Sinonasal papillomas in a private referral otorhinolaryngology centre: Review of 22 years experience. / Papilomas rinosinusales en un centro de referencia otorrinolaringológico privado: revisión de 22 años de experiencia.

OBJECTIVES: To evaluate the clinical presentation, treatment outcome and follow-up of all patients managed with sinonasal papillomas (SP), at a tertiary private otorhinolaryngology centre in Caracas (Venezuela). MATERIAL AND METHODS: We reviewed 94 patients with SP that were treated at our otolaryngology center, from July 1st 1993 to June 31st 2015. The demographic data, clinical features, radiological findings, anatomical origin, disease extension into the adjacent structures, surgical approaches performed, histopathology outcomes, recurrent risk, malignant transformation rate and coadjuvant therapies were assessed. RESULTS: Sixty-five patients (69.1%) were male and 29 (30.9%) female with an average age of 44.5 years (range 9-80 years). All patients underwent endoscopic sinus surgery. The most commont histologic subtypes of SP were inverted papilloma (58 patients; 61.7%), fungiform papilloma (35 patients; 37.2%) and oncocytic papilloma (one patient; 1.1%). SP was associated in 2 patients with undifferentiated squamous cell carcinoma. Twelve patients (12.8%) had disease with extension beyond the sinus without associated malignancy. All these patients received adjuvant treatment with advanced techniques of radiotherapy. The mean duration of the follow-up period was 9 years and 2 months. Eighteen patients (19.1%) had recurrent disease during the entire course of follow-up. CONCLUSIONS: Complete endoscopic surgical removal of SP is the treatment of choice. In less endoscopically accessible tumours, with peripheral extension or incompletely resected, Intensity Modulated Radiotherapy and Volumetric Modulated Arc Therapy may be indicated. Timely post-operative endoscopic follow-up with biopsy of suspected lesions is important for early detection of recurrences and associated malignancy.

Papiloma invertido rinosinusal recurrente bilateral, con extensión intracraneal e intraorbitaria. Reporte de un caso / Recurrent and bilateral inverted sinonasal papilloma with intraorbital and intracranial extension.

El papiloma invertido (PI) es una neoplasia relativamente rara de la cavidad nasal y los senos paranasales. Se la considera un tumor benigno, pero su comportamiento biológico no es tan benigno por su crecimiento local agresivo, tasa alta de recurrencia, y riesgo de transformación maligna con asociación a carcinoma. Por tanto, requiere una extirpación quirúrgica completa y seguimiento postoperatorio a largo plazo. El PI bilateral es infrecuente y lo es aún más cuando se asocia con extensión intraorbitaria e intracraneal simultáneas. Estos comportamientos extremadamente agresivos han sido reportados por separado, especialmente en casos recurrentes. Ha sido excepcional el informe de casos con enfermedad bilateral y compromiso multifocal, sin malignización asociada. En estos casos el tratamiento quirúrgico recomendado es el abordaje endoscópico endonasal combinado con abordajes externos (convencional o minitrepanación endoscópica). La radioterapia de intensidad modulada puede ser de gran utilidad en pacientes con enfermedad resecada de manera incompleta. Se presenta un caso de esta rara enfermedad.

Inverted papilloma (IP) is a relatively rare neoplasm of the nasal cavity and paranasal sinuses. Although it is considered a benign tumor, its biological behavior is not so benign because of local aggressive growth, high recurrence rate, and risk of malignant transformation with associated carcinoma. Therefore, it requires complete surgical removal and long term postoperative follow-up. Bilateral IP is unusual and even more so when associated with simultaneous intra-orbital and intra-cranial extensions. These extremely aggressive behaviors have been separately reported in the literature, especially in recurrent cases. Report of cases with bilateral and multifocal involvement without malignancy has been exceptional. Surgical management in these cases includes an endonasal endoscopic approach combined with external approaches, either conventional or endoscopic minitrepanation. Intensity modulated radiation therapy can be useful in patients with incompletely resected disease. A case of this rare disease is reported.

Endoscopic septoplasty in primary cases using electromechanical instruments: surgical technique, efficacy and results.

INTRODUCTION AND OBJECTIVES: The microdebrider is a surgical tool which has been used successfully in many endoscopic surgical procedures in otolaryngology. In this study, we analysed our experience using this powered instrument in the resection of obstructive nasal septum deviations. SUBJECTS AND METHODS: This was a longitudinal, prospective, descriptive study conducted between January and June 2007 on 141 patients who consulted for chronic nasal obstruction caused by a septal deviation or deformity and underwent powered endoscopic septoplasty (PES). RESULTS: The mean age was 39.9 years (15-63 years); 60.28% were male (n=85) The change in nasal symptom severity decreased after surgery from 6.12 (preoperative) to 2.01 (postoperative). Patients undergoing PES had a significant reduction of nasal symptoms in the pre- and postoperative period, which was statistically significant (P<.05). There were no statistically significant differences between the results at the 2 nd week, 6th week and 5th year after surgery. The 100% of patients were satisfied with the results of surgery and no patient answered "No" to the question added to compare patient satisfaction after surgery. Minor complications in the postoperative period were present in 4.96% of the cases. CONCLUSIONS: Powered endoscopic septoplasty allows accurate, conservative repair of obstructive nasal septum deviations, with fewer complications and better functional results. In our experience, this technique offered significant perioperative advantages with high postoperative patient satisfaction in terms of reducing the severity of nasal symptoms.
