Summary
Orthognathic surgery, specifically Le Fort I maxillary osteotomies, can lead to ear pain (otalgia) and middle ear changes. Tympanometry reveals these postoperative alterations, offering insights into otalgia causes.
Area of Science:
- Oral and Maxillofacial Surgery
- Otolaryngology
- Audiology
Background:
- Orthognathic surgery, including Le Fort I maxillary osteotomy, is increasingly common.
- Post-surgical complications, such as otalgia, are frequently reported, affecting 25-30% of patients.
- Acute otitis media requiring myringotomy has been observed post-maxillary osteotomy.
Purpose of the Study:
- To investigate changes in tympanometry following total maxillary osteotomy.
- To explore a potential explanation for middle ear changes and associated otalgia.
Main Methods:
- Preoperative and postoperative tympanometric assessments were conducted on patients undergoing total maxillary osteotomy.
- Clinical observations of middle ear changes and patient-reported otalgia were recorded.
Main Results:
- Significant changes in tympanograms were observed after total maxillary osteotomy.
- These tympanometric alterations correlate with the occurrence of otalgia.
Conclusions:
- Total maxillary osteotomy can induce measurable changes in middle ear function.
- These tympanometric findings may explain the incidence of postoperative otalgia.
- Further research is warranted to fully understand the pathophysiology of these ear complications.
