Meet Dr.Dani Gonzalez at Austin Pediatric Surgery! Learn more about how we're serving Central Texas. Dani Gonzalez, MD, FACS Meet Dr. Gonzalez "I am drawn to pediatric surgery by the breadth of cases that I can see in a single day. I enjoy both the variety in types of cases and the types of patients ranging from acute outpatient conditions to long standing conditions requiring long term follow-up to prenatal consults for expecting parents. Over the course of my career, I have developed an affinity for minimally invasive surgical techniques, including laparoscopy and thoracoscopy." My Journey to Pediatric Surgery "My passion for healthcare stemmed from seeing my grandparents have trouble navigating through complex medical systems as non-English speakers. I recall the difficulty they had understanding medical providers, which led to a poor understanding of their own healthcare needs. As a result, I developed a passion for ensuring that patients and their caregivers are armed with as much knowledge as possible in order to take an active role in their health. In addition to that, I really enjoy getting to know patients and their caregivers to fully understand what their needs are as patients. As a Pediatric Surgeon, I am humbled every day by the opportunity to care for babies and children." My Clinical Focus Dr. Gonzalez specializes in a wide range of pediatric surgical care, from outpatient procedures to long-term management of complex conditions and prenatal consultations.

Expert care for thyroglossal duct cysts, branchial cleft cysts, thyroid conditions, and tongue-tie surgery. Compassionate pediatric surgeons in Austin. Head & Neck Surgery THYROGLOSSAL DUCT CYST BRANCHIAL CLEFT CYST THYROID DISEASE / SURGERY TONGUE TIE SURGERY Our team of pediatric surgeons specializes in diagnosing and treating various head and neck conditions. Whether congenital or acquired, we’re dedicated to providing expert care tailored to your child’s unique needs. Thyroglossal Duct Cyst What is it? A thyroglossal duct cyst is the most common neck condition that your child can be born with. It can look like a painless lump in the upper neck, which may move when swallowing or sticking out the tongue. They can become infected, which is why we recommend removing them when they are diagnosed. Evaluation and Diagnosis Diagnosis is usually made through a physical exam. An ultrasound can be used to confirm the cyst and ensure the thyroid gland is normal. Treatment Surgery (the Sistrunk procedure) removes the cyst and its associated duct under general anesthesia. Infections must be treated first. Children may go home the same day as the procedure or stay overnight. Recurrence is rare, but possible. Follow-Up Care Post-surgery instructions will include wound care and activity guidelines. Pain is managed with over the counter medications. Follow-up appointments occur 2-4 weeks after surgery. When to Call the Doctor Contact your doctor if signs of infection (redness, swelling, or fever), neck swelling, or other concerns arise. Branchial Cleft Cyst What is it? This neck condition your child is born with is from abnormal development of the different glands and structures on the side of the neck. Most commonly, it appears as a painless swelling or a small skin opening that may intermittently drain fluid. Evaluation and Diagnosis Diagnosis is based on a physical exam and ultrasound. CT or MRI may be needed for unclear cases. Treatment Surgery removes the cyst or sinus under general anesthesia, with infections treated first. The procedure lasts 1-2 hours, and your child may go home the same day or stay overnight. Recurrence risk is low. Follow-Up Care Wound care and pain management instructions will be provided, and a follow-up visit is scheduled 2-4 weeks post-surgery. When to Call the Doctor Contact your doctor if signs of infection (redness, swelling, or fever), neck swelling, or other concerns arise. Thyroid Disease What is it? The thyroid gland regulates metabolism and other body functions. Conditions include thyroid nodules, hyperthyroidism, and hypothyroidism, which may present as lumps, fatigue, or mood changes. Evaluation and Diagnosis Diagnosis involves a physical exam, blood tests, and ultrasounds. A biopsy may be recommended for thyroid nodules. Treatment Certain thyroid conditions require surgery to remove a portion of the thyroid or the entire thyroid. Our group has a specialty program dedicated to specifically taking care of children with surgical thyroid conditions, led by Dr. Jeffrey Horwitz . Follow-Up Care Post-surgery care includes monitoring hormone levels, wound care, and medication for those with full thyroid removal. A follow-up visit occurs 1-2 weeks post-surgery. When to Call the Doctor Contact your doctor if signs of infection (redness, swelling, or fever), neck swelling, or other concerns arise. Thyroid Surgery Program Although thyroid disease is less common in children compared to adults, occasionally surgical issues arise. Most commonly this is for an overactive thyroid gland (hyperthyroidism) or a concerning thyroid nodule. Treating pediatric thyroid disease requires a multidisciplinary approach. As the lead surgeon of our Thyroid Surgery Program, Dr. Jeffrey Horwitz works closely with our partners in pediatric endocrinology, pediatric radiology and pediatric pathology. In addition, because recent studies have suggested that high volume thyroid surgeons (performing > 30 cases/year) have improved outcomes, Dr. Horwitz has partnered with Dr. Teresa Kroeker, one of the region’s leading adult thyroid surgeons. This collaboration between pediatric surgeons and a high-volume adult thyroid surgeon optimizes the care of children with surgical thyroid disease conferring the benefits of both a high volume thyroid surgeon and high volume pediatric surgical care. Tongue-Tie Surgery What is it? Tongue-tie (ankyloglossia) occurs when a tissue band restricts tongue movement. It may interfere with feeding or speech. Treatment Pediatric tongue-tie surgery releases the tongue and is performed under general or local anesthesia, depending on age. Recovery involves minimal discomfort managed with over the counter medication.

