Effects of lip revision surgery on long-term orosensory function in patients with cleft lip/palate.

Abstract

OBJECTIVE:

To determine whether secondary lip revision surgery impacts sensitivity of the upper lip.

DESIGN:

A three-group, parallel, prospective, nonrandomized clinical trial.

SETTING:

University of North Carolina School of Dentistry.

PATIENTS, PARTICIPANTS:

Three groups: (1) patients with repaired cleft lip/palate who were scheduled for lip revision (revision; N = 20); (2) patients with repaired cleft lip/palate who did not receive a lip revision (non-revision; N = 13); and (3) non-cleft control subjects (non-cleft; N = 22).

INTERVENTIONS:

Lip revision surgery.

MAIN OUTCOME MEASURES:

Measures of (1) two-point perception threshold (two-point), (2) warmth detection threshold (warm), and (3) cool detection threshold (cool) were obtained from two sites on the upper lip vermilion. The revision participants were tested approximately 1 week before surgery and then approximately 3 and 12 months after surgery. The non-revision and non-cleft participants were tested at similar times.

RESULTS:

There were no significant differences among the three groups at baseline for two-point, warm, or cool. The main effects of group, age, sex, and time were not statistically significant for the two-point or warm (p > .05). The mean differences between the 3- and 12-month follow-up visits and baseline for two-point and warm were small for all three groups. For cool, group was statistically significant (p = .04), the difference in the non-revision group between follow-up and baseline was 31% to 34% higher than in the non-cleft group (p = .01).

CONCLUSIONS:

Although at postsurgery revision participants exhibited threshold values comparable to presurgical values, the sensory differences observed among subgroups of participants with cleft lip are complex.
