Plain-English summary
Five dogs who had previously undergone throat surgery were anesthetized for various procedures, and during intubation, one dog was found to have a laryngeal web, which is a complication from their earlier surgery. While four of the dogs showed no unusual symptoms, one dog coughed after drinking, which started after the surgery. To address the air leak caused by the laryngeal web, a smaller endotracheal tube was used, and the cuff was adjusted to seal the leak effectively. All dogs had successful intubation without any complications during their procedures.

Abstract
CASE DESCRIPTION: 5 dogs with a history of ventriculocordectomy were anesthetized with isoflurane for ovariohysterectomy, dental prophylaxis, or intracapsular lens extraction. CLINICAL FINDINGS: No remarkable, abnormal clinical signs such as exercise intolerance, respiratory distress, or stridor were found in 4 dogs. However, 1 dog had cough after drinking, which had started after the ventriculocordectomy. During intubation, laryngeal web, suspected to be a complication of ventriculocordectomy, was accidentally discovered. TREATMENT AND OUTCOME: Laryngeal web was observed during intubation, necessitating the use of a smaller-diameter endotracheal tube (ETT) for intubation. However, the smaller cuff volume of the smaller ETT did not prevent the air leak. Therefore, the ETT with the inflated cuff was pulled cranially until the narrowed laryngeal lumen was plugged with the cuff behind the vocal cords. The ETT was secured to prevent slippage. No air leakage around the ETT cuff or complications related to the ETT placement were observed in the peri-anesthetic period in any dog. CLINICAL RELEVANCE: Laryngeal web can be found in patients with a history of larynx-related surgeries and may allow only a small-diameter ETT to pass through. The sealing technique used for peri-cuff air leak using a small ETT described here that can pass through a laryngeal web could be useful to seal an air leak around the cuff without complications.
