Bilateral conductive deafness related to erosive lichen planus

Vulvar-vaginal-gingival-otic syndrome

In order to retrospectively analyse the multi-site involvement pattern of erosive lichen planus patients, we retrospectively reported the clinical and medical data of three patients with erosive lichen planus which involving their vulva, vagina, gingiva, and ear canal. We confirmed the existence of otic lichen planus, and found that it is more common in patients with vulvovaginal-gingival syndrome of erosive lichen planus. Therefore, we propose 'vulvovaginal-gingival-otic syndrome' to further describe this rare compound pattern of lichen planus.

A Rare Case of Post Inflammatory Lateral Stenosis of External Auditory Canal and It's Management with Review of Literature

Acquired external auditory canal stenosis is a challenging condition to treat and can affect any age group. Post inflammatory lateral canal atresia is uncommon. This article focuses on a 2 year old child who presented with hearing loss with history of otitis externa. The lateral part of Auditory Canal was completely stenosed. He underwent debrider assisted endoscopic ear surgery and stenting, and a patent External Auditory Canal with normal hearing was achieved.

Postinflammatory Medial Meatal Fibrosis: Histopathologic Features and Outcomes of Surgical Management

OBJECTIVES

The aims of our study were to investigate the clinical and audiometric outcome of the surgical treatment of postinflammatory medial meatal fibrosis (PIMMF) and to review the histopathologic changes in the specimens of the fibrotic plug, in order to try to shed light on the pathogenesis of the disease.

MATERIALS AND METHODS

The clinical records and the histopathologic specimens of all patients who underwent tympanomeatoplasty for PIMMF at the ENT Clinic of the University of Erlangen between 2006 and 2020 were evaluated retrospectively.

RESULTS

Thirty-four patients (41 primary surgical procedures) made up our study cohort. Of this, 28 cases were managed by means of meatoplasty and 13 cases with tympanomeatoplasty. The mean preoperative air-bone gap (ABG) was 27.8 dB (10-44 dB). Postoperative ABG was significantly improved compared to preoperative values at both short- and long-term follow-ups (P < .001 for both). No significant difference was noted between short-term and long-term ABG (P = .240). An ABG ≤20 dB was achieved in 65.8% of patients (short term) and 50% (long term). The overall rate of revision surgery for restenosis was 29.3% (12/41). Histopathologic reevaluation of the fibrotic plugs revealed a mosaic of patterns with frequent occurrence of secondary cholesteatoma-like lesions and keloid-like tissue changes. Lichenoid submucosal inflammation and increased ectopic ceruminous gland lobules were seen less frequently.

DISCUSSION

The moderate long-term outcome of surgical management and the identification of histologic changes with therapeutic implications might pave the way for alternative nonsurgical treatment options.

Lichen planus of the external auditory canal: Treatment options and review of literature

Medical topic therapies can relieve symptoms associated with lichen planus of external auditory canal. Further, bone‐anchored hearing devices represent an optimal solution for hearing restoration in otic lichen planus.

Post-inflammatory acquired atresia of the external auditory canal

Acquired atresia of the external auditory canal (EAC) is a rare cause of conductive hearing loss. It has been traditionally classified into 4 categories: traumatic, post-operative, neoplastic and inflammatory. Post-inflammatory acquired auditory canal atresia is thought to be the result of chronic and repetitive infectious bouts affecting the auditory canal. Nevertheless, the underlying pathophysiology of this disorder is yet to be fully elucidated. Current data fail to clearly state the impact that certain underlying systemic disorders may have on the EAC. The possible association to metabolic disturbances such as iron deficiency is also emphasized. In the light of these findings, this analysis can be used to improve the classification of this entity thereby standardizing the assessment of therapeutic approaches.

Hypertrophic recurring lichen planus of the external auditory canal

INTRODUCTION

We report a case of unilateral progressive primary hypertrophic lichen planus of the external auditory canal requiring several surgical interventions to deal with constant pruritus, otorrhoea, stenosis and conductive hearing loss.

CASE SUMMARY

A 58-year-old woman was initially treated with meatoplasty for suspected chronic obliterating otitis externa. She remained symptom-free for 5 years, before the disease recurred, affecting other body surfaces as well. Otorrhoea, conductive hearing loss and pruritus worsened, and a canal wall down tympanomastoidectomy was performed, removing the skin of the external auditory canal and the tympanic membrane completely. Lichen planus was confirmed histopathologically.

DISCUSSION

Very few surgical results have been published on stenosis of the external auditory canal caused by lichen planus. Complete medial external auditory canal skin elevation and removal with postoperative split-skin grafting is advised for initial treatment. We discuss treatment options and surgical outcome after initial surgical failure.

