Bottom Line: In addition, postoperative dimensions of the velopharynx were measured by a single-blind examiner using a computed tomography scan.Our comparative study found statistically significant differences between the 2 groups in favor of the unilateral uvuloplasty group.We observed that the use of unilateral uvuloplasty for uvular reconstruction reduces the velopharyngeal space and the frequency of hypernasality in patients with bilateral cleft palate.

ABSTRACT

Background: The conventional method for uvular repair suturing the 2 hemi-uvulas of the palatal cleft together in the midline does not allow us to obtain a proper anatomical repair. In our hands, the midline straight closure frequently causes retraction of the uvular tissues with the consequent abnormal appearance of the uvula. We described before a method for uvular repair in patients with cleft palate. The technique consists in preserving one of the hemi-uvulas, which is moved to the midline to form the definitive uvula. The purpose of this study was to evaluate the functional effects of the unilateral uvuloplasty for uvular repair in a group of patients with bilateral cleft palate.

Methods: This is a retrospective, single-blinded cohort study between 2 groups of 90 patients with bilateral cleft palate who were operated on using the conventional and unilateral uvuloplasty methods of uvular repair from 2000 to 2009. Data collection was accomplished by physical examination to evaluate the presence of postoperative fistulas and hypernasal speech determined at 6 months to 5 years after surgery. In addition, postoperative dimensions of the velopharynx were measured by a single-blind examiner using a computed tomography scan.

Results: Our comparative study found statistically significant differences between the 2 groups in favor of the unilateral uvuloplasty group.

Conclusions: We observed that the use of unilateral uvuloplasty for uvular reconstruction reduces the velopharyngeal space and the frequency of hypernasality in patients with bilateral cleft palate.

Mentions: Morphological evaluation of the velopharyngeal space was performed at rest using a computed tomography scan in a randomized sample of 40 patients from each group at 5 years of age. Using the syngo fastView software (Siemens AG Medical Solutions, Erlangen, Germany), velar length, pharyngeal depth, and velopharyngeal distance were measured by one person to eliminate interoperator errors (Fig. 10). Velar length was estimated from the tip of the posterior nasal spine to the tip of the uvula. Pharyngeal depth was estimated from the margin of the posterior pharyngeal wall at the junction of the palatal plane to the tip of the posterior nasal spine. Velopharyngeal distance was estimated from the margin of the posterior pharyngeal wall at the junction of the palatal plane to the top of the nasal surface of the soft palate. Outcome assessment for each patient was performed by a blind evaluator.
