Incidence of revision adenoidectomy in children.
ABSTRACT Adenoidectomy is a frequently performed procedure in the pediatric population. Revision rates and indications for a second procedure in children are scarce.
Retrospective cohort study.
Patient records at a multistate pediatric healthcare system were searched for all CPT codes that included adenoidectomy in children less than 12 years of age for a 5-year period (2005-2010). A subset of patients was identified for whom the same CPT codes appeared more than once in this 5-year period. The indication, age, gender, adenoid size, and technique of adenoidectomy were recorded.
A total of 23,612 occurrences of the CPT codes were identified. The subset of patients with multiple CPT codes, indicating revision adenoidectomy, included 304 records (1.3%). Mean age at first procedure was 2.8 years (SD = 1.7 years). Mean age at second procedure was 4.7 years (SD = 1.99 years). Mean interval between procedures was 1.8 years (SD = 1.1 years).
Revision adenoidectomy occurs at a rate of 1.3%. Reasons for revision include persistence symptoms ranging from adenoiditis to recurrent otitis to obstructive sleep apnea.

ABSTRACT: To evaluate population-based data on incidence of pediatric adenoidectomy and rate of revision surgery. A retrospective study of all adenoidectomies in children was performed in the year 2009 in all otolaryngology departments in one federal state, Thuringia, in Germany. Patients' characteristics, preoperative diagnostics and postoperative complications were analyzed. The association between baseline characteristics and the risk of re-adenoidectomy was examined using Kaplan-Meier method with univariate log-rank test, and with a multivariate Cox regression model. Population data were used to calculate age-related annual rates of adenoidectomies. 1939 adenoidectomies were performed in 2009 in Thuringia. 89% were primary cases and 11% of the children already had an adenoidectomy prior to 2009. Immediate re-surgery because of primary hemorrhage was necessary in 0.8% of the cases. Re-adenoidectomy because of recurrent symptoms was needed in 9% of patients after a median interval of 16 months. The univariate analysis showed that the factors age ≤3 years and primary surgery were significantly associated to a higher risk of surgery because of recurrent symptoms The multivariate analysis showed that primary surgery was independently associated with the risk of re-surgery (hazard ratio 1.66; 95% confidence interval 1.01-2.74). The annual adenoidectomy rate was 678/100,000 underage habitants. The incidence was highest between 2 and 4 years of age. This population based analysis is showing that adenoidectomy is performed country-wide with good results and low risk on important scale in daily routine by otorhinolaryngologists. The risk of re-adenoidectomy seems to be higher than hitherto reported by hospital-based studies.International journal of pediatric otorhinolaryngology 08/2013; · 0.85 Impact Factor

ABSTRACT: To analyze the prevalence of adenoid regrowth at 1 year after coblation adenoidectomy using cephalometric radiography. Retrospective analysis. One hundred eighty-eight children who underwent adenoidectomy from June 2006 through September 2010 were included. Demographic data, preoperative size of palatine tonsils, presence of allergic rhinitis, concurrent operation of recurrent middle ear effusion, and preoperative and postoperative Korean version of Obstructive Sleep Apnea-18 (KOSA-18) scores were analyzed. The size of the adenoids was measured three times in all the children by lateral cephalometry; preoperatively, at 1 month after adenoidectomy to observe adenoid residual; and at 1 year after surgery to observe adenoid regrowth. The adenoid regrowth at 1 year after adenoidectomy was observed in 25 children (13.3%), and the adenoid residual at 1 month after surgery was observed in 11 children (5.9%) in the cephalometry. Seven of the 11 children with residual disease (63.6%) had adenoid regrowth at 1 year. The regrowth group was significantly younger than no regrowth group, and the preoperative adenoids were larger in regrowth group than in no regrowth group. The symptoms of sleep disordered breathing recurred in two patients and they had revision adenoidectomy. The regrowth rate of the adenoids at 1 year was not low. However, most of the patients were asymptomatic. The adenoid residual at 1 month contributed to regrowth at 1 year, and the risk factors of the adenoid regrowth were younger age and larger initial size of the adenoids. 2b.

ABSTRACT: Adenotonsillectomy is the most common surgery performed for sleep disordered breathing with good outcomes. Children with obesity, craniofacial disorders, and neurologic impairment are at risk for persistent sleep apnea after adenotonsillectomy. Techniques exist to address obstructive lesions of the palate, tongue base, or craniofacial skeleton in children with persistent sleep apnea. Children with obstructive sleep apnea have a higher rate of peri-operative complications.Frontiers in Pediatrics 06/2014; 2:51.

This study examined a large population of children
to determine the rate of revision adenoidectomy.
MATERIALS AND METHODS
After obtaining appropriate institutional review board ap-
proval, the medical records of a multistate, pediatric healthcare
system were searched for occurrences of CPT codes associated
with adenoidectomy in children <12 years of age (42,820 adeno-
tonsillectomy <12 years, 42,830 adenoidectomy <12). The
records were searched over a 5-year period (January 2005–
March 2010). Revision adenoidectomy was defined as two occur-
rences, at separate dates, of an adenoidectomy code for the
same medical record number. This subset of patients was fur-
ther analyzed. Data were extracted from the available operative
notes within the electronic medical record for indications for
procedures, surgical technique used for adenoidectomy, and size
of adenoids. Size was subjectively graded and reported based
upon a numerical scale. An adenoid size of 1þ denotes 0–25%
obstruction of the choanae, 2þ denotes 25–50% obstruction, 3þ
denotes 50–75% obstruction, and 4þ denotes 75–100% obstruc-
tion. There were four separate adenoidectomy techniques used
by surgeons in this study.
There were 23,612 records identified for adenoidec-
tomy or adenotonsillectomy in children less than 12.
Search for second occurrence of CPT code showed 304
records, giving a revision rate of 1.3%. All adenoidecto-
mies were performedat

