Surgical Correction and Oral Health-Related Quality of Life (OHRQoL) Evaluation of Non-syndromic Congenital Double Lip: A Case Report and Literature Review

Abstract

'Arundeep K Lamba' 'Shruti Tandon' 'Sachin Dhingra'] Congenital double lip is a rare clinical finding that is more common in the upper lip, but the lower lip can also be involved in a few cases. It has no gender predilection, and its incidence rate is yet unknown. It can be classified into two types: congenital or acquired. Congenital type results from the persistence of the sulcus between the pars glabrosa and the pars villosa, while the acquired type occurs secondary to trauma and oral habits such as lip sucking and lip biting. It can be syndromic or non-syndromic based on the other systemic involvement. In the present case, a 24-year-old male patient presented to the outpatient department (OPD) with the chief complaint of an excessive tissue fold visible in relation to his upper lip while smiling and talking, which posed an aesthetic concern to the patient and decreased his self-esteem. The oral health-related quality of life (OHRQoL) was taken before and after the treatment to assess patient satisfaction and improvement in quality of life after surgery. The patient was diagnosed with a non-syndromic congenital double lip based on clinical history and oral examination. The surgical removal of excessive lip tissue was done, and the lesion healed completely with no recurrence up to a six-month follow-up. This case report illustrates the uncomplicated surgical treatment for congenital double lips and improves the patient's aesthetic.
