This report from California (M Sedman, Otolaryngology - Head and Neck Surgery Volume 138, Issue 2, February 2008, Pages 242-245) described a novel minimal access transcanal approach to anterior marginal perforations utilizing anterior canal tympanomeatal flap with / without drilling of anterior canal wall, similar to techniques earlier described by Ugo Fisch for similar perforations

This interesting paper from San Francisco (Mau T & Courey MS, Otolaryngology–Head and Neck Surgery (2008) 138, 221-225) utilized calcium hydroxyapatite in human cadaver to examined the relationship between gender and  site of vocal fold injection in injection laryngoplasty and concluded significant gender difference in both lateral and medical VC injections.

This paper from China (Jianhua Fu et al, International Journal of Pediatric Otorhinolaryngology (2008) 72, 327—332) convincingly reported 5 cases of neonatal lingual thyroglossal duct cysts (LTDC) emphasizing that this diagnosis should remain strong in all newborns presenting with dyspnoea who are commonly believed to have laryngomalacia

LTDC & Laryngomalacia in newborns...?

SUMMARY:

 Objective: To distinguish lingual thyroglossal duct cyst (LTDC) from laryngomalacia in newborn.

Methods: The clinical data of five newborns who were diagnosed as LTDC were retrospectively analyzed.

Results: Inspiratory stridor with chest wall retraction was cardinal symptom of newborn with LTDC. A slightly gray and round cyst with smooth surface at the base of the tongue was found with laryngoscopy. In computed tomography examination of larynx, a well-circumscribed lesion with low intensity was detected at the base of the tongue protruding into the air passage. Pathological examination demonstrated the cyst wall was composed of tabular and columnar epithelium.

Conclusions: LTDC is a common disease in newborns, which is similar with laryngomalacia. For neonate suspected of LTDC, laryngoscopy examination should be taken first, while laryngeal CT scan is an important diagnosis basis to be reg. Cyst puncture can ameliorate the symptoms of LTDC, while surgical removal serves as a radical cure for LTDC

 

 

Summary

Objective:

To report a novel, minimally invasive technique for anterior tympanic membrane (TM) perforation repair.

Study Design

A transcanal repair of the anterior TM was performed on 45 patients.

Methods

A total of 689 patients with chronic suppurative otitis media underwent surgical intervention; of these, 45 patients with isolated anterior TM perforations underwent an anterior tympanoplasty. This approach is similar to a transcanal approach for small posterior perforations; an anterior rather than a posterior flap is raised.

Results

Perforations ranged from 20 to 50 percent in size. Preoperative air-bone gaps ranged from 5 to 51 dB and averaged 25 dB. Postoperative air-bone gaps ranged from 0 to 33 dB and averaged 14 dB. Of 45 patients, 40 (88%) had closure of their perforations. Data from 1- to 10-year follow-up are provided.

Conclusions

The anterior transcanal tympanoplasty is a minimally invasive technique to repair anterior TM perforations. The procedure is simple and obviates the need for a large postauricular incision.

Abstract:

OBJECTIVE: To determine the influence of gender and injection site on the amount of injectate needed to medialize an immobile vocal fold, and to describe the distribution patterns of the injected bolus.

STUDY DESIGN: Surgical intervention in human cadaveric larynges in experimental setting.

SUBJECTS AND METHODS: Cadaveric larynges were injected with calcium hydroxylapatite into the lateral or medial aspect of the vocal fold. High-resolution CT scans were obtained before and after injection.

RESULTS: Males required 50% to 60% more material than females (P
0.03). For both genders, lateral injections required more than medial injections (P  0.001). Laterally injected boluses tended to distribute toward the cricothyroid space, with frank extrusions more common in females.

CONCLUSION: The amount of injectate required to medialize male and female vocal folds is significantly different. The smaller size of the female larynx likely accounts for a higher incidence of extrusion through the cricothyroid space. These gender differences should be taken into consideration when performing injection laryngoplasty.
