HEIDER C, Claudia; RIBALTA L, Gloria  y  KRAUSS M, Karin. Mucus recirculation in maxillary rhinosinusitis. Rev. Otorrinolaringol. Cir. Cabeza Cuello [online]. 2013, vol.73, n.1, pp.39-44. ISSN 0718-4816.  http://dx.doi.org/10.4067/S0718-48162013000100006.

Introduction: Recirculation of mucus between the maxillary sinus natural ostium and adjacent openings disturbs mucociliary clearence leading to secretions accumulation and persistent infection, perpetuating the inflammatory phenomenon. Aim: Describe our experience in the diagnosis and treatment ofpatients with maxillary rhinosinusitis (chronic or acute recurrent) and maxillary recirculation. Material and method: Descriptive and retrospective study. Clinical records, radiologic characteristic, nasal endoscopies and surgical findings were reviewed. Results: 8 patients, mean age of 43 years. All of them had prior history of maxillary sinus surgery. Clinical presentation was maxillary rhinosinusitis, chronic or acute, with frequent episodes ofreagudization (3 episodes/year). The diagnosis was made by endoscopic nasal examination that showed mucus recirculation between natural and accessory ostium. Endoscopic sinus surgery was done in 5patients in order to communicate the accessory to the natural ostium, leading to a decrease in the number of exacerbations. Conclusions: Maxillary recirculation must be suspected in patients with maxillary rhinosinusitis (chronic or acute recurrent) who have had prior surgical procedures that involve the maxillary sinus. The diagnosis is based on the observation of the recirculation phenomenon in the nasal endoscopy. The treatment is surgical and depends on the location of the accessory ostium and the permeability of the natural ostium.
