Abstract

Purpose

The greater palatine artery (GPA) is one of the main vessels supplying the nasal septum. We recently described a novel technique to reconstruct a nasal septal perforation (NSP) using a GPA flap. This radiological study explores the feasibility and limits of using a GPA flap for an anterior NSP repair.

Methods

We describe our technique for repairing anterior-most NSP. Radiological measurements of the GPA flap and their limits were analysed. Additionally, a cohort of four patients who underwent reconstruction of a NSP with a GPA flap was included.

Results

The radiological study of 150 nasal cavities showed a 31.5 ± 2.7 cm2 maximum flap area. Taking into account the retraction process (30%), the remaining area was 22.0 ± 1.9 cm2. The septal area anterior to the GPA was 6.1 ± 2.1 cm2. The septal portion of the flap was larger than the area anterior to the GPA pedicle in all cases. Complete NSP repair was achieved in four patients. All cases of NSP remained closed during the follow-up.

Conclusion

The unilateral GPA pedicled flap is a useful technique suitable for the reconstruction of anterior-most perforations that are difficult to cover with other endonasal techniques.

ePA: Entlastung oder Mehrarbeit?

Die elektronische Patientenakte (ePA) soll das Gesundheitswesen revolutionieren. Mit über 2000 Krankenhäusern und mehr als 100.000 ärztlichen Praxen ist sie eines der größten Digitalisierungsprojekte Europas. Während die Politik die ePA als „Gamechanger“ feiert, zeigt sich in der Praxis ein anderes Bild.

Fast jeder fünfte Tinnituspatient denkt an Suizid

Von Tinnitus Betroffene schweben in erhöhter Suizidgefahr. Dies ist das Ergebnis einer Studie, wonach sowohl Suizidgedanken wie Versuche der Selbsttötung unter Tinnituspatienten häufiger sind.

Langwirksamer Antikörper bremst chronische Rhinosinusitis

Eine subkutane Injektion mit dem Antikörper Depemokimab alle sechs Monate kann die Beschwerden von Menschen mit ausgeprägter chronischer Rhinosinusitis und Nasenpolypen deutlich lindern. Dafür sprechen die Resultate von zwei Phase-3-Studien.

Kopf-Hals-Tumoren: Die Immuntherapie ist kein Selbstläufer

Ergebnisse einer weiteren Studie legen nahe: Mit einer adjuvanten Immuncheckpointhemmung ist lokal fortgeschrittenen Plattenepithelkarzinomen des Kopf-Hals-Bereichs nur schwer beizukommen. Einige Fachleute geben die Hoffnung jedoch nicht auf und diskutieren mögliche Gründe für die negativen Ergebnisse.
