Objective: The aim of this prospective clinical study is to evaluate the feasibility of the micro-laryngeal surgery (MLS) using a 3D operating exoscope (OE) in substitution to a conventional operating microscope (OM). Methods: A total of 41 consecutive patients were included (male: 26; median age: 55.0 years; IQR: 46.0-68.0). After each procedure, the surgeon and the scrub nurse were asked to fill out a tailored questionnaire on a 3-point Likert scale (1—not acceptable, 2—acceptable, 3—good) including 12 items. Results: The majority of the procedures were therapeutic (n = 31, 75.6%), while the remaining were diagnostic (n = 10, 24.4%). All surgeries were successfully completed without the support of the OM, and no complications or unwanted delays were detected. The majority of the individual items were judged “good” either by surgeons (n = 399, 81.1%) and scrub nurses (n = 287, 87.5%). The natural posture during the procedure, and the ease of use the joystick and focusing were the best-rated items by the surgeons. Conclusions: This study demonstrates the feasibility of MLS using the OE. Further comparative clinical studies are needed to clarify its real value in substitution to a conventional operating microscope and to better define advantages and disadvantages.

Summary Background/Aim: Hard palate fistulas are due to pathologies such as noma, syphilitic gom, leprosy, leishmaniasis, radiotherapy, removal of cysts or tumors of the sinus or palate, trauma or tooth attraction. Symptoms of palatal fistulas include hypernasality in the phonation due to nasal air escape during a speech, nasal cavity fluid flow, and infection due to food accumulation. Surgical repair of palatal perforations is technically difficult and complicated. Different surgical methods can be used depending on the size and location of the defect. Among these techniques, the locoregional flap types used are palatal flap, nasolabial flap, a buccal fat pad and tongue flap. Case Report: In this case report, we presented a patient with oronasal fistula due to a previous surgical operation, which was surgically closed by a palatal rotational flap. Conclusions: As a result, the oronasal communucation was relieved by successful closure of the defect and the donor area healed uneventfully.

Breast reconstruction after breast cancer is an emotional subject for women. Consequently, the correct timing and surgical procedure for each individual woman are important. In general, heterologous or autologous reconstructive procedures are available, both having advantages and disadvantages. Breast size, patient habitus, and previous surgeries or radiation therapy need to be considered, independent of the chosen procedure. New surgical techniques, refinement of surgical procedures, and the development of supportive materials have increased the general patient collective eligible for breast reconstruction. This review highlights the different approaches to immediate breast reconstruction using autologous or heterologous techniques.

Abstract An endoscopic approach through the transnasal corridor is currently the treatment of choice in the management of benign sinonasal tumors, cerebrospinal fluid leaks, and pituitary lesions. Moreover, this approach can be considered a valid option in the management of selected sinonasal malignancies extending to the skull base, midline meningiomas, parasellar lesions such as craniopharyngioma and Rathke cleft cyst, and clival lesions such as chordoma and ecchordosis. Over the past decade, strict cooperation between otorhinolaryngologists and neurosurgeons and acquired surgical skills, together with high-definition cameras, dedicated instrumentation, and navigation systems, have made it possible to broaden the indications of endoscopic surgery. Despite these improvements, depth perception, as provided by the use of a microscope, was still lacking with this technology. The aim of the present project is to reveal new perspectives in the endoscopic perception of the sinonasal complex and skull base thanks to 3-dimensional endoscopes, which are well suited to access and explore the endonasal corridor. In the anatomic dissection herein, this innovative device came across with sophisticated and long-established fresh cadaver preparation provided by one of the most prestigious universities of Europe. The final product is a 3-dimensional journey starting from the nasal cavity, reaching the anterior, middle, and posterior cranial fossae, passing through the ethmoidal complex, paranasal sinuses, and skull base. Anatomic landmarks, critical areas, and tips and tricks to safely dissect delicate anatomic structures are addressed through audio comments, figures, and their captions.

Background: The aim of the study was to describe our initial experience with the high-definition three-dimensional (3D) exoscope for middle ear surgery versus the operating microscope. Methods: The study included 60 randomly chosen patients diagnosed with otosclerosis (n = 30) or chronic otitis media (n = 30) with a clinical indication for surgery. The primary measurement was the subjective estimation of quality of the visibility of the operating field provided by the 3D exoscope—VITOM-3D (Karl Storz, Tuttlingen, Germany) in comparison to the operating microscope. Results: All procedures, except for two (3.3%) converted to the microscope, were successfully completed using a 3D exoscope. In both stapedotomy and tympanoplasty, the exoscope was superior to the microscope during more superficial portions of the procedures. By contrast, in deeper areas of the middle ear, the exoscope provided significantly worse visibility, but usually not suboptimal. Both intraoperative bleeding and the narrow surgical field substantially reduced the visibility with the 3D exoscope in comparison to the microscope. Conclusions: Overall, our study shows that the 3D exoscope offers excellent, highly magnified, and well-illuminated high-definition images of the surgical field. However, our experience revealed several important limitations of this system, including decreased depth perception in deep areas of the tympanic cavity and reduced visibility in a difficult surgical field, with subsequent need to switch to an operating microscope in select cases.

The knowledge of the hull shape and geometry of a racing vessel is one of the most important factors for predicting boat performance. The Offshore Racing Congress (ORC) rating system specifies the calculation parameters of the hydrodynamic forces of boat lift and drag on the basis of input data as the length of waterline while sailing, displacement, wetted surface and the volume distribution along the hull. It is represented by sophisticated calculations for national as well as international events and races. Measurement using a reflectorless total station in a coordinate system defined by the sailboat hull is the most established method approved by the ORC organisation. The determination of these geometric parameters by new, unconventional technologies, which should provide a quicker and more detailed measurement while preserving the quality and accuracy of results necessary for the handicap calculations was our main objective. Geometrical shapes of a cabin sailboat hull were determined by the technology of terrestrial laser scanning and two methods of digital close-range photogrammetry—convergence case of photogrammetry and Structure-from-Motion (SfM) method. High-Definition Surveying (HDS) targets for laser scanning and coded targets for digital photogrammetry were used throughout all methods in order to transform the resulting data into a single local coordinate system. The resulting models were mutually compared by visual, geometrical and statistical comparison. In conclusion, both technologies were considered suitable, however, with various advantages and disadvantages. Nevertheless, although labour intensive, the SfM photogrammetry can be considered the most suitable method if the correct procedures are followed.
