ranged from 2-3 years. The surgical intervention procedureswere Submucous diathermy (25 patients), Turbinoplasty (85patients), and Turbinoplasty with posterior turbinectomy (105patients). The patients were followed up regularly every weekfor three weeks, then every three months for at least two years.Doctor assessment scale and patients’ assessment score werefilled in during every visit until the end of the follow-up periodand any remarks were recorded and dealt with accordingly.RESULTS: Nasal pack for one day was a standard protocolfollowing surgery. Patients in group A (Submucous diathermy)were the last patients to record a better quality of breathingfollowing surgery; 18 patients (72%) recording a better breath-ing 8 days after surgery compared to 70 patients (82.4%) ingroup B (Turbinoplasty) and 96 patients (91.4%) in group C(Turbinoplasty with Posterior Turbinectomy). Tendency forpostoperative nasal bleeding was not significantly higher inany of the studied group (p-value � 0.1). The overall patientsatisfaction was significantly higher in group C than group Bwhich was also significantly higher than group A (p-value �0.05). Doctor’s satisfaction came in accordance with patients’satisfaction.CONCLUSION: Posterior turbinectomy with turbinoplastygives a better surgical outcome and better patient satisfaction incases of inferior turbinate hypertrophy than submucous dia-thermy or turbinoplasty alone.

OBJECTIVE: To determine the prevalence of environmentalallergens in a British cereal farming population population.METHOD: Study Design: Retrospective chart analysis. Whenconducted: Over a staggered 3 year period, comprising a2-year period (January 2003 - December 2005) and 1-yearperiod (September 2008 - September 2009). Subjects Studied:The results of 1475 consecutive patients who underwent skinprick allergy testing over a 2-year period and of 640 consec-utive patients over a separate 1-year period were analyzed andcompared. Setting: General population within a mixed cerealfarming area attending a rhinology and allergy clinic in adistrict general hospital, UK. Outcome Measures: Positiveskin-prick allergy test(s).RESULTS: Allergy to house dust mite was found to be mostcommon (n�526, 25%), followed by grass pollen (n�519,24%) and cereals (n�429, 20%). Oilseed rape hypersensitivitywas relatively uncommon, comprising only 2% of the popu-lation tested (n�28).CONCLUSION: Despite living in an area rich in cereal crops,our population experiences allergens similar to other popula-tions. Interestingly, oilseed rape does not cause significant

allergy, despite being commonly cited as a culprit, even inareas of high production.

Recurrence Rate of Sinonasal Papilloma by Surgical

Technique

Paul Russell, MD (presenter)

OBJECTIVE: Inverted papilloma is a relatively rare benigntumor that arises within the nasal cavity. These tumors are ofparticular importance because they tend to be locally aggres-sive and can occasionally be associated with malignancy.Treatment options can be generally classified into endoscopicresection and open resection that may include lateral rhino-tomy and maxillectomy. Advantages of endoscopic resectioninclude employing a minimally invasive approach withoutexternal incisions. The concern with the endoscopic approachis that complete removal of the tumor may be difficult leadingto an increase in recurrence rate. Our experience is that com-plete removal can in fact be accomplished endoscopically andmay actually be enhanced due to improved visualization frommagnification with the endoscope. To that end, we propose acomparison of the recurrence rates of the endoscopic approachversus open approach over a ten-year period at VanderbiltMedical Center.METHOD: A retrospective analysis from the dates of June 30,2000, until July 1, 2009, was undertaken for patients with thediagnosis of sinonasal papilloma by two providers in the divi-sion of rhinology at a single major academic institution. Onehundred twenty patients were analyzed and were stratifiedbased on surgical method employed, either open resection orendoscopic resection. Demographic data was collected andoutcomes were measured including size of tumor, location,pathological subtypes, associated polyposis, complications,years of follow up, and recurrence rates.RESULTS: Endoscopic approach yielded a recurrence rate ofless than five percent when compared to open approach. Thisfinding was independent of size or location of tumor withfewer complications.CONCLUSION: Endoscopic resection yields substantially re-duced recurrence rates and fewer complications when com-pared to open resection. Endoscopic resection should beviewed as the procedure of choice for the management ofsinonasal papilloma.
