Background: Protruded premaxilla is the most common problem in cases of bilateral clefts causes difficulty in achieving repair in most of the cases as lateral lip elements are not so developed to reach the height of premaxilla leading to significant issues in facial appearance and functions in early childhood. Such premaxilla usually attains an unsightly position after cleft repair. As malpositioned premaxilla is difficult to deal with orthodontic treatment in later childhood, surgical repositioning of premaxilla concomitant to lip repair is much needed in such cases for better aesthetic and functional outcome from early childhood.
Patients and methods: This prospective study was conducted at the Children’s Hospital Lahore from January 2017 to December 2022. A total of 30 patients were enrolled and were dealt with posterior vomerine ostectomy for premaxillary set back. Premaxillary protrusion of more than 10mm was the inclusion criteria. All syndromic patients were excluded from this study. Frequency and percentages were calculated using SPSS 23.0.
Results: Out of 30 patients, 16 (54%) were male and 14 (46 %) were female. Age range was from 3 month to 9 months (mean age 4.6 +1.6 months), Follow up was from 1 - 5 years (mean 2.2+1.07 years). Set back ranged from 8 mm to 20 mm (mean 12.86+1.89 mm). All patients had good aesthetic and functional outcomes assessed by visual analogue scale and scoring system respectively.
Conclusion: Premaxillary setback by posterior vomerine ostectomy is safe option at the time of lip repair for the protruded premaxilla and produces best aesthetic and functional outcome.
