“…Furthermore, maxillary repositioning can change the hearing capacity through generating tension and edema in the masticatory muscle and, consequently, excess pressure on the adjacent structures [8,9]. The impact of some general factors such as edema in the areas surrounding the hearing tube, which are of osteotomy surgery side effects or some procedures such as nasal intubations, on the function of the Eustachian tube is confirmed [10]. Some of the anesthetic agents in prolonged surgeries can cause the dysfunction of the Eustachian tube cilia and resultant hearing dysfuction [12].…”

“…A surgical procedure such as improper osteotomies of the pterygoid area, which is near the attachment of the hearing tube and operative muscle of the Eustachian tube can also interfere with normal auditory function. Factors such as trauma and the scar of the muscles around the hearing tube can reduce the hearing capacity [10]. Mandibular movements may probably affect the hearing capacity because of the proximity of the condyle and TMJ to the ear structures and common neurovascular systems of these areas [3,11].…”

“…Most of these studies considered the maxillary osteotomy more critical than the mandible. Changes in the anatomy of the soft palate and nasopharynx muscles as well as a change in direction and tension of para-tubular muscles, especially in advancement movements, are more emphasized when exploring maxillary surgeries [ 10 ]. A surgical procedure such as improper osteotomies of the pterygoid area, which is near the attachment of the hearing tube and operative muscle of the Eustachian tube can also interfere with normal auditory function.…”

Background Orthognathic surgery is widely used in treating functional and skeletal problems. Any surgical procedure could cause side effects. Objectives This study aimed to evaluate the potential changes in orthognathic surgery on the hearing function of patients. Materials and methods Thirty-one orthognathic surgery candidates were recruited in this study. Patients underwent either single or double jaw surgery. Pure tone audiometry (PTA), tympanometry, and Eustachian Tube Dysfunction Test (ETFT) were performed postoperatively at 24 h, 6 weeks, and 6 months after surgery. Patients were tabulated based on the type of maxilla and mandibular surgical movements (vertical and horizontal). Results PTA evaluation, based on horizontal or vertical movements, did not show significant differences, although vertical movements resulted in less change in hearing threshold. In other words, no significant changes occurred in patients’ hearing threshold after surgery. No significant difference was also observed between horizontal and vertical movements in the results of tympanometry. Negative changes were found in the results of ETFT in vertical movements, which returned to pre-surgery values in the final test. Conclusions The risk of minor changes in hearing function is probable during the first week after orthognathic surgery, but these negative changes will either totally fade or remain negligible. Patients gave informed consent preoperatively, and reassurance postoperatively is prudent.

Requirement for Jagged1-Notch2 signaling in patterning the bones of the mouse and human middle ear

Whereas Jagged1-Notch2 signaling is known to pattern the sensorineural components of the inner ear, its role in middle ear development has been less clear. We previously reported a role for Jagged-Notch signaling in shaping skeletal elements derived from the first two pharyngeal arches of zebrafish. Here we show a conserved requirement for Jagged1-Notch2 signaling in patterning the stapes and incus middle ear bones derived from the equivalent pharyngeal arches of mammals. Mice lacking Jagged1 or Notch2 in neural crest-derived cells (NCCs) of the pharyngeal arches display a malformed stapes. Heterozygous Jagged1 knockout mice, a model for Alagille Syndrome (AGS), also display stapes and incus defects. We find that Jagged1-Notch2 signaling functions early to pattern the stapes cartilage template, with stapes malformations correlating with hearing loss across all frequencies. We observe similar stapes defects and hearing loss in one patient with heterozygous JAGGED1 loss, and a diversity of conductive and sensorineural hearing loss in nearly half of AGS patients, many of which carry JAGGED1 mutations. Our findings reveal deep conservation of Jagged1-Notch2 signaling in patterning the pharyngeal arches from fish to mouse to man, despite the very different functions of their skeletal derivatives in jaw support and sound transduction.
