Publication Blood Splashes Risk During Otorhinolaryngology Surgery: A Tertiary Care Hospital Based Study(Kathmandu University, 2018) Shrestha, BL; Dhakal, A; Karmacharya, SABSTRACT Background ENT (Ear, Nose and Throat) surgeons are particularly at high risk of exposure with blood and body fluid related infections both in Outpatient and during surgical procedures. They do take precaution to avoid the needle stick injuries but few pay attention on blood or body fluid splashes into eye. Objective To find out the risk of blood splashes to both surgeon and assistant during otorhinolaryngology surgeries. Method This was an descriptive study and data were collected prospectively in Department of Ear, Nose and Throat-Head and Neck Surgery of Dhulikhel Hospital, Kathmandu University Hospital in 1 year period from 1st January 2017 to 1st January 2018. All the surgical cases were included in the study. The surgeon and assistant wore the glass and mask during the surgery. At the end of the surgery, the glass, mask and gown were inspected for any blood splashes and information was recorded. Result There were total 272 patients with male 119 and female 153. The amount of blood splatter in glass, mask and gown is most common in modified radical mastoidectomy surgery. Likewise, the blood splatter is most common in tonsillectomy in throat surgery and in head and neck surgery, the blood splatter is common in all head and neck surgery. Conclusion The blood splashes is high in various Ear, Nose and Throat surgeries. So it is important to take precaution by surgeon and assistant, like protective mask and glass worn during surgeries to protect from various blood-borne infection transmissions.

Any disease process within this structure mandates thorough anatomical knowledge of the corresponding structure. The High resolution computed tomography (HRCT) temporal bone is the best way to look inside this complex bone. The importance of knowledge about how to read and look inside the CT scan temporal bone lead us develop the Dhulikhel Hospital Check list protocol. This protocol will help aspiring otologist and otolaryngologist to read and know details about the underlying structures. KEY WORDS High resolution computed tomography, Otologist, Temporal bonePublication Endoscopic Transcanal Atticoplasty: How we do it?(Kathmandu University, 2023) Shrestha, BL; KC, AK; Karmacharya, SABSTRACT Endoscopic otological surgery has revolutionized ear surgery. Endoscopes are frequently used in myringoplasty and tympanoplasty, and their use in attic reconstruction (atticoplasty) is gaining popularity. While microscopic surgery for limited attic cholesteatoma and attic retraction (grade III and IV) is difficult especially anterior area, the endoscope has emerged as a new treatment option, offering a 360-degree view of the attic and facilitating the complete removal of diseased tissue.1 We had performed atticoplasty with rigid nasal endoscopes (Karl Storz) of 4 mm diameter and 18-cm length. Our preliminary results showed that transcanal endoscopic atticoplasty is a reliable and safe technique for the surgical management either attic retraction pocket (grade III or IV) or limited attic cholesteatoma.

The cyst is filled with keratin flakes and its wall is composed of keratinized, stratified, squamous epithelium. Epidermoid cysts can occur anywhere on the body, usually along the lines of embryonic fusion and mostly on the face, scalp, neck, chest, and upper back. Around 80% of the epidermoid cysts are seen in ovaries and testicles whereas, in the head and neck, they account for only about 7% and 1.6% of epidermoid cysts are reported in the oral cavity. The condition can be congenital or acquired. Congenital causes are rare and may be caused by the entrapment of ectodermal elements intradermally or subcutaneously during embryogenesis. Acquired causes of an epidermoid cyst may result from traumatic or iatrogenic implantation of epithelial cells into the dermal layer or from obstruction of a pilosebaceous unit in the hair follicle. Surgical excision completes the treatment.

The objective of this report is to present a case of idiopathic bilateral optic neuritis in adult and treatment responses. A nineteen year old female presented with bilateral optic neuritis. It was characterized by decreased visual acuity, painful ocular motility and sluggish pupillary reaction with Relative Afferent Pupillary Defect (RAPD) in left eye, hyperemic and generalized optic disc swelling and central scotoma in Humphrey visual field of both eyes. MRI showed diffuse thickening and irregularly outlined optic nerves of both eyes. Idiopathic bilateral optic neuritis in adults is a rare presentation. Prompt treatment with optic neuritis treatment trial (ONTT) improved the visual outcome. KEY WORDS Bilateral optic neuritis, Optic neuritis treatment trial, Visual fieldPublication Laryngeal Paraganglioma - A Rare Entity(Kathmandu University, 2023) Ghimire, SB; KC, AK; Karmacharya, S; Shrestha, BLABSTRACT Laryngeal paragangliomas are neural crest derived rare neuroendocrine tumors which originates from either superior or inferior laryngeal paraganglia. It arises most commonly in supraglottis with mean age of 44 years and it is three times more common in females. This is a case of 39 years female who underwent endoscopic debulking and excision of tumor for histopathological examination which proved to be poorly differentiated squamous cell carcinoma and received a cycle of chemotherapy that probably resulted in complete resolution of initial mass which was confirmed in subsequent follow up. Futher immunohistochemistry examination diagnosed the case as Laryngeal paraganglioma. With this consideration, how effective is the role of chemotherapy in the management of proven case of Laryngeal paragangliomas? KEY WORDS Chemotherapy, Immunohistochemistry, Laryngeal paragangliomaPublication Mirror Ear: A Rare Case of Polyotia(Kathmandu University, 2024) Amatya, N; Shrestha, BL; Karmacharya, S; Sapkota, N; Subba, SABSTRACT Polyotia is an anomaly of the external auricle in which the accessory auricle is large enough to closely resemble an additional pinna rather than a skin remnant and cartilage. Polyotia, also known as mirror ear or accessory ear, is a type of ear anomaly in the tragus area, but the term refers to substantial anomalies which resemble an accessory ear, unlike a pre-auricular tag. It is an extremely rare condition and to date, less than 30 cases of polyotia have been reported according to a review of the literature. A variety of theories has been proposed for development of such abnormal external auricle. We report two cases of polyotia which presented to Dhulikhel Hospital ENT OPD that was successfully corrected surgically. An 8-year-old boy and a 14-year-old boy presented with a large accessory anomalous auricle on left and right ear respectively. The accessory auricle was composed of an elastic cartilaginous component covered with skin and was positioned anteriorly to the original auricle in both the cases. The anomaly was not as large as the patient’s external auricle, rather it mirrored the external auricle. On the opposite ear both the cases presented with pre- auricular skin tag. Surgical correction was done by dissecting the skin free from the duplicated cartilage via an incision along the free edge of the helix the duplicated cartilage was contoured to fill the pre-tragal hollow and the tragus reconstructed with a free cartilage graft.
