“…Observed variability in plexus appearance is not attributable to radiation therapy. ABBREVIATIONS: AP ¼ anteroposterior; PCVP ¼ postcricoid venous plexus; PLVP ¼ pharyngolaryngeal venous plexus; PPVP ¼ posterior pharyngeal venous plexus; RT ¼ radiation therapy; SI ¼ superior-inferior L aryngeal and hypopharyngeal venous anatomy has been a subject of interest in the anatomic, [1][2][3][4][5][6][7] otolaryngologic, 8,9 and radiologic [10][11][12][13][14] literature. Anatomists have consistently identified a rich plexus of veins in the postcricoid and posterior hypopharynx, which has been termed the "pharyngolaryngeal venous plexus" (PLVP).…”

BACKGROUND AND PURPOSE: Among patients undergoing serial neck CTs, we have observed variability in the appearance of the pharyngolaryngeal venous plexus, which comprises the postcricoid and posterior pharyngeal venous plexuses. We hypothesize changes in plexus appearance from therapeutic neck irradiation. The purposes of this study are to describe the CT appearance of the pharyngolaryngeal venous plexus among 2 groups undergoing serial neck CTs-patients with radiation therapy-treated laryngeal cancer and patients with medically treated lymphoma-and to assess for changes in plexus appearance attributable to radiation therapy.

“…2 The procedure enables direct visualization of the vocal cords and its related structures, facilitates airway examination without straining, crying or movement, and allows surgeons to rule out synchronous lesions. 15 While this technique offers several advantages, there are some drawbacks that make it less practical as a regular screening or surveillance tool for SGH. First, operative endoscopy does not permit the examiner to assess dynamic laryngeal structures during phonation.…”

Objective: To report our institutional experience in diagnosing and surveilling patients with infantile subglottic hemangioma (SGH) using in-office flexible fiberoptic laryngoscopy (FFL) with video technology, without requiring operative endoscopy in the era of propranolol use. Methods: A retrospective case series was conducted on 4 children diagnosed with SGH between 2016 and 2022 at our institution. Results: Awake FFL with video technology provided adequate visualization of SGH lesions for diagnosis, without any complications. Serial examinations of the airway were performed in the outpatient setting and each SGH gradually regressed, with marked improvement in respiratory symptoms within 48 hours of oral propranolol initiation. Conclusion: Our findings showed that in select patients, FFL with video technology can successfully identify SGH lesions without general anesthesia exposure. FFL may be used as a low-risk screening tool for propranolol therapy initiation in some patients, but operative endoscopy should remain the gold standard procedure for others. By utilizing FFL in this manner, it is possible to diagnose SGH lesions and start propranolol therapy without exposing all patients to the risks of operative endoscopy.
