Minimally invasive treatment of sino-nasal aspergillosis

  1. The canine fossa trephination (CFT) procedure is a highly effective means of clearing diseased material from all areas of the maxillary sinus and is especially useful in patients with Sampter's triad and fungal sinusitis. However, many surgeons have failed to adopt this technique for fear of its potential complications
  2. In 54 per cent of dogs, the frontal sinus depth measured less than or equal to 2 cm at one or more of the landmarks. Sinus entry at the deepest point will reduce the risk of accidentally damaging underlying structures. This may be approximately 1 cm caudal, in breeds of dog that typically develop aspergillosis, to a previously suggested landmark
  3. or surgical procedure is appropriate sedation of the horse (usually detomidine and butorphanol), clipping of the hair, surgical preparation of the portal site, and infiltration of 5-6 mls of local anesthetic subcutaneously at the portal site. The size of the portal made will be.
  4. Sinonasal aspergillosis is an uncommon, yet debilitating and often frustrating condition to treat in dogs despite years of research evaluating pathogenesis, diagnosis and treatment. The disease is most commonly caused by non-invasive fungal infection, thought to be secondary to altered innate and/or adaptive immune responses

Aspergillus fumigatus is a common cause of rhinitis and sinusitis in dogs and has been found in 12%-34% of dogs evaluated for chronic sinonasal disease. 1 - 5 Diagnosis is confirmed by a combination of rhinoscopy, computed tomography (CT), cytology or histology, fungal culture, and serology. 2 - walls of the frontal sinus were thickened, irregular, and heterogenous. Based on the computed tomography findings, fibrous dysplasia or fungal rhinosinusitis was suspected. The dog was anesthetized for frontal sinuses trephination to collect samples of the mass for biopsy. The dog was euthanized after a prolonged anestheti

In dogs, nasal neoplasia is nearly always malignant, and adenocarcinoma is the most common tumor type. 4,33,81 The average age at diagnosis is approximately 10 years, and medium to large breeds appear to be overrepresented. 4,167,194 Despite the locally aggressive nature of nasal neoplasia in dogs, the rate of metastasis is low; when metastasis. Certain species of a common fungus called Aspergillus can infect the nasal cavity and sinuses of dogs, and can even become disseminated to different areas of the body. Dogs affected by exposure to this fungus are usually immunosuppressed. Diagnosis of either form, the nasal form or disseminated form can be difficult, usually requiring X-rays or more advanced imaging such as MRI or CT, as well.

  2. The dog was euthanized after complications during a trephination and biopsy procedure. At necropsy, a large, tan, papillary, gelatinous mass filled the entire nasal cavity and frontal sinus. The mass was composed of large fronds of loose fibrovascular stroma covered by a single layer of pseudostratified, columnar, ciliated epithelium and.
  3. Chronic nasal discharge is a common clinical sign of disease in dogs. Sneezing and nasal discharge are the primary signs of sinus, nasal, and/or nasopharyngeal disorders in the dog. The type of discharge (serous, mucoid, purulent, hemorrhagic), the onset and duration of the nasal problem, and response to therapy should be evaluated
  4. Rhinitis or sinusitis may result when an apical tooth root abscess extends into the maxillary recess. Mycotic rhinosinusitis may be caused by Cryptococcus neoformans, Aspergillus spp, and Penicillium spp. Cats are more often affected with Cryptococcus spp than dogs, whereas aspergillosis is frequent in dogs but rare in cats

12 Revision Maxillary Sinus Surgery including Canine Fossa Trephination Marc A. Tewfik, Simon Robinson, and Peter-John Wormald One of the keys to achieving successful outcomes from functional endoscopic sinus surgery (FESS) is controlling disease within the maxillary sinus. Depending on the disease process present, different approaches are required to achieve this Performing frontal sinus curettage in a dog with sinonasal aspergillosis Aspergillus fumigatus is a saprophytic fungus that affects dogs in many geographic locations throughout the United States, including Nebraska. Sinonasal aspergillosis typically occurs in dolichocephalic breeds, affecting both nasal passages and paranasal sinuses This video describe an experimental operation in Donkey for Frontal sinus Trephination in our faculty of veterinary Medicine SVU _Qina Egyp The trephining of the canine fossa can be performed sublabially. After successful trephination using the trocar has been performed the opening can be widened using a burr. The opening should be wide enough to permit insertion of a 4 mm nasal endoscope. The maxillary sinus can be visualized from both angles i.e via the natural ostium using a 70.

Clinical signs of sinus disease can include nasal discharge (usually unilateral and can be malodor-ous), facial deformity, and respiratory noise.1,2 Sinusitis can be subdivided into two groups: pri-mary and secondary. Primary sinusitis can be of either bacterial or viral etiology. Secondary sinus-itis includes conditions such as paranasal sinus Conclusions and Clinical Relevance—Results confirm that frontal sinus involvement is common in dogs with nasal aspergillosis and suggest that frontal sinus trephination and sinuscopy may aid in the diagnosis of aspergillosis in dogs, particularly dogs with rhinoscopic evidence of destructive rhinitis and computed tomographic evidence of sinus. Trephination of frontal sinus is a surgical procedure where in a small opening is made in the floor of frontal sinus facilitating drainage of its contents. Trephination of frontal sinus is nothing new. It dates back to prehistoric times. Two Peruvian skulls at the Museum of Man in San Diego show evidence of frontal trephination 1 In dogs, SNA is a subacute to chronic, noninvasive disease of the nasal cavity and sinuses. It is most often caused by Aspergillus fumigatus. Rarely, infection by other species, such as Aspergillus niger complex organisms (such as Aspergillus tubingensis) or Aspergillus flavus and the closely related fungus Penicillium, occurs

