Traditionally, surgical access to the midface structures for the removal of benign or malignant tumors has been through paranasal sinuses, external facial incisions, or hard palate. However, large or malignant lesions of the nose, paranasal sinuses and nasopharynx have a particularly difficult problem of these surgical approach. The midfacial degloving approach combined with/without medial maxillectomy provide an alternative method that requires no facial incisions and minimal functional impairment. Exposure and surgical facility may be equal or superior to that of traditional procedures in selected cases. Combining this method with bi-frontal, brow, transtemporal, and transpalatal approach is also possible for extensive lesions. We did midfacial degloving in 13 patients who were seen with benign or malignant lesions involving the midface structures from Jan. 1991 to Dec. 1994. Thus we analysed the clinical data including the advantage and complications of this method retrospectively.

Glomanigiopericytoma is a rare vascular neoplasm with a perivascular myoid phenotype. It is rarely found in the neck but most commonly in the nose and paranasal sinuses. We experienced a case of 72-year-old man who presented a 5-year history of a right neck mass. The pathologic diagnosis was glomangiopericytoma. We removed the mass transcervically and the patient showed no postoperative problem. We report this case with a review of literature.

BACKGROUND AND OBJECTIVES: The main treatment modality of sinonasal benign tumor is surgical resection, and the endoscopic intranasal approach has been commonly performed since the 1990s. The objective of this study was to evaluate the recurrence rates of different sinonasal benign tumors and to analyze the diverse approaches used in their surgical treatment. SUBJECTS AND METHOD: In 270 patients who were histopathologically diagnosed with sinonasal benign tumor during a period of 20 years, histopathologic type, treatment approach, interval between first treatment and recurrence, and recurrence rate according to treatment approach were analyzed. RESULTS: Recurrence rate was higher with the intranasal approach than with the extranasal approach in inverted papilloma and angiofibroma, but the differences were not statistically significant. The proportion of the intranasal approach during the latter 10 years was higher than that during the former 10 years. There was no significant differences between the recurrence rate during the former 10 years and that during the latter 10 years for both intranasal and extranasal approaches. CONCLUSION: Based on tumor location and stage and skill of the surgeon, the intranasal approach can replace the extranasal approach with no major changes in treatment outcome.

While polyposis in the nose and paranasal sinuses continues to be a major clinical problem, the pathogenesis of nasal polyps remains controversial. Many etiologic theories, including those pointing to allergy, have been suggested. Most of the recent studies on nasal polyps focus on two key areas: the molecular and cellular network of the inflammatory process and the mechanisms behind polyp growth. Inflammatory changes in nasal mucosa can increase the effector capabilities of structural cell-derived cytokines, and represent a major amplification pathway of the inflammatory response in nasal polyps. The resultant edema can lead to the growth of nasal polyps. The role of allergy in the pathogenesis of nasal polyps remains unclear, but allergy may be one mechanism driving the chain of events leading to inflammation.

Hamartoma is a non-malignant malformation or developmental anomaly of tissue development that may occur anywhere in the body but is rarely reported in the nasal cavity, paranasal sinuses, or nasopharynx. Chondro-osseous respiratory epithelial adenomatoid hamartoma (CO-REAH) of the nasal cavity is exceedingly rare, and can be confused both grossly and microscopically with more serious sinonasal tumors. We present the case of a 58-year-old man with a nasal cavity mass, which was removed by an endonasal approach. Radiographic and histological studies permitted a diagnosis of CO-REAH in this case.
