The surgical modalities for treatment of chronic maxillary sinusitis have changed in recent years. The radical Caldwell-Luc operation has been replaced by the more conservative endoscopic sinus surgery(ESS). Good clinical results for the ESS technique have been reported(Wigand, 1978 ; Stammberger, 1991 ; Kennedy, 1992), but only a few papers give detailed data on the symptoms(Kamel, 1989 ; Levin, 1990 ; Lund, 1991). From April 1992 to January 1996, a total of 118 patients(primary ESS 62 patients and ESS after previous nasal surgery 56 patients) who underwent ESS at the department of otolaryngology, Ewha womans university Hospital, were evaluated.

Preoperative nasal symptoms, except for nasal discharge were higher in revision cases. The previous most common nasal surgery was polypectomy accounting for 25(44.6%) of the 56 revision cases. All had preoperative CT scans of the ostiomeatal unit area(OMU CT) and severity of inflammatory disease had been graded by CT. In revision cases, 30(53.6%)cases had complete opacification of one or more major sinuses. But in primary ESS cases, 19(30.6%) had findings limited to the osteomeatal complex. Overall, 43(76.8%) patients benefited from ESS in revieion cases, and 58(93.5%) in primary ESS cases. Synechia was the most common complication in revision and primary FESS cases. The difference of outcomes between primary ESS and ESS after previous nasal surgery is explained by the difference of preoperative state of the sinus mucosa.

The author's review of 118 patients showed that there was significant difference in the postoperartive success rate between the primary ESS and ESS after previous nasal surgery.

Chronic maxillary sinusitis is one of the most common disorder in pediatric otolaryngology and it is remained also the major problem restrict to management. Management of the children with chronic maxillary sinusitis is a through search for underlying etiologic anatomical, systemical and local factor. As one of etiologic factors, hypertrophied tonsils and adenoid cause obstruction of narrow ansopharynx and stagenation and infection of paranasal sinus. But chronic maxillary sinusitis is remained uncontrolled disease in spite of tonsillectomy and adenoidectomy, maxillary antrum prncture and irrigation, and antibiotic therapy.

This follow up research was performed in 104 cases that received tonsillectomy and adenoedectomy at department of otolaryngology, Ewha University Hospital during last 5 years(from 1986 January to 1990 December), they showed chronic maxillary sinusitis by preoperative PNS X-ray.

The result was that improvement of chronic maxillary sinusitis was noted in 57% at survey study and in 63% at PNS x-ray study after tonsillectomy and adenoidectomy.

was effective in treating chronic maxillary sinusitis in children.

Benign Symmetric Lipomatosis is a lesion characterized by symmetric and diffuse growth of adipose tissue.

It is commonly found in the posterior neck or upper trunk, but oral involvement is extremely rare.

Authors experienced a case of Benign Symmetrical Lipomatosis of tongue. The tumors was completely removed out under the general anesthesia.

Histopathologic examination verified Benign Symmetric Lipomatosis of tongue. So, authors report this case with brief review of literatures.