sinus can be achieved faster and more completely via a canine fossa trephination approach than a purely trans-nasal approach. •Fewer microdebrider blades are used with the canine fossa trephination approach •In a training setting, the canine fossa trephination approach appears to have a faster learning curv Lymphocytic-plasmacytic rhinitis (L-PR) is a nonspecific inflammatory condition associated with antigenic and irritant stimulation. This disorder is most commonly found in dogs. and has a predisposition for Dachshunds. The clinical signs are those commonly seen with nasal diseases, including sneezing and nasal discharge of varying character Sinusitis is treated by draining the affected sinus. Trephine sites should be selected carefully, using appropriate anatomic landmarks. If an infected tooth is the cause of maxillary sinusitis, the tooth can be repelled through a sinusotomy site created with a trephine Two reports describe 3 dogs with cribriform lysis that were treated with topical enilconazole with no apparent complications.8, 9 In another report, 2 dogs with minor cribriform plate involvement also were treated topically with 1% clotrimazole solution without apparent complications.6 The extent of cribriform or frontal sinus involvement and. Dogs rooting around in leaf mulch and damp earth can inhale the fungal spores, and the spores can then incubate and infect your dog's nasal chambers, resulting in clinical aspergillosis. The symptoms of infection include a yellow-green nasal discharge from one nostril that does not respond to antibiotics, tenderness when the face or nose is.

Frontal sinus osteomyelitis is seen in as many as 80% of dogs. Cross-sectional imaging via CT is more sensitive than plain radiographs in demonstrating consistent changes. Visualization of fungal plaques by rhinoscopy together with serologic and either mycologic or radiographic evidence of disease is often how a diagnosis is made The objective of this study was to determine the feasibility of trephination of the frontal sinus and injection of antifungal cream using a medical bone marrow drill in dogs. Results were compared with frontal sinus trephination using a standard surgical technique

Planning for the canine fossa trephination approach

Frontal sinus trephination is typically needed to evaluate the sinuses, and is recommended in dogs with sinus involvement on CT/MRI. Cytology and histopath for aspergillosis? ID fungal hyphae. Collection technique CRITICAL. Impression smears and blind stuff have low sensitivity. BEST IDed cytologically using mucosal brushings or impression. Trephination in the field is most valuable for those owners who are open to surgery for a condition with a good to excellent prognosis, as with sinus cysts. Surgical debridement of the cyst lining is curative and airflow through an effective nasal passage may improve through remodeling, although the deformity will still be visible fine-needle aspiration, sinus trephination, and rhinoscopy-assisted mucosal biopsies.1-8 A successful diagnosis may depend on tissue volume obtained.1 A relatively noninvasive technique to obtain a larger portion of tissue may help improve diagnostic accuracy. In this report, the authors describe a hydropulsion method of forcefu Objective: 1) To assess how much of the maxilary sinus could be accessed through a 5-mm endoscopic canine fossa trephination (eCFT) in a cadaveric model. 2) Review the clinical benefits as well as co-morbidities associated with this procedure. Method: A cadaveric study involving 6 fresh-frozen heads that underwent endoscopic sinus surgery giving 12 sides. eCFT was performed and heads were.

Use of noninvasive intranasal infusion of clotrimazole eliminates the need for surgical trephination of frontal sinuses in many dogs and was associated with fewer complications (Mathews et al, 1998). In this study, twenty-seven dogs were anaesthetized and treated with 1 topical administration of clotrimazole delivered via surgically placed. Trephination (known also as trepanning, trepanation, trephining, or making a burr hole), is a surgical procedure, which involves the drilling of a hole in the skull of a living person. Trephination is considered to be one of the oldest surgical procedures in the world, and evidence for this practice is found as early as the Neolithic period a 5mm endoscopic canine fossa trephination •Chronic Rhinosinusitis (CRS) is a common clinical condition affecting up to 15% of the population with a significant burden on health care systems with estimated costs of $5.8 billion. •Endoscopic sinus surgery is the gold standard surgical treatment

Such procedures may be necessary when the frontal sinus cannot be reached endoscopically. Frontal sinus trephination is a quicke BACKGROUND: Sino-nasal aspergillosis is a common nasal disease in dogs. Recommended treatment protocols typically involve trephination of the frontal sinuses or the use of an antifungal solution instilled into the frontal sinus under anesthesia, both of which have associated morbidity and complications

Common Conditions. One of the most common diseases of the sinuses is sinusitis, which is an infection, usually of all the sinus cavities on one side of the horse's head.There are two major causes of this infection. One is primary sinusitis, in which a bacterial infection invades the delicate lining of the sinus and causes a build-up of pus in the sinus cavity Bilateral frontal sinus trephination and right transfrontal craniotomy revealed clear, viscous fluid in the right frontal sinus and rostral fossa, compatible with an intracranial mucocele. At a 6-month follow-up exami- In dogs, each frontal sinus is composed of three separate cavities (i.e., lateral, medial, and rostral) Conclusions and Clinical Relevance - Results confirm that frontal sinus involvement is common in dogs with nasal aspergillosis and suggest that frontal sinus trephination and sinuscopy may aid in the diagnosis of aspergillosis in dogs, particularly dogs with rhinoscopic evidence of destructive rhinitis and computed tomographic evidence of sinus. Creation of a canine fossa trephination (CFT) permits a more direct approach than removal via the maxillary ostium.
