The Clitoral Infrafrenulum Fascial Bundle: The Anatomy and Histology

Abstract

To determine whether the clitoral infrafrenulum layer exists. This descriptive observational study was conducted using 15 fresh human female cadavers. Macro and micro stratum-by-stratum anatomical dissections of the clitoral frenulum were performed bilaterally. Target tissue biopsies were obtained for microscopic examination and the specimens were stained with eosin and hematoxylin. The skin folds with erectile tissue between them create the superficial stratum of the clitoral frenulum. The inferior edge of the skin fold is firmly fused with the superficial infrafrenulum fascial bundle, which creates the deep stratum. Histological examination confirmed that the clitoral frenulum comprises two layers: 1) the superficial stratum consists of the dermis, sub-dermis with cutis appendages (sebaceous and apocrine glands) and the squamous mucosa with erectile tissue between the skin folds; 2) the infrafrenulum fascia bundle consists of fibro-connective-adipose tissue with intermittent layers of adipose cells and fibrous bands. The clitoral infrafrenulum fascial bundle exists and creates the deep stratum of the clitoral frenulum. Histologically, the clitoral frenulum consists of two layers, the superficial and deep strata. Both strata form the clitoral frenulum stabilizing mechanism. This anatomical discovery has potential for immediate clinical implementation. Clin.

Clitoral frenuloreduction: A new surgical intervention

“…The current intraoperative study verified the anatomical existence of the newly discovered clitoral infrafrenulum fascial bundle (the deep clitoral frenulum stratum) within the clitoral frenulum [1]. This anatomical structure plays an important role in the clitoral anatomical stabilizing mechanism, Figs.…”

“…Recently, Ostrzenski discovered the existence of the clitoral infrafrenulum fascial bundle anatomical structure, which creates the deep layer of the clitoral frenulum [1]. This discovery was incorporated into the current clinical-scientific research in which a new clitoral frenuloreduction surgical intervention was developed.…”

Trilobal Methods for Composite Reduction Labiaplasty

“…The clitoral-labial triangle that contains the clitoral hood, clitoral glans, clitoral frenulum, and superior aspect of the labia minora is an important supporting structure and sex-sensitive area [ 6 , 7 ]. If the triangle is damaged, the natural junction between the clitoris prepuce and the labia minora, which is difficult to repair, will be destroyed.…”

“…1 ). This triangle is an important supporting structure and a sex-sensitive unit located in the midline of the vulva and cannot be destroyed [ 6 ]. Disrupting this anatomical structure during surgery leads to severe complications of the clitoral stabilizing mechanism, including clitoral glans stability [ 7 ].…”
