    Ancient schwannoma of the parotid gland: A case report and review of the literature
    (Churchill Livingstone, 2006) Bayindir, T; Kalcioglu, MT; Kizilay, A; Karadag, N; Akarcay, M
    Schwannomas are encapsulated benign tumours arising from nerve sheath cells, of which ancient schwannoma is one of five variants. Since the first description, only a few ancient schwannomas have been reported in different locations in the head and neck region. In the parotid gland, this tumour is very rare. In this report, a 41-year-old female patient with an ancient schwannoma of the parotid gland is presented and the data of this patient compared with other (comparable) cases described in the literature.

    Effects of the chorda tympani damage on submandibular glands: scintigraphic changes
    (Cambridge Univ Press, 2004) Yagmur, C; Miman, MC; Karatas, E; Akarcay, M; Erdem, T; Ozturan, O
    The aim of this study is to compare the scintigraphic results of a denervated submandibular gland with the contralateral normal side in patients with unilateral chorda tympani damage. Sixteen patients (11 women and five men with a mean age of 27) with unilateral proven chorda tympani damage during their previous ear surgery were included in the study. The perfusion ratio (PR), concentration ratio (CR) and stimulated excretion ratio (SER) were calculated scintigraphically and the results from the salivary glands on opposite sides were compared. For submandibular glands, the perfusion ratio (PR), concentration ratio (CR) and stimulated excretion ratio (SER) were found to be 0.65 +/- 0.21, 0.70 +/- 0.21, 0.79 +/- 0.37, respectively. All ratios resulted from statistically decreased radioactivity accumulation on the affected side (P<0.05). Chorda tympani damage negatively affects the function of the ipsilateral submandibular glands despite the absence of atrophy. Dynamic salivary gland scintigraphy is a practical and valuable method of disclosing the decreased capacity of perfusion, concentration and secretion function in unilateral neurological deprivation.

    Nasal pyriform aperture stenosis in adults
    (Ocean Side Publications Inc, 2004) Erdem, T; Ozturan, O; Erdem, G; Akarcay, M; Miman, MC
    Background: Congenital nasal pyriform aperture stenosis (CNPAS) leading to respiratory insufficiency in infants has been well documented. Nevertheless, the nasal pyriform aperture stenosis (NPAS) entity in adulthood has not been discussed at all. The normative data of the width of the pyriform aperture, which has not been revealed before, is necessary for evaluation of the adult subjects with nasal bony inlet stenosis. The aim of this study was to define the normative data about the pyriform aperture width measured in 80 adult subjects with paranasal sinus symptoms without nasal obstruction. and, additionally, to report the surgical results of two representative cases with NPAS. Methods: The nasal bony inlet width measurements have been achieved in axial computerized tomographic sections to establish normative data. The maximal distance between the nasal processes of the opposite maxillary bones was measured. Two adult males complaining of nasal obstruction with overt pyriform aperture stenosis were treated surgically via a sublabial approach. Results: The mean widest dimension of the nasal pyriform aperture was 21.6 +/- 2.2 mm (range, 17-27 mm) in 80 adult subjects. This width was 21.9 +/- 2.1 mm (range 18-27 mm) in men and 21 +/- 2.2 mm (range, 17-26 mm) in women. Stenotic pyriform apertures in two patients were widened surgically by drilling via a sublabial approach from 12 and 10 mm to 24 and 21 mm, respectively. Conclusion: NPAS should be included in the list of differential diagnosis for nasal obstruction. Surgical enlargement using a sublabial approach was found an effective and adequate treatment in pyriform aperture stenosis.
