94 patients who were 15 years or more were involved in study. These patients were underwent histological examinations. Histopathological revealed variable and complex lesions, with multiple lesions in the same sinus such as mucous degeneration, hyperplasia, dysplasia, atrophy, papiloma, fungus. Lesions in buffer tissues include significant edema, bleeding, congestion, gland proliferation and structural abnormalities.

Regeneration of maxilary mucosa were seen in 14/20 patients with ages of 6 months -5 years after Caladwell- Luc operation. Contrary, the persistance of naso- antral window in the inferior meatus was only seen in 1/20 patients. In most of cases, this window is partial or total obliterated. An improve is proposed by the authors: - A small nasoantral creating window in the inferior meatus. - Preserve the mucosa at this window. - Enlarge the natural maxilary ostium.

2 patients received the microsurgical flap. Both flaps has been living well, the functions were recovered well. The shape of face was relatively equal. The patients received a false maxila and teeth. The moving functions of the leg donated the calcaneal bone were well recovered without influencing the life. The conclusion: the defct of facio-maxillary area is a major lession that should be treated. The technique of microsurgery with using the calcaneal bone flap helps reconstructing the facio-maxillary area.

Laser surgery and medicine were considered as one of the topic of mordern medical technologies and has been widely applied in the various medical fields. We have been using CO2 laser in maxillofacial surgery for 506 patients at Khanh Hoa provincial general hospital, since Feb 1994. Result: good: 93.08%, medium: 5.33%. Poor: 1.58%.

Study on nursing caries syndrome of 197 children aged 2-3 years old in the kindergartens, located in districts, Ho Chi Minh city. 9.6% child were diagnosed as having nursing caries (at least one of the maxillary incisors having labial caries or/and erosion). 3 dietary factors, nocturnal bottle feeding, comforters, coated with sweeteners and use of fuices in the feeding bottle were found significantly associated with nursing caries. There was no significant characteristic with the exception birth order of the child, where the condition was significantly higher in the first born children as compared to the later issues of their parents

PURPOSE: Maxillary sinus cancers usually are locally advanced and involve the structures around sinus. It is uncommon for this cancer to spread to the regional lymphnodes. For this reason, local control is of paramount important for cure. A policy of combined treatment is generally accepted as the most effective means of enhancing cure rates. This paper reports our experience of a retrospective study of 31 patients treated with radiation therapy alone and combination therapy of surgery and radiation. MATERIALS AND METHODS: Between July 1974 and January 1992, 47 patients with maxillary sinus cancers underwent either radiation therapy alone or combination therapy of surgery and radiation. Of these, only 31 patients were eligible for analysis. The distribution of clinical stage by the AJCC system was 26%(8/31) for T2 and 74%(23/31) for T3 and T4. Eight patients had palpable lymphadenopathy at diagnosis. Primary site was treated by Cobalt-60 radiation therapy using through a 45degree wedge-pair technique. Elective neck irradiation was not routinely given. Of these 8 patients, the six who had clinically involved nodes were treated with definite radiation therapy. The other two patients had received radical neck dissection. The twenty-two patients were treated with radiation alone and 9 patients were treated with combination radiation therapy. The RT alone patients with RT dose less than 60 Gy were 9 and those above 60 Gy were 13. RESULTS: The overall 5 year survival rate was 23.8%. The 5 year survival rate by T-stage was 60.5% and 7.9% for T2 and T3, 4 respectively. Statistical significance was found by T-stage (p<0.005). The 5 year survival rate by N-stage was 30% for N(-) and 8.3% for N(+), but statistically no significant difference was seen(p30.1). The 5 year survival rate for RT alone and combination RT was 22.5% and 27.4%, respectively. The primary local control rate was 65%(20/31). CONCLUSION: This study did not show significant difference in survival between RT alone and combination RT. There is still much controversy with regard to which treatment is optimum. Improved RT technique and development of multimodality treatment are essential to improve the local control and the survival rate in patients with advanced maxillary sinus cancer.

Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign reactive vascular lesion, characterized by thrombus formation and subsequent intravascular endothelial proliferation. IPEH should be differentially diagnosed from angiosarcoma because of their microscopic similarity. The clinical manifestation of IPEH varies according to involved site. We report a rare case of IPEH in the maxillary sinus of 35-year-old male presenting with epistaxis, which is completely removed without complications.

BACKGROUND AND OBJECTIVES: Although sinusitis is commonly caused by nasal diseases that interfere with ostiomeatal unit, non-rhinogenic sinusitis, for example, post-traumatic or odontogenic, is often encountered. However, it remains unclear whether non-rhinogenic sinusitis affects the function and morphology of the nasal mucosa. The aim of the current study is to observe effects of experimentally induced maxillary sinusitis on ciliary beat frequency and histopathology of the nasal mucosa in rabbits. MATERIALS AND METHOD: Maxillary sinusitis was induced in the right sides of 10 rabbits by partially occluding the natural ostia and inoculating the maxillary sinus with P. aeruginosa. After 4 weeks, the nasal mucosa was obtained from the inferior turbinate and the septum in the right (experimental group) and the left side (control group A). Both sides of the nasal mucosa in another 5 normal rabbits were used as the control group B. Ciliary beat frequency (CBF) was measured by video-computerized analysis and degree of inflammation in histopathology was graded using a 100-point scale of inflammation score. CBF and inflammation score were compared between the three groups. RESULTS: CBFs of the experimental group were significantly lower than those of the control groups A and B. Inflammation scores of the experimental group were significantly higher than those of the control groups. In the experimental group, there were no correlations between CBFs of the maxillary and nasal mucosa, but weak correlations existed between inflammation scores of the maxillary and nasal mucosa. CONCLUSION: Primary maxillary sinusitis can locally induce dysfunction and inflammation of the nasal mucosa.

Maxillary sinusitis is an infectious disease which can arise from odontogenic etiology and a maxillary osteomyelitis can spread into the sinus and consequently develop maxillary sinusitis. In this case report, a mid eighty's lady was diagnosed as BRONJ with maxillary sinusitis as a complication. The patient was managed successfully in collaboration with a endocrinologist. Through serial follow-up of serum CTX, we could decide the timing of surgical intervention.
