Theaetiology of these palsies falls into two broad groups: 50per cent are idiopathic (Bell's palsy), while in theremainder, a large group of underlying pathologies canbe demonstrated after appropriate investigation (May,1987). Amongst this latter group, three to four per cent ofcases are associated with infection in the tympanomastoidregion (Takahashi et al., 1985; May, 1987). In children,acute suppurative otitis media is the most commoninfective cause (May, 1987), though rarely serous otitismedia is responsible (Premachandra and Radcliffe, 1989).In contrast, in adults, chronic suppurative otitis media(CSOM) is the more common infective cause. In this adultgroup, cholesteatoma is usually present, with exposure ofthe facial nerve within its tympanic portion (Takahashi etal.. 1985: Savic and Djeric, 1989). Less commonly, specificchronic infections are responsible, such as tuberculosis orsyphilis (De Paep et al, 1989; Linstrom et al, 1993). Thereremains, however, a small group of patients with CSOM inwhich cholesteatoma and specific infection are both absent.We present such a case occurring in an immunocompro-mised patient, in whom aggressive mucosal disease led to acomplete facial palsy.Case historyA 47-year-old man was referred to the ENT Depart-ment at Manchester Royal Infirmary shortly after receivinga cadaveric renal transplant for chronic renal failuresecondary to hypercalcaemia of unknown origin. Aparathyroidectomy was undertaken in the year precedingthe renal transplant. Four months prior to ENT referral, hedeveloped intermittent right-sided otorrhoea, accompa-nied by a decrease in hearing on that side. There were noother symptoms referable to the right ear and no priorotological history of note, other than a longstanding mixedhearing loss of unknown origin in the contralateral ear.Otoscopy of the left ear was normal, while on the rightside, a polyp could be seen obstructing the external canal.Culture of the mucopurulent discharge grew gentamicin-sensitive Pseudomonas aeruginosa while histology of theFIG. 1Pre-operative appearance of right facial palsy (HouseGrade VI).From the University Department of Otolaryngology, Manchester Royal Infirmary, Manchester, UK.Accepted for publication: 14 April 1995.755756 C.

Following aural toilet,audiometry of the right ear was normal.The decision to explore the right ear was made, but thepatient experienced an episode of severe rejection of therenal transplant which required treatment with azathio-prine, prednisolone and cyclosporin. He was subsequentlylost to ENT follow-up.Three months later, he was re-admitted by the renalphysicians with a deterioration in renal function and athree-week history of a complete right lower motorneurone facial palsy (Figure 1). Following stabilization ofhis renal function over the next six weeks, the patientunderwent an exploration of the right mastoid. The polypwas found to be eroding the posterior and inferior wall ofthe deep external meatus. Polypoid tissue filled the middleear and had breached the facial canal, destroying thesection of facial nerve from halfway along the horizontalsegment to a point just distal to the second genu. Theincus, malleus and stapes arch had also been destroyed bythe disease process. A radical mastoid cavity was thereforefashioned. Histology of the polyp and tissue taken from themesotympanum revealed active granulation tissue with noevidence of neoplasia. The cavity continued to dischargepost-operatively and required regular micro-suction andtopical treatment. Five months later, once optimal controlwas achieved, the patient underwent re-exploration of theright ear with repair of the facial nerve using a 15 mmsection of the greater auricular nerve as a cable graft. Thehistological appearance of the proximal facial nerve stumpis shown in Figure 2, demonstrating a surrounding chronicinflammatory cell infiltrate. Subsequent outpatient reviewrevealed initial return of facial function at nine months andwhen last reviewed, some 12 months after the nerve graft.facial nerve function had improved to House Grade IV(Figure 3).DiscussionFacial palsy due to CSOM without cholesteatoma israre. Such palsies are more frequent when cholesteatomais present and unless a congenital dehiscence of thefallopian canal exists, must be preceded by a period ofbone erosion. The pathogenesis of bone resorption incholesteatoma is complex, and may involve more than onemechanism. Pressure from a cholesteatomatous sac mayinduce osteoclastic activity and lead to dehiscence of aportion of bone over the nerve (Chole. 