Two Cases of the Inverted Papilloma in the Maxillary Sinus Treated by Modified Transnasal Endoscopic Medial Maxillectomy / 대한이비인후과학회지

ABSTRACT

Although inverted papilloma (IP) of the nose and paranasal sinus is a benign neoplasm, it is associated with frequent recurrence and malignant transformation. Various surgical techniques have been employed for resection of this tumor. Transnasal endoscopic medial maxillectomy (TEMM) is an effective surgical management of IP originating from the maxillary sinus. It usually removes the inferior turbinate, lateral wall of the nasal cavity, and nasolacrimal duct, and may cause adverse effects such as atrophic rhinitis, empty nose syndrome, impairment of nasal physiological function, and epiphora. Recently, however, a modified TEMM, which preserves the inferior turbinate, lateral wall of the nasal cavity, and nasolacrimal duct has been introduced. We present two cases of IP successfully treated by the modified TEMM.
