BACKGROUND AND OBJECTIVES: There are various subtypes in lymphoma of the nasal cavity and paranasal sinuses. This study aimed to compare the clinical differences between NK/T cell lymphoma and B cell lymphoma in the nose and paranasal sinuses. MATERIALS AND METHODS: From 1991 through 2003, 18 patients were diagnosed with lymphoma by histopathologic biopsy (NK/T cell 13 : B cell 5). We reviewed the medical records retrospectively regarding subjective symptoms, physical findings, and PNS CT findings. RESULTS: The most common symptom of NK/T cell lymphoma was nasal obstruction (8/13), and the main endoscopic finding was ulcerative small lesion. The PNS CT finding of NK/T cell lymphoma was homogenous, poorly enhanced, small mass. In contrast, the most common symptom of B cell lymphoma was periorbital swelling (2/5), and the main endoscopic finding was fungating mass. The PNS CT finding of B cell lymphoma was heterogenous, well-enhanced, large mass with bone destruction. The location of NK/T cell lymphoma was the inferior or middle turbinate in the nasal cavity, whereas the location of B cell lymphoma was the ethmoid or maxillary sinus. CONCLUSION: It is suggested that there may be significant clinical differences between NK/T cell lymphoma and B cell lymphoma in the sinonasal cavity.

OBJECTIVETo evaluate the effect of endoscopic surgery for maxillary sinus inverted papilloma.

METHODSFrom 2000 to 2011, 50 patients with maxillary sinus inverted papilloma were treated with intranasal endoscopic surgery or combined approach. Among them, 39 cases were primary and 11 cases were recurrent, which included 17 patients with Krouse stage IIand 33 cases with Krouse stage III. Different surgical approaches were selected according to the range and positions of the lesions. One case with severe atypical hyperplasia received postoperative radiotherapy.

RESULTSAll cases were followed up for 3-14 years, 7 cases recurred. All occurrence within 2 years after operation. Malignant change and death was found in 1 case. After operation, epiphora occurred in 2 cases, maxillary sinus labiogingival groove fistula occurred in 2 cases, facial numbness occurred in 4 cases and incision hemorrhage occurred in 1 case. All the complications were cured after appropriate treatment.

CONCLUSIONSNaso-endoscopic surgery or combined approach is a safe, effective and microinvasive treatment for patients with maxillary sinus inverted papilloma. Accurate selection of suitable approach according to the range and positions of the lesions and correct management of the base of the tumor are critical to the success of the operation.

The clinical data of two adolescents with unilateral nasal cavity neoplasm were analyzed. Both were male, one was 14-year-old and the other was 17. Both were complained of unilateral nasal obstruction and nasal discharge; The course of disease of the former was one month ,and that of the latter was three month; both were found neoformation in unilateral nasal cavity in medical examination. Occupying lesion in unilateral nasal cavity and sinus were demonstrated in CT scan of two cases. Endoscopy surgery were operated in both cases, incisal opening in labiogingival groove was added in the latter. Pathology of the former was capillary hemangioma and the latter was rhabdomyosarcoma. No findings indicating recurrence has been observed in two cases under 6 months follow-up. Recognition at nasal cavity and paranasal sinus neoplasm in adolescent is essential so that proper management can be initiated.

Sinonasal cancers account for less than 1% of all malignancies and comprise 3% of all head and neck malignancies. The most common malignant neoplasm in the sinuses and nose is squamous cell carcinoma, which accounts for 70% of these neoplasms. Most of these arise in the maxillary antrum, and only 10% to 30% occur in the nasal cavity or ethmoid sinus. It is well known the surgery is primary treatment for sinonasal malignancies. Adjunctive irradiation and/or chemoradiatioin has resulted in improved locoregional control and increased survival rates. The goal of surgical resection is to remove the cancer en bloc, with clear margin devoid of neoplastic cells. For maxillary sinus neoplasms, maxillectomy is a standard surgical procedure. Neoplasms involving the ethmoid, frontal, or sphenoid sinuses may require a craniofacial approach because of frequent invasion into the skull base. The proximity of the nasal cavity and paranasal sinuses to the adjacent structures including the orbit, dura, brain, cranial nerves, and carotid arteries mandates careful radiologic and neurologic evaluations throughout the course of the disease. Surgical advances now permit complex tumor removal and reconstruction surrounding these structures resulting in functional and cosmetic improvements when compared to earlier techniques.
