Abstract
The frenum is a normal anatomical landmark in the oral cavity which attaches the lip and the cheek to the alveolar mucosa, gingiva and the underlying periosteum. At times, frenal attachment may pose problems to the health of the gingiva either due to interference in the plaque control or due to a muscle pull and needs to be managed. This case series demonstrates the surgical removal of aberrant frenum using conventional technique of frenectomy.
Highlights
The frenum is a mucous membrane fold that attaches the lip and the cheek to the alveolar mucosa, the gingiva, and the underlying periosteum[1]
Labial frenal attachments are thin folds of mucous membrane with enclosed muscle fibres originating from orbicularis oris muscle of upper lip that attach at the lips to the alveolar mucosa and underlying periosteum[3]
The conventional technique, introduced by Archer (1961)[10] and Kruger (1964)[11], is an excision type frenectomy which includes the interdental tissues and the palatine papilla along with the frenum leading to exposure of underlying alveolar bone[1]
Summary
The frenum is a mucous membrane fold that attaches the lip and the cheek to the alveolar mucosa, the gingiva, and the underlying periosteum[1]. Frenectomy is a complete removal of the frenum, including its attachment to the underlying bone whereas frenotomy involves relocation of the frenal attachment[8]. A similar incision was repeated on the under-surface of the haemostat so that the haemostat gets detached along with the resected portion of frenal tissue within its beaks Once this was achieved, a rhomboid area exposing the fibrous attachment to the bone became visible. A series of three cases (two maxillary and one mandibular) demonstrating the surgical removal of aberrant frenum using conventional technique of frenectomy has been presented (Fig. 1 to 13)
