Abstract

Background: Allergic rhinitis (AR) is characterized by inflammation in the nose as the immune system respond to inhaled allergens in the air. Signs and symptoms include a runny, stuffy red and itchy nose, sneezing with watery eyes, and swelling around the eyes A deviated septum mostly is asymptomatic, but sometimes may be presented by difficulty breathing through the nose, nasal congestion, sinus infections, nosebleeds, sleep apnea, headache, and postnasal drip. Septoplasty is the main surgical intervention for patients with deviated nasal septum to relieve nasal obstruction. While Allergic rhinitis is mainly treated with anti-allergy medicine.

Aim: To detect the incidence of post-septoplasty complications among patients with deviated nasal septum and Identify the correlation between the allergic rhinitis and post-operative complications as compared with non-allergic patients.

Methodology: A retrospective Electronic record-based study was conducted including all patients with clinically diagnosed as deviated nasal septum and undergone surgical intervention at Khamis Mushait General Hospital. Data extracted included patient’s demographic data, recorded post-operative complications and history of having allergic rhinitis.

Results: The study included a total sample of 93 patients; Nasal obstruction was the most frequent complaint among patients. As for post-operative complications, nearly one third of the cases had nasal obstruction followed by external nasal deformity, and smell disturbance. Nasal obstruction was diagnosed higher among patients with allergic rhinitis (P=.142). External nasal deformity was recorded among 6.2% of the cases with allergic rhinitis compared to 3.6% of others without allergic rhinitis. Regarding smell disturbance, it was reported among 13.8% of the patients with allergic rhinitis compared to 3.6% of those without allergic rhinitis.

Conclusions: The study revealed that post-septoplasty nasal obstruction as a complication is most common with similar incidence rate in both allergic and non-allergic rhinitis patient groups while septal hematoma was least common. All post septoplasty complications except nasal obstruction were found to be significantly higher among allergic rhinitis cases.

Introduction

Allergic rhinitis (AR) is a prevalent disease reported among all ages, with the highest percentage in the teenage years [1]. It affects 10–20% of the entire population, hence causing AR to be the one of the most chronic non-communicable disorder [2]. It is mostly under diagnosed or even misdiagnosed, and mistreated, causing harmful health related effects [3]. Allergic rhinitis is characterized by inflammation in the nose as the immune system respond to inhaled allergens in the air [4]. Signs and symptoms include a runny or stuffy red and itchy nose, sneezing with watery eyes, and swelling around the eyes [5]. Symptoms are rapidly emerging with allergen exposure and associated with poor sleep hygiene and work ability [6,7]. Mostly, allergic rhinitis is usually associated with asthma, allergic conjunctivitis, or atopic dermatitis [8,9]. Septoplasty is the main surgical intervention for patients with deviated nasal septum to relieve nasal obstruction [10-14]. In some cases, additional turbinate surgery is performed. Most of studies concerned with post-operative improvement reported that about 60% of patients undergoing septoplasty showed an improvement in nasal breathing [15]. Septal perforation and septal hematoma are recorded as complications along with decreased sense of smell [16]. Temporary hypoesthesia of the front upper teeth after surgery is not rare [17]. The post-operative complications intensity or nature may be affected by whether the patients had allergic rhinitis (AR) or not as AR may aggravates the nasal obstruction and bleeding tendency [18]. The current study is aimed at revealing the incidence of post septoplasty complications among both allergic and non-allergic rhinitis patient groups.

Methodology

A retrospective Electronic record-based study was conducted including all patients with clinically diagnosed nasal septum deviation and underwent surgical intervention (Septoplasty) at Khamis Mushait General Hospital during the period from January 2017 to end of May 2019. Apart from collecting Electronic data the patients were also contacted via telephone to take verbal consent to use their Electronic data and inquire about allergic symptoms if already not mentioned in their record. Patients were excluded if they had missing Electronic files, failure to give verbal consent to participate (Telephonic), failure to contact the patient, or had septoplasty as part of another procedure or along with another surgery. After reviewing the medical files, the data was collected on a pre-structured questionnaire. Data so collected included patient’s demographics and post-operative complications for the surgery such as nasal obstruction, nasal deformity, loss of smell sensation, and others if any.

