IntroductionDental implants have been associated with the occurrence of postoperative rhinosinusitis. In some patients, preoperative sinus lifting must be performed to increase the chances of successful implant placement. This retrospective study examines the relationship of dental implants after sinus lifting with the occurrence of postoperative rhinosinusitis.MethodsA total of 268 dental implants were inserted in 94 patients (62 Males, 32 Females) between 2011–2013. The ages ranged from 29–71 (in males) and 33–64 (in females). Additionally, bilateral sinus lifing was performed in 51 patients, and unilateral sinus lifting was performed in 43 of the patients. Patients were evaluated for sinus pathology for a period of 5–47 months postoperatively using a satisfaction questionnaire, conventional radiographic examination, and nasal endoscopic examination.ResultsFour of the patients (4.2%) had a complication of postoperative sinusitis and were treated medically. In one patient, the implant was unsuccessful (even after treatment) and was removed. None of the patients needed surgery due to the sinusitis or any associated complications.ConclusionThe risk for postoperative rhinosinusitis was found to be higher in patients who suffer from chronic sinusitis and in cases in which a large amount of graft was utilized for sinus lifting. These predisposing factors need to be considered when evaluating patients for dental implants and sinus lift procedures.Electronic supplementary materialThe online version of this article (doi:10.1186/1746-160X-10-53) contains supplementary material, which is available to authorized users.
The aim of this study was to investigate the effect of controlled hypotension on cerebral oxygen saturation (rSO2) using near infrared spectroscopy (NIRS) and evaluation of postoperative cognitive function in patients undergoing rhinoplasty. Fifty adult patients who were scheduled for elective rhinoplasty surgery and required controlled hypotension were enrolled in this prospective study. Controlled hypotension was provided using a combination of propofol and remifentanil infusion supplemented with nitroglycerin infusion as necessary. rSO2 was evaluated during controlled hypotension by NIRS. Cerebral desaturation was observed in 5 out of 50 patients (10 %) during hypotensive anesthesia. The greatest decrease from baseline was 28 % when MAP was 57 mmHg. In both non-desaturated and desaturated patients, postoperative MMSE scores were significantly lower than preoperative scores. There was a 4 % decrease in the non-desaturated patients and a 7 % decrease in the desaturated patients when preoperative and postoperative MMSE scores were compared. A decline in cognitive function 1 day after surgery was observed in 23 patients (46 %) and in all patients with intraoperative cerebral desaturation. The current study showed that even if SpO2 is in the normal range, there might be a decrease of more than 20 % in cerebral oxygen saturation during controlled hypotension.
We conducted a retrospective study to compare open and endonasal (closed) approaches to extracorporeal reconstruction of severe caudal septal deviations. From January 1, 2010, through December 31, 2013 patients with severe caudal septal deviation underwent corrective surgery at our hospital. Of this group, 33 patients (mean age: 32 yr) underwent extracorporeal septoplasty via an open approach, and 45 patients (mean age: 35 yr) underwent treatment with a new procedure that we developed: subtotal extracorporeal septoplasty through a closed approach, which we call "marionette septoplasty. " In addition to demographic data, we compiled information on surgical time, the duration of postoperative edema, the degree of postoperative pain, and differences between pre-and postoperative nasal function and tip support in both groups. We found that our marionette septoplasty procedure required significantly less surgical time and resulted in a significantly shorter duration of postoperative edema than did open septoplasty, while there was no statistically significant difference between the two procedures in the degree of pain. Following surgery, nasal function in both groups improved significantly, without any significant difference between the two. Finally, we documented improved tip support in all 78 patients. Our results show that marionette septoplasty produces the same functional results as does open septoplasty while requiring less surgical time and shortening the healing period.
Exposure to the electromagnetic field emitted by cellular telephones, for 6 hours a day for 30 consecutive days, had no effect on the hearing of newborn or adult rats, at the outer ear, middle ear or cochlear level.
Olfactory dysfunction and migraine has been associated for a long time. In this study, we planned to compare olfactory functions in patients with migraine and osmophobia with patients having migraine but no osmophobia, in addition with a normal control group using "Sniffin' Sticks" test. The main distinction of this study is that all qualitative and quantitative properties of olfactory functions; threshold, discrimination and identification, are evaluated separately and jointly. Thirty healthy person aged between 16 and 56 (18 women, 12 men) and 60 migraine patients aged between 15 and 54 (39 women, 21 man) were included in the study. All patients have been inquired about osmophobia and have been assessed with Hedonic tone assessment. Osmophobia has been tested for perfume, cigarette smoke, leather, stale food, soy sauce, fish, spices and coffee smells. Olfactory functions has been assessed with "Sniffin' Sticks" smell test. Thresholds, discrimination and identification have been determined for each patient. In migraine patients with osmophobia, threshold was 7.75 ± 2.3, in migraine patients without osmophobia threshold was 8.25 ± 1.5 and threshold was 10.75 ± 1.3 for the control group. Discrimination score was 6 ± 1.2 in migraine patients with osmophobia, 9 ± 0.8 in patients without osmophobia and was 12 ± 1.4 in the control group. In migraine patient with or without osmophobia Threshold/Discrimination/Identification (TDI) scores were lower than the control group. The most important parameter in our study is that discrimination scores were especially lower in patients with osmophobia. We believe that this decrease in discrimination in migraine patients with osmophobia; who claim that they smell everything and they are sensitive to all smells, is significant. Further studies about smell discrimination will help better understand some conditions; especially anosmia and hyposmia after upper respiratory tract infections and parosmia.
The aim of the study was to investigate the relationship between nasal septal deviation and the middle turbinate hypertrophy using computed tomography. In this retrospective analysis, we examined 77 patients with nasal septal deviation. The mucosal and bone structures of the middle turbinate and the angle of the septum were measured using radiological analysis. Measurements of the middle turbinate on the convex side were compared to those on the concave side. Measurements of the bony and mucosal structure area of the middle turbinate were significantly greater than those on the concave side. The dimensions of medial mucosa thickness and bone thickness were not significantly different between the convex and concave sides. No significant correlation was found between the angle of deviation and other parameters. The present findings suggest that compensatory middle turbinate hypertrophy was caused both by conchal bone growth and mucosal hypertrophy in patients with nasal septal deviation.
