The role of the osteomeatal unit (OMU), or bony channel in the
sinuses, is the main area where infections develop. The OMU can
be blocked by variations in the anatomic structure of the area
or by soft tissue due to inflammation. Exactly what role the anatomic
structural variants play in development of chronic sinusitis is
controversial. These variants, including non-traumatic septal deviation,
typically develop around the time of facial growth during puberty
and completion of paranasal sinus pneumatization (the development
of air cells such as those of the mastoid and ethmoidal bones).
Because of this, you might expect that people who have one or more
of these anatomic variants develop inflammatory paranasal sinus
disease (sinusitis) at an earlier age compared to those who lack
the anatomic variants.
Symptoms and Cause of Paranasal Sinus Disease
Symptoms of inflammatory paranasal sinus disease include facial
pain or pressure, headache, nasal drainage (anterior rhinorrhea
or postnasal drip), nasal obstruction, dysosmia, and/or visual
changes. Because headaches and facial pain can be caused by several
factors, determining the appropriate treatment can be a challenge
to physicians. While a headache can have a cause that is not
paranasal sinus-related it may still can co-exist with, and mutually
impact the inflammatory paranasal sinus disease. The prevalence
of migraine, myofascial pain, cluster headache, and psychiatric
illnesses that can cause or exacerbate facial pain and headache
vary depending upon the age of the patient. For instance, about
90 percent of patients with migraine headache experience their
first migraine before age 40 and the incidence of migraine decreases
after age 40 in both males and females. The presence of one or
more of these illnesses can impact the presenting symptom-complex
of the paranasal sinus disease.
Research Regarding Age and Sinusitis Symptoms
Because of the trend apparent with age in relation to sinus symptoms,
a team from Massachusetts Eye and Ear Infirmary and Harvard Medical
School chose to do a prospective study to determine the age factors.
The purpose of this study, “The Impact of a Patient’s
Age on the Clinical Presenation of Inflammatory Sinus Disease”,
was to determine the impact of the patient’s age on the
symptoms, anatomic findings, co-morbidities, diagnosis, and surgical
outcome of inflammatory paranasal sinus disease. The authors
of the study are Nicolas Y. Busaba MD, Hyeijung Shin MD, and
Salah D. Salman MD, all representing the the Department of Otolaryngology-Head
and Neck Surgery, Massachusetts Eye and Ear Infirmary, and the
Department of Otolaryngology and Laryngology, Harvard Medical
School, Boston, Massachusetts. Dr. Busaba is also affiliated
with the Division of Otolaryngology, VA Boston HealthCare System.
Their findings were presented at the 109th Annual Meeting & OTO
EXPO of the American Academy of Otolaryngology—Head and
Neck Surgery Foundation, on September 25-28, 2005, at the Los
Angeles Convention Center, Los Angeles, CA.
Methodology: This prospective study looked at 514 adult patients
with inflammatory paranasal sinus disease at a single tertiary
care facility. The term inflammatory paranasal sinus disease is
used to encompass CRS, CRS with polyposis, recurrent acute rhinosinusitis,
barosinusitis, mucoceles or mucopyoceles, and antral-choanal polyp.
The patients were grouped off into three groups based on their
age at presentation. Group 1 (n=203) comprised of patients whose
ages were between 18 and 39 years, group 2 (n=213) comprised of
patients whose ages were between 40 and 59 years, and group 3 (n=98)
comprised of patients whose ages were 60 years or older.
The following data were collected: patient demographics (age and
gender), presenting symptoms, co-morbidities (environmental allergy,
asthma, and psychiatric illness), physical examination and nasal
endoscopy findings, computed tomography (CT) findings, diagnosis,
operative findings, and surgical outcome. The presenting symptoms
were facial pain / headache (pressure, pulsating, pricking or stabbing
pain), nasal drainage (anterior rhinorrhea and/or postnasal drip),
nasal congestion / obstruction, and dysosmia. The researchers noted
the following anatomic variants on physical examination and CT:
septal deviation / spur, paradoxical middle turbinate, concha bullosa,
agger nasi cells, and haller cells. Surgical outcome was based
on a questionnaire that was filled by the patients eight weeks
to three months following the operation and that asked about change
in the presenting symptoms: better, same, or worse.
Statistical analysis using chi square test was
performed to determine differences in the incidence of the above
variables
among the three
age groups. Statistical significance was set at a p value of < 0.05.
Results: A total of 514 adult patients (273 women and 241 men)
were evaluated in this study. The mean age was 45.5 years old (range:
18-86 years). Group 1 consisted of 203 patients (112 females and
91 males), group 2 consisted of 213 patients (107 females and 106
males), and group 3 consisted of 98 patients (54 females and 44
males).
Among the presenting symptoms, facial pain and
rhinorrhea (nasal discharge) were most common among group 1 and
least common among
group 3 patients (p < 0.05), while dysosmia (altered sense of
smell) was most common among group 3 patients (p < 0.05). Environmental
allergy, but not asthma, was more prevalent in groups 1 and 2 compared
to group 3 (p < 0.05). There was no statistically significant
difference in the prevalence of psychiatric illness among the three
groups. Anatomic abnormalities combined (septal deviation, paradoxical
middle turbinate, concha bullosa, haller cell, agger nasi cell)
were more common in groups 1 and 2 compared to group 3 (p < 0.05).
Chronic rhinosinusitis (CRS) without polyposis was the most common
diagnosis in group 1 and CRS with polyposis was the most common
diagnosis in groups 2 and 3 (p < 0.05). There was no difference
in the relative prevalence of antral-choanal polyp, barosinusitis
and mucocele among the groups. The vast majority of the patients
in the study and in all age groups reported improvement in all
the presenting symptoms following surgery. However, group 3 patients
reported more improvement in nasal drainage following endoscopic
sinus surgery (p<0.05), while group 1 patients reported higher
rate of improvement in olfactory function (p < 0.05). There
was no statistically significant difference in the improvement
of other presenting symptoms including facial pain among the groups.
Conclusions: The clinical presentation of inflammatory paranasal
sinus disease varies with age. The younger patients are more likely
to complain of facial pain or headache, have allergic rhinitis,
and have anatomic obstruction of the OMU. The older patients report
more dysosmia on presentation and are more likely to have nasal
polyposis. The vast majority of the patients in the study and in
all age groups reported improvement in all the presenting symptoms
following surgery; however, olfactory function is more likely to
improve in the younger patients, while nasal drainage is more likely
to improve in the older patients.
