Findings in the nasal cavity were similar to those after ESS Figure 5and the patient did not complain of either an empty nose or dryness in the nose.

As familiarity and expertise with endoscopic techniques increase, these approaches are being used more frequently in the extirpation of sinonasal tumors. Iatrogenic factors involve inadvertent stripping of sinus mucosa, damage to the cilia bearing endoscipic with the microdebrider or other instruments, exposure of bone, circumferential damage to the sinus ostium, improper widening of sinus ostium permitting recirculation of mucous, poor mucociliary clearance, among others.

We feel that merely taking down the medial wall of the maxillary antrum does not serve the purpose in patients with irreversible mucosal injury and necessitates a more radical procedure like a type IIb MEMM.

Though the ciliary mechanism is lost, the goblet cells continue to secret mucus, which results in stasis, an additional factor. Sinonasal inverted papillomas IPs are one of most commonly found benign tumors in the maxilllectomy sinuses [ 1 ]. We have attempted to highlight this point through this article.

Our study is an attempt to define this subset of patients and a protocol for the treatment of these patients see Fig. Before surgery, IP must be diagnosed based on distinctive clinical and imaging findings of the nasal cavity. MRI T1 Gd-DTPA shows secondary maxillary sinusitis and a serpentine cerebriform filamentous structure, but there is no mass to otherwise indicate a possible origin.

Endlscopic endoscopic techniques entailed an extended maxillary antrostomy with piecemeal resection of tumor of the lateral nasal wall. Tanna, Edwards, and Aghdam. En block resection is desirable, but this is difficult with an endoscope owing to the limited visibility of the operative field.
