摘要

Background

Tension-free closure of the nasal lining is possible in all clefts provided that the nasal mucosa is appropriately released. This study aimed to evaluate how releasing the nasal mucosa, along with the transverse fibers of the levator veli palatini and the longitudinal fibers of the musculus uvulae from the posterior nasal spine, affects palatal lengthening during unilateral cleft palate repair.

Methods

This prospective, randomized clinical trial was conducted on 60 patients with cleft palate (Veau types 2 and 3). The patients were divided into two equal groups at random: the first group underwent radical release of the nasal mucosa from its attachment to the posterior nasal spine till pterygopalatine fossa, whereas the second group underwent conventional nasal mucosa release.

Results

The postoperative length was significantly higher among patients managed with the radical release technique of 24.4 ± 3.5 mm compared to 22.6 ± 2.5 mm in the traditional release technique. The velopharyngeal port size significantly decreased in the radical release group from 15.0 ± 2.4 mm to 10.7 ± 2.4 mm, compared to the traditional group from 15.0 ± 2.7 mm to 12.5 ± 3.2 mm (P-value < 0.001).

Conclusions

Radical release of the nasal mucosa from the posterior nasal spine to the pterygopalatine fossa enhances the palatal lengthening compared to the traditional release of the nasal mucosa, allowing tension-free closure of the cleft palate, and decreases the incidence of palatal fistula. Level I, therapeutic study.
