Papilloma nasal pathology


Corelaţii anatomoclinice şi imagistice CT în patologia rinosinuzală. Source: ORL. We begin by presenting the normal anatomic structures and anatomic variants on CT imaging. Particular CT scan aspects of each paranasal sinus are presented. The author is focused on anatomical, clinical and imagistic correlations of the rhinosinusal pathology malformations, inflammatory, benign or malignant tumorswhich are very important for the preoperative imagistic diagnosis and surgical therapeutic indication.

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 papilloma nasal pathology the complete visualization and access to the maxillary sinus.

The authors papilloma nasal pathology, as an endoscopic surgical atlas, step by step, the surgical procedure for endoscopic approach of inverted papilloma, in order papilloma nasal pathology 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 papilloma nasal pathology a peretelul nazal lateral şi a sinusului maxilar. Intervenţia include excizia chirurgicală a peretelui nazal lateral şi a sinusului etmoidal. Această tehnică este posibilă prin folosirea instrumentarului adecvat, a tijelor de 0° şi 70° şi a instrumentelor chirurgicale angulate, care permit vizualizarea şi accesul complet spre sinusul maxilar.

These often lead to deformities in the jaw area. Cases are specific by framing pathological rarity, etiology, pathogenesis and clinical symptoms. Considering the large entity of cystic formations that can be found in the maxilla region, we selected two patients with cystic formations of the upper jaw, which were part of different pathological etiology categories, with special rarity occurring, evolutionary appearance and difficult to classify in terms of pathognomonic signs.

Autorii prezintă, ca un atlas de chirurgie endoscopică, paşii acestei tehnici chirurgicale de abord endoscopic al papilomului inversat, în vederea exciziei complete a tumorii, fără nicio restanţă. Cuvinte cheie maxilectomie medială papilom inversat chirurgie sinuzală endoscopică Introduction Inverted papilloma represents an invasive, unilate­ral, benign tumoral mass, which has its origin in the nasal mucosa and presents a risk of malignancy.

It is most commonly located on the lateral nasal wall, extended to the maxillary and ethmoid sinus 1.

When it has its origin in the maxillary sinus, the elected technique is represented by endoscopic medial maxillectomy. Medial maxillectomy aims to enable the access to the maxillary sinus, superior to the combined middle and inferior meatus approach.

In the last decades, with the development of endoscopic and imagistic techniques, the endoscopic papilloma nasal pathology replaced the external procedures, as it presents similar success rates, lower morbidity and better esthetic outcomes for the patient 2. Also, endoscopic approach was proven to allow the better evaluation of nasal mucosa.

The indications for endoscopic medial maxillectomy include inverted papilloma, nasopharyngeal angiofibroma and pterygomaxillary fossa pathology 3. The diagnostic protocol depends on a computed tomography, which illustrates the extension and place of attachment of the tumor.

Figure 1. CT image, coronal section, showing complete blockage of papilloma nasal pathology maxillary sinus, hyperostosis and tumoral origin arrow The first surgical step includes antero-posterior ethmoidectomy, with the excision of the tumor from this level and from the middle meatus.

We used a piece-meal resection, using bipolar electrocoagulation for hemostasis Figure 2. Figure 2.

Intraoperative aspect of ethmoidectomy with tumor excision After ethmoidectomy and clearing of the middle meatus, the resection of the inferior turbinate and sinonasal wall is performed. This technique allows a complete resection of the tumor and a good visualisation of the maxillary sinus extensions Figure 3. Figure 3. Endoscopic resection of the inferior papilloma nasal pathology and papilloma nasal pathology nasal wall Medial maxillectomy offers an optimal access to the maxillary sinus, with the complete resection of the tumor and the identification of the tumor origin.

We can succeed in this procedure using an angulated curette Figure 5 or an angulated diamond burr, depending on the position of the bony stalk or hyperostosis. Figure 5.

Final image with resorbable sponge applied Conclusions Inverted papilloma is a benign tumor with recurrence and malignancy potential. Recurrence is in fact a tumoral residue. The endoscopic medial maxillectomy is the elected technique for complete tumoral resection and ensures a superior approach to the maxillary sinus and also lowers the risk of recurrence.
