Abstract

Introduction Maxillary sinus pathologies, such as sinonasal polyposis, is a risk factor for complications of maxillary sinus floor augmentation procedures or sinus lift. No studies in the literature have investigated sinus lift candidates with sinonasal polyposis. Clinical case: A 65-year-old woman was referred to oral surgery for implant rehabilitation at site 15. Sinus lift was indicated but sinonasal polyposis was diagnosed. After medical-surgical treatment of the sinonasal polyposis with an ear, nose and throat surgeon, sinus lift surgery was successfully performed. Discussion: Sinonasal polyposis is a diffuse chronic rhinosinusitis characterized by bilateral inflammatory polyps in nasal cavity or middle meatus. According to the latest guidelines of the French Society of Otorhinolaryngology and Head and Neck Surgery, the sinus lift surgery is possible with stable controlled sinonasal polyposis. Conclusion: Sinus lift surgery for patients with sinonasal polyposis is a multidisciplinary treatment involving ear, nose and throat and oral surgeons. Stable controlled sinonasal polyposis patients receive the same pre-implant management as healthy patients.
