Retention cyst of the maxillary sinus is a benign lesion produced from obstruction of a seromucous gland or duct. It is mostly asymptomatic but sometimes is accompanied by facial pain, headache, nasal obstruction, and other symptoms. However, there are some debates on whether the symptoms are directly related with retention cyst. These cysts typically do not require treatment. However, when accompanied by symptoms, treatment can be administered for diagnostic and therapeutic purposes. We report a case in which facial pain is caused by a maxillary retention cyst suspended from an infraorbital nerve.

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.

Causes of syncope are manifold. Hypersensitive carotid sinus reflex is a cause of syncope and other bradycardia symptoms. Rarely, maxillary neoplasms can cause carotid sinus syncope. The authors identified a case of carotid sinus syncope by maxillary neoplasm accompanied by vasovagal syncope.

The clinical manifestations of the disease lacked specificity,and the clinical symptoms were nasal obstruction, any blood in snively and slightly swelling pain on face. The neoplasm with unsmooth surface looked taupe and maroon, and was brittle and easy blooding. Paranasal sinus CT:crumbly mass lesion within the shadow filled in the left side of the maxillary sinus,and the sinus stopped up,sinus wall bone was absorpt and thinned, front and rear wall and inner wall bone were boundedness broken off, knuckle partly to the nasal cavity. Direct reinforcement MRI:in addition to the result of paranasal sinus CT,enhance examination found obviously asymmetrical intensify of the focus. The pathological diagnosis of postoperation was malignant melanoma on the left side of the maxillary sinus.

PURPOSE: Maxillary sinus cancers are usually locally advanced, and involve the structures around sinus, but the regional lymphatic spread is uncommon. Therefore, the local control of these cancers is important for their cure. We reviewed our experience of 55 patients with squamous cell carcinomas of the maxillary sinus, treated with radiation therapy, and looked for the role of radiation therapy in maxillary sinus cancers. MATERIALS AND METHODS: Between November 1982 and October 1999, 55 patients with squamous cell carcinomas of the maxillary sinus underwent either radiation therapy only, or combined with surgery or with concurrent chemoradiation therapy. All patients were restaged according to the 1997 AJCC staging systems. The T classifications of the tumors of the patients were as follows:1.8% (1/55) for T2, 81.8% (45/55) for T3 and 16.4% (9/55) for T4. Thirteen patients were diagnosed with lymph node involvement. With the surgical procedures, 12 patients were managed by biopsy only, 21 were resected by FESS (functional endoscopic sinus surgery) and 22 by partial/medial/total maxillectomies. The details of the treatments were as follows:8 patients were treated with radiation therapy only, 17 with a combination of FESS and radiation therapy, 22 with a combination of a maxillectomy and radiation therapy, 4 with a combination of preoperative radiation therapy and surgery, and 4 with concurrent chemoradiation therapy. The mean follow-up for all patients was 25 months, ranging from 2.8 to 125 months. RESULTS: The 4-year local control and survival rates for all patients were 45.5 and 33.3%, respectively. The 4-year local control and survival rates, due to the extent of surgery, were as follows:32.1, and 21.4 % for biopsy; 41.9, and 31.7% for FESS; and 56.8, and 52.7% for maxillectomy, respectively. Twenty-nine (52.7%) patients were not cured, and of these 29 patients, 23 (79.3%) patients had a local recurrence following treatment. CONCLUSION: This study has shown that the major failure sites following treatment to be the local regions, and that the completeness of surgery was important for improving the local control and survival of patients with squamous cell carcinoma of the maxillary sinus.
