ABSTRACT
BACKGROUND: Pharyngocutaneous fistula is a troublesome complication. Recently, synthetic materials such as fibrin sealant have been used as a secondary measure to treat fistula. This work assessed whether the primary use of fibrin sealant can reduce the rate of fistula. METHOD: A retrospective review of 50 cases from 2 centres was completed. Tisseel was an adjunct to primary closure in all cases. RESULTS: In the first centre, 3 out of 34 cases developed pharyngocutaneous fistula (fistula rate of 9 per cent). All three were salvage cases. In the second centre, 0 out of 16 cases developed a fistula. CONCLUSION: The incidence of pharyngocutaneous fistula post-radiation and post-chemoradiotherapy in laryngectomy cases has been quoted as 23 per cent and 34 per cent respectively. This study represents the first patient series on the use of fibrin sealant as an adjunct in primary closure following laryngectomy. The results are promising, encouraging the use of Tisseel as an adjunct to meticulous closure.

OBJECTIVES: Bifid mandibular condyle (BMC) with associated temporomandibular joint ankylosis (TMJA) is extremely rare with only four cases reported. We present the first case series of BMC with TMJA in an attempt to elucidate the morphological pattern in this rare condition. METHODS: Retrospective examination of CTs over a period of 6 years revealed 37 patients with TMJA, of whom 10 had BMC. Clinical and CT features of these were analysed. Patients were grouped according to sides of involvement and orientation of condyles. RESULTS: The male:female ratio was 1:1. Nine were post-traumatic and one post-infectious. The aetiology was sustained in childhood in all patients. Six patients had unilateral BMCs and four had bilateral. One patient had bilateral BMCs with bilateral TMJA. This was anteroposterior (AP) in orientation. Three patients had bilateral BMCs with unilateral TMJA, among which one was AP and two mediolateral (ML). Six patients had unilateral BMC with ipsilateral TMJA; all of the ML anterior condylar process was ankylosed in joints with AP BMC and TMJA. Lateral condylar process was ankylosed in post-traumatic ML BMC with TMJA, while the medial condylar process ankylosed in the post-infectious patient. In general, ankylosed heads were found to be larger, sclerotic and often mushroom shaped compared with non-ankylosed heads. CONCLUSIONS: This series attempts to elucidate patterns of ankylosis and CT morphology in BMC with associated TMJA. Also included are hitherto unreported cases such as bilateral AP BMC with TMJA and post-infectious BMC with TMJA.

Pneumorrhachis (air in the spinal canal) is an uncommon radiological finding. Its detection in gangrenous abdominal emergencies is rarer with uncertain prognostic significance. We illustrate the computed tomography features and assess the patient outcomes in two cases of pneumorrhachis identified in gangrenous pathologies of the abdomen (emphysematous pyelonephritis and bowel gangrene). Patient outcome was poor in the current and previously reported cases. Pneumorrhachis could be an additional imaging sign of poor prognosis in acute gangrenous abdominal emergencies.
