Faculty members in Pediatric Otolaryngology are actively involved in a wide range of research activities. Dr. Tara Rosenberg leads our research activity related to the diagnosis and treatment of vascular anomalies. Recent projects and publications have addressed laser treatment for vascular anomalies of the head and neck, Transforming Growth Factor ß-1 and related receptors expression in arteriovenous malformations, primary surgical excision of venous malformations of the head and neck, role of percutaneous direct puncture sclerotherapy with bleomycin in the multimodality treatment of arteriovenous malformations of the head and neck, and other topics. Dr. Julina Ongkasuwan leads our research activity related to the diagnosis and treatment of pediatric voice disorders. Current projects and recent publications have addressed innovative ways to identify laryngeal pathology such as laryngeal ultrasound and audiometers. Dr. Deepak Mehta leads our research activity related to the diagnosis and treatment of congenital and acquired airway anomalies. Together with Drs. Raynor, Cañadas, and Ashe-Lambert, current projects and recent publications have addressed outcomes of swallowing in laryngomalacia and laryngeal cleft and the role of multidisciplinary care of tracheostomized patients and their outcomes. Ongoing research includes economical impact and outcomes of standardization of tracheostomy care, perioperative management of single stage laryngotracheal reconstruction, management of tracheostomy in patients with cardiac anomalies. The other projects include role of bioengineered stents in the management of subglottic stenosis in a pig model and 4-D CT imaging in the diagnosis and management of complex airway patients. Also within this group, Dr. Raynor and Dr. Arjmand are leading the Texas Children’s Care Process Team for improvement in the management of children who have a tracheostomy. Dr. Robert Williamson leads our research activity related to the diagnosis and treatment of pediatric sensorineural hearing impairment, including cochlear implant surgery and the surgical correction of microtia and atresia. Together with Drs. Sitton, Vilela and Liu, current projects and recent publications have addressed novel use of cochlear implantation in genetic conditions, the utility of CT imaging in cochlear reimplantation, collaborative efforts to characterize clinical and epidemiologic features of hearing loss in pediatric renal failure/dialysis patients, and MR imaging for posterior fossa lesions in pediatric patients with sensorineural hearing loss. Dr. Williamson is investigating outcomes in cochlear implant recipients for whom the native language spoken in the home is different from that spoken by the members of the CI team. Drs. Chelius and Sitton lead our research activity related to solid tumors of the head and neck, including thyroid tumors. Current projects and recent publications have addressed the multidisciplinary care of extremely young patients with head and neck cancer, the care of patients with rare head and neck masses, and the otolaryngology care of patients with complications of cancer care such as hearing loss and sinusitis. Dr. Mussso leads our research activity in the area of otolaryngologic disorders in children with Down syndrome, including sleep disorders. Current projects and recent publications have addressed magnetic resonance imaging in children with sleep apnea supported by Texas Children’s Hospital Department of Surgery Seed Grant. Dr. Chandy leads our research activities in the area of airway management in fetal surgery patients and complex rhinology. Current projects and recent publications have addressed airway management of head and neck teratomas and evaluating the prevalence and extent of obstructive sleep apnea in the cleft lip and palate population.
