The Lamella Ostium Extent Mucosa (LOEM) system: a new classification and pilot study for endoscopic sinus surgery.

Purpose: This study proposes the Lamella Ostium Extent Mucosa (LOEM) system as a compact and user-friendly classification for endoscopic sinus surgery (ESS), based on surgical bone extension and mucosal management, aiming to resolve inconsistencies in describing surgical techniques and extension levels, and to enhance comparability of outcomes in chronic rhinosinusitis (CRS).

Methods: LOEM uses a lettering system representing a specific topographical level: L identifies the lamellae, O the ostia, E the opening of the sinus walls, and M the mucosal approach. Eleven CRS surgical cases were independently evaluated by seven rhinologists following a Delphi method in two consecutive rounds.

360° around the orbit: key surgical anatomy of the microsurgical and endoscopic cranio-orbital and orbitocranial approaches.

Objective: Several pathologies either invade or arise within the orbit. These include meningiomas, schwannomas, and cavernous hemangiomas among others. Although several studies describing various approaches to the orbit are available, no study describes all cranio-orbital and orbitocranial approaches with clear, surgically oriented anatomical descriptions.

Assessing the effect of absorbable steroid sinus implant: a state-of-the-art systematic review.

Objectives: Endoscopic sinus surgery is not a definitive treatment for chronic rhinosinusitis (CRS). The use of sinus stents after surgery to maintain sinus patency and deliver local steroids has gained popularity. The first steroid-eluting bioabsorbable implant (SEBI) approved for this indication, later Propel, was developed in 2011.

Coblator adenoidectomy in pediatric patients: a state-of-the-art review.

Introduction: Adenoid hypertrophy is one of the main causes of nasal obstruction in 'children. Adenoid hypertrophy can be approached either with nasal corticosteroids, or surgically when medical treatment fails. Different adenoidectomy techniques have been proposed to reduce morbidity and surgical risks, with a consequent marked increase in the use of new surgical procedures in recent years, with a progressive increase in the use of coblation.

Endoscopic-assisted en-bloc pterygomaxillectomy: Identifying an efficient and safe location for the pterygoid osteotomy.

Background: For aggressive maxillary sinus and pterygopalatine fossa (PPF) tumors, an en-bloc pterygomaxillectomy may be indicated.

Methods: Five head specimens were used to study the feasibility of an en-bloc pterygomaxillectomy. Eighty-five non-pathological CT scans were used to compare the superior edge of the inferior turbinate (IT) and the middle turbinate tail (MT) as landmarks for the pterygoid osteotomy.

[A simple and reliable technique for the treatment of rhinoliquorrhoea from small defects: Free nasal mucosa overlay graft].

Introduction: Cerebrospinal fluid leaks to the sinonasal cavities (rhinoliquorrhoea) represent a process with diagnostic and therapeutic difficulties. The endoscopic transnasal approach is the method of choice, but with many possible variants. The purpose of this paper was to make a critical review of our diagnostic and therapeutic protocol used for 11years.
