    The intracranial complication of acute isolated sphenoid sinusitis
    (2002) Unlu H.Halis; Aslan A.; Goktan C.; Egrilmez M.
    Acute isolated sphenoid sinusitis is a rare, potentially destructive entity, which has indistinct clinical findings and non-specific symptoms. Hence, it can be easily be misdiagnosed. We present and discuss a case of an isolated sphenoiditis with intracranial complication. © 2002 Elsevier Science Ireland Ltd. All rights reserved.

    Osteochondroma of the posterior nasal septum managed by endoscopic transnasal transseptal approach
    (2002) Unlu H.H.; Unlu Z.; Ayhan S.; Egrilmez M.
    A case of osteochondroma of the posterior nasal septum is presented. A 57-year-old female patient presented with a history of bilateral nasal obstruction for 20 years. To the best of our knowledge, this is the second reported case of an osteochondroma of the nasal septum. It was treated by endoscopic transnasal transseptal surgery.

    Facial growth after middle turbinate resection: An experimental study in the rabbit
    (OceanSide Publications Inc., 2003) Egrilmez M.; Mutlu C.; Unlu H.H.; Celik O.
    Background: The aim of this study was to determine the effects of total middle turbinate resection on midfacial growth through a morphometric analysis on an animal model. Methods: Twenty-eight male New Zealand white rabbits were used. The animals were divided into three groups: group 1, elevation and relocation of the nasal bone was performed; group 2, concha resection was performed; group 3, control group with no surgical procedure. The surgery was done at 8-10 weeks of age and the skull of each subject was sampled as they reached maturity. The determined distances then were measured by using landmarks identified on skull. The supplied data were evaluated by using the Mann-Whitney U test. Results: Deviation of the nasal axis to the opposite side of the resected concha and an increase in the width of nasal bone were observed only in group 2. In group 1, an increase of nasal bone length and zygomaticonasal distances was determined in both the operated and the unoperated sides of nasal bones. Conclusion: This animal experiment showed that operations on the nasal bone or concha resection affected the midfacial growth in rabbits. The effects of middle turbinate resection to midfacial development should be evaluated by additional studies. We recommend only limited, conservative surgical procedures on the middle turbinate, saving all the vital mucosa, periosteum, and bone.

    Surgical implications of anatomical landmarks on the lateral surface of the mastoid bone
    (Springer Paris, 2004) Aslan A.; Mutlu C.; Celik O.; Govsa F.; Ozgur T.; Egrilmez M.
    The aim of this study was to examine the relationships of the surgical landmarks on the lateral surface of the mastoid bone with the landmarks in a deeper location. Simple mastoidectomy was carried out without drilling over the linea temporalis inferior (LTI) on 20 adult temporal bones. The suprameatal spine, i.e., Henle spine (HS), variants were noted. Morphometric measurements were performed between these surgical landmarks, and their variations with pneumatization or HS types were evaluated. Three types of HS were identified: triangular, crest, absent. The HS-lateral semicircular canal distance was 15 mm on average and longer in bones with a triangular HS than a crest type HS (16.4 vs. 14.3 mm). The LTI was found to be located on average 4.7 mm inferior to the middle fossa dural plate (MFD). The LTI-MFD distance had a tendency to be longer in bones without an HS than with a crest type of HS (5.9 vs. 3.9 mm). Chorda tympani emerged from the facial nerve at the stylomastoid foramen in five specimens (25%). This anatomical organization was not correlated with the type of HS. Korner's septum (KS) was identified in nine bones (45%). It was present in eight of 16 (50%) bones with good pneumatization. No tendency for the existence of KS was found for any specific type of HS. This study confirms that the mastoid antrum is located 15 mm deep to the lateral surface of the mastoid bone. It should be expected to be longer in bones with a triangular HS. In addition, the MFD is located on average 5 mm above the LTI, which could be useful information for beginners or inexperienced surgeons. The ear surgeon should anticipate that the MFD might be longer in bones without an HS. © Springer-Verlag 2004.
