Maxilectomia maxilară medială pentru papilomul inversat
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. Although the surgical staff has a lot of experience in doing the endoscopic transnasal approach, there are some cases where the transnasal route cannot safely solve certain pathologies.
This is the inverted papilloma why the authors wish to illustrate the need of using an approach that will ensure a proper management of any kind of complications that can occur during surgery, specific to these tumors bleeding, cerebrospinal fluid leak.
In this case, the transcranial endoscopic approach was the best solution. Keywords frontal sinus, tumor, external endoscopic approach Rezumat Prezentăm cazul unui pacient, în vârstă de 62 de inverted papilloma, cu o formaţiune tumorală voluminoasă de sinus frontal bilateral, cu sindrom cefalalgic sever şi distrucţia parcelară a laminei papiracee stângi şi a peretelui posterior al sinusului frontal drept.
Endoscopic medial maxillectomy for inverted papilloma
Abordul endoscopic inverted papilloma efectuat printr-o fereastră intersprâncenoasă de mici dimensiuni, cu refacerea suportului osos la finalul intervenţiei utilizând o plasă din titan. Deşi echipa chirurgicală are o experienţă îndelungată în abordul transnazal endoscopic, există cazuri în care parcursul transnazal nu poate rezolva în deplină siguranţă anumite patologii.

Cuvinte cheie sinus frontal tumoră abord endoscopic extern A year-old patient, S. Three years ago Mayin another ENT service, the patient underwent a curative surgery for bilateral fronto-ethmoido-sphenoidal rhinosinusitis.
Transcranian endoscopic approach in a frontal polyposis
According to the medical discharge presented by the patient, the frontal sinus approach used was of the Draf I kind, without exploring the frontal sinus cavity. The prolonged evolution led to a lysis of a wall caused by a decubitus injury. This explained the intimate tumoral contact with the dura mater through an 8-mm bone breach in the posterior wall of the right frontal sinus.
Also, the tumor protruded through the left orbit by an erosion of the left lamina papyracea, inverted papilloma the appearance of a discrete inferior and external exophthalmia inverted papilloma the left eye. The MRI revealed that the dura mater was integral and the orbital periosteum was apparently free Figure 1.

Figure inverted papilloma. Down: partial destruction of the left eye lamina papyracea, bone breach to anterior cerebral fossa The apparent origin located at the posterior wall of the bilateral frontal sinus, the partial exposure of the dura mater and the destruction of the lamina papyracea with the penetration inverted papilloma the tumor into the left orbit led to the decision inverted papilloma an external endoscopic approach.
We underwent the surgery using inverted papilloma anesthesia with OT intubation.
Skin incision: 20 mm, bone fenestration with 13 mm horizontal diameter and 10 mm vertical diameter. A hard inverted papilloma was shown upon palpation, with a macroscopic aspect of an inverted papilloma, well-vascularized, that occupied both frontal sinuses and dived through the nasofrontal ducts in the anterior ethmoidal cells.
Inverted papilloma apparent origin of the tumor inverted papilloma located at the junction between the posterior wall of the left frontal sinus and the intersinusal septum, in the upper floor of the sinus cavity.
There was a partial exposure of the dura mater and the left orbital periosteum, but there was no signs of penetration at their level. A Draf II transnasal endoscopic approach was performed for the restoration of ventilation in both frontal sinuses.
Radiofrequency hemostasis — fulfuration 10 W. Efficient hemostasis; did not inverted papilloma nasal package.

Intraoperative macroscopic aspect — optics. Restoration of bone support using titanium mesh A CT scan using a contrast substance was performed at the end of the surgery Figure 3.
It confirmed the complete macroscopic resection of the tumor and a wide ventilation of both frontal sinuses. Figure 3.

Up: postoperative CT aspect — axial, sagital. IHC inverted papilloma the diagnosis of a glandular subtype of sinus inflammatory polyp. We presented this case to point out that there are many situations when the pathology of the frontal sinuses still requires an external approach, even when we consider that the surgical team has a strong experience in transnasal endoscopic surgery.
The peculiarity of the case was the small bone-window through which the tumor inverted papilloma resected, the advantage we had being given by the usage of optics and angular tools that inverted papilloma papilloma the resection complete and safe for the patient.
CSF leaks, the frontal sinus osteomas that exceed the diameter of the nasofrontal duct and large solid tumors can be safely managed for the patient through a minimally invasive transcranial endoscopic approach inverted papilloma is lesion-centered.
