As a member of a team of healthcare specialists, your oral and maxillofacial surgeon (OMS) plays an important role in the carefully orchestrated, multiple-stage correctional program for cleft lip and palate patients.

The cleft hard palate is generally repaired between the ages of 8 and 12, when the cuspid teeth begin to develop. The procedure involves placement of bone from the hip into the bony defect, and closure of the communication from the nose to the gum tissue in three layers. It may also be performed in teenagers and adults as an individual procedure or combined with corrective jaw surgery.

Dr. Throndson has an extensive experience in treating these cases and he works with an entire pediatric cleft lip and palate team comprised of specialized dentists/orthodontists, pediatricians, pediatric ENT physicians, speech and language pathologists to provide comprehensive care for your child.

Dental implants are the long-term solution for your missing teeth. If properly cared for, dental implants can last a lifetime. The implants are made of titanium and usually take several months to fuse with your jaw bone, in the process known as Osseointegration. Our experts here at UTMB are trained in management of the most complex cases and they are here to help you to get your teeth back.

Oral and Maxillofacial Surgeons (OMSs) are experts in treating and repairing facial injury and trauma, including fractures of the upper and lower jaws and the orbits surrounding the eyes, and facial lacerations. Their knowledge of how jaws come together (dental occlusion) is critical when repairing complex facial fractures. Many of the techniques that are standard in today's hospital emergency rooms were developed by OMSs in combat hospitals during World War II, Korea, Vietnam and today's international conflicts.

Trauma care is provided through UTMB Health Level 1 Trauma Center at Galveston.

Infections within the head and neck, including your jaw bones (mandible and maxilla), may occur as a result of dental infection, exposure to radiation for treatment of a head and neck cancer (osteoradionecrosis-ORN) or as a result of exposure to a bisphosphonate medication (MRONJ). The treatment may range from medical therapy (Antibiotic), simple incision and drainage, and possibly to advanced surgical techniques with immediate jaw reconstruction using microvascular free tissue.

The UTMB faculty are experts in the management of these conditions. We work closely with the infectious disease team at UTMB Health to provide you with the best care tailored to your condition.

The division of Oral and Maxillofacial Surgery at UTMB utilized the latest cutting-edge technologies and advancement in the field of nerve repair and reconstruction. We are able to alleviate pain and restore function that has been lost due to nerve damage and disease.

Dr. Marwan is a fellowship-trained expert specialize in both, nerve surgery following traumatic injury and microsurgical techniques. These techniques treat the nerves, which are the most vital and delicate structures that carry messages from the brain to the rest of the body.

Obstructive sleep apnea is a serious and even life-threatening condition. The risks of undiagnosed OSA include heart attack, stroke, irregular heartbeat, high blood pressure, heart disease and decreased libido. In addition, OSA causes daytime drowsiness that can result in accidents, lost productivity and relationship problems. 

The National Sleep Foundation estimates that 18 million adults have obstructive sleep apnea and it is likely that OSA also affects 2% to 3% of children. Yet, people who have OSA may not be aware they have a problem. If someone close to you has spoken of your loud snoring and has noticed that you often wake up abruptly, gasping for air, you should consult us at UTMB Oral and Maxillofacial Surgery. Our Surgeons are the experts in diagnosis and surgical management of obstructive sleep apnea.

The oral cavity has multiple structures that can be affected by various disease processes. Any alteration in this appearance could be a warning sign for a pathological process with the most serious is oral cancer. Generally speaking, biopsy is considered the gold standard to establish a diagnosis, often able to be performed in the outpatient clinic under local or IV sedation.

Dr. Marwan is an expert in the management of oral/head and neck cancer and benign conditions of the jaws. Also, he provides a compassionate and comprehensive care for all of his patients from diagnosis until treatment and follow up.

Your oral and maxillofacial surgeon (OMS) is the expert for diagnosing and surgically treating cancer of the head, neck and mouth.

The Oral Cancer Foundation estimates that close to 42,000 Americans will be diagnosed with oral or pharyngeal cancer this year. Oral cancer’s mortality is particularly high, not because it is hard to detect or diagnose, but because the cancer is often discovered late in its development.

Don't ignore any suspicious lumps or sores. Should you discover something, make an appointment for a prompt examination. Early treatment may well be the key to complete recovery.

