Nasal inverted papilloma (NIP) is one primary benign lesion that occurs in the nasal cavity and paranasal sinuses. In this paper, several clinical classifications of NIP were summarized. The most important classification, which was developed by Krouse in 2000, and endoscopic technique was applied to treat NIP in different Surgical methods.

Dear Editor, Papillomas are primary benign epithelial neoplasms producing finger–like projections that typically cover fibrous stalks.1 The term Inverted Papilloma (IP) describes the endophytic projection of epithelium into the stroma. Also known as Schneiderian papillomas, IPs predominantly affect males in the 6th decade.2 They usually arise from the lateral nasal wall and seldom involve the frontal or sphenoid sinuses.2 The frequency of IP on the nasal septum is even less.3 We report a case of IP of the nasal septum and the role of endoscopic resection of the IP without any sign of recurrence.

Objective:To investigate the effectiveness of nasal endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum in resecting recurrent nasal inverted papilloma. Methods:Patients with recurrent nasal inverted papilloma who underwent reoperation in our hospital during the past 2 years were included . The nasal septum may hinder full access to and effective treatment of the lesions at the anterior and medial wall of the maxillary sinus by endoscope, aspirator and surgical instrument in the narrow aperture of the prelacrimal recess, although these lesions could be observed by 70° nasal endoscope. Results:The nasal septum is temporarily opened on the basis of the prelacrimal recess approach, and the nasal endoscope and instrument was introduced through trans-septal window, so as to provide a better view of the operative field and the angular range of the instrument's movement. Conclusion:The recurrent nasal inverted papilloma could be successfully managed by re-endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum, and no recurrence was observed during the 2-year follow-up. This surgical approach is recommended for the inverted papilla which originates from the anterior medial wall of the maxillary sinus, as the tumor can be removed completely using this surgical approach.

OBJECTIVE: Observed the using of coblation during the maxillary sinus operation, to investigate the superiority of its clinical application. METHOD: Selecting 46 patients with the maxillary sinus lesions of sinusitis, nasal polyps and nasal inverted papilloma as research objects, the control group used high speed cutting drill, the research group used coblation separately for functional endoscopic sinus surgery. Six months postoperative follow-up, observeing the subjective symptoms and objective examination. RESULT: Subjective symptoms and objective examination scores of two groups of patients improved significantly. Compared with the control group, the operation time, bleeding volume and postoperative examination time are reduced in the study group of patients. Endoscopic examinations of the study group are better than the control group. CONCLUSION Using coblation for the maxillary sinus operation, treatment are more thorough, more minimally invasive, shorten operation time, reduce bleeding and recheck time after surgery, is worthy of clinical use.

OBJECTIVE: To evaluate the effect and application value of endoscopic resection in sinonasal inverted papillomas. METHOD: In a retrospective study, clinical data of 40 patients underwent transnasal endoscopic approach in Chinese PLA General Hospital from July 1999 to April 2005 were analyzed. Tumor stage according to Krouse was T1: 4, T2: 23, T3: 12, T4: 1, respectively. RESULT: All lesions were removed completely and 5 patients received post-operative radiation therapy. There were no serious complications occurred. The follow-up period ranged from 24 to 93 months (mean, 45.1 months). Recurrence rate was 15% (6/40) and the rate of malignant transformation and mortality were 7.5 % (3/40), respectively. Average time to recurrence was 37.3 months. CONCLUSION Endoscopic surgery offers a safe and effective treatment for sinonasal inverted papillomas with a minimally invasion. Thorough removal of the tumor and regular follow-up are the key points for success.

OBJECTIVETo investigate the clinical manifestation, biological behavior, diagnosis and treatment of the urothelial inverted papilloma.

METHODSSixty-two cases of urothelial inverted papilloma were analyzed retrospectively from January 1990 to August 2008. Of the 62 patients, 51 were men and 11 were women. The average age at presentation was 56.4 years old. Fifty-six cases were solitary tumors and 6 were multiple. The most common compliant was macroscopic hematuria. The tumor located at the ureter in 5 cases. Of these cases, 4 were treated by local excision, 1 by nephroureterectomy. One case of multiple ureteral inverted papilloma with coexistent bladder inverted papilloma was treated by total cystectomy. The tumor located at the bladder in 52 cases, with 44 treated by transurethral resection of bladder tumor, 6 by partial cystectomy, 2 by total cystectomy. Four cases had the tumor located at the urethra, with 1 treated by transurethral resection of tumor, 3 by tumorectomy.

RESULTSThe postoperative pathological diagnosis of all the 62 cases was inverted papilloma, synchronous urothelial carcinoma in 7. Follow-up data were available in 49 cases. Two cases had a recurrence at 7 months and 79 months, respectively. Three case of subsequent transitional cell carcinoma developed 18 months, 2 years and 6 years later, respectively.

CONCLUSIONSInverted urothelial papilloma is a kind of benign tumor. It should be differentiated from malignant urothelial tumors. Surgical operation is the main treatment choice. Cystoscopic surveillance and followup are necessary after the operation regularly.

BACKGROUNDThe inferior turbinate (IT) and nasolacrimal duct (NLD) are often sacrificed while managing the diffuse lesion of maxillary sinus (MS). We report a new approach to MS without ablation of NLD and IT.

METHODSThis retrospective study enrolled 19 hospitalized patients (aged from 42 to 68 years) who underwent endoscopic sinus surgery between 2003 and 2008. Twelve patients had inverted papilloma (IP), two had nasal polyps, two had Kubo's postoperative cyst of MS, one had recurrent bone cyst of maxilla, one had dentigerous cyst and one had bleeding of internal maxillary artery secondary to Caldwell-Luc operation respectively. Two IP patients were excluded from this group since the follow-up time was less than 12 months. The NLD was dissected after removing the anterior bony portion of nasal lateral wall. The prelacrimal recess approach (PLRA) to MS was established when IT-NLD flap was raised medially. The flap was repositioned when MS lesion was removed.

RESULTSAll the 17 patients had unilateral lesions. Ten MS IP patients were at the T3 Krouse stage. The follow-up ranged from 7 to 60 months. No recurrence was seen in 16 patients. Only one IP patient had a local recurrence in MS. All of them had no any complications.

CONCLUSIONThe diffuse or severe diseases of MS may be the potential indications for PLRA.

OBJECTIVE: To summary the clinical characteristics and outcomes of nasal inverted papilloma treated by intranasal endoscopic approach. METHOD: Fourty-six patients with nasal inverted papilloma were treated with endoscopic surgery from 1995 to 2005. There were 34 males and 12 females, age ranged from 18 to 76 years old. The period of follow-up was 12-72 months. RESULT: Only 5 cases recurred within 24 months after the surgery. The other cases had no recurrence during the follow-up period. CONCLUSION The endoscopic endonasal approach is an effective treatment for an inverted papilloma in selected cases. A combination of Caldwell Luc procedure and transnasal endoscopic sinus surgery may be needed for those patients with inverted papilloma in stage III.
