The aim of the study is to give an idea about true incidence and most common location of fallopian canal dehiscence and to identify predictive factors associated with fallopian canal dehiscence based on preoperative and peroperative clinical correlates so as to facilitate preemptive prediction of the condition. The study design pertains to a prospective study. The setting of the study was tertiary referral hospital and a total of 146 patients underwent radical and modifi ed radical mastoidectomy as primary procedure between Jan. 2003 to Dec. 2004. The site of dehiscence and associated pre-operative and per-operative fi ndings were noted. Our results showed the incidence of fallopian canal dehiscence among cases undergoing radical and modifi ed radical mastoidectomy was 82/1000 per year. Around 66.6% dehiscence was located in tympanic segment. The preoperative factors signifi cantly associated with the fallopian canal dehiscence (p< 0.05) were Aural polyp, Extra-cranial complications, Cholesteatoma and Facial palsy. Per-operative fi ndings were Cholesteatoma, All ossicles necrosed except stapes footplate and Lateral semicircular canal fi stula.

The aim of this randomized control trial, performed at a tertiary referral hospital, was to compare the therapeutic effectiveness of two novel treatment modalities, oral rifampicin and submucosal placentrex injection, in randomly selected patients of primary atrophic rhinitis regarding objective, subjective and histopathological improvement. Patients treated with oral rifampicin showed most promising results regarding objective, subjective and histopathological improvement with maximum disease-free interval on regular follow-up as compared to submucosal placentrex injections.

Odontogenic myxoma of maxilla is a very rare occurrence. It is a slow growing benign, locally malignant tumor notorious for recurrence. Hereby we present a case of recurrent odontogenic myxoma of the maxilla in a 32-year-old male managed surgically by partial maxillectomy. The diagnostic and operative dilemmas encountered while managing the case are discussed in detail.

Chondrosarcoma, the most malignant cartilageneous tumor, constitute only 4% of non-epithelial tumours of the nasal cavity, paranasal sinuses and nasopharynx, making it one of the rarest malignancies. 1,3 Here we present a case of Grade 1 chondrosarcoma involving nose, maxillary sinus, ethmoids and sphenoid sinus managed surgically by wide excision. 12 months follow-up reveled no recurrence or complication.
