The new classification system, based on the origin of IP, is a simple tool for grading IP. It can be used to define cases suitable for conservative excision or radical medial maxillectomy. Both could be performed transnasally and endoscopically.
Purpose of reviewTo highlight how surgery of inverted papilloma has developed during the past year. Moreover, to give our own opinion on the state of research regarding inverted papilloma surgical management.
Recent findingsRecent studies covering surgical treatment of inverted papilloma concentrated on the optimum surgical management aiming at complete resection, least morbidity and best outcome, with special interest regarding the maxillary and frontal sinuses. In maxillary sinus inverted papilloma, to avoid empty nose and/or epiphora, recent articles exerted all attempts to preserve the integrity of both the inferior turbinate and nasolacrimal duct, yet offer best exposure of all maxillary sinus walls specially the anterior and inferior ones. These included the new modifications of the prelacrimal and Denker approaches and lateral nasal wall transposition. In frontal sinus inverted papilloma, to avoid an external approach and insure postoperative patency of frontal sinus ostium, the periorbital suspension was introduced and orbital transposition approach was comprehensively utilized especially in far lateral located lesions and/or in supraorbital recess involvement. Associated malignancy is an important issue to identify as management plans significantly differ. Recurrence occurs early within the first 2 years but long-term follow-up is mandatory.

ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ـ Aim and objectives: Evaluation of the efficacy of intracapsular microdebrider tonsillectomy in comparison to extracapsular conventional surgical tonsillectomy regarding timing, postoperative pain, amount of blood loss, tonsillar fossa healing and complications. Methods: Controlled, prospective, and comparative study was done on 25 patients (14 female and 11 male) aged from 4-12 years old. Those patients received intracapsular microdebrider tonsillectomy on the left side and conventional extracapsular surgical tonsillectomy on the right side. Results: Intracapsular microdebrider tonsillectomy had a significant less pain post tonsillectomy, there was a great
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
