The surgical approach for the removal of inverted papilloma (IP) involving the frontal sinus (FS) depends on the site of tumor origin. This study was designed to determine the appropriate surgical approach according to the site of origin in the FS. Subjects and Method:Eleven patients with IPs originating from the FS, who had surgery at the department of ORL-HNS, Pusan National University Hospital from 1998 to 2007, were retrospectively reviewed for the site of tumor origin, surgical approach, recurrence, mode of reoperation, and complications. The mean age was 53.8 years with a male-to-female ratio of 7:4. The average follow-up duration was 35.7 months. Results:The sites of tumor origin were the whole wall (2/11), medial wall (3/11), intersinus septal cell (2/11), lateral wall (1/11), posterior wall (1/11), anterior wall (1/11) and diffuse whole wall with invasion into the opposite sinus (1/11). In the two cases with whole wall involvement, one was treated by an osteoplastic frontal sinus surgery (OPF) and the other by a modified endoscopic Lothrop operation (MEL). The case with diffuse anterior wall origin was treated by OPF. For the two cases with the intersinus septal cell origin, one was reoperated using MEL after recurrence and the other was initially treated with MEL. A recurrent case with the lateral wall origin was reoperated by MEL. IPs originating from the posterior or medial wall were successfully managed by endoscopic surgery /c or /s trephination. Conclusion: IPs originating from the FS were successfully managed by the integrated endoscopic-assisted approach to the FS. Especially, MEL was a safe and effective alternative treatment to OPF for IPs originating from the FS. (Korean J Otorhinolaryngol-Head Neck Surg 2008;51:800-4)

Background and Objectives The objective of this study is to determine the appropriate surgical approach for the resection of inverted papilloma (IP) involving the maxillary sinus (MS)according to the site of tumor origin in the MS. Subjects and MethodZZTwenty-six patients who underwent surgery from January 2002 to April 2008 for IP originating from the MS were reviewed retrospectively in regard to the type of integrated surgical approach, site of tumor origin in the MS and the follow-up clinical results. ResultsZZTen cases (38.4%) originated from medial wall of the MS; of these, four EES (endonasal endoscopic surgery), two EMM (endoscopic medial maxillectomy), two EES+CP (canine puncture), and two EES+CLA (Caldwell-Luc’s approach) were performed. EES+CP procedure were performed in all three cases (11.5%) of the anterior wall origin. One case (3.8%) that originated from the posterolateral wall was removed by EES+CLA. Four cases (15.3%) originated from the medial-posterolateral wall. Two EES, and one each of EMM and EES+CLA were performed. Three cases (11.5%) originated from the superior-posterolateral wall, of which two cases were removed by EES and the other by EES+CLO (Caldwell-Luc’s operation). Two cases of inferior-anterior wall and inferior-posterolateral wall were removed by EES+CLO and EES+CLA, respectively. EES+CLO were performed for three cases of the whole wall origin (11.5%). Two recurrent cases were found in each of EES and EES+CLO. ConclusionZZIP originated from the MS were successfully managed by EES alone or EES combined with other approaches such as CP, CLA, CLO and EMM. These integrated approaches need to be applied in a gradual manner from less severe to more aggressive cases. Korean J Otorhinolaryngol-Head Neck Surg 2010;53:148-52

Background and Objectives:This study was designed to isolate bacteria and fungi from healthy ear canal in Koreans and compare with known pathogens. Subjects and Method:Specimens were collected from the external ear swab and cerumen of 45 healthy volunteers from February 2003 to May 2003. Results:Forty-five subjects were cultured. In 8 subjects, we failed to of which 84.7% were gram positive bacteria. Twenty-six cerumen specimens yielded 43 microorganisms and 76.7% of them were gram positive. Staphylococci was 76.4% of canal bacteria and 74.4% of cerumen bacteria. In both canal and cerumen, the most comonly isolated microorganism was Staphylococcus capitis. Coryneform bacteria were 6.9% of bacteria in canal and were not isolated from cerumen. Two Aspergillus species and one Penicillium Conclusion:Coagulase-negative staphylococcus (CNS) were found to be the predominant microorganism and, in particular, Staphylococcus capitis was the most commonly isolated microorganism from the normal external auditory canal in Koreans.

Background and Objectives:The reports of normative measurements for inner ear structure using computer-based programs are rare. The purpose of this study was to measure the normative data of the Korean inner ear structures and establish the basic data for diagnosis of congenital inner ear anomaly. Subjects and Method:Temporal bone CT of 38 patients (16 men and 22 women) without apparent disease of middle and inner ear, fractures or major disorder such as seizure or tumor were retrospec-tively reviewed. Fifteen dimensions on axial views and 9 dimensions on coronal views were measured in PACS using π-view program. The slice thickness of CT was 0.6 mm. Results:From the axial view, the canal diameter of SC was 1.09± 0.15 mm, the bony island width was 5.70± 0.50 mm, the bony island width of LSC was 3.99± 0.58 m, the cochlear upper turn width & height were each 5.63± 1.07 and 3.03± 0.65 mm. The vestibular aqueduct were observed 95.3%. From the coronal view, the cochlear height was 5.14± 0.36 m. The length of IAC was significantly longer in male than female (p<0.05)site of IAC was significantly wider in the left than the right (p<0.05). The upper turn of cochlea in good bone conduction (≤10 B) had larger width and smaller height than those in poor bone conduction (>10 dB). Conclusion:We established the Korean normative measurements of the inner ear structures, which can be used for further diagnosis of the inner ear anomaly. 0.6 m slice로 촬영된 TBCT에서 38예 43귀를 파이뷰 프로그램을 이용하여 축상 스캔에서 15가지, 관상 스캔에서 9가지의 내이 구조물을 계측하여 다음과 같이 요약한다. 1) 파이뷰 프로그램을 이용한 계측이 필름상에서 캘리퍼를 이용하여 계측하는 것보다 더욱 정밀하게 측정할 수 있었다. 2) 내이도의 관상 스캔에서 남성이 여성보다 유의하게 그 길이가 길었고, 내이도 입구부 직경이 좌측이 우측보다 유의하게 넓었다. 3) 와우 상부회전이 포함된 와우골관의 폭은 골도 청력이 정상인 예에서, 그 높이는 골도 청력이 저하된 예에서 통계적으로 유의하게 큰 계측치를 보였다. 이상에서 파이뷰 프로그램을 이용한 측두골 계측이 내이 기형의 진단에 유용한 기초적 자료를 제공할 것으로 사료되며, 추후 많은 예에서 깊은 연구가 필요하리라 생각된다.
