy was demonstrated by convincing evidence of invasion into the submucosa, although the epithelial-myoepithelial carcinoma component was mostly surrounded by the pleomorphic adenoma componemts. An increased immunoreactivity of proliferating cell nuclear antign in the epithelial myoepithelial carcinoma area in comparison to the pleomorphic adenoma also suggested epithelial-myoepithelial carcinoma arising in a pleomorphic adenoma.

  • The vertebrate upper lip forms from initially freely projecting maxillary, medial nasal, and lateral nasal prominences at the rostral and lateral boundaries of the primitive oral cavity. These facial prominences arise during early embryogenesis from ventrally migrating neural crest cells in combination with the head ectoderm and mesoderm and undergo directed growth and expansion around the nasal pits to actively fuse with each other. Initial fusion is between lateral and medial nasal processes and is followed by fusion between maxillary and medial nasal processes. Fusion between these prominences involves active epithelial filopodial and adhering interactions as well as programmed cell death. Slight defects in growth and patterning of the facial mesenchyme or epithelial fusion result in cleft lip with or without cleft palate, the most common and disfiguring craniofacial birth defect. This review will summarize the current understanding of the basic morphogenetic processes and molecular mechanisms underlying upper lip development.

  • The bilateral cleft lip, a more severe form of clefting than unilateral cleft lip, involves separation of the lip along philtral lines, isolating the central segment (prolabium). Bilateral cleft lip may be either symmetrical or asymmetrical, in which case the cleft lip is split more on one side than on the other. The cleft affects the obvious facial form as an anatomic deformity and has functional consequences, affecting the child's ability to eat, speak, hear, and breathe. Although there would seem to be quite a variance in reported figures, ratios of cleft lip with or without cleft palate have gone as high as 1:500 and as low as 1:1000. It is known that less than 10% of cleft lips are bilateral. Although bilateral cleft lip is less common than unilateral cleft lip, the deformity is more severe, and the reconstructive technique is more complex. Surgery is the only treatment necessary for patients with bilateral cleft lip. Accompanying the evolution of surgical repair is the increasingly important role of orthodontic support with early presurgical alveolar and nasal molding. Repositioning the maxillary and alveolar segments into a more anatomic position allows the surgeon to repair the lip and associated nasal deformity under more optimal conditions. The purpose of this article is to review the related anatomy, presurgical management, and surgical management of bilateral cleft lip.
