Endoscopic medial maxillectomy in patients treated at the Otorhinolaryngology and Laryngological Oncology Clinic of Military Institute of Medicine in Warsaw in the years 2008-2018.

<b>Introduction:</b> Endoscopic medial maxillectomy (EMM) refers to surgical resection of the medial wall of the maxillary antrum. The primary indications for EMM are recalcitrant maxillary sinusitis, ablation of malignant and specific benign diagnoses such as Schneiderian Papilloma. Maxillectomy is potentially complicated by injuries to the orbital contents, lacrimal apparatus, optic nerve, ethmoidal arteries that may be accompanied by brisk bleeding. <br><b>Aim:</b> The purpose of this paper is to conduct a retrospective analysis of patients treated with EMM surgery at the Otorhinolaryngology and Laryngological Oncology Clinic of Military Institute of Medicine in Warsaw in the years 2008-2018. <br><b>Material and methods:</b> The retrospective analysis was conducted on patients who underwent EMM treated at the the Otorhinolaryngology and Laryngological Oncology Clinic of Military Institute of Medicine in Warsaw in the years 2008-2018. The research included 18 patients aged 15-94; 8 women and 10 men. <br><b>Results:</b> Out of 18 patients, 8 had been operated before EMM. 16 of them presented with histological examinations, though 5 of which were not confirmed with postoperative histological result. The most common indication for the operation was inverted papilloma. <br><b>Conclusion:</b> Endoscopic surgical approach is effective and precious way to manage tumors which involve the neighboring structures especially medial maxillary sinus. EMM itself is a safe surgical method in managing maxillary sinus disorders and is favored for its decreased invasiveness and avoidance of the deformity of face.
