About

About Shawn Allen, MD

Dr. Allen was born in Houston, Texas.  At the age of 6 years his family moved to Tennessee, where he developed an interest in science and medicine while learning piano and enjoying the outdoors.  He met his wife in medical school at the University of Tennessee.  After completing his medical education and residency in Tennessee and fellowship training in Rhinology (sinus and skull base surgery) at the University of Miami, Dr. Allen moved his family to the Houston area to develop an Otolaryngology (ENT) practice specializing in the care of sinus and nasal breathing disorders.  He is both a Fellowship-certified sinus expert and a diplomate of the American Board of Otolaryngology.

Dr. Allen is an active member of the American Rhinologic Society (ARS).  He has authored multiple scientific publications and book chapters, and continues to lecture for academic departments and at international Rhinology and Endoscopic Skull Base Surgery courses.

In 2021 Dr. Allen joined Dr. Ben Cilento at his practice Texas Sinus & Snoring. He is focused on a commitment to comprehensive and compassionate care.

Outside of work, Dr. Allen enjoys spending time with his wife and children, playing the piano, and staying active.  He has strong family ties to Houston and surrounding areas in Texas, and is excited to call The Woodlands home and become an integral part of the local medical community.

What is A Rhinologist?

A Rhinologist is an ENT subspecialist that focuses on the treatment of conditions within the nasal passages and sinuses. As a Rhinologist and sinus surgeon, Dr. Allen has fellowship training and additional expertise compared to a non-fellowship trained ENT in treating the following conditions:

SINUSITIS

Patients with recurring acute sinus infections and chronic sinusitis have bothersome symptoms such as nasal congestion, sinus pressure and pain, nasal drainage, smell dysfunction, and much more. Everyone is different, and this is particularly applicable in sinusitis. Expertise in the many treatment options available ensures that patients get the right treatment the first time as well as ongoing care to manage underlying conditions such as allergies and immune system problems. Having trained at one of the busiest sinus and skull base centers in the country, Dr. Allen is able to handle even the toughest cases of complex or revision sinus disease.

NASAL OBSTRUCTION

Impaired nasal breathing impacts everything from quality of sleep to exercise tolerance. Causes range from enlarged turbinates (often due to allergies or overuse of nasal decongestant sprays), deviated nasal septum, nasal polyps, or even tumors within the nasal cavities or sinuses. Diagnosing the underlying cause involves imaging (often a quick in-office CT of the sinuses and nasal cavities) and in certain cases nasal endoscopy to investigate the exact cause of obstruction. Dr. Allen has expertise in treating nasal obstruction, including septoplasty, turbinoplasty, polyp removal, and even sinus and nasal tumor removal.

OTHER ASPECTS OF RHINOLOGY

While sinus and nasal obstruction complaints comprise the vast majority of patients in a Rhinology practice, there are many less common conditions that Dr. Allen is well-trained in managing. These include:

  1. Epiphora (chronic eye tearing) caused by nasolacrimal duct obstruction
  2. Epistaxis (nosebleeds)
  3. Anosmia (smell loss) or reduced sense of smell
  4. Chronic nasal drainage or postnasal drip
  5. Cerebrospinal fluid (CSF) leaks into the nose and sinuses
  6. Tumors of the nasal cavities and sinuses
  7. Intracranial pathology in collaboration with Neurosurgery (ex. pituitary neoplasms)
