It is well established that symptoms are very important in the diagnosis of CRS. However, two major symptoms are insufficient for diagnosis. Therefore, endoscopy and CT have important differential diagnostic roles. Our study showed that in patients with three major symptoms, CT pathology may be sufficient for definitive diagnosis. However, in patients with two major symptoms such as nasal discharge and/or low grade nasal polyposis, endoscopy becomes considerably more important due to inspective findings. If no endoscopic findings are found, the importance of the CT scans is increased.

In this study, the authors observed that septoplasty has positive effect on cardiopulmonary functions in the patients with nasal obstruction due to nasal septum deviation. The authors also claim that septoplasty may be a preventive procedure for future pathologies of cardiopulmonary functions.

Percutaneous lateral osteotomy technique was found to result in less bone and periost trauma and better bone healing compared to the endonasal osteotomy technique.

A rare case of posttraumatic bilateral abducens palsy is presented. A 17-year-old male patient referred to our clinic because of complaints of diplopia, difficulty in opening his mouth, pain in the face, dyspnea, and chest pain after head trauma from a motor vehicle accident. The patient was not able to abduct eyes bilaterally, and diplopia occurred in the lateral gaze. All other extraocular movement was intact. He also had a mandibular fracture and bilateral pneumothorax. Computed tomography scan of the cranium showed no intracranial or extracranial hemorrhage, no mass effect, and no edema. No abnormalities were seen in the orbits, sinuses, skull base, and calvarium. For the treatment of sixth cranial nerve palsy, we applied corticosteroid therapy and waited for spontaneous recovery. During follow-up, at 3 months after discharge, he showed marked improvement in his ocular mobility and alignment without any residual limitation of abduction bilaterally. A bilateral sixth nerve palsy is rarely seen after a head trauma without cranial pathologic findings, and corticosteroid therapy may have beneficial effects during treatment besides spontaneous resolution.

We report a histologically and mycologically proven sinonasal mucormycosis case causing palatal necrosis in a nondiabetic patient with renal failure. Mycological examination of Giemsa stained imprinted tissue preparations revealed abundant yeast-like cells besides the typical mucoraceous hyphae. The fungus was isolated from surgical specimens and identified as Rhizopus oryzae by phenotypic and genotypic tests. Laboratory studies were performed to investigate the association of the yeast-like cells observed in tissue specimens and the fungus recovered in culture. In vitro induced yeast-like cell development of the case isolate was found under certain growth conditions and documented by photomicrographs.
