ABSTRACT

The objective of this retrospective study was to report the overall peri-operative complications and short- to long-term outcomes of subtotal ear canal ablation and lateral bulla osteotomy in French bulldogs with otitis media. Medical records from 2018 to 2021 were reviewed for preoperative neurological signs, surgical technique, postoperative complications, and long-term outcomes. Postoperative complications, such as a head tilt, nystagmus, ataxia, facial nerve dysfunction, as well as skin or wound infection, were recorded. Eighteen client-owned dogs (20 ears) were included in the study. Postoperative complications were observed in 5/18 dogs (6/20 ears) with 2 of them being considered major complications. Referring veterinarians and owner telephone follow-up (mean: 33 mo, range: 17 to 56 mo) were obtained for all patients. Total recovery was reported in 9/18 dogs (11/20 ears) with a postoperative improvement of the vestibular signs and facial nerve paresis within 8 wk. All dogs maintained the pinnas' natural, erect morphology, and movement.


L'objectif de cette étude rétrospective était de rapporter les complications peropératoires globales et les résultats à court et à long terme de l'ablation subtotale du conduit auditif et de l'ostéotomie de la bulle latérale chez les bouledogues français atteints d'otite moyenne. Les dossiers médicaux de 2018 à 2021 ont été examinés pour les signes neurologiques préopératoires, la technique chirurgicale, les complications postopératoires et les résultats à long terme. Les complications postopératoires, telles qu'une inclinaison de la tête, un nystagmus, une ataxie, un dysfonctionnement du nerf facial, ainsi qu'une infection de la peau ou des plaies, ont été enregistrées. Dix-huit chiens de propriétaires (20 oreilles) ont été inclus dans l'étude. Des complications postopératoires ont été observées chez 5/18 chiens (6/20 oreilles) dont 2 ont été considérées comme des complications majeures. Les vétérinaires référents et le suivi téléphonique des propriétaires (moyenne : 33 mois, intervalle : 17 à 56 mois) ont été obtenus pour tous les patients. Une récupération totale a été rapportée chez 9/18 chiens (11/20 oreilles) avec une amélioration postopératoire des signes vestibulaires et une parésie du nerf facial en 8 semaines. Tous les chiens ont conservé la morphologie et le mouvement naturels et dressés des pinnas.(Traduit par Docteur Serge Messier).

ABSTRACT

BACKGROUND: This is a pilot study to evaluate the effects of fentanyl on intraocular pressure (IOP) and pupil size (PS) in dogs premedicated with medetomidine and methadone. METHODS: Sixteen dogs with a median (first quartile-third quartile) age of 3.5 (1.25-6) years and a mean (sd) weight of 18.6 (9.2) kg were included. Baseline readings of IOP and PS were recorded before all dogs were premedicated intramuscularly with medetomidine (10 µg/kg) and methadone (0.5 mg/kg). Both measurements were repeated 15 and 30 minutes later. Following this, the dogs were randomly assigned into two groups. The fentanyl group received intravenous fentanyl (10 µg/kg), while the control group received the same volume of saline solution intravenously. IOP and PS measurements were measured and recorded in both groups at one, five and ten minutes after intravenous injection. Data were analysed with one-way and two-way repeated-measures analysis of variance or their non-parametric equivalents. RESULTS: PS was significantly decreased 15 and 30 minutes following intramuscular premedication and IOP was significantly increased in the fentanyl group at all time points following intravenous administration. CONCLUSIONS: Medetomidine, methadone and fentanyl combinations are not recommended for use in patients where an increase in IOP or decrease in PS is undesirable.
