The authors have observed a case o hemangioendothelioma occurred on the left palate and buccal mucosa of a 40 year old woman. The results are as follows. 1) A blue-red round mass, 1.0cm in diameter, appeared on the palate and a blueviolet oval mass, 1.2cm in diamcter, on he buccal mucosa, and both of them showed a tendency to bleed after even slight trauma. 2) Microscopically the lesion was composed predominantly of masses of endothelial cells proliferating in and about the undifferentiated vascular channels. 3) well-vascularized tissue was made up of vascular spaces, showing infilitration of small round cells.

저자들은 1977년부터 1986년까지 10년동안 서울대학병원 이비인후과에서 유년기성 비인강 혈관섬유종의 진단하에 치료받았던 27명의 환자에 대해 임상적 조사를 시행하여 다음과 같은 결과를 얻었다. 1) 남녀비율은 전례에서 남성이었으며 연령은 9세∼22세의 분포를 보였고 16∼17세가 가장 많았다. 2) 주증상으로는 전례에서 비출혈을 동반하는 비폐색증을 보였으며 편측인 례가 7례였다. 3) 종양의 크기는 21례에서 비인강 및 비강내에 국한되어 있었고, 4례에서 익상상악와, 2례에서 두개내 침습을 보였다. 4) 종양의 혈액공급은 동측의 내상악동맥에서 이루어지는 경우가 27례, 동측의 상행인두동맥이 13례, 양측에서 이루어지는 경우가 9례 있었다. 5) 치료는 23례에서 수술적 요법을, 4례에서 방사선치료를 시행하였다. 수술적 요법 23례중 11례 에서 경반구개제거술(hemipalatal approach), 8례에서 경전구개제거술(transpalatal appoach), 2례에서 경전구개 및 경상악동제거술(transantral approach), 2례에서 외비절제술(lateral rhinotomy approach)에 의해서 종양을 적출하였다.

Craniofacial sutures absorb the stress transferred to skull. It was reported the cells of craniofacial sutures respond to exogenetic factors to be involved in growth control mechanism. In this study, we constructed a finite element model composed of cortical bone, cancellous bone, suture, PDL, and teeth by using CT images of a growing patient, simulating maxillary expansion to evaluate the effects of the thickness of sutures and type of maxillary expansion appliance on stress distribution in circummaxillary sutures.

A 5-year-old intact female mixed dog was admitted to the Veterinary Teaching Hospital for reconstructive surgery of traumatic oronasal communication in the palatal region after suffering a facial gunshot injury. The surgical procedure involved making buccal mucosal flaps as well as a transposition flap of the hard palate mucoperiosteum from the tissue adjacent to the defect, followed by applying a prosthetic appliance to protect the surgical flaps. A satisfactory outcome was obtained using a palatal prosthesis.

It was said that early rapid palatal expansion was the treatment of choice in case of maxillary constriction with posterior crossbite. The author tried to assess dimensional changes of nasal and oral cavity before rapid palatal expansion and over 4 months of retention by use of three coronal tomograms through the incisal, molar, and maxillary tuberosity areas. The subjects of this study were consisted of 9 boys and 11 girls ranging from 11 to 13 years old. The results were as follows: 1. A mean change in maxillary first molar width was 3.68mm and a mean change in nasal cavity width was 2.26mm after 6.70mm expansion by Hyrax-type screw and over 4 months of retention tomographically in molar cut. 2. A change in nasal cavity width tomographically showed in order of molar cut, incisal cut, maxillary tuberosity cut respectively. 3. There was no correlation between changes in oral cavity width and nasal cavity width.

Pleomorphic adenoma is a benign salivary gland tumor with histologic diversity. The majority of these tumor occurs in the parotid gland. The authors experienced the patients, who complained the tumor-like soft tissue mass on the palatal area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed it as pleomorphic adenoma in the palatal area, and obtained characteristic features were as follows: 1. Main clinical symptom was a painless, slow growing, soft tissue mass with normal intact overlying mucosa on the palatal area. 2. In the radiographic examminations, well encapsulated homogeneous soft tissue mass was shown in the lesion site, and cortical thinning on the palate was also observed. 3. In histopathologic examminations, proliferated cellular components in the hyaline stroma were observed as double layered duct-like structure and densely solid sheet appearance.

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.

Ten cleft palate patients were operated with reconstruction of levator sling without pushback for the purpose of not to make raw surface in the anterior portion of hard palate to prevent maxillary retrognathia. Speech was evaluated by using speech assessment list. Maxillary growth was not evaluated due to in-growing age in majority patient. The report will be followed in next chance. We could impose the significance in clinical application of levator sling palatoplasty without any complications but improving speech.

This study was designed to investigate the treatment, generalization, and maintenance effects of vocal relaxation treatment on compensatory articulation(i.e., glottalization of plosive sound) of three children with cleft palate. Multiple baseline design was applied to evaluate treatment, generalization, and maintenance effects. The targeted phonemes were ph/, th/, /t/ which Were frequently substituted by glottal stop sounds. The main component of the treatment program was vocal relaxation using humming and aspiration sound /h/. The following conclusions were deduced from the results: (1) the treatment program for compensatory articulation was effective in facilitating correct production of targeted phoneme and eliminating glottalization for all subjects, (2) the treatment effects on articulation accuracy were generalized to untreated phonemes (/c/, /c$c^{h}$/) for 2 subjects, (3) the treatment effects on decrease of glottalization were generalized to untreated phonemes for all subjects, and (4) the treatment effects were maintained for all subjects for 2 weeks after treatment was terminated.
