Anterior cervico-thoracic osteophytes: an unusual cause of dysphagia

Anterior cervical osteophytes causing dysphagia: Choice of the approach and surgical problems

Background

Anterior cervical osteophytes (ACOs) may rarely cause dysphagia, dysphonia, and dyspnea. Symptomatic ACOs are most commonly located between C3 and C7, whereas those at higher cervical (C1-C2) levels are rarer. We report a case series of 4 patients and discuss the best surgical approach according to the ostheophyte location and size, mainly for those located at C1-C2, and the related surgical problems.

Materials and Methods

Four patients (two males and two females) aged from 57 to 72 years were operated on for ACOs, causing variable dysphagia (and dyspnea with respiratory arrest in one). Three patients with osteophytes between C3 and C5 were approached through antero-lateral cervical approach, and one with a large osteophyte between C1 and C3-C4 level underwent a two-stage transcervical and transoral approach. All had significant postoperative improvement of dysphagia.

Results

The patient operated on though the transoral approach experienced postoperative flogosis of the prevertebral tissues and occipital muscles and thrombosis of the right jugular vein and transverse-sigmoid sinuses (Lemierre syndrome).

Conclusion

The transoral approach is the best surgical route to resect C1 and C2 ACOs, whereas the endoscopic endonasal approach is not indicated. The anterior transcervical approach is easier to resect osteophytes at C3, as well as those located below C3. A combined transoral and anterior cervical approach may be necessary for multilevel osteophytes.

Diffuse idiopathic skeletal hyperostosis of the cervical spine: an underestimated cause of dysphagia and airway obstruction

BACKGROUND CONTEXT

Diffuse idiopathic skeletal hyperostosis (DISH) is a common but underdiagnosed condition relating to ossification of spinal ligaments that can cause compression of the esophagus and trachea. According to case reports, dysphagia or airway obstruction resulting from DISH is a rare occurrence.

PURPOSE

This study was intended to identify all published cases of dysphagia and/or airway obstruction resulting from DISH to increase the epidemiologic/clinical knowledge of these related conditions.

STUDY DESIGN

A systematic review of the literature was performed.

METHODS

The articles resulting from the systematic PubMed/EMBASE search of the literature were closely read, and predefined parameters were scored.

RESULTS

The search yielded a total of 118 articles (95 case reports and 23 case series) describing 204 patients with dysphagia and/or airway obstruction resulting from DISH. The number of cases demonstrated a steady increase from 1980 to 2009. This might be a real effect not ascribable to publication bias or expansion of the medical literature alone.

CONCLUSIONS

Diffuse idiopathic skeletal hyperostosis as a cause of dysphagia and/or airway obstruction may be an increasing and underappreciated phenomenon. Diffuse idiopathic skeletal hyperostosis should be included in the differential diagnosis of dysphagia and airway obstruction.
