Lymphatic malformation is a congenital abnormality of the lymphatic system, which manifests frequently at birth or before 2 years of age. Lymphatic malformations are classified as macrocystic or microcystic. Microcystic lesions typically occur above the level of mylohyoid muscle and need conservative treatment rather than surgical resection because of the high rate of incomplete excision and recurrence. We report our experience with two cases of radiofrequency ablation of lymphatic malformation in the oral cavity recently seen in our practice.

BACKGROUND AND OBJECTIVES: This study investigated the surgical methods and their results according to the subtypes of zygomatic fractures. SUBJECTS AND METHOD: Medical records of 99 zygomatic fractures treated between March 1997 and December 2006 were reviewed regarding fracture type, surgical method and time of operation from the initial trauma. RESULTS: Overall, operations were performed in 70 out of 99 cases. For zygomatic arch fractures, facial asymmetry and trismus in all 14 of 20 cases after surgery by Gillies incision were improved, and one revision procedure was performed. For tetrapod and multifragment fractures, one revision procedure was performed because of displacement of repaired bone fragment following surgery in 60 cases. Considering location and replacement of fractures, surgery was performed through one of incisions below: Gillies, lateral canthal, gingivobuccal, and subcilliary incision. All preoperative symptoms were improved. CONCLUSION: For zygomatic arch fractures, Gillies approach would be an optimal method, while for displaced tetrapod and multifragment fractures, two or more point fixation points would achieve satisfactory results.

The most possible complication of transnasal reconstruction of medial orbital wall fracture is infection of the dependent sinuses. As a result, endoscopic reduction in a medial blowout fracture with sinusitis and nasal polyp has been avoided. The silastic sheet and Merocel packing, which are placed in the ethmoid sinus, may cause or worsen sinusitis since they could cover up the natural ostia in the vicinity of sinuses. The spread of infection into the orbital wall and the difficulty of recognizing between herniated orbital tissues, infection and nasal polyp makes it difficult to perform endoscopic reduction when there are concomitant sinusitis and nasal polyp. The author reports three recently encountered cases of endoscopic reduction of medial blowout fracture with sinusitis and nasal polyp.

BACKGROUND AND OBJECTIVES: Since chronic E-tube dysfunction is believed to play an important role in the development of otitis media, it is necessary to evaluate the function of the E-tube clinically. Recently, the endoscopic techniques have been used more frequently to directly inspect the E-tube orifice. In this study, I evaluated the morphologic and dynamic motion of the E-tube orifice with 4 mm 30 degrees videoendoscope and compared with the other existing tests of the E-tube function. SUBJECTS AND METHOD: 101 E-tubes with chronic otitis media were selected. I performed the transnasal 4 mm 30 degrees videoendoscopic examination of the pharyngeal E-tube orifice when patients were swallowing, and classified morphologic and dynamic findings of the E-tube orifice into three categories as follows: Type A, the E-tube is opened widely on swallowing with normal mucosa (normal); Type B, the E-tube is not opened with normal mucosa (functional blockage) and Type C, the E-tube is not opened with pathologic mucosa (mechanical blockage). Throughout the study, the control group was 60 E-tubes that were free of ear pathologies. RESULTS: There were more type As in the control group than in the otitis media group according to videoendoscopic findings of the E-tube orifice. The videoendoscopic analysis of the E-tube orifice had a close correlations with the results of inflation deflation test and with the classification of otitis media, but had no significant relationship with the degree of mastoid pneumatization. CONCLUSION: The morphologic and dynamic examination of the E-tube orifice with videoendoscopic techniques may be an important and useful method to examine the tubal function as well as its dysfunction.
