“…12 21 29 The residual respiratory epithelium usually remains intermingled with the metaplastic squamous epithelium, creating numerous SCJs in the three dimensional array of these extensive lesions. [38][39][40][41] In addition to such abrupt junctions, small microcystic spaces regularly remain within the squamous epithelium, as an indication of the progressing squamous metaplasia.…”

Objectives/Hypothesis To explain the processes that lead to the development of tumors in the maxillary and sphenoid sinuses. Study Design A 32‐year review of the world's literature on neoplasms of these two sinuses and a randomized case‐controlled study comparing the normal mucosal architecture of the maxillary to the sphenoid sinus. Methods Analysis of a 32‐year world literature review reporting series of cases of maxillary and sphenoid sinus tumors. Tumors were classified by histological type and separated into subgroups if an individual incidence rate was reported. Histomorphometry of normal maxillary and sphenoid sinus mucosa was performed in 14 randomly selected patients (10 sphenoid and 4 maxillary specimens). Specimens were fixed in 10% formalin, embedded in paraffin, and stained with periodic acid–Schiff (PAS) and hematoxylin. Histomorphometric analysis was performed with a Zeiss Axioscope light microscope (Carl Zeiss Inc., Thornwood, NY) mounted with a Hamamatsu (Hamamatsu Photonics, Tokyo, Japan) color‐chilled 3 charge coupled device digital camera. The images were captured on a 17‐inch Sony (Sony Corp., Tokyo, Japan) multiscan monitor and analyzed with a Samba 4000 Image Analysis Program (Samba Corp., Los Angeles, CA). Five random areas were selected from strips of epithelium removed from each sinus, and goblet and basal cell measurements were made at magnifications ×100 and ×400. Results The literature review revealed that the number and variety of tumors in the maxillary sinus are much greater than those in the sphenoid. The incidence of metastatic lesions to each sinus is approximately equal. No recognized pattern of spread from any particular organ system could be determined. On histomorphometric study there were no statistically significant differences between the sinuses in the concentration of goblet cells, basal cells, or seromucinous glands. Conclusions Factors involved in the pathogenesis of tumors of the maxillary and sphenoid sinuses include differences in nasal physiology, embryology, morphology, and topography. There are no significant histological differences in the epithelium and submucous glands between the two sinuses to explain the dissimilar formation of neoplasms.

Inverted papilloma, although benign, recurs frequently and may become malignant, making definitive initial resection extremely important. We evaluated surgical procedures for recurrence and sites, with special reference to management of the orbital plate of the ethmoid and lacrimal bones, in 24 patients (32 cases) with inverted papilloma of the nasal cavity and paranasal sinuses undergoing surgical resection from 2000. Nine of the 32 showed recurrence, all around the ethmoid orbital plate. Up to 2002, recurrence was noted in 7 of 17 cases (41%), so we changed surgical selection criteria. Since 2003, we have conducted partial and combined excision of the orbital plate of the ethmoid and lacrimal bones (extended operation of the extranasal ethmoid and frontal sinuses) in cases in which tumors adhered to the orbital plate, noting recurrences in only 2 of 15 cases (13%). A number of reports advocate endoscopic sinus surgery to minimize invasiveness for inverted papilloma, but partial and combined excision of the orbital plate is indispensable, in progressive inverted papilloma cases to reduce recurrent.
