Volume and Location of the Defect as Predictors of Swallowing Outcome After Glossectomy: Correlation with a Classification.

This study aimed to characterize the swallowing outcomes after glossectomy and analyze factors affecting them. An attempt is made to propose a classification system and corroborate it to the results. This is a cross-sectional study to assess swallowing in carcinoma tongue patients treated surgically with or without reconstruction, followed by adjuvant therapy as indicated. One hundred and six patients were evaluated with videofluoroscopy (VFS). Volume defects were classified as I: less than one-third, II: one-third to half, III: half to two-thirds, IV: two-thirds to total glossectomy. Location was assigned as lateral, tip, and sulcus defects. Predictors were T stage, surgical approach, volume, location, and adjuvant radiotherapy. Chi-square and logistic regression were used for statistical analysis. Defects were Class I, II, III, and IV in 36, 42, 16, and 12 patients, respectively. Adjuvant radiotherapy was given in 40% of cases. Mean evaluation time was 14 months from treatment. On, Functional Oral Intake Scale (FOIS) score, as the Class of the defect increased, the percentage of patients with low scores (poor swallowing outcomes) showed an increasing trend (p < 0.001). Defect volume, T stage, approach, and radiotherapy correlated significantly with an abnormality of all VFS parameters (p < 0.001). On multivariate analysis, defect volume remained an independent predictor for oral parameters; radiotherapy emerged as the only independent predictor for pharyngeal parameters. The incremental volume of the defect is a significant independent predictor of swallowing. Based on this, we propose a classification for glossectomy.

Challenges in the reconstruction of bilateral maxillectomy defects.

PURPOSE: Bilateral maxillectomy defects, if not adequately reconstructed, can result in grave esthetic and functional problems. The purpose of this study was to investigate the outcome of reconstruction of such defects. MATERIALS AND METHODS: This is a retrospective case series. The defects were analyzed for their components and the flaps used for reconstruction. Outcomes for flap loss and functional indices, including oral diet, speech, and dental rehabilitation, also were evaluated. RESULTS: Ten consecutive patients who underwent bilateral maxillectomy reconstruction received 14 flaps. Six patients had malignancies of the maxilla, and 4 patients had nonmalignant indications. Ten bony free flaps were used. Four soft tissue flaps were used. The fibula free flap was the most common flap used. Three patients had total flap loss. Seven patients were alive and available for functional evaluation. Of these, 4 were taking an oral diet with altered consistency and 2 were on a regular diet. Speech was intelligible in all patients. Only 2 patients opted for dental rehabilitation with removable dentures. CONCLUSIONS: Reconstruction after bilateral maxillectomy is essential to prevent esthetic and functional problems. Bony reconstruction is ideal. The fibula bone free flap is commonly used. The complexity of the defect makes reconstruction difficult and the initial success rate of free flaps is low. Secondary reconstructions after the initial flap failures were successful. A satisfactory functional outcome can be achieved.

Defect components and reconstructive options in composite orbitomaxillary defects with orbital exenteration.

PURPOSE: The conventional way of reconstructing an orbital exenteration defect associated with a maxillectomy is to cover it with a soft tissue free flap and camouflage it with a spectacle-mounted orbital prosthesis. Also, there are some reports on the use of bone flaps. The objective of this study was to review the reconstructive options for a defect resulting after orbital exenteration and maxillectomy. MATERIALS AND METHODS: This study concerns a retrospective case series of 20 patients. Electronic medical records, including clinical details, operative notes, and follow-up data, were analyzed. Defects were analyzed for their reconstructive components. The reconstructive methods used were studied by the types of flap used, bony versus soft tissue types of reconstruction, and the prosthetic method used to rehabilitate the eye. Outcomes were analyzed for flap success rate. Descriptive methods for data analysis were used. RESULTS: Fourteen patients underwent a soft tissue reconstruction alone and 6 underwent bony reconstruction. The free rectus abdominis was the commonest soft tissue flap used. This article presents the outcome of reconstruction in such patients and the utility of individual flaps for their ability to replace different components of the defect. CONCLUSIONS: Ideal reconstruction should address all individual defect components of facial contour, orbital, palatal, skull base, and skin defects. The free rectus abdominis flap remains the common choice. When a composite socket reconstruction is to be achieved, the innovative free tensor fascia lata flap with the iliac crest bone and internal oblique muscle is an option.

