Mucormycosis is caused by saprophytic fungi belonging to the species mucorales. The disease commonly affects patients with immunocompromised states such as uncontrolled diabetes, blood disorders and organ transplantation recepients. The usual mode of management is by using antifungals such as amphotericin B and surgery in the form of debridement of the necrotic tissue. A study was conducted on patients of mucormycosis during the pre-Covid-19 and Covid-19 era to evaluate the effectiveness of the Sandwich Therapy of amphotericin B. The mortality rate was found to be 3.57% during the pre- Covid-19 period and 18.8% during the Covid-19 period. This is very low as opposed to 50% quoted by many other studies. The Sandwich Therapy as discussed above for extensive mucormycosis can be useful in curtailing the disease already established to its present location and preventing its further spread either naturally or by the act of debridement per se. It also provides a sustained anti fungal umbrella in the blood to deal with the disease at microscopic level in the blood stream thus reducing mortality.

Background: Radiation treatment can modify soft tissue dynamics depending on the extent and location of irradiation. We hypothesized that head and neck radiotherapy caused alterations in cricothyroid membrane (CTM) related dimensions.

Objectives: Primary objective was to evaluate changes in the cricothyroid membrane height (CTMH) and skin-to-CTM distance (STCD) in patients who underwent radiation treatment for head and neck cancers.

Methods: Pre- and post-head-and-neck cancer-radiated computed tomography (CT) scans were analyzed retrospectively. The patients' demographics (age, sex, body mass index, cancer location), radiation dose and laterality, time from radiation initiation to CT scan assessments were summarized. CTMH and STCD were measured from pre-and post-radiation CT scans. Pre- and post-radiation comparisons were conducted using a paired t-test, or Wilcoxon signed-rank test if more appropriate. Chi-squared or Fisher's Exact test were used for categorical variables.

Results: Among 231 study patients, who underwent head and neck radiotherapy in our institution 73.2% were males, and the median age of total population was 66 years (31-93). The median BMI was 25.2 kg/m² (13.8-47.2). The median time from first radiation dose to CT scan assessment was 29.5 months (2-115).The median pre- and post-radiation CTMH were 8.7 mm (3-16.2) and 7.5 mm (3.1-14.3) respectively. The median pre- and post-radiation STCD were 11.7 mm (2.9-71.1) and 10.2 mm (3.9-38) respectively.

Conclusion: In summary our patient population had significant reduction of cricothyroid membrane related dimensions following head-and-neck radiotherapy, which can limit the localization of the cricothyroid membrane.

Level of evidence iii: Retrospective cohort study.

This study was undertaken to assess the outcome of canal wall window tympanomastoidectomy in chronic suppurative otitis media in a tertiary care centre of central India. A total of 50 patients were taken for this study in which the youngest patient was 13-year-old male and oldest 55-year female. Maximum patients were in between age group 10 to 20 years, 20 (40%) patients and minimum 03 (6%) between age group 51 to 60 year. The study mainly emphasized on: To study the clinical profile of the cases of chronic suppurative otitis media, to study the hearing outcome after 3 months of Canal wall window tympanomastoidectomy technique, to study the post-operative condition of ear after 3 months whether dry or wet and to study the post-operative follow up of cases to assess the graft uptake. Average PTA & ABG improvement of different tympanoplasty was also calculated in our study in which Type I tympanoplasty had 12.20dB gain, Type II of 10.50 and Type III of 10.31dB.An overall average improvement in all patients with tympanoplasty was 11.00dB.At the end of the study 100% dry ears were achieved. The technique of canal wall window tympanomastoidectomy involves formation of a window in the outer attic wall to look at the disease extent which was then closed by a snuggly fitting cartilage.It is a novel technique & without compromising the structural integrity in case of a limited disease which is only extending till attic and aditus good anatomical and hearing results could be gained.

The present study aimed to assess the central auditory processing abilities and working memory in children with non-syndromic cleft lip and palate (NSCLP) and to compare with the developed normative and craniofacially normal peers. Sixteen NSCLP children aged 7 to 12 years and fifteen craniofacially normal peers were recruited in this study. Speech perception in noise Kannada (SPIN-K), gap detection threshold (GDT), dichotic consonant-vowel (DCV), and masking level difference (MLD) tests were administered to assess various central auditory processing abilities. Working memory abilities were assessed by using forward-digit span and backward-digit span tests. The results showed significant differences in SPIN-K, dichotic CV, GDT, forward digit, and backward digit span scores between children with NSCLP and craniofacially normal peers. Thus, it can be concluded from the present study that children with NSCLP have a risk of developing auditory processing deficits. To conclude, assessment of central auditory processing abilities in children with NSCLP is recommended.

Since 1952, myringoplasty has evolved with various surgical techniques, including overlay, underlay, sandwich, pegging, rosette, and plugging. Overlay and underlay methods are most commonly used. In 1998, Eavey introduced the cartilage and perichondrium butterfly inlay myringoplasty, designed for small to medium-sized perforation closure, offering practical advantages such as reduced surgical time and improved hearing outcomes. A one-year prospective study (September 2022 to September 2023) in a tertiary care hospital in India involved 30 patients aged 9-52 years with inactive small central perforations. Pre-operative pure tone audiometry (PTA) results were required to be no higher than 35 dB conductive hearing loss. General or local anesthesia was used based on the patient's age. The surgical technique involved visualizing the perforation, graft preparation, and transcanal insertion. Among the 30 patients, the graft uptake rate was 100% at 3 months and 93.33% at 6 months. Pre-operative mean PTA was 29.76 dB, which decreased to 25.03 dB post-operatively, with a statistically significant air-bone gap closure of 4.73 dB. Cartilage rosette inlay-onlay myringoplasty offers an effective solution for small to medium-sized perforations, achieving high success rates (93.33%). This technique is associated with reduced surgical time, suitability for day care surgery, and minimal scarring, making it a valuable addition to routine clinical practice.

