Partial resolution of chronic unilateral sinonasal obstructive disease in a cat using a temporary polyvinylchloride stent

Case summary A 3-year-old male neutered domestic shorthair cat presented for further investigation of a swollen left eyelid and a hard, non-painful bony swelling over the left frontal sinus. Physical examination revealed no nasal discharge or airflow through the left nostril. A CT of the head revealed a left frontal sinus obstruction with expansile remodelling and osteolucency. Drainage of the frontal sinus obstruction was alleviated via placement of a temporary polyvinylchloride (PVC) stent that was left in place for 6 weeks. Purulent material removed from the frontal sinus returned a positive culture for Pseudomonas aeruginosa susceptible to marbofloxacin that was continued for 4 weeks, and for an additional 2 weeks after stent removal. A left-sided mucoid nasal discharge returned 3 months after removal of the stent. Repeat CT performed 20 months after surgery found the presence of a gas-filled frontal sinus and partial resolution in the amount of fluid within the mid and rostral nasal cavity. A repeat positive culture for P aeruginosa was also obtained. The exact cause of the chronic unilateral sinonasal obstruction remains unclear, but an underlying chronic rhinitis with secondary obstructive frontal sinusitis or sinus mucocoele with secondary nasal extension was suspected. Relevance and novel information Chronic rhinosinusitis in cats can be a challenging condition to treat and cure. This case illustrates the partial resolution of chronic unilateral sinonasal obstructive disease in a cat using a temporary PVC stent.

Abstract Background The anatomical variation of the frontal sinus and its intimate relation to the skull base and orbit makes its surgery demanding. The extended endoscopic frontal sinus surgery allows wide better drainage and preventing the recurrence of the disease. Fourteen patients underwent EEFSS from May 2017 to May 2019. These patients are nine patients presented by chronic recurrent frontal sinusitis, three patients presented by chronic recurrent fronto ethmoidal mucocele and two patients with chronic recurrent external frontal fistula. Draff III done for ten patients of them and Draff IIB done for four patients of them. This study is designed for evaluating the efficacy of the extended endoscopic frontal sinus surgery (E E F S S) in management of chronic and recurrent frontal sinus diseases. Results The neo opening of the restored frontal sinus was remained opened with Draff III with high success rate; two patients from four patients with Draff IIb were with closed nasofrontal duct. The main follow-up was 12 months; the patients were followed up post-operatively for many office visits without any other manifestations. Conclusion The chronic recurrent frontal sinus diseases can be treated successfully with extended endoscopic frontal sinus surgery (E E F S S). The extended endoscopic frontal sinus surgery (Draff III) provides good results with low morbidity and less post-operative care.

The Relationship

Objective: The agger nasi cell (ANC) is an easily identifiable landmark when approaching the frontal sinus. The success of endoscopic frontal sinus surgery may be influenced by the width of the frontal recess (FR). The aim of this study is to examine the relationship between the FR width and the ANC size in Japanese patients. In addition, the effect of various frontal recess cells (FRCs) on the development of frontal sinusitis has been examined. Materials and methods: Multiplanar computed tomography (CT) scans of the nasal cavities and paranasal sinuses in 95 patients (190 sides) before endoscopic sinus surgery were reviewed. The presence of FRCs, the thickness of the frontal beak (FB), the ANC size, and the anterior-to-posterior (A-P) length of the frontal isthmus (FI) and FR were evaluated in patients with and without frontal sinusitis. Results: The prevalence of the ANC, frontal cell types 1, 2, 3, and 4, frontal bullar cell (FBC), suprabullar cell, supraorbital ethmoid cell, and interfrontal sinus septal cell was 85.3%, 11.6%, 0%, 7.9%, 0%, 25.3%, 45.8%, 16.8%, and 15.3%, respectively. The ANC volume showed a significant positive correlation with the A-P length of the FI and FR. The incidence of frontal sinusitis in the patients with FBCs was significantly higher than that without FBCs. Conclusion: A large ANC offers a greater potential to facilitating the approach to the frontal sinus because of the extensiveness of the FR in Japanese patients. The presence of FBCs may be related to a higher incidence of frontal sinusitis.

