To attain without compromise the surgical goal, a straight and concurrently solid septum, especially in cases of marked deviations or severe post-traumatic deformities (sometimes combined with external deformities), an excellent proven and well-known technique is extracorporal or external septoplasty. Surgery consists of excision of the quadrilateral cartilage and its division into straight fragments. To avoid postoperative sequelae such as saddling, the pieces of cartilage must be reconnected meticulously to form a straight and at the same time solid plate. This difficult and time-consuming procedure can be assisted by the use of a connecting material. Since 1996 we have been using a polydioxanone foil (PDS, Ethicon Norderstedt Germany) as the supporting material for this purpose. The PDS as well as the suture material is completely resorbed within 5 months, excluding long-term complications of other artificial implants.

Nasal airway obstruction is a frequent complaint in an otolaryngology clinic and is often multifactorial. Anatomic contributors may include a nasal septal deviation, inferior turbinate hypertrophy, and nasal valve compromise. Septoplasty and inferior turbinate reduction are one of the most common procedures performed by an otolaryngologist.

Background: Sinonasal malignancies, in which squamous cell carcinomas are the most common are rare and difficult to treat given the location and anatomical structures involved. Sinonasal malignancies often present late due to non-specific and benign symptoms. Partial resections are often associated with poorer outcomes [1].

Background: Electrocardiographic imaging (ECGi) is a non-invasive technique for ventricular tachycardia (VT) ablation planning. However, it is limited to reconstructing epicardial surface activation. In-silico pace mapping combines a personalized computational model with clinical electrocardiograms (ECGs) to generate a virtual 3D pace map.

Objective: Repositioning and fixation of the posterior septal angle (PSA) relative to the anterior nasal spine (ANS) is a well-known maneuver performed during rhinoplasty. Suture techniques through the periosteum along with transosseous drilling through the spine are the two most common fixation methods. We report on how nasal airway patency varies as a function of technique and patient demographic factors.
