Michigan Otolaryngology Surgery Associates

What Michigan Otolaryngology Surgery Associates does

Michigan Otolaryngology Surgery Associates (MOSA) is a private, physician-owned otolaryngology (ENT) specialty practice founded in 1979 and headquartered in Ypsilanti, Michigan. The practice delivers comprehensive medical and surgical ENT care across six Southeast Michigan locations — Brighton, Canton, Chelsea, Livonia, Saline, and Ypsilanti — serving patients from infants through the elderly. Service lines include general ENT, sleep apnea and snoring, balance disorders, pediatric ENT, ear disorders, nasal and sinus disorders, throat and thyroid disorders, voice disorders, head and neck oncology, and a full-service audiology department staffed by approximately ten audiologists offering hearing aids, vestibular testing, cochlear implants, and BAHA services.

MOSA's clinical differentiation rests on advanced procedural capabilities that are regionally rare: Transoral Robotic Surgery (TORS) using the Intuitive Surgical Da Vinci platform — with Dr. Paul T. Hoff holding the largest North American experience for sleep apnea — transoral laser microsurgery (TLM) for throat cancers performed by Dr. Jan Akervall, Inspire hypoglossal nerve stimulation (one of only three Michigan programs), sialoendoscopy pioneered by Dr. Senja Tomovic, drug-induced sleep endoscopy (DISE), videostroboscopy, and a broad in-office procedure menu (balloon sinuplasty, Vivaer, Latera, Clarifix, RhinAer, radiofrequency ablation). Surgical cases are performed primarily through Trinity Health Michigan hospitals and Beaumont Royal Oak, where MOSA physicians hold directorships and faculty appointments.

The business model is professional services revenue billed through insurance (Aetna, BCBS, Cigna, Medicare, Medicaid, United, and others) and patient co-pays collected at time of service. GTM is traditional referral-led — primary care physician referrals, direct patient inquiries, and a website/athenahealth patient portal for scheduling. Headcount is 51-100 employees including eight physicians, two physician assistants, and ten audiologists. No public financials, funding, M&A, or ownership change events are disclosed.