Agger nasi cells contribute to nasofrontal duct (NFD) obstruction and chronic frontal sinus disease. To investigate this relationship, we conducted a review of the surgical outcome and computed tomographic imaging in 26 patients with chronic frontal sinusitis. Coronal and sagittal images were used to delineate the anatomic variability and mucosal disease in the NFD and frontal sinus region. Data from coronal and sagittal images were compared. The results were also correlated with the outcome of frontal sinus surgery in patients with a clinical history of chronic frontal sinus disease. Our data suggest that agger nasi cell pneumatization with narrowing of the frontal sinus outflow tract is a significant cause of persistent frontoethmoid pain and chronic frontal sinusitis. Sagittal reformatted images are more capable than coronal images of demonstrating agger nasi cell encroachment on the NFD, as well as NFD mucosal disease. Endoscopic frontal sinusotomy is an effective treatment for chronic frontal sinus disease.

Case summary A 13-year-old female domestic longhair cat was presented for further investigation of chronic sneezing combined with a right-sided nasal discharge. A CT scan of the head revealed a locally invasive, aggressive right nasal mass radiographically consistent with a malignant neoplastic process. Histopathology on rhinoscopically guided biopsies revealed an unusual pathology consistent with fibro-osseous hyperplasia/dysplasia. Surgical treatment via a ventral rhinotomy and curettage was performed, and the diagnosis confirmed by repeat histopathology. The cat’s clinical signs significantly improved postoperatively. Relevance and novel information This case report describes an unusual feline nasal pathology. To our knowledge, there are no previous reports of a non-neoplastic, non-inflammatory expansile feline nasal tumour. Also described are the CT and histological appearance of the mass, and the difficulties encountered obtaining the definitive diagnosis. Information regarding the prognosis following surgical removal of proliferative fibro-osseous lesions in cats is poor, especially from the nasal cavity where clean margins may well be impossible to obtain. In this case, surgical resection improved clinical signs and the cat remains well at 15 months post-procedure.

Objective. Determining the indications for osteoplastic frontal sinus obliteration (OFSO) for the treatment of inflammatory frontal sinus disease.Study Design. Retrospective case series from a single tertiary care facility.Methods. Thirty-four patients who underwent OFSO for chronic frontal sinusitis () and frontal sinus mucocele () comprised our study group. Data reviewed included demographics, history of prior frontal sinus operation(s), imaging, diagnosis, and operative complications.Results. The age range was 19 to 76 years. Seventy percent of patients with chronic frontal sinusitis underwent OFSO as a salvage surgery after previous frontal sinus surgery failures, while 30% underwent OFSO as a primary surgery. For those in whom OFSO was a salvage procedure, the failed surgeries were endoscopic approaches to the frontal sinus (69%), Lynch procedure (12%), and OFSO outside this study period (19%). For patients with frontal sinus mucocele, 72% had OFSO as a first-line surgery. Within the total study population, 15% of patients presented for OFSO with history of prior obliteration, with a range of 3 to 30 years between representations.Conclusions. Osteoplastic frontal sinus obliteration remains a key surgical treatment for chronic inflammatory frontal sinus disease both as a salvage procedure and first-line surgical therapy.

