Abstract
Nasal obstruction is a common complaint in patients with sleep
disordered breathing, occurring in up to 45% of patients. Nasal
airway resistance is responsible for approximately two-thirds of
total airway resistance. Common nasal surgeries performed to
improve nasal breathing and for sleep-disordered breathing include
septoplasty, turbinate reduction, and nasal valve reconstruction.
Septoplasty involves straightening of the nasal septum. The
procedure may be done under local or general anesthesia and a
variety of techniques are used based on surgical training, type, and
position of the septal deviation. Reducing a few millimeters of
anterior septal deviation has been shown to produce significant
improvements in nasal airway resistance.
The aim of this study was to evaluate the outcomes of traditional
septoplasty with or without inferior turbinate reduction in patients
suffering from obstructive sleep apnea due to nasal cause.
In this observational comparative study, the intranasal surgery has a
good effect on the subjective quality of sleep in OSA patients, and
that there might be an added effect on AHI in selected patients with
both septal deviation and hypertrophy of the inferior turbinates.
A total of 60 patients enrolled in this study, their ages ranged from
18 to 52 years old. In both groups, there was a predominance of
males (57% in-group A and 70 % in-group B). Females represent
(43% in-group A and 30% in-group B).
The groups did not differ significantly regarding preoperative AHI,
ODI, ESS, Mallampati score, age, gender or BMI. We looked at
changes in the objective parameters before and after surgery in three
ways: the overall changes in both groups pooled together, changes
within each group, and the changes in the mean difference between
the groups. Overall, in both groups together, there was a significant
reduction in mean AHI after surgery. In comparison, when we
looked at each group separately, we found a significant reduction
in-group A in mean AHI. In group B there was no significant
reduction in mean AHI, ODI or BMI after surgery, but there was a
significant reduction in the mean ESS score.
According to the degree of postoperative changes in the number of
apneas hypopneas per hour of sleep (AHI), patients were divided
into responders and non-responders. Patients who showed 50% or
more reduction in their AHI were considered responders, while
patients who did not reached this level of reduction were considered
non- responders. Cure was defined as reduction of pre-operative
AHI by 50% or more.[91]
In group A: there was 10 patients responders represent 33.3% and
20 patients non-responders represent 66.7% . In group B: there was
six patients responders represent 20% and 24 patients nonresponders
represent 80%
