Background: Endoscopic septoplasty is a minimally invasive surgical procedure for the correction of nasal septal deformity. Globally, nasal septal surgeries are rarely performed, and in our country these procedures are even more scarcely undertaken, partly due to dearth of facilities and to some extent, the expertise of embarking on this specialised surgical procedure. Therefore, we aimed to document the indications and the outcome of endoscopic septoplasty in our environment. Materials and Methods: This was a retrospective study of all consecutive patients that had endoscopic septoplasty at a state tertiary hospital over three years period. Ethical approval was obtained before commencement of the study. Patients’ medical records were retrieved. Biodata, clinical presentation, operative procedure and outcome were extracted and analyzed descriptively. Results: Fourteen patients had endoscopic septoplasty over the period under review, constituting 11 (78.6%) males and 3 (21.4%) females. Predominant clinical features were nasal obstruction (100%) and nasal septal deviation (100%). The main indication for procedure was deviated nasal septum. The outcome of the surgery was good, 2(14.3%) of the patients had nasal adhesions but no major complication was recorded. The length of hospital stay ranged between 3 and 5 days with a mean of 3.7 ± 0.9 days, and all the patients were discharged successfully. Conclusions: Endoscopic septoplasty is a safe surgery. The main indication for the procedure was deviated nasal septum, and the procedure has a favourable outcome among the operated patients.

| Introduction|| |
Endoscopic septoplasty is a minimally invasive surgical procedure performed for the correction of nasal septal deformity. It is mostly performed for patients with deviated nasal septum (DNS), which is one of the commonest causes of nasal obstruction in rhinology practice. DNS if not corrected can result in atypical facial pains, contact point headaches, difficulty in breathing, epistaxis, and may predispose to chronic rhinosinusitis (CRS)., Nasal septal surgery generally improve the quality of life of the patients, and it is an acceptable surgical procedure based on documented outcome studies globally. It is worthy of note that not all patients that underwent endoscopic septoplasty become totally free of symptoms., Some of the patients do well with adjuvant medical treatment as well as revision surgery.,
Septoplasty has been traditionally performed under direct visualisation with headlight illumination. However, the direct visualisation (open) approach has been associated with more complications compared with endoscopic method. Other disadvantage of open septoplasty include poor visualisation and illumination which may lead to difficulty in accessing the pathology (especially posterior part of the septum), unnecessary manipulation, and overexposure of the septal framework thereby reducing the scope for a revision surgery. On the contrary, the endoscopic septoplasty is now gaining more popularity due to its precision in identification and excision of septal and lateral nasal wall pathologies, thereby reducing morbidity and complications.,
Globally, nasal septal surgeries are rare even in the developed countries, with approximately 250,000 operations performed annually in the United States and an estimated 22,000 surgeries performed in the United Kingdom. However, in the third-world countries like Nigeria, the septal surgery is even more scarcely performed, partly due to dearth of facilities and to some extent, the expertise of embarking on this highly specialised surgery, not because of unavailability of patients that need the procedure. Furthermore, at the time of writing this article the authors have not found local report of endoscopic septoplasty in the literature. Therefore, in this study we aimed to present the indications as well as the outcome of endoscopic septoplasty among patients who presented at our institution during the study period.
| Patients and Methods|| |
This was a retrospective study of all consecutive patients that had endoscopic septoplasty at our institution from 2018 to 2021. Ethical approval for the study was obtained from the research and ethic committee of the hospital. Case files of the patients were reviewed and information on demography, clinical history, examination findings, investigations as well as operative procedure were extracted. Paranasal sinus computed tomography (CT) scan of the patients were retrieved and studied. All patients had preliminary complete blood count, renal function test, and were found to be normal. Consent for surgery was obtained and patients fasted for at least 8 h before the surgery. All the reviewed patients had surgery done by the same Surgeon under general anaesthesia, intubated with an appropriate size endotracheal tube. Nasal preparation was done with pledgets soaked in diluted adrenaline 1:200,000 to decongest the nose. A preliminary nasal endoscopy was carried out on all the patients with a zero-degree telescope. Local infiltration was performed at the muco-cutaneous junction of the nose to elevate the muco-perichondrion and the muco-periosteal layers of the nasal septum. An incision was then made at the Cottle’s area, muco-perichondrial flap was then raised up to the bony–cartilaginous border, and septoplasty was then performed. The extracted information was entered into a Proforma and thereafter in to a Statistical Product and Service Solutions (SPSS) version 23.0 software. The data was then analyzed and the results were presented as prose and tables.
