Abstract
INTRODUCTION First case of radiation-induced parotid leiomyosarcoma. ANATOMO-CLINICAL OBSERVATION A 50-year-old woman with a history of cervical irradiation for Hodgkin's lymphoma presented with a right parotid tumefaction. Examination noted a deep adherent pretragal mass with peripheral facial palsy. A total parotidectomy with intra-operative examination and cervical curage was performed. Histopathological analysis concluded to a grade 3 parotid leiomyosarcoma according to the National Federation of Cancer Centers. Adjuvant radiotherapy was performed. After 24 months of follow-up, the patient presented bone and liver metastases without local recurrence. DISCUSSION This is the first case of radiation-induced leiomyosarcoma and the 12th case of parotid leiomyosarcoma described in the literature. The management associates surgery with adjuvant radiotherapy. Follow-up is by clinical examination, parotid MRI, and annual thoracoabdominal CT scan to search for metastases. Recurrences occur during the first year in 40 to 64% of cases, and distant metastases in 40 to 60% of cases. The 5-year survival rate is between 10 and 30%.

Abstract
OBJECTIVE Assess the feasibility of cochlear implantation as day-surgery in children and identify variables influencing admission, readmission, and unplanned postoperative consultation. METHODS This retrospective observational monocentric study was conducted according to the STROBE recommendations. Between January 2017 and July 2022, all medical records of children who underwent cochlear implantation were analyzed. Eligible children were admitted for the first time to the pediatric day-surgery unit. Exclusion criteria were children planned for inpatient procedure, bilateralization or explantation-reimplantation. Sex assigned at birth, analgesic medication, anesthesia and complications were related to categorical variables. Age, duration of anesthesia, length of stay and ASA score were related to continuous variables. RESULTS We included 66 children from a total of 106. Mean age was 53 months [SD: 46 months, range 8-184 months]. Successful day-surgery management was observed in 86% of cases. In 14% of cases, children were admitted to the pediatric ENT unit for the following reasons: late awakening in 6%, non-controlled pain in 4.5%, postoperative nausea and vomiting in 3.5% of cases. Univariate analysis did not observe any factor promoting success of day-surgery regarding anesthetic agents. Age was not statistically significant as a factor of ambulatory failure. Time spent in the operating room was not a determining factor (p = 0.559). None of the children were rehospitalized. Early unplanned consultations were observed in 3% of cases for vertex edema in 1 case and uncomplicated otorrhea in 1 case. CONCLUSION This study adds to the knowledge on pediatric cochlear implantation and suggests that this procedure is suitable for day-surgery at any age.

Abstract
Treating pathologies of the inner ear is a major challenge. To date, a wide range of procedures exists for administering therapeutic agents to the inner ear, with varying degrees of success. The key is to deliver therapeutics in a way that is minimally invasive, effective, long-lasting, and without adverse effects on vestibular and cochlear function. Microbubble-assisted ultrasound ("sonoporation") is a promising new modality that can be adapted to the inner ear. Combining ultrasound technology with microbubbles in the middle ear can increase the permeability of the round window, enabling therapeutic agents to be delivered safely and effectively to the inner ear in a targeted manner. As such, sonoporation is a promising new approach to treat hearing loss and vertigo. This review summarizes all studies on the delivery of therapeutic molecules to the inner ear using sonoporation.
