Abstract
OBJECTIVES Partial laryngectomy is an organ-sparing surgical procedure for the removal of laryngeal masses which has not been described in cats. The aim of this study was to report on the surgical procedure and the short- and long-term clinical outcomes of cats that underwent partial laryngectomy. METHODS Medical records were retrospectively collected over a 4-year period in two institutions. The following data were retrieved: signalment, history, clinical signs, diagnostic test results, surgical procedure, postoperative management, complications and outcome. RESULTS Six cats underwent partial laryngectomy. The most common clinical signs in cats with laryngeal masses were stridor (n = 4) and dyspnoea (n = 4). In all cats, a full-thickness portion of one or several laryngeal cartilages was resected, including thyroid cartilage alone (n = 2), thyroid cartilage and arytenoid (n = 2), and arytenoid cartilage and epiglottis (n = 2). The resected laryngeal masses were reported to be lymphoma (n = 3), carcinoma (n = 1), laryngeal cyst (n = 1) and inflammatory laryngeal disease (n = 1). All cats survived the surgical intervention of partial laryngectomy. Four cats showed varying degrees of respiratory distress in the short-term postoperative period. A temporary tracheostomy tube was placed in two cats. No other postoperative complications were noted in the short- or long-term. Four cats were still alive at the time of writing. These cats survived at least 252 days. CONCLUSIONS AND RELEVANCE In a small number of cases, our results show that successful long-term outcomes after partial laryngectomy are achievable, with longer survival times than previously reported. Therefore, partial laryngectomy should be considered as a viable treatment option in cats with laryngeal masses.

Abstract
Case summary This report describes a 10-year-old female spayed Russian Blue cat presented with a 5 month history of respiratory difficulty. Thoracic radiographs were suggestive of a central airway obstruction. Bronchoscopy revealed a broad-base mass in the region of the carina. Bronchoscopic debulking was performed using a urinary catheter. Histopathology confirmed the presence of a tracheobronchial carcinoma. Survival from diagnosis was 16 months (480 days), over which time the cat underwent three endoscopic debulking procedures in combination with doxorubicin chemotherapy. Relevance and novel information To our knowledge, this is the first report of a tracheobronchial carcinoma in a cat treated by endoscopic debulking with a urinary catheter and adjuvant chemotherapy with long-term survival time. A review of interventional bronchoscopy performed in humans and in veterinary medicine is described.

Abstract
A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and
a 3-month history of voice change. Laryngeal endoscopy revealed circumferential oedema
around the arytenoid cartilages and hypersecretion of saliva. Histopathological
examination of the mass around the left ear canal was considered the primary lesion that
originated from cutaneous apocrine adenocarcinoma or parotid gland adenocarcinoma, and it
metastasized to the larynx, lung and medial retropharyngeal lymph nodes. This report
provides new insights into feline laryngeal diseases which could result in laryngeal
metastasis with slight mucosal irregularity alone and without obvious radiographic
abnormalities. Therefore, histopathological examination should be performed when a cat
presents clinical signs such as stridor, dysphonia or voice change without any
mass-forming laryngeal lesion.

Abstract
Three cats showing chronic, intermittent respiratory distress associated with increased noise on inspiration were examined. Head, neck and thoracic radiographs were unremarkable and laboratory findings were within normal ranges. In all three cats direct laryngoscopy revealed bilateral redundant arytenoid mucosa, which collapsed into the supraglottic and glottis airways during inspiration. Temporary tracheostomy and endoscopic diode laser excision of the excessive mucosa resolved symptoms in all three cats. Redundant arytenoid mucosa is a rare condition that may cause signs similar to laryngeal paralysis or laryngeal mass in cats. According to our results, diode laser surgery in association with temporary tracheostomy appears an appropriate mode of therapy.

Abstract
The aim of this retrospective study was to review the medical records of cats referred to the University of Bristol for investigation of laryngeal disease (n=35). Cases were categorised into one of four groups: cats with laryngeal paralysis (LP, n=14), laryngeal neoplasia (n=10), laryngeal inflammation (n=6), or miscellaneous laryngeal diseases (n=5). Laryngoscopy and echolaryngography were useful diagnostic techniques but histology was required for diagnosis of diseases other than LP. Two cats with lymphoma received chemotherapy achieving survival times of 60 and 1440 days. Four cats with LP were treated surgically, with a median survival time of 300 days (range 10–360 days) and six were treated conservatively with a median survival time of 780 days (range 300–2520 days). Three cats with inflammatory disease were treated medically and one by excision of the lesion. Two cats achieved survival times of 120 and 2800 days. Cats with LP, laryngeal lymphoma or laryngitis had excellent long-term survival following appropriate treatment.

Abstract
Tracheostomies can be used to provide a patent airway in animals with upper airway obstruction but have been reported to be more difficult to manage in cats than in other animals. The purpose of this study is to retrospectively describe the indications, complications and outcome of cats undergoing tracheostomy. Twenty-three cats underwent tracheostomy for laryngeal mass (n=13), trauma (n=5) and upper airway swelling (n=5). Major and minor complications were recorded in 10 and 17 cats, respectively. Seventeen cats were discharged to home, four cats were euthanased and two cats died in hospital. Complications with stoma healing were reported in one cat. Of seven cats discharged with a permanent tracheostomy, one cat is alive and six cats survived at home for between 2 and 281 days. Although complications are common, temporary tracheostomies can be beneficial for conditions in which the underlying cause can be treated. Despite risk of occlusion, permanent tracheostomies can be effective palliative procedures for cats with severe upper airway disease.

Abstract
Medical records of 27 cats with masses of the larynx and trachea were examined. Six cats had inflammatory masses, and 21 cats had neoplastic lesions. A definitive diagnosis was reached in 22 cats with a single biopsy. The median age of the cats was 12.0 years (range 6 to 20 years). Dyspnea was the most common clinical sign. Accurate diagnoses were best obtained through direct laryngeal or tracheal examination combined with histological examination of tissue biopsies. Kaplan-Meier survival data for all inflammatory and neoplastic lesions showed a median survival of 5 days, with 7.4% of cats alive at 1 year.