Simultaneous cerebrospinal fluid otorrhea and rhinorrhea as a cause of recurrent meningitis in a patient with cochlear dysplasia.

UNLABELLED: Inner ear dysplasia is a rare cause of cerebrospinal fluid otorhinorrhea and presents in a variety of ways, ranging from asymptomatic to recurrent bacterial meningitis. We describe a 6-year-old boy who presented with clear watery nasal discharge and recurrent bacterial meningitis. Magnetic resonance cisternogram showed cerebrospinal fluid leak through the cribriform plate of ethmoid. High-resolution computed tomographic scan of temporal bones confirmed the diagnosis of cochlear dysplasia, with cerebrospinal fluid leak coming through a defect near the oval window and through the eustachian tube orifice into the nose. Surgical closure of the defects was performed successfully. CONCLUSION: Recurrent meningitis in a child should be investigated for inner ear malformations. Awareness of this condition, a high index of suspicion and early imaging can prevent complications and give excellent results in these children.

Facial artery-based islanded myomucosal and bone flaps in head and neck reconstruction.

This article aims to illustrate various applications of facial artery-based islanded myomucosal (iFAMM) and osseous/osteo-myomucosal flaps (iFOMM) in head and neck reconstruction. A retrospective analysis of 75 patients who underwent the reconstruction of various head and neck mucosal defects with iFAMM/iFOMM in a tertiary head and neck cancer department from May 2015 to May 2019 was performed. The patients had surgery for cancer, which involved the oral tongue, floor of mouth, oropharynx, lower alveolus, larynx, hypopharynx, cricopharynx and trachea. iFOMM was used in 3 patients. Functional and esthetic outcomes, short-term and long-term complications were analyzed. The flap was successful in 74 out of 75 patients. Speech was intelligible in almost all patients and majority of patients could take oral feeds without any restrictions. The esthesis of reconstruction was scored high with a mean visual analog scale score of 8.4. The most commonly observed complication was marginal mandibular paresis, which improved with time. Mouth opening was >3 cm in 68/75 patients. Adjuvant radiation was a common factor in patients with <3 cm mouth opening. Flap was sensate by 4 months in majority of patients. The reach, pliability, and esthetics of the flap combined with recoverable morbidity of donor site present in the facial artery-based flap as a good option in the reconstruction of various head and neck subsites. Reduced operative time, lesser complication rates, less financial burden, and simplicity of the procedure make it a cost-effective alternate solution for reconstruction.

Incudostapedial joint arthroplasty using temporalis fascia/perichondrium ties.

Incudostapedial joint dislocation is the most frequently found ossicular chain defect. In these cases reconstitution of joint capsule is important in maintaining joint integrity. But reconstruction of dislocated incudostapedial joint is a challenging procedure as this joint is devoid of any muscular or soft tissue support. Here we describe a technique designed to reposition the incudostapedial joint in its anatomical position using temporalis fascia or perichondrium. Data have been collected and analyzed from 42 patients with incudostapedial joint discontinuity. The fascial ties used for reconstruction of joint capsule ensure a dynamic union of the repositioned incus with stapes, leading to a significant improvement in conductive hearing loss.

Contralateral Islanded Facial Artery Myomucosal Flap for the Reconstruction of Floor of the Mouth Defect.