Oral/Head and Neck cancer treatment requires a multidisciplinary approach to care involving surgeons, radiation oncologists, medical oncologists, speech/language pathologists, maxillofacial prosthodontists, nutritionists and rehabilitation therapists.

The Oncology team at UTMB are an experienced team of surgeons with a focus on the surgical management (ablation and reconstruction) of cancers of the head and neck.

Dr. Marwan is trained in all aspects of the surgical management (Ablation and Reconstruction) of Oral/Head & Neck cancer. Also, he is an active member in the Head and Neck Multidisciplinary Tumor Board at UTMB.

Orthognathic surgery, also called corrective jaw surgery, is performed by an oral and maxillofacial surgeon (OMS) to correct a wide range of minor and major skeletal and dental irregularities, including the misalignment of jaws and teeth.

Surgery can improve chewing, speaking and breathing. While the patient's appearance may be dramatically enhanced as a result of the surgery, orthognathic surgery is performed to correct functional problems.

We work very closely with the orthodontist and your general dentist to plan and decide the best surgical procedure to correct your jaw deformity. During your visit, we will show you how your bite will be improved and how you will look after the surgery.

Also, we pride ourselves by using the cutting-edge computer technologies and virtual surgical planning to perform your case with extreme accuracy.

The division of Oral and Maxillofacial Surgery at UTMB offers a comprehensive reconstruction for all cancer related and post traumatic defects for both children and adults.

We proud ourselves by implementing cutting edge and state of art technologies in planning your reconstruction. This will provide you with the most precise reconstruction of the defect.

Microvascular reconstruction is one of the most advanced options in restoring facial form and function following the removal of facial and oral tumors. These techniques are also used to repair defects caused from traumatic injuries. Tissue from the patient’s own body are transplanted into the facial defects to restore function and appearance. These transplants (known as “flaps”) can be in the form of skin, muscle, bone, or any combination. The flap is removed from the body along with blood vessels that supply nourishment to the flap. The blood vessels are reconnected to vessels around the facial defect under a microscope using sutures smaller than a human hair. Once blood flow is re-established, the transplanted tissue remains alive just as it did in its original location. Because the flap is completely freed from another part of the body, this technique is often referred to as “free flap surgery” or “free tissue transfer.” This technique has a 95 percent success rate, which is very favorable compared to other techniques. Please keep in mind that many cases are more appropriately reconstructed with alternative techniques.

While not all patients are candidates to undergo this form of reconstruction, our surgeons also perform many other forms of facial reconstructive surgery. The optimal reconstructive technique is tailored to each patient and chosen based on the patient’s wishes, goals, and available options.

Dr. Marwan is fully trained Oral/Head and Neck microvascular Surgeon and he utilizes the Microvascular surgical techniques to immediately reconstruct the cancer related defects. In addition, He is trained to perform jaw reconstruction using the stem cells and the tissue engineering techniques, without the use of bone graft from other region of the body, if indicated.

The salivary glands are specialized glands that produce saliva that drain into the mouth and throat.

The two most common problems associated with salivary gland disease include obstructive diseases (result of salivary stones) and tumors (can be either benign or malignant)

Patients referred for management of salivary disease will often require advanced imaging techniques such as CT scan, MRI or ultrasound guided imaging with biopsy to help establish a diagnosis.

Dr. Marwan is also trained in minimally invasive technique using the Sialoendoscopy for retrieval of the salivary gland stones without removing the gland itself.

The Hemangiomas in children and vascular malformation in adults are relatively common in the head and neck region. They often occur within the tongue causing symptoms of speech impairment, swelling and swallowing dysfunction. Treatment includes both non-surgical (sclerotherapy) and surgical removal with reconstruction.

Wisdom teeth, or third molars, are the last teeth to appear in your mouth. They usually come in between the ages of 17-25. Wisdom teeth are called impacted when they don’t fully grow, and this happen when there is not enough room in the mouth. Impacted wisdom teeth can damage adjacent teeth and get infected. Also, in some cases tumor or cyst might develop from these teeth, which leads to multiple serious problems. We encourage all of our patients to have their third molars checked by Oral and Maxillofacial Surgeon. The worst thing that you can do is to ignore your wisdom teeth.
