Purpose: The management of frontal sinus fractures and frontal sinus outflow tract (=FSOT) injuries is controversial. Traditional treatments include frontal sinus obliteration with a variety of material grafts, which all employ complicated algorithms for treatment planning. A simplified algorithm aiming for frontal sinus ventilation, however, can be achieved through the advanced technology of image guided endoscopic surgery and instruments. The authors explain this simplified treatment algorithm of frontal sinus fractures. Methods: The authors reviewed articles on the management of frontal sinus fractures. Results: Complicated treatment planning algorithms of frontal sinus fractures aiming for obliteration were replaced with a simplified algorithm aiming for ventilation of the frontal sinus. Conclusion: The authors suggest that a simplified algorithm can replace the complicated algorithms in selective cases.

A 9-year-old, female Yorkshire terrier and a 10-year-old, female Maltese were referred to the Veterinary Medical Teaching Hospital of Konkuk University. The dogs were presented with severe swelling and cutaneous sinus tract on the left suborbital lesion. Under general anesthesia, we performed physical, intraoral examinations and survey radiography, and diagnosed as periapical abscess in a left fourth premolar tooth. They were treated with tooth extraction, and the sinus tracts were drained with 0.05% chlorhexidine solution. After teeth extractions, medication applied by the result of antibiotic sensitivity test. During follow-up 10 months later, the left suborbital swelling had completely resolved.

Due to their rarity and the lack of associated dental symptoms, odontogenic cutaneous sinus tracts (OCSTs) are often misdiagnosed and confused with cutaneous lesions or non-odontogenic infections. It has been estimated that 50% of individuals affected by OCSTs are subjected to inappropriate treatments before the correct diagnosis is established. We describe the diagnosis and treatment of two cases of OCSTs. By using a computed tomography (CT) with soft tissue window setting, the extent of cortical bone destruction and the path of the sinus tract in the soft tissue was easily identified. Thus, we recommend the use of imaging techniques such as CT, which can confirm the odontogenic origin and the exact location of the OCST.

In Van der Woude syndrome (VWS), a rare congenital disease, lower lip pits (LLPs) can cause an aesthetically significant deformity. Surgical treatment of LLPs is necessary if they cause recurrent inflammation or aesthetic problems. Intraoperatively, surgeons should keep in mind the possibility of deep extension of the sinus tract and the relative deficiency of the midline in VWS, which increases the risk of lip disfigurement. Herein, we emphasize the importance of using a tissue-preserving technique to improve aesthetic results in VWS patients with a sinus tract.

Objectives: To investigate the prevalence of different primary reasons for endodontic referrals and the clinical symptoms of the referred cases. Materials and Methods: Clinical data of total endodontic treatment cases (1,014 teeth) including endodontic referral cases (224 teeth) between January 1, 2010 and December 31, 2012, at Kangdong Sacred Heart Hospital, were investigated retrospectively. The one major reason for referral, the clinical symptoms, and the resulting treatment procedures of referral cases were recorded. The percentages of clinical symptoms of the endodontic referral cases and the total endodontic treatment cases were compared by ${\chi}^2$ test for each symptom. Results: Persistent pain was the most frequent reason for endodontic referral (29.5%), followed by presence of gingival swelling and sinus tract (24.1%), and apical radiolucency (12.9%). Referrals in cases involving endodontic difficulties such as canal calcification, broken instruments, post, perforation, and resorption were less than 5.0%, respectively. The percentages of four major clinical symptoms of pain, apical radiolucency, previous endodontic treatment, and gingival swelling and sinus tract were significantly higher in the endodontic referral cases than those in the total endodontic cases (p = 0.001). Among the included referral cases, 72.8% were treated with nonsurgical endodontic treatment only. Teeth other than the referred teeth were diagnosed as the origin of the problem in 5.8% of the referrals. Conclusions: The high prevalence of pain, apical radiolucency, previous treatment, and gingival swelling and sinus tract in endodontic referral cases suggest that these symptoms may be what general practitioners consider to be difficult and refer to endodontists.

Beta tricalcium phosphate (${\beta}-TCP$) is one of allogenic bone substitute which is known to have interconnected pores that draws cell and nutrients for bone generation. It has been resulted in good outcomes for bone defect coverage or augmentation. However, several studies have also reported negative outcomes and associated complications including unexpected formation of cystic mass, continuous pain and secretion. We present the case of a 36-year-old man with a right cheek cystic mass who had a history of right zygomaticomaxillary (ZM) complex fracture and surgical correction with ${\beta}-TCP$ powder insertion to ZM bone defect. Excisional biopsy under local anesthesia revealed calcified mass in a sinus tract which was found to be connected to the ZM bone defect site in postoperative computed tomography image. Further excision under general anesthesia was performed to remove the sinus tract and fine granules which filled the original defect site. Pathologic report revealed bony spicules and calcification materials with chronic foreign body reaction. Postoperative complications and recurrence were not reported.

The odontogenic cutaneous fistula in facial area is uncommon but, well defined disease. It is difficult to diagnose from the dental origin of cutaneous sinus tract. Most patients may visit to the dermatologists or general hospital without cause of disease. They usually be treated by repeated surgical excisions, biopsies, and antibiotic medications, but suffered from recurrences. We studied odontogenic cutaneous fistula through retrospective study in Jeju Special Self-Governing Province between 1 January 2009 and 12 December 2015. There were 3 males, 5 females from 14 to 78 years old with an average age of 50.4 years old. Only 2 patients felt the toothache, others didn't detect it. They suffered from recurrences and repeated treatments for 3 to 11 months with an average period of 7.9 months. They visited average 2.8 hospitals before a precise diagnosis in a dental clinic. All cases were fully healed endodontic treatment or extraction of origin teeth without recurrences. In conclusion, the cause of cutaneous fistula in facial area can be odontogenic. If dentists or doctors diagnose a patient with cutaneous fistula on face, they should check dental problems or take x-ray views for precise diagnosis. It could be helpful for differential diagnosis.

The pyriform sinus fistula can cause a recurrent abscess in the neck and the current treatment of choice involves complete excision of the sinus tract. But, because of excisional difficult, chemical cautery has been intermittently used as a successful substitute. Recently we experienced a case of pyriform sinus fistula of 9 year-old female who was successfully treated with chemocauterization with trichloroacetic acid(TCA) and ligation of the internal opening of the fistula tract on suspension laryngoscopy. So we report this rate case with review of literatures.
