Pyriform sinus fistula (PSF), constituting <2% of branchial cleft anomalies (1), is a congenital entity due to abnormal development of the third or fourth branchial cleft (2). Anatomically, PSF begins at the pyriform fossa, penetrates the cricothyroid muscle, and terminates laterally in the thyroid gland (3, 4).

Pyriform sinus fistula (PSF) is a rare congenital entity. We hypothesized that clinical features, diagnosis and treatment may differ between newborns and children. 190 patients diagnosed with PSF were divided into two groups: neonatal (n = 15) and childhood (n = 175).

Pyriform sinus cyst (PSC) and pyriform sinus fistula (PSF) is a rare congenital malformation that arises from the third or fourth branchial structure. In our study, we describe the safety and the utility of endoscopic electrocauterization against PSC/PSF.

Pyriform sinus fistula (PSF), which originates from the failure obliteration of the third or fourth pharyngeal pouches, is rare and often overlooked [1–3]. Misdiagnosis exposes the patients to the risk of repeated infection and inadequate management.

Background: Congenital pyriform sinus fistula (CPSF) is a rare congenital disease derived from the remnants of the third or fourth branchial cleft. Objectives: To investigate the imaging characteristics, clinical manifestations, surgical methods, complications, and personalized treatment of CPSF.

2019年12月6日 · Pyriform sinus fistula (PSF) is a rare congenital entity. We hypothesized that clinical features, diagnosis and treatment may differ between newborns and children. 190 patients diagnosed with PSF were divided into two groups: neonatal (n = 15) and childhood (n = 175).

2019年11月1日 · Congenital pyriform sinus fistula (CPSF) is a branchial abnormality originating from the third or fourth branchial pouch and is an important cause of anterior cervical abscess in children. Here we present a case of neck abscess in a newborn that was diagnosed as CPSF.

Herein we describe a case of bilateral piriform sinus fistulas, and present a review of the literature concerning their endoscopic management. Our patient was determined to have bilateral piriform sinus fistulas based on computer tomography, magnetic resonance imaging and microlaryngoscopy.

2016年4月6日 · Pyriform sinus fistula is the rarest of the cervical branchial anomalies. A recurrent left sided lower neck infection may be the only clue to this elusive entity.