Data analysis

The collected data was coded, and statistical software IBM SPSS version 22 was used to analyze it. The given graphs were constructed using Microsoft excel software. All statistical analysis was done using two tailed tests and alpha error of 0.05. P value less than or equal to 0.05 was significant. Frequency in percent & distribution of the different collected variables including patient’s demographic data and post-operative complications were analyzed. Crosstabulation was used to show the post-operative complications distribution in relation patients’ history of having allergic rhinitis using exact probability tests.

Results

The study included a total sample of 93 patients out of 120 cases, sixty-five (69.9%) of the patients aged less than 30 years and 60.2% were males. Young aged persons constituted 70.8% of cases with allergic rhinitis compared to 67.9% of cases without. Also, females were 44.6% of cases with allergic rhinitis while 28.6% of those without allergic cases (Table 1). As for post-operative complications, figure 1 demonstrates that 32% of the cases had nasal obstruction followed by external nasal deformity (17%), smell disturbance (11%), dental anesthesia (10%), infection (10%), septal perforation(6%),and nasal bleeding(5%). Considering distribution of the complications according to the patients with history of allergic rhinitis (Table 2), nasal obstruction was diagnosed among 32.3% of the allergic patients compared to 32.1% of cases with no allergic history (P=0.988). External nasal deformity was recorded among 6.2% of the cases with AR compared to 3.6% of others without AR (P=0.613) Septal perforation was recorded among 7.7% of the cases with AR in comparison to 3.6% of the cases without AR (P=0.458). Post-surgical infection with septal abscess was diagnosed among 10.8% of the AR patients compared to 7.1% of the other group (P=0.587). Regarding smell disturbance, it was reported among 13.8% of the patients with AR compared to 3.6% of those without AR (P=0.142). Watery nasal discharge was diagnosed for 4.6% of the patients with AR in comparison to 3.6% of those who were free of AR history (P=0.820). Dental anaesthesia was complained by 12.3% of AR patients compared to 3.6% of others without AR (P=0.191). Lastly, Septal hematoma was recorded one case with AR while was not recorded among any case without history of AR (P=0.509) (Figure 1).

Discussion

High number of deviated nasal septum patients have concurrent allergic rhinitis. Even though the conditions are not similar, for patients with allergies or a deviated septum, there are some similarities. For example, both diseases may lead to sinus infection, both mimic the signs and symptoms of common cold. Allergic rhinitis by the way of triggering allergic response to airborne allergens while deviated septum can also have nasal swelling and increased mucus, leading to same [19,20]. A significant deviated nasal septum causes blockage on one side of the nose and reduces airflow, causing difficulty breathing [21]. On diagnosing nasal septum deviation, medical management using topical nasal steroids, antihistamines, and decongestants as applied for the nasal mucosa is typically attempted first. In case of failure, a surgical intervention to correct the underlying septal deformity is the second line [22-30]. The current study aims to clarify the correlation between the allergic rhinitis and post septoplasty complications as compared with non-allergic patients that will reveal either significant or non- significant impact or difference. The study revealed that nasal obstruction was the most reported post septoplasty complication with close incidence in both allergic rhinitis and non-allergic rhinitis groups [31,32]. This is against what we expected that the postoperative nasal obstruction will be higher in AR patients as a result from AR itself. this observation is supported by another study which was done in our region (South of Saudi Arabia) and found positive outcome of septoplasty for those AR patients with nasal obstruction postoperatively [33]. The second most common postoperative complication is external nasal deformity in both groups, slightly higher among AR patients’ group. The least complication is similar in both groups which is septal hematoma. The other postoperative complications are ordered from more to less common among the patients with AR as following, smell disturbance, dental anaesthesia, infection, perforation, nasal bleeding then watery discharge. While among the patients without AR are infection, nasal bleeding, smell disturbance, dental anaesthesia, perforation then watery discharge which are having the same incidence rate. All post septoplasty surgical complications that were recorded higher among allergic rhinitis cases except nasal obstruction but the higher rate among AR cases was insignificantly different than other for the sample in total.

Conclusion

In conclusion, the study revealed that postoperative nasal obstruction complication is the most one with similar incidence rate in both allergic and non-allergic rhinitis patient groups while the least one is septal hematoma. The other postoperative complications are different in both groups regarding the commonness. All post septoplasty complications except nasal obstruction are slightly higher among allergic rhinitis cases. Our study opens more query and understanding to the pathophysiology of allergic rhinitis and its impact on the post-surgical outcomes.
