Endoscopic sinus surgery and postoperative intravenous aminoglycosides in the treatment of atrophic rhinitis

Chronic rhinosinusitis in ex-lepromatous leprosy patients with atrophic rhinitis

AIM

Rhino-sinus mucosal involvement is well documented in untreated lepromatous leprosy, but less understood in ex-leprosy patients (i.e. leprosy patients who have been treated and cured) with atrophic rhinitis.

MATERIALS AND METHODS

Rhino-sinus abnormalities were investigated in 13 ex-lepromatous leprosy patients with atrophic rhinitis, using interviews enquiring about sinonasal symptoms, nasal endoscopy, nasal swab culture and computed tomography. Endoscopic sinus surgery had been performed in three patients. The clinical course, computed tomography findings and nasal biopsy results of these three patients were evaluated.

RESULTS

All patients had turbinate atrophy and 6 of the 13 (46.2 per cent) had septal perforation. Paranasal sinus involvement was noted in 9 of 12 examined patients (75 per cent). The most commonly affected sinus was the maxillary sinus (in 8 of 12; 66.7 per cent). All three patients treated by endoscopic sinus surgery experienced relapse and required further surgery. Maxillary sinus irrigation was effective for reduction of persistent symptoms such as postnasal discharge and crusts.

CONCLUSION

Ex-lepromatous leprosy patients with atrophic rhinitis had various rhino-sinus abnormalities and persistent symptoms. These patients had chronic rhinosinusitis because of underlying atrophic rhinitis. These patients required repeated otolaryngological observations together with combined surgery and conservative treatment.

Physiology and pathophysiology of respiratory mucosa of the nose and the paranasal sinuses

In this review, anatomy and physiology of the respiratory mucosa of nose and paranasal sinuses are summarized under the aspect of its clinical significance. Basics of endonasal cleaning including mucociliary clearance and nasal reflexes, as well as defence mechanisms are explained. Physiological wound healing, aspects of endonasal topical medical therapy and typical diagnostic procedures to evaluate the respiratory functions are presented. Finally, the pathophysiologies of different subtypes of non-allergic rhinitis are outlined together with treatment recommendations.

Medical management in functional endoscopic sinus surgery failures

Functional endoscopic sinus surgery has a high rate of success, ranging from 75 to 95% improvement in symptoms for patients who have medically refractory chronic rhinosinusitis. However, symptom improvement does not necessarily correlate with disease resolution, and even asymptomatic patients may require long-term medical management and endoscopic surveillance if late recurrence is to be avoided. The 5 to 25% percent of patients who continue to have symptoms create a challenge for the rhinologist. Correct diagnosis is the hallmark of successful treatment of this recidivistic population, carried out through history, nasal endoscopy, and radiologic (computed tomography) studies. Particularly in patients with a primary complaint of headache or facial pain, the initial preoperative diagnosis should also be revisited, particularly before further surgical intervention is considered. Once a proper diagnosis is made, management is multifaceted, including topical and systemic medications, and mechanical improvements in the sinus drainage pathways, either through treatments in the office or revision surgery. Therefore, we strongly recommend that chronic rhinosinusitis be viewed as a medical disease in which surgery plays a therapeutic role. Frequently, persistent inflammation slowly settles down over time with appropriate medical management.