Low-grade myofibroblastic sarcoma (LGMS) of the larynx is an extremely rare entity. We report a case of LGMS in a 59-year-old man presenting with progressive hoarseness and a right laryngeal mass and there was no recurrence during the 6-month follow-up after the total laryngectomy.

Introduction: Head and neck malignancies are associated with poor prognosis and poor quality-of-life if detected late. Narrow-Band-Imaging(NBI) is one of the important tools, which helps in detecting these lesions earlier. By using narrow-wavelength(400-550 nm) it enhances the mucosal and submucosal vascularity against the pale mucosal background which helps us detecting benign, pre-malignant and malignant lesions.

Objective: The objective of this study was to evaluate the accuracy of NBI in the diagnosis of various mucosal lesions of head and neck region and its correlation with the histopathology reports.

Materials and methods: This was a prospective diagnostic study conducted between June 2020 - June 2022 where 118 patients(oral cavity-28, laryngeal-87,and hypopharyngeal-3) who fulfilled the inclusion and exclusion criteria were recruited. All-118-patients underwent NBI endoscopy under local/general anaesthesia followed by biopsies from the most suspicious-areas. Type of vascular-pattern noted from NBI and their respective histopathological reports were correlated.

Results: The mean age was 53.28 ± 1.24 years ranging from 16 to 88 years. The sensitivity, specificity, Positive-Predictive-Value(PPV) and Negative-Predictive-Value(NPV) in detecting benign lesions were 100%, 90%, 74% and 100% respectively. The sensitivity, specificity, PPV and NPV in detecting premalignant lesions were 70%, 92%, 56% and 96% respectively. The sensitivity, specificity, PPV and NPV in detecting malignant lesions were 83%,97.5%, 98.5% and 97.5% respectively. NBI has a strong association with the histopathological reports, which is statistically significant(p-value < 0.001).

Conclusion: NBI has high specificity and negative predictive value in detecting and classifying various mucosal lesions of head-neck region. Its findings had a strong correlation with histopathological reports.

Mastoid surgeries are surgical procedures, wherein surgical failures are prevalent due to the fundamental complexities involved, especially in the understanding of microscopy and pathophysiology of the disease. A revision mastoidectomy is an utmost, a post-procedure decision, wherein the patient continues to exhibit signs and symptoms that are concerning. This is proved by a prospective, cross-sectional research which was conducted upon a group of patients who were referred to a tertiary health care centre. This selection of twenty-three (23) patients who underwent mastoidectomy prior to their participation in this research, were exhibiting signs of recurrent diseases. The observations of trends seen in revision mastoidectomy are detailed and inferences gleaned from it. These trends and observations direct us towards the understanding that the majority of failure of previous mastoidectomy was due to persistent diseased air cells and recurrent or residual cholesteatoma. This is further corroborated by the trends observed from exhausting literature readings of previous similar studies. Revision mastoid surgeries are an important follow-up process, after the mastoidectomy, if the patients continue to exhibit diseased states.

A notch is defined as the frequency point at which hearing loss is greater than 15 dB when compared to one octave above and below. C3 dip or 1 kHz notch is rarely seen and not much information is known about the clinical profile of such condition. The aim of this case report is to highlight the audiological profile of a case with 1kHz notch and discuss the possible causes for the same. Case A (16 yrs) was referred with a complaint of hearing loss and speech understanding difficulty specially at school. The teen had taken multiple medications for several health related issues like malaria, appendicitis and the understanding difficulty was evident during this period. Detailed audiological evaluation revealed a significant C3 dip in the right ear and normal hearing sensitivity in the left ear. Evidences from literature suggests strong correlation between drugs like Cefotetan, cefotaime, piperacillin, ampicillin (appendicitis treatment) and chloroquine (malaria) and hearing loss. Hence, we concluded that the possible cause of 1khz is ototoxic medication.

Internal carotid artery injury is one of the most feared intraoperative complications of endoscopic sinus surgery and endoscopic skull base surgery. Vidian canal is used as a landmark to identify laceral genu of ICA. But, this structure leads to the lateral aspect of the genu and so, there is still a possibility of injuring the genu, if we blindly follow this landmark. So, to find out a more reliable landmark to locate ICA, we conducted a computed tomography-based study in our institution. The aim was to evaluate the anatomical variations in position of palatovaginal canal in relation to laceral genu of ICA. The primary objective was to know the anatomical relation of medial opening of PVC to laceral genu of ICA, and the secondary objective was to measure the distance between these two structures. CT paranasal sinus images of 105 patients were collected and axial cuts evaluated to find out the anatomical relation between PVC and ICA. In 97.1% of the scans, laceral genu of ICA was found lateral to medial opening of PVC, and in the rest 2.9%, both structures were found to lie in the same line. In 62.9% of the patients, the distance between the two structures was found to be between 3.1 and 6 mm. The inter-palatovaginal canal corridor can possibly be considered as a safe corridor to clival region of sphenoid sinus. This corridor can be easily identified intraoperatively during endoscopic skull base surgeries So, if the surgeon limits the instrumentation to the inter-palatovaginal canal corridor, iatrogenic injury to ICA, one of the most dreaded complications, can be avoided, while working in the clival region of sphenoid sinus.
