Purpose
To study the incidence of sialocele formation in the parotid gland and to study the incidence of facial nerve affliction following treatment of mandibular condylar and sub-condylar fractures.
Materials and methods
The present study is a retrospective study conducted on a total of 82 patients with 107 sub-condylar and condylar fractures treated in this centre from August 2008 to August 2020. The surgical approaches used to treat the fractures were considered, and the occurrence of sialocele, salivary fistula and facial nerve paralysis was noted. The facial nerve function was analysed using House–Brackmann system of classification.
Results
The incidence of sialocele formation was seen in 15.87% of cases, and the incidence was seen more commonly during a preauricular approach (52.94%) followed by retromandibular (41.17%) followed by anterior parotid transmassetric approach (11.76%). The incidence of facial nerve affliction was seen in 17.57% of cases with majority of them showing temporal branch involvement in 21.05% of cases.
Conclusion
During the treatment of condylar and sub-condylar fractures, the facial nerve is at considerable risk of damage; however, understanding the anatomy of the nerve is of importance to avoid such complications. Sialocele formation is also an undesirable complication of such surgeries, a prompt diagnosis and early treatment is mandatory to overcome further unwanted sequel.