Reconstruction of floor of the mouth and ventral surface of the tongue defects can be challenging because inadequate correction can lead to mobility restriction of the tongue and resultant impairment of speech and swallowing. Ideal flap should be pliable, provide adequate bulk, be easy to harvest, and cosmetically acceptable. Commonly used ipsilateral facial artery-based myomucosal flaps may not be ideal if facial vessels need resection. We share our experience in a case of simultaneous primary mucoepidermoid carcinoma of right submandibular and sublingual glands, with a postsurgical defect involving floor of the mouth and ventral surface of the tongue, reconstructed with islanded facial artery myomucosal flap raised from left buccal mucosa and tunneled into the right floor of the mouth defect medial to mandible. The case is being reported to share the method of reconstruction as well as for the rare presentation of simultaneous primary mucoepidermoid carcinoma of multiple major salivary glands.

Endoscope-assisted conservative resection and reconstruction in recurrent subglottic carcinoma.

BACKGROUND: Very few cases of conservative laryngectomy in recurrent carcinoma of subglottis postradiotherapy have been reported. Technical aspects of conservative resection and reconstruction in subglottic carcinoma have not been well described. METHODS: Herein, we present a case of recurrent carcinoma of subglottis for which conservative resection with adequate margins was done with endoscope assistance and defect reconstructed by buccal mucosa, conchal cartilage, and temporoparietal free flap. The technique of resection, reconstruction, complications, postoperative outcome, and our suggestions are described. RESULTS: The lesion could be removed with wide margins. Reconstruction could preserve the voice, and deglutition was unaffected. There was no donor site-related complication. Complications were a result of the choice of the stent, which included infection and difficulty in removal. CONCLUSION: Selected cases of recurrent carcinoma of the subglottis can be managed by conservative resection with adequate margins and appropriate reconstruction with good functional outcomes.

Tracheal advancement with myomucosal island flap for partial laryngopharyngectomy defect reconstruction.

BACKGROUND: Restoring the anatomy and function of a partial laryngopharyngectomy with hemicricoid defect is an extremely challenging area in head and neck cancer surgery. Procedures such as tracheal autotransplantation described for these defects are complex and attempted in very few centers. Therefore, the purpose of this article was to share our technique of reconstructing such defects with tracheal advancement with myomucosal island flap for laryngopharyngeal defect (TAMMIL), which allows functional reconstruction of the larynx. METHOD: A 49-year-old man with carcinoma of the right pyriform sinus, postneoadjuvant chemotherapy with progressive disease underwent vertical partial laryngopharyngectomy. The resultant defect was reconstructed with tracheal advancement and islanded facial artery myomucosal (FAMM) flap. RESULT: The patient is 1-year postsurgery, free of disease, decannulated, and taking oral feeds. Video fluoroscopy showed no evidence of aspiration. CONCLUSION: This technique is single-staged, easier compared to existing techniques, aids "like-for-like" reconstruction, and allows surgical organ preservation in selected laryngeal and hypopharyngeal cancers.

Reconstruction of a Combined Maxillectomy and Segmental Mandibulectomy Defect in a Seven-Year-Old with a Single Free Fibula Osteocutaneous Flap.

Combined upper alveolectomy and segmental mandibulectomy are complex defects. Reconstruction of these defects is usually suboptimal. We describe the case of a pediatric patient with vessel-depleted neck with recurrent vascular malformation involving the ramus and coronoid process of mandible and a previous history of maxillectomy and a reconstruction with anterolateral thigh flap. The patient underwent wide resection. The defects involving the upper alveolus and mandible were simultaneously reconstructed with a single free fibula flap.

Pneumosinus Dilatans Helping Subcranial Resection in a Patient with Advanced Ethmoid Malignancy.

Subcranial approach is a useful procedure in the management of limited anterior skull base tumors. But the posterior and superior visualization may be limited, in ethmoid malignancies with a large intracranial extension. A 55-year-old male patient, a case of an ethmoid malignancy, with a large intracranial component was resected with adequate margins by a subcranial approach. The coincident pneumosinus dilatans helped the surgical resection. This case demonstrates that assessment of pneumatization of the frontal sinus is as important as the size and extent of the tumor, while deciding an anterior skull base surgical approach. Even large malignant lesions may be approached subcranially if the frontal sinus is proportionately large. Pneumosinus dilatans, though rare, can be used to the benefit of the patient in selecting a less invasive approach.

