Background: Over the years, an optimal surgical method for septorhinoplasty in deviated nose as a challenging problem was the one of common interest of plastic surgeon; the purpose of this study is to compare outcomes of open and closed methods of septorhinoplasty in patients with deviated noses. Methods: Through a prospective study, we selected seventy patients with deviated nose. Based on their deviation severity, they underwent open or closed septorhinoplasty. Patients were evaluated for deviation angles of nasal bony and cartilage components, nasal projection, nasolabial angle, nasofacial angle, and nasofrontal angle; for which three standard photos were captured pre and postoperatively. Finally the outcomes were analyzed according to their surgical methods. Results: Closed septorhinoplasty could grant a mean 11 degrees correction to nasal bony component and a mean 8.6 degrees correction to cartilage component. That’s while open septorhinoplasty could bring a mean 19.5 degrees deviation correction to the bony component and a mean 12.5 degrees deviation correction to the cartilage component. Cosmetic angles were not improved significantly after the surgery, maybe because of complicated deformities our series of patients had. Conclusion: Open septorhinoplasty resulted in better cosmetic and functional outcomes than the closed method.
Nasal deviation, termed as “deviated nose” in medical literature, is a complex deformity involving almost all structures within the nose [1,2]. Deviated nose or crooked nose can be defined by drawing a line virtually drawn from mid-glabella to pogonion (glabella-to-pogonion line), passes through nasal bridge, nasal tip, and cupids’ bow and finally incisive teeth; nasal deviation from this line to either side, would be defined as “deviated nose” [2-4].
Anatomically, nasal deviation may be categorized into the following deformities: “tilt deformity”, “S-shaped deformity”, and “C-shaped deformity” or a combination of them [
Etiologically, deviated nose is almost always caused by nasal trauma; although many of those deformities without known causing trauma are incorrectly referred to as congenital or evolutional deformities; it’s now believed that even those deviations too, are caused by tiny fractures during intrauterine life, obstetric traumas, or traumas in infancy and early childhood. Whatever the cause of deviated nose is, this deformity precipitates in structural asymmetry leading to a variety of problems to either or both nasal aesthetic and function [
Surgeons might be so obsessive about the cosmetic outcome, because this is maybe the only thing that satisfies their patients best; but sometimes patients favor a better functional outcome than the aesthetic; the truth is that both aesthetic and function have their own values, one gives a better self-image and one gives a better quality of life, so the effort should be put on the selection of a surgical method which best fulfills the ideals for both aesthetic and function. Certainly, they are not easily achievable, and keeping both at their optimums is the art of a good surgeon. Thus, septorhinoplasty in patients with deviated nose, more as a therapeutic operation than a cosmetic, should pay attention to nasal function as much as nasal aesthetic [9-11].
There are a variety of surgical techniques for septorhinoplasty, and no unique method is applicable to all patients [10,12-15]; it’s on the surgeon to choose the best that ends up to a better possible outcome. This study aims to investigate the outcomes of open and closed septorhinoplasty in patients with deviated nose and the way each affect on nasal cosmetics and function.
We designed a prospective study in which 70 patients with “deviated nose” entered. The patients were selected among those referred to ENT-clinic of a tertiary healthcare center (Imam Khomeini Hospital, an affiliate of Tehran University of Medical Sciences). They were all indicated candidates for septorhinoplasty with obvious external nasal deviation. Both cosmetic and functional problems were present in approximately all these patients. Operation method was chosen upon deviation severity. Patients with mild to moderate deviations underwent closed septorhinoplasty and those with moderate to severe deviations had open septorhinoplasty. The study started in 2007 and finished in 2011.
Patients with deviated nose, who were selected for septorhinoplasty and had followed up at least 12 months after their surgery, were entered to the study.
None of our patients suffered from systemic diseases such as sarcoidosis or Wegner granulomatosis and psychological problems.
Moreover, pregnant patients, patients younger than 18 years, immunedeficient patients, and cases with malignancy were excluded from this study.
Accordingly, revision cases were disqualified.
The protocol of this study was approved by the Institutional Review Board of the Tehran University of Medical Science. Detailed information about the study was given to the participants and a written informed consent was obtained from each one. All aspects of the study were conducted according to the Declaration of Helsinki.
Pre-op evaluations: A questionnaire consisting of two parts of pre-op and post-op data was made; patients filled out their demographic data and their chief complaints. They also graded their pre-op symptoms’ severity as mild, moderate or severe. A complete physical examination was performed by a physician in-charge, and positive findings were reflected into the sheets.
Deviation angles of bony and cartilage components: Three standard photos (a full-view, a side-view and a nasal base-view) were captured once before the surgery and once after, at follow-ups. The values required for deviation measurements were obtained from the photos through computer analysis. This was based on the “light reflex” as a quantitative measure for nasal deviation. Usually, the light reflex on a plane dorsum of a non-deviant nose is a straight and non-angled line; but in deviated noses, the light reflex makes an angle with glabella-to-pogonion line; this was considered as deviation angle. By putting these pre and post-op values into comparison, the relative deviation correction angle would be defined. The values were measured for both bony and cartilage components distinctly.
According to computer analysis, noses with 0˚ deviation were considered as perfect, whereas 0˚ - 10˚ were treated as mild deviation, 10˚ - 20˚ as intermediate, and 20˚ - 30˚ as severe.
