The role of ipsilateral tonsillectomy in the extirpation of branchial
cleft anomalies- A retrospective monocentric analysis over 13 years
Introduction. Branchial cleft anomalies (BCA) can occur as sinuses,
fistulas or cysts. They arise from the first, second, third or fourth
pharyngeal cleft due to non-fusion or subinvolution. Mostly, located in
Robbin’s neck-level II, BCA clinically present as a painless
compressible swelling, cutaneous draining sinus, or fistula. Surgical
treatment is the gold standard to prevent recurrence, though the
necessity of ipsilateral tonsillectomy is discussed. Study Design. We
conducted a retrospective comparative cohort study. Setting.
Monocentric. Methods. In retrospect, data was collected from patients,
that were admitted with the diagnosis BCA between 2006 and 2020 in an
academic tertiary care center. Main outcome measures. 160 patients met
inclusion criteria, the data was further evaluated, the focus was set on
the occurrence of recurrence with or without tonsillectomy. Results.
Recurrence of BCA was observed in 2 out of 160 surgically treated
patients (1,25%), one of them with simultaneous tonsillectomy, the
other without. Conclusion. A statistically significant difference in the
recurrence-rate between these two groups (with/without tonsillectomy)
could not be shown. The performance of an ipsilateral simultaneous
tonsillectomy in the surgical workup of BCA cannot be recommended at the
basis of our data.
