Abstract
Objective: Traditional surgeries of the nasal septum improve the nasal airway but recent development and advancement of the knowledge about endoscope has changed the treatment modality significantly. Endoscopic approach under good Illumination and magnification lessens the chance of injuring the vital structures and hence lessen the chance of complication. This study is done to compare the conventional method with endoscopic method.
Method: Total 60 cases of deviated nasal septum, refractory to conservative medical treatment were randomly selected ÷d into 2 equal groups. 30 patients underwent endoscopic Septoplasty and 30 patients by conventional method. All of them were followed up for 6 months.
Results: The age distribution was ranging from 16 to 60. Out of them 28 patients (93.33%) of endoscopic group and 25 patients (83.33%) on conventional group were relieved from symptom. In endoscopic Septoplasty group, along with Septoplasty functional endoscopic sinus surgery was carried out in 4 patients (13.33%). In conventional group 4 patients (16.67%) had intra and postoperative complications like excessive hemorrhage and septal perforation etc.7 patients (23.3%) of conventional Septoplasty group presented with recurrence or persistence of symptom within 6 months of surgery.
Conclusion: Though conventional Septoplasty is widely practiced by most ENT surgeons till now, the endoscopic approach can be considered as a better alternative.

Introduction
Nasal obstruction is one of the most common complain that an otolaryngologist faces on day to day practice [1]. Deviated nasal septum is the most common problem behind this. It not only causes breathing difficulty but also causes impaired aeration to the paranasal sinus’s causes’ recurrent infection to the paranasal sinuses [1]. Various techniques have been proposed for the correction of the different types of septal deviations in the past. The concept of submucosal resection was popularized and refined by Killian [2] and Freer [3] separately in the early twenties. Later Septoplasty was introduced with less and required excision of deviated portion only, where the surgery is to be done with the help of headlight, but it is a selfish surgery where the assistant can’t see the field and the structures to be resected [4]. In this traditional septal surgery, there is often over exposure, unnecessary manipulation of the septal anatomy by a large incision and by elevation of flaps on both sides of nasal septum [5].The advent of endoscope has revolutionized rhinology and has widened the horizon of rhinology. Lanza et al and Stammberger initially described the application of endoscopic technique for the correction of septal deformity in 1991 [4,6]. Furthermore in complex deformities, better correction is possible with the help of an endoscope since we can see the posterior deviation clearly. Endoscope also aided limited resection and thus more conservation by guiding precise shaving of septal cartilage [4].
Materials and Method
Study design
A simple random cross-sectional interventional study.
Place of study
Bangladesh Medical college Hospital, Dhanmondi, Dhaka.
Duration of study
Jan 2016 to July 2016 (6 months)
Sample size & Sampling method
A total 60 patients of symptomatic Deviated Nasal Septum (DNS) within the study period from Jan 2016 to July 2016 were randomly selected. After taking an informed written consent all the selected patients were evaluated with detailed history, clinical examination and proper investigations. All patients were operated under general anesthesia. Post operatively all patients were packed with antibiotic mixed conventional ribbon pack, that was removed on 2nd POD on conventional septoplasty group and 1st POD on endoscopic septoplasty group. Data were recorded and complied in a structured data sheet and data were analyzed.
Selection criteria
Inclusion criteria: Patients with symptomatic deviated nasal septum/ septal spur, refractory to conservative treatment.
a) Any malignant condition of nose & paranasal sinuses.
b) Acute infection of nose & paranasal sinus disease.
c) Diagnosed cases of Sino-nasal polyposis.
Data analysis
All data were analyzed and presented as both qualitative and quantitative data as applicable using SPSS (Statistical packages for social science) software.
Results
In the group of conventional septoplasty (CS), youngest patient was of 16 year and the oldest was 52-year-old. Among them most common age group was 21-30, total 14 (46.67%). In endoscopic septoplasty (ES) group the youngest patient was of 17 year and the oldest was 60-year-old and common age group was 21-30 years. In this study, the male was more common than female with a ratio of 1.86:1. Out of 60 patients, 55 patients (91.67%) had presented with nasal obstruction. The next common symptom was headache in 48 patients (80%). and postnasal drip was in 13 patients (21.67%). Least common symptoms were dry mouth, Hyposmia, epistaxis (Table 1).
Isolated DNS was the most common finding, 28 (46.67%). The next common was DNS with Hypertrophied inferior turbinate (HIT) 19/60 (31.67%), Septal Spur found in 13/60 (21.67%) cases. In ES group of patients some additional surgeries was carried out as the associated pathology was visible due to the light of endoscope. Along with septoplasty Functional Endoscopic Sinus Surgery was carried out in 4 patients, submucosal diathermy done in 7 cases (23.33%), other commonly performed procedure was ES with conchostomy, ES with turbinoplasty etc. In CS group only septoplasty was done in 20 patients (66.67%) and septoplasty with submucosal diathermy was done in 10/30 (33.33%) patients (Table 2). All patients from ES group were discharged on 1st POD, but in conventional group 25 patients (93.3%) were discharged on 2nd POD and 2 patients (6.67%) on 3rd POD. ANS pack was kept in all patients, in ES group pack removed on 1st POD and in most cases of CS pack removed after 48 hours. Nasal splint was kept in all of the cases. That was removed on 7th POD. Immediate complication (unusual primary haemorrhage) happened in 1 patient (3.33%) from ES group while it happened in 6 cases (20%) in CS group (flap tear in 4, septal perforation in 2) and delayed complication (Synechiae) in 2/30 (6.66%) cases of CS group. There was no long-term complication in ES group, but it was 12.27% 4/30 (2 synechiae, 2 septal perforation) in CS group though the septal perforation cases was repaired after 6 months by the same surgeon.
