Abstract Objective: To test the null hypothesis that rapid maxillary expansion (RME) with a rigid bonded appliance has no effect on conductive hearing loss (CHL) in growing children. Materials and Methods: Fifteen growing subjects (mean age 13.43 ± 0.86 years) who had narrow maxillary arches and CHL participated in this study. Three pure-tone audiometric and tympanometric records were taken from each subject. The first records were taken before RME (T1), the second after maxillary expansion (T2) (mean = 0.83 months), and the third after retention (mean = 6 months) and fixed appliance treatment (approximately 2 years) periods (T3). The data were analyzed by means of analysis of variance (ANOVA) and least significant difference (LSD) tests. Results: Hearing levels of the patients were improved and air-bone gaps decreased at a statistically significant level (P < .001) during active expansion (T2–T1) and the retention and fixed appliance treatment (T2–T3) periods. Middle ear volume increased in all observation periods. However, a statistically significant increase was observed only in the T2–T3 period. No significant change was observed in the static compliance value. Conclusions: The hypothesis is rejected. RME treatment has a positive and statistically significant effect on both improvements in hearing and normal function of the eustachian tube in patients having transverse maxillary deficiency and CHL.

Subjective Outcomes

The Bonebridge and Vibrant Soundbridge systems are semi-implanted hearing devices, which have been widely applied in patients with congenital conductive hearing loss. However, comparison between these two hearing devices is rare, especially in the same patient. We report a 23-year-old man who underwent successive implantation of Vibrant Soundbridge and Bonebridge devices in the same ear because of dysfunction of the Vibrant Soundbridge. We provide insight on the patient’s experience and compare the audiological and subjective outcomes of satisfaction.

Proteus syndrome (PS) is a rare hamartomatous disorder characterized by mosaic overgrowth of multiple tissues that manifests early in life and is progressive. The presence of unilateral external auditory canal exostoses in a patient who is not a swimmer or surfer is suggestive of PS. However, hearing loss is not a typical feature. Here, we describe exostoses and ossicular discontinuity with conductive hearing loss in a patient with PS. The treatment consisted of canalplasty and ossicular chain reconstruction. A postoperative reduction was demonstrated in the patient's air-bone gap, from 21 dB to 13 dB for the pure tone average (four frequencies) and from 41 dB to 15 dB in the high-frequency range (6,000 to 8,000 Hz). Causes of ossicular discontinuity are discussed. Routine annual audiometric and otolaryngological evaluation should be considered in all patients with temporal bone inyolvement of PS.
