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.

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.

OBJECTIVES: Endoscopic prelacrimal medial maxillectomy (EPMM) was previously reported to treat maxillary inverted papilloma. This study aimed to compare prelacrimal recess approach with the conventional Caldwell-Luc approach (CLA) to remove benign maxillary sinus tumors and to evaluate the usefulness of this approach based on our experience. METHODS: Ten patients who underwent EPMM at our hospital from January 2013 to December 2017 were reviewed. We also reviewed 30 patients who underwent benign maxillary sinus tumor resection via CLA during the same period. From medical records, postoperative pathological results, complications due to surgery, and recurrence rate were evaluated. RESULTS: There were eight inverted papilloma, one ameloblastoma, and one ossifying fibroma in the EPMM group. In the CLA group, all 30 cases were inverted papilloma. There were no cases of failure at gross total removal during surgery, and no recurrences were observed during follow-up in either groups. Mean follow-up period was 13.0 months in CLA group and 10.8 months in EPMM group. Regarding postoperative complications, 11 patients of the CLA group (37%) and three patients of the EPMM group (30%) had numbness around the cheek and upper lip area after surgery (P=0.715). In the CLA group, there were eight patients who had numbness lasting more than 3 months after surgery, and two patients had numbness for more than 1 year. However, facial numbness disappeared within 3 months in all patients in the EPMM group, in which epiphora was not observed. CONCLUSION: EPMM is the effective surgical approach for resecting benign maxillary sinus tumor compared with CLA. Although facial numbness was reported in EPMM, the duration of numbness was shorter than CLA.

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.

In this report, an ameloblastoma case, which has been occurred on the left maxilla of a 10 year-old, male, German shepherd, was described on the clinical and morphological features. The mass with the dimensions of 5x2.5 cm was removed totally by maxillectomy and examined by radiography, magnetic resonance (MR) and biopsy. The tumor was histopathologically classified ameloblastoma of follicular type and in some fields showed acanthotic form. The invasiveness of the tumor was also observed to be high. This report is the first case of maxillary ameloblastoma in dogs in Turkey.

OBJECTIVETo use virtual endoscopy to obtain detailed three-dimensional images of bone, soft tissue and paranasal sinus damage as well as images of adjacent unaffected areas for optimum surgical planning.

METHODSA spiral CT scanner was used to examine 46 cases of facial bone fractures, maxillary cysts, obstructive sleep apnea syndrome (OSAS) and maxillary bone tumours. Data were input into a navigator workstation to create images similar to those displayed by a fiberoptic endoscope. Various 3-D images were obtained when probe sites were changed.

RESULTSVirtual endoscopy can clearly display the anatomic structure of the paranasal sinuses, nasopharyngeal cavity and upper respiratory tract, revealing damage to the sinus wall caused by a bone tumor or fracture. In addition, the technique can be used to indicate volume changes of the upper respiratory tract in OSAS patients. These results were similar to those obtained through actual operations.

CONCLUSIONSVirtual endoscopy is a new method which produces very clear images. It is reliable to provide detailed information for optimal operative planning.

OBJECTIVETo investigate the feasibility and safety of intraoral submandibular gland excision.

METHODSAnalyze the relationship between the external maxillary artery and submandibular gland, and offer a reliable anatomical base for 10 cases of intraoral submandibular gland excision, including 8 cases of chronic sialadenitis, 1 case of pleomorphic adenoma and 1 case of cyst of submandibular gland.

RESULTSThe external maxillary artery went across the surface of gland submandibular, and its branches provided nutrition for the gland in most cases. The results of 10 cases intraoral submandibular gland excision were effective and satisfied, without major complications. The average time of operation was 50 minutes and the average hemorrhage of operation was 60 ml.

CONCLUSIONIntraoral submandibular gland excision is safe and feasible for chronic sialadenitis and cyst of submandibular gland and some of benign tumor submandibular gland as long as indications strictly controlled and the external maxillary artery well coped with.
