In this case, an extraoral sinus tract
of odontogenic origin was observed.
All patients were treated under general anesthesia with surgical excision of the sinus tract
through a neck incision.
Histopathological examination of sinus tract
under the magnification of 20 showing the presence of granuloma with no central caseation (arrow)
Results showed that there was over prescription of antibiotics for pulpitis, sinus tract
infections and severe gingivitis, which may be treated by clinical therapy alone.
"Once you have sinus tracts
it's critical to remove them."
The primary aim of any surgical approach is the complete excision of the sinus tract
along with potential for rapid healing, lesser morbidity, lesser potential for complications and enhanced long-term results in terms of lower recurrence rates.
Another study examining HS lesions at the time of surgery revealed biofilm formation of sinus tracts
, further suggesting biofilms may play a role in the pathogenesis of HS (23).

associated with a mandibular second molar having a rare distolingual root: a case report," Head and Face Medicine, vol.
Fibrous growth in the gingiva exhibits opening of a sinus tract
(arrows) surrounded by an abscess.
The classic histopathology findings included the following: (1) a skin tag: stratified squamous epithelium with occasionally striated muscles or cartilage; (2) a main lesion: stratified squamous epithelium with surface parakeratosis and absence of dermal adnexal structures, with mild inflammatory infiltrate of lymphocytes, plasma cells, and neutrophils possibly present; and (3) a sinus tract
: squamous or pseudostratified columnar epithelium.
Progression of infection may lead to prosthetic loosening, muscle/soft tissue abscess, and eventually the development of a draining sinus tract
Magnetic resonance imaging performed without contrast demonstrated a 2.2 x 6.5 x 2.1 cm intraosseous abscess contiguous with the sinus tract
communicating with the skin.
