Table I-1Applicability for KQ 1
| Domain | Description of applicability of evidence |
|---|---|
| Population | Studies examining the effectiveness of ankyloglossia treatment had significant differences in population. Specifically, there was age heterogeneity between the 3 good quality trials: ranging from group means of 28d and 33d for patients treated with frenotomy versus sham in one study1, an overall median 6d +/- 6.9 in another 2, and group medians 11d (IQR 8 – 14) and 11d (IQR 8 – 16) in the third.3 Gender distribution was ∼2:1 in 2 trials,1, 2 and not reported in the third. 3 Finally, ankyloglossia severity was only rated in 1 trial, which also excluded the most severe cases (HATLFF > 6), thus potentially biasing its results toward the null hypothesis3. |
| Intervention | All comparative studies assessed the role of surgical intervention. Procedural specifics were consistent across studies although tongue-tie division terminology differed (i.e. frenotomy, frenulotomy). No comparative study considered alternative treatments for ankyloglossia and its effect on breastfeeding. |
| Comparators | Two comparators were used: sham1, 2 and no intervention3. These are synonymous except in relation to blinding of participants since no intervention was performed even in either group. No treatment is a common alternative to frenotomy and therefore its use is broadly applicable to the overall population at risk for ankyloglossia and its sequelae. |
| Outcomes | There was fair homogeneity among outcome measures used in these studies, which consisted of assessment of breastfeeding effectiveness and maternal nipple pain. However, the means of measuring breastfeeding effectiveness differed among studies. In one RCT, effectiveness was assessed both by maternal-report and objective observer immediately after frenotomy or sham.1 A second RCT employed an objective observer to assess breastfeeding effectiveness (IBFAT) compared to sham immediately post-procedure.2 The third RCT had an objective observer score breast latch using the LATCH and IBFAT outcome measures.3 Nipple pain was assessed using either a visual analog scale (VAS) or the Short-form Montreal Pain Questionnaire (SF-MPQ). While VAS-type scales are commonly used for pain, specific levels may not be widely applicable to other populations of women breastfeeding a newborn with ankyloglossia. |
| Setting | The setting was variably reported in these studies. Frenotomy were performed in tertiary care hospitals and clinics and performed by pediatric surgeons, lactation consultants, and otolaryngologists. Two of three RCTs were not explicit whether frenotomy was performed as an inpatient or outpatient. |
Table I-2Applicability for KQ 2a
| Domain | Description of applicability of evidence compared to question |
|---|---|
| Population | Neonates born with congenital ankylglossia between January 2010 and December 2010 |
| Intervention | Frenotomy within first month of life |
| Comparators | Offered but declined frenotomy within first month of life; may or may not have received non-surgical interventions |
| Outcomes | Paternal (typically maternal) report of the 3 year old's difficulty: (1) cleaning teeth with the tongue, (2) licking the outside of the lips, and (3) eating ice cream |
| Timing | Outcomes measured at 3 years of age |
| Setting | Academic medical center hospital in a large, urban area |
Table I-3Applicability for KQ 2b
| Domain | Description of applicability of evidence compared to question |
|---|---|
| Population | The study population primarily consisted of children with tongue-tie and perceived speech impairment, though inclusion criteria were not explicit. There was a small subset of pre-lingual patients who were treated for fear of speech impediment, though no speech concern had been diagnosed at the time of intervention. |
| Intervention | All interventions in this group were surgical. A variety of surgical techniques were utilized, included simple division with scalpel, scissors, and CO2 laser 4, frenulectomy/frenulotomy,5 frenuloplasty,6, 7 and the addition of genioglossus myotomy.8 |
| Comparators | The majority of studies were non-comparative case series. Among the comparative studies, two cohort studies compared children with ankyloglossia after surgical management to those with ankyloglossia without surgical management and non-tongue-tied controls. A single RCT compared 4-flap frenuloplasty to horizontal to vertical frenuloplasty |
| Outcomes | Follow-up intervals ranged from several months to 3 years. Many studies evaluated speech improvement using parental self-report, including one of the cohort studies.9 The second cohort study10 measured articulation, and speech understandability with word, sentence and connected speech, as evaluated by blinded speech pathologists. |
| Setting | The setting was varied and variably reported in these studies. Procedures were performed in nurseries, outpatient clinics and in operating rooms, with no anesthetic, local and general anesthetic all being used. Pediatric surgeons, plastic surgeons and otolaryngologists performed the surgeries. Most studies were based in the United States, with a single study from each India, Korea, China and the United Kingdom. |
Table I-4Applicability for KQ 3
| Domain | Description of applicability of evidence for a key question |
|---|---|
| Population | The population studied in the question of benefit of ankyloglossia repair for social concerns included children and adults with wide variation in ages. The patients were selected either by retrospective chart review or as they presented to otolaryngology clinics. |
| Intervention | Surgical repair only |
| Comparators | None |
| Outcomes | Outcomes measured were not consistent between studies with social concerns measured as a secondary outcome and the types of social outcomes considered were not consistent |
| Setting | Setting was inconsistently reported but most often surgeries occurred in outpatient settings. |
