Thin membranous anterior and posterior fontanelle areas below the OMC can rupture forming a perforation, accessory maxillary ostium (AMO), that increases antral airflow changing the anatomy and function of the sinus. The purpose of this study was to report the first case series of CRS patients who had undergone repair of fontanelle defects aiming to reconstruct normal structures.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Between 2011 and 2017, a total of 157 perforations were diagnosed and repaired in 121 of 525 consecutive endoscopic sinus operations performed by the author. Defects were 3 mm to 4 mm in size (range, 1 mm to 7 mm). A flap cut from the undersurface of the middle turbinate was used. In total, 101 patients received concurrent balloon catheter dilation (BCD), while 15 patients had only an AMO repair. The mean endoscopic follow\u2010up time was 16 weeks (range, 1 to 188 weeks).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 101 perforations were closed, 21 open, and 17 partially open. A history of earlier endoscopic sinus surgery (ESS) or BCD surgery, presence of nasal polyposis or whether the repair was made without simultaneous BCD did not influence the closure rate. Postoperative febrile sinusitis occurred in 26 patients.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Repair of AMO is in theory a beneficial and technically feasible office procedure with only transient side effects.
