Öğe Butylcyanoacrylate tissue adhesive for columellar incision closure(Headley Brothers Ltd, 2001) Ozturan, O; Miman, MC; Aktas, D; Oncel, SCosmetic outcome of the columellar incision closure in external rhinoplasty patients has been a subject of discussion. This study was conducted to assess whether tissue adhesives provide an alternative option for sutureless closure of columellar skin incisions for cases utilizing open technique rhinoplastic surgery. One hundred and one patients undergoing external rhinoplasty were randomized to either topical application of butylcyanoacrylate or polypropylene sutures for columellar skin closure. The majority of tension on the wound edges was taken up using 5-0 chromic catgut. Cosmetic outcomes were evaluated by two otolaryngologists independently using visual analogue and Hollander wound evaluation scales in a blinded manner. There was no statistically significant difference in cosmesis between the surgeons' evaluation scores for either type or repair of the columellar incision. Since the tissue adhesive forms its own protective barrier, post-operative care is simplified. Closure with adhesives eliminates the need for post-operative suture removal requiring an extra visit that should lead to more efficient use of physician and patient time. Butylcyanoacrylate performs cosmetically as well as standard suture closure of columellar skin incision used for external rhinoplasty.Öğe Glomus jugulare(Sage Publications Ltd, 2002) Miman, MC; Aktas, D; Oncel, S; Ozturan, O; Kalcioglu, MT[Abstract Not Available]Öğe Maxillary sinus hypoplasia(Int Rhinologic Soc, 2002) Erdem, T; Aktas, D; Erdem, G; Miman, MC; Ozturan, OMaxillary sinus hypoplasia (MSH) is an uncommonly, encountered condition by otolaryngologists. Pie computerized tomography (CT) scans provide valuable data about the anatomic details of the paranasal sinuses. MSH may, be misdiagnosed as an infection or a neoplasm of the maxillary, sinuses. Variations of the other paranasal structures, especially the uncinate process associated with MSH were defined. MSH shows three distinct hypoplasia patterns. Type I MSH characteristics are mild hypoplasia of the maxillary sinus, normal uncinate process and a well-developed infundibular passage. Significant hypoplasia of the maxillary, sinus, hypoplastic or absent uncinate process and absent or pathologic infundibular passage are seen in Type II MSH. Type III MSH is characterized by the absence of an uncinate process and cleft-like maxillary, sinus hypoplasia. In this study a series of 18 patients with MSH were presented. Twelve cases of unilateral and 6 cases of bilateral maxillary, antrum hypoplasia were evaluated and 13 MSH hype 1, 7 MSH type II and 4 MSH type III were detected. Three ethmomaxillary sinuses, an overpneumatized posterior ethmoid cell into the orbit and the maxillary sinus were determined. Our series showed that the uncinate process anomalies related to MSH malY lead to inadvertent orbital complications and therefore should be kept in mind.Öğe The relationship between the concha bullosa, nasal septal deviation and sinusitis(Int Rhinologic Soc, 2003) Aktas, D; Kalcioglu, MT; Kutlu, R; Ozturan, O; Oncel, SObjectives: To evaluate the possible relationship between concha bullosa, nasal septal deviation and sinusitis. Patients and methods: Paranasal sinus computed tomography scans of patients suffering from rhinosinusitis were examined. Fifty-four patients with concha bullosa were included in the study. The relationship between concha bullosa, nasal septal deviation and sinusitis was investigated. Results: A statistically significant relationship between unilateral concha bullosa and nasal septal deviation was found (p<0.01). The relationships of unilateral and bilateral concha bullosa with sinusitis, and bilateral concha bullosa with nasal septal deviation were not statistically significant (p>0.05). Conclusion: In order to define the relation between the concha bullosa, nasal septal deviation and sinusitis, more detailed investigations are needed.Öğe The relationship between traumatic tympanic membrane perforations and pneumatization of the mastoid(Karger, 2000) Aktas, D; Kutlu, RWe evaluated the possible relationship between tympanic membrane perforations resulting from blast trauma or slap and pneumatization of the mastoid cells. A total of 25 male patients with tympanic mem bra ne perforations resulting from blast injury (n = 7), slap (n = 17), and football hit (n = 1) and 20 healthy male volunteers without any ear problem had temporal bone computed tomographic scans in the axial plane, parallel to the infraorbitomeatal line, with 2 mm slice thickness and 2-mm intervals using bone algorithm with a ProSpeed Spiral tomography machine. The area of air cells in each slice was measured using trace and area measurement functions of the tomography machine, and by multiplying the resulting area by slice thickness, the volume of each slice was calculated. For each ear, the total of volumes of air cells was calculated by adding the volumes of each slice containing air cells. The calculated volumes of mastoid cells were evaluated by comparing microscopic findings. Both patient and control groups consisted of males, and their ages ranged from 17 to 32 (mean 24.5) years. Microscopic examinations revealed that perforations were frequently located in the lower quadrants and that most of them were less than 3 mm. There were no pars flaccida and marginal perforations. Ossicular chain destruction was noted neither in temporal bone tomographic nor during intraoperative examinations. The mean (+/- SD) volumes of right and left ear mastoid air cells in patient and control groups were 6.92 +/- 2.45 vs. 7.00 +/- 2.59 cm(3) and 9.04 +/- 4.55 vs. 8.95 +/- 4.53 cm(3), respectively, and the differences were not statistically significant. It was found th at the level of mastoid pneumatization has no statistically significant effect on tympanic membrane pathologies due to blast or other injuries. Copyright (C) 2000 S.