Photographs were taken with a Canon power shot S5 digital camera with a Canon X12 Zoom lens to ensure proper and uniform photographic size. We used the same position of patients and photographer, according to the Frankfort horizontal line at a fixed distance of 1 m. The facial section between the horizontal planes running above the eyebrows and below the mentum was copied from the postoperative photograph.
Aesthetic indexes were measured using Adobe Photoshop 7 software which provided an accurate analysis of the same facial sections in the preoperative and postoperative photographs [
Nasal projection: according to Goode’s method, nasal projection is a proportion, defined as the length of alar point-to-nasal tip line divided by the length of the nasion-to-nasal tip line. The normal value for this proportion is 0.55 to 0.60.
Nasolabial angle: is the angle defined by subnasale-to-labrale superius line intercepting with columellar point-to-subnasale line. Its normal range is within 90˚ - 100˚ for men and 100˚ - 110˚ for women.
Nasofacial angle: is the angle made by nasion-to-tip line and glabella-to-pogonion line. The ideal for this angle is 36˚, although 30˚ - 40˚ is an acceptable range.
Nasofrontal angle: is simply the angle defined by nasion-to-glabella line intersecting with nasion-to-tip line. Normal range for this angle is within 115˚ - 130˚ [
Patients’ satisfaction rates: postoperatively at the end of evaluation, patients were asked to determine their satisfaction rates with their cosmetic and functional outcomes, separately; for each outcome they chose one of the following options: 1) fully satisfied with the outcome; 2) relatively satisfied with the outcome; 3) Just satisfied with the outcome; 4) relatively unsatisfied with the outcome; and 5) fully unsatisfied with the outcome.
Septorhinoplasty was performed in either open or closed methods. Putting the patients into these groups was based on their deviation severity; patients with mild to moderate deviation, especially in bony parts would undergo closed septorhinoplasty, while those with moderate to severe deviation would have open surgeries. Accordingly, if patients needed spreader grafts for correction of dorsum and valve problems, the open approach would be chosen.
All procedures were performed by one of the senior authors under general anesthesia. Additionally, internal lateral osteotomy was performed in all procedures. No
packing was used. Moreover, antibiotic prophylaxis (Cephalexin 500 mg/QID for five days) was given to all patients and the only prescribed analgesic was acetaminophen. Subsequently, their nasal splints were removed after 21 days but tapings were continued for 4 weeks thereafter.
In both groups, the correction of deviate septum was performed primarily by using of all techniques. Also, in severely deviated septum extra-corporeal septoplasty was conducted. Additionally, columellar strut was use in all cases. Accordingly, in all open cases bilateral spreader grafts were used.
In addition to demographic data and satisfaction degrees rated by patients in follow-up visits, other effective cosmetic factors were extracted from photos analyzed by computer, to determine the interrelationship of surgical method with the cosmetic and functional outcomes. These factors were pre and post-op deviation angles of nasal bony and cartilage components, nasal projection, nasolabial angle, nasofacial angle, and nasofrontal angle. Data were analyzed by t-Test and Wilcoxon Signed Ranks Test, using SPSS (11.5). P values less than 0.05 were considered as significant.
Among 70 patients, completed our post-op survey; from which, 40 (57.1%) had undergone closed septorhinoplasty and the rest 30 (42.9%) had open surgeries.
We had 56 (80%) male patients and 24 (20%) females. The average age was 23.3 ± 4.5 years, ranging from 18 to 36. 57 patients (81.4%) reported previous trauma to their noses, while the rest could not specify a cause.
The average follow-up period was 14.2 ± 4.3 months with a minimum of 12 and a maximum of 24.
In patients’ own point of view, chief complaints included nasal obstructive symptoms in 50 patients (71.4%) and cosmetic problem with nasal deviation in 16 (22.9%). Only one patient had symptoms related to chronic sinusitis, such as purulent post-nasal drip, severe nasal congestion and facial fullness.
45 patients (64%) graded their pre-op symptoms as severe, 14 (20%) as moderate and 11 (16%) as mild.
Deviation correction of bony and cartilage components of the nose were measured by light reflex, and patients’ data was analyzed in groups according to surgical method.
The mean value for pre-op bony component deviation angle was 17.4 ± 6 degrees, which was postoperatively reduced to 6.4 ± 5 degrees (t-Test, P = 0.0001). Closed method also could reduce cartilage component deviation angle from 16.5 ± 6.3 degrees to 8 ± 6.2 degrees (t-Test, P = 0.099).
In this group, pre-op mean deviation angle of bony component was 25 ± 3.7 degrees, while the same value was plummeted to 5.4 ± 5 degrees after the surgery (t-Test, P = 0.0001). Of cartilage component, a mean 18 ± 5.5 degrees pre-op deviation angle had cut to 5.3 ± 3 degrees, postoperatively (t-Test, P = 0.044).
Closed septorhinoplasty could grant a mean 11 ± 7 degrees correction to nasal bony component (t-Test, P = 0.004) and a mean 8.6 ± 6.5 degrees correction to cartilage component (t-Test, P = 0.0001). That’s while open septorhinoplasty resulted in a mean 19.5 ± 6 degrees deviation correction to the bony component (t-Test, P = 0.005) and a mean 12.5 ± 4.3 degrees deviation correction to the cartilage component (t-Test, P = 0.0001).