Easy and Safe Method for Facial Nerve Identification in Parotid Surgery.

Background A safe and easy anatomical landmark is proposed to identify the facial nerve in parotid surgery. The facial nerve forms the center point between the base of the styloid process and the origin of the posterior belly of the digastric muscle. Objective To evaluate the consistency, accuracy, and safety of the landmark in identifying the facial nerve. Methods The study was designed in three steps: a cadaver study, a radiologic study, and a prospective clinical study. Anatomy was initially studied in two cadavers. Then the images of 200 temporal styloid regions were studied for consistency of the presence of the styloid base. In the second part of the radiologic study, the distance between the styloid base and the origin of the posterior belly of the digastric muscle was studied in 50 parotid regions. The clinical study involved 25 patients who underwent parotidectomy. Results The styloid base was present in all the images studied. The mean distance between the styloid base and the origin of the posterior belly of the digastric was found to be 0.72 cm (range: 0.45-0.99 cm). The facial nerve could be identified consistently and safely in all patients. Conclusion This trident landmark provided safe, accurate, and easy identification of the facial nerve using two fixed bony landmarks.

Giant frontal osteoma: case report with review of literature.

Diagnosis of frontal osteoma is usually by chance, but rarely these can produce exceptional ophthalmologic and neurological complications apart from cosmetic disfigurement. Etiology of frontal osteoma may be multifactorial. Surgical management should be site and size specific. A combination of open surgery and endoscopic methods would help confirm complete removal of the tumor. Here we report a fronto-ethmoidal osteoma of size 7.1 × 5.3 × 5.1 cm which is one of the largest reported in literature. Also, we have done an extensive web search and text based review of the literature on frontal osteoma in terms of its incidence, etiology, pathology, clinical presentation, complications and important developments in management. The available literature and our own experience suggest that even large osteoma arising in the fronto-ethmoid region can be completely removed surgically with minimum complications. The surgical approach can be varied according to the extent of the tumor and patient considerations. A regular follow up is necessary in asymptomatic cases being treated conservatively, in view of the potential complications.

Cerebrospinal fluid rhinorrhea: endoscopic repair based on a combined diagnostic approach.

BACKGROUND: The treatment of cerebrospinal fluid rhinorrhea has evolved since the first recorded instance of this condition by Willis in 1676. The advancements in radiology and endoscopic nasal surgery have provided ways to solve this potentially dangerous condition. But even now quite a few questions remain unanswered while tackling this difficult clinical situation. Laboratory tests for confirming the presence of cerebrospinal fluid in nasal fluid can yield false positive results and radiological evaluation has never been foolproof when it comes to small leaks and multiple leaks. Also the postoperative recurrence needs to be brought within acceptable limits. OBJECTIVES: We have tried to evaluate endoscopic repair of CSF rhinorrhea based on a combined diagnostic approach. The methods for diagnosis of CSF rhinorrhea have been reevaluated based on our experience with a view to prevent recurrences and complications. MATERIALS AND METHODS: The study group included twenty patients of CSF rhinorrhea who have been treated by endoscopic repair and spans over a period of five years from January 2001 to December 2005. A combination of retrospective and prospective methods of study has been used. Patients have been subjected to laboratory, radiological and dye studies for confirmation and localization of leak. Endoscopic repair of CSF fistula with composite graft and fibrin glue has been performed. Postoperative management included intracranial pressure reducing measures and control of primary condition in cases of spontaneous leak. RESULTS: Endoscopic repair of CSF rhinorrhea produced a first time success rate of 92%. CT/MR Cisternogram could localize the defect in 85% cases while intrathecal fluorescein aided localization whenever it was used. The use of fibrin glue with composite graft and postoperative intracranial pressure reducing measures could improve the success rate. CONCLUSION: Management of a suspected CSF leak requires a combined diagnostic approach. Endoscopic repair with composite graft and fibrin glue should be the first line of management in cases of CSF rhinorrhea requiring surgical closure. Intracranial pressure reducing measures play an important role in preventing postoperative recurrence.
