Functional Approach to ENT - Sleep and Breathing: Adults and Pediatrics


Snoring – A loud, hoarse or harsh breathing sound that comes from loose, relaxed tissues that vibrate while breathing during sleep.


Upper Airway Resistance Syndrome - When snoring and resistance through the airway is significant enough to disrupt the quality of sleep. Sleep quality is generally disrupted to the point of causing clinical consequences such as difficulty initiating or maintaining sleep (insomnia), non-refreshing sleep, or excessive daytime sleepiness. Because of the very brief nature of the many arousals triggered by snoring, patients with UARS are typically unaware of these awakenings and generally do not know that they may be snoring if it were not for the witnessed reports from a bed partner or family member.


Obstructive Sleep Apnea – A potentially serious sleep disorder in which breathing repeatedly stops and then starts again during sleep. It is caused by collapse and blockage of the upper airway. This can be a life threatening condition if not treated properly.

​Precision Diagnostics and Treatments for Snoring and Sleep Apnea​

  • Polysomnography  

  • Sleep Endoscopy

  • CPAP Optimization

  • Oral Appliance

  • Myofunctional Therapy

  • Frenuloplasty


  • Turbinate Reduction

  • Nasal Surgery

  • Tonsillectomy / Adenoidectomy

  • Uvulopalatopharyngoplasty

  • Hypoglossal Nerve Stimulator (HGNS)


  • Genioglossus Advancement

  • Maxillary Expansion

  • MMA: Maxillary Mandibular Advancement

Frenuloplasty- A procedure to correct tongue tie (ankyglossia) by using sutures to lengthen the lingual frenulum for patients with restricted tongue range of motion.

Nasal Obstruction – A common complaint of blockage or having difficulty breathing out of one or both the nostrils that is caused by inflammatory or structural problems of the nose.


Deviated Septum- A condition in which the nasal septum -- the bone and cartilage that divide the nasal cavity of the nose in half -- is significantly off center, or crooked, making breathing difficult. 


Nasal Valve Collapse - A relatively common cause of nasal obstruction characterized by collapse of the cartilaginous part of the nasal tip with inspiration. 






Dr. Zaghi and our team at The Breathe Institute are proud to be continuing to provide online screenings for those suffering from nasal obstruction, snoring, sleep apnea, tongue-tie or for anyone seeking a healthier roadmap to better breathing and overall wellness.