1988). leading to aslowly progressive facial weakness (McGinn et al. f986).However, acquired cholesteatoma is usually associatedwith granulation tissue and infection (Djeric and Savic.1989), with a number of interlinking mechanisms at thecellular and enzymatic level being responsible for boneresorption. Interleukin-I (IL-I) released from tissuemacrophages increases local osteoclast activity and ischemotactic for circulating monocytes and macrophaees(Ahn etal, 1990; Schilling et al. 1992). The rapid growtrTofsquamous epithelium, enhanced by the presence ofinfection (Wells and Michaels. 1991). leads to highnumbers of desquamated cells which may further accel-erate osteoclastic activation by release of IL-I (Schilling etal. 1992). Cells of the macrophage/monocyte series mayalso exhibit osteoclast-like activity, especially if stimulatedby cytokines released from polymorphonuclear leucocytes(Maylot el al. 1991). Interleukin-I is also known toCLINICAL RECORDS 757FIG. 3Post-operative appearance of right facial palsy at 12 months(House Grade IV).stimulate increased production of collagenase and pros-taglandin E2 (PGE2), both of which are produced bybone-resorbing cells (Ahn et al, 1990). Recently, aparathyroid-hormone-like substance has been isolatedfrom cholesteatomata, suggesting a more direct mechan-ism for bone resorption (Cheshire et al, 1991). Osteoclasticbone resorption may lead to dehiscence of the fallopiancanal (Browning, 1987), with subsequent facial paralysis asthe infective process involving the facial nerve trunk(Djeric and Savic, 1990). Granulation tissue in associationwith longstanding infection may lead to polyp formation,impeding drainage via the external auditory meatus andfurther exacerbating the condition.Thomsen and his colleagues in their extensive histolo-gical and histochemical studies on CSOM, noted that boneresorption occurred whether or not cholesteatoma waspresent: however, the magnitude of the resorption wasgreater when cholesteatoma was present (Thomsen et al.1974; 1981). In cases of non-cholesteatomatous CSOM,many of the factors which precipitate bone resorption stillapply. PGE2 has been demonstrated in middle eargranulation tissue to have a similar level of bone resorbingactivity to that in cholesteatoma (Kurihara et al, 1991).Infection will activate cells of the polymorph andmonocyte/macrophage series whether cholesteatoma ispresent or not. However, the desquamating cells incholesteatoma undoubtedly accelerate the immune activa-tion, which may explain the more extensive boneresorption when cholesteatoma is present.In the case we describe, the disease process was soaggressive as to completely destroy a 15 mm section offallopian canal and facial nerve and therefore thepossibilities of malignancy or tuberculous otitis mediawere considered. However, histopathology and microbiol-ogy of tissue obtained at the time of operation werenegative. In view of the onset of facial palsy duringtreatment for acute graft rejection, it is likely that thePseudomonas aeruginosa infection secondary to thepatient's compromised immune status was primarilyresponsible for the extensive nature of the mucosaldisease. This may have led to a necrotizing vasculitis,osteitis and neuritis, much as is seen in malignant otitisexterna. However, the possibility that hyperparathyroid-ism enhanced the osteoclastic activity also has to beconsidered.Despite the creation of an adequately ventilated radicalmastoid cavity, there was persistence of granulation tissueand infection which delayed repair of the facial nerve. Thisgranulation tissue was difficult to eradicate until theimmunosuppressants were returned to maintenancelevels. The treatment of facial palsy secondary to chronicmucosal otitis media, as when cholesteatoma is present, issurgical. The ear must be explored as soon after the onsetof the palsy as possible, with removal of diseased mucosaand creation of adequate drainage and ventilation. Toachieve this, open cavity mastoidectomy is frequentlynecessary (Harker and Pignatari, 1992). With suchtreatment, the majority of patients can expect completerecovery of facial nerve function, though partial recoveryand persistent paralysis have been documented (Savic andDjeric, 1989; Harker and Pignatari. 1992).ConclusionThis report describes a case of non-cholesteatomatousfacial palsy. Unlike previous reports, the palsy wassecondary to complete destruction of a significant segmentof the nerve. The extensive nature of the mucosal disease,coincidence with an episode of severe graft rejectionsuggests that the immunosuppression was significant in thepathogenesis of the facial palsy.ReferencesAhn, J.
