OBJECTIVE Nasal encephalocele may presents as a nasal mass, its treatment is surgical and it should be done early in life. When removal is indicated, there are multiple surgical approaches; including lateral rhinotomy, a transnasal approach and a coronal flap approach. However, the treatment of a basal intranasal encephalocele using transnasal endoscopic approach could obviates the possible mor...

OBJECTIVES/HYPOTHESIS Nasolabial cysts are rare nonodontogenic cysts arising commonly in the nasal alar region. Intraoral sublabial resection of nasolabial cysts is considered the standard treatment modality. In the past 16 years, transnasal endoscopic marsupialization has emerged as an alternative approach for these lesions. A systematic review on this entity was performed to evaluate manageme...

Transnasal endoscopic orbital decompression is a viable alternative for external orbital decompression. Today, it can be performed due to the great development of endoscopic technology and specific endoscopic surgical instruments. It requires strong anatomic knowledge and skilled hands. We present our experience with endoscopic orbital decompression focusing on the surgical technique used in ou...

BACKGROUND Nasolacrimal duct obstruction is caused by a variety of acquired and congenital etiologies. The standard treatment is dacryocystorhinostomy (DCR), with the gold standard being the external DCR. Since the advent of the nasal endoscope, the transnasal endoscopic DCR has gained popularity and has several advantages over the external approach. Some potential advantages include the avoida...

Since its original description in 1907, surgery of the pituitary gland has undergone a remarkable evolution. While open transphenoid approaches gained interest, they were mostly abandoned in favour of craniotomy because of concern of inadequate tumour resection. However, with widespread use of antibiotics in the 1950s and introduction of surgical microscope in the 1960s, the transphenoidal appr...

BACKGROUND Surgical approaches for many tumours are often limited by blood loss, exposure and risk to vital anatomical structures. Therefore, the standard of care for certain skull base tumours has become endoscopic transnasal resection. Other surgical disciplines often use cell salvage techniques, but review of the otolaryngology literature revealed very few case reports. This study investigat...

INTRODUCTION Choanal atresia is a rare congenital malformation of the nasal cavity characterized by the complete obliteration of the posterior choanae. In 67% of cases choanal atresia is unilateral, affecting mainly (71%) the right nasal cavity. In contrast to the unilateral form, bilateral choanal atresia is a life-threatening condition often associated with respiratory distress with feeding a...

INTRODUCTION Malignant tumors of the paranasal sinuses are traditionally managed through external approaches. Advances in endoscopic transnasal surgery have allowed for the endoscopic treatment of some of these tumors. AIM To present the results of treatment of a series of patients with paranasal sinus malignancies treated with an endoscopic approach at a single institution. MATERIAL AND ME...