¼ 1.7 years). Mean age at second procedure was 4.7

dures was 1.8 years (SD ¼ 1.1 years).
The operative reports of 99/304 patients were avail-
able via the electronic medical record for further, detailed
review. Mean size of adenoidal tissue at initial procedure
was 3.5 (SD ¼ 0.59). Mean size of adenoidal tissue at revi-
sion procedure was 1.76 (SD ¼ 0.95) (Table I). Indications
for procedure are listed in Table II). The most common
indications were adenoid hypertrophy (77 vs. 63%), per-
sistent otitis media (42 vs. 20%), and obstructive sleep
apnea (10 vs. 13%).
Technique for initial adenoidectomy was monopolar
electrocautery in 55/99 cases (56%). Microdebrider was
used in 22/99 cases (22%), curette was used in 21/99
cases (21%), and Coblation was used in only 1/99 cases
We have reported a need for revision adenoidectomy
of 1.3% for a large population of children under 12 years
of age. The initial procedure was performed at 2.8 years
of age and the reoccurrence of symptoms were noted by
4.7 years. The causes of regrowth and the indications for
revision surgery appear similar to the indications for the
As a component of Waldeyer’s ring, the adenoid tis-
sue is situated in the nasopharynx and consists of fronds
of lymphoid tissue. Size increases in this tissue during
the first 12 years of childhood is well reported and may
be the result of genetic factors, viruses, bacteria, and
other allergens. The symptoms associated with adenoid
hypertrophy include upper airway obstruction, obstruc-
rhinosinusitis, and chronic otitis media with effusion.
Adenoidectomy is successful for most in relieving these
There are, however, some patients who develop
recurrent or persistent symptoms and seek revision ade-
adenoidectomy is lacking. A 2008 study by Monroy
et al.9of over 13,000 adenoidectomies over an 11 year
period showed a 0.55% revision rate. A 2008 study by
Joshua et al.2on long-term follow-up after adenoidec-
adenoidectomy, but suggested that adenoid regrowth or
persistence may be related to the ‘‘surgical difficulty
encountered by the indirect access to the adenoid pad’’
and adenoid tissue that ‘‘lacks discrete borders.’’ Other
etiologies proposed for recurrence of symptoms after ade-
on rates ofrevision
noidectomy include persistence of tubal tonsil tissue10
Various methods have been employed to perform
adenoidectomy. These range from nonvisualized curet-
tage to endoscope assisted, adenoidectomy. A recent
study11surveyed the practice patterns of 120 pediatric
otolaryngologists and found that the most common tech-
nique was monopolar electrocautery (26%), followed by
curette with cautery touch-up (23%), microdebrider with
cautery touch-up (20%), and Coblation (7%). The authors
also noted an increase in the use of cautery, microde-
brider, and Coblation over the past 15 years and a
decrease in the use of curette techniques. We observed
similar trends; however, the microdebrider technique
was used in a higher percentage of our study population.
Multiple reports are critical of the curette technique
of adenoidectomy. Nonvisualized curette technique with
digital palpation to confirm completeness of adenoid re-
moval reported residual adenoid tissue in 80% of
cases.12Endoscopic evaluation immediately after curet-
tage has shown residual adenoid tissue in >60% of
patients.13Other groups have advocated the use of
transnasal endoscopy and microdebrider to remove re-
Monopolar electrocautery has gained popularity as
a method of adenoidectomy11and is noted to be a pre-
cise, safe method of adenoidectomy, suitable for all ages.
Cautery adenoidectomy reduces operative time and min-
imizes blood loss compared to curettage. Criticisms of
this technique are the introduction of the complications
of neck pain and torticollis associated with cautery sur-
operative time and reduced blood loss as compared to
traditional curette. The disadvantages noted with micro-
debrider is the need for additional equipment and
increased cost.15Additionally, the fixed angle of the
microdebrider blade (19?) and its fixed length may pre-
clude its effective use in older children and adolescents.
Coblation adenoidectomy has gained popularity as
an alternative to electrocautery surgery. This technology
uses dissociation of isotonic saline between two electro-
des to break molecular bonds between tissues. Coblation
allows for tissue dissection at lower temperatures (60
and 70?C) compared to the 400?C of electrosurgery.11

hemorrhage rates comparable to MEC coupled with a
lower incidence of postop dehydration.16Disadvantages
with this technique include need for additional equip-
ment and increased cost.
Whichever method used for the adenoidectomy pro-
surgeons must strive for complete removal of adenoid
tissue from the area of the choanae and the eustachian
tube at initial surgery so as to minimize the risk of
regrowth of adenoid tissue and recurrence of symptoms.
Because the rate of revision adenoidectomy is low, irre-
spective of technique used, a strengths of this study
include the large size of the patient population. The
1.3% revision rate observed in a multistate pediatric
heathcare system with with 15 otolaryngologists forcasts
the number of patients who may require a second opera-
tionon his/her adenoids,
preexisting condition, or comorbid conditions. Limita-
tions of this study include its retrospective design.
Adenoidectomy remains a needed and commonly
performed procedure in children. Regrowth of adenoid
tissue with recurrence of symptoms is rare. We found
the incidence of revision adenoidectomy in children to be
1.3%. Indications for revision are typically recurrence or
persistence of initial presenting symptoms.