| Results|| |
A total of 14 patients underwent the surgery for the period under review. The age of the participants ranged between 11 and 50 years with mean (and standard deviation) of 34.1 ± 11.1 years. There were 11 (78.6%) males and 3 (21.4%) females [Table 1]. [Table 2] shows distribution of clinical features. All the patients presented with nasal obstruction and septal deviation, and significant number presented with nasal discharge (78.6%), sneezing (64.3%), engorged inferior turbinates (64.3%) and nasal polyps (35.7%). All the patients have done CT scan and the findings have been shown in [Table 3]. A representative CT scan of a patient with septal deviation is shown in [Figure 1]. The main indication for septoplasty in these patients was DNS with or without polyps, and most of them, 13(92.9%) had endoscopic assisted septoplasty with endoscopic sinus surgery for definitive treatment. Intraoperative images are shown in [Figure 2]A and [Figure 2]B. The outcome of the surgery characterised by relief from nasal obstruction was good, no major complication was recorded, and all the patients were discharged successfully. Two (14.3%) of the patients had adhesion between the septum and inferior turbinate, adhesiolysis was done under local anaesthesia, and no repeat surgery was performed. The length of hospital stay ranged between 3 to 5 days with mean and standard deviation of 3.7 ± 0.9 days. Histological diagnoses after surgery revealed benign histology with majority of the patients having chronic rhinosinusitis with inflammatory polyps 10(71.5%) [Table 4].

Endoscopic septal surgeries are usually challenging especially in resource constrained settings like ours. Despite the challenges of dearth of equipment and instruments necessary to embark upon these procedures in most hospitals in the country, our health facility have done a few of this procedure within the period under review. In this study, male preponderance was noted, and DNS was found to be more common in patients above 30 years. This is similar to the findings of Moshfeghi et al. in Iran, where they documented that males had higher prevalence of nasal septal deviation and it was found to be increasing with advancing age, hence older men tend to have more nasal septal surgeries than their female counterpart. Similarly, other studies conducted among patient with septal deviation also documented male preponderance.,
The commonest symptoms of our patients were nasal obstruction, nasal discharge and sneezing. This is because most of the patients had background chronic rhinosinusitis (CRS), and these symptoms were also the commonest manifestation of CRS in our environment.On examination, all the patients we studied had septal deviation, engorged inferior turbinate or nasal polyps in addition to background CRS. This is similar to the findings of other studies in our environment where septal deviation and engorged/hypertrophied inferior turbinates constituted significant findings in patients with CRS.,,, Similarly, a study conducted elsewhere reported that all patients with nasal septal deformities had other associated nasal or paranasal sinus pathology (i.e., CRS or nasal polyps).
CT scan was the adopted investigative tool for this study, it was employed in the assessment of all the patients before embarking on surgery. This investigative modality is the most preferred imaging modality that precisely shows paranasalsinus anatomical variations (e.g., septal deviation) and it is very useful in planning for endoscopic sinus surgery as well as endoscopic septoplasty. The main indication for septoplasty in our series was DNS. Septal deviation was reported to be the commonest indication for septoplasty. Other indications include contact point headache, provision of better access during endoscopic sinus surgery, and a source of graft or flap during endoscopic skull base surgery., Most of patients in this study had endoscopic septoplasty together with endoscopic sinus surgery. This is similar to a study conducted in Jordan where they reported that majority of the cases of septoplasty were performed in conjunction with endoscopic sinus surgery. Furthermore, Chung et al. reported that concomitant procedures performed with endoscopic septoplasty included endoscopic sinus surgery (81.9%), turbinate reduction (44.8%), and rhinoplasty (4.3%). However, in another study septoplasty was performed concomitantly with endoscopic dacrocystorhinostomy.
In this series, the outcome of endoscopic septoplasty was good, no major complication was recorded, and only two (14.3%) patients had adhesion, which was managed successfully. This is similar to the findings of Nawaiseh and Al-Khtouum where they reported two (14.3%) minor complications(septal hematoma and haemorrhage), and no major complication was recorded. However, Chung et al. reported several complications including; transient dental pain/hypoesthesia in 5 patients, asymptomatic septal perforation in 4 patients, synaechia formation in three patients, and epistaxis and septal hematoma in one patient each. The low frequency of complications in our study may be due to small number of patients included in to the study or retrospective nature of the study. Therefore, the good outcome of endoscopic septoplasty recorded in this study need further validation. Hence, we recommend a prospective multicenter study that will employ large sample size in order to make a more statistically significant conclusion on the outcome.
| Conclusion|| |
Deviated nasal septum remained the main indication for endoscopic septoplasty in this series. The procedure is relatively safe and it has a good outcome among the operated patients. However, patient selection, appropriate operative equipments and the necessary surgical expertise are key in maintaining a favourable outcome.
