Perichondritis is an infection or inflammation involving the perichondrium of the external ear. It occurs usually secondary to trauma and is mostly caused by P. aeruginosa but can be polymicrobial. It should be differentiated from cellulitis of the ear, classically by being lobule sparing.

The most common indication for this is residual or recurrent tumor. This may be clinically obvious, be suggested by serial CT scanning, or present as intractable “perichondritis.” Diagnosis of tumor in relation to the latter may only be possible by careful examination of the laryngectomy specimen. Chronic pain, dysphonic voice, and airway compromise (which in itself sometimes necessitates a tracheostomy) will often lead the patient to request surgery even in the absence of overt tumor recurrence. Another indication is a larynx that is scarred and incompetent, usually several years post-RT. The symptoms usually precipitating the decision to proceed with surgery are chronic stridor, pain, and/or intractable aspiration.
Ear

While perichondritis indicates infection of the surrounding tissue of the auricular cartilage (the outer third of the ear canal), chondritis indicates infection of the cartilage itself. This is usually caused by trauma, such as ear piercing.

Our technique can effectively enlarge the meatal cross-sectional S. The postoperative V/S is closer to the normal ears than that without conchoplasty and the greater the difference from the normal V/S, the longer the ear drying time. We have managed to achieve a dry, auto-cleaning ear with very good cosmetic results in all cases. We have not had any cases of stenosis or troublesome granulation, cholesteatoma recurrence, perichondritis, auricular deformity and other complications. Epithelialization of the cavity and cosmetically successful outcomes were achieved in all cases. Perichondritis secondary to cartilage excision, although theoretically possible, has not been observed in our cases. This is consistent with many authors’ reports [5 and 6,15–17]. We believe that strict aseptic operation, careful dressing changes and rational use of antibiotics can avoid auricular perichonditis as much as possible [18]. In addition, the cartilage removed during we performed C-conchoplasty may be used as a good material for tympanoplasty and mastoid obliteration. The good cosmetic appearance of the concha postoperative is shown in Figures 5 and 6. No patients performed with our technique have complained about poor cosmesis on follow-up. In the end, a large external auditory meatus allows ventilation of the mastoid cavity as well as easy access for examination and debridement of the entire cavity.
The benefits of ultrasonography in diagnosing and assessing auricular chondritis, arthritis, and tenosynovitis in a patient with relapsing polychondritis

In October 2014, biopsy of the right auricle was performed. Histology indicated perichondritis; inflammatory cells, mainly neutrophils, had infiltrated into the cartilage and its surroundings. Around the aggregation of neutrophils, the edge of the cartilage was irregular and eosinophilic changes in the cartilage were noted. Angiogenesis was observed in the subcutaneous tissues in the vicinity of the cartilage, but not in the cartilage itself. Subcutaneous tissue surrounding angiogenesis was edematous (Figure 3(a,b)). These histological findings indicated early stage RP. She was diagnosed with RP according to McAdam’s criteria: fulfilment of bilateral auricular chondritis, non-erosive and non-deforming inflammatory polyarthritis, ocular inflammation, and audiovestibular damage with a histology of auricular chondritis.

Differentials depend on the organ involved in the course of RPC (Table 3). An auricular chondritis with sparing of the lobule is relatively unique to RPC. Infectious perichondritis can look similar except that the lobule is involved as well. The most common pathogen to cause it is due to Pseudomonas aeruginosa or Staphylococcus aureus [4,5]. The auricular deformation can be caused by trauma, leprosy, leishmaniasis, and frostbite[62]. Saddle nose deformity can be caused by trauma, leprosy, congenital syphilis, septal hematoma, perforation induced by cocaine inhalation, sarcoidosis, and granulomatosis with polyangiitis (GPA)[63]. Ocular inflammation can be seen in rheumatoid arthritis, polyarteritis nodosa, sarcoidosis, Behçet’s disease, systemic lupus erythematosus (SLE), seronegative spondyloarthropathies. Symptoms of respiratory tract involvement can be confused with asthma or bronchitis. The stenosis of the airway also occurs in GPA, sarcoidosis, and amyloidosis. Aortic or mitral regurgitation and aortic aneurysms can be present in several vasculitis diseases such as (giant cell arteritis, Takayasu’s disease, or Behçet’s disease), syphilis (syphilitic aortitis), genetic disorders (Marfan’s and Ehlers–Danlos syndrome)[10]. GPA and RPC are two conditions that overlap, and they can mimic the other in terms of clinical presentation (e.g. GPA can cause ocular inflammation, septal perforation, polyarticular arthritis, and hearing loss). Differentiating GPA features include sinusitis, parenchymal lung disease, renal involvement, c-ANCA positive serology, and epithelioid cell granulomas in biopsy [64,65].