Offering minimally invasive solutions for appendicitis, bowel obstructions, reflux, and other pediatric gastrointestinal conditions. Gastrointestinal Surgery APPENDICITIS MECKEL’S DIVERTICULUM ESOPHAGEAL DISORDERS INTESTINAL (BOWEL) OBSTRUCTION GASTROSTOMY PLACEMENT OTHER ABDOMINAL SURGERY Our team of pediatric surgeons specializes in diagnosing and treating gastrointestinal conditions in children. From common issues like appendicitis to complex conditions like bowel obstructions, we provide expert care designed to help your child recover quickly and comfortably. Appendicitis What is it? Appendicitis occurs when the appendix becomes blocked and inflamed, often requiring surgery. It is one of the most common reasons otherwise healthy children need surgery. Signs and Symptoms Abdominal pain, typically on the right side Nausea, vomiting, fever, and loss of appetite Diagnosis Diagnosis is based on symptoms, lab tests, and ultrasound. Additional imaging such as CT scans or MRI may be needed to make the diagnosis. Treatment Most cases require laparoscopic surgery to remove the appendix. In certain cases, antibiotics alone may be considered. Follow-Up Care Recovery depends on the surgery performed. Contact your surgeon for any concerns. Meckel’s Diverticulum What is it? This congenital condition involves an outpouching in the small intestine, sometimes can cause bleeding. Signs and Symptoms Abdominal pain, nausea, vomiting Bleeding or blockages Diagnosis Tests like a Meckel’s scan or CT scan can be helpful to confirm the condition. Treatment Surgical removal via laparoscopic or open surgery is performed for symptomatic cases. Intestinal (Bowel) Obstruction What is it? An obstruction prevents food or stool from passing through the intestine, caused by scar tissue, twisting, or congenital conditions. Signs and Symptoms Abdominal pain, vomiting, bloating Inability to pass gas Diagnosis Imaging tests like X-rays or CT scans confirm the blockage. Treatment Initial care includes bowel rest, IV fluids, decompression of the intestine with a tube in the nose and possibly surgery for severe cases. Gastrostomy Placement What is a Gastrostomy? A gastrostomy is when the stomach is connected to the abdominal wall using sutures to form a tract between the stomach and the skin. What is a G-button? A G-button (also called a gastrostomy button, gastrostomy tube, or G-tube) is a small tube that is surgically placed into the stomach through a small cut in the abdomen. This is a long-term and more sturdy way to receive medications and nutrition when oral feeding is not sufficient or deemed unsafe. Device Management You will learn to give feeds and medications through the G-button/G-tube. You will also learn how to clean the area once or twice a day and connect/disconnect the tubing. G-button changes are done as needed and at minimum every 6 months routinely. This can be done in the clinic or at home and is not a painful procedure. Nutrition is managed by the pediatrician, dietitian, or gastroenterology. The device itself is managed by your surgical team or the g-tube nurse practitioner. How Long is the G-button in Place? The G-button or G-tube can remain for as long as your child needs it based on their medical condition. If all nutrition and medications are sufficiently taken orally, your primary physicians will give clearance to remove the G-button. The site will either close spontaneously or will require surgical closure. Esophageal Disorders We specialize in the full spectrum of pediatric esophageal disorders (such as achalasia, congenital esophageal stenosis, esophageal atresia with tracheoesophageal fistula, duplication cysts, reflux) in infants and children and work collaboratively with other specialists to provide a tailored multidisciplinary treatment plan for your child's specific disorder. Other Abdominal Surgery Austin Pediatric Surgery provides expert care for various abdominal conditions requiring surgical intervention. Beyond common procedures like appendectomies and treatments for inflammatory bowel disease, our skilled team addresses complex conditions such as spleen disorders, adhesion-related obstructions and rare gallbladder anomalies. With advanced training in pediatric and minimally invasive techniques, the surgeons ensure precise, compassionate care tailored to each child’s needs. Every procedure is approached with the goal of achieving the best outcomes while prioritizing comfort and safety for young patients and their families. Please contact us to learn more.
