Objective: Paranasal sinus osteomas (PNS) are rare, most common benign bone tumors of the paranasal region that can remain asymptomatic until they reach a certain size and are usually diagnosed incidentally. In this study, the authors aimed to evaluate the factors determining a surgical approach to paranasal sinus osteomas.

Methods: Twenty-two patients who underwent surgery for PNS osteoma between January 2012 and December 2018 were included in this retrospective study. The demographic characteristics, tumor location and size, symptoms, surgical techniques, and postoperative complications were analyzed retrospectively. The relationship between the location and size of the osteoma and a surgical approach was investigated.

Results: Of 22 patients who underwent surgery for PNS osteoma, eight were female (36.3%) and 14 were male (63.7%). The mean age of the patients was 39.1 years, the range is 21-54 years. In decreasing frequency, osteomas were found to be, according to their paranasal sinus location, as follows; ten (45.4%) patients had ethmoid sinus, eight (36.3%) patients had frontal sinus, three (13.6%) patients had maxillary sinus, and one (4.5%) had frontal and ethmoid sinus osteomas. The tumor was excised by way of the osteoplastic flap technique in five (22.7%) cases with frontal sinus osteomas greater than 2 cm. A combination of the Caldwell-Luc and transnasal endoscopic techniques were used in three (13.6%) cases with patients with maxillary sinus osteomas. Tumor excision was performed with the lateral rhinotomy technique in one case (4.5%) with a giant osteoma located in the ethmoid sinus. Osteoma excision was performed with a transnasal endoscopic approach in the remaining 12 patients with ethmoid (n = 9) and frontal sinus (n = 3) involvement.

Conclusions: Although there is an increasing tendency to minimally invasive and less morbid transnasal endoscopic approaches in PNS osteoma surgery, open surgical techniques and combined approaches should be preferred for ethmoid and frontal sinus localized osteomas with potential complications and which extend beyond the boundaries of the paranasal sinuses. PNS osteoma size and localization, surgical equipment, endoscopic sinus surgery experience and experience in open surgical techniques are the determinants for the surgical approach in PNS osteoma surgery.
