Superiorly, the lesion was involving the upper gingivolabial
sulcus which is shown in Figure 1.
The most commonly involved site was mandibular left gingivolabial sulcus (22.
Amongst the snuff dippers mandibular left gingivolabial sulcus (Fig 2), was the most common site of OSCC (22.
The first patient was a 62-year-old woman who presented with vesiculobullous eruptions on her lower lip and adjacent gingivolabial
sulcus, followed by ulceration and crusting of that area for 3 months (figure 1).
During Caldwell-Luc procedure, incision is made 5mm below the gingivolabial
sulcus extending from pyriform aperture medially to the maxillary tuberosity laterally.
Intraorally, there was obliteration of superior gingivolabial
sulcus bilaterally contiguous to maxillary incisors and canines.
2 Disadvantages of this procedure include the obliteration of gingivolabial
sulcus, making it difficult to use prosthesis in future.
1) Remaining extraosseous, they expand into and in front of the piriform aperture, downward into the gingivolabial
sulcus, and laterally into the soft tissue of the face.
A 4 cm incision was made from mid line in the gingivolabial
fold over the convexity of the swelling which was followed by blunt and sharp dissection to free the lesion from the surrounding tissues (fig 3).
A mass can also extend inferiorly into the gingivolabial sulcus or laterally into the facial soft tissue and cause a widening of the nasal vestibule, swelling of the upper lip, obliteration of the nasolabial fold, elevation of the nasal floor, and swelling in the nasal and oral cavity.
with one finger on the floor of the nose and one finger in the gingivolabial sulcus), its precise dimensions are better appreciated by CT.
Incision is usually placed 5 mm above the gingivolabial