'Nasal flossing': A case report of nasopharyngeal stenosis due to severe erosive lichen planus and a novel therapeutic intervention

INTRODUCTION

We describe a case of severe erosive oral lichen planus that led to nasopharyngeal stenosis. This is a rare clinical presentation that was ultimately, successfully treated by surgery combined with post-operative 'nasal flossing': a novel therapeutic intervention.

PRESENTATION OF CASE

A 76-year-old male suffering from a rare case of severe oral lichen planus that was resistant to conservative measures is described. Initial surgery was complicated by recurrence of nasopharyngeal stenosis. Definitive surgery required revision of nasopharyngeal stenosis release combined with a course of post- operative 'nasal flossing'. The technique for 'nasal flossing' is described and demonstrated in photographs. The patient remained asymptomatic at 3 years using this combined approach, with restoration of olfaction, taste perception and voice quality, significantly enhancing quality of life.

DISCUSSION

Erosive oral lichen planus is a rare but important presentation in oral medicine. We found 'nasal flossing' to be a successful treatment to maintain nasopharyngeal patency following surgical repair of this uncommon condition. We are not aware that this combined approach has previously been described in the published literature.

CONCLUSIONS

Severe erosive oral lichen planus can lead to nasopharyngeal stenosis. Nasopharyngeal stenosis in these patients may be refractive to conventional surgical approaches. 'Nasal flossing' is demonstrated to be both practical and acceptable as a surgical adjunct in these difficult to treat cases of recurrent nasopharyngeal stenosis. This report has relevance for all those practicing oral and maxillofacial surgery, ear nose and throat surgery and oral medicine.

Koebner phenomenon of the ear canal skin

The Koebner phenomenon originally described the appearance of psoriatic lesions in the uninvolved skin of patients with psoriasis as a consequence of trauma. We describe a case of concurrent lichen planus and sarcoidosis in the auditory canal, which represents an unusual manifestation of the Koebner phenomenon. This is the first case of concurrent lichen planus and sarcoidosis in the head and neck region and highlights the need for biopsy to allow accurate histopathological diagnosis and treatment.

Idiopathic, inflammatory, medial meatal, fibrotising otitis presenting with lichen planus

Background:

Background: Of the acquired ear canal atresias, idiopathic, inflammatory, medial meatal, fibrotising otitis has been suggested as a distinct disease entity, for reasons of aetiology.

Objective:

To report three more cases of idiopathic, inflammatory, medial meatal, fibrotising otitis and to further consider the possible relationship between this condition and lichen planus.

Patients:

Three adult patients with idiopathic, inflammatory, medial meatal, fibrotising otitis, two with bilateral aural symptoms, treated and followed up at the department of otorhinolaryngology of Helsinki University Hospital.

Results:

We found idiopathic, inflammatory, medial meatal, fibrotising otitis, affecting solely the glabrous skin of the osseous part of the external ear canals, in three patients who also suffered from severe oral lichen planus.

Conclusions:

The aetiopathology or pathophysiology of idiopathic, inflammatory, medial meatal, fibrotising otitis may be linked with lichen planus. Early, active treatment of idiopathic, inflammatory, medial meatal, fibrotising otitis with local corticosteroids may prevent total medial meatal atresia.

The vulvovaginal gingival syndrome: A severe subgroup of lichen planus with characteristic clinical features and a novel association with the class II HLA DQB1∗0201 allele

BACKGROUND

The vulvovaginal gingival syndrome is an uncommon and severe variant of lichen planus characterized by erosions or desquamation of vulval, vaginal, and gingival mucosae with a predilection for scarring and stricture formation.

OBJECTIVE

We sought to define the clinical, immunopathologic, and human leukocyte antigen findings in a large cohort of patients.

METHODS

The clinical presentation and outcome during long-term follow-up were documented in 40 patients. In addition, human leukocyte antigen typing for class II by polymerase chain reaction and sequence-specific primers was performed.

RESULTS

During a mean follow-up period of 8.7 (SD +/- 6.8) years, long-term sequelae included strictures of the esophagus, lachrymal ducts, and external auditory canal; loss of vulval architecture; vaginal stenosis; and buccal mucosal fibrosis. The DQB1( *)0201 allele was present in 80% of patients versus 41.8% of control subjects (P <or= .0042; relative risk 3.71).

CONCLUSION

Early diagnosis of this distinct subgroup of lichen planus, combined with appropriate therapeutic measures, may help to minimize the significant physical and psychologic morbidity associated with this scarring disorder.
