The anatomy of the sinonasal area has a very wide rage of anatomical variations. The significance of these anatomical variations in pathogenesis of rhinosinusitis, which is the commonest disease in the region, is still unclear. The aims of the study were to compare the rate of sinonasal anatomical variations with development and severity of chronic rhinosinusitis patients. CT scan of paranasal sinuses images of 99 individuals were retrospectively reviewed. 65 cases of chronic rhinosinusitis (study group) who had undergone endoscopic sinus surgery were compared with 34 cases without chronic rhinosinusitis (control group). Also in study group Lund-Mackay score of the sinus disease were calculated and compared to the rate of related anatomical variations. There were 74 (74.7 %) males and 25 (25.2 %) females with ages ranging from 13 to 70 years (mean 32.2 years). The anatomical variations recorded were: Septal deviation 47 (72.3) in study and 25 (73.5 %) in control group, concha bullosa 27 (41.5 %) in study and 18 (52.9 %) in control group, overpneumatized ethmoid bulla 17 (26.1 %) in study and 14 (41.1 %) in control group, pneumatized uncinate 3 (4.6 %) in study and 3 (8.8 %) in control group, agger nasi 42 (64.6 %) in study and 19 (55.8 %) in control group, paradoxical middle turbinates 9 (13.8 %) in study and 4 (11.7 %) in control group, Onodi cell 6 (9.2 %) in study and 2 (5.8 %) in control group, Haller's cells (infraorbital ethmoid cell) 9 (13.8 %) in study and 7 (20.5 %) in control group. None of these results were statistically significant between study and control group (p [ 0.05). Lund-Mackay score (which was assumed to show the severity of the disease) of the maxillary, ethmoid and frontal sinus were calculated and compared to rate of septal deviation, concha bullosa, agger nasi cells. No significant correlation was conducted (p [ 0.05). The results of study showed no statistically significant correlation between sinonasal anatomical variations and pathologies of the paranasal sinus. Also these anatomical variations did not increase the severity of pre-existing sinusitis significantly. Level of Evidence This is a retrospective cohort study (2b).

We measured the nasal mucociliary activity in total laryngectomy patients, and to compare among themselves, smokers, diabetics and normal population besides that to investigate the short and long term effects of total laryngectomy on nasal mucosa. The study includes 39 patients who had total laryngectomy between the January 1998-August 2005 and 36 volunteer healthy individuals. To examine the early and late changes on nasal mucosa the patients that had total laryngectomy separated into two groups as operated before August 2003 (> 2 years), as operated after August 2003 (< 2 years). Moreover diabetic patients and smokers are differently grouped. This study is performed in Haydarpasa Numune Hospital for Research and Education, Department of Otorhinolaryngology, between May 2005-September 2005. Mucociliary clearance measurement is performed by saccharin test for all patients and control group. The mucociliary clearance of the patients (diabetics-nondiabetics, smokers-non smokers) are measured and examined if they show any difference among themselves. For the patients operated between the dates August 2003-2005 (< 2 years group) the nasal mucociliary clearance time average is found 8,15 +/- 2.06 min., for the patients operated before August 2003 (> 2 years group) the mean time is found 23.79 +/- 5.58 min., for the control group the mean time is found 14.5 +/- 3.55 min In operated group the patients who are diabetics has longer mucociliary clearance time than nondiabetics, and the difference is statistically significant. Similarly in control group diabetics has longer mucociliary clearance time than nondiabetics. As another parameter smoking, comparing the groups among themselves, smokers have longer mucocilliary clearance time than nonsmokers. In total laryngectomy patients hypersecratory phase is produced in early period and nasal mucosal clearance is increased. On the other hand, dependent on chronic infections nasal mucosa is atrophied and nasal mucosal clearance is disrupted. However smoking and diabetes mellitus also damage the mucocilliary clearance.

Aminoguanidine and melatonin alone achieved an increase in regeneration after peripheral facial nerve neurorrhaphy, but methylprednisolone did not. The best healing was determined in the AG group.

The aim of this study is to compare the inlay butterfly transcanal cartilage tympanoplasty with the conventional underlay tympanoplasty. Operation time, pre- and postoperative hearing levels, successful closure rate of tympanic membrane (take rate) and long-term re-perforation in dry perforated chronic otitis media were evaluated. The study design consists of case series with a chart review. The study settings are tertiary referral center. Of the 72 patients (age range 14-57 years) with dry perforated chronic otitis media, 29 patients underwent inlay butterfly transcanal cartilage tympanoplasty (group 1) and 43 patients underwent conventional underlay tympanoplasty without mastoidectomy (group 2) between January 2010 and June 2012. The outcome measures were the duration of surgery, "take rate" at the 30th postoperative day and the audiometric results at the 45th postoperative day. Long-term re-perforation was evaluated at least postoperative 1 year. The graft take rate was 96.5 % in group 1 and 90.7 % in group 2 at the 30th postoperative day (p > 0.05). Mean air-bone gap was improved from 18.8 ± 8.09 to 11.9 ± 7.12 dB in group 1 and from 21.9 ± 7.32 to 11.6 ± 8.43 dB in group 2. The improvement of air-bone gap in both groups was statistically significant (p < 0.05) but the improvement between the groups was not statistically significant (p > 0.05). The average duration of the surgery was 29.9 ± 5.38 min for inlay tympanoplasty group and 58.9 ± 12.1 min for underlay tympanoplasty group (p < 0.05). Two patients in group 2 had re-perforations after an initial take of the graft in 1-year follow-up period. Inlay butterfly transcanal cartilage tympanoplasty is a good choice in selected cases. Although this technique has the similar take rate and audiological results with conventional underlay tympanoplasty, it is a time-saving procedure.

SummaryStatement of problem: Surgery for nasal obstruction is performed to give a subjective benefit. We aimed to evaluate the surgical management of the nasal obstruction in the patient's perception. Methods of study:The study was performed prospectively with 134 patients over the age of 18. They were allotted to three groups according to the level of nasal obstruction by clinical examination. The G1 group had only a deviated nasal septum (DNS), G2 had DNS and hypertrophy of inferior turbinates, and G3 had nasal valve problems in conjunction with DNS. All the patients had surgery focused on obstructive pathologies. The study was conducted using three different scoring systems to determine the patients' evaluation of the surgical procedures. Results:The study included more man than woman, with a mean age around 28 (wide range). Twenty six patients were in G1, 73 patients in G2 and 35 patients in G3. Total and general Glasgow Benefit Inventory (GBI) scores for each group showed improvement postoperatively. There was a significant difference between the groups for general GBI score, and Post-hoc test showed that the improvement of G1 was greater than of G3. The influence of the surgery on physical health, psycho-social function and social interaction scores for each group showed no changes postoperatively. There was a significant improvement in all Nasal Obstruction Septoplasty Effectiveness (NOSE) scores and Likert Scale scores for each group. The improvement of G1 and G2 were greater than G3 on the Likert Scale. Conclusion:Surgical management targeted to the region of obstruction improves symptoms and benefit in the patient's perception.
