Interlabial fusion: As a new subtype of labial fusion

Aim: to determine a new subtype of the labial fusion and to arrange treatment options according to this type.Material and Methods: We reviewed the medical records of patients with labial fusion, malodorous vaginal discharge and vulvarpruritus from July 2016 and August 2018 in pediatric surgery outpatient clinic. Anomalous fusion between labia minora and labiamajora was observed in some patients, especially with vaginal discharge and pruritus. These patients were separated, characterizedby common features and identified as a new subtype.Definition and Nomenclature: In this subtype, fusion is between the labia minora and majora, bilaterally. As the fusion is between thelabia minora and labia majora, we prefer naming this condition as Interlabial ( inter. lat=between) Fusion.Results: A total of 86 patients were included. Of this 86 patients 6 were admitted due to malodorous vaginal discharge and vulvarpruritus. Four of the six patients had abnormal adhesions between the labias. These patients were defined as interlabial fusion.Interlabial fusion was detected in only 4.7% of the patients. Topical steroid therapy was started in each of the four patients. All of thepatients were fully recovered.Conclusion: Interlabial fusion is a rare condition, but it is not a separate disease. It is the result of different diseases affecting thegenital area. It should be brought to mind in patients presenting with complaints of vaginal discharge and pruritus, especially if thesecomplaints have recurred. Topical steroid therapy should be started as an initial treatment.
