Conditions I Treat:

Benign Lesions: oral cavity (mouth), pharynx (throat), & larynx (voice box)
There are many types of “spots” and lesions that can develop on the mucosa (lining) within the oral cavity, pharynx and larynx. It can often be difficult to distinguish between whether a lesion is benign or malignant. Biopsies are sometimes needed to help make this distinction. If benign, lesions can sometimes be observed (left untreated) or removed surgically if they are causing problems with functions such as eating, speaking, swallowing or breathing.
Oral Cavity Cancer

Cancers can develop in all areas of the mouth, including the on and under tongue, on the lips (inside and outside), inside of the cheeks (buccal), on the gums (gingival) and on the palate. These can affect speaking, chewing, and swallowing and become very painful if left untreated. In many cases, surgery is the best first option for treatment.

Oropharyngeal Cancer

Cancers can develop in an area of the mouth/throat called the oropharynx that includes the tonsils, soft palate and base of tongue. Depending on the size and location, cancers of this region may be treated with up-front surgery or radiation (with or without chemotherapy). If the patient and I decide that surgery is the best treatment option, this is most often performed with transoral robotic surgery (through the mouth).

Laryngeal Cancer

Cancers can develop on different parts of the larynx (voice box) and may affect speaking, breathing and swallowing if left untreated. Depending on the size and location, cancers of this region may be treated with up-front surgery or radiation (with or without chemotherapy).

Salivary Gland Tumors

Benign and malignant tumors can develop in the major (parotid, submandibular and sublingual) and minor salivary glands of the neck and mouth. Surgery is often the recommended up-front treatment for malignant salivary tumors.

Neck Masses & Enlarged Lymph Nodes

Masses or “lumps” in the neck can develop for several reasons. They can be benign, but also may represent the first sign of a head or neck cancer that has not been diagnosed. It is important to thoroughly evaluate any neck mass that has been present for more than 2 weeks without a recent history of infection.

Thyroid & Parathyroid Lesions (benign or malignant)

Many types of lesions (both benign and malignant) can develop within the thyroid and parathyroid glands. These are often discovered by primary care providers or endocrinologists and are referred to otolaryngologists for treatment. In certain cases, surgery is recommended as a primary treatment method after thorough evaluation.

Skin Cancers of the Head & Neck

Multiple types of skin cancer are common in the head and neck region due to this area’s amount of sun exposure over a lifetime. Most skin cancers are treated with surgery as the first-line of treatment. I offer surgery to remove skin cancers of the head and neck, taking care to preserve function and cosmesis to the extent possible. I also perform reconstructive surgery of the areas from where the skin cancer was removed if this is necessary.

Microvascular Free Flap Reconstruction

In some cases of head and neck cancer, surgical removal of a tumor leaves a defect that requires reconstruction. Options for reconstructing these areas include transferring tissue from the arm, leg, or shoulder/back to restore as much speaking and swallowing function as possible.

My Practice:

I specialize in treating patients with benign and malignant (cancerous) lesions and tumors of the head and neck. These encompass the mouth (oral cavity), throat (pharynx), voice box (larynx), salivary glands, neck, face, and thyroid/parathyroid glands.

For patients with head and neck cancer:
Cancers of this region of the body can affect many of the functions that affect our quality of life including speaking and swallowing. For these and other reasons, receiving a diagnosis of a head and neck cancer can be very distressing to patients and their families. It is important for these patients to have a provider they can trust in these difficult situations.

I am committed to using a team-based approach when treating my patients, meaning I routinely collaborate with my colleagues in medical oncology, radiation oncology, speech and swallow therapy, nutrition, and others to ensure that all parties (including my patients) agree on a treatment plan. I offer comprehensive and state-of-the art surgical options for head and neck cancer when surgery is part of the recommended treatment plan. I also perform reconstructive surgery of the head and neck in cases where removal of a tumor requires that the area be reconstructed.

I believe in not only using a team of providers to treat head and neck cancer, but also using a patient-family-physician team to always keep patient concerns at the forefront. I consider it a true privilege to be involved in the care of patients with head and neck cancer.

I am originally from Hawaii, but have called Tennessee home for much of my life. I love it here! Outside of work, I enjoy hiking, traveling and participating in global health and education outreach programs.

How To Stop Snoring: UTHSC ENT’s New Sleep Apnea Procedure

How To Stop Snoring - UTHSC ENT

What is sleep apnea?

Obstructive sleep apnea (OSA) is a common disorder whose symptoms include loud snoring, daytime sleepiness, impaired quality of life, increased risk of heart disease, and even car accidents. It’s estimated that 22 million Americans suffer from sleep apnea, with 80% of cases going undiagnosed. It is likely that you or someone in your household wants to know how to stop snoring!

What causes sleep apnea?

Many patients with OSA have upper airway muscles that become too relaxed during sleep, therefore failing to keep the airway open. Repeated closure of the airway during sleep causes a decrease in blood oxygen that can lead to high blood pressure, heart arrhythmia, daytime sleepiness, and memory problems.

Simply put: these patients’ airway muscles close more than they should during sleep.

How to fix sleep apnea and snoring

For decades, doctors have researched the idea of stimulating the upper airway muscles to stay open during sleep. But the technology to perform this hasn’t been developed–until now!

The Inspire Upper Airway Stimulation (UAS) System (Inspire Medical Systems, Minneapolis, MN, USA) is a small pacemaker device inserted under the skin of the chest that has an electrode that connects to the hypoglossal nerve which stimulates the major dilating muscles of the upper airway. The patient has a hand-held remote control that is used to activate the device prior to sleep.

Does the UAS System work?

Yes! A 2014 study observed a 68% reduction in sleep apnea severity with a mean decrease in the apnea-hypopnea index (AHI) from 29 to 9; an 85% reduction in bothersome snoring; and an excellent safety profile.

More good news: at 48-months of follow-up, implanted patients showed ongoing significant improvement in daytime sleepiness, sleep-related quality of life, and snoring reduction with 81% of patients using the device nightly as their primary form of OSA therapy.

Is it right for me?

The ideal candidate for UAS are patients with moderate to severe sleep apnea (AHI 20-65) who have tried and failed CPAP and who are not overly obese.

In general, Medicare has covered the device, and a growing number of private insurers have approved the device after a case by case review.