Macroscopic Examination

A 13-year-old female spayed Domestic Shorthair cat presented with a history of right-sided mucopurulent nasal discharge for 18 months. Computed tomography revealed a mass within the right nasal cavity and the right frontal sinus. The animal was euthanized, and a postmortem examination was performed. On macroscopic examination, the right nasal cavity and the right frontal sinus were partially occluded by a soft whitish mass. Microscopically, the mass was composed of well-differentiated plasma cells that were immunopositive for immunoglobulin G and lambda light chains. These findings were consistent with a mature-type sinonasal plasmacytoma. In addition, there was right-sided mucopurulent rhinitis and sinusitis caused by a Pasteurella infection, which probably developed secondary to the sinonasal plasmacytoma. To the authors’ knowledge, this is the first report of a sinonasal plasmacytoma in a cat. The present communication shows that feline sinonasal plasmacytomas should be included in the differential diagnosis for tumors located in the upper respiratory tract of cats.

Sinus Obliteration

OBJECTIVES: Patients who fail endoscopic drainage procedures for chronic frontal sinusitis often require obliteration of the frontal sinus with abdominal fat. The purpose of this study was to evaluate an endoscopic technique for frontal sinus obliteration. STUDY DESIGN AND SETTING: Retrospective case-control. Thirty-five patients underwent frontal sinus obliteration using either an endoscopic (n = 10) or conventional osteoplastic flap (n = 25) technique from 1994 to 2004 at an academic medical center. RESULTS: Patients undergoing endoscopic obliteration had less blood loss (P = 0.006), decreased operative time (P = 0.016), and a shorter hospital stay (P = 0.003) compared to osteoplastic control subjects. All 3 surgical complications occurred in the control group. No patients required additional surgery for frontal sinusitis. CONCLUSIONS: The endoscopic approach to frontal sinus obliteration appears to reduce patient morbidity and should be considered in the surgical management of advanced frontal sinus disease. SIGNIFICANCE: This is the first report of a minimally-invasive technique for frontal sinus obliteration.

Background: The involvement of frontal cells in the frontal sinus disease pathology remains an understudied area. There are very few reports on the prevalence of frontal recess cells in India. In this context the present study was designed to determine the frequency of occurrence of Kuhn frontal cells and to determine whether the size of the frontal isthmus or the presence of frontal cells is related to the presence of frontal sinus disease.Methods: This study included 80 patients who presented with signs and symptoms of chronic rhino-sinusitis after satisfying the inclusion criteria to the Department of ENT in a tertiary care centre (Mahatma Gandhi Medical College and Research Institute) in Pondicherry from January 2017 to April 2018. The patients were subjected to detailed clinical history, basic preoperative blood investigations, diagnostic nasal endoscopy and High Resolution Computed Tomography of nose and para-nasal sinuses after which the diagnosis was established.Results: Out of the 80 study participants subjected to our study the number of individuals who had frontal sinusitis was 50%. The association between frontal sinusitis and Kuhn cells was insignificant. The mean value of anteroposterior diameter of the naso-frontal isthmus in case of patients with and without frontal sinusitis was 0.705-0.735. In case of transverse diameter it was 0.725-0.720 and in case of the area of the frontal isthmus it was 30.86-31.12 which had a p value of 0.49Conclusions: Therefore in our study we concluded that there is no significant relation for any particular frontal recess cell or the size of the nasofrontal isthmus for being the sole cause for chronic frontal sinusitis.

Case summaryA 5-month-old cat was evaluated for a 3 week history of cough, nasal discharge, decreased appetite and weight loss. Musculoskeletal examination was normal and serum creatine kinase (CK) activity was within the reference interval. The cat was treated during the next 10 months for chronic, persistent pneumonia. Weakness then became apparent, the cat developed dysphagia and was euthanized. Post-mortem evaluation revealed chronic aspiration pneumonia and muscular dystrophy associated with beta (β)-sarcoglycan deficiency.Relevance and novel informationThis is the first report of a cat with muscular dystrophy presenting for chronic pneumonia without obvious megaesophagus, dysphagia or prominent neuromuscular signs until late in the course of the disease. The absence of gait abnormalities, marked muscle atrophy or hypertrophy and normal serum CK activity delayed the diagnosis in this cat with β-sarcoglycan deficiency.
