Hearing sensitivity in adults with a unilateral cleft lip and palate after two-stage palatoplasty.

OBJECTIVE: To evaluate long-term hearing and middle ear status in patients treated for a unilateral complete cleft lip and palate (UCLP) by two-stage palatoplasty. METHODS: Forty-nine UCLP patients aged 17 years and older were included in this retrospective study. Patients were invited for a multidisciplinary long-term follow-up of their treatment at a tertiary center for craniofacial surgery in the Netherlands. ENT assessment included tympanometry and pure-tone audiometry. Medical files were searched for medical and surgical history. RESULTS: In total, 19.4% of the patients had significant long-term hearing loss (PTA > 20 dB), comprising conductive hearing loss in 21.5% of the patients. In the majority (70%), this hearing loss was more pronounced at higher frequencies. In 25% the high fletcher index showed hearing thresholds above 20 dB. Ventilation tubes were placed at least once in 78.7% of the patients. The frequency of tube insertion was positively correlated with the incidence of reduced tympanic compliance (tympanogram type B) and the need for a pharyngoplasty. CONCLUSION: The present study reports long-term hearing outcomes in UCLP patients with hard palate closure at 3 years of age. Persistent hearing loss was observed in 19.4% of our patients (PTA > 20 dB), mainly at the higher frequencies. Ventilation tube placement was associated with reduced tympanic compliance and higher risk on hearing loss (PTA air conduction). Our high incidence of velopharyngeal incompetence during early childhood, which is likely associated with Eustachian tube dysfunction, might have contributed to these results.

Long-term mid-facial growth of patients with a unilateral complete cleft of lip, alveolus and palate treated by two-stage palatoplasty: cephalometric analysis.

OBJECTIVES: The aim of this study is to evaluate long-term facial growth in adults previously treated for an isolated unilateral complete cleft lip, alveolus and palate by two-stage palatoplasty. MATERIALS AND METHODS: Unilateral cleft lip and palate (UCLP) patients of 17 years and older treated by two-stage palatoplasty were invited for long-term follow-up. During follow-up, lateral cephalograms were obtained (n = 52). Medical history was acquired from their medical files. Outcome was compared to previously published normal values and the Eurocleft study. RESULTS: Soft and hard palate closure were performed at the age of 8 (SD 5.9) months and 3 (SD 2.2) years, respectively. The mean maxillary and mandibular angle (SNA, SNB) were 74.9° (SD 4.2) and 75.8° (SD 3.8). Maxillary and maxillomandibular relationships (SNA, ANB) were comparable to all Eurocleft Centres, except for Centre D. We observed a significantly steeper upper interincisor angle compared to the Eurocleft Centres. CONCLUSIONS: This study describes the long-term craniofacial morphology in adults treated for a UCLP with hard palate closure at a mean age of 3 years. The mean maxillary angle SNA and mandibular angle SNPg were comparable to previous studies both applying early and delayed hard palate closure. The observed upper incisor proclination is likely caused by orthodontic overcorrection in response to the unfavourable jaw relationships. No clear growth benefit of this protocol could be demonstrated. CLINICAL RELEVANCE: The present study shows the long-term craniofacial morphology of UCLP adults after the Utrecht treatment protocol which includes two-stage palate closure.