Post operatively all the patients were followed up on 7th, 30th day, then at 3rd and 6th month. During each visit the patients were asked about the benefit of the surgery and it was tabulated. During each visit, all patients were examined with 0° naso-endoscope. Out of 60 patients with nasal obstruction 28/30 patients (93.3%) from ES group and 25/30 (83.33%) from CS group were relieved of symptom. Concha bullosa in 2 patients (6.67%) and Posterior bony spur in 2 patients (6.67%) in CS group was found during endoscopic assessment. Patient’s satisfaction was 93.3% in endoscopic septoplasty and 76.67% in conventional group.
Discussion
Nasal obstruction due to DNS is a common problem encountered by otolaryngologist [1]. To relieve this nasal obstruction septoplasty is the commonly performed surgical procedure [7]. In traditional head light based septal surgery there is poor illumination and less accessibility to posterior septum leads to over exposure, unnecessary manipulation of septal anatomy and more resection [5]. The advent of endoscope has revolutionized rhinology and has widened the horizon of rhinology [8]. The nasal endoscope allows precise preoperative identification of the septal pathology and its associated lateral nasal wall abnormalities and helps in better planning of endoscopic aided septal surgery [7]. Endoscopic septoplasty is a directed septoplasty and an effective technique that can be performed safely alone or in combination with endoscopic sinus surgery/endoscopic DCR etc. [8]. This procedure provides very good Illumination and easy approach to posterior bony spur and an excellent teaching tool [4,8]. Till date several studies have been conducted to establish these ideas and the results of maximum studies are similar.
In several studies [6,9] the most common age group belongs to 2nd and 3rd decades. In this study, most common belongs to 3rd decade, that is in concordance with above studies. Krisna, et al. [9] reported a male preponderance in the comparative study of conventional versus endoscopic septoplasty [9], that is in concurrence with our study, where there is a male female ratio of 1.86:1.There are many studies [6,10], where nasal obstruction is the most common complain followed by headache, post nasal drip, dryness of mouth, epistaxis, hyposmia etc. In our study of 60 cases, 55 patients (91.67%) had presented with nasal obstruction. The next common symptom was headache in 48 patients (80%), dryness of mouth was present in 12 patients (40%), Hyposmia was present in 5 patients (16.67%) (Table 1). These are consistent to above mentioned studies.
Nayak, et al. [11] reported that several lateral nasal wall pathologies are associated with deviated nasal septum, the commonest and almost consistent being the inferior turbinate hypertrophy, followed by concha bullosa, paradoxical Middle turbinate, polypoidal middle and inferior turbinate [11]. In the present study we found almost similar findings, commonest being inferior turbinate hypertrophy (41.67%) followed by septal spur (33.33%) (Table 2), that is nearly similar with the study of Mirza, et al. and Nayak, et al. [8, 11]. Mahlon, et al. [12] in a retrospective review of 100 patients observed that Endoscopic Septoplasty was performed in 81 patients (81%), FESS was performed in 43 (43%) patients, bilateral inferior turbinoplasty in 15 (15%) patients, partial middle turbinoplasty in 20 (20%) patients. Leena jain, et al. [13] mentioned on the comparative study of conventional and endoscopic Septoplasty, that out of 50 endoscopic Septoplasty, 20 (40%) underwent this in conjunction with FESS. In our study among endoscopic septoplasty group, along with septoplasty functional endoscopic sinus surgery was carried out in 4 patients(13.33%) to clear the pathology (in our series number of FESS was low in number as we intentionally did not advised any patient for computed tomography, so associates sinus pathology if not found preoperatively FESS was not done) partial inferior turbinectomy in 2 patients (6.67%), turbinoplasty was done in 4 cases (13.33%) other surgical procedures are ES with Conchostomy, ES with SMD (Table 2). That is comparable to the study of Mirza Aneesa, et al. Mahlon, et al. and Leena J et al [10,12,13].In our study, post operatively ANS pack given in all patients that was removed on 1st POD in ES group but 2nd POD in CS group. All patients from endoscopic septoplasty group were discharged on 1st POD but in conventional group 25 patients (93.3%) were discharged on 2nd POD. So, it concludes that, there is less hospital stay in endoscopic group in comparison to conventional group. My study is in concurrence with the study of krisna K T [9] and Gupta M [5].
