“…[4][5][6][7] It is believed that the mechanism of action of formalin treatment is desiccation and coagulation of the tissue. 4 Documented adverse effects following formalin injection for treatment of ethmoid hematomas have included laminitis 4 and sudden onset of acute fatal neurologic signs. 8 However, fewer adverse effects were reported with intralesional administration of formalin, compared with intralesional administration of silver nitrate or administration of chlorhexidine.…”

Summary Progressive haematomata (PH) are a rare cause of equine paranasal sinusitis and are thought to result from recurrent haemorrhage within the respiratory submucosa of the ethmoidal labyrinth. Clinical signs of PH are variable but mostly attributable to rupture of the mass with haemorrhage, occlusion of nasomaxillary drainage and secondary infection. Almost all affected horses have unilateral or bilateral, intermittent, serosanguinous nasal discharge. Radiographic examination is useful in identifying large PH, but small masses can be overlooked because of superimposition. Computed tomography (CT) has the benefit of producing cross‐sectional images of the sinuses, overcoming the limitations of radiography. The cases in this report suffered from bilateral PH not associated with the ethmoidal labyrinth. They highlight the benefit of CT in the diagnosis, surgical planning and evaluation of the architecture of the sinuses. Preoperative treatment with formalin to desiccate the mass prior to removal can be performed more safely when guided by CT.

“…Bei einer weiteren Methode soll das Tumorgewebe durch eine transendoskopische Injektion einer 4o/o Formaldehyd-Lsg zurückgedrängt werden (Schuhmacher et al, 1998). Größere Tumoren oder Tumoren, die ihren Ursprung im Bereich der Nasennebenhöhlen finden, lassen sich häufig nur durch eine Flap-Operation vollständig entfernen (Tate, 1991;Colbourne et al, 1997).…”

ZusammenfassungDurch transendoskopische Operationsverfahren (minimal invasive Chirurgie: MIC) lassen sich die Risiken von chirurgischen Maßnahmen im Bereich der oberen Atemwege des Pferdes reduzieren. Allerdings sind nicht alle Erkrankungen mit dieser Technik befriedigend therapierbar. Zum Einsatz kommt eine kostenaufwendige Technik, die ein Endoskop mit Videosystem, diverse transendoskopische Instrumente, ein Hochfrequenzchrrurgiegerät und einen Chirurgielaser beinhaltet. In den oberen Atemwege können damit Erkrankungen der Nasengänge, der Nasenmuscheln und der Nasennebenhöhlen, der Luftsäcke, des Pharynx und des Larynx behandelt werden. Die transendoskopische Chirugie ist besonders geeignet bei der Behandlung von kleineren Nasengangs-und Siebbeintumoren, bei der Therapie von Luftsackerkrankungen (Abszess, Tympanie, Mykose) und bei der Entfernung von Subepiglottiszysten. Bei der Therapie der Dorsalverlagerung des Gaumensegels und des Epiglottis-Entrapment sind transendoskopische OP-Verfahren eine gute Alternative zu konventionell chirurgischen Verfahren. Die endoskopische, partielle Resektion der Stimmfalte bei einer Kehlkopflähmung stellt eine komplikationsarme Ergänzung zu bestehenden Operationsmethoden (Ventrikelektomie und Laryngoplastik) dar, durch die in vielen Fällen eine ausreichende Leistungssteigerung erzielt werden kann.Schlüsselwörter: Minimal invasive Chirurgie, Endoskopie, Laser, obere Atemwege, Pferd Possibilities and limitations of minimal invasiv surgery in upper airway diseases of the horse Through the use of transendoscopic operative techniques (minimal invasiv surgery) it is possible to reduce the risks associated with surgical procedures of the upper respiratory tract. lt is, however, not possible to satisfactorily treat all cases with this technique. The technique is expenstve, and involves the use of an endoscope with a video system, various transendoscopic instruments, a high{requency generator and a surgical laser. Its appltcation in the upper respiratory tract includes the treatment of diseases of the nasal passages, the ethmoid turbinates and the sinuses, as well as the guttural pouches, the pharynx and the larynx. Transendoscopic surgery is particularly well suited for the treatment of small nasal passages tumors and ethmoid hematomas, in the therapy of guttural pouch abscess, tympany and mycosis and in the removal of subepiglottic cysts. In the treatment of the dorsal displacement of the soft palate and in epiglottic entrapment the transendoscopic operative technique represents a sound alternative to conventional surgical techniques. The endoscopic, partial resection of the vocal fold in the case of Hemiplegia laryngis represents an uncomplicated addition to the already establishedtechniques (ventriculectomy and laryngoplasty), through which in many cases, a sufficient increase in performance can be achieved. keywords:Einleitung
