The endoscopic approach was performed through a small bone window by the midline of the glabella, with the restoration of the bone support at the end of the surgery using a titanium mesh.

Papilloma sinus mri hypotheses have been taken into consideration: traumatic or infectious triggers, calcium metabolism disorders, or embryonic malformations 5. Frontal sinus osteoma grading system 6 Grade I. The base of attachment is posterior-inferior along the frontal recess. The tumor is medial to a virtual sagittal plane through the lamina papyracea.

Grade II. Grade III. Grade IV. Tumor fills the entire frontal sinus the current case. Osteomas are white, hard, well circumscribed, round or oval, sesile rarely pediculatedbosselated tumors. Histologically, osteoma is composed of lamellar, mature bone with haversian-like systems, surrounded papilloma sinus mri fibrous, paucicellular stroma 7. The diagnosis of osteoma is established by clinical and paraclinical exams.

The patients may complain of persistent frontal pain unresponsive to analgesic or antiinflammatory medication, hemifacial pain, rhinoreea and nasal obstruction.

The postoperative complications which may occur are: subcutaneous emphysema, persistent suppurative sinusitis, fistulization, frontal osteomyelitis, supraorbitar nerve branches damage, papilloma sinus mri neuralgia, ecchymosis, palpebral edema, dyplopia, epiphora, frontal recess stenosis, recurrence detoxifiere cu hrisca si iaurt frontal sinusitis, and tumoral recurrence.

The current case had a classic, slow onset and progression, affecting a middle aged female patient.

Inverted Papilloma

The symtoms have occured gradually: progressive headache  started 12 months before the admission to the hospital.

The presumptive diagnosis was established after clinical and paraclinical examinations transnasal endoscopy, native computed tomography of the papilloma sinus mri and paranasal sinuses. The definitive diagnosis was established by the histological examination of the tumor.

Considering the size of the tumor 4th grade, taking into consideration the classification of osteomas mentioned abovethe decision regarding the therapeutic approach was taken and the combined approach surgery was performed: external and endoscopic, which papilloma sinus mri the ablation of the tumor, as well as proper postoperative drainage of frontal sinus.
