Background & Objectives : Nowadays, coronary artery disease is the most common cause of death in developed countries and in the whole world. According to the WHO reports, it will be the main cause of death in 2020. Myocardial infarction is the most common diagnosis among hospitalized patients in industrialized countries. This disease causes more mortality and morbidity than others. Coronary artery bypass grafting surgery (CABGS) is one of the common treatments for ischemic heart disease but it may have some complications. In this study we wanted to evaluate the incidence of CABGS complications in Imam Khomeini Hospital of Ardabil in the first month after CABG.

  Methods: This study was a cross sectional analytic descriptive type and performed on all of the patients underwent CABGS in Imam Khomeini Hospital during 2011-2012. All of the data from patients (like demographic, past medical history, physical exam findings, paraclinical findings and CABGS complications) were inserted in special forms after gathering, and analyzed by SPSS v.16.

  Results: In this study, 211 patients were studied. About 145 (68.72%) of them were male and 66 (31.28%) were female. Seventy patient (33.17%) were more than 70 years old. About 33.22% of patients had a history of cigarette smoking and 9.95% were opioid abused. The 34.12% of patients had hypertension (HTN) history, 40.28% diabetes mellitus (DM), 17.06% history of hyperlipidemia and 63.98% had a history of the previous MI. Chest pain was the most common complication among the patients (93.36%). According to our study the prevalence rate of post CABGS complications were: bleeding after surgery 13.27%, postoperative myocardial infection 8.05%, neurological disorders 12.32%, renal complications 2.36%, respiratory symptoms 11.37% and 34.59% for cardiovascular complications. Also the total mortality was 5 (2.36%) persons. The data analysis showed that there was a significant relationship between sex with survival status, local infection and neurological disorders, and also there was a significant relationship between age with post CABGS survival, bleeding after surgery and renal complications. There was also a significant relationship between DM and post CABGS survival, local infections and respiratory complications and between HTN and local infections.

  Conclusion: According to the results of this study, the most common post CABGS complications were cardiovascular complications, especially arrhythmias.

  Background & objectives: Deviation of the nasal septum is a common cause of unilateral or bilateral nasal airway obstruction and may follow nasal and midface trauma. Patient complaints of airway obstruction that are consistent with intranasal physical findings often lead to septoplasty and turbinate surgery. Severe nasal septal deviation leads to complete nasal obstruction and disturbs air passage from nostrils, however the effect of septal deviation and nasal obstruction surgery (septoplasty) on Eustachian tube function and middle ear pressure is controversial and isn’t clear. Whereas many of surgeons do not believe the considerable effect of septoplasty on Eustachian tube function and middle ear pressure, so they do not recommend this procedure before middle ear surgery. On the other hand, some have an idea that septoplasty has significant effect on middle ear pressure suggesting this procedure before ear surgery like tympanoplasty.

  Methods: This prospective analytical-descriptive study was conducted on seventy patients from 18 to 65 years of age who underwent septoplasty due to severe septal deviation leading to nasal obstruction in Beesat Hospital during one year (2012-2013). Middle ear pressure and Eustachian tube function on the septal deviated side and contralateral side before and after septoplasty (3 to 6 months later) were measured through tympanometry and Eustachian tube function test (Toynbee test). The comparison between pre- and postoperative ETF tests and middle ear pressures was assessed using Paired –T test and p-value of less than 0.05 was considered as statistically significant.

  Results : This study revealed that comparison between mean values of pressure in the deviated and contralateral side has no significant statistical difference before and after septoplasty. Also comparison between Eustachian function in the deviated side and contralateral side showed no significant difference before and after septoplasty.

  Conclusion : The septoplasty didn’t have considerable effect on Eustachian tube function and middle ear pressure three to six months after surgery, and on the basis of pre- and post operative measurements it was stated that surgical correction of a nasal septal deviation before ear surgery such as tympanoplasty is not justified.
