Figure 5. Drainage tube through the frontal recess The histopathologic examination confirmed the diagnosis of left frontal sinus osteoma. The postoperative evolution was favorable. The patient received i. Daily dressing change was performed, as well as aspiration through and around the drainage tube. The postoperative Papilloma nose and paranasal sinuses reevaluation was performed after 14 days Figure 6at one month, at three months, and at six months. Figure 6. ENT reevaluation at 14 days after surgery Discussion Osteoma is the most common tumor papilloma nose and paranasal sinuses paranasal sinuses, often with a slow and silent evolution.

The most frequently involved site is frontal sinus, followed by ethmoid and maxilar sinuses.

[Nasal sinus papillomas].

The sphenoid sinus is rarely involved 1,2. In general, the dimension of osteomas may vary between 2 and 30 mm. Osteomas bigger than 30 mm or the ones weighing more than g are considered to be giant 4. The etiology of osteomas is still unknown.

Several 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 operazione papilloma intraduttale plane through the lamina papyracea. Grade II. Grade III. Grade IV. Tumor fills the entire frontal sinus the current case.

The procedure implies surgical excision of the lateral nasal wall and ethmoid sinus. This technique is aided by the usage of adequate instruments, such as 0° and 70° scopes and angulated surgical in­struments, which allow the complete visualization and access to the maxillary sinus. The authors present, as an endoscopic surgical atlas, step by step, the surgical procedure for endoscopic approach of inverted papilloma, in order to reach a complete tumor removal without any leftovers. Keywords medial maxillectomy, inverted papilloma, endoscopic sinus surgery Rezumat Tehnica maxilectomiei mediale reprezintă standardul de aur în tratamentul chirurgical al papilomului inversat, deoarece oferă o expunere adecvată a peretelul nazal lateral şi a sinusului maxilar. Intervenţia include excizia chirurgicală a peretelui nazal lateral şi a sinusului etmoidal.

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 by 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.

Computed tomography of the head and paranasal sinuses is the gold standard for the diagnosis of oste­oma and is also necessary for its management. MRI is useful when intracranial extensions are suspected 8.

The management of the frontal sinus osteoma depends on the severity of the symptoms and the extension of the tumor. If chronic sinusitis unresponsive to treatmentpersistent headaches when all other causes have been excluded or mucocele occur, the therapeutic approach is surgical.

It can be external, endoscopic or combined: external for the removal of the tumor, and endoscopic to provide the appropriate drainage from the frontal sinus.

The approach depends mostly on the site and dimension of the osteoma. Sometimes, there are cases of small frontal recess osteomas which can be approached only by endoscopic approach. The definitive diagnosis of osteomas can be established only after the histological examination of the tumor. If osteoma is big, extending through the sinus wall to the intracranial space, a multidisciplinary surgical approach will be mandatory: otorhinolaryngologist and neurosurgeon.

papilloma nose and paranasal sinuses The postoperative complications which may occur are: subcutaneous emphysema, persistent suppurative sinusitis, fistulization, frontal osteomyelitis, supraorbitar nerve branches damage, supraorbitar neuralgia, ecchymosis, palpebral edema, dyplopia, epiphora, frontal recess stenosis, recurrence of frontal sinusitis, and tumoral recurrence. The current case had a classic, slow onset and progression, affecting a middle aged female patient.

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 head 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 papilloma nose and paranasal sinuses mentioned abovethe decision regarding the therapeutic approach was taken and the combined approach surgery was performed: external and endoscopic, which allowed the ablation of the tumor, as well as proper postoperative drainage of frontal sinus.

Due to the early diagnosis of the osteoma, no complications have been noticed, the evolution being favorable.

ENT postoperative reevaluations performed after one month, three months, six months and 12 months did not reveal any tumoral recurrence.
